Abstract

689,313. Rotary pumps. PLENTY & SON, Ltd., and BROWN, S. G. Sept. 11, 1950 [Sept. 9. 1949]. No. 23373/49. Class 110(ii) In a variable-delivery rotary pump the stator 16 is moved to vary its eccentricity relative to a rotor 12, by means of a piston 32 which is subjected to the pump delivery pressure on its upper surface and a constant pressure through a pipe 40 from a hydraulic accumulator, on its lower surface. The accumulator pressure may be adjusted by varying a number of weights 44, Fig. 1 (not shown).
