Abstract
There is provided a pressure vessel. The pressure vessel may include a nozzle-boss comprising a neck part including a hollow portion and a flange part extended outward from the neck part, a liner coupled with the nozzle-boss to provide a space filled with a fluid therein, and a sealing part inserted into a lower end of the neck part to prevent a spillage of the fluid via a boundary between the nozzle-boss and the liner by preventing a direct contact between the fluid and the boundary.
Claims17
A pressure vessel comprising:
- a nozzle-boss comprising a neck part including a hollow portion and a flange part extended outward from the neck part;
- a liner coupled with the nozzle-boss to provide a space filled with a fluid therein;
- a sealing part inserted into a lower end of the neck part to prevent a spillage of the fluid via a boundary between the nozzle-boss and the liner by preventing a direct contact between the fluid and the boundary;
- and
- a pressure part inserted into the lower end of the neck part to press the sealing part upwardly in an axial direction,
- wherein the sealing part includes a contact-providing part in contact with the liner and the flange part, and the contact-providing part is projected to fit into an insertion space concavely formed by the flange part and the liner to form a pressure space communicated with the space of the liner, and
- wherein a bottom surface of the sealing part comprises a projection projected toward the pressure part to increase an adhesive force between the sealing part and the pressure part.
