Title (EN) TWO-STAGE OIL BYPASS FILTER DEVICE
(FR) FILTRE D'HUILE EN DERIVATION A DEUX ETAGES
Abstract:
(EN) A new and improved two-stage oil bypass filter device (10) 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 (10) includes a cone-shaped vaporization plate (40) having a heating element located below the surfaces (64) 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 (39) to provide preheating of the oil, a post-filter flow reducer (59) to greatly reduce the possibility of clogging, a readily replaceable spin-on filter cartridge (30) having a centrally located oil feed tube (77) and an oil diffuser (80) plate which directs the oil to be filtered to all parts of the filter media within the cartridge (30), and additives package configuration (60) within the filter cartridge for continuous addition and mixing of oil additive substances (86) to the oil being filtered, and a high grade, high impact thermoplastic cap housing (11) to prevent external heating and considerably reduce the potential for burn accidents.
(FR) L'invention concerne un nouveau filtre (10) d'huile en dérivation à deux étages efficace pour l'élimination des contaminants d'huile sous forme tant particulaire solide que volatile, qui permet également l'adjonction et le mélange de certains additifs d'huile selon les besoins spécifiques de moteurs à combustion interne ou d'applications industrielles. Ce nouveau dispositif (10) comporte une plaque de vaporisation conique (40) à élément chauffant qui se trouve sous les surfaces (64) à chauffer; une fois activé, cet élément optimise la chauffe des surfaces critiques pour l'élimination des contaminants volatils. Ledit dispositif comporte en outre un canal à huile de transfert d'étage en forme de fer à cheval (39) pour le préchauffage de l'huile, un réducteur (59) de flux post-filtre qui réduit considérablement le risque d'encrassement, une cartouche filtrante facilement amovible (30) ayant un tube central (77) d'alimentation d'huile et une plaque (80) de diffusion d'huile qui achemine l'huile à filtrer vers toutes les parties du système filtrant dans la cartouche (30), une configuration de récipient pour additif (60) dans la cartouche filtrante pour ajouter et mélanger en continu les additifs (86) d'huile dans l'huile filtrée, ainsi qu'un capuchon (11) thermoplastique de haute qualité et de résistance élevée qui empêche la chauffe externe et réduit considérablement le risque d'accidents par brûlure.
