| description | The invention relates to an internal gear pump which can also be designed as a pump with suction control. It is an object of the invention to prevent the undesirable cavitation effects in the pressure zone and to make it possible for oil to flow out from the shrinking delivery cells (17.1, 17.2) between the teeth of the gear wheels. To this end, an impedance-controlled transfer port (33) is provided whose orifices (30, 31) towards the moving delivery cells are alternately opened and closed by the teeth of at least one of the gear wheels (2, 3). |
