Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
121 words
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.
Claim 2
Dependent Claim
121 words
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.
Claim 3
Dependent Claim
14 words
The device of claim 1, wherein the body member is a single piece body.
Claim 4
Dependent Claim
35 words
The device of claim 2, wherein the cooling section has externally extending fin members to permit the movement of cooling air thereover, and at least one of said passages is serpentine in the cooling section.
Claim 5
Dependent Claim
26 words
The device of claim 1, wherein the body member has a paddle shaped configuration, with the connecting section being in the shape of a paddle handle.
Claim 6
Dependent Claim
36 words
The device of claim 1, wherein the device also comprises the oil filter and the oil filter is connected to an oil intake port of the engine by a nipple member extending through the connecting section.
Claim 7
Dependent Claim
193 words
An oil filtering and cooling device for use with an internal combustion engine, comprising: an oil filter; 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.
Claim 8
Dependent Claim
193 words
An oil filtering and cooling device for use with an internal combustion engine, comprising: an oil filter; 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.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
48 words
The device of claim 6, wherein the oil filter is adapted to be connected to an oil intake port of the engine by a passage extending through a central region of the connecting section, and a return passage and bypass port in the connecting section are offset therefrom.
Claim 11
Dependent Claim
20 words
The device of claim 6, wherein the cooling section and the connecting section are formed as a one piece body.
Claim 12
Dependent Claim
27 words
The device of claim 9, wherein the cooling section and the connecting sections are formed from cast aluminum and the cooling section has externally extending cooling fins.
Claim 13
Dependent Claim
147 words
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.
Claim 14
Dependent Claim
