ABSTRACT:
A hermetically sealed hydraulic power supply having an oil reservoir with a pump for pumping oil from the reservoir which is driven by a gas turbine. The gas turbine has a turbine cavity and fluid inlet and exhaust passages communicating therewith. A pair of burst discs are positioned to block the turbine cavity and a quantity of oil fills the turbine cavity and extends to the burst discs to isolate the oil reservoir from the environment and preclude the existence of any space to which reservoir oil could leak. A bellows is positioned to permit thermal expansion and contraction of the oil sealed in the turbine cavity by the burst discs.
