Fluid pressure actuated brake anti-lock control and method

Abstract From the Canadian patent

A braking arrangement and method for a rotating member, and particularly for a wheeled automotive vehicle which has a motive means for driving the vehicle, in which a fluid pressure actuated brake is provided for slowing the rotating member and a sensor signals the occurrence of an excessive rate of retardation of the brake member. Upon signalling of such an occurrence pressurized hydraulic fluid circulating through a system which includes a pump driven by the vehicle motive means is, blocked from flow from an actuating cylinder. Upon blocking flow of pressurized fluid from a cylinder through which the circulating fluid normally flows, a piston within the cylinder is moved to actuate an …
