The controlled movement of parts or a controlled application of force is a common
Requirement in the industries. These operations are performed mainly by using the enclosed fluids (liquids and gases) to provide Controlled motion and force to the objects or substances. The specially designed enclosed fluid systems can provide both linear as well as rotary motion.
The high magnitude controlled force can also be applied by using these systems.
This kind of enclosed fluid based systems using pressurized incompressible liquids as transmission media are called as hydraulic systems.
The hydraulic system works on the principle of Pascal's law which says that the pressure in an enclosed fluid is uniform in all the directions.
