Definitions for "Bellows"
Formed metal bellows are made from tubing by the application of internal pressure. The convolutions are formed in parallel planes that are perpendicular to the longitudinal centerline of the bellows. The tubing is normally made from sheet or coil that is rolled and longitudinally welded. Seamless tubing is available for smaller diameters.
The flexible element of an expansion joint consisting of one or more convolutions.
The center section (usually in large format cameras) which connects the front (lens) to the back (camera body). The bellows is made of leather, cloth or plastic, and is accordion-pleated for flexibility and is lighttight.
An instrument, utensil, or machine, which, by alternate expansion and contraction, or by rise and fall of the top, draws in air through a valve and expels it through a tube for various purposes, as blowing fires, ventilating mines, or filling the pipes of an organ with wind.
an accessory used to blow more air into the fire, increasing combustion and producing a higher, stronger flame.
Device that produces a stream of air through a narrow tube when its sides are pressed together. It draws air through a on-way valve into a flexible chamber and then, when the sides are pressed, forces the air out.
Working a bellows, denotes a struggle, but a final triumph over poverty and fate by energy and perseverance. To dream of seeing a bellows, distant friends are longing to see you. To hear one, occult knowledge will be obtained by the help of powerful means. One fallen into disuse, portends you have wasted energies under misguiding impulses.
See aneroid capsule.
Concertina type, extendable cover for protecting linear guidance systems.
Can be manufactured from metal or non metallic materials to eliminate flexing, rolling or sliding elastomers in mechanical seal designs.
