초록 ▼

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.

대표청구항 ▼

A pressure boosting device provided in a hydraulically operated system wherein the pressure boosting device is connected to a mechanically operated pressure control device, an electrically controlled pressure control device and a hydraulically operated actuator, said mechanically operated pressure control device producing a manually controlled hydraulic pressure whose level is regulated depending upon an operating force acting on the mechanically operated pressure control device, while said electrically controlled pressure control device producing an electrically controlled hydraulic pressure whose level is electrically regulated, said pressure boosting device comprises: a stepped booster piston for boosting said electrically controlled hydraulic pressure produced by said electrically controlled pressure control device, so that the boosted electrically controlled hydraulic pressure is applied to said hydraulically operated actuator; and a valve mechanism operated according to a movement of said booster piston, said valve mechanism having an open position in which said actuator communicates with said mechanically operated pressure control device, and a closed position in which said actuator is disconnected from said mechanically operated pressure control device and in which said booster piston is permitted to boost said electrically controlled hydraulic pressure, said valve mechanism being placed in said open position when said booster piston is placed in an original position thereof, and in said closed position when said booster piston is moved from said original position.
