Hydraulic Radial Piston Pump

The principle of operation of the radial piston pump is shown in Fig. 4.16. In this case, the cylinders are positioned radially around the axis of rotation. As the shaft rotates, the connecting rods push the pistons back and forth in the cylinders to develop the pumping action. The design is used to pump both liquids and gases but, in the fluid power industry, it is more commonly used for pneumatic systems.
