Abstract
Abstract A closure for the open end of a high-pressure vessel is formed of two or more plugs, in the nature of pistons that cooperate to seal the end of the vessel, each of which is supported by engagement with a portion of the wall of the vessel different from the portion or portions supporting the other plug or plugs. The plugs may be in the form of a cylindrical piston, and encircling annular pistons or a series of plugs with varying effective areas. The plugs themselves or through intermediate members are individually supported from axially spaced portions of the vessel wall.
