Abstract
977,260. Rotary pumps. THOMPSON RAMO WOOLDRIDGE Inc. Aug. 13, 1962, No. 30967/62. Heading F1F. A rotary pump of the sliding-rocking vane type comprises a chamber 16 (Fig. 1) of non- circular configuration housing a rotor 17 fixed to a drive shaft 21 and provided with notches 24 containing spring-biased outwardlysliding rockable vanes or slippers 28. Fluid, e.g. oil is drawn into chamber 16 through a passage 13 (Fig. 3) and an inlet port 31, a proportion of the fluid being discharged through an outlet port 34 whilst the remainder is discharged through a further outlet port 40. The radius of curvature of the peripheral wall of chamber 16 varies as shown in Fig. 1, whereby the volume of liquid between the rotor and this wall varies accordingly. Ports 31, 34, 40 are shaped to allow fluid to pass into and out of notches 24. A pressure-equalizing passage 46 provided with a non-return valve 47, 48 connects ports 34, 40. An outlet passage 39 communicating with port 40 also communicates with passage 13 through an orifice 43 to boost the flow of fluid to the pump when the rotor rotates at high speeds.
