Abstract

A fuel-water separator includes a cartridge assembly and a bowl. The cartridge assembly receives a fuel-water mixture and provides a fuel. The cartridge assembly includes an endplate. The bowl is configured to store water separated from the fuel-water mixture. The bowl is coupled to the endplate. The endplate includes an air vent that receives air from the bowl. The air vent establishes a pressure equilibrium within the bowl and the cartridge assembly.

First claim

What is claimed is:

1. A fuel-water separator configured to facilitate separation of a fuel from a fuel-water mixture, the fuel-water separator comprising:
a cartridge assembly comprising an endplate comprising:
a top side;
a bottom side;
an axial body;
a first radial rib extending radially from the axial body along the bottom side;
a second radial rib extending radially from the axial body along the bottom side;
an air vent extending through the axial body in a generally radial direction between the first radial rib and the second radial rib; and
a first circumferential rib including a first portion that extends circumferentially along the bottom side, the first portion radially separated from the first radial rib, the first portion cooperating with the axial body, the first radial rib, and the second radial rib so to provide a first flow path to the air vent; and

a bowl coupled to the bottom side and configured to store water separated from the fuel-water mixture.

2. The fuel-water separator of claim 1 , wherein:
the endplate further comprises a third radial rib extending radially from the axial body along the bottom side;
the first radial rib extends between the third radial rib and the air vent; and
the first flow path is communicable with a region between the first radial rib and the third radial rib.

3. The fuel-water separator of claim 1 , wherein the endplate further comprises a second circumferential rib including a second portion that extends circumferentially along the bottom side, the second portion radially separated from the second radial rib, the second portion cooperating with the axial body, the second radial rib, and the second radial rib so to provide a second flow path to the air vent.

4. The fuel-water separator of claim 1 , wherein the cartridge assembly further comprises a coalescing tube, and the axial body is received within the coalescing tube.

5. The fuel-water separator of claim 1 , wherein:
the bowl comprises:
a central body received within the axial body; and
a circumferential body disposed about the central body, the circumferential body cooperating with the endplate to define a circumferential cavity therebetween; and

the air vent is communicable with the circumferential cavity.

6. The fuel-water separator of claim 5 , wherein:
the central body defines a central cavity; and
the bowl comprises:
an outlet channel communicable with the central cavity; and
an inlet channel communicable with the circumferential cavity.

7. The fuel-water separator of claim 6 , further comprising a drain plug, and wherein:
the bowl further comprises a drain plug aperture;
the drain plug is positioned within the drain plug aperture; and
the drain plug fluidly couples the outlet channel and the inlet channel such that the central cavity is fluidly coupled to the circumferential cavity.

8. The fuel-water separator of claim 6 , further comprising a sensor, the sensor positioned within a sensor aperture defined in the bowl.

9. The fuel-water separator of claim 8 , wherein:
the sensor aperture is disposed proximate the circumferential cavity; and
the sensor is configured to determine an amount of the water stored within the bowl.

10. A fuel-water separator configured to facilitate separation of a fuel from a fuel-water mixture, the fuel-water separator comprising:
a cartridge assembly comprising an endplate comprising:
a top side;
a bottom side;
an axial body;
a first radial rib extending radially from the axial body along the bottom side;
a second radial rib extending radially from the axial body along the bottom side;
a first air vent extending through the axial body in a generally radial direction between the first radial rib and the second radial rib; and
a first circumferential rib coupled to the first radial rib, the first circumferential rib including a first portion extending towards the second radial rib; and

a bowl coupled to the bottom side and configured to store water separated from the fuel-water mixture.

11. The fuel-water separator of claim 10 , wherein:
the endplate further comprises:
a third radial rib extending radially from the axial body along the bottom side; and
a second air vent extending through the axial body between the second radial rib and the third radial rib;

the first radial rib extends between the third radial rib and the first air vent; and
the second radial rib extends between the first radial rib and the second air vent.

12. The fuel-water separator of claim 10 , wherein the endplate further comprises a second circumferential rib coupled to the second radial rib, the second circumferential rib including a second portion extending towards the first radial rib.

13. The fuel-water separator of claim 12 , wherein:
the endplate further comprises a circumferential wall segment coupled to the first circumferential rib and the second circumferential rib; and
a portion of the bottom side is bordered by the axial body, the first radial rib, the first circumferential rib, the second radial rib, the second circumferential rib, and the circumferential wall segment.

14. The fuel-water separator of claim 10 , wherein:
the bowl comprises:
a central body received within the axial body; and
a circumferential body disposed about the central body, the circumferential body configured to cooperate with the endplate to define a circumferential cavity therebetween; and

the first air vent is communicable with the circumferential cavity.

15. The fuel-water separator of claim 10 , wherein the first radial rib is centered on the first circumferential rib.

16. The fuel-water separator of claim 10 , wherein the first circumferential rib includes a second portion contiguous with the first portion, the second portion extending towards the axial body.

17. A fuel-water separator configured to facilitate separation of a fuel from a fuel-water mixture, the fuel-water separator comprising:
a cartridge assembly comprising an endplate comprising:
a top side;
a bottom side;
an axial body;
a first radial rib extending radially from the axial body along the bottom side;
a second radial rib extending radially from the axial body along the bottom side;
an air vent extending through the axial body in a generally radial direction, and the first radial rib disposed between the air vent and the second radial rib;
a first circumferential rib coupled to the first radial rib, the first circumferential rib including a first portion extending towards the second radial rib; and
a second circumferential rib coupled to the second radial rib, the second circumferential rib including a second portion extending towards the first radial rib; and
