Abstract

1395817 Rotary positive-displacement machines DANFOSS AS 10 May 1972 [14 May 1971] 21878/72 Heading F1F In a gerotor-type pump, or motor, to compensate for back-lash in a coupling (not shown) between a planetary toothed-wheel 3 and a rotary member 13 of a working-fluid distributing- valve, grooves 18, 19 are formed in an end-wall 21 attached to a fixed toothed-ring 1 so as to interconnect working-chambers 5, 6, 7 and 8, 9, 10 on the high and low pressure sides. The groove 18 associated with an intermediate working- chamber 11 prevents excessive pressure devloping in the latter. The wheel 3 prohibits communication between the grooves 18 related to the chambers 7, 8. The circumferential lengths of openings 14, 15, 16 may be reduced, as indicated by broken and full lines, Fig. 1. Instead of the grooves 18, 19, grooves 22 may be formed in each end of the wheel 3, Figs. 5 and 7.
