Title: ELECTROMAGNETIC PART FOR A HYDRAULIC VALVE AND HYDRAULIC VALVE
Abstract:
The invention relates to an electromagnetic part (14), having a magnetizable housing (16), which extends around a solenoid (22) at least at an outer periphery (50) at least in some regions, and having a pole tube (20), which is arranged within the solenoid (22) and in which an armature (26) is provided in an axially movable manner in an armature chamber (56). A sliding structure (40) is arranged between an inner surface (48) of the pole tube (20) and a radially outer surface (49) of the armature (26), which sliding structure (40) has a plurality of cut-outs (60), which are distributed in a planar manner on a surface (64) facing the armature (26). The invention further relates to a hydraulic valve (10), having an electromagnetic part (14) and a hydraulic part (12), wherein the electromagnetic part (14) has a sliding structure (40) having cut-outs (60) distributed in a planar manner.
