Abstract
The metal elastic gasket can tolerate considerable clamping forces without causing any degradation to sealing by possible deformation. It consists of a metal core (12) enclosed in an outer envelope (13) that is more ductile. On the side, the latter has clearance surface areas (16) to be placed opposite the surface areas (1) enclosing the gasket (10), with a projecting part (14) placed so as to be offset with respect to centre axis (M) of the gasket. This avoids any decrease in the contact pressure of the gasket on the surface areas (1) during crushing, when the projecting part is centred.
Claims12
A elastic metal closed gasket (10, 20) having an elastic metal core and an outer envelope (13, 23) of ductile material, into which is inserted the metal core (12, 22), while the gasket (10), when idle, has a closed circular section defining a middle axis (M), i.e., a straight line passing through the geometrical centre of the idle gasket section which has 2 clearance surfaces (16, 26) placed opposite each other and each of which has at least one projecting part (14, 24) and whose apex is designed to come into tight contact with an object (1) under the effect of a determined tightening force, characterized by the fact that, when idle, the projecting parts (14, 24) are offset slightly with respect to middle axis (M) of the gasket (10, 20).
