Abstract

A filter arrangement may include a filter housing and a ring filter element arranged in the filter housing. The ring filter element may include an upper end plate, a lower end plate, and a filter material arranged therebetween. An axially projecting pin may be disposed on the lower end plate and may engage into a channel on a filter housing side. The filter arrangement may also include a tubular dome which may engage into an interior of the ring filter element. The tubular dome may have a guide contour. The guide contour may cooperate with a guide element arranged on the ring filter element and may have an axial groove. The guide contour may be configured as at least one of a circular ramp and a chamfered cannula. On the upper end plate, an axial stop may project into the interior of the ring filter element.
