Abstract (en)

[origin: DE19745522A1] The device has an electromagnetic actuator with a tubular armature spindle (17) with load orientated areas (31-33) with different wall thicknesses. The armature spindle has a thread (21) on the end furthest from the two solenoids (9,10). A clearance compensation element (29) is connected through the hollow spindle to a pressure connection (30). To form a supply chamber (34) for pressure medium the hollow armature spindle is sealed and is connected to the pressure connection via a hole (41).
