ABSTRACT:
A sealing arrangement specifically for shut off devices is disclosed. A shut off device has two annular metallic sealing members of which one is a rigid body and the other is a thin-walled elastically deformable body. One of the sealing members features a considerable large hardness. The other sealing member comprises a coating of a soft metal, filling all irregularities of the surface thereof. Upon closing of the shut off device the surfaces of the two sealing members rub against each other, whereby the coating of soft metal is rubbed off until portions thereof remain in the recesses of the metal forming the substrate of this sealing member. This assures an excellent sealing of the shut off device.
