Terms | Definitions |
|---|---|
 Absolute Pressure | The total pressure exerted on a system, including atmospheric pressure. |
| Atmospheric Pressure | The pressure exerted by the weight of the atmosphere above the point of measurement. |
| Boyle's Law | The volume of a gas at constant temperature varies inversely with the pressure exerted on it. |
| Charles' Law | States that the volume of a confined gas is proportional to its temperature, provided its pressure remains constant |
| Check Valve | A valve that allows flow in one direction but prevents flow in the opposite direction. |
| Compressor | An air pump that compresses air into a receiver tank. |
| Crank | A part of an axle or shaft bent out at right angles, for converting reciprocal to circular motion and vice versa. |
| Cylinder | A device used to convert fluid power into mechanical power in the form of linear motion. |
| Directional-Control Valve | Used to control which path fluid takes in a circuit. |
| Double-Acting Cylinder | A cylinder that can act under pressure in both directions (extend and retract) to move a load. |
| Filter | A device used to remove contamination from a fluid |
| Flow Meter | A device used to measure flow rate. |
| Flow Rate | The volume of fluid that moves through a system in a given period of time. |
| Flow Velocity | The distance the fluid travels through a system in a given period of time. |
| Flow-Control Valve | Used to start and stop flow in a circuit |
| Fluid Power | The use of a fluid (liquid or gas) to transmit power from one location to another. |
| Gay-Lussac's Law | The absolute pressure of a confined gas is proportional to its temperature, provided its volume stays constant |
| Hydraulics | The use of a liquid flowing under pressure to transmit power from one location to another |
| Lubricator | A device used to spray an oil mist into the stream of a pneumatic system. |
| Pascal's Law | Pressure exerted by a confined fluid acts undiminished equally in all directions |
| Piston | 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. |
| Pneumatics | The use of gas flowing under pressure to transmit power from one location to another. |
| Pressure | The force per unit area exerted by a fluid against a surface |
| Pressure Regulator | A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit. |
| Pressure Relief Valve | A type of pressure control valve that limits the maximum pressure in a hydraulic or pneumatic circuit. |
| Pump | A device used to create flow in a hydraulic system. |
| Receiver Tank | A device that holds the compressed air in a pneumatic system. |
| Reservoir | The tank that holds the fluid in a hydraulic system. |
| Single-Acting Cylinder | A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released. |
| Solenoid | A switching device that uses the magnetic field generated by an electrical current for actuation. |
| Transmission Lines | Used to transport fluid in a circuit |
| Valve | Any device that controls, either automatically or manually, the flow of a fluid. |
| Viscosity | A measure of a fluid's thickness or resistance to flow. |
| Volume | The amount or quantity of something. |
