Abstract

1329535 Fuel injectors ROBERT BOSCH GmbH 2 May 1972 [3 May 1971] 20317/72 Heading F1B A fuel injector nozzle having a valve needle 4, Fig. 1 in a nozzle body releasably connected to a nozzle holder has a ball 11 guided in a radial bore in the nozzle body so that a segment of the ball, which is less than half circumference, engages a semi-circular groove in the valve needle to prevent its rotation. A screw threaded retaining plug 13 may be replaced by a bolt retained by a spring ring.
