Abstract
An assembly is provided for rotational equipment. This assembly includes a seal land and a seal element. The seal land extends circumferentially around and is configured to rotate about an axial centerline. The seal element is abutted against and is sealingly engaged with the seal land. The seal element extends circumferentially around the axial centerline. The seal element includes porous material, an exterior surface and a seal element passage. The seal element is configured to flow lubricant from the seal element passage, through the porous material, to the exterior surface.
Claims18
An assembly for rotational equipment, comprising:
- a seal land extending circumferentially around and configured to rotate about an axial centerline;
- a seal element adjacent and sealingly engaged with the seal land, the seal element extending circumferentially around the axial centerline, and the seal element comprising porous material, an exterior surface and a seal element passage, wherein the seal element is configured to flow lubricant from the seal element passage, through the porous material, to the exterior surface;
- a guide rail;
- and
- a seal carrier mated with and translatable along the guide rail;
- the seal element mounted to the seal carrier.
An assembly for rotational equipment, comprising:
