POE Fluid Power Key Terms

3. A device used to create flow in a hydraulic system.
4. Any device that controls, either automatically or manually, the flow of a fluid.
5. The use of gas flowing under pressure to transmit power from one location to another.
6. Law The volume of a gas at constant temperature varies inversely with the pressure exerted on it.
8. Cylinder A cylinder that can act under pressure in both directions (extend and retract) to move a load.
9. Law States that the volume of a confined gas is proportional to its temperature, provided its pressure remains constant.
11. The tank that holds the fluid in a hydraulic system.
13. Pressure The pressure exerted by the weight of the atmosphere above the point of measurement.
16. An air pump that compresses air into a receiver tank.
18. Valve Used to start and stop flow in a circuit.
20. Law The absolute pressure of a confined gas is proportional to its temperature, provided its volume stays constant.
22. A part of an axle or shaft bent out at right angles, for converting reciprocal to circular motion and vice versa.
23. The force per unit area exerted by a fluid against a surface.
24. Lines Used to transport fluid in a circuit.
26. Power The use of a fluid (liquid or gas) to transmit power from one location to another.
27. Cylinder A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.

1. The amount or quantity of something.
2. A device used to spray an oil mist into the stream of a pneumatic system.
4. A measure of a fluid’s thickness or resistance to flow.
7. Velocity The distance the fluid travels through a system in a given period of time.
8. Valve Used to control which path fluid takes in a circuit.
10. A switching device that uses the magnetic field generated by an electrical current for actuation.
12. Tank A device that holds the compressed air in a pneumatic system.
14. A device used to convert fluid power into mechanical power in the form of linear motion.
15. A sliding piece moved by or moving against fluid pressure which usually consists of a short cylindrical body fitting within a cylindrical chamber or vessel along which it moves back and forth.
17. Law Pressure exerted by a confined fluid acts undiminished equally in all directions.
19. The use of a liquid flowing under pressure to transmit power from one location to another.
21. Pressure The total pressure exerted on a system, including atmospheric pressure.
25. A device used to remove contamination from a fluid.
28. Valve A valve that allows flow in one direction but prevents flow in the opposite direction.
