ABSTRACT:
A cooler and filter assembly (2) is disclosed including a cooler housing (4) containing an elongated internal cavity (14) opening into generally planar end faces (16 and 18) of the cooler housing (4) and further including a support structure (6) for mounting the cooler housing (4) on an internal combustion engine and for providing internal supply and return passages (104, 106, 108 and 110) for both engine coolant and lubrication oil through only one of the planar end faces (16) of the cooler housing (4). A thermostatically controlled valve (118) and an oil pressure responsive valve means (80) control the flow of oil through the cooler and filter assembly (2) to insure efficient and safe operation of the assembly (2). A heat exchange means (24) includes a fixed plate-like member (30) for mounting one end of each of a plurality of elongated tubes (26) and also contains oil supply and return apertures (54 and 56) which allow for simplification of the arrangement of flow passages within the assembly (2).
