Title:
高圧タンク
Document Type and Number:
Japanese Patent JP4077636
Kind Code:
B2
Abstract:
A high-pressure tank in which the sealing ability and pressure-proof strength at a mouth portion are prevented from being lower by a high pressure within the tank, wherein the mouth portion 2 projects into the inside of the tank, and internal threads are formed on an inner peripheral surface of the mouth portion, and a thread member is threadedly engaged with the internal threads. Further, a seal member is provided between the mouth portion and the thread portion, and is disposed adjacent to the inner peripheral surface of the mouth portion adjacent to an inner end thereof disposed within the tank. A high pressure within the tank acts on an outer peripheral surface of the mouth portion while the atmospheric pressure acts on the inner peripheral surface of the mouth portion, so that the mouth portion is compressed radially inwardly, thereby preventing the loosening of the tightened seal member.
