Abstract

An actuating device, particularly for actuating valves connected externally, includes a housing (10) and a coil body (12) arranged in the housing. The coil body has a coil winding (14) at least partially enclosing a coil tube (16), a pole core (20) connected at the coil tube free end, an armature (22) guided in a longitudinally displaceable manner at least in the pole tube (16) within an armature chamber (24) and interacting with an actuating part (26) for actuating the respective valve part. The pole tube (16) is designed as a receiving sleeve for the armature (22). The sleeve is fixed with its free end region to a fixed bearing point. The fixed bearing point is formed by two support parts (118, 124) of the pole core (20) that delimit a receiving gap between them, in which the free end region of the receiving sleeve is fixed in a clamped manner.
