Abstract
A gerotor machine has a housing and a displacement unit in the housing. The displacement unit includes an inner gear wheel rotatable about an axis, and an outer gear wheel which has an axis circularly displaceable about the axis of rotation of the inner gear wheel. The gear wheels bound a plurality of displacement chambers therebetween. A plurality of recesses are formed between the teeth of one of the gear wheels, and each of the recesses has two circumferentially spaced control edges at one axial end of the one gear. The housing is provided with a plurality of control openings which are located relative to the axis of the one gear at a radial distance corresponding to that of the recesses. The control edges of the recesses of the one gear cooperate with the control openings of the housing and are operative for communicating the control openings with the chambers of the displacement unit.
