ABSTRACT:
A rotor 10 rotates inside a stator 13 eccentric with respect to the rotor. Retractable elements 11 in the form of blades are mounted pivotably on the rotor. The blades cooperate with the internal surface of the stator. The machine is useful as a pump, compressor, etc. The region where the rotor 10 and the stator 13 are in permanent fluid-tight contact is recessed in the wall of the stator, in which the rotor is partly embedded. Thus fluid-tightness between the admission and the delivery is produced not along a tangent line, but throughout a sector Z. The blades are withdrawn during passage through the zone Z.
