Abstract
A fuel injection pump having a pump piston in a bore of a pump cylinder, wherein the pump piston is rotatable for fuel control, and having a niche disposed in the pump cylinder for receiving a control slide, wherein the niche can be made by non-cutting shaping. The niche has a flat niche bottom, which changes into two oblique niche walls, which extend in two straight parallel niche walls facing one another, these parallel niche walls in turn, change into oblique faces and terminate in slideways, in which the control slide is guided against twisting by slide runners that simultaneously act as impact aprons. The niche is embodied by non-cutting shaping in such a way that its wall thickness relative to the cylindrical outer shape of the pump cylinder is embodied as virtually constant.
