In this case, the nozzle needle spring 140 is supported with a first longitudinal end on the nozzle needle sleeve 115 and with a second longitudinal end on the collar 135. In this case, the nozzle needle spring 140 acts on the nozzle needle with a force directed away from the second control chamber 125 or from the upper part 10.
- the nozzle needle 110 In the closed state of the injector 15, the nozzle needle 110 abuts against a lower tip 145 of the lower part 20 of the injector 15.
