Example:

The piston pump (work tool) (1) is a variable displacement axial piston pump. The piston pump is
controlled by a load sensing line. The pump is used to supply pressure oil to the work tool control
valve. The movement of pistons (8) in the pump pulls oil from the hydraulic tank. The pressure oil
from the hydraulic pump supplies the work tool control valve.
When the engine is in operation and drive shaft (11) is rotating, the components that rotate are
cylinder barrel (14), pistons (8), slipper pads (9), and the slipper retainer (13). There are nine
piston assemblies in the barrel assembly. The components of the pump that remain are fastened to
pump housing (10) .
Oil from the hydraulic tank flows into pump head (5) at inlet passage (4). The oil then flows from
inlet passage (4) through inlet passages in valve plate (16). When drive shaft (11) turns, the
openings of cylinder barrel (14) move toward the inlet passages of valve plate (16) .
Each piston (8) inside cylinder barrel (14) is held against swashplate (12) by the slipper retainer
(10). Swashplate (12) can be at any angle between the maximum angle and the minimum angle.
As pistons (8) follow the angle of swashplate (12), the pistons move in and out of cylinder barrel
(14). When pistons (8) move out of cylinder barrel (14), oil is pulled into cylinder barrel (14) .
The angle of swashplate (12) determines the amount of oil that is drawn into cylinder barrel (14).
As cylinder barrel (14) rotates, the swashplate angle pushes pistons (8) back into cylinder barrel
(14). Pistons (8) will then push oil out of cylinder barrel (14). The oil then flows through the outlet
passages of valve plate (16) .
The angle of swashplate (12) determines the amount of oil that is pushed out of cylinder barrel
(14) .
There are infinite swashplate angle positions. Swashplate (12) can be at any angle between the
minimum angle and the maximum angle. The minimum angle is perpendicular with drive shaft
(11). The discharge of oil is greater when the angle of swashplate (12) is greater. Oil is discharged
through valve plate (16) to outlet passage (3) .
When swashplate (12) is at a minimum angle, pistons (8) do not move in and out of rotating
cylinder barrel (14). Therefore, no oil is drawn into the pump. No oil is pumped out of the pump.
The pump has zero displacement and zero flow.
If swashplate (12) is at the maximum angle, then the pump is at the maximum displacement or at
full flow of the pump.
