Abstract:
PCT No. PCT/DE86/00453 Sec. 371 Date Jul. 17, 1987 Sec. 102(e) Date Jul. 17, 1987 PCT Filed Nov. 7, 1986 PCT Pub. No. WO87/03339 PCT Pub. Date Jun. 4, 1987.Fuel injection nozzle for internal combustion engines includes a first closing spring which acts continuously on the valve needle by means of a central pressure pin and, in addition, a second closing spring which acts continuously on the valve needle by means of a pressure piece after covering the distance of an initial stroke. The pressure piece is supported at the nozzle body by means of an intermediate bush during the initial stroke. The initial stroke is limited by means of the shoulders at the valve needle and the intermediate bush, whereas the total stroke is limited by means of the shoulders at the intermediate bush and the intermediate disk. Accordingly, the initial stroke can be adjusted very accurately to a desired magnitude merely by means of grinding the valve needle and does not change during the assembly of the injection nozzle.
