Tank venting filter

摘要

A tank venting filter is provided with a housing extending in a direction of a longitudinal filter axis and provided with a bottom side and a topside opposite the bottom side. A filter element is arranged in the housing. The housing has an air inlet at the bottom side and an air outlet at the topside. The air inlet is provided in the housing transverse to the longitudinal filter axis. The housing has a housing bottom at the bottom side, wherein the housing bottom closes off a filter interior of the housing in a downward direction and is positioned at a spacing from the filter element. The housing bottom has an inner side facing the filter interior. The inner side ends in the air inlet and is positioned at least sectionwise at an obtuse angle relative to the longitudinal filter axis.
