Abstract

171,174. Stone & Co., Ltd., J., and Davis, S. L. B. Aug. 10, 1920. Liquid-pressure engines.-In radial, revolving- cylinder pumps and motors having eccentric driving gear, and wherein the liquid is distributed by a stationary valve about which the cylinder rotor revolves, such as described in Specification 169,013, the valve consists of a ported-disc, ring, or sleeve member which is locked in position on the central shaft with its ports registering with passages therein. The valve, Figs. 1 and 2, comprises a ring c with projections v, v<1> keyed to the shaft b and with ports 1, 2 communicating with passages j, j<1>, k, k<1>, t, t<1>. In the case of a pump, the passages t, t<1> constitute the delivery and suction respectively; in the case of a motor, the exhaust and admission. The shaft b has a flat-sided collar n which is held by screws in a boss o on the casing. In a modification of the valve, a ported conical sleeve is secured to the shaft and is mounted in a recess in the rotor e. In the construction shown in Figs. 6 and 10, the shaft is reduced at b' and has a series of longitudinal passages j', k'. The valve sleeve 12 has tapered ports 17, and is held stationary by dowels 19. The cylinder ports and ends of the shaft passages are inclined.
