Abstract

791,972. Rotary pumps. THOMPSON PRODUCTS, Inc. Oct. 26,1955, No. 30687/55. Class 110 (2). A gear pump has a middle housing member 11b of bronze or the like and end members 11a, 11c of aluminium or the like, bores 20, 21 in the bronze member 11b forming bearings for the ends 24a, 25a of hollow shafts of gears 22, 23. The ends 24b, 25b of the shafts are journalled in movable end-plates B, each of which has a cylindrical flange 43, Fig. 6, flattened at 49, concentric with a tubular part 46 with an eccentric cylindrical shoulder 48 formed on the back surface of the flange 43. Delivery pressure is admitted through a passage 50 to the space P to act on the eccentric surfaces 44 which are disposed so that a larger area lies opposite the delivery side than opposite the inlet side. Sealing rings 36, 51 of figure-eight configuration seal the space P. The end-plates B are initially loaded by springs 54. Fluid under inlet pressure communicates through the hollow shafts with spaces 38, 39 at the ends of the parts 46 of the end-plates B which also communicate through a passage 58 with a relief valve 10. Lubricating grooves 56, 57 are formed in the shafts journals.
