Abstract

It consists in giving the top 6 of the wheel 1 of the pump a damper 7 made from an elastomeric material of suitable hardness, which is encased between said stop 6 and the lateral wall of the wheel 1, the ends 9 of which damper project substantially from the actual top 6, constituting the zones of impact for the entrainment cam 5 associated with the rotor of the motor. In this way, the operation for starting up the movement of the entrainment cam 5 impacts on a soft, elastic element which absorbs a large part of the energy and minimizes noise. <IMAGE>
