Abstract
A filter device usable with diesel fuels, includes a filter element () exchangeably accommodated in a filter housing. A fluid pump device () having two pump chambers () is part of the filter device. The pump chambers, by a pump piston () guided in the chambers in a longitudinally movable manner, are separated from each other fluid-tight at least in one of the two directions of movement of the pump piston. Each pump chamber () is assigned a valve () opening or closing oppositely to the other valve () when the pump device () is actuated.
