ABSTRACT:
A fluid pressure control valve suitable for a pressure intensifying valve of an automotive anti-skid brake control system comprises a valve housing, a solenoid attached to the valve housing, a plunger slidably enclosed in the valve housing and having a main valve portion at one end thereof to close the valve in response to energizing of the solenoid, and a return spring disposed in the housing for biasing the plunger in a valve opening direction. The pressure control valve includes a dashpot like device arranged at the other end of the plunger, for dampening a motion of the plunger in a valve opening direction.
