Abstract
A sealing device for a high vacuum valve having a movable member which is adapted to be moved to open and close said valve, wherein a first sealing surface is formed on the movable member and a second sealing surface is formed on a housing of the valve with the first and second sealing surfaces being moved relative to each other during movement of the movable member. The first and second sealing surfaces are spaced apart when the valve is in the closed position and a solid sealing member is interposed therebetween, the sealing member being formed with an annular configuration having an inner rounded edge and an outer rounded edge adapted to be engaged between the first and second sealing surfaces. The outer edge of the annular sealing member is formed with a smaller curvature than the inner edge.
