Abstract

A piston cooling jet includes a first body and a second body. The first body includes a housing having an inlet fluidly coupled with nozzle outlets. The second body is coupled to the first body to form an interior chamber disposed inside the first body and the second body. The interior chamber is fluidly coupled with the inlet and the nozzle outlets. The interior chamber directs fluid received via the inlet through the nozzle outlets and out of the piston cooling jet assembly in a direction towards a spray target.

First claim

The invention claimed is:

1. A piston cooling jet assembly, comprising:
a first body, the first body comprising a housing having an inlet fluidly coupled with nozzle outlets, wherein the first body further comprises a first mating surface; and
a second body comprising a second mating surface, wherein the second body is coupled to the first body to form an interior chamber disposed inside the first body and the second body, wherein the first mating surface contacts the second mating surface when the first body is coupled to the second body, wherein the interior chamber is fluidly coupled with the inlet and the nozzle outlets, wherein the interior chamber is configured to direct fluid received via the inlet through the nozzle outlets and out of the piston cooling jet assembly in a direction towards a spray target, and wherein at least one of the first mating surface and the second mating surface comprises a leg and a cross-bar, wherein the leg is perpendicular to the cross-bar.

2. The piston cooling jet assembly of claim 1 , wherein the first body and the second body are formed of one or more plastics.

3. The piston cooling jet assembly of claim 1 , wherein the housing, the inlet, and the nozzle outlets of the first body are configured to be integrally formed as a unitary component.

4. The piston cooling jet assembly of claim 1 , further comprising a valve chamber, wherein the valve chamber is configured to receive a valve, wherein the valve is configured to control one or more of an amount of pressure at which the fluid is directed into the inlet or an amount of pressure at which the fluid is directed out of the nozzle outlets.

5. The piston cooling jet assembly of claim 4 , wherein the valve includes a spring and a check ball, wherein the spring and the check ball are configured to be displaced by the fluid received via the inlet.

6. The piston cooling jet assembly of claim 1 , wherein the second body is welded, adhered, or fastened to the first body.

7. The piston cooling jet assembly of claim 1 , wherein the first body includes a mounting bracket that is elongated along and encompasses a mating axis, and wherein the second body includes a mounting bracket that encompasses the same mating axis, wherein the mounting brackets of the first body and second body are configured to removably receive a mating component in order to operably couple the piston cooling jet assembly to the mating component.

8. The piston cooling jet assembly of claim 7 , wherein one or both of the mounting bracket of the first body or the mounting bracket of the second body are configured to removably retain a collar within the one or both of the mounting bracket of the first body or the mounting bracket of the second body.

9. The piston cooling jet assembly of claim 1 , wherein the first body includes one or more recesses, wherein the one or more recesses are configured to one or more of reduce a weight of the first body, add structure to the first body, or provide a uniform cross-section of the first body.

10. The piston cooling jet assembly of claim 1 , wherein the first body includes one or more stiffeners.

11. The piston cooling jet assembly of claim 1 , wherein the nozzle outlets include a first nozzle outlet and a second nozzle outlet, wherein the interior chamber includes a divider configured to control an amount of fluid directed out of the first nozzle outlet and control an amount of fluid directed out of the second nozzle outlet.

12. The piston cooling jet assembly of claim 1 , wherein the first body has a mating surface that has a shape that is substantially common to a shape of a mating surface of the second body, wherein the mating surface of the first body is configured to operably couple to the mating surface of the second body when the second body is operably coupled to the first body.

13. A piston cooling jet assembly, comprising:
a first body, the first body comprising a housing having an inlet fluidly coupled with nozzle outlets by a valve chamber, wherein the valve chamber is configured to receive a check valve; and
a second body coupled to the first body to form an interior chamber disposed inside the first body and the second body, wherein the interior chamber is fluidly coupled with the inlet and the nozzle outlets, wherein the interior chamber is configured to direct fluid received via the inlet through the nozzle outlets and out of the piston cooling jet assembly in a direction towards a spray target,
wherein the housing, the inlet, the nozzle outlets, and the valve chamber of the first body are configured to be integrally formed as a unitary component,
wherein the check valve is configured to control an amount of pressure at which the fluid is directed into the inlet,
wherein the check valve is configured to control an amount of pressure at which the fluid is directed out of the nozzle outlets, and
wherein the first body includes a mounting bracket that is elongated along and encompasses a mating axis, and wherein the second body includes a mounting bracket that encompasses the same mating axis, wherein the mounting brackets of the first body and second body are configured to removably receive a mating component in order to operably couple the piston cooling jet assembly to the mating component.

14. The piston cooling jet assembly of claim 13 , wherein one or both of the mounting bracket of the first body or the mounting bracket of the second body are configured to removably retain a collar within the one or both of the mounting bracket of the first body or the mounting bracket of the second body.

15. The piston cooling jet assembly of claim 13 , wherein the second body is welded, adhered, or fastened to the first body.

16. The piston cooling jet assembly of claim 13 , wherein the first body includes one or more recesses, wherein the one or more recesses are configured to one or more of reduce a weight of the first body, add structure to the first body, or provide a uniform cross-section of the first body.

17. The piston cooling jet assembly of claim 13 , wherein the check valve includes a spring and a check ball, wherein the spring and the check ball are configured to be displaced by the fluid received via the inlet.

18. The piston cooling jet assembly of claim 13 , wherein the first body includes one or more stiffeners.

19. The piston cooling jet assembly of claim 13 , wherein the nozzle outlets include a first nozzle outlet and a second nozzle outlet, wherein the interior chamber includes a divider configured to control an amount of fluid directed out of the first nozzle outlet and control an amount of fluid directed out of the second nozzle outlet.

20. The piston cooling jet assembly of claim 13 , wherein the first body has a mating surface that has a shape that is substantially common to a shape of a mating surface of the second body, wherein the mating surface of the first body is configured to operably couple to the mating surface of the second body when the second body is operably coupled to the first body.
