A sealing system for a shutoff element having two substantially ring-shaped sealing elements forming at least two substantially ring-shaped sealing lines. A given one of the sealing elements is constructed as a thin-wall body which is elastically deformable under the action of a closing force. The given sealing element, in the closed position of the shutoff element, under deformation of its wall bearing against the other sealing element at least at two ring regions with line contact. Means define free deformation spaces for the wall of the thin-wall body beneath said ring regions, and means define a respective support adjacent said deformation spaces and extending substantially parallel to the ring regions and against which bears said wall.

A sealing system for a shutoff element comprising housing and blocking members of the shutoff element, an annular metallic sealing element extending between said housing and blocking members [and sealingly connected to one of said members]and having a contact portion defined as all the area clamped between said members by a closing movement of said blocking member with at least one of the inner and outer peripheries of said sealing element not connected to said housing member or said blocking member, said [annular sealing element]contact portion having a thin walled [portion which is]construction of substantially the same thickness throughout, and being elastically deformable under a closing force between said housing and blocking members and [extends]extending through an annular width of said sealing element with a wall thickness of said entire contact portion to allow deformation of said contact portion, at least two annular supporting areas on each of said housing and blocking members which under the closing force make sealing linear contact with and deform said thin walled contact portion of said sealing element, and free spaces for deformation of said thin walled contact portion therein, under the maximal closing force, on opposite sides of said thin walled contact portion from each of said annular supporting areas and enclosed by said thin walled contact portion and said other member than said member making the linear contact at the annular supporting area[,]. [said annular supporting areas adjacent each of said free spaces for deformation, and said spaces on a member extending substantially parallel to said supporting areas on said same member.]
