FILTER DEVICE

摘要

A filter device for filtering fluids, such as fuels, including diesel fuel, comprising a filter housing (1), inside which a filter element (17) can be fastened in an exchangeable manner, which filter element has a filter medium that surrounds an inner filter cavity (25), a fluid inlet (21) leading to the unfiltered side (27) of the filter element (17), a fluid outlet (9) for the outflow of filtered fluid from the filtered side (25), and a tank return connection (13), is characterized in that an equalizing tube (49) is provided extending in the filter housing (1) up to a maximum filling level height provided for the filtration operation, which equalizing tube is connected at its bottom end to the tank return connection (13) and is open at its top end (51), and in that the tube (49) has, at a point located at a distance from the top and bottom end of the tube, an inner control part (60), in which a through-hole (61) is located, which forms a throttle point.
