Abstract

1468564 Aritiskid braking systems KELSEYHAYES CO 12 Aug 1974 [24 Aug 1973] 35480/74 Heading F2F An antiskid braking system includes fail safe means 84 comprising a member in the form of a plunger 96 movable from a normal position to a fail safe position in response to a malfunction in the skid control means for providing unrelieved brake actuating pressure and an indicator responsive to the said movement to provide a signal of malfunction to the vehicle operator. Pressure fluid is supplied to the rear brakes of a vehicle via a modulator 19 responsive to an electrical control module 26, the modulator causing a valve 29 to close and isolate the wheel cylinders from the master cylinder supply conduit 14 while an expansion chamber plunger 37 is permitted to regress against the bias of a power piston 42 to relieve braking pressure. If the power steering pump 49 providing a source of ancillary fluid fails or there is leakage from conduits 53, 59 or 56 the device 84 operates and includes a valve 85 normally held open by the plunger 96 which is connected to a piston 102 exposed to pump pressure and to the action of springs 92, 105 so that pressure failure causes the plunger to be moved by the springs. Valve 85 is closed and a by-pass 87 opened to allow fluid to flow to the wheel cylinders 17, 18 from the master cylinder and a visual warning provided by a lamp.
