Abstract
PURPOSE: To lighten driving torque and variation of torque by securing a sufficient dimension of the area of flow passage to discharge port and preventing the formation of shutting-in chamber and preventing both the generation of high pressure in compression stroke and the generation of shutting-in pressure.
CONSTITUTION: In the outer peripheral surface of a rotor 5, cut parts 9 which extend to the leading edges of their respective slits 6 are formed. The length of each cut part 9 in the direction of revolution callows the area of flow passage in which a vane 7 opposite to a discharge port 2 goes to the discharge port 2 to increase and allows the shutting-in chamber which tends to be formed immediately after the vane 7 passes through the discharge port 2 to communicate to the subsequent intake chamber. The fluid pressure has the highest value when the vane 7 reaches immediately before the discharge port 2, but at this time, the area of the flow passage which leads to the discharge port 2 is increased by the cut part 9 formed on the peripheral surface of the rotor, so the flow passage resistance can be reduced.
