Title:
LUBRICATING OIL COOLING DEVICE FOR ON VEHICLE INTERNAL- COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS6085211
Kind Code:
A
Abstract:
PURPOSE:To enable cooling by means of a rationally installed structure by providing a heat exchanger in a cooling water passage between a water jacket and a radiator to carry out heat exchange between engine cooling water and engine lubricating oil. CONSTITUTION:High temperature cooling water from the water jacket of an internal-combustion engine 1 enters a heat exchanger 8 for cooling engine lubricating oil through a filling port member 6 having a cooling water filling port 5, cools engine lubricating oil from an oil pan 26 by means of heat exchange, and is sent to a radiator 12 through a cooling water passage means A. The cooling water cooled in the radiator 12 is sent to a heat exchanger 22 for cooling transmission-gear operating oil through a cooling water passage means B, cools operating oil from a transaxle device 2 by means of heat exchange, and is refluxed to the water jacket. Thereby the engine lubricating oil can be efficiently cooled by means of heat exchangers without need for increasing the number of parts and weight.
