Abstract
The machine includes a piston which is cylindrical in the mathematical sense, which has an axis .DELTA..sub.p, which is rotary, and which is situated in a cylindrical casing that has an axis .DELTA..sub.c, the piston having an outline that has .DELTA..sub.p axes of symmetry, the casing delimiting a hollow volume whose cross-section in a plane perpendicular to its axis .DELTA..sub.c has S.sub.c axes of symmetry, S.sub.p and S.sub.c differing from each other by unity. The axes .DELTA..sub.p and .DELTA..sub.c are parallel and are separated by a distance E, the piston and the casing delimiting at least three chambers between them, and the casing including at least one suction inlet and one delivery outlet. The positive-displacement machine further includes a ferromagnetic sprocket which has an axis .DELTA..sub.p, which is secured to the piston, which has N.sub.p teeth, and which is disposed inside a ferromagnetic toothed ring which has an axis .DELTA..sub.c and which is secured to the casing, the toothed ring being provided with N.sub.B electrical windings disposed radially, wherein the ratio N.sub.p /N.sub.B is equal to the ratio S.sub.p /S.sub.c, and wherein the N.sub.B electrical wi…
