HIGH PRESSURE TANK
Document Type and Number:
Japanese Patent JP2018155335
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high pressure tank which can inhibit a fluid from accumulating between an outer surface of a liner and a reinforcement layer and effectively improve the durability of the linear with a simple structure.SOLUTION: A high pressure tank 10 includes: a resin liner 14 which can store a fluid therein; a reinforcement layer 12 covering an outer surface of the liner 14; and a mouth piece 16 which is formed with a supply/discharge hole 32 for supplying/discharging the fluid to/from the liner 14. The mouth piece 16 is further formed with a gas drainage passage 64 having a first opening 60, which opens to a mouth piece facing surface 26 of the liner 14, at one end and a second opening 62, which opens to at least one of the inner side of the supply/discharge hole 32 and the outer side of the reinforcement layer 12, at the other end. A cross section area of the one end side of the gas drainage passage 64 that is orthogonal to an extension direction and an area of the first opening 60 are smaller than a cross section area of the other portion of the gas drainage passage 64 that is orthogonal to the extension direction.SELECTED DRAWING: Figure 2
