Abstract

1,116,051. Fluid-pressure brakes; valves. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINENUND ARMATURENFABRIK KOMM. GES.]. 24 March, 1966 [15 Sept., 1965], No. 13037/66. Headings F2F and F2V. In a valve assembly for insertion in the line between the master cylinder and the front wheel disc brake cylinders to delay the application of the front wheel disc brakes, a piston 10 is disposed in a cylindrical chamber 3 and is loaded on one side by a spring 11 such that it can move against the force of the spring as far as an annular stop formed by a plug member 12, on the other side of the piston there is a push rod 13 which is associated with and guided by a ball valve arrangement 14-18 controlling the flow of brake fluid from the master cylinder to the wheel brake cylinder to keep the valve open when the brake is off. The ball valve comprises a spring-loaded ball 15, a valve seat 14 formed with projections 14a and guided in a chamber 4 of larger diameter than the chamber 3 and an annular disc 17 is disposed on a shoulder 13a of the piston push rod 13, the push rod passing through a slotted bush 16 which is forced by a weaker spring 18 against the valve seat 14. When the brake is in its operative position the parts of the valve are in the position shown in Fig. 1 wherein the push rod 13 of the piston 10 keeps the ball 15 of the ball valve in its open position so that there is unpressurized connection between the master cylinder and the wheel brake cylinder. When the brake is applied, the master cylinder supplies brake fluid to the wheel brake cylinders via a port 6, open ball valve 15, and apertures in the slotted bush 16 to the front wheel brake cylinders via connection 7. As the brake back pressure builds up, the piston 10 is moved against its spring 11 and the ball valve closes to prevent further flow to the front wheel brake cylinders. When the pressure of the brake fluid supplied by the master cylinder to chamber 4 rises further the valve seat 14 with the ball 15 disengages from its seat and moves against the force of the spring 18, brake fluid being then able to flow via the projections 14a and slotted bush 16 to the front wheel brake cylinders so that the brakes are applied with delay.
