Abstract

PURPOSE: To prevent a leakage of liquid at time of high pressure by providing a rotary body which presses each sliding member against the wall of a cylindrical cavity in a freely moving fashion in a rotary and radius direction at a center where plural sliding grooves provided radially extending from the center of a rotor.
CONSTITUTION: If a rotor 10 is rotated in an arrow direction, a sliding member 13 pushes its way out in the direction of a discharge port 4, compressing a fluid inside a pump chamber 9 and a fluid is sucked into a suction port 3 because of a one-sided expansion of the volume of the pump chamber 9. In this case, the sliding member 13 inserted in a freely sliding manner inside sliding grooves 12 provided radially extending from the center of a rotor 10 presses the sliding member 13 against the wall of the cylindrical cavity 2 at the center of the rotor 10 where the sliding grooves 12 converge. The sliding member 13 is always pressed against the cylindrical cavity 2 wall by means of a rotary body 15 provided in a freely moving way in a rotary and radius direction and won't leave the wall, even if a pressure inside the pump chamber 9 were high, thus preventing a leakage.
