Abstract
The gasket makes it possible to maintain a high level of tightness, in spite of the low forces involved, through the use of a sheet of ductile material as outer envelope. Essentially, it includes a metal core (1) that is relatively elastic, enclosed by an outer envelope (2) made of ductile material, for instance a coat of aluminium. These two elements do not have any mechanical bond between them, so that possible movements and the distribution of forces are possible when the gasket is squeezed and in operation.
Claims12
An elastic metal gasket with an elastic metal core (1, 5, 11 and 12) and an outer envelope (2, 6, 13 and 14) of ductile material, into which is inserted the metal core, while the gasket, when at rest, has a circular section, characterized by the fact that the outer envelope (2, 6, 13 and 14) and the metal core (1, 5, 11 and 12) do not have any mechanical links with one another so as to be able to move and be deformed independently of each other.
