されていることを特徴とする流体圧送装置。 A cylinder in which an inlet and an outlet are formed with different circumferential angles, a piston is driven within the cylinder, and one side has communication between the inlet and a suction/exhaust chamber side inside the cylinder, and the circumferential angle is rotated. The plunger is provided with a notch that communicates the suction and discharge chamber side with the discharge port, and a rotational drive mechanism for rotationally controlling the plunger, and the rotational drive mechanism includes a base member that reciprocates with an actuator. A fluid pumping device comprising: a drive pin erected on the base member; and a link fixed to the plunger and having a slide engagement portion with which the drive pin engages.
