Abstract
A fuel injection pump is proposed for internal combustion engines having a pump piston having a blind bore and two control bores and in which the fuel quantity to be supplied is controlled by means of a control slide having oblique control edges. At least two control edges are provided in a window-like recess of the control slide, of which the lower edge in each case and possibly the upper one as well extend obliquely; the upper control edge provided in the recess determines the supply onset, in cooperation with the first control bore, and the lower control edge of the recess determines the end of supply, in cooperation with the second control bore.
