Volumetric machine with planetary movement and hypertrocoidal geometry.

摘要

Volumetric machine with planetary movement and hypertrochoidal geometry comprising an encapsulation essentially made up of a piston (11) and of a capsule (10) which are both cylindrical, as well as of a third member in rotoidal connection with this piston and this capsule, characterised in that the directrix of the piston or of the capsule is hypertrochoidal or uniformly distant from a hypertrochoid. The machine may convey any type of fluid and convert mechanical energy into fluid energy or vice versa, according to the nature of the distribution chosen to provide intake and discharge of the fluid. This intake may further be adjustable to provide a variation in the filling. For carefully chosen geometries, the direct contact between the capsule and the piston may be used to create the relative piston-capsule movement and avoid recourse to a separate transmission. <IMAGE>
