徴とするアキシヤルプランジヤーポンプ。 The cylinder block is rotatably driven by a power source, a plunger is slidably incorporated into the cylinder block, and a swash plate is swingably supported in contact with the plunger. In an axial plunger pump in which the stroke of the plunger is variable depending on changes in the stroke of the plunger, there is provided a control piston that presses the swash plate in a direction that increases the inclination angle in accordance with an increase in discharge hydraulic pressure of the pump, and a control piston that presses the swash plate in a direction that increases the inclination angle. An axial plunger pump characterized by comprising: a spring means for pressing in a direction in which the axial plunger pump becomes smaller.
