ABSTRACT:
A fuel injection pump for internal combustion engines having a plurality of pump elements 2, 3 disposed in a line, the injection quantity control of which is effected via a control slide 9 that is axially displaceable on the pump piston 9 and by controlling a relief conduit 22-25 of the pump work chamber 18, the control slides 9 being surrounded by partial suction chambers 8 that discharge into a main suction chamber 10 receiving a torque shaft 12 for axially actuating the control slides 9. These partial suction chambers 8 each have a separate partial inflow conduit 39 of defined length and cross section, which communicates with an inflow conduit 33, so that the same volumetric flow is metered to each partial suction chamber in the manner of quantity division, while the main suction chamber 10 is retained and the torque shaft 12 is disposed in it.
