Further Applications
- Bellows are widely used in industrial and mechanical applications such as rod boots, machinery way covers, lift covers and rail covers to protect rods, bearings and sealings from dirt.
- Bellows are widely used on articulated buses and trams, to cover the joint where the vehicle bends.
- Bellows are an essential part of anesthesia machines.
- Bellows tubing, a type of lightweight, flexible, extensible tubing may be used for delivery of gas or air at near-ambient pressure, as in early aqua-lung designs.
- Bellows PTFE with cone and socket for ground glass joints.
- Cuckoo clocks use bellows to blow air through their gedackt (pipes) and imitate the call of the Common Cuckoo bird.
- Folding and view cameras use bellows to exclude light while allowing the lens to be moved relative to the film plane for focusing and, mainly in view cameras, to allow the lens to slide and tilt to control the image (camera movements).
- Musical instruments may employ bellows as a substitute or regulator for air pressure provided by the human lungs:
- melodeon, concertina and related instruments
- Reed organ
- Pipe organ
- Musette de cour and some other varieties of bagpipes
- Harmonium and melodeon
- Portative
- Piping expansion joint: In this application, bellows are formed in series to absorb thermal movement and vibration in piping systems that transport high temperature media such as exhaust gases or steam. (8)
