Abstract
Fuel injection pump for internal combustion engines comprising at least one pump element consisting of a cylinder liner (2) and a pump plunger (3), and comprising a control slide (9) on the pump plunger (3) which is rotatable for the fuel control. The control slide (9) is axially displaceable for the purpose of changing the start of injection, wherein the axial displacement is effected by means of a rotating shaft (12) which is supported in the pump housing (1), at least one adjusting bolt (14) being fastenable at the rotating shaft (12) in its installation position by means of a fastening part (clamping nut 15) after adjustment. An eccentric stud (37) of the eccentric bolt (14) is constructed so as to be cylindrical, and a slide shoe (44), which has a rectangular shape with curved contact surfaces (51), is insertable on the stud (37) by means of a central borehole (40) in order, accordingly, to ensure a line contact between the slide shoe (44) and the groove (13), and is secured against falling out by means of a pin (45).
