Hydro-pneumatic pressure vessel

摘要

A pressure vessel having a housing subdivided by a flexible partition into an upper gas portion and a lower liquid portion. The gas portion of the housing forms a gas chamber surrounding by an upper wall formed of curved lines of various radius. An inlet to receive a pressure gas is formed in the upper wall so that the inlet is positioned in the area of the upper wall outlined with a curve of a minimal radius. After loading of the pressure vessel with a gas under relatively high pressure the inlet is sealed by a locking element. In the area where the inlet with the locking element is positioned, the deformations exerted on the wall under gas pressure are minimal.
