Hydraulic valve, in particular an adjustable pressure control valve

摘要

The hydraulic valve has an electromagnet (10) with a coil (33) and a movable magnetic armature (40) connected to an armature pin (42) passing through a central bore of a pole shoe (34). A hydraulic part has a valve housing axially in contact with the pole shoe, an axial valve bore connected to a low pressure region, a fluid chamber with open fluidic connections to an armature chamber and low pressure regions. The fluidic connection between the fluid chamber (44, 56) and low pressure region (T) is outside a radial bore (27) in a fluidic connection between the valve bore (13) and low pressure region.
