Describe
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.
The swash plate angle controls the output flow of the
pump. Swash plate angle is generated by the hydraulic
force of the pumping pistons and the mechanical force
of the swash plate bias spring.
