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) miteinander verbunden sind. Das Trägerelement (78) und der Magnetkern (66) sind über ein hülsenförmiges Verbindungselement (90) miteinander verbunden, das zumindest abschnittsweise in Richtung seiner Längsachse (91) elastisch verformbar ist.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) are interconnected. The carrier element (78) and the magnetic core (66) are connected to one another via a sleeve-shaped connecting element (90), which is elastically deformable at least in sections in the direction of its longitudinal axis (91).
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 die elastische Verformbarkeit des Verbindungselements der Anschlag des Magnetankers zumindest mittelbar am Magnetkern gedämpft wird, so dass die Belastung dieser beiden Bauteile verringert ist und entsprechend deren mögliche Betriebsdauer verlängert ist. The inlet valve according to the invention with the features of claim 1 has the advantage that is damped by the elastic deformability of the connecting element, the stop of the armature at least indirectly on the magnetic core, so that the load on these two components is reduced and their possible operating time is extended.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Einlassventils angegeben. Durch die Ausbildung des Verbindungselements gemäß Anspruch 2 ist auf einfache Weise die elastische Verformbarkeit des Verbindungselements erreicht. Durch die Ausbildung gemäß Anspruch 3 ist alternativ oder in Kombination mit der Ausbildung gemäß Anspruch 2 auf einfache Weise die elastische Verformbarkeit des Verbindungselements erreicht. In the dependent claims advantageous refinements and developments of the inlet valve according to the invention are given. Due to the design of the connecting element according to
