Abstract

Die Erfindung betrifft ein Magnetventil (2) zur Steuerung eines Einspritzventils (1) einer Brennkraftmaschien, umfassend einen Elektromagneten (34), einen beweglichen Anker (29), ein mit dem Anker (29) bewegtes und mit einem Ventilsitz (24) zusammenwirkendes Steuerventilglied (25, 26) zum Öffnen und Schliessen eines Kraftstoffablaufkanals (17) eines Steuerdruckraums (14) des Einspritzventils und ein den Anker (29) führendes Gleitstück (40), welches zusammen mit dem Anker (29) und dem Steuerventilglied (25, 26) in einem Ankerraum (51, 52) angeordnet ist. Zur Verringerung des Ankerprellens wird vorgeschlagen, dass das Gleitstück (40) den Ankerraum in einen mit einem Kraftstoffniederdruckanschluss (10) verbundenen Entlastungsraum (52) und einen hydraulischen Dämpfungsraum (51) unterteilt, in den der Kraftstoffablaufkanal (17) einmündet, welcher Dämpfungsraum über wenigstens einen mit einer Drossel (43, 48) versehenen Verbindungskanal (44, 47) zum Entlastungsraum (52) hin entlastbar ist, wobei die Geschwindigkeit des Steuerventilgliedes (25, 26) beim Schliessen des Magnetventils (2) vor dem Anschlag am Ventilsitz (24) durch ein in dem Dämpfungsraum (51) auf das Steuerventilglied (25, 26) einwirkendes Kraftstoff-Druckpolster verringert wird.
