Abstract
A deceleration detecting valve for use in a vehicle hydraulic braking system having a master cylinder, a first circuit connecting the master cylinder with front wheel brakes and a second circuit connecting the master cylinder with rear wheel brakes. The valve has a chamber, and a gravity ball received in the chamber and movable from a first position to a second position in receiving a predetermined deceleration thereby restricting the pressure acting on rear wheel brakes. A slidable member is provided in the chamber with one end thereof receiving the pressure in the first circuit, and ball guiding surfaces are defined on the wall of the chamber and on the slidable member. When the first circuit fails the slidable member retracts in the chamber, and a gap is formed between the ball guiding surface on the slidable member and that of the wall of the chamber thereby impeding the movement of the ball.
