Actuating device

摘要

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.

1. An actuating device for actuating an externally connected valve, comprising:
a housing; a coil body in said housing, said coil body having a coil winding and enclosing a pole tube at least partially, said pole tube being formed as a receiving sleeve fixed at a free end region thereof at a fixed bearing point; a pole core connected to said free end region of said pole tube and having first and second support parts forming said fixed bearing point, delimiting a gap therebetween and clampingly fixing said free end region therein, said first support part including a constriction site of said pole core having a smaller diameter than a remaining outside diameter of said pole core in a region of said fixed bearing point, a step-shaped transition region resulting from said constriction site forming a caulk surface as said second support part; and an armature guided for longitudinal displacement at least in said receiving sleeve within an armature space therein and interacting with an actuating part for actuating a respective valve part.
