Title: ROTATING VOLUMETRIC MACHINE WITH RADIAL PISTONS
Abstract:
Rotating volumetric machine (1) with radial pistons wherein one between the inner ring (16) and the joint (25), that connects in rotation the inner ring (16) and the relative rotor element (7), comprises at least a first seat (26) and the other supports in rotation at least a first revolving element (27) around a relative axis (27a), the first revolving element (27) being fitted in said first seat (26) and cooperating with it to transmit a torque to the joint (25); wherein at least one between the rotor element (7) and the joint (25) comprises at least a second seat (28) and the other supports in rotation at least a second revolving element (29) around a relative axis (29a), the second revolving element (29) being fitted in the second seat (28) and cooperating with it to transmit a torque to the rotor element (7); the first and the second revolving element (27, 29) rolling around the respective axes (27a, 29a) along at least a containment wall (26a, 28a) delimiting the respective seats (26, 28) during the rotation of the inner ring (16) and of the rotor element (7).
