ABSTRACT:
A rotary volumetric machine includes a stator in which a cylindrical chamber is provided, a rotor disposed therein and secured to a shaft, blades formed on the rotor, and abutments movable by actuating elements between an extended position into the volume of the cylindrical chamber during the working phase so as to generate variations of volume between the blades and the abutments, and a position retracted into the stator to permit the passage of the blades from one side to the other of the abutments. The rotor includes a disc, two concentric shoulders disposed on opposite sides of the disc and two fixed blades disposed diametrically opposite on opposite sides of the disc each against one surface thereof and secured to the periphery of a shoulder so as to obtain an assembly balanced in rotation.
