Definitions
- Electromagnetically actuated actuators in particular such actuators for actuating gas exchange valves on internal combustion engines are known, for example from EP-A-O 043 426 and EP-A-O 197 357. Die aus designs known from these publications, however, have specific power-to-weight ratio and a high space requirement, so that when used as actuators for gas exchange valves on modern internal combustion engines, in particular those with multi-valve operation cannot be used.
- the invention has for its object the known electromagnetic actuators in their construction simplify and thus to a more compact space-saving Design.
- Electromagnetic actuator with the specified in claim 1 Features.
- This design enables effective Utilization of the pole faces, resulting in a more compact form of the Actuator leads overall.
- Another advantage of this Design is that when used as an actuator for a gas exchange valve on an internal combustion engine, the gas exchange valve forming the actuator as before, provided with a valve spring acting in the closing direction can be, as before, on one with the shaft of the Gas exchange valve connected spring plate acts so that the valve can be pre-assembled in the engine block.
- the valve spring also serves as one of the return spring elements the actuator.
- the other spring element acts on the Push rod on the anchor of the adjusting device and sets an integral part of the actuator
- the push rod firmly connected to the anchor and the one with the Gas spring valve connected to the first spring element are divided executed and are non-positively connected.
- the anchor can be connected to the fixed one Part of the push rod a purely axial movement run while the gas exchange valve connected to the spring element for example when using a coil spring as a spring element without influencing the armature can perform spring rotation occurring during the movement.
- a particularly advantageous embodiment is due to the features of claim 2 given.
- the two against each other acting spring elements only on the the actuator facing side of the electromagnet are arranged, wherein one spring element on the push rod and the other spring element acts on an approach on the actuator and that the Push rod and the approach are non-positively connected and the one spring element is the other spring element grips telescopically, the overall height can be reduced.
- the solenoid in each case is connected to a laminated yoke body, so that the formation of eddy currents is reduced.
- one of the two electromagnets in the direction of movement of the anchor slidably mounted and with a Actuator is connected, which is an additional electromagnetic has and by which the distance of the facing each other Pole surfaces of the two electromagnets can be changed is, the displaceably mounted electromagnet in cooperation with the second spring element acting as a return spring be held in two different end positions can.
- the push rod 8 is in a bore 9 of the electromagnet 1 and a bore 10 of the electromagnet 2 out.
- the electromagnet 1 is at its end facing away from the armature 7 provided with a lid-shaped housing 11, which serves as an abutment for a spring 12, which is related to its other End supported on a plate 13 which 8.2 with the push rod is firmly connected.
- the end face 14 of the electromagnet facing away from the armature 7 2 is an actuator 15 to be actuated, here a gas exchange valve turned towards an internal combustion engine.
- the valve stem 16 of the gas exchange valve 15 is more common Way out in the cylinder head 17.
- the free end of the valve stem 16 is here with a plate-shaped extension 18 firmly connected as an abutment of a spring element 19th serves, with its other end on the cylinder head 17 supports.
- the spring element 19 is here just like that Spring element 12 is designed as a helical compression spring, so that both spring elements act against each other, the spring element 19 at the same time as a closing spring for the gas exchange valve serves.
- the spring element 12 on one side and the spring element 19 on the other side of the armature 7 are now designed that the equilibrium position of the armature 7 approximately in the middle between the two opposite pole faces 5 and 6 of the electromagnets 1 and 2.
- the spring element 12 be designed with a progressive characteristic so that the Equilibrium position from the center position towards moves on the electromagnet 1 and thus a simpler Starting is possible.
- the power supply is now to Electromagnet 1 switched off and the power supply to the electromagnet 2 switched on after a certain time.
- the armature 7 is no longer on the pole face of the Electromagnet 1 held so that the spring 12 in the armature Direction towards the middle position between the two pole faces the magnets 1 and 2 can move.
- the Spring element 19 loaded.
- FIG. 2 shows a spring arrangement according to the invention, starting from a magnet arrangement like that 1, both spring elements 12 and 19 on the end face of the underlying facing the actuator 15 Magnets 2 are arranged.
- Anchor 7 is over see push rod 8 with a bell-shaped trained abutment element 13.1.
- the spring element 12 is supported with one end on the free edge 13.2 of the abutment 13.1 and with its other End on the end face 14 of the magnet 2.
- the one with the Valve stem 16 connected plate-shaped extension 18 is located itself within the bell-shaped abutment 13.1 and here, as described with reference to FIG. 1, via the Spring element 19 supported on the surface of the cylinder head 17.
- FIG. 3 is an embodiment of an electromagnetic Actuator for actuating a gas exchange valve shown, which is provided with a spring arrangement j, such as it was described with reference to FIG. 2.
- the one shown in Fig. 3 The arrangement in turn has an upper electromagnet 1 and a lower electromagnet 2, which are at a distance are arranged to each other and between which an anchor 7 is guided axially movable, the on his push rod 8 the valve stem 16 of the gas exchange valve 15 can act.
- Electromagnet 2 displaceable in the direction of the double arrow 20 stored and connected to an adjusting device 21, the in the embodiment shown here essentially by an additional magnet 22 an anchor plate 23 and one connected to the electromagnet 2 to be moved Coupling element 24 is formed.
- the electromagnet 1 and the Additional magnet 22 are here indicated schematically Carrier 26 rigidly connected to the cylinder head 17.
- the additional magnet 22 is de-energized, the effect a corresponding return spring of the slidably mounted Electromagnet 2 pressed against a spacer 27, of the clear distance between the two pole faces 5 and 6 and thus specifies the possible stroke of the armature 7. in this connection is the anchor plate 23 of the adjusting device in Height of the position line 28 shown in dashed lines
- the illustrated embodiment forms the second spring element 12 also the return spring.
- the "working direction" of the additional magnet should be made in this way be that the position of the sliding magnet currentless additional magnet corresponds to normal operation.
- Sets the operating mode with a short stroke of the armature 7 "Normal operation” is then the anchor plate 23 in the dashed position acc. Fig. 3.
- Represents the mode of operation with a long stroke represents "normal operation”, the anchor plate 23 arranged on the other side of the additional magnet 22 his.
- a magnetically actuated actuating device 21 can also be a mechanical, hydraulic or pneumatic adjustment of the stroke length of the armature 7 by moving of the magnet 2 may be provided.
- coil springs can also use torsion springs or spiral springs, for example Leaf springs are used.
- the magnets can have a circular cross section in horizontal section, but also a rectangular or square cross section exhibit. The latter is favorable for the laminated yoke body.
