Appropriate seals, such as annular rubber rings, may be interposed between shaft assembly 14 and various portions of the housings. These seals are intended to prevent oil from ?owing from bearing cavities 186 and 202 into the gaseous streams of engine 10. Lubrication of front bearing 220 is accomplished by feeding oil under pressure through passages 222 and 224 respectively located in the center of gear 226 and in front bearing housing 204.
