Abstract
A clutch and brake assembly which includes a spring applied brake and a fluid applied clutch which is adapted to rapidly cycle. A fluid circuit is provided for rapidly pressurizing and rapidly depressurizing the apparatus. The fluid circuit includes a manifold having a main fluid passageway and a plurality of secondary fluid passageways disposed therein. Each of the secondary fluid passageways includes a quick release exhaust valve which is operable to rapidly exhaust fluid from the apparatus to allow the brake to rapidly engage when the fluid pressure in the main fluid passage way and secondary passageway decreases to less than the fluid pressure in the pressure chamber.
