Definitions
- the present invention relates to a valve for blocking and releasing a flow path, which can be actuated by means of an electromagnetic actuator unit.
- valves are used, for example, as Schubumluftventi le on the turbocharger in motor vehicles in order to release a bypass to the intake side in overrun operation.
- Schubumluftventi le on the turbocharger in motor vehicles in order to release a bypass to the intake side in overrun operation.
- rapid opening and closing operations of the valve are sought.
- valves on the turbocharger are designed either as flap valves actuated by a drive motor with a gear or as slide or piston valves.
- Membrane valves are also common. Flap valves have the advantage that they allow intermediate positions of the flap, which can be set with the help of a corresponding sensor system and allow partial openings of the bypass line. However, this requires considerable technical effort.
- Slider or piston valves have the advantage that they have a particularly simple structure and are therefore inexpensive and also have good response behavior. However, they conventionally only allow a completely closed or a fully open position.
- the invention is therefore based on the object of specifying a valve for blocking and releasing a flow path, which is suitable for use as a recirculation valve on a turbocharger egg nes motor vehicle and which is also simply built up, works reliably and reliable control of the mass flow in a bypass line allowed.
- This object is achieved with the subject of the independent claim.
- Advantageous further developments result from the dependent claims.
- the spring device has at least one spring compressible with a first spring rate starting from a completely closed position of the valve to a partially open intermediate position of the valve and a second spring rate starting from a partially open intermediate position of the valve to a fully open position of the valve compressible spring.
- the first spring rate is different from the second spring rate.
- the valve has the advantage that, in a technically particularly simple manner, it is possible to assume intermediate positions of the closure body, in which the flow path is partially blocked, so that a completely open reduced mass flow through the bypass line.
- the electromagnetic actuator unit can then be controlled such that it first provides a relatively small first force Fl on the armature and thus on the spring compressed by the closure body.
- the first force Fl is dimensioned such that it is sufficient to overcome the counterforce exerted by the spring with the first spring rate, but not the counterforce exerted by the spring with the second spring rate.
- Dl and D2 mean the first and second spring rate and ALI and AL2 a deflection of the spring device under the influence of the magnetic force, in particular ALI meaning the deflection of the spring device until the desired intermediate position is reached .
- the closure body Only when a sufficiently high second force F2 is applied, in particular by applying a higher voltage or a corresponding pulse width modulation of the voltage. the closure body can be moved from the intermediate position into the fully open position.
- the higher second force is dimensioned such that it is sufficient to overcome the force exerted by the spring at the second spring rate.
- first spring and the second spring can be arranged coaxially and, in particular, can be formed as spiral springs arranged symmetrically about a longitudinal axis of the valve.
- the two Springs between the intermediate position and the fully open position be connected in parallel and the restoring forces exerted by them on the closure body add up.
- Such an arrangement has the advantage that it takes up little installation space.
- the two springs or several springs can also be connected in series.
- the second spring in particular can have a smaller diameter than the first spring, i.e. be arranged within the first spring.
- an inverted arrangement is also conceivable, in which the first spring has a smaller diameter than the second spring.
- the first spring is compressed when the electromagnetic actuator unit provides a first magnetic force.
- An intermediate position is reached when the closure body has moved axially so far that the stop comes into contact with the collar.
- the second spring begins to exert a counterforce on the collar and the stop on the closure body, which can only be overcome by a correspondingly increased magnetic force.
- the spring device can also have a single spring which is designed such that it can be compressed with different spring rates. For example, a spring with a progressive winding can be used.
- the spring device thus has a single spring which can be compressed with a first spring rate up to an intermediate position and then with a second spring rate, in particular the first spring rate being smaller than the second spring rate.
- the actuator unit can be actuated in order to exert either a first force Fl or a second force F2 on the armature, where Fl is not equal to F2.
- Figure 1 shows schematically a valve in a closed
- Figure 2 shows schematically the valve of Figure 1 in a partially open intermediate position
- Figure 3 shows schematically the valve of Figure 1 in a fully open position.
- FIG. 1 schematically shows a valve 1 designed as a diverter air valve for a turbocharger (not shown) of a vehicle in a closed position according to an embodiment of the invention.
- the valve 1 is shown in Figure 1 as in all figures in longitudinal section, i.e. cut parallel to a longitudinal axis of the valve.
- housing part 13 and the further Ge housing part 18 can also be formed in one piece with the housing 2.
- An electromagnetic actuator unit 5 with a coil 6 and a metallic pin 7 connected to an armature 8 is arranged in the housing 2.
- the pin 7 is by means of egg nes upper bearing 24 and a lower bearing 26 in the Ge housing 2 axially displaceably and firmly connected to a topfförmi gene closure body 10.
- the cup-shaped closure body 10 serving as a piston interacts with a valve seat 12 in order to block or release the bypass line 4.
- the closure body 10 has an annular sealing surface 14 which cooperates with a valve seat 16 in order to seal the cross section of the bypass line 4.
- a spring device 17 presses the closure body 10 in the direction of the valve seat 16. Against the force generated by the spring device 17 acts when not actuated Valve 1 only the force acting on the bottom 12 of the closure body 10 due to the pressure in the line 4.
- the spring device 17 has a first spring 32 and a second spring 34.
- the first spring 32 and the second spring 34 are coaxial with the first spring 32 and the second spring 34.
- the first spring 32 Has a diameter than the first spring 32 and is arranged within the first spring 32.
- the first spring 32 and the second spring 34 have spring rates D1 and D2, respectively.
- the second spring 34 is shorter than the first spring 32.
- the first spring 32 is supported at one end on the bottom 12 of the closure body 10 and at the other end on an annular disk 40 which is coaxial with the longitudinal axis L in the housing 2 is arranged.
- the second spring 34 is also supported at one end on the washer 40, but with its other end on a collar 30 which is held by a guide sleeve 28.
- the guide sleeve 28 is arranged concentrically to the pin 7 and the armature 8 in the housing 2 axially displaceable.
- the guide sleeve 28 is also relative to the pin 7 and the ker 8 axially displaceable. It has the task of holding the lower bearing 26 and also wearing the collar 30.
- the two springs 32, 34 together form the spring device 17.
- the spring device 17 has approximately two different spring rates in the embodiment shown. In a compression of the spring device 17 coming from the closed position of the valve 1 shown in Figure 1, the Federra te Dl of the first spring 32 is effective because initially only this spring 32 is compressed. If the valve 1 is opened further, however, the second spring 34 is simultaneously compressed from a defined intermediate position, so that the spring constant D1 + D2 becomes effective overall. This process is described in more detail with reference to FIGS. 2 and 3.
- Figure 2 shows the valve 1 according to Figure 1 in a partially opened position in which the bypass line 4 is partially released, i.e. a reduced mass flow through this is possible.
- a voltage was applied to the magnetic coil 6, which resulted in a magnetic force that was sufficient to compress the first spring 32.
- the valve 1 then opened until the stop 36 came to rest on the underside of the collar 30. This position is shown in Figure 2.
- bypass line 4 is only to be partially released, a voltage is therefore applied to the coil 6 which is sufficient to overcome the counterforce of the first spring 32 and to achieve the intermediate position shown in FIG. 2, which is too low to overcome the additional counterforce of the second spring 34 and the position shown in FIG. 3, fully open to reach.
- the valve 1 thus enables not only a fully closed and a fully open position, but also an intermediate position. If the spring device 17 is designed such that it has more than two different spring constants, further intermediate positions are also conceivable, between which the spring constant typically increases gradually.
- the electromagnetic actuator unit 5 is controlled accordingly in order to overcome the respective counterforce of the spring device 17. In this way it is possible, by means of an electromagnetic valve and dispensing with position sensors, to provide a diverter valve which has one or more defined and selectively controllable intermediate positions of the closure body 10.
