ROTOR FOR VANE PUMP

摘要

The invention concerns a rotor with axis (YY') comprising a blade-holder made of less hard material (37), at least one blade, an element made of harder material for transmission (39) of a torque supplied by a drive device, for example a camshaft driven by a motor, and a support part (1). The support part (1) comprises two fins radially fixed relative to the blade-holder. The support part (1) is arranged inside the rotor so that the fins (3, 5) extend between the blade-holder (37) and the transmission element (38) at the support surfaces subjected to wear so as to transmit the support element (39) to the blade holder (37) thereby preventing the wear of the inner surface of the blade-holder (27) caused by the transmission element (39).
