Abstract

1,152,188. Rotary positive-displacement pumps and motors. T. KUHARA. Sept. 15, 1966, No.41266/66. Heading F1F. A rotary positive-displacement pump, or motor, of the externally-meshing gear-type comprises a pair of gear-wheels, or gears, 4,13 fixed to a driving, or power-output, shaft 1 and rotatively mounted on a non-rotatable shaft 12, respectively, the latter being supported by a spring-loaded piston 11 and a piston 14 to which fluid-pressure can be applied through a passage 6 so as to seal the gear-tooth spaces of the gear 13 and move this gear relative to the gear 4, thereby varying the output of the pump or motor. The effective areas of the inner ends of passageways 15,17 for the working fluid e.g. oil, are regulated by the piston 11 in accordance with the effective axial length of the gear 13, a rod 8 being attached to said piston to permit manual control thereof. A screw-threaded sleeve 9 facilitates adjustment of the spring-loading of the piston 11. The passage 6 may be connected to the highpressure side of the gears. When operating as a motor, oil may be supplied thereto by a pump (25, Fig. 8A, not shown) which is driven by a prime mover (26), the oil being passed through a cooler (24) containing a filter and controlled by valves (21, 22, 23). When operating as a pump it may be used to supply oil to a motor (29, Fig. 8(B), not shown), the arrangement being generally similar to that according to Fig. 8(A).
