Abstract

An assembly is provided for rotational equipment. This assembly includes a first component, a static structure, a guide rail and a second component. The static structure includes a static structure fluid passage. The guide rail is mounted to the static structure. The guide rail includes a guide rail fluid passage and a nozzle. The guide rail fluid passage fluidly couples the static structure fluid passage to a nozzle orifice of the nozzle. The nozzle is configured to direct fluid onto the first component through the nozzle orifice. The second component is mated with and configured to translate along the guide rail.

First claim

What is claimed is:

1. An assembly for rotational equipment, comprising:
a first component;
a static structure comprising a static structure fluid passage;
a guide rail mounted to the static structure, the guide rail comprising a guide rail fluid passage and a nozzle, the guide rail fluid passage fluidly coupling the static structure fluid passage to a nozzle orifice of the nozzle, and the nozzle configured to direct fluid onto the first component through the nozzle orifice; and
a second component mated with and configured to translate along the guide rail.

2. The assembly of claim 1 , wherein the first component comprises a bearing.

3. The assembly of claim 1 , wherein the first component comprises a seal land.

4. The assembly of claim 1 , wherein the first component comprises a compartment wall.

5. The assembly of claim 1 , wherein the first component includes
an inner race;
an outer race circumscribing the inner race; and
a plurality of bearing elements arranged between and engaged with the inner race and the outer race.

6. The assembly of claim 5 , wherein the nozzle is configured to direct the fluid into a gap between the inner race and the outer race through the nozzle orifice.

7. The assembly of claim 1 , wherein the second component comprises a seal carrier.

8. The assembly of claim 7 , further comprising:
a seal land configured to rotate about an axial centerline; and
a seal element mounted to the seal carrier, the seal element configured to sealingly engage the seal land.

9. The assembly of claim 8 , wherein the seal land is axially adjacent the first component.

10. The assembly of claim 8 , wherein the seal element comprises a carbon seal element.

11. The assembly of claim 7 , further comprising a spring element configured to bias the seal carrier away from the static structure.

12. The assembly of claim 1 , further comprising:
a plurality of guide rails comprising the guide rail, the plurality of guide rails arranged in an array about a centerline; and
the second component mated with and configured to translate along each of the plurality of guide rails.

13. The assembly of claim 1 , wherein the guide rail comprises a hollow pin.

14. The assembly of claim 1 , wherein the guide rail is mounted to the static structure by an interface connection between the guide rail and the static structure.

15. The assembly of claim 1 , wherein
the guide rail extends longitudinally between a guide rail first end and a guide rail second end;
the guide rail is mounted to the static structure at the guide rail first end; and
the nozzle is arranged at the guide rail second end.

16. The assembly of claim 1 , wherein a centerline of the guide rail fluid passage is angularly offset from a centerline of the nozzle orifice by an angle.

17. The assembly of claim 1 , wherein
the rotational equipment comprises a gas turbine engine;
the first component is configured as a first component of the gas turbine engine; and
the second component is configured as a second component of the gas turbine engine.

18. An assembly for rotational equipment, comprising:
a first component;
a static structure;
a guide rail mounted to the static structure, the guide rail comprising a guide rail fluid passage and a nozzle, the nozzle comprising a nozzle orifice fluidly coupled with the guide rail fluid passage, and the nozzle orifice having a nozzle orifice centerline with a trajectory that is coincident with the first component; and
a second component mated with and configured to translate along the guide rail.

19. The assembly of claim 18 , further comprising:
a seal land configured to rotate about an axial centerline; and
a seal element mounted to a seal carrier, the seal element configured to sealingly engage the seal land;
the second component comprising the seal carrier.

20. An assembly for a gas turbine engine, comprising:
a static guide rail comprising a guide rail fluid passage and a nozzle, the nozzle comprising a nozzle orifice fluidly coupled with the guide rail fluid passage, and a centerline of the guide rail fluid passage angularly offset from a centerline of the nozzle orifice by an included angle; and
a seal carrier mated with and configured to translate along the static guide rail.
