ABSTRACT:
A positive-displacement machine comprising a piston situated in a casing. The outline of the piston is hypertrochoidal, as is the outline of the hollow inside volume of the casing. The piston has n axes of symmetry, and the casing has n+1 axes of symmetry. The piston rotates inside the casing in orbital motion about the axis .DELTA.c of the casing. To obtain the rotation in orbital motion, firstly the piston is freely rotatably mounted on a crank pin that has its axis offset relative to the axis of a supporting shaft that is coaxial with the axis .DELTA.c of the casing, the shaft being rotated, and secondly the surface of the piston and the surface of the hollow inside volume of the casing are equipped with permanent magnets creating magnetic repulsion forces.
