ABSTRACT:
A displacement machine for fluids, having a displacement chamber, arranged in the manner of a groove in a fixed casing, running approximately spirally from an inlet to an outlet and spanning more than 360.degree., into which chamber a likewise essentially spiral displacement body engages, which is held eccentrically drivably in such a way so as to execute a circular movement limited by the peripheral walls of the displacement chamber, the radii of curvature of the displacement body and the said peripheral walls being dimensioned such that, during its circulating, twist-free movement, the displacement body at least virtually touches the inner and outer peripheral walls at a continuously progressing sealing line.
