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.The invention relates to a pressure booster (1) for a fuel injector. The pressure booster (1) has a differential pressure chamber (4), a compression chamber (5) and a piston (3). The piston (3) can be actuated by changing the pressure in the differential pressure chamber (4). The differential pressure chamber (4) is connected via a connecting line (9, 27) to a control line (8). The piston (3) centers housing parts (18, 19) of the pressure booster (1) relative to each other.
