Title:
HIGH-PRESSURE VESSEL
Document Type and Number:
Japanese Patent JP2019158005
Kind Code:
A
Abstract:
To obtain a high-pressure vessel which can maintain airtightness.SOLUTION: At least a part of a reinforcing member 32B constituted of metal is arranged in a seal member 32. Therefore, when a load is applied to the seal member 32 by the displacement of a mouthpiece 22, the large deformation of the seal member 32 is suppressed by the reinforcing member 32B, and the deformation of the seal member 32 can be suppressed. In the seal member 32, a cross section shape of the seal member 32 orthogonal to a peripheral direction is formed into a substantially-C shape which is opened toward the inside of an axial direction. Accordingly, when the pressure of fluid in a flank part 14 is increased, the fluid acts so as to press the seal member 32 to the outside of the axial direction, however, the substantially-C-shaped reinforcing member 32B which is opened toward the inside of the axial direction at this time is elastically deformed so as to press a first abutment wall part 32BC and a base end part 32AA of the seal member 32 to the flank part 14 side and the mouthpiece 22 side. By this constitution, airtightness can be maintained.SELECTED DRAWING: Figure 4
