Abstract
Abstract An oil cooler unit is described for use in combination with an internal combustion engine to cool the oil in the engine. The oil cooler can be threaded onto the oil filter mounting plate, and an oil filter can be threaded onto the opposite end of the oil cooler. As heated oil proceeds through the cooler, heat is dissipated through fins secured to the body of the oil cooler unit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
An oil cooler comprising: (a) a body member having a central axis, first and second ends and a plurality of longitudinal conduits extending through said body member parallel to said central axis; wherein each said end of said body member includes a threaded attachment aperture; and wherein each said end of said body member includes a cavity which communicates with said conduits; (b) a plurality of spaced-apart fin members secured to said body member and extending outwardly from said body member for dissipating heat from heated fluid passing through said conduits.
Claim 2
Dependent Claim
91 words
An oil cooler comprising: (a) a body member having a central axis, first and second ends and a plurality of longitudinal conduits extending through said body member parallel to said central axis; wherein each said end of said body member includes a threaded attachment aperture; and wherein each said end of said body member includes a cavity which communicates with said conduits; (b) a plurality of spaced-apart fin members secured to said body member and extending outwardly from said body member for dissipating heat from heated fluid passing through said conduits.
Claim 3
Dependent Claim
22 words
An oil cooler in accordance with claim 1, wherein said fin members are perpendicular to the longitudinal axis of said body member.
Claim 4
Dependent Claim
23 words
An oil cooler in accordance with claim 1, wherein said body member and said fin members are integral and are composed of metal.
Claim 5
Dependent Claim
43 words
A combination comprising: (a) an oil cooler in accordance with claim 1; (b) an angle adaptor detachably mounted to said first end of said oil cooler; wherein said adaptor includes first and second faces and conduits extending through said adaptor between said faces.
Claim 6
Independent Claim
151 words
A method for cooling oil from an internal combustion engine comprising the steps of: (a) providing an oil cooler comprising: (1) a body member having a central axis, first and second ends and a plurality of longitudinal conduits extending through said body member parallel to said central axis; wherein each said end of said body member includes a threaded attachment aperture; and wherein each said end of said body member includes a cavity which communicates with said conduits; (2) a plurality of spaced-apart fin members secured to said body member and extending outwardly from said body member for dissipating heat from heated fluid passing through said conduits; (b) attaching one of said ends of said oil cooler to said engine in a manner such that oil from said engine can flow into said conduits in said oil cooler; (c) attaching an oil filter to the opposite end of said oil cooler.
