The fuel injection device is designed as a compact module. The fuel is to be supplied through a bore of the housing of the fuel injection internal combustion engine. For accommodating the fuel filter in a protected manner without detracting from the mechanical strength of the housing, the fuel supply conduit opens into a space located at the side of the flange directed toward the nozzle, noting that the flange has at least one axial opening connecting the space located at the side of the flange directed toward the nozzle with the suction space of the pump piston. The fuel filter is arranged between the space located at the side of the flange directed toward the nozzle and the suction space.

In a fuel injection device for an internal combustion engine: an injection pump unit having a longitudinal axis and including an internal pump suction space, an internal longitudinally movable pump piston, and at one end a fuel injection nozzle through which fuel may be injected from said pump suction space into an engine cylinder, said pump unit having an annular flange intermediate its ends which fits into a recess in the engine, said flange in conjunction with the wall of said recess forming a fuel-containing space which is located on the nozzle-side of said flange and which is located so as to receive fuel from a fuel supply bore in the engine housing communicating with the recess in the engine housing; at least one axial opening in said flange placing said fuel space in communication with said pump suction space; and a fuel filter associated with said opening so that fuel flows in an axial direction from said fuel space through said fuel filter to said pump suction space.
