Abstract
135,799. Shaw, H. S. Hele-. April 12, 1918. Clutches and speed-varying mechanism. - In hydraulic clutches of the kind wherein pistons cooperate with one or more cams, means are provided for freeing the pistons from contact with the cams when the clutch is thrown out. The invention is described with reference to the clutch described in Specification 135,524, in which the driving-shaft 1 carries a body 3 provided with cylinders 5 communicating with a closed circuit comprising passages 10, 10<a>, valves 11 controlling the circulation of liquid, and the pistons 7 coacting with swash-plates 8 keyed to the driven shaft 9. The closed circuit is kept full by liquid supplied through a running joint 18, pipes 16, and non-return valves 17. The valves 11 are moved from their open positions against the action of springs 20 by pressure liquid from a cock 22 passing through the joint 18, pipes 21, and ports 23. When the cluch is to be thrown out, the cock 22 is operated to relieve the pressure, the springs 20 open the valves, and liquid in the closed circuit passes out through passages 25, thus allowing springs 14 to move rings 12 towards each other and free them from the swash-plates.
