Device and installation procedure for the connection of a tube, hose or the like to a spigot using a shape-memory alloy element.

摘要

Device for the connection of a tube (10), bellows or the like to a socket (11) with the aid of a shape-memory alloy element which contracts when it is brought to a temperature greater than its transition temperature by the Joule effect of an electric current which is applied to it. The said element (15) is associated with means (16) or is designed in such a way that its contraction is amplified by a factor such that the required clamping effect is obtained, including for shape-memory alloys having a coefficient of dimensional contraction as low as 3%. <IMAGE>
