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) eine Magnetspule (64), einen Magnetkern (66) und einen zumindest mittelbar auf das Ventilglied (34) wirkenden Magnetanker (68) aufweist, der in einer Aufnahme (76) eines Trägerelements (78) in Richtung seiner Längsachse (69) verschiebbar geführt ist. Der Magnetkern (66) und das Trägerelement (78) sind zumindest teilweise von der Magnetspule (64) unter Bildung eines Zwischenraums (94) umgeben. Der Zwischenraum (94) ist zumindest teilweise mit einem Kunststoffmaterial (95) ausgefüllt. Durch das Kunststoffmaterial (95) wird der Wärmeübergang von der Magnetspule (64) auf den Magnetkern (66) und das Trägerelement (78) verbessert, so dass die Temperatur der Magnetspule (64) gesenkt werden kann. 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, through which the valve member (34) is movable, wherein the electromagnetic actuator (60) comprises a magnetic coil (64), a magnetic core (66) and an armature acting at least indirectly on the valve member (34) (68) which is displaceably guided in a receptacle (76) of a carrier element (78) in the direction of its longitudinal axis (69). The magnetic core (66) and the carrier element (78) are at least partially surrounded by the magnetic coil (64) to form a gap (94). The intermediate space (94) is at least partially filled with a plastic material (95). The plastic material (95) improves the heat transfer from the magnet coil (64) to the magnet core (66) and the carrier element (78), so that the temperature of the magnet coil (64) can be lowered.
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 eine verbesserte Wärmeübertragung von der Magnetspule auf das Trägerelement und den Magnetkern ermöglicht ist, wodurch eine zu starke Erwärmung anderer Teile des Aktors und/oder des diesen umschließenden Gehäuses vermieden werden kann. Eine Kühlung ist durch den im Trägerelement vorhandenen und dieses vorzugsweise durchströmenden Kraftstoff ermöglicht. Dies ermöglicht auch die Ansteuerung der Magnetspule mit höheren Stromstärken wodurch der Einsatzbereich des Einlassventils erweitert werden kann. Außerdem ist durch das den Zwischenraum zumindest teilweise ausfüllende Kunststoffmaterial ein Eindringen von Feuchtigkeit zumindest verringert und dadurch die Funktion des Einlassventils über einen langen Zeitraum sichergestellt.The inlet valve according to the invention with the features of claim 1 has the advantage that an improved heat transfer from the solenoid to the support member and the magnetic core is made possible, whereby excessive heating of other parts of the actuator and / or enclosing this housing can be avoided. Cooling is made possible by the fuel present in the carrier element and preferably flowing through it. This also allows the control of the solenoid with higher currents whereby the range of application of the inlet valve can be extended. In addition, the penetration of moisture is at least reduced by the plastic material at least partially filling the intermediate space, thereby ensuring the function of the inlet valve over a long period of time.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Einlassventils angegeben. Die Ausbildung gemäß Anspruch 2 hat den Vorteil, dass ein Wärmeübergang von der Magnetspule weiter verbessert ist. Durch die Ausbildung gemäß Anspruch 3 ist der Wärmeübergang von der Magnetspule weiter verbessert und gemäß Anspruch 4 ist wenigstens eine Schweißverbindung des Verbindungselements gegen Korrosion geschützt. Durch die Ausbildung gemäß Anspruch 5 kann das Kunststoffmaterial auf einfache Weise in den Zwischenraum eingebracht werden.In the dependent claims advantageous refinements and developments of the inlet valve according to the invention are given. The embodiment according to claim 2 has the advantage that a heat transfer from the magnetic coil is further improved. The embodiment according to claim 3, the heat transfer from the magnetic coil is further improved and according to claim 4, at least one welded joint of the connecting element is protected against corrosion. Due to the construction according to claim 5, the plastic material can be introduced in a simple manner in the intermediate space.
