The Hydraulic Pump

 · A variable-displacement pump is more sophisticated. It has a series of piston cylinders fixed in a ring inside a barrel. The engine spins the barrel around so that the cylinders revolve. The cylinder pistons extend out the back of the barrel, where they are attached to an angled swash plate.As the barrel spins around, the angle of the swash plate pushes the pistons in and then pulls them out.
