ABSTRACT:
A fluid pressure control device comprises an inertia-controlled valve for interrupting the flow of fluid from a master cylinder to rear wheel brake cylinders when a ball is subjected to a deceleration in excess of a predetermined value. In the control device, a bypass passage is provided to permit direct fluid flow from a valve chamber into an outlet chamber, the valve chamber being in communication with an inlet chamber and containing the ball therein, and a check valve is disposed within the bypass passage to normally interrupt the direct flow of fluid from the valve chamber to the outlet chamber, the check valve being opened to cause the direct flow of fluid from the valve chamber to the outlet chamber when a pressure difference is produced between the valve chamber and the outlet chamber after the inertia-controlled valve is closed.
