<p>A by-pass refining device (10) for an internal combustion engine has separate vaporization and filtering portions. The vaporization element (12) is formed of stamped metal members assembled together to define a vaporization chamber (16) and a pressure chamber (38). The vaporization element (12) has a filtered oil inlet (20). The filtering element is a detachable filter cartridge (48) containing a porous filtering material (54) and having a filtered oil outlet (95). The filtered oil inlet (20) of the vaporization canister (14) and the filtered oil outlet (95) of the filter cartridge (48) are both mating, threaded fittings which allow the vaporization element (12) and filter cartridge (48) to be screwed together. The vaporization element (12) can be mounted in an engine compartment of the vehicle and the disposable cartridge (48) can be threadably engaged therewith. Alternatively, the disposable cartridge (48) can be remotely located and coupled to the vaporization element (12) by a hose (47) having appropriate threaded fittings. To enhance the filtering capability a plurality of disposable cartridges (48) can be threadably engaged in series and coupled to a single vaporization element (12). </p> |
