Abstract: The invention relates to a filter device, in particular provided for use with diesel fuels, comprising a filter element (19) that can be exchangeably accommodated in a filter housing, which filter device is characterized in that a fluid pump device (46) having two pump chambers (45, 49) is present as part of the filter device, which pump chambers, by means of a pump piston (51) guided in said chambers in a longitudinally movable manner, are separated from each other in a fluid-tight manner at least in one of the two directions of movement of the pump piston, and that each pump chamber (45, 49) is assigned a valve (39, 63), which opens or closes oppositely to the other valve (39, 63) when the pump device (46) is actuated.
