Abstract

1304491 Fluid pressure brakes; valves J GACHOT and F PERALES 9 Sept 1971 [9 Sept 1970 22 July 1971] 42190/71 Addition to 1217626 Headings F2F and F2V In an improvement in or modification of the compressed-air brake system of Specification 1,217,626 the body 71 of the double check valve A is composed of a single piece and comprises an inner chamber 72 bounded by two smooth opposite walls 73 in which the air inlet ports 52, 55 discharge, the valve flap 76 having projecting from each face an annular beading 81 of resilient material which seals against the wall around the port when the flap is in obturating position. In a modification at least one of the faces has at least two beadings of different diameters.
