Abstract

1366577 Fuel injection nozzles ROBERT BOSCH GmbH 19 April 1972 [23 April 1971] 18062/72 Heading F1B In a fuel injection nozzle, an intermediate plate 4 disposed between a nozzle body 1 and a nozzle holder 3 is located relative thereto by dowels 6 and has at least one fuel bore 7 (or 7b), the dowels and the fuel bores each being arranged symmetrically with respect to a plane Z in which the nozzle axis Y lies. The dowels and the fuel bores each lie in parallel planes X1 and X2 which are spaced from the nozzle axis Y. The intermediate plate 4 limits the stroke of valve needle 5. If the plate 4 has a recess in one side or recesses of different depths in the two sides, the stroke of the needle can be adjusted by turning over the plate.
