In combination with an internal combustion engine, a device for the purification of lubricating oil. Installed as a bypass between the outlet side of the oil pump and the crankcase, the device refines contaminated oil by boiling off under a suitable temperature range condition, contaminants such as condensed water, diluted fuel, and products resulting from partial decomposition vice comprises a closed chamber (2) admitting oil under pressure at the bottom of the chamber (2). The oil is forced through a maze formed by a stack of circular vanes (17) before exiting near the top of the chamber (2) and being returned to the crankcase. An electrical heating element (11) under control of a thermostat (13) heats the vanes (17) to a temperature necessary to boil off the contaminants. The vaporized contaminants can escape through a vent (23) in the top portion of the chamber (2). |
