Abstract

1501990 Rotary positive-displacement fluidmachines ROBERT BOSCH GmbH 25 April 1975 [3 Aug 1974] 17165/75 Heading FIF In a compressor having an eccentric piston 10 co-operating with a radially-sliding vane 3 in the housing 1 the angle # between lines perpendicular to the longitudinal axes M1, M2, M3, of a driveshaft 6, the piston, and an eccentric 7 fixed to the shaft, respectively, is between 20 degrees and 40 degrees. This arrangement is said to eliminate lifting of the piston from the wall of a bore 2 therefor or at least to prevent such lifting other than when the piston is in its upper dead-centre position. The piston is journalled by e.g. needle rollers 9, on an intermediate eccentric 8. Inlet and outlet ports 4, 5 may be disposed as shown.
