Oil filler cap with swivel hose fittings

Abstract

An improved oil filler cap is presented, designed to support the reintroduction of super clean oil from a bypass oil filter attached to a gasoline or diesel engine. The improved filler cap is designed to be shorter in height than state-of-the-art bypass filler caps, removing an unneeded structure supporting the nozzle receiving the super clean oil. This invention is directed towards vehicles with low hood clearance in their engine compartments.

1 . an improved engine oil filler cap, the engine oil filler cap comprised of a filler cap, an O-ring, a swivel plug, a snap ring, a swivel nozzle, and an oil filler cap gasket,
 the filler cap possessing a cylindrical hole through its center, the cylindrical hole lined with a cylindrical hole gasket on its circumference,   the swivel plug possessing a cylindrical receptacle threaded with screw threads, the swivel nozzle possessing an input and a cylindrical lower part covered with screw threads.   
   
   
       2 . A method of assembling an engine oil filler cap as in  claim 1 , the method comprised of the steps of
 inserting an O-ring into the circumference of the cylindrical hole in the filler cap,   fitting the swivel plug into the cylindrical hole of the filler cap until it seats,   inserting the snap ring above the swivel plug under the rim of the cylindrical hole,   screwing the swivel nozzle into the cylindrical receptacle of the swivel plug until it seats,   inserting the oil filler cap gasket into the underside of the filler cap,   screwing the entire assembly onto an oil filler opening.   
   
   
       3 . A method of using the engine oil filler cap as in  claim 1 , comprised of the steps of
 assembling the oil filler cap as in  claim 2 ,   attaching the output from a bypass oil filter, an oil cooler, or both to the input of the swivel nozzle.
