Patent ID: 6893208

Claim:
A discharge system for a gas generator including an axial air compressor driven by a gas turbine with a plurality of blades, said compressor and said turbine blades being installed on a common shaft supported by journal bearings including a first bearing located at an inlet to the compressor and a second bearing located between said axial compressor and said turbine, at least one of said bearings being received within a sleeve, said shaft being surrounded by a plurality of supporting means fixed to a housing defining, in part, lateral sump chambers about the bearings, piping for delivery and discharging lubricating and cooling fluid relative to bearing surfaces of said one bearing, said sump chambers receiving a first amount of said lubricating fluid by gravity for flow through said discharge piping, means defining a space about the bearing sleeve having a said second amount of fluid subjected to a differential pressure relative to the pressure of the first fluid existing in said sump chambers, and a plurality of floating seals at the ends of said one bearing creating said differential pressure.
