Abstract

1512382 Anti-skid braking systems AUTOMOTIVE PRODUCTS Ltd 29 April 1975 [30 Jan 1974] 04298/74 Heading F2F The subject matter of this application is substantially the same as that of Specification 1,512,384 but the claims are directed to a brake pressure modulating device in or for a braking system and comprising two parallel variable volume chambers between respective inlet ports 29, 30 and outlet ports 31, (32) with movable walls 79, 80 controlled by a common piston 44 subject to a resilient force of a spring 46 which is less than the fluid pressure in both chambers but more than the fluid pressure in one chamber during braking so that on failure in one braking circuit the device does not reduce the pressure in the other circuit.
