Abstract
A pressure control valve has a substantially closed housing, an armature provided with an integrated valve body, a valve seat with which the valve body cooperates, a spring acting on the valve body so that the valve body cooperates with the valve seat, an electromagnet arranged to adjust a control pressure. The magnet armature is somewhat bucket-shaped. A projection extends in an interior of the housing and operates for guiding a magnetic flux. The magnet armature surrounds the projection and is mounted on the valve body in a friction-transmitting manner. A second spring acts on the valve body so as to counteract an action of the first mentioned spring.
