Abstract
1501343 Rotary positive-displacement pumps IMO-INDUSTRI AB 15 April 1976 [2 May 1975] 15647/76 Heading F1F In a meshing-screw pump the or each idler screw 9b has a bearing pin 21 at its high-pressure end mounted in a sleeve 22 forming a chamber 27, connected via passages 28, 29, 30, 32, 31 in the housing and drive screw 9a, with the low-pressure end of the pump, a disc-shaped gasket 35 being mounted between an end-face of the sleeve and an end cover 2, the sleeve having, on a surface remote from the gasket and co-operating with a fixed surface 24a of the housing a deformable portion, (as shown, an annular lip 39). Thus the idler screws 9b are exposed to low-pressure at each end, and the lips 39 improve the sealing of the gasket to prevent high-pressure liquid leaking into chamber 27.
