Abstract

An actuating device, particularly for actuating valves that can be connected externally, includes a housing (10) and a coiled body (12) in the housing and having a coil winding (14). The winding encloses a pole tube (16) at least partially, having a pole core (20) connected at its free end. An armature (22) is guided in a longitudinally displaceable manner at least in the pole tube (16) within an armature chamber (24) and interacts with an actuating device (26) for actuating a valve part. The actuating part (26) is guided within the pole core (20) along an annular body (92), sealing the inside of the pole core (20) and the pole tube (16) relative to the surrounding area.
