Abstract: A bearing is mounted to a static structure outwardly of the shaft, and supporting the shaft. A bearing compartment is defined by face seal arrangements on each of two axial sides of a bearing. Each face seal arrangement includes a seal seat rotating with the shaft and a non-rotating sealing ring. The seal housing is exposed to high pressure air outward of the bearing compartment. A coil spring biases the seal housing towards the seal seat, such that the sealing face is biased into contact with the seal seat by a bias force including a net fluid force acting on the seal housing and the coil spring. The sealing face is defined by a contact portion contacting the seal seat and a feed portion recessed from the seal seat. The feed portion includes a plurality of circumferentially spaced feed slots fluidly connected to at least one annular groove.

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.

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 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.

Abstract: 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.
