Two-stage oil bypass filter device

A new and improved two-stage oil bypass filter device is provided to enable effective and efficient removal of both solid particulate and volatile oil contaminants while also allowing the addition and mixing of certain oil additives as required by specific internal combustion engine or industrial applications. The novel two-stage oil bypass filter device includes a cone-shaped vaporization plate having a heating element located below the surfaces to be heated to provide for more effective and efficient heating of those surfaces critical to removing volatile contaminants, a horseshoe-shaped oil staging channel to provide preheating of the oil, a post-filter flow reducer to greatly reduce the possibility of clogging, a readily replaceable spin-on filter cartridge having a centrally located oil feed tube and an oil diffuser plate which directs the oil to be filtered to all parts of the filter media within the cartridge, an additives package configuration within the filter cartridge for continuous addition and mixing of oil additive substances to the oil being filtered, and a high grade, high impact thermoplastic cap housing to prevent external heating and considerably reduce the potential for burn accidents.
