operation of machinery and equipment by a fluid that is under pressure, two examples being masts that raise elevator platforms or forks on a lift truck
Regulates hydraulic pressure at a predetermined pressure setting so not to cause damage to hydraulic system.
Pressure by the hydraulic pump is made​​.
The pump in a hydraulic system forces fluid out and that creates pressure
Torque hydraulic motors is done by oil pressure and oil pressure is caused by the hydraulic pump. The hydraulic pumps produce higher pressure gets too much torque.

Hydraulic pump that produces pressure in a hydraulic system. It takes energy to pump the electric motor or engine mechanical.
The formula for converting flow to pressure in a hydraulic system is: Pressure Flow x Resistance.
Because they are actuated by fluid pressure, rather than pneumatic (air) pressure.
At the pressure regulator.
A power source - such as a combustion engine or electric motor - mechanically actuates a pump which pushes hydraulic fluid through it. This maintains pressure in the hydraulic system.
For measuring the flow of hydraulic fluid.
Hydraulic , the jack uses fluid under pressure to raise the cylinder , releasing the pressure allows the cylinder to retract. Pneumatics is a similar concept using air pressure.
