Fluid power is energy transmitted and controlled by means of a
pressurized fluid, either liquid or gas. The term fluid power
applies to both hydraulics and pneumatics. Hydraulics uses
pressurized liquid, for example, oil or water; pneumatics uses
compressed air or other neutral gases. Fluid power can be
effectively combined with other technologies through the use
of sensors, transducers and microprocessors.
fluid power works
Law expresses the central concept of fluid power:
"Pressure exerted by a confined fluid acts undiminished
equally in all directions."
force of 10 pounds (44.8 N) on a 1-square-inch (6.45 cm2)
piston develops a pressure of 10 pounds per square inch (psi)
(68.95 kN/m2 or 68.95 KPa) throughout the
container. This pressure will allow a 10-square-inch piston to
support a 100-pound (444.8 N) weight. The forces are
proportional to the piston areas.

power products are sold as individual components or as
systems for the original equipment manufacturing, maintenance,
repair and replacement markets.
A typical fluid power system includes the following components:
