Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Einspritzpumpe mit den Merkmalen gemäß Anspruch 1 hat den Vorteil einer wesentlich verbesserten Drehfestigkeit. Die Baugröße kann dadurch verringert und die Einspritzpumpe mit höherer Drehzahl betrieben werden als bisher, um das für den Betrieb der angeschlossenen Verbrennungskraftmaschine benötigte Fördervolumen zu erreichen. Hieraus resultiert nicht nur eine Verminderung der Herstellkosten und des Gewichtes der Einspritzpumpe, sondern auch eine Verminderung der betriebsbedingten Leckage. Ein Totalausfall der Einspritzpumpe in Folge Federbruchs ist auch bei höheren Drehzahlen nicht mehr zu befürchten.The injection pump according to the invention with the features according to claim 1 has the advantage of a significant improved torsional strength. The size can thereby reducing and the injection pump at a higher speed be operated as before, in order for the operation of the connected internal combustion engine required delivery volume to reach. This not only results in a reduction of the Production costs and the weight of the injection pump, but also a reduction of operational leakage. A total failure of Injection pump in a row Spring break is also at higher Speeds no longer to be feared.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Vorrichtung angegeben.In the dependent claims are advantageous embodiments and further developments of the device according to the invention specified.
Durch die Ausgestaltung nach Anspruch 2 wird eine Verringerung der im schwingfähigen Teil der Bügelfeder kumulierten Trägheitsmassen und damit eine Verlagerung der Resonanzfrequenz der Bügelfeder in unkritische Drehzahlbereiche erzielt. Die Drehzahl der Einspritzpumpe kann dadurch noch weiter erhöht werden.By The embodiment according to claim 2, a reduction in the oscillatory part of the bow spring accumulated Inertia masses and thus a shift of the resonance frequency the bow spring achieved in uncritical speed ranges. The speed of the injection pump can thereby further increased become.
Die Ausgestaltung nach Anspruch 3 hat den Vorteil, dass sich die Blattfeder besonders einfach herstellen und montieren lässt.The Embodiment according to claim 3 has the advantage that the leaf spring particularly easy to manufacture and assemble.
Die Ausgestaltung nach Anspruch 4 hat den Vorteil, dass sich eine weitere Verminderung der Herstellkosten der Bügelfeder ergibt sowie eine extrem hohe Resonanzfrequenz der darin im montierten Zustand enthaltenen, schwingfähigen Massenanteile.The Embodiment according to claim 4 has the advantage that a further Reduction of the manufacturing costs of the bow spring results as well an extremely high resonance frequency of it in the mounted state contained, oscillatory mass fractions.
Die Ausgestaltung nach Anspruch 5 hat den Vorteil, dass sich die Pumpenleistung unter Vermeidung nennenswerter Mehrkosten in der Herstellung der Einspritzpumpe bei im wesentlichen gleichbleibendem Gewicht verdoppelt. Um eine bestimmtes Fördervolumen zu erzielen, kann die Baugröße folglich noch weiter vermindert werden.The Embodiment according to claim 5 has the advantage that the pump power while avoiding significant additional costs in the production of Injection pump doubled at substantially constant weight. To achieve a certain volume, the Frame size can therefore be further reduced.
Die Ausgestaltung nach Anspruch 6 hat den Vorteil, dass sich die Fördervolumina beider Pumpenzylinder in Bezug auf die Versorgung eines gemeinsamen Hochdruckspeichers addieren. Dies vereinfacht die Steuerung ganz wesentlich in Hinblick auf die Erzielung optimaler Verbrennungsvorgänge in der angeschlossenen Verbrennungskraftmaschine.The Embodiment according to claim 6 has the advantage that the delivery volumes Both pump cylinders with respect to the supply of a common Add high-pressure accumulator. This simplifies the control completely essential in terms of achieving optimal combustion processes in the connected internal combustion engine.
