Abstract
A filter device for filtering fluids such as fuels, including diesel fuel, has a filter housing (), within which a filter element () can be fastened and exchanged. The filter element has a filter medium that surrounds an inner filter cavity (). A fluid inlet leads to the unfiltered side () of the filter element (). A fluid outlet outflows filtered fluid from the filtered side (). An equalizing tube () extends in the filter housing () up to a maximum filling level height for the filtration operation. The equalizing tube is connected to a tank return connection at a lower end of the equalizing tube and is open at an upper end () of the equalizing tube. The tube () has, at distances from the upper and lower ends of the tube, an inner control part () with a passage opening () forming a throttle point.
