The main body (see the structural section) drives the cylinder to rotate by the transmission shaft, so that the seven plungers evenly distributed on the cylinder rotate around the centerline of the transmission shaft, and the slide shoes in the column slide assembly are pressed against the variable head by the central spring ( Or swash plate). In this way, the plunger reciprocates with the rotation of the cylinder to complete the oil suction and oil pressure actions.

The manual variable pump changes the flow by externally adjusting the handwheel, rotating the adjusting screw, which drives the variable piston to move in the axial direction, and at the same time drives the variable head to rotate around the center, changing the tilt angle to achieve the variable purpose. The lock nut can be tightened when the required flow is reached.

When the handwheel is turned clockwise, the flow decreases. When the handwheel is turned counterclockwise, the flow increases. Its percentage value can be roughly read from the dial. Unloading is required to change the flow during work.
