Barbeau, D E

A self contained lubrication system is described for a turbine engine, the turbine engine having a support housing and a drive shaft rotatably mounted to the support housing by a bearing assembly. The lubrication system consists of: a first seal assembly extending between the shaft and the housing at a position axially spaced from one side of the bearing assembly; a second seal assembly extending between the shaft and the housing at a position axially spaced from the other side of the bearing assembly; a sump chamber adapted to contain a lubricant formed in the housing between the seal assemblies; and means contained in the sump chamber for pumping lubricant contained in the sump chamber through the bearing assembly during rotation of the shaft, the pumping means having a radial outer periphery; wherein each seal assembly comprises a resilient O-ring sandwiched between a stationary portion of the housing and a rotating portion of the shaft and wherein the O-rings are spaced radially inwardly from the outer periphery of the lubricant pumping means such that the pumping means pumps fluid away from the O-rings.
