FIELD: mechanical engineering; fuel systems of internal combustion engines. SUBSTANCE: proposed device has housing of fuel injection pump, plunger barrel with tooth on its cylindrical surface, adjusting screw with ring groove and conical surfaces forming self-braking pair together with threaded sections of housing tangential hole. Conical surfaces of screw with recesses on plunger barrel form stops limiting travel of adjusting screw. EFFECT: provision of rigid fixing of plunger barrel, improved conditions of operating and assembling. 2 cl, 3 dwg
