Abstract (en)
[origin: EP1705365A2] The injector has a prestroke sleeve (13) that travels a prestroke distance during the opening movement of an injection valve unit (9) until it reaches a changeover point of the pressure boosting. A prestressing spring (21) is provided in the form of a tube spring and is contained between a collar (22) and a lower end of the sleeve. The spring operates to continuously build up the force required to switch the pressure boosting from one opening pressure to another opening pressure during the passage through the prestroke distance.
