Abstract

1,114,095. Axial piston pumps and motors. UNIPATA.G. Jan. 20, 1967 [Jan.22, 1966], No. 2998/66. Heading F1A. In an axial opposed piston pump or motor the cylinders are formed by separate sleeves 23 located in bores in the rotor 17,18,19. The sleeves are located by spring biased members 54 in the rotor part 19. The face valve 38 is supported by pipes (33, 34, 35, 36), Fig. 3 (not shown), located in fixed end plate 11 and a spigot 42 engaging a recess in the rotor part 19. In a further embodiment, Fig. 4 (not shown), a pintle valve (60) is mounted in a recess in the intermediate part (61) of the rotor. Radial balancing of the pintle (60) is provided by arcuate grooves (66, 67) in its external surface which are connected to the inlet and outlet of the pintle valve. The cam members 12,13 may be fixed or one or both may be angularly adjustable.
