Fluid power is a term describing hydraulics and pneumatics technologies. Both technologies use a fluid (liquid or gas) to transmit power from one location to another. With hydraulics, the fluid is a liquid (usually oil), whereas pneumatics uses a gas (usually compressed air). This introductory book, which includes over 200 color pictures, is intended to be an ideal starting point for technicians and engineers who are new to hydraulic fluid power maintenance. It is a small step towards addressing this skills shortage.Fluid power is a term describing hydraulics and pneumatics technologies.
