DEVICE FOR TRANSMITTING A DISPLACEMENT OF AN ACTUATOR WITH AN ELASTOMER RING

摘要

The device for the transmission of the excursion of a solenoid, especially for an injection valve, has a first (6) and second (7) piston which are in interacting communication by fluid through at least one transmission chamber (10) which is hydraulically connected to a compensating chamber via a sealing gap which provides compensation for pressure differences between the transmission chamber and compensating chamber with a time delay. The compensating chamber (22) is bounded by an elastomer ring (50) which is connected to and sealed relative to the housing (5) of the device and to one of the pistons.
