<p>A pressure control valve with an impact plate which serves as a regulator for a specific drop in pressure. The pressure control valve includes an armature disposed in an electromagnetic field established by an electromagnetic coil and a permanent magnetic field, with the armature being rotatably supported between two respective pole shoes located on each side of the armature. The pole shoes located on one side of the armature, in contrast to the pole shoes located on the other side, have an opposing magnetic polarity induced by the permanent magnet. The pole shoes which are not aligned opposite one another on armature 85, are approached by armature 85 with movement of the impact plate toward a valve seat, and causes an increase in the air gap planes facing the armature, as compared to the other two pole shoes, and thereby establishes a non-linear characteristic for the pressure control valve.</p> |
