Abstract

A fluid tank that includes a housing. The housing includes a bottom wall, a top wall, and a side wall. The side wall couples the bottom wall to the top wall to define a cavity that receives and houses a liquid. A conduit guides liquid from a fluid source into the cavity. The conduit defines an inlet and an outlet. The outlet couples to the side wall. A vent coupled to the housing and to the conduit. The vent defines a vent inlet coupled to the housing and a vent outlet coupled to the conduit. The vent discharges gas from the housing into the conduit.

First claim

The invention claimed is:

1. A fluid tank, comprising:
a housing comprising:
a bottom wall;
a top wall; and
a side wall coupling the bottom wall to the top wall to define a cavity that receives and houses a liquid;

a conduit configured to guide the liquid from a fluid source into the cavity, the conduit defines an inlet and an outlet, wherein the outlet couples to the side wall; and
a vent coupled to the housing and to the conduit, wherein the vent defines a vent inlet coupled to the housing and a vent outlet coupled to the conduit, and wherein the vent is configured to discharge gas from the housing into the conduit;
wherein the vent comprises an inlet portion and a vent conduit portion, the vent inlet is positioned at the inlet portion, the inlet portion comprises a first inlet baffle and a second inlet baffle, and the first inlet baffle and the second inlet baffle overlap in a first direction and are offset in a second direction.

2. The fluid tank of claim 1 , comprising a cap configured to couple to the inlet of the conduit to block a flow of the liquid into and the gas out of the fluid tank.

3. The fluid tank of claim 1 , wherein the vent couples to the top wall.

4. The fluid tank of claim 1 , wherein the inlet portion is angled relative to the vent conduit portion.

5. The fluid tank of claim 1 , wherein the vent comprises an outlet portion, and wherein the outlet portion is angled relative to the vent conduit portion.

6. The fluid tank of claim 5 , wherein the outlet portion comprises a first outlet baffle and a second outlet baffle.

7. The fluid tank of claim 6 , wherein the first outlet baffle and the second outlet baffle overlap in a third direction and are offset in a fourth direction.

8. The fluid tank of claim 1 , wherein the vent couples to the side wall.

9. The fluid tank of claim 1 , wherein the vent defines a central axis, and wherein the central axis is parallel to the top wall.

10. The fluid tank of claim 1 , wherein the vent defines a central axis, and wherein the central axis is perpendicular to the side wall.

11. The fluid tank of claim 1 , wherein the vent defines a central axis, and wherein the central axis forms an obtuse angle with the side wall.

12. A fluid tank, comprising:
a housing comprising:
a bottom wall;
a top wall; and
a side wall coupling the bottom wall to the top wall to define a cavity that receives and houses a liquid;

a conduit configured to guide the liquid from a fluid source into the cavity, the conduit defines a conduit inlet and a conduit outlet, wherein the conduit outlet couples to the side wall; and
a vent having a first portion and a second portion, wherein the first portion extends through the conduit, the second portion extends into the housing, the second portion couples to an interior surface of the side wall and extends upwardly from the first portion along the side wall toward the top wall, and the vent is configured to discharge gas from the housing through the conduit.

13. The fluid tank of claim 12 , wherein the vent defines a vent inlet and a vent outlet.

14. The fluid tank of claim 13 , wherein the vent outlet is flush with the conduit inlet.

15. The fluid tank of claim 12 , wherein the vent defines a first cross-sectional area the conduit defines a second cross-sectional area, and the second cross-sectional area is greater than the first cross-sectional area.

16. The fluid tank of claim 13 , wherein a distance between the vent outlet and an interior surface of the top wall is less than ten percent of a height of the side wall.

17. A fluid tank, comprising:
a housing comprising:
a bottom wall;
a top wall; and
a side wall coupling the bottom wall to the top wall to define a cavity that receives and houses a liquid;

a conduit configured to guide the liquid from a fluid source into the cavity, wherein the conduit extends between a conduit inlet opening and a conduit outlet opening, and the conduit couples to the housing; and
a vent extending through the conduit and configured to discharge gas from the housing through the conduit, wherein the vent extends between a vent inlet opening and a vent outlet opening, and the vent outlet opening is flush with the conduit inlet opening.

18. The fluid tank of claim 17 , comprising a cap configured to selectively cover the vent outlet opening and the conduit inlet opening.

19. The fluid tank of claim 17 , wherein a distance between the vent outlet opening and an interior surface of the top wall is less than ten percent of a height of the side wall.

20. The fluid tank of claim 17 , wherein the vent defines a first cross-sectional area, the conduit defines a second cross-sectional area, and the second cross-sectional area is greater than the first cross-sectional area.
