Abstract
The rotor (3) provides recesses which house the vanes and is arranged for rotation in the cylindrical seat (4). A quantity of oil, contained in the pump, is expelled from the pump when it rotates and is collected in the space (15) between a ring (4) and a supporting container (8) for the ring. The oil is returned from this space to the pump when it stops. The outlet opening (10) of the cylindrical seat is arranged to force the air, which leaves it, to flow circumferentially through the toroidal space (15) about the cylindrical seat (5). This provides a centrifugal force which separates tha oil to flow over and cool the outer surface of the cylindrical seat of the pump.
