Abstract

A water injector assembly includes an injector body having a substantially hollow interior. The injector body defines an inlet opening defined within an outer radial surface of the injector body at a first axial location along the injector body. The injector body defines a flowpath opening in fluid communication with the inlet opening such that the flowpath opening is configured to receive the fluid from the inlet opening. The injector body defines an outlet opening defined within the injector body at a second axial location along the injector body. The outlet opening is in fluid communication with the flowpath opening, such that the outlet opening receives the fluid from the flowpath opening. The second axial location of the outlet opening is different than the first axial location of the inlet opening.

First claim

What is claimed is:

1. A water injector assembly, comprising:
an injector body having a longitudinal axis extending between a first end and a second end with a substantially hollow interior, the injector body defining:
engagement portions comprising a first engagement portion and a second engagement portion, the first engagement portion set longitudinally inwardly from the first end and closer to the second end than the first end, the second engagement portion spaced apart longitudinally from the first engagement portion toward the second end, the injector body having a diameter at the engagement portions that is larger than the diameter proximate the first end and forming an exterior groove that circumscribes the injector body at each of the first engagement portion and the second engagement portion;
an inlet opening disposed between the exterior groove of first engagement portion and the exterior groove of the second engagement portion, the inlet opening defined within an outer radial surface of the injector body, the inlet opening having an inlet cross-sectional size and being configured to receive a fluid;
a flowpath opening in fluid communication with the inlet opening such that the flowpath opening is configured to receive the fluid from the inlet opening, the flowpath opening extending axially within the injector body, the flowpath opening having a flowpath cross-sectional size that is different than the inlet cross-sectional size; and
an outlet opening defined within the injector body at a second axial location along the injector body, the outlet opening in fluid communication with the flowpath opening, such that the outlet opening is configured to receive the fluid from the flowpath opening, wherein the second axial location of the outlet opening is different than the first axial location of the inlet opening,

wherein the diameter of the injector body at the engagement portions is larger than the diameter of the injector body between the engagement portions.

2. The water injector assembly of claim 1 , wherein the flowpath cross-sectional size is less than the inlet cross-sectional size.

3. The water injector assembly of claim 1 , wherein the flowpath opening extends longitudinally within the injector body substantially parallel to the longitudinal axis.

4. The water injector assembly of claim 1 , wherein the inlet opening extends into the injector body at an angle with respect to the longitudinal axis.

5. The water injector assembly of claim 4 , wherein the angle is non-perpendicular with respect to the longitudinal axis.

6. The water injector assembly of claim 1 , wherein the second axial location is disposed between the second engagement portion and the second end.

7. The water injector assembly of claim 1 , wherein the first engagement portion forms a shoulder, and wherein the inlet opening is formed in the shoulder.

8. A water injector assembly comprising: an injector body having a longitudinal axis extending between a first end and a second end with a substantially hollow interior, the injector body defining: engagement portions comprising a first engagement portion and a second engagement portion, the first engagement portion set longitudinally inwardly from the first end and closer to the second end than the first end, the second engagement portion spaced apart longitudinally from the first engagement portion toward the second end, the injector body having a diameter at the engagement portions that is larger than the diameter proximate the first end and forming an exterior groove that circumscribes the injector body at each of the first engagement portion and the second engagement portion; an inlet opening disposed between the exterior groove of first engagement portion and the exterior groove of the second engagement portion, the inlet opening defined within an outer radial surface of the injector body, the inlet opening having an inlet cross-sectional size and being configured to receive a fluid; a flowpath opening in fluid communication with the inlet opening such that the flowpath opening is configured to receive the fluid from the inlet opening, the flowpath opening extending axially within the injector body, the flowpath opening having a flowpath cross-sectional size that is different than the inlet cross-sectional size; an outlet opening defined within the injector body at a second axial location along the injector body, the outlet opening in fluid communication with the flowpath opening, such that the outlet opening is configured to receive the fluid from the flowpath opening, wherein the second axial location of the outlet opening is different than the first axial location of the inlet opening; and a gasket disposed in the exterior groove of the first engagement portion, wherein the diameter of the injector body at the engagement portions is larger than the diameter of the injector body between the engagement portions.

9. The water injection assembly of claim 8 , wherein the first engagement portion forms a shoulder, and wherein the inlet opening is formed in the shoulder.

10. The water injector assembly of claim 8 , wherein the flowpath cross-sectional size is less than the inlet cross-sectional size.

11. The water injector assembly of claim 8 , wherein the flowpath opening extends longitudinally within the injector body substantially parallel to the longitudinal axis.

12. The water injector assembly of claim 8 , wherein the inlet opening extends into the injector body at an angle with respect to the longitudinal axis.

13. The water injector assembly of claim 12 , wherein the angle is non-perpendicular with respect to the longitudinal axis.

14. The water injector assembly of claim 8 , wherein the second axial location is disposed between the second engagement portion and the second end.

15. A water injector assembly comprising: an injector body having a longitudinal axis extending between a first end and a second end with a substantially hollow interior, the injector body defining: engagement portions comprising a first engagement portion and a second engagement portion, the first engagement portion set longitudinally inwardly from the first end and closer to the second end than the first end, the second engagement portion spaced apart longitudinally from the first engagement portion toward the second end, the injector body having a diameter at the engagement portions that is larger than the diameter proximate the first end and forming an exterior groove that circumscribes the injector body at each of the first engagement portion and the second engagement portion; an inlet opening disposed between the exterior groove of first engagement portion and the exterior groove of the second engagement portion, the inlet opening defined within an outer radial surface of the injector body, the inlet opening having an inlet cross-sectional size and being configured to receive a fluid; a flowpath opening in fluid communication with the inlet opening such that the flowpath opening is configured to receive the fluid from the inlet opening, the flowpath opening extending axially within the injector body, the flowpath opening having a flowpath cross-sectional size that is different than the inlet cross-sectional size; an outlet opening defined within the injector body at a second axial location along the injector body, the outlet opening in fluid communication with the flowpath opening, such that the outlet opening is configured to receive the fluid from the flowpath opening, wherein the second axial location of the outlet opening is different than the first axial location of the inlet opening; and a gasket disposed in the ex
