Abstract
A hollow body, especially a pressure vessel, which includes two hollow outer parts abutting with annular end faces against each other, which define together a substantially V-shaped groove ending at its apex short of the inner surfaces of the outer parts. The outer parts are aligned with each other by an inner tubular part which extends to opposite sides of the end faces of the outer parts in close proximity with the inner surfaces of the latter. A weld seam filling the V-shaped groove connects the outer parts to each other and fusible material between the outer surface of the inner part and the inner surfaces of the outer parts join these parts to each other. The pressure vessel preferably includes also a flexible membrane having adjacent its outer edge a bead located in a groove formed in the inner part and held therein by a retaining ring.
