Abstract
A filter device may include a filter housing cup, a filter head, and a ring filter element arranged in the filter housing cup. The ring filter element may include an upper end plate on which at least two radially outward projecting bayonet wings are arranged which interact with a plurality of recesses disposed in the filter housing cup. The plurality of recesses may respectively define an undercut contour and a first end position of an associated bayonet wing guided therein. At least two driving elements may be arranged on the upper end plate. At least two ramps and two stops may be arranged on the filter head such that, when fitting the filter device, the at least two driving elements slide on the at least two ramps to the two stops and press the at least two bayonet wings into the undercut contour of an associated recess.
