| Zusammenfassung: | The invention provides a solenoid actuated valve with a plunger which moves in a sleeve under influence of a magnetic field from the solenoid and further comprising a damping device for reducing noise and wear caused by the plunger when it bounces against a top part located in the sleeve. The damping device comprises a first part which forms the limit of the travel of the plunger and another part which is allowed to move relative to the first part in a dampened movement. To enable application in a vacuum system, the damping device comprises a conduit which allows evacuation of a chamber confined between one end of the sleeve and the damping device. The invention further provides a damper for a solenoid actuated valve. |
