The basic form of axial piston pumps are flange-mounted, if the motor is used to drive, it is necessary to manufacture a "mounting body", using this connection method can eliminate the coaxiality error of the two axes of the drive machine shaft and the piston pump shaft, the small end of the flange and the piston pump flange connection.

In the direction of rotation, when the cylinder rotating angle is within the range of π to 2π, the plunger extends outward, the sealing working volume of the cylinder hole at the bottom of the plunger increases, and the oil is sucked through the oil suction window of the oil distribution plate; in the range of 0 to π, the plunger is pushed into the cylinder by the inclined plate, so that the cylinder hole volume decreases, and the oil is pressed through the pressure window of the oil distribution plate. Cylinder every turn a week, each plunger to complete the suction, pressure oil once, such as changing the inclination of the swash plate, you can change the length of the plunger stroke, that is, to change the displacement of the hydraulic pump, change the direction of the inclination of the swash plate, you can change the direction of the suction and pressure, that is, it has become a bi-directional variable pump.
