A fuel injection pump for internal combustion engines, having a reciprocating pump piston and an annular slide displaceable on the pump piston and having a control bore which cooperates with a control recess on a pump piston that communicates with the pump work chamber via a conduit. Because of a crooked position of the control bore with respect to the piston axis, an ellipse-like opening cross section is created, which in cooperation with the oblique control edge opens a fast, large opening cross section, by way of which in cooperation with an equal pressure valve disposed in the injection line, the fuel can flow out quickly, and a reliable, fast closure of the injection valve is assured. A pressure holding valve is also provided which opens toward the work chamber.
