Q

Define Switch

A

A device that connects and breaks an electronic circuit: turns an electric current on and off.

17
Q

Define Semi-conductor

A

A semi-conductor is a substance that can conduct electricity under some conditions, but not others. They are useful for controlling electrical current.

18
Q

Define Resistor

A

A resistor is a device that limits current in a circuit.

19
Q

Define Capacitor

A

A capacitor is a component that stores electrical charge.

20
Q

Define Motor

A

Motor converts electricity into rotary motion.

21
Q

Define Relay

A

A relay is when a small circuit is used to turn on a more powerful circuit; using an electromagnet

22
Q

Define Transformer

A

A transformer is a device that can increase, or decrease, the voltage in an alternating current circuit.

23
Q

Define LED

A

An LED allows electricity to pass through it in one direction. When it does, the diode glows.

24
Q

Define Audible Devices

A

Audible devices are components that convert noise into electricity or electricity into noise.

25
Define Single Acting Piston Cylinder
A gas or liquid forces this piston. The piston moves and applies linear motion. The piston has a spring so it moves into the position it was before the force was applied.
26
Define Double Acting Piston Cylinder
A gas or liquid forces this piston. The piston moves and applies linear motion. The fluid can go in either side, meaning the piston can move either way.
27
Define Linear Actuator
A linear actuator converts energy (from air, electricity or gas) into linear motion.
28
Define Valve
A valve is a device used for controlling the passage of fluid through a pipe or duct by opening, closing or partially blocking a pipe.
29
Define Check Valve
A one-way valve is a component designed to allow fluids to flow in one direction only. It is normally an automated system that opens/closes according to the fluid's velocity.
30
Define Pump
A pump is used to move liquids and compress gases by using suction or pressure.
31
Define One-Way Valve
A one-way valve is designed to allow fluids to flow in one direction only.
32
Define Restrictor
A restrictor limits the power of an engine. The restrictor limits the engines top speed, and increases the safety of the engine.
33
Define Quick Couplers
Quick couplers are components that allow tools to be attached onto a machine quickly.
34
Define Reservoir
In a pneumatic system there are fluid reservoirs. These store fluid to be used later in other pneumatic components. The reservoir releases the fluid when it is needed in the system.
35
Define Turbine
A turbine is a component used for producing continuous power where a wheel or rotor is made to revolve by a fast-moving flow of fluid.
36
Define Fluid Flywheel
Fluid flywheels are pneumatic components that transmit rotary power without the use of mechanical input. Instead, motion is transmitted through the fluid in the coupling.
