Parker plunger pump PAVC10038R4222 is a Parker PAVC variable piston pump that works by a servo piston acting on one end of the swash plate to overcome the bias of the plungers and the combined force of the centering springs at the other end. The control spool acts as a throttle valve, changing the pressure behind the servo piston. The rotating cylinder driven by the prime mover moves the plungers along a circular path and the plunger shoes are supported on the end surface of the swash plate by static pressure. When the swash plate is in the vertical position where the center line of the cylinder is vertical, there is no plunger stroke and thus no oil displacement. When the swash plate is positioned at an angle, the plungers are forced into and out of the cylinder and oil displacement occurs. The larger the swash plate angle, the greater the plunger stroke. The center line of the pump plunger assembly is offset from the center line of the swash plate, and the resultant force of the plungers tends to return the swash plate to a vertical (neutral) position. This return force is balanced when the swash plate is tilted by the force of the servo piston.
