Abstract

A pressure vessel includes: a barrel part disposed in a predefined square area and having a diameter corresponding to a length of one side of the square area; a first nozzle member disposed at one end of the barrel part; a second nozzle member disposed at an opposite end of the barrel part; and clamp rings disposed in the square area, positioned outside the barrel part, and configured to lock the first and second nozzle members to the barrel part, thereby improving spatial utilization and a degree of design freedom.

First claim

What is claimed is:

1 . A pressure vessel comprising:
a barrel part disposed in a predefined square area and having a diameter corresponding to a length of one side of the square area; a first nozzle member disposed at one end of the barrel part; a second nozzle member disposed at an opposite end of the barrel part; and clamp rings disposed in the square area, positioned outside the barrel part, and configured to lock the first and second nozzle members to the barrel part.

2 . The pressure vessel of claim 1 , wherein each of the clamp rings comprises:
a first side clamp part supported on the first nozzle member; a second side clamp part supported on the second nozzle member; and a connection clamp part configured to continuously connect the first and second side clamp parts.

3 . The pressure vessel of claim 2 , further comprising:
first seating portions protruding from lateral surfaces of the first nozzle member and configured to allow the first side clamp parts to be seated thereon; and second seating portions protruding from lateral surfaces of the second nozzle member and configured to allow the second side clamp parts to be seated thereon.

4 . The pressure vessel of claim 3 , wherein the first and second seating portions each have a semicircular shape, the first side clamp part is in close contact with the first seating portion, and the second side clamp part is in close contact with the second seating portion.

5 . The pressure vessel of claim 3 , further comprising:
first side plates coupled to the first seating portions and configured to cover lateral sides of the first side clamp parts; and second side plates coupled to the second seating portions and configured to cover lateral sides of the second side clamp parts.

6 . The pressure vessel of claim 1 , wherein the square area is provided in plural, the plurality of square areas is disposed adjacent to one another to define a matrix, and the barrel parts are respectively provided in the square areas.

7 . The pressure vessel of claim 6 , wherein the square areas are arranged to define a one-dimensional matrix or a two-dimensional matrix.

8 . The pressure vessel of claim 6 , further comprising:
coupling holes respectively provided in the adjacent first nozzle members; and a coupling member having one end coupled to any one of the adjacent first nozzle members and an opposite end coupled to other of the adjacent first nozzle members.

9 . The pressure vessel of claim 6 , further comprising:
a guide protrusion provided on any one of the adjacent second nozzle members; and a guide groove provided in other of the adjacent second nozzle members and configured to accommodate the guide protrusion so that the guide protrusion is slidable in a longitudinal direction of the barrel part.

10 . The pressure vessel of claim 6 , further comprising:
a connection member configured to integrally connect the adjacent first nozzle members.

11 . The pressure vessel of claim 6 , further comprising:
a spacer interposed between the adjacent first nozzle members and between the adjacent second nozzle members; and an intermediate clamp ring disposed between the adjacent barrel parts and configured to partially surround the adjacent first nozzle members, the spacer, and the adjacent second nozzle members.

12 . The pressure vessel of claim 1 , further comprising:
a sealing part configured to seal a gap between the barrel part and at least one of the first or second nozzle members.

13 . The pressure vessel of claim 12 , wherein the sealing part comprises:
a first sealing member configured to seal the gap; and a second sealing member disposed adjacent to the first sealing member and configured to seal the gap.

14 . The pressure vessel of claim 1 , wherein at least one of the first or second nozzle members comprises:
a nozzle body; and a nozzle cover configured to be movable in a longitudinal direction of the barrel part relative to the nozzle body, and wherein the clamp rings are supported on the nozzle cover.

15 . The pressure vessel of claim 1 , wherein the clamp ring is made of at least one of reinforcing fiber, thermosetting resin, or thermoplastic resin.

16 . The pressure vessel of claim 1 , wherein the clamp ring is provided by winding reinforcing fiber to partially surround the first and second nozzle members in a state in which the first and second nozzle members are coupled to two opposite ends of the barrel part.

17 . The pressure vessel of claim 1 , wherein the clamp ring is assembled to partially surround the first and second nozzle members in a state in which the first and second nozzle members are coupled to two opposite ends of the barrel part.

18 . The pressure vessel of claim 1 , wherein the diameter of the barrel part is determined as a value between a maximum diameter when the barrel part is maximally expanded immediately before the barrel part bursts and a minimum diameter when the barrel part is in a non-expanded state.

19 . The pressure vessel of claim 1 , wherein the barrel part comprises:
a liner having a storage space therein; and a reinforcing layer configured to surround an outer peripheral surface of the liner, and wherein the reinforcing layer is made of at least one of reinforcing fiber, thermosetting resin, or thermoplastic resin.

20 . The pressure vessel of claim 19 , comprising:
reinforcing members disposed between the barrel part and the clamp rings, wherein the reinforcing member has an accommodation groove that accommodates the clamp ring.
