Abstract
690,902. Gear pumps. BORG-WARNER CORPORATION. June 1, 1951 [June 16, 1950], No. 13051/51. Class 110(ii) The pump has pressure-loaded end bushes 13, 15 provided with offset recesses 40, in the bushes facing gears 8, 9, the recesses being vented to a space of lower than the discharge pressure. The larger area of each recess is on the side nearer the discharge port 17. The outer edge of a recess is of less radius than the minimum radius of the tooth spaces. Passages 42 lead to end chambers 33, ducts 38 and to the inlet side 16 of the pump. Fig. 4 shows a modification in which each recess 46 is part'annular with a vent 47 leading to the pump inlet. The external bush area under discharge pressure may be eccentric 51, as shown, to give a larger pressure opposite the discharge side of the pumping chamber than that opposite the inlet side. A coupling 21 for shafts 27, 10a, comprises splines 26, 20 and a spring 28 bearing against the coupling to effect a seal by means of a ring 23 and packing 24. Hollows in the gear shafts allow pressure balancing to be secured at the shaft ends.
