Abstract

839,648. Rotary vacuum pumps. SHORROCK SUPERCHARGERS Ltd. Feb. 10, 1958 [Feb. 18, 1957], No. 5366/57. Class 110 (2). In a rotary vacuum pump of the outwardly sliding radial vane type the vanes 9 are loaded by means of a metal ring 29 which has a covering 30 of synthetic rubber and is fixed to or rotatably mounted on the flange 27 of a thrust plate 24. The thrust plates are formed with labyrinth grooves 28 and bear against a compressible disc 25. The composite ring 29, 30 may be provided with an outer metallic covering.
