SUBSTANCE: invention relates to a pressure accumulator comprising a cylindrical housing made of metal and adapted for evaporation and storage of liquefied gas in a storage space available in the cylindrical housing. Accumulator includes a cover having a through hole allowing the pipe to pass through the through hole. Cover is adapted to fix the pipe passing through the through hole and to close the opening end of the cylindrical housing with a gap between the cover and the inner peripheral surface of the cylindrical housing. Gap communicates with the cylindrical housing storage space. Besides, there is a sealing structure between the outer peripheral part of the cover and the inner peripheral part of the cylindrical housing, which fills part of the gap, and a fastening element located at the opening end of the cylindrical housing. Besides, outer peripheral surface of fastener is connected by thread with inner peripheral surface of cylindrical housing for support and fixation of cover from external side of cover.

EFFECT: possibility to evaporate and store liquefied gas without causing brittle destruction of cylindrical reservoir.
