Abstract

Bei einem Kraftstoffinjektor (1) für Brennkraftmaschinen mit einem an eine Hochdruckseite (5) angeschlossenen Steuerraum (2), über dessen Druck die Bewegung einer Düsennadel (3) gesteuert wird, und mit einem Steuerventil (6), das die Verbindung des Steuerraums (2) zu einer Niederdruckseite (7) entweder sperrt oder öffnet, weist das Steuerventil (6) erfindungsgemäß eine zwischen zwei Ventilstellungen verschiebbar geführte kraftausgeglichene Steuerhülse (10) auf, die die Verbindung eines vom Steuerraum (2) kommenden und in einen Druckraum (15) mündenden Verbindungskanals (14) zur Niederdruckseite (7) in ihrer geschlossenen Ventilstellung sperrt und in ihrer in Richtung Düsennadel (3) verschobenen geöffneten Ventilstellung freigibt, wobei die Steuerhülse (10) in ihrer geschlossenen Ventilstellung an einem Ventilsitz (17) einer Ventilplatte (11) anliegt und wobei der Druckraum (15) durch die Steuerhülse (10), die Ventilplatte (11) und ein weiteres Teil (9) begrenzt ist..
