Abstract
A pressure boosting device as used in a vehicle brake system or other hydraulically operated system wherein the boosting device is connected to a mechanically operated pressure regulator for producing a manually controlled pressure, an electrically controlled pressure regulator and a hydraulically operated actuator, and includes a booster piston for boosting an electrically controlled pressure produced by the electrically controlled pressure regulator so that the boosted pressure is applied to the actuator, and a valve mechanism having an open and a closed position which are established when the booster piston is placed in its original position and moved away from the original position, respectively. In the open position, the actuator communicates with the mechanically operated pressure regulator. In the closed position, the actuator is disconnected from the mechanically operated pressure regulator, to permit the booster piston to boost the electrically controlled pressure.
