Electromagnetic actuator for controlling gas changeover valve in IC engine

摘要

The actuator has an armature between separate switching magnets oscillating against the force of valve restoring springs. The armature has a drive connection to the valve (2) shaft via a guide pin. A bush (13) is arranged with axial movement in a guide device (12) associated with the opening switching magnet (5) between the guide pin and valve shaft. The bush accommodates a hydraulic valve play compensation element (11) and is also part of a locking arrangement (14) that is controlled to act in the valve closed position.
