Abstract

Die Erfindung bezieht sich auf einen Druckübersetzer (1) für einen Kraftstoffinjektor. Der Druckübersetzer (1) weist einen Differenzdruckraum (4), einen Kompressionsraum (5) und einen Kolben (3) auf. Der Kolben (3) ist durch Druckänderung im Differenzdruckraum (4) betätigbar. Der Differenzdruckraum (4) ist über eine Verbindungsleitung (9, 27) mit einer Steuerleitung (8) verbunden. Der Kolben (3) zentriert Gehäuseteile (18, 19) des Druckübersetzers (1) relativ zueinander.
