Electromagnetic control device for use as electromagnetically operated pneumatic or hydraulic valve, has armature unit non-detachably connected with stationary magnetically retaining ring with valve closing element over spring element

摘要

The device has a valve closing element e.g. seal (18), guided as actuatable by an armature unit (16) e.g. ring-or disk-shaped flat armature, axially movable relative to a stationary coil device provided in housing liner (26). The armature unit is non-detachably connected with a stationary magnetically retaining ring (22) with the fitted and/or partially enclosed closing element over a spring element that is formed as a flat-, sheet-, plate or diaphragm spring. The ring in a radial direction encloses the armature unit in sections.
