  • Patent number: 4426965
    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).

  • Patent number: 4191148
    Abstract: The disclosure illustrates a water to air aftercooler assembly in which an elongated coolant tube bundle is supported by plates spaced between heat exchange fins to form an aftercooler core. The support plates are secured to opposed walls forming a part of the aftercooler housing. This arrangement permits a simplified and economical aftercooler core. In addition it provides an improved support for the aftercooler core and structurally reinforces the aftercooler housing.
