Abstract: A lubrication system for a turbine engine having a main shaft rotatably mounted by a bearing assembly in a support housing is provided in which the turbine fuel is used as the lubricant. The main turbine shaft rotatably drives a fuel pump having its inlet coupled to the fuel source for the turbine engine and having its outlet coupled to outlet passage means formed in the support housing. The passage means, in turn, is fluidly connected to a fuel jet orifice positioned in the support housing to project a high velocity and low flow fuel stream onto the bearing assembly and thereby lubricates and cools the same. After passing through the bearing assembly, the fuel lubricant exhausts through exhaust passage means formed between the turbine and the support housing and is exhausted into the exhaust duct of the turbine engine.
