Hydraulic Pump Motor
A hydraulic pump motor is a device that is composed of three main parts: a reservoir, a pump, and a hydraulic cylinder. These components work together to convert hydraulic energy into mechanical energy. This energy is then used to power various automobile parts and construction machinery.

How Hydraulic Cylinders Work
Hydraulic cylinders, which are one aspect of the three part hydraulic pump motors, have two chambers and a piston rod. The basic concept behind hydraulic systems is fairly simple: the force applied to incompressible liquid triggers linear motion (a process called actuation) in a piston. When the hydraulic fluid is pumped into the bottom chamber of a hydraulic cylinder, the piston rod is pushed up, pushing the fluid in the other chamber back into the reservoir. This process pressurizes the chamber and extends the piston to its full length, giving the hydraulic cylinder its ability to push. Hydraulic pump motors and hydraulic motors are often used in construction vehicles, automobiles, and aircraft. Many industrial types of machinery employ hydraulic motors for a specific action that requires heavy lifting or will experience strong pressure.
