Abstract
An embodiment coupling device includes a boss disposed at an end of a pressure vessel that is configured to store a target fluid, the boss including an inflow/outflow path through which the target fluid is introduced or discharged and a guide hole disposed in a reference direction orthogonal to a longitudinal direction of the pressure vessel and a manifold member configured to be inserted into the guide hole in the reference direction and including a manifold flow path configured to communicate with the inflow/outflow path.
Claims20
A coupling device comprising:
- a boss disposed at an end of a pressure vessel that is configured to store a target fluid, the boss comprising an inflow/outflow path through which the target fluid is introducible or dischargeable and a guide hole disposed in a reference direction orthogonal to a longitudinal direction of the pressure vessel;
- a manifold member insertable into the guide hole in the reference direction and comprising a manifold flow path configured to communicate with the inflow/outflow path wherein a length of the guide hole is greater than a length of the manifold member in the longitudinal direction;
- a first sealing member disposable between the boss and a surface of the manifold member that faces the inflow/outflow path,
- wherein the first sealing member is configured to be in surface contact with the boss and the surface of the manifold member;
- and
- a blocking member being band shaped and having an arc-shaped cross-section, wherein the blocking member is configured to block a gap between the guide hole and the manifold member in the longitudinal direction.

A coupling device comprising:
- a boss disposed at an end of a pressure vessel that is configured to store a target fluid, the boss comprising an inflow/outflow path through which the target fluid is introducible or dischargeable and a guide hole disposed in a reference direction orthogonal to a longitudinal direction of the pressure vessel;
- a manifold member removably arranged in the guide hole in the reference direction and comprising a manifold flow path communicating with the inflow/outflow path, wherein a length of the guide hole is greater than a length of the manifold member in the longitudinal direction;
- a first sealing member disposed between the boss and a surface of the manifold member that faces the inflow/outflow path, wherein the first sealing member is in surface contact with the boss and the surface of the manifold member;
- a restriction member configured to restrict a movement of the manifold member relative to the boss in the longitudinal direction of the pressure vessel;
- and
- a blocking member being band shaped and having an arc-shaped cross-section, wherein the blocking member blocks a gap between the guide hole and the manifold member in the longitudinal direction.
