Abstract (en)
[origin: CA2501103A1] The invention relates to a displacement pump with variable volume flow. T he pump comprises a casing with a chamber formed therein which includes an inle t opening on a low pressure side and an outlet opening on a high pressure side for a fluid. The pump further comprises an internal rotor which is accommodated in the chamber and has a central ring axis which surrounds the internal rotor. In t he case of rotary driving, at least one of the internal rotor and the ring forms, together with the internal rotor, at least one delivery cell in which the fluid is delivered from the low pressure side to the high pressure side. An adjusting device is arranged suc h that during an adjusting movement, it rolls off on the casing without slipping. I n accordance with the invention, the internal rotor is fixed to the adjusting device such that it can be rotated about the rotational axis. As well, the position of t he rotational axis relative to the ring axis of the ring is adjusted by the adjusting movement of the adjusting device.
