HPV95+95 VARIABLE DISPLACEMENT PISTON PUMP
112 CC PER PUMP MAX DISPLACEMENT
Controlled by 2 LS valves and 2 PC valves
With an LS EPC and PC EPC
mounted on the side of the pump body
The two pumps can work independently or together as one.
Control of Discharge Amount.
Servo piston moves in a reciprocal movement, according to the signal pressure from the LS or PC valves. This movement is transmitted through the rod to the rocker cam to increase or decrease swash plate angle.
Operation of Pump.
Cylinder block is splined onto input shaft and all rotate together.
When the rocker cam is in the minimum swash plate angle. The volume in the inlet and outlet chamber are the same, discharging a small flow of oil.
The rocker cam is moved into the maximum position, volume in the inlet chamber become larger than the out-let. Causing a greater flow of oil.
The swash plate angle on this pump never becomes 0
LS Valve: Detects the load and controls the pump discharge amount.
The pump discharge or flow is proportional to differential pressure.
