Abstract

1,149,894. Radial piston pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept.12, 1966 [July 13, 19651, No.29607/65. Heading F1A. In a radial piston pump the track ring 17 is movable against the bias of a spring 18, to reduce its eccentricity relative to the rotor 13, under the influence of the pressure in the pump cylinders acting on the pistons 15. The pin 21 acts as a fulcrum for the ring 17. Liquid enters and leaves the cylinders through respective ports 19 which communicate with inlet and outlet ports in a pump cover (11, Fig.2 not shown). In a further embodiment, Figs. 3 and 4 (not shown), the maximum eccentricity of the track ring (25) is determined by a screw (33), shims (34) being inserted between the screw head and the pump casing (22) as desired. The pump body is provided with a central inlet (27) on one side of the rotor (23) and an outlet port (30) on the other side of the rotor.
