Abstract
681,513. Rotary pump; stuffing-boxes. BORGWARNER CORPORATION. Nov. 6 1950 [Dec. 3, 1949], No. 27042/50. Classes 110(ii) and 122(v) In a liquid pump of the type described in Specification 572,967 with end bushes subjected to pump delivery pressure on the outside, the areas under pressure have axes eccentric to the rotor axes so that a greater load acts opposite to the delivery side of the pumping chamber, than opposite the inlet side. As shown, a gear pump has bushes 13, 15 under pump, delivery pressure externally, the bushes being eccentic to each gear axis so that an area 13a is opposite the pump chamber near its delivery port 19, and an area 13b opposite to the inlet port 18. A duct 30 leads pressure fluid to the bush surfaces. Light springs 31 give an initial load to each bush. The areas 13a, 13b may be other than circular. The upper gear 10 is driven by a shaft 27 through a sleeve 21 having internal splines 26, 20, the sleeve being pressed to the left by a spring 28. A bearing ring 23 co-acts with a packing ring 24. The invention may be applied to vane pumps.
