A common variable displacement pump used in vehicle technology is the axial piston pump.
This pump has several pistons in cylinders arranged parallel to each other and rotating around a central shaft.
A swashplate at one end is connected to the pistons. As the pistons rotate, the angle of the
plate causes them to move in and out of their cylinders. A rotary valve at the opposite end
from the swashplate alternately connects each cylinder to the fluid supply and delivery lines.
By changing the angle of the swashplate, the stroke of the pistons can be varied continuously.
If the swashplate is perpendicular to the axis of rotation, no fluid will flow. If it is at a sharp angle,
a large volume of fluid will be pumped.
Some pumps allow the swashplate to be moved in both directions from the zero position,
pumping fluid in either direction without reversing the rotation of the pump.
