A high-pressure pump for supplying internal combustion engines with fuel includes a housing, on which a timing unit for displacing the point of injection is accommodated. The timing unit includes an injection timing piston having inlet bores, and a regulating slide, whose face facing a cold-start accelerator piston has a prestress force applied to it, is movably accommodated in the injection timing piston. A spring element, which is applied directly to the injection timing piston, as well as a spring assembly, which is independent of the spring element and accommodated on a carrier and act on the regulating slide, are positioned between the cold-start accelerator piston and the opposing face of the injection timing piston.

Mechanical distributor injection pump having cold-start acceleration

Delivery valve

A fuel injection pump including a housing having an adjustable coupling device on the outside of the housing by which the speed governor can be adjusted from outside the housing of the fuel injection pump. By use of the adjustable coupling device on the outside of the housing, it is possible to eliminate production-oriented parts tolerances by means of adjustments of the speed governor, without tampering with its internal conditions.
