Abstract

1383812 Rotary positive-displacement machines CENTRUM TECHNIKI OKRETOWEJ PRZEDSIEBIORSTWO PANSTWOWE WYODREBNIONE 22 Feb 1972 [22 Feb 1971 5 July 1971 20 Nov 1971] 8067/72 Heading F1F A double-acting pump, or motor, has a rotor 2 with spring-loaded pivoted vanes 3 engaging with an elliptic cam-surface 8 on a cylinder 5 that can be turned with aid of a lever 19 and toothed wheel 17 to vary the output or effect reversal. Inlet and outlet ports 13, 14 communicate with corresponding chambers 11, 12 on the inner sides of end covers 7 fixed to the housing 1. Each vane abuts a seal 10 fixed to the rotor and has sealing plates that slide on the surface 8, Fig. 7 (not shown). The vanes may be replaced by part-cylindrical vanes lodged in similarly shaped channels formed in the rotor, Figs. 8 to 11 and 12 to 15 (not shown). In another embodiment, Figs. 3 and 4 (not shown) the cam surface is on the housing, the cylinder being omitted, and the output is varied by turning a pair of rings that abut the sides of the rotor and contain chambers similar to and replacing the chambers 11,12. In a further embodiment, Fig. 5, the cylinder 5 is replaced with a cylinder 34 having diametrally-opposed pairs of pistons 35, 36 and flexible and resilient walls therebetween so that its shape can be varied to change the output or effect reversal. The pistons are controlled hydraulically through openings 40. Inlet and outlet chambers 45 communicate with ports 44 in the cylinder.
