Abstract
In axial plunger pump of the type wherein a swash plate is rotated while a cylinder body is kept stationary, plungers are axially slidably inserted into respective cylinder bores in the cylinder body, and the rotating swash plate cooperates with the plungers to obtain an axial stroke movement thereof for a pump operation. A stopper member is provided for cooperation with the plungers so that the stroke movement of the plunger in a direction toward the swash plate is limited. An actuator is provided for controlling an axial position of the stopper plate for obtaining desired variations of the effective stroke of the plungers.
