Product Description

General Description
All control is achieved by the proper positioning of the swash plate. This is achieved by a servo piston acting on  one end of the swash plate working against the combined  effect of the off-setting forces of the pistons and centering  spring on the other end. The control spool acts as a metering valve which varies the pressure behind the servo piston. 
As shown in Figure 1, the amount of ow produced by the Parker Piston Pump is dependent upon the length of  stroke of the pumping pistons. This length of stroke, in turn, is determined by the position of the swash plate. Maximum ow is achieved at an angle of 17°. The rotating piston barrel, driven by the prime mover, moves the pistons in a circular path and the piston slippers are supported hydrostatically against the face of the swash plate. When the swash plate is in a vertical position, perpendicular to the centerline of the piston barrel, there is no piston stroke and consequently no fluid displacement, when the swash plate is positioned at an angle, the pistons are forced in and out of the barrel and uid displacement takes place. The greater the angle of the swash plate, the greater the piston stroke. The centerline of the pumping piston assembly is offset from the centerline of the swash plate. Therefore, as shown on the accompanying Figure 1A, the pistons' effective summation force tends to destroke the swash plate to a vertical (neutral) position. This destroking force is balanced as the swash plate is angled by the force of  the servo piston.
