Abstract

An oil nozzle assembly includes a nozzle body and a nozzle insert. The nozzle body includes a main portion, a tip portion, and a lip. The tip portion is connected to the main portion. The lip extends outwards from the tip portion and has an outer width. The nozzle insert includes a sleeve, an endwall connected to the sleeve, an orifice, and a retention element. The orifice is disposed in the endwall and is fluidly connected to the tip portion of the nozzle body. The retention element extends inward from the sleeve. A portion of the retention element has an inner width that is less than the outer width of the lip. The nozzle insert is disposed onto the tip portion of the nozzle body.

First claim

The invention claimed is:

1. An oil nozzle assembly comprising:
a nozzle body comprising:
a main portion;
a tip portion connected to the main portion;
a lip extending outwards from the tip portion, wherein the lip includes an outer width; and

a nozzle insert comprising:
a sleeve;
an endwall connected to the sleeve;
an orifice disposed in the endwall, wherein the orifice is fluidly connected to the tip portion of the nozzle body;
a retention element extending inward from the sleeve, wherein a portion of the retention element includes an inner width that is less than the outer width of the lip, and further wherein the nozzle insert is disposed onto the tip portion of the nozzle body; and
a plurality of compliant features extending in an axial direction from the sleeve in a direction opposite from the endwall, wherein each of the plurality of compliant features comprises a first portion and a second portion.

2. The oil nozzle assembly of claim 1 further wherein the retention element is positioned further away from an end of the tip portion of the nozzle body that is opposite of the main portion than the lip of the nozzle body.

3. The oil nozzle assembly of claim 2 further wherein the retention element of the nozzle insert engages with the lip of the nozzle body, wherein the lip stops the retention element from displacement in a direction towards the end of the tip portion of the nozzle body.

4. The oil nozzle assembly of claim 3 , wherein the retention element comprises:
a first segment connected to an inner sidewall of the sleeve;
a second segment connected to the first segment, wherein the second segment is longer than the first segment; and
a third segment connected to the second segment, wherein the third segment is shorter than the second segment.

5. The oil nozzle assembly of claim 4 , wherein the tip portion on the nozzle body includes a channel formed by the lip for receiving the retention element of the nozzle insert, and further wherein the second segment of the retention element is positioned in the channel.

6. The oil nozzle assembly of claim 1 , wherein the plurality of compliant features is compressed between a collar of the nozzle body and the sleeve of the nozzle insert.

7. The oil nozzle assembly of claim 1 , wherein the plurality of compliant features exerts a spring force onto a collar of the nozzle body biasing the nozzle insert in a direction towards an end of the tip portion of the nozzle body.
