Abstract

1535874 Rotary positive-displacement fluidmachines ROBERT BOSCH GmbH 3 Aug 1976 [16 Aug 1975] 32347/76 Heading F1F In a liquid pump of the sliding-vane type a pressure-equalizing bore 38 extends through the rotor 16 and a shaft 17 thereof, the latter being connected to a driving spindle 23 by a coupling 21 rotatively mounted in the housing 10. The resultant axial thrust is transmitted by way of the coupling to a ball bearing 30. Another embodiment, Fig. 3 (not shown), differs mainly in that the rotor also has a stub shaft on its side farthest from the coupling, a bearing bush for the stub shaft being furnished with a sealing ring in its inner surface.
