Abstract
An oil filtering and cooling device for use with an internal combustion engine is disclosed. It is composed of few components and easily fitted on or retrofitted to an internal combustion engine. In one embodiment, a pressure valve is employed to direct oil away from a cooling function yet allow for filtering thereof. The valve is a reed valve.
Claims13
An oil cooling device for use with an internal combustion engine, comprising:
- an air coolable body member adapted to be placed between an oil filter and a wall of an internal combustion engine, the body member including a cooling section and a connecting section, the connecting section being for connection to the engine wall on one side and the oil filter on another side;
- and
- fluid feed and return passages disposed internally in the connecting and cooling sections, the fluid feed passage adapted to be connected to an oil outlet port of the engine wall, and the return passage adapted to be connected to the oil filter, the oil cooling device characterized by the absence of external feed and return lines.

- a cooling body member adapted to be placed between the oil filter and a wall of an internal combustion engine, the cooling body member including a cooling section and a connecting section, the connecting section being for connection to the engine wall on one side and the oil filter on another side;
- fluid feed and return passages disposed internally in the connecting and cooling sections, the fluid feed passage adapted to be connected to an oil outlet port of the engine wall and the return passage adapted to be connected to the oil filter;
- a bypass port through the cooling body connecting section extending to permit, under certain oil pressure conditions, direct flow from the oil outlet port to the filter;
- and
- a pressure activated valve operatively associated with the bypass port to inhibit passage of lower pressure oil through the bypass port while permitting greater flow of oil through the bypass port when high pressure oil is present at the valve, the oil cooling device characterized by the absence of external feed and return lines.

An oil cooling device for use with an internal combustion engine, comprising:
- an air coolable body member connectable between an oil filter and a wall of an internal combustion engine, the cooling body member including a cooling section and a connecting section, the connecting section being for connection to the engine wall on one side and the oil filter on another side;
- and
- fluid feed and a return passages disposed internally in the connecting and cooling sections, the fluid feed passage being connectable to an oil outlet port of the engine wall and the return passage being connectable to the oil filter, with the oil filter then being capable of being in fluid communication with an oil intake port of the engine by means of a direct line passage through the connecting section, the oil cooling device characterized by the absence of external feed and return lines.
