Stand der TechnikState of the art
Die Erfindung geht aus von einem Kraftstoffeinspritzventil nach der Gattung des Patentanspruchs 1.The The invention is based on a fuel injection valve after Genus of claim 1.
Ein
derartiges Kraftstoffeinspritzventil ist beispielsweise durch die
Bei diesem bekannten Kraftstoffeinspritzventil werden eine oder mehrere Einspritzöffnungen durch die Längsbewegung einer Düsennadel auf- und zugesteuert. Durch den Druck in einem Steuerraum wird eine Schließkraft mittelbar über einen Ventilkolben auf die Düsennadel ausgeübt, so dass diese, wenn im Steuerraum ein entsprechend hoher Kraftstoffdruck vorhanden ist, in ihrer Schließstellung gehalten wird. Soll eine Einspritzung erfolgen, so wird der Steuerraum mit einem Leckölraum mittels eines als Magnetventil ausgeführten Steuerventils verbunden. Das Steuerventil weist als Steuerventilelement eine Ventilhülse auf, die einen Ringraum nach außen begrenzt, welcher mit dem Steuerraum über eine Ablaufdrossel verbunden ist. Die Ventilhülse wird kräftefrei bzw. druckausgeglichen betrieben, d. h., auf die Ventilhülse wird keine durch den Kraftstoffdruck im Ringraum resultierende Kraft in deren Bewegungsrichtung ausgeübt. Durch eine Schließfeder wird die Ventilhülse gegen einen Ventilsitz gepresst und verschließt dadurch den Ringraum nach außen. Soll eine Einspritzung erfolgen, so wird die Ventilhülse über den Elektromagneten vom Ventilsitz abgehoben, was durch die fehlende hydraulische Kraftkomponente unter Überwindung der relativ kleinen Schließkraft der Schließfeder sehr schnell geschehen kann. Dadurch wird der Steuerraum mit dem Leckölraum verbunden und dadurch druckentlastet.at This known fuel injection valve will be one or more Injection openings by the longitudinal movement of a Nozzle needle opened and closed. By the pressure in one Control room will indirectly overflow a closing force a valve piston is exerted on the nozzle needle, so this, if in the control room a correspondingly high fuel pressure is present, is held in its closed position. If an injection takes place, then the control room with a Leakage oil space by means of a designed as a solenoid valve Connected control valve. The control valve has a control valve element as a Valve sleeve, which limits an annular space to the outside, which is connected to the control room via an outlet throttle is. The valve sleeve is force-free or pressure-balanced operated, d. h., on the valve sleeve is not through the fuel pressure in the annulus resulting force in the direction of movement exercised. By a closing spring, the valve sleeve pressed against a valve seat and thereby closes the annulus to the outside. If an injection should take place, so the valve sleeve is over the electromagnet lifted off the valve seat, due to the lack of hydraulic force component overcoming the relatively small closing force the closing spring can happen very quickly. This will the control room connected to the leakage oil space and thereby depressurized.
Die Ventilhülse ist druckausgeglichen, weil der Durchmesser der Führung, in der die Ventilhülse verschiebbar geführt ist, und der Sitzdurchmesser des Ventilsitzes, den die Ventilhülse im Ruhezustand abdichtet, gleich sind. Dadurch entstehen im Ruhezustand keine Druckkräfte in Öffnungs- oder Schließrichtung, sondern lediglich solche in radialer Richtung. Weicht der Sitz- vom Führungsdurchmesser ab, so entstehen dagegen hydraulische Kräfte in axialer Richtung. Sind Führung und Ventilsitz – wie in den meisten Fällen – in einem Bauelement ausgeführt, so kann eine Abweichung des Sitz- vom Führungsdurchmesser jeweils nur derart vorhanden sein, dass hydraulische Kräfte in Öffnungsrichtung entstehen. Im anderen Fall wäre die Ventilhülse nicht mehr in den Ventilkörper fügbar. Damit ist insbesondere der Nachteil verbunden, dass bei einem Flächenangleich im Dichtsitz im Laufe des Betriebs stets nur hydraulische Kräfte in Öffnungsrichtung entstehen können, die im Extremfall zu einem ungewollten Öffnen und damit zu einer Undichtheit des Ventils führen können.The Valve sleeve is pressure balanced because of the diameter the guide, in which the valve sleeve displaceable is guided, and the seat diameter of the valve seat, which seals the valve sleeve at rest, are the same. As a result, no pressure forces occur in the idle state in opening or closing direction, but only those in radial Direction. If the seat deviates from the guide diameter, then In contrast, hydraulic forces occur in the axial direction. Are guide and valve seat - as in most Cases - executed in one component, so can a deviation of the seat from the guide diameter in each case only be present such that hydraulic forces arise in the opening direction. In the other case would be the valve sleeve is no longer in the valve body fügbar. This is associated in particular with the disadvantage that with a surface adjustment in the sealing seat in the course of Always operate only hydraulic forces in the opening direction can arise, which in the extreme case to an unwanted opening and thus lead to a leakage of the valve.
Darüber hinaus sind Konstruktionen bekannt, bei denen die Führung unabhängig vom Ventilsitz in einem zweiten Bauteil ausgeführt ist, welches sich an einem feststehenden Bauteil abstützt. Dies eröffnet zunächst die Möglichkeit, den Sitzdurchmesser auch derart vom Führungsdurchmesser abweichend auszulegen, dass im Ruhestand hydraulische Kräfte in Schließwirkung entstehen. Dies würde bei einem Flächenangleich über Lebensdauer den zulässigen Flächenangleich bis zum Auftreten einer Undichtheit erhöhen und damit auch die Flächenpressung im angeglichenen Zustand senken. Nachteil ist allerdings, dass die hydraulische Schließkraft beim Öffnen des Aktors zusätzlich vom Aktor überwunden werden muss, so dass in diesem Fall ein stärkerer Aktor erforderlich sein wird, was vor allem bei elektromagnetischen Aktoren nachteilig ist.About that In addition, constructions are known in which the leadership regardless of the valve seat executed in a second component is, which is supported on a stationary component. This initially opens the possibility the seat diameter also in such a way from the guide diameter deviating interpreted that retired hydraulic forces arise in closing action. This would be at a Area equal over lifetime the permissible Increase area equal to the occurrence of a leak and thus also the surface pressure in the adjusted state reduce. Disadvantage, however, is that the hydraulic closing force be additionally overcome by the actuator when opening the actuator must, so in this case a stronger actor required will be, which is disadvantageous especially in electromagnetic actuators is.
Offenbarung der ErfindungDisclosure of the invention
Bei dem erfindungsgemäßen Kraftstoffeinspritzventil wirken im Neuzustand keine nennenswerten hydraulischen Kräfte in Axialrichtung auf die Ventilhülse, und dieser kraftausgeglichene Zustand bleibt auch bei einem Flächenangleich zwischen Ventilhülse und Ventilsitz weitgehend erhalten. Dadurch kann bei der Auslegung der Schließfederkraft ein Vorhalt für hydraulische Öffnungskräfte, die im Laufe der Betriebsdauer entstehen, entfallen. In Folge der verringerten Schließfederkraft wird auch der Verschleiß reduziert.at the fuel injection valve according to the invention In the new state, no significant hydraulic forces act in the axial direction on the valve sleeve, and this force-balanced Condition remains even with a surface adjustment between Valve sleeve and valve seat largely preserved. Thereby can in the interpretation of the closing spring force a provision for hydraulic opening forces over the course of Operating time incurred, eliminated. As a result of the reduced closing spring force also the wear is reduced.
