Abstract

943,529. Joint-making packing; stuffing-box substitutes. THOMPSON RAMO WOOLDRIDGE Inc. July 2, 1962, No. 25289/62. Heading F2B. [Also in Division F1] In a fluid-pressure end-loaded gear pump, the flanks of the gears are sealed by two end plates 33, one for each gear, which are urged into contact with the flanks 31 of the gears by an end cover 17 secured to the pump casing 11 and sealed to the gear shafts 26 by 4 lipped packings 76. The shafts rotate bushes 27 carried by the casing. Intermediate the cover 17 and plates 33 and sandwiched between the cover and the casing are a pair of wafer members 44, 68, e.g. of phenolic resin, between which is sandwiched a gasket 56. The gasket consists of an outer web 57, two inner webs 58 and further webs 61-64 providing openings 66, 67 communicating respectively through apertures 53, 48 in the wafer member 44 with the inlet and outlet sides of the pump. A cutout 49, formed in cutting the aperture 48, is inserted in the opening 66 to support the webs. The openings 66, 67 therefore form pressure chambers with the wafer members to balance out the loads on the end plates 33.
