HIGH-PRESSURE CYLINDER Russian patent published in 2008 - IPC F17C1/00 

FIELD: mechanics, pneumatics.

SUBSTANCE: invention relates to the designs of vessels operated under pressure and may be used in gas cylinders to store and carry liquefied natural gas used in automobiles and fire-fighting systems. The high-pressure cylinder contains a sealing vessel, i.e. a lining tube with, at least, one neck with a locking device, the cylinder outer surface is made in the form of a strengthening composite shell covering the lining tube. The other neck accommodates a plug incorporating a safety device with a trap for fragments of destructed membrane, the said device being made from a material withstanding the pressures, without destruction, over (2.6+Δ%)P where Δ% is the cylinder destruction specified excess pressure barrier. The invention allows producing a cylinder ruling out the gas excess pressure exceeding the tolerable maximum pressure and ensures lower costs of production.

EFFECT: producing a cylinder ruling out the gas excess pressure exceeding the tolerable maximum pressure and ensures lower costs of production.
