    Abstract: A filter element for a filter system for filtering a fluid has a filter bellows arranged about a longitudinal axis and enclosing an interior of the filter element. An end disk that is provided with an opening to the interior of the filter element is arranged at the filter bellows. The end disk has a bead that is arranged at the opening to the interior and partially surrounds the opening to the interior. The bead projects outwardly in a direction of the longitudinal axis. The filter system has a housing with a cover and a housing part closable by the cover. The filter element can be exchangeably arranged in the housing. The bead, in a mounted state of the filter element in the housing, engages a complementary receptacle arranged at an inner side of the cover.

  • Publication number: 20200346152
    Abstract: A filter housing for a filter device is provided with an inlet housing arranged upstream of a filter element. The inlet housing has an inflow opening for introducing a fluid to be purified into the filter housing. The inlet housing has an overflow opening at an outlet of the inlet housing, wherein the overflow opening conveys the fluid to be purified to the filter element. The inlet housing has an inlet channel disposed between the inflow opening and the overflow opening. The inlet channel has an intermediately positioned channel section located between the inflow opening and the overflow opening, wherein a cross-sectional shape of the intermediately positioned channel section differs from a cross-sectional shape of the inflow opening and from a cross-sectional shape of the overflow opening.
