Abstract: A pressure vessel includes a body 10 and a cover 12. An O-ring 20 surroung the upper opening 11 of the vessel body 10 cooperates with a diaphragm 21 sealingly inserted in the cover 12. The diaphragm 21 extends beyond the O-ring 20 in the radial direction inside the cover 12. When the vessel is pressurized, a pressure difference acts on the diaphragm 21 to press an annular plate 23 driven by the diaphragm 21 against the O-ring 20, while the cover 12 is secured by a bayonet locking 24, 25 against being lifted off the vessel body. The pressure inside the vessel is thus used to produce the sealing force. In the unpressurized condition, the cover 12 may be easily placed on the vessel body 10 without effort, and rotation about a small angle is sufficient for securing the cover. In case the bayonet locking has not been completely closed, pressure applied to the vessel will lift the cover 12 by a certain amount, thereby automatically releasing the seal.
