초록

A solenoid for a hydraulic valve has an armature chamber having chamber walls. A pole core forms one of the chamber walls and has an axial central bore. An armature is slidably arranged in the armature chamber. The armature has a central receptacle. An armature piston is arranged in the central receptacle of the armature and extends through the axial central bore of the pole core. The armature piston consists of a nonmagnetic material. The armature piston acts on a valve member when moved by the armature piston. The armature piston is a tubular member fo...
