The invention relates to an actuating device, particularly for actuating valves that can be connected externally, comprising a housing (10) and a coil body (12) arranged therein and having a coil winding (14), which at least partially encloses a coil tube (16), having a pole core (20) connected at the free end thereof, further comprising an armature (22) that is guided in a longitudinally displaceable manner at least in the pole tube (16) within an armature chamber (24) and interacts with an actuating pan (26) for actuating the respective valve part, wherein the pole tube (16) is designed as a receiving sleeve for the armature (22), said sleeve being fixed with the free end region thereof to a fixed bearing point, and wherein 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.
An actuating device, in particular for actuating valves that can be connected externally, comprising a housing (10) and a coil body (12) arranged therein and having a coil winding (14), where said coil body encloses at least in part a pole tube (16) to whose one free end a pole core (20) is connected, with an armature (22) which is guided to be longitudinally displaceable at least in the pole tube (16) within an armature space (24), and which interacts with an actuating part (26) for actuating the respective valve part, the pole tube (16) being designed as a receiving sleeve for the armature (22), said receiving sleeve being fixed with its free end region at a fixed bearing point, characterized in that the fixed bearing point is formed from two support parts (118, 124) of the pole core (20) which delimit a receiving gap between them, in which the free end region of the receiving sleeve is fixed by clamping.
