ABSTRACT:
A positive displacement machine with planetary motion and hypertrochoidal geometry, including an enclosure arrangement essentially constituted by a cylindrical piston (11), and a cylindrical enclosure (10) and by a third device in rotoidal connection with this piston and this enclosure, characterized in that the directrix of the piston or of the enclosure is hypertrochoidal or uniformly distant from a hypertrochoid. The machine can carry any type of fluid and can convert mechanical energy into hydraulic energy or vice versa, depending on the nature of the distribution selected for assuring the admission and escape of the fluid. This admission may furthermore be adjustable, to assure a variation in the displacement. For well-chosen geometries, the direct contact between the enclosure and the piston may be used to create the relative motion between the piston and the enclosure and to make it unnecessary to use a separate transmission.
