Types, Principles, and Applications. Introduction. An actuator can work as a mechanical or electro-mechanical tool transforming energy, usually in the form of electricity, hydraulics, or pneumatics, into regulated motion or force. Many different systems use these devices, enabling them to precisely control and move things.
Fluid power actuators receive fluid from a pump (typically driven by an electric motor). After the fluid has been pressure, flow, and directionally controlled, the actuator converts its energy into rotary or linear motion to do useful work. Cylinders account for more than 90% of the actuators used in fluid power systems for work output.

Hydraulic Cylinders and Motors. Hydraulic actuators are moved by forcing a liquid, usually a heavy oil or specialized hydraulic fluid, into the system. Unlike pneumatic and steam actuators, the hydraulic fluid is virtually incompressible. Very little energy is lost compressing the fluid, but instead, is used for motion of the actuating component.
Hydraulic actuators are the ones that utilize the energy contained by fluids in the form of pressure to generate motion or mechanical energy. They contain piston and cylindrical tube assemblies to generate motion, either linear, oscillatory, or rotary. These devices are very robust and capable of withstanding harsh weather conditions.
