In the fuel injection pump of a reciprocating combustion engine having a suction space (7), the piston (3) starts from the end face (3 ') in contact with the transfer space (4) and in the inner circumferential region of the axial channel (13). And a cross channel 12 starting from this channel and opening to the outer circumferential region of the piston. The slider 9 surrounding the piston in the region of the cross channel is arranged axially adjustable. The slider is interlocked with the cross channel 12 to adjust the start of the feed, and the first control edge 10 perpendicular to the direction of movement of the piston, and the piston is interlocked with the cross channel 12 to adjust the end of the feed. The second control edge 11 inclined with respect to the direction of movement of the. The slider 9 or piston 3 is rotatable relative to the piston or slider, respectively, about its axis.
