FILTER DEVICE

A filter device may include a filter housing with a filter housing pot and a cover screwable onto the filter housing pot, and an annular filter element arranged in the filter housing and having an axially protruding pin for closing a run-off channel. The annular filter element may be connected to the cover via a first thread, which may have a dome protruding centrally and axially from an upper end disc of the annular filter element. The first thread may be designed running counter to a second thread arranged between the filter housing pot and the cover.
