Abstract
Description
Stand der TechnikState of technology
Die Erfindung geht aus von einem Injektor nach der Gattung des Patentanspruchs 1.The invention is based on one Injector according to the preamble of claim 1.
Bei einem solchen zum Beispiel aus
Durch den Dämpfungsraum des erfindungsgemäßen Injektors werden Druckschwingungen hydraulisch gedämpft. Die auf Druckstange und Düsennadel nicht übertragene Schwingung verhindert im geschlossenen Zustand der Düsennadel Verschleiß.Through the damping space of the injector according to the invention pressure vibrations are damped hydraulically. The on push rod and nozzle needle not transferred Vibration prevents the nozzle needle from being closed Wear.
Weitere Vorteile und vorteilhafte Ausgestaltungen des Gegenstands der Erfindung sind der Beschreibung, der Zeichnung und den Ansprüchen entnehmbar.Other advantages and beneficial Embodiments of the object of the invention are the description, the drawing and the claims removable.
