Abstract

174,255. Lindsay, W. Nov. 18,1920. Multiple-way valves; closure members, rotary conical.-Working valves for hydraulic machinery comprise a block H having a passage H' connected to the service pipe and passages H<2> connected to the operating and return cylinders of an hydraulic press or to opposite ends of an hydraulic cylinder. A rotary valve plug has a longitudinal passage N<4> communicating with two radial passages N<5> for controlling entry of water into the passages H<2> and radial passages N<7>, N' for controlling exit of water from the passages H<2> to an exhaust pipe. The plug is of generally tapered form with parallel sided portions with recesses for the reception of packing N<1>, N<2>, N<3>, and a ball race P is provided between the plug shoulder and the gland 0. The operating lever L works over a quadrant having end stops and pin holes for securing the lever in various positions.
