Abstract
1492327 Externally meshing gear pumps and motors ROBERT BOSCH GmbH 10 Sept 1975 [12 Sept 1974] 37247/75 Heading F1F Excessive high pressures on the peripheral surfaces of the bearing bushes of an externally meshing gear pump or motor are prevented by creating a low pressure zone 51 between the peripheral surface of the bush and the associated housing bore. The peripheral surface of each bush, e.g. 16, is given a rectangular groove 47, 48, 49, 50 in which is located a seal 52 which encloses zone 51. This zone extends from adjacent the high pressure side of the machine for about 120 degrees and is connected to an annular low pressure space 21 adjacent the outer end of the bearing bush 16 by a groove 55 in the bush 16. Space 21 is connected by recesses 64 to the low pressure side of the pump.
