<p>The invention mainly concerns a rotor with reduced wear, and a pump comprising same. Said rotor with axis YY' comprises a blade-holder made of less hard material (37), at least one blade, an element made of a harder material for transmitting (39) a torque supplied by a driving device, for example a camshaft driven by a motor and a support component (1). The support component (1) comprises two fins radially immobile relative to the blade-holder. The support component (1) is arranged in the rotor such 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 of the element (39) to the blade-holder (37) avoiding wear of the inner surface of the blade-holder (37) caused by the transmission element (39). The invention is particularly applicable to the automotive industry. The invention is mainly applicable in the brake manufacturing industry, and more particularly for brake assist devices.</p> |
