2. Relay valve - Wikipedia

   en.wikipedia.org/wiki/Relay_valve

   A relay valve is an air-operated valve typically used in air brake systems to remotely control the brakes at the rear of a heavy truck or semi-trailer in a tractor-trailer combination. Relay valves are necessary in heavy trucks in order to speed-up rear-brake application and release, since air takes longer to travel to the rear of the vehicle ...

3. Railway air brake - Wikipedia

   en.wikipedia.org/wiki/Railway_air_brake

   The locomotive's air compressor typically charges the main reservoir with air at 125–140 psi (8.6–9.7 bar; 860–970 kPa). The train brakes are released by admitting reduced and regulated main reservoir air pressure to the brake pipe through the engineer's automatic brake valve.

4. Air brake (road vehicle) - Wikipedia

   en.wikipedia.org/wiki/Air_brake_(road_vehicle)

   Truck air-actuated disc brake. An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle.

5. Automatic bleeding valve - Wikipedia

   en.wikipedia.org/wiki/Automatic_bleeding_valve

   Brass-bodied float valve. An automatic bleeding valve or air release valve (ARV) is a plumbing valve used to automatically release trapped air from a heating system. Air, or other gas, may collect within plumbing. For water delivery systems to taps and basins, particularly with good main supply pressure, this air is usually flushed through with ...

6. Compression release - Wikipedia

   en.wikipedia.org/wiki/Compression_release

   The most common kind of small engine compression release uses a camshaft mounted mechanical lever that pushes the exhaust valve tappet slightly, venting engine compression through the exhaust valve. Once the engine spins to starting speed, centrifugal force causes the lever to move out of the way, and the exhaust valve is allowed to seat fully.

7. Air compressor - Wikipedia

   en.wikipedia.org/wiki/Air_compressor

   Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.
