Abstract

1322891 Hydraulic reciprocating pumps or motors SELF-CHANGING GEARS Ltd 21 July 1970 [12 May 1969] 24114/69 Heading F1A A radial cylinder pump or motor comprises a fixed or rotatable cylinder block 1 disposed between a central valve sleeve 22 and a surrounding multi-lobed cam ring 14, the block 1 having rectangular cylinders each of which receives a roller piston 9 which engages the cam ring. The cylinder block shown, rotates, and has its cylinders arranged in four axially spaced planes. During rotation each cylinder registers with each of a plurality of alternate, circumferentially spaced inlet and outlet ports, 25, 26, 27, 28 in the fixed sleeve 22. The inlet and outlet ports are connected to supply and exhaust, respectively, through longitudinal slots 36, 37 cut in the periphery of a pintle 23 slidable within the sleeve 22. By displacing the pintle 23 to any of positions 41, 42, 43, the number of cylinders operative may be reduced. The cylinders in adjacent planes may be staggered, Fig.3 (not shown).
