Publication number: 20210268411Abstract: The disclosure pertains to a filter assembly comprising a base, a cover, and a cylindrical filter element, the base being adapted to receive the cover with the filter element inserted therein. The base has an outlet orifice with a first sealing zone, and a drainage orifice with a second sealing zone. The filter element comprises an outlet tube with a first sealing element, and a drainage plug with a second sealing element, said outlet tube and said drainage plug being positioned to sealingly engage with said first sealing zone and said second sealing zone, respectively, when the base receives the cover. An axial distance (A) between the first sealing element and the second sealing element is different from an axial distance (B) between an end of the first sealing zone and an end of the second sealing zone facing the filter element. The present disclosure also pertains to a filter element for use in such a filter assembly.Type: ApplicationFiled: May 20, 2021Publication date: September 2, 2021Inventors: Gunter VAN DE POEL, Lukasz HANDZLIK, Joost ROELS, Erwin VERBELEN, Luca GHISU
