Definitions
- the invention relates to a Combined electromagnetic / pneumatic actuator for controlling a Lift valve, in particular gas exchange valve of an internal combustion engine, in which a Anchor connected to a stem of the lift valve in the drive connection Stroke-spaced switching magnets against diametrically acting pneumatic Springs controlled oscillating is arranged, further comprising one with the shaft Piston connected to the drive, a chamber assigned to the actuator in diametrical Air spring compartments divided for filling and emptying by means of electromagnetic valves are controlled.
- a similar actuator is known for example from EP-A 0 328 192. Further an actuator is known from US-A 5 611 303, the upper, rigidly arranged Closing switching magnet a lower, movably arranged in the axial direction Opening solenoid is assigned to achieve a variable valve lift. The closing magnet is adjusted hydraulically, so that this actuator different fluids to achieve pneumatic springs on the one hand and hydraulic valve lift adjustment are required on the other hand.
- the invention has for its object to provide a generic actuator variable valve lift adjustment with less effort to set up.
- the advantage of the invention is that the selection is particularly agile or fast-working Valves to see, so that in a further advantageous manner on the pneumatic Springs the desired valve lift adjustment can be controlled, as in Another embodiment of the invention is proposed in claim 2.
- the chamber side Mouths of the pneumatic control lines in the respective stroke end area of the armature serving as a piston to achieve pneumatic stops in each case are controlled by the armature or piston.
- This is advantageously between the armature and the respective switching magnet generates an air cushion that prevents the armature from striking the respective magnet and thus prevents it from moving acoustically advantageous quietly working actuator is achieved.
- a combined electromagnetic / pneumatic actuator 1 is used for control of a lift valve 2 of an internal combustion engine 3, which is only indicated
- Actuator 1 is a drive connection with a shaft 2 'of the lift valve 2 standing armature 4 between shift solenoids 5 and 5 'against diametrically acting pneumatic springs 6 and 7 controlled oscillating arranged.
- this actuator 1 has a drive-connected connection to the shaft 2 ' Piston 8, which also serves as an armature 4 and one assigned to the actuator 1 Chamber 9 divided into diametrical spaces 10, 11 for the air springs 6, 7.
- the air springs 6, 7 are for filling and emptying by means of solenoid valves 12 and 13 controlled.
- the solenoid valves 12 and 13 are according to the invention formed as an electromagnetically controlled coaxial valves 14 and 15. Both coaxial valves 14 and 15 are each via the connection 22 with compressed air provided.
- the pneumatic Closing spring 7 in space 11 of chamber 9 relaxes via lines 20, 17 and 16, whereas the pneumatic opening spring 6 in the space 10 of the air chamber 9 by supplying compressed air via the coaxial valve 15 and the line 21 with compressed air is applied.
- the actuator 1 is further designed such that the chamber side Mouths 18, 19 of the pneumatic control lines 20 and 21 in respective stroke end area of the piston-like armature 4 to achieve the pneumatic Attacks are additionally controlled by the armature 4.
- the anchor 4 can also be designed as a double cone advantageously better coordination of the switching magnets 5 and 5 'on the one hand and the electromagnetic coaxial valves 14 and 15 on the other hand for a sensitive responsive Stroke adjustment of the lift valve 2.
