2. Pneumatic motor - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_motor

   A pneumatic motor (air motor), or compressed-air engine, is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed-air energy to mechanical work through either linear or rotary motion.

3. Pneumatic actuator - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_actuator

   It keeps the air in the upper portion of the cylinder, allowing air pressure to force the diaphragm or piston to move the valve stem or rotate the valve control element. Valves require little pressure to operate and usually double or triple the input force. The larger the size of the piston, the larger the output pressure can be.

4. Pneumatics - Wikipedia

   en.wikipedia.org/wiki/Pneumatics

   Pneumatics (from Greek πνεῦμα pneuma 'wind, breath') is the use of gas or pressurized air in mechanical systems. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other ...

5. Air-operated valve - Wikipedia

   en.wikipedia.org/wiki/Air-operated_valve

   An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate. Whether the valve opens or closes depends on ...

6. Airlift pump - Wikipedia

   en.wikipedia.org/wiki/Airlift_pump

   Airlift pumps are often used in deep dirty wells where sand would quickly abrade mechanical parts. (The compressor is on the surface and no mechanical parts are needed in the well). However airlift wells must be much deeper than the water table to allow for submergence. Air is generally pumped at least as deep under the water as the water is to ...

7. Radial engine - Wikipedia

   en.wikipedia.org/wiki/Radial_engine

   Kurt Tank designed a new cooling system for this engine that used a high-speed fan to blow compressed air into channels that carry air to the middle of the banks, where a series of baffles directed the air over all of the cylinders. This allowed the cowling to be tightly fitted around the engine, reducing drag, while still providing (after a ...
