Abstract
Es wird ein elektromagnetisch betätigbares Einlassventil (24) für eine Hochdruckpumpe, insbesondere eines Kraftstoffeinspritzsystems, vorgeschlagen. Das Einlassventil (24) weist ein Ventilglied (34) auf, das zwischen einer Öffnungsstellung und einer Schließstellung bewegbar ist. Es ist ein elektromagnetischer Aktor (60) vorgesehen, durch den das Ventilglied (34) bewegbar ist, wobei der elektromagnetische Aktor (60) einen zumindest mittelbar auf das Ventilglied (34) wirkenden Magnetanker (68), eine den Magnetanker (68) umgebende Magnetspule (64) und einen Magnetkern (66) aufweist, an dem der Magnetanker (68) bei Bestromung der Magnetspule (64) zumindest mittelbar zur Anlage kommt, wobei der Magnetanker (68) in einem Trägerelement (78) verschiebbar geführt ist und wobei das Trägerelement (78) und der Magnetkern (66) über ein hülsenförmiges Bauteil (90) miteinander verbunden sind. Zwischen dem Magnetanker (68) und dem diesem zugewandten Ende des Magnetkerns (66) ist ein scheibenförmiges Zwischenelement (92) angeordnet, das mit dem hülsenförmigen Bauteil (90) verbunden ist. Durch das scheibenförmige Zwischenelement (92) wird die Belastung des Magnetkerns (66) beim Anschlag des Magnetankers (68) verringert. Das Zwischenelement (92) ist aus einem nichtmagnetischen Werkstoff hergestellt, so dass durch dieses auch eine magnetische Trennung zwischen Magnetanker (68) und Magnetkern (66) bewirkt wird.An electromagnetically actuatable inlet valve (24) for a high-pressure pump, in particular a fuel injection system, is proposed. The inlet valve (24) has a valve member (34) which is movable between an open position and a closed position. An electromagnetic actuator (60) is provided, by means of which the valve member (34) is movable, wherein the electromagnetic actuator (60) has a magnet armature (68) acting at least indirectly on the valve member (34), a magnet coil surrounding the magnet armature (68) (64) and a magnetic core (66) on which the magnet armature (68) at least indirectly comes to rest when current flows through the magnetic coil (64), wherein the magnet armature (68) is guided displaceably in a carrier element (78) and wherein the carrier element (78) and the magnetic core (66) via a sleeve-shaped member (90) are interconnected. Between the magnet armature (68) and the end facing the magnetic core (66), a disc-shaped intermediate element (92) is arranged, which is connected to the sleeve-shaped member (90). By the disc-shaped intermediate element (92), the load of the magnetic core (66) is reduced when the magnet armature (68). The intermediate element (92) is made of a non-magnetic material, so that this is also a magnetic separation between the armature (68) and magnetic core (66) is effected.
Description
Die Erfindung betrifft ein elektromagnetisch betätigbares Einlassventil für eine Hochdruckpumpe, insbesondere eines Kraftstoffeinspritzsystems, gemäß dem Oberbegriff des Anspruchs 1. Ferner betrifft die Erfindung eine Hochdruckpumpe mit einem solchen Einlassventil.The invention relates to an electromagnetically operable inlet valve for a high pressure pump, in particular a fuel injection system, according to the preamble of claim 1. Furthermore, the invention relates to a high pressure pump with such an inlet valve.

Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Einlassventil mit den Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass durch das Zwischenelement eine direkte Anlage am Magnetkern vermieden ist, so dass dessen Belastung verringert ist. Durch die Verbindung des Zwischenelements mit dem hülsenförmigen Bauteil ist für dieses kein zusätzlicher Montageschritt erforderlich und dieses wird direkt bei der Montage des hülsenförmigen Bauteils zwischen dem Magnetanker und dem Magnetkern positioniert. The inlet valve according to the invention with the features of claim 1 has the advantage that a direct contact with the magnetic core is avoided by the intermediate element, so that its load is reduced. The connection of the intermediate element with the sleeve-shaped component no additional assembly step is required for this and this is positioned directly in the assembly of the sleeve-shaped member between the armature and the magnetic core.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Einlassventils angegeben. Durch die Ausbildung gemäß Anspruch 2 ist eine magnetische Trennung erreicht, so dass ein Kleben des Magnetankers am Magnetkern vermieden und die Funktion des Einlassventils verbessert ist. Durch die Ausbildung gemäß Anspruch 3 oder 4 ist eine einfache Verbindung des Zwischenelements mit dem hülsenförmigen Bauteil ermöglicht. Die Ausbildung gemäß Anspruch 6 hat den Vorteil, dass der Aufwand zur Erzeugung des hülsenförmigen Bauteils vereinfacht ist, da dieses nicht als separates Bauteil ausgeführt ist. In the dependent claims advantageous refinements and developments of the inlet valve according to the invention are given. The embodiment according to claim 2, a magnetic separation is achieved, so that sticking of the armature on the magnetic core avoided and the function of the inlet valve is improved. Due to the design according to claim 3 or 4, a simple connection of the intermediate element with the sleeve-shaped component is made possible. The embodiment according to claim 6 has the advantage that the effort for producing the sleeve-shaped component is simplified, since this is not designed as a separate component.
