Abstract

695,743. Rotary pumps. BORG-WARNER CORPORATION. May 11, 1951 [May 19, 1950], No. 11135/51. Class, 110(ii) A pump with pressure-loaded end bushes at one end, provided for sealing purposes, has two surfaces, one loaded with the inlet pressure and one with the discharge pressure. The bushing assembly is designed to fit an existing pump without modification of the pump being necessary. The figures show a gear pump with gears 9, 10 integrally formed with hollow shafts 11, 12 supported in normal bushes 13, 14 at one end. Axially-adjustable bush-assemblies 15, 16 each comprise a barrel 22 and a cover 23 having areas 26, 25. Inlet pressure is applied over an eccentric area at the base of 25, against a portion of the cover 23, using a radial groove 23a and an aperture 24. Discharge pressure acts against a surface 26, plus the force of initial-loading springs 37, using an axial passage 38 leading from the delivery port 19: A seal 35 separates the two pressure chambers. Lubrication of the shaft is provided by an axial groove 28 and spiral grooves 29. A groove 30, in the bush 22, is cut deeply to reduce the weight and expose a greater area of the bush to the fluid being pumped, for cooling purposes. A bevelled area 39 may be provided around part of the periphery of the forward face of the cover 23 adjacent the outlet 19, allowing limited communication between the inlet and discharge ports. Figs. 4 and 5 show a modified arrangement with the bush 52 and cover 41 stepped to form two recesses 44, 45, of unequal size, the recess 44 being offset to the left and 45 centred with respect to the bushing. Inlet pressure fluid passes into the recess 44 by way of a hole 60 in the cover 41. Discharge pressure acts against an area 46, a seal 55 being provided between the two chambers. By increasing or decreasing the size of recess 45, the extent of compensation for high inlet pressure may be controlled. The area 45 is in communication with the lubrication ducts 43, 49. The invention may be applied to vane pumps. Specification 695,752 is referred to.
