Abstract:
Apparatus of unitary construction for attachment to a motorcycle for filtering and cooling engine oil, said apparatus comprising, in combination:an oil filter support member of rigid construction having a primary oil inlet for receiving engine oil from the motorcycle, a primary oil outlet for returning engine oil to the motorcycle, a secondary oil inlet and a secondary oil outlet; connector means for connecting said oil filter support to the motorcycle; an oil cooler attached to said oil filter support and supported thereby, said air cooler defining an air cooled chamber and having a generally U-shaped configuration; an oil filter having a housing attached to said oil filter support, said housing and said oil filter support defining a space in fluid flow communication with said primary oil inlet for receiving the engine oil from said primary oil inlet via said oil filter and said space further in fluid flow communication with said secondary oil inlet for delivering the engine oil to said secondary oil inlet after passage of the engine oil through said space, said secondary oil inlet for delivering the engine oil to said secondary oil outlet and to said air cooled chamber, and said primary oil outlet for receiving the engine oil from said air cooled chamber and for returning the engine oil to the motorcycle; a threaded attachment nipple threadedly attaching said oil filter to said oil filter support to support said oil filter, said threaded attachment nipple defining a fluid flow passageway between said oil filter and said secondary outlet; and engine oil lines attached to said oil filter support at said primary oil inlet and said primary oil outlet, said air cooler partially surrounding said housing and disposed in front of and to the sides of said housing along the length of the housing to protect the housing against impact and including heat dissipating, outwardly directed, radially spaced fins disposed in front of and to the sides of said housing, said air cooled chamber comprising a serpentine engine oil flow path located between said secondary oil outlet and said primary oil outlet and extending substantially the full length of said air cooler, said fins extending away from said serpentine engine oil flow path.
