  • Ebullient cooled turbocharger bearing housing
    Patent number: 4107927
    Abstract: A turbocharged internal combustion engine system including a liquid-cooled internal combustion engine, a heat exchanger for cooling the liquid, a pump for pumping cooled liquid from the heat exchanger to the engine, and a turbocharger including a rotary turbine and a rotary compressor, a housing containing the turbine and the compressor, a shaft interconnecting the turbine and the compressor and bearings journalling the shaft within the housing between the turbine and compressor. Exhaust gases from the engine are directed through the turbine to drive the same and air from the compressor is directed to the engine. A liquid passage is located in the turbocharger housing and is operatively interposed between the turbine and the bearing. The passage has a lower inlet and an upper outlet and liquid coolant from the engine is directed to the inlet.
    Type: Grant
