Orbit hydraulic motor hydraulic pump
　　Hydraulic pump oil into the hydraulic motor, hydraulic system to provide energy. Pump itself is the engine by some sort, often a gas engine-driven. The simplest hydraulic gear pump. Two meshing gears, rotating inside the case, push the front teeth, from the entrance to the export of oil. There are many other changes, including rotary vane pumps, oils, using a rotating beam is called a wind vane, and screw through the system, using a rotating screw, push the oil.
　　Hydraulic cylinder
　　In many systems, the oil hydraulic cylinder into the creation of motion. As the oil is pushed into the cylinder, it creates pressure, slide the piston. Another outlet valve can be opened to let the oil return, and send it back to the pump. This piston motors, levers, and can connect to other devices to control them. A typical example is the number of construction vehicles piston. Hydraulic cylinder controlled demolition machines such as bulldozers, shovels and weapons, for example, to improve and reduce cherry picking.

　　Hydraulic cylinder, can also be used to create rotation. This design is called axial piston motor. Piston connected to a rotary axis. Hydraulic pistons, turning the rotor. When the piston all the way out, the oil discharge, so that the motor around the rest of the way.
　　Other rotary hydraulic motor
　　Other hydraulic motor hydraulic pump work just the same way, but in reverse. For example, in hydraulic gear motor oil into the gear box. It drives the gear, put around them. Also leaves the motor, the hydraulic drive on a rotating vane, rotor spinning machine around.
　　Orbit hydraulic motor with it all
　　Hydraulic pump drive system allows a number of different devices. For example, the tank will use two hydraulic rotary motor operation track. Other rotating turret and hydraulic drive to improve and lower the barrel. Similarly, the crane can be driven, in turn, its arms, raising and lowering winch using a single hydraulic pump.
