What is an axial piston pump? KNOLL Kono Pump

Axial piston pumps are positive displacement pumps that use multiple cylinders grouped around a central shaft. The group of cylinders that usually contain an odd number is called the cylinder block. The pistons in each cylinder are connected to the swash plate. The swash plate is also called a CAM or swing plate and is attached to the axis of rotation. As the shaft rotates, the Angle of the swash plate changes, which drives the pistons in and out of the respective cylinders.
Because the swash plate is at an Angle to the axis of rotation, the piston must move axially when running around the cylinder block axis. The axial motion of the piston is sinusoidal. As the piston rises, it moves towards the valve plate. At this point of rotation, fluid trapped between the embedment end of the piston and the valve plate is discharged to the discharge port of the pump through one of the semi-circular ports of the valve plate. When the piston moves back to the valve plate, the fluid is pushed through the discharge port of the valve plate.
Axial piston pumps can be designed as variable displacement piston pumps, making them useful for controlling the speed of hydraulic motors and cylinders. In this design, the swash plate is used to change the depth at which each piston extends into its cylinder as the pump rotates, thereby affecting emissions. Pressure compensator pistons are used in some designs to maintain a constant discharge pressure under varying loads. Cheaper pressure washers sometimes use a fixed rate design.
In a typical pressure compensated pump, the swash plate Angle is adjusted by the action of a valve that uses pressure feedback to ensure that the output flow of the pump is accurate enough to maintain the specified pressure. If the load flow increases, the pressure will momentarily decrease, but the pressure compensation valve will sense this decrease and then increase the swash plate Angle to increase the output flow of the pump, thereby restoring the required pressure.
The above describes what is the problem of the axial piston pump.
