An assembly is provided for rotational equipment. This assembly includes a seal carrier, a seal element and a retainer. The seal carrier is configured with a receptacle. The seal element is seated in the receptacle. The retainer is configured to secure the seal element to the seal carrier. The seal element is arranged radially between the seal carrier and the retainer.

Retainer for securing a seal element to a seal carrier

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 rotatable about an axial centerline. The seal land includes a seal land surface. The seal element extends circumferentially around the axial centerline. The seal element includes a seal element surface and a seal element passage. The seal element surface is abutted against and is sealingly engaged with the seal land surface. The seal element passage extends through the seal element to an interface between the seal element surface and the seal land surface.

Rotational equipment seal element with internal fluid passage

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.

Porous seal element with internal fluid passage

A fluid delivery device is provided that includes a sleeve and a tube. The sleeve extends axially along an axis between a sleeve first end and a sleeve second end. The sleeve extends radially from a sleeve inner side to a sleeve outer side. The sleeve extends circumferentially around the axis thereby forming an internal bore at least partially formed by a bore surface at the sleeve inner side. The internal bore extends axially along the axis through sleeve between the sleeve first end and the sleeve second end. The tube is connected to the sleeve and projects out from the sleeve outer side to a tube distal end. The tube is configured with a delivery device fluid passage fluidly coupled with the internal bore. The delivery device fluid passage extends radially through the tube to a fluid passage outlet at the tube distal end.

Translating fluid delivery device

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.

Fluid delivery system for rotational equipment

An assembly is provided for a gas turbine engine. This gas turbine engine assembly includes a pin, a seal support assembly and a seal element. The pin is configured with a pin fluid passage. The seal support assembly is mated with and slidable along the pin. The seal element is mounted to the seal support assembly. The seal element is configured with a seal element fluid passage that is fluidly coupled with the pin fluid passage through the seal support assembly.
