Abstract

Die Erfindung betrifft eine Einspritzvorrichtung, insbesondere zur Common Rail-Einspritzung in Dieselmotoren, mit einer Druckleitung und wenigstens einer Einrichtung zur Messung und/oder Regelung des Druckes in der Druckleitung, wobei die Meß-/Regeleinrichtung ein Gehäuse, das an die Druckleitung angeschlossen ist und über eine Gehäuseöffnung mit der Druckleitung kommuniziert, und ein im Gehäuse angeordnetes piezoelektrisches Element umfaßt, das mit seinem einen Ende der Gehäuseöffnung zugewandt und mit seinem gegenüberliegenden Ende am Gehäuse abgestützt ist.

Figure 00000001
The invention relates to an injection device, in particular for common rail injection in diesel engines, with a pressure line and at least one device for measuring and / or regulating the pressure in the pressure line, the measuring / regulating device being a housing which is connected to the pressure line and communicates with the pressure line via a housing opening, and comprises a piezoelectric element arranged in the housing, which has one end facing the housing opening and is supported on the housing with its opposite end.
