Title (EN) IMPROVED SEALING FOR VERTICALLY MOUNTED AIR FILTER ELEMENT
(FR) ÉTANCHÉITÉ AMÉLIORÉE POUR ÉLÉMENT DE FILTRE À AIR MONTÉ VERTICALEMENT
Abstract:
(EN) This invention comprises an Air filter element frame for the internal combustion engine of seal comprising a compressible seal or compressible gasket; illustrated by a polyurethane foam seal/gasket; and a process of making the illustrative seal/gasket wherein two parts of a mould provide a channel around the four margins of the air filter elements that have Guide Slots and molten polyurethane mixture is filled up, entrained with air bubbles and the compressible seal is formed around the margins. The Air filter element frame made of thermoplastic material combined with additives comprises an air filter element frame holding feature, filter paper media, a Guide Slot provided on all the four margins holding the polyurethane foam seal/gasket that facilitates assembly by press fitting. The filter paper media used are insert molded into the air filter element frame.
(FR) La présente invention concerne un cadre d'élément de filtre à air pour moteur à combustion interne à joint comprenant un joint compressible ou une garniture d'étanchéité compressible, par exemple un joint/une garniture d'étanchéité en mousse de polyuréthane ; et un procédé de fabrication du joint/de la garniture d'étanchéité donné(e) à titre d'exemple, deux parties d'un moule formant un canal autour des quatre bords des éléments de filtre à air qui comportent des fentes de guidage et un mélange de polyuréthane fondu étant remplies et entraînées par des bulles d'air, et le joint compressible étant formé autour des bords. Le cadre d'élément de filtre à air en matériau thermoplastique combiné à des additifs comprend une structure de maintien de cadre d'élément de filtre à air, des supports de papier filtre, et une fente de guidage ménagée sur l'ensemble des quatre bords maintenant le joint/la garniture d'étanchéité en mousse de polyuréthane qui facilite l'assemblage par emmanchement. Les supports de papier filtre utilisés sont moulés par insertion dans le cadre d'élément de filtre à air.
