The high-pressure aqueous acts aloft the rod and agent aural a hydraulic cylinder. Anniversary achievement of the butt converts the aqueous ability (pressure) into plan (mechanical force). The backlog oil akin avalanche while the rod and agent are extending.

When the rod and agent retract, the aqueous allotment to the reservoir. The metal walls of the backlog air-conditioned the aqueous by acceptance calefaction to escape. The bargain burden in the backlog aswell allows trapped or attenuated air to escape from the fluid. If cylinders have to abbreviate air bubbles, the ability of the arrangement is reduced.

There are two types of valves, directional ascendancy valves and burden abatement valves. Directional ascendancy valves administer the breeze aisle of the aqueous in the system. Burden abatement valves assure the arrangement accouterments and apparatus adjoin burden overloads. They aswell absolute the achievement force exerted by rotary motors and cylinders. These valves accessible whenever the burden goes above the set value, acceptance oil to breeze aback into the reservoir.

The aqueous campaign from one basic to the next aural a hydraulic arrangement through a hydraulic hose.
