- Such electromagnetic actuators are known, for example, in the form of electromagnetic switching or valve devices, such as in the form of an electromagnetic relay or solenoid valve.
- Solenoid valves for example in the form of tilting armature valves, are used, for example, as control valves for regulating the pressure of air, for example in a vehicle, for example in a commercial vehicle or bus for passenger transport.
- a brake system for a vehicle with an electronic service brake system includes at least one control valve for pressure regulation.
- the tilting armature valve has a coil element with a coil core and a coil arranged circumferentially around the coil core, as well as an armature, which is mounted on an end face of the armature by means of a bearing, the armature, in particular by applying current to the coil, from a first Position is movable into a second position. Furthermore, a valve seat with an outlet and an inlet for a fluid are provided, the outlet being fluid-tightly closable in the first position of the armature by means of a sealing element and the outlet being released in the second position of the armature.
- a spring is provided for pressing the armature against the coil element or a housing of the toggle armature valve.
- Other types of solenoid valves are also known, as described, for example, in DE 10 2014 115 207 A1, DE 10 2018 123 997 A1, or DE 10 2014 115 206 B3.
- the magnetic coils and the magnetic cores (coil cores) that act to reinforce the magnetic force are designed, for example, with a round or cylindrical cross-section due to the positive material/surface ratio. This achieves an even distribution of the magnetic flux within the magnetic core.
- the well-known shape of the coil core is the reason why the transition of the magnetic flux from the magnet core to the yoke is often uneven.
- yoke armature magnets such as e.g. tilting armature magnets
- the present invention is based on the object of specifying an electromagnetic actuator of the type mentioned in the introduction, in which it is possible to increase the magnetic force that can be used for the movement of the actuator element that is to be activated.
- the invention relates to an electromagnetic actuator of the type mentioned in the opening paragraph according to the appended patent claims.
- Advantageous training and developments of the invention are specified in the subclaims and the following description.
- one aspect of the present invention relates to an electromagnetic actuator with a coil element, which has at least one coil core and a coil arranged circumferentially around the coil core, the coil core having a rotationally symmetrical first region with an axis of symmetry, in which the coil core is surrounded circumferentially by the coil .

- the invention makes it possible to increase the magnetic force that can be used for the movement of the actuator element to be activated in a generic electromagnetic actuator by, on the one hand, weakening the magnetic flux in the direction of the bearing through targeted positioning and design of the magnetic transition between the coil core and the armature body (yoke). , while the usable magnetic force at the other end of the anchor body is increased. This also has a positive effect on the torque acting on the armature body as a result of the magnetic force, which is increased on the second side of the coil core away from the bearing.
- This targeted positioning and design of the magnetic transition between the coil core and the armature body can basically be used with all electromagnetic actuators in connection with yoke armature magnets mounted on one side, such as e.g. tilting armature magnet valve and switching devices.
- This enables optimization of electromagnetic actuators with yoke armature magnets (such as e.g. tilting armature magnet) as a drive for e.g. relays, lifting armatures and solenoid valves.

- the end geometry of the coil core is provided with an additional step in the second area, advantageously to a maximum possible diameter close to the outer circumference of the coil winding.
- Such an additional shoulder directs the field lines of the magnetic field more strongly in the direction of the second side of the coil core, which on the one hand increases the torque acting on the armature body at this point and on the other hand relieves the bearing of part of the magnetic force generated.
- the coil core in the second area for example the additional step, radially covers more than half of the radial extent of the coil winding, which is arranged circumferentially around the coil core.
- the coil core is designed in the second region in such a way that a centroid of the coil core is displaced in the opposite direction from the bearing device relative to the axis of symmetry.
- the storage device is arranged radially outside of the coil core.
- the armature body has a first area in which the armature body is mounted in the actuator by means of the bearing device, and a second area that extends over the second area of the coil core, the armature body in the first Area has a reluctance per unit length, which is increased in relation to a reluctance per unit length in the second region of the anchor body.

- FIG. 2 shows a schematic cross-sectional illustration of an embodiment of an electromagnetic actuator according to the invention, as can be used, for example, in a tilting armature valve according to FIG.
- FIG. 1 shows a simplified cross-sectional view of a tilting armature valve 100 according to an exemplary embodiment in which an electromagnetic actuator according to the invention, as shown in FIG. 2 , can in principle be used.
- 1 is intended to illustrate an exemplary, practical use of an electromagnetic actuator using a tilting armature valve.
- the configuration of the coil core, the armature body and other components according to the invention is shown in more detail in FIG. 2 according to an exemplary embodiment and can in principle be readily transferred by a person skilled in the art to a tilting armature valve according to FIG.
- the tilting armature valve 100 can be an exemplary embodiment of a tilting armature valve 100 shown in DE 10 2016 105 532 A1.
- this can be a solenoid valve provided with reference number 100 in FIG. 1 there.
- other exemplary embodiments are also conceivable, for example in connection with solenoid valves as described in the other publications mentioned above.
- Related configurations of a solenoid valve described in DE 10 2016 105 532 A1 and its components as well as their use are also part of the disclosure of the present invention by reference.
- FIG. 1A shows a cross-sectional view through a toggle armature valve 100 according to an embodiment, in which the armature is in the first position.
- the tilting armature valve 100 has a coil element 110, an armature body (or armature for short) 115, a spring 120, a sealing element 125 and a cover shell 130.
- the coil element 110 comprises at least one coil core 135 and a coil 140 which is arranged circumferentially around the coil core 135 and has a package of coil windings (not explicitly shown).
- An end face of the armature 115 is supported by a bearing 145 .
- the armature 115 is moveable between a first position 147 and a second position 149 .
- the armature 115 is designed to be moved from the first position 147 into a second (tightened) position 149 when the coil 140 is activated.
- the armature 115 can be held in the second position 149 .
- the sealing element 125 is arranged on the side of the armature 115 facing away from the coil element 110 .
- a valve seat 150 with an outlet 155 and an inlet 157 for a fluid 158 is formed in the cover shell 130 .
- the outlet 155 can be closed in a fluid-tight manner by means of the sealing element 125 when the armature 115 is arranged in the first position 147 .
- the sealing element 125 can also act as a damping element in order to prevent the armature 115 from striking the valve seat 150 .
- the sealing element 125 can be attached to the armature 115 or a carrier element by vulcanization. It is also conceivable that an angle is generated when the armature 115 or sealing element 125 hits the valve seat 150 by means of an inclined nozzle or an obliquely shaped sealing element 125 or a curved armature 115 .
- a nozzle which is not explicitly shown in FIG. 1A, does not necessarily have to be integrated into the tilting armature valve 100, but can also be provided by external housing parts.
- valve seat 150 is arranged in the coil element 110, although this is not shown explicitly in FIG. 1A for reasons of clarity. In this case, an actuator would then be advantageous that mediates a release of the output through the armature 115.
- armature 115 has at least one at least partially round elevation 160 in a bearing section 162, elevation 160 advantageously engaging in a recess 165 or opening that is arranged in a section of a housing 170 of tilting armature valve 100 that is opposite elevation 160.
- the armature 115 can slide in the recess during a movement from the first position 147 to the second position 149 after switching on a current flow through the coil 140 and is at the same time in a fixed position in the housing 170 or in relation to the cover shell 130 held.
- the recess is advantageously designed in a trapezoidal manner so that the lowest possible friction is caused when the elevation slides over the surface of the recess 165 .
- the recess 165 can be made of plastic material, for example, and can therefore be produced very easily and inexpensively.
- the spring 120 is designed as a leaf spring and is arranged in the bearing section on a side of the armature 115 opposite the coil 140 .
- the spring 120 serves to press the bearing ball(s) pressed into the armature 115, for example, into the (e.g. trapezoidal) mating shell or recess 165 in the housing 170 of the coil element 110 without play.
- the armature 115 can be fixed by the spring 120 so that the armature 115 is held by the spring 120 in a predetermined position.
- FIG. 1B shows a cross-sectional view through a toggle armature valve 100 with the armature 115 in the second position 149.
- a current is switched on through the coil 140 and the armature 115 is attracted, so that a magnetic field represented by the field lines 180 builds up.
- the armature 115 can fall back into the first position 147, for example as a result of gravity or a spring force of the restoring spring shown.
- the core shape of the cylindrically shaped coil core 135, as shown in FIG. 1, is the reason why the transition of the magnetic flux (exemplified by the field lines 180) from the magnetic core to the yoke runs unevenly.
- the effective magnetic force on the part of the sealing element 125 is thus reduced or even weakened, and the bearing section 162 is also additionally subjected to magnetic forces, which is undesirable in many designs of actuators.
- FIG. 2 shows a schematic cross-sectional illustration of an embodiment of an electromagnetic actuator according to the invention, as can be used, for example, in a tilting armature valve according to FIG. 1 .
- Identical, equivalent or analogous components are denoted in FIGS. 1 and 2 with the same reference symbols.
- electromagnetic actuator 105 has a coil element 110, in which coil core 135 has a rotationally symmetrical first region 136 with an axis of symmetry 137, in which coil core 135 is surrounded circumferentially by coil 140 and a second area 138, which extends radially beyond the first area 136, ie at least on one side of the coil core 135 has a radial extension which goes beyond the radial extension of the first area 136.
- the coil core is thus, for example, formed cylindrically around the axis of symmetry 137, similar to the coil core 135 according to FIG. 1, but not in the second region 138.
- a second region 138 of the coil core 135 that is asymmetrical to the axis of symmetry 137 is additionally provided for asymmetrically influencing the magnetic field.
- the second region 138 of the coil core 135 is formed step-like, starting from the first region 136, essentially on one half of the rotationally symmetrical (cylindrical) region 136.
- the second area 138 can be rectangular or partially round, e.g. semi-circular, when viewed from above, or can be designed with another geometric shape, for example with a geometric shape (e.g.
- the armature 115 is mounted on one side in the actuator 105 by means of the mounting device 106 .
- the bearing device 106 is arranged radially offset from the axis of symmetry 137 of the coil core 135 and is fixed in the actuator 105, preferably radially outside of the coil core 135 or outside its circumference, for example on the coil element 110.
- the armature 115 extends from the bearing device 106 radially over the coil core 135 from a first side 131 to a second side 132 of the coil core 135.
- the second side 132 is the first side 131 radially opposite.
- the armature 115 is moved from the first position 147 (which may be level or slightly tilted as shown in FIG. 1A) to the second by activating the coil element 110 (current flow in the coil 140).
- attracted position (analogous to position 149 in Fig. 1B; not shown in Fig. 2) moves, thus attracted to the coil 140 down.
- the air gap 190 in the direction of the axis of symmetry 137 between the coil core 135 and the armature 115 is smaller on the second side 132 of the coil core than on the first side 131.
- Rm Rm,iron + Rm,air.
- iron is intended to summarize the armature material and the material of the coil core 135 and the housing 170. These components can be composed of the same or different magnetically conductive materials.
- Such an additional shoulder in the second region 138 directs the field lines 180 of the magnetic field more strongly in the direction of the second side 132 of the coil core 135, which on the one hand increases the torque acting on the armature 115 at this point, and on the other hand the bearing device 106 from one Part of the generated magnetic force relieved.
- the coil core advantageously covers 135 in the second region 138, that is to say the additional step shown, radially more than half of the radial extension of the coil winding 141, which is arranged circumferentially around the coil core 135.
- the additional shoulder or head of the coil core 135 can be formed in the second region 138 up to or close to the housing 170 .
- the coil core 135 is advantageously designed in the second region 138 in such a way that a centroid of the coil core 135 is displaced in the opposite direction from the bearing device 106 with respect to the axis of symmetry 137 .
- the invention thus makes it possible to increase the magnetic force that can be used for the movement of armature 115 to be activated, by designing the magnetic transition between coil core 135 and armature 115 in such a way that, on the one hand, the magnetic flux in the direction of bearing device 106 can flow through a larger air gap 190 is weakened, the usable magnetic force on the opposite side of the armature 115, however, is increased.
- This also has a positive effect on the torque acting on the armature 115 as a result of the magnetic force, which is increased on the second side 132 of the coil core 135 away from the bearing device 106, since the field lines 180 and thus the center of force in the direction of the second side 132 a larger radius of the armature 115 are shifted.
- This also has the positive effect that the additional magnetic forces acting on the bearing device 106 are reduced.
- the displacement of the field lines 180 in the direction of the second side 132 of the coil core 135 can be increased by the armature 115 having a magnetic resistance per unit of length in a first region 116, which in relation to a magnetic resistance per unit of length in a second region 117 of the Anchor 115 is increased.
- the armature 115 is mounted in the actuator 105 by means of the bearing device 106, in the second area 117 the armature 115 extends over the second area 138 of the coil core 135.
- the magnetic resistance per unit length is therefore close to the bearing higher than in the area of the paragraph of the coil core 135. Also because of this the field lines 180 can be shifted in the direction of the second side 132 to a larger radius of the armature 115 .
- the magnetic reluctance per unit length can be increased by providing at least one cross-sectional constriction 118 in the first region 116 of the armature 115 in relation to a cross-section in the second region 117 of the armature 115 . Since the reluctance Rm is inversely proportional to the cross-sectional area of the armature material that the field lines 180 must penetrate, Rm, iron per unit length in the first region 116 of the armature 115 through the cross-sectional constriction(s) 118 is higher than in the second region 117. In addition By offsetting the cross-sectional constrictions 118, as shown in FIG. 2, the path for the field lines 180 to traverse can be lengthened by the curvatures thus induced, which in turn increases the magnetic reluctance, which is proportional to the length traversed.
- the respective cross-section of the armature 115 is reduced in relation to a cross-section of the armature body material adjoining the cross-sectional constrictions 118 on the side of the second region 117 .
- the cross-sectional constriction(s) 118 has or have a smaller thickness d1 of the armature 115 (in the direction of the axis of symmetry 137) in relation to the thickness d2 in the second region 117 of the armature 115.
- the cross-sectional constriction(s) 118 can be produced by a reduction (indicated by 119 in FIG. 2 ) of the anchor body material in the first region 116 .
- the reduction 119 (for example in the form of a cavity, a recess or a depression) is produced, for example, by notching, embossing and/or punching out anchor body material.
- a cross-sectional constriction 118 is positioned over the bearing axis of rotation of the bearing device 106 and/or adjacent to the bearing axis of rotation of the bearing device 106, as shown in FIG.
- the magnetic flux is advantageously weakened in the direction of the bearing.
- the usable magnetic force can be increased and the bearing force can be reduced with the resultant lower bearing friction.
- the armature 115 is designed as a plate armature, as is used, for example, in a tilting armature valve 100 according to FIG.
- the armature 115 is fixed and supported on one side, in the present exemplary embodiment on the front side, by means of the bearing device 106 in the actuator 105, for example the tilting armature valve 100, and is moved between the first and second position by activation of the coil 140, as in reference described on fig.
- the bearing device 106 with the bearing axis of rotation perpendicular to the axis of symmetry 137 of the coil core 135 is shown in FIG. 2 differently from the bearing section 162 and bearing 145 of FIG.
- Various mechanisms can be used for storage, such as that shown in Fig. 1 or other mechanisms of the references mentioned above.
- the actuator 105 according to FIG. 2 was described in conjunction with FIG. 1 in connection with a solenoid valve in the form of the tilting armature valve 100 .
- the armature 115 shown in FIG. 2 could be used, for example, as an electrical switching element which closes or opens an electrical contact analogous to a valve opening.
- the type of magnetic field displacement described by the design of the coil core 135 and the armature 115 can in principle be used in all generic electromagnetic armature valve devices and switching devices.
