Abstract

1,052,238. Rotary pump. PLESSEY-UK Ltd. Sept.25, 1963 [Oct.11, 1962], No.38468/62. Heading F1F. A gear pump or displacement motor comprises a pair of intermeshing gears having relatively prime numbers of teeth mounted on parallel axes in a cavity of a pump housing body which is secured between two end members, said housing being symmetrical both about the plane containing the gear axes and the plane perpendicular to said axes to allow the pump to be dismantled and reassembled with the housing body turned by 180 degrees about the line of intersection of said planes of symmetry. In order that the life of the housing may be lengthened after the inlet 14 Fig.2 (not shown) is worn, the housing is turned through 180 degrees so that 15 now becomes the inlet. Figs. 3 and 4 (not shown) illustrate an arrangement of grooves for sealing members in floating side plates 9a, 10a and in the side surfaces of the pump housing.
