Abstract

1,032,578. Fluid pressure brakes. CLAYTON DEWANDRE CO. Ltd. March 5, 1965 [March 5, 1964], No. 9358/64. Heading F2F. In a compressed air vehicle braking system comprising an automatically-operating antiskid device (not shown) which, on sensing wheellocking, energizes a solenoid 16 to operate a valve element 8, initial displacement of the said element interrupts supply of compressed air to a two-chamber brake cylinder whilst further movement of said element interconnects opposite sides of the diaphragm 4 or piston of the cylinder to destroy the pressure differential across the diaphragm or piston to effect brake release. During normal brake operation, the spool-like valve element 8 is urged by spring 21 to the top of its housing 7 which is bolted to a double-chamber brake cylinder formed by a diaphragm 4 clamped between dished plates 1 and 2 by a ring 3. Compressed air is fed from a source (not shown) by a driver's valve (not shown) through an inlet port 9, past the waisted portion 8b of the spool, through outlet port 10 to the chamber on the left-hand side of the diaphragm. In addition, the chamber on the righthand side of the diaphragm is vented to atmosphere through line 12, port 11 and exhaust 13. Consequently, thrust rod 6 is moved to the right to apply the brake. On wheel-lock being sensed, the anti-skid device energizes solenoid 16 which actuates a pilot valve 17. This valve connects a port 20, normally vented through opening 18, to a further compressed air inlet 19. The valve element 8 is displaced downwards to the position shown to initially cut-off the connections between ports 9 and 10 and ports 11 and 13, respectively. Further downwards movement of the valve element then interconnects ports 10 and 11 to equalize the pressure across the diaphragm and destroy the braking force. The arrangement is said to conserve the compressed air supply and ensure rapid re-application of the brake, if necessary, by the residual pressure remaining in the chamber on the left-hand side of the diaphragm.
