Fuel injection pump for internal combustion engines

摘要

A fuel injection pump is proposed for internal combustion engines having a control slide displaceable on the pump piston. The control slide cooperates with an oblique groove on a pump piston. The oblique groove is arranged to communicate via a conduit with a pump work chamber. The pump piston is rotatable and has a longitudinal groove of predetermined length on its jacket surface, which groove is adapted to communicate with the oblique groove and with its end remote from the pump work chamber determines the supply onset of the pump by plunging into the control slide.
