Title (EN) AIR CLEANER WITH REPLACEABLE FILTER ELEMENT
(FR) EPURATEUR D"AIR AVEC ELEMENT FILTRANT INTERCHANGEABLE
Abstract: front page image
(EN)An improved filter element assembly (30) for use in an air cleaner (2) on an internal combustion engine comprises a perforated inner liner (32). A replaceable filter element (54) comprising a pleated filter medium (56) is releasably coupled to the inner liner (32). A safety sleeve assembly (44) is interposed between the filter medium (56) and the inner liner (32). An outer liner (68) surrounds the filter medium (56) and exerts a radially inward force thereon to bias the pleats into engagement with the inner liner (32) The filter element assembly (30) can be reconditioned when the filter medium (56) becomes used with a replacement kit (90) which includes a new filter element (54), safety sleeve assembly (44), and outer liner (68). The used filter element assembly (30) is disassembled and the worn components thereof replaced with the new components of the kit (90). The filter medium (56) is expandable from a collapsed cylindrical form, in which the filter element (54) is shipped, to an expanded conical form for use during filtering operations.
(FR)Un assemblage d"element filtrant ameliore (30) utilise dans un epurateur d"air (2) d"un moteur a combustion interne comprend une garniture interne perforee (32). Un element filtrant interchangeable (54) consistant en un filtre en accordeon (56) est assujetti de maniere amovible a la garniture interne (32). Un assemblage a manchon de securite (44) est interpose entre le moyen filtrant (56) et la garniture interne (32). Une garniture externe (68) entoure le moyen filtrant (56) et exerce une force radiale vers l"interieur sur le filtre (56) pour pousser les plis a s"engager avec la garniture interne (32). L"assemblage d"element filtrant (30) peut etre reconditionne lorsque le filtre (56) est use avec un jeu de remplacement (90) qui comprend un element filtrant (54), un assemblage a manchon de securite (44) et une garniture externe (68) neufs. L"assemblage d"element filtrant (30) utilise est demonte et ses composants uses sont remplaces parles composants neufs du jeu (30). Le moyen filtrant (56) est extensible a partir d"une forme cylindrique rabattue, dans laquelle l"element filtrant (54) est monte, en une forme conique deployee utilisee pendant la filtration.
