metal bellows are elastic vessels that can be compressed when pressure isapplied to the outside of the vessel, or extended under vacuum. When thepressure or vacuum is released, the bellows will return to its original shape(provided the material has not been stressed past its yield strength).

Bellows technology of the 20th and 21st century is centered on metalbellows. These high-technology products bear little resemblance to theoriginal leatherbellows used

traditionallyin fireplaces and forges.
