Abstract

Device to create a seal around a rotary shaft, which includes a seal maintaining contact sealed with shaft, or bonded part to it, through a system which exerts a spring force on board and it comprises at least one spring element, of which at least some of its parts are made of a memory metal, that is, a metal that remembers its shape to a certain temperature and recover this form when it reaches that temperature, characterized that at least part of the spring (4, 10) is connected to an electrical source (7) so you can send an electric current through this part.
