容量形液体ポンプ。 A main body having a liquid suction passage and a discharge passage is provided with at least two overlapping valve plates each having a semicircular-arc suction port and a discharge port that communicate with the liquid suction passage and discharge passage. , has a pump chamber that alternately communicates with the suction port and discharge port of the valve plate by rotational drive, and the liquid sucked into the pump chamber from the suction passage through the suction port is discharged from the discharge passage through the discharge port. A rotating body is rotatably supported in the main body and slidably contacts the valve plate, and a discharge amount changing member is provided in the valve body so as to freely change the amount of liquid discharged from the discharge flow path. A variable displacement liquid pump consisting of two valve plates that are relatively rotatable to change the timing of communication between the pump chamber and the port in the rotating body in accordance with the change in the amount of discharged liquid, and the port length can be changed. .
