The vane-cell pump of a fuel injection pump for internal combustion engines has one or more adjustable throttle restrictions disposed on the intake side and/or on the compression side. By adjusting the particular throttle restriction, the slope of the characteristic curve of the course of the supply pump pressure can be influenced. In this way, it is possible to effect an increase in the slope over the entire rpm range, an increase only in the upper rpm range, or a lesser increase in slope only in the upper rpm range. The invention contemplates several embodiments which essentially cover location of the throttle restriction in the fuel injection pump.
