<p>An inertia-controlled valve assembly includes a valve seat provided within a valve chamber and a ball disposed within the valve chamber to co-operate with the valve seat and rolling toward the valve seat on the inclined bottom surface of the chamber of which the inclination is varied in accordance with the rate of deceleration of the vehicle. In the inertia-controlled valve assembly, a movable element is slidably disposed within the valve chamber to subdivide the valve chamber into a first chamber receiving the ball therein and a second chamber in communication with an inlet port and provided thereon with an orifice to permit fluid communication between the first and second chambers, whereby in rapid operation of the master cylinder the movable element is moved toward the valve seat by a pressure difference produced between the first and second chambers due to the orifice so that the ball is forcibly moved toward the valve seat to close the valve.</p> |
