Abstract (en)
A rotor for pneumatic motor comprising a stator cavity (2) wherein the rotor (5) is rotatably housed, comprises a substantially cylindrical body (7) wherein a circumferential series of radial notches (8) is formed, said notches extending along the whole length of the cylindrical body (7) itself and forming the same number of seats for respective radial blades (9) slidingly inserted in said notches (8); each of said notches (8) is related to at least one respective conduit (11) formed in said cylindrical body (7) separately and further forward in relation to said notch (8) in the direction of rotation of the rotor (5) and leading into the stator cavity (2) and into the base of the respective notch (8), to allow a pressurised fluid to penetrate the base of said notches (8) to force said blades (9) into a condition of forced engagement with an internal surface of said stator cavity (2). <MATH>
