Abstract
A unit fuel injector for internal combustion engines having a fuel injecting pump portion and a fuel injection valve portion which are assembled as a unit in a single injector body (6). The injector body (6) has an upper section into which a check valve (9), barrel (5), plunger (3), and so forth are inserted from the upper side of the injector body. The check valve, barrel, plunger and so forth are secured by means of a barrel holder (7) screwed into the upper section of the injector body. Also a nozzle spring (13), nozzle body (19), nozzle valve (18) and so forth are assembled and placed within from the lower side of the injector body. The nozzle spring, nozzle body, nozzle valve and so forth are fixed by a nozzle nut (20) screwed to the lower section. This arrangement permits the diameter of the unit fuel injector to be reduced to facilitate the mounting in the limited space on a cylinder head of the engine.
