Abstract
An electromagnetic drive unit, particularly for valve slides of solenoid valves, includes a magnetically conductive housing which is connectable to a gas generator for airbags and a coil body provided with an exciting coil mounted in the housing, and a displaceable armature pretensioned by a spring and connected to the valve slide. The coil body with the exciting coil is closed off toward the open side of the housing by a correspondingly shaped metal cover. The cover is provided with a central hollow cylinderical portion which is surrounded with play by a cup-shaped member. The cup-shaped member guides the valve slide which is supported by the armature.
