Inner toothed wheel machine (Pump or engine)

摘要

The inner toothed wheel machine comprises a housing (10) with an outer toothed pinion (30) which has an comb-end inner toothed hollow wheel (31). Between these, the ring gear has running fluid passages (51) on the inner-side and outer-side (32). There is a housing mount (46) on the height of the fluid passage of the hollow wheel, running in the circulation of the hollow wheel. There is an open groove (52) radial to the hollow wheel and peripheral to a low pressure pocket (43). The housing mount may be found in the circulation between two section pockets (44,45) of the low pressure pocket.
