Abstract

A fluid storage and delivery apparatus may include a fluid container, a first apparatus component, and a housing. One or more support members may be coupled to the housing and configured to secure the first apparatus component physically separate from the fluid container. The first apparatus component may be indirectly coupled to the fluid container by one or more coupling members at least partially defining a fluid passageway between the first apparatus component and the fluid container.

Claims

1. A fluid storage and delivery apparatus, comprising:

a fluid container;

a vent valve; and

a housing including a first housing portion and a second housing portion, the first housing portion including one or more vent valve support ribs for supporting the vent valve;

wherein the second housing portion defines a vent valve opening; and

wherein a first portion of the vent valve is secured physically separate from the fluid container by the one or more vent valve support ribs and a second portion of the vent valve extends through the vent valve opening when the first and second housing portions are assembled together.

2. An apparatus according to claim 1, wherein the fluid container is configured for storing liquid oxygen and delivering gaseous oxygen.

3. An apparatus according to claim 1, further comprising:

a fill port for filling the fluid container;

the first housing portion further including one or more fill port support ribs for supporting the fill port;

wherein assembling the first and second housing portions together defines a fill port opening; and

wherein a first portion of the fill port is secured physically separate from the fluid container by the one or more fill port support ribs and a second portion of the fill port extends through the fill port opening defined by the assembled first and second housing portions.

4. An apparatus according to claim 3, wherein:

the fill port includes a first portion having a first shape and a second portion having a second shape different from the first shape; and

the one or more fill port support ribs comprise at least one first rib shaped to receive the first portion of the fill port and at least one second rib shaped to receive the second portion of the fill port.

5. An apparatus according to claim 1, further comprising:

an economizer valve for regulating the pressure of fluid within fluid container; and

one or more economizer valve support ribs coupled to the first housing portion for supporting the economizer valve.

6. An apparatus according to claim 1, wherein the first housing portion further includes support ribs configured to secure a fill port and an economizer valve physically separate from the fluid container.

7. An apparatus according to claim 1, wherein at least one of the vent valve support ribs is formed integrally with the housing.

8. An apparatus according to claim 1, wherein at least one of the vent valve support ribs is shaped to match a contour of the vent valve.

9. An apparatus according to claim 1, further comprising one or more coupling members at least partially defining a fluid passageway between the vent valve and the fluid container, wherein the one or more coupling members are flexible to provide dampening between the vent valve and the fluid container.

10. An apparatus according to claim 1, wherein the second housing portion includes one or more second vent valve support ribs configured to cooperate with one or more first vent valve support ribs to secure the vent valve physically separate from the fluid container.

11. An apparatus according to claim 1, wherein:

the second housing portion includes one or more vent valve support ribs for supporting the vent valve; and

wherein the first portion of the vent valve is secured physically separate from the fluid container by the one or more vent valve support ribs of the first housing portion and by the one or more vent valve support ribs of the second housing portion.

12. A housing for a fluid storage and delivery apparatus, comprising:

a first housing portion and a second housing portion configured, when assembled together, to at least partially house multiple components of the fluid storage and delivery apparatus;

one or more first support ribs coupled to the first housing portion; and

one or more second support ribs coupled to the second housing portion;

wherein assembling the first housing portion with the second housing portion defines an opening between the first and second housing portions, wherein a first one of the components extends through the opening; and

wherein the one or more first support ribs cooperate with the one or more second support ribs to secure the first component physically separate from a second one of the components, the first and second components being indirectly coupled to each other by one or more coupling members at least partially defining a fluid passageway between the first and second components.

13. A housing according to claim 12, wherein the fluid storage and delivery apparatus comprises a liquid oxygen storage and delivery apparatus for storing liquid oxygen and delivering gaseous oxygen.

14. A housing according to claim 12, wherein:

the second component comprises a container for storing a pressurized liquid;

the first component comprises a fill port for filling the container; and

the one or more coupling members comprise tubing for communicating liquid from the fill port into the container.

15. A housing according to claim 14, wherein:

the fill port includes a first portion having a first shape and a second portion having a second shape different from the first shape; and

the one or more first support ribs comprise a first portion shaped to receive the first portion of the fill port and a second portion shaped to receive the second portion of the fill port.

16. A housing according to claim 12, wherein the one or more support members are configured to secure a fill port, a vent valve, and an economizer valve physically separate from a fluid container.

17. A housing according to claim 12, wherein at least one of the first support ribs is formed integrally with the first housing portion, and at least one of the second support ribs is formed integrally with the second housing portion.

18. A housing according to claim 12, wherein at least one of the first support ribs is shaped to match a contour of the first component.

19. A housing according to claim 12, wherein the one or more coupling members are flexible to provide dampening between the first component and the second component.

20. A fluid storage and delivery apparatus, comprising:

means for storing a fluid;

means for communicating at least a portion of the fluid to or from the fluid storage means; and

means for at least partially housing the fluid storage means and the fluid communication means, including a first housing means portion and a second housing means portion, the first housing means portion including one or more support ribs for supporting the fluid communication means;

wherein assembling the first and second housing means portions together defines an opening; and

wherein a first portion of the fluid communication means is secured physically separate from the fluid storage means at least by the one or more support ribs and a second portion of the fluid communication means extends through the opening defined by the assembled first and second housing means portions.

21. An apparatus according to claim 20, wherein the fluid communication means comprises a fill port.
