  • Lubricating system
    Patent number: 5220892
    Abstract: A differential pressure valve 6 is provided in an engine lubricating system which spills lubricating oil into a bypass line 5b bypassing a lubricating oil heat exchanger 7. Connected downstream of the differential pressure valve 6, is a pressure-maintaining valve 10, which holds the oil pressure approximately constant when the internal-combustion engine is running and protects the lubricating oil pump against too high a pressure upon starting of a cold internal-combustion engine.
