Abstract

PURPOSE: To enabling pumping action, by providing a vane between a suction and a discharge ports.
CONSTITUTION: A vane 2 is provided between a suction port 1 and a discharge port 8. When a rotor 3 is rotated, a substance introduced through the suction port 1 is sucked with the expansion of volume by the rotation of the rotor 3. The suction is continued at the left of the vane 2 until the flat part 6' of a rotor 3 at its top is revolved by 360° to the original position, so that the sucked substance is continuously discharged out of the volume defined by the right of the vane 2 and the flat surface 6' of a protruded part. Pumping action is thus enabled.
