HIGH-PRESSURE CYLINDER Russian patent published in 2008 - IPC F17C1/06 

FIELD: mechanics.

SUBSTANCE: high-pressure cylinder is intended for keeping fluids and gases in motor vehicles using a gas fuel, as well as fluids and fire-extinguishing gases in stationary fire-extinguishing modules. The cylinder incorporates a seamless inner all-metal sealing enclosure (1) and out strengthening element (2) made up of two multi-layer coverings (3, 4). Composite material of coverings (3, 4) is made up proceeding from the following expression, i.e. δ_B1<δ_B2, E₁<E₂, where δ_B1 and δ_B2 are the first (inner) and the second (outer) coverings composite material breaking point, respectively, E₁ and E₂ are the first (inner) and the second (outer) coverings composite material coefficient of elasticity, respectively.

EFFECT: higher reliability, cyclic strength at a high destructive pressure, longer life, lower weight and smaller sizes.
