초록

An air turbine starter with an improved seal assembly is provided. A fluid conduit or channel allows higher pressure fluid into one side of a bearing seal. For example, the seal assembly may include a face seal, and a second seal forming a chamber therebetween and a flow passage opens into the chamber for exposing the chamber to the higher pressure.

An air turbine starter with an improved seal assembly is provided. A fluid conduit or channel allows higher pressure fluid into one side of a bearing seal. For example, the seal assembly may include a face seal, and a second seal forming a chamber therebetween and a flow passage opens into the chamber for exposing the chamber to the higher pressure. the hole in the fragile part is a blind hole. 6. The apparatus of claim 1, further comprising a second part fixed adjacent the surface of the fragile part at least partially via the expandable bolt device. 7...
