Abstract
A simple, reliable bypass valve construction (50) is provided for use in conjunction with a donut oil cooler (16) having a flat, solid filter plate (36), whereby the bypass valve (52) will be self-located and self-retained to the oil cooler (16) during shipping. The bypass valve construction (50) is easily accessible and readily replaceable so as to lend itself to serviceability. The invention is incorporated in an oil cooler (16) having a housing (28) with a surface (26) adapted to be sealed against an oil filter (14). The oil cooler (16) includes a plurality of interconnected heat exchange units (21) located inside the housing (28), with an oil inlet to one of the units (21) and an oil outlet from another of the units (21). There is a centrally located opening (39) in the surface (26) of the oil cooler (16) to allow a connector (18) to pass through the oil cooler (16). A bypass valve (52) is provided and includes an inner ring (54) carrying a sheet-like resilient flapper (56) having a valve element (62) thereon sized to close a bypass outlet (64) in the housing surface (26). Tabs (80), (82), and (74) and slots (70), (72) and (76) are provided for loosely mounting the inner ring (54) to the housing surface (26) to retain the bypass valve (52) during shipment and prior to installation of the oil cooler (16).
