Abstract
Description
Technisches GebietTechnical area
Die Erfindung geht aus von einer Einspritzpumpe, insbesondere von einer Einspritzpumpe nach dem Oberbegriff von Anspruch 1.The The invention is based on an injection pump, in particular of a Injection pump according to the preamble of claim 1.
Stand der TechnikState of the art
Eine
solche Einspritzpumpe ist aus der
Mit der bekannten Einspritzpumpe lassen sich nur unzureichend hohe Drücke dauerhaft erzielen. Es entstand daher der Wunsch eine solche Einspritzpumpe derart weiter zu entwickeln, dass sich Drücke von mehr als 2000 bar dauerhaft damit erzielen lassen.With the known injection pump can only insufficiently high pressures permanently achieve. It was therefore the desire of such an injection pump so continue to develop, that pressures of more than 2000 permanently with it.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Einspritzpumpe mit den Merkmalen gemäß Anspruch 1 hat den Vorteil, dass sich auf lange Zeit hohe Einspritzdrücke von mehr als 2000 bar nahezu verschleißfrei erzielen lassen.The injection pump according to the invention with the features according to claim 1 has the advantage that on long high injection pressures of more than 2000 bar almost can be achieved wear-free.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Einspritzpumpe angegeben.In the dependent claims are advantageous embodiments and further developments of the injection pump according to the invention specified.
Durch die Ausbildung gemäß Anspruch 2 ergibt sich eine statisch stabilere Lagerung des Kolbens in dem Gehäuse, was maßgeblich dazu beiträgt, Schwingungen der Antriebswelle zu vermeiden. Für eine Verbesserung des Verschleißverhaltens und die Erzielung höchster Drücke ist das von großem Vorteil.By the training according to claim 2 results in a statically more stable bearing of the piston in the housing, which contributes significantly to vibrations of the Drive shaft to avoid. For an improvement of the wear behavior and the achievement of highest pressures is that of great Advantage.
Durch die Ausbildung gemäß Anspruch 3 wird ausgeschlossen, dass von der Antriebswelle sich parallel zu ihrer Längsrichtung wirksame Kräfte auf den Kolben übertragen werden können. Die Abdichtung des Kolbens in dem ihn aufnehmenden Zylinder wird dadurch vereinfacht. Außerdem ist das ist für die Dauerhaltbarkeit der Einspritzpumpe von großem Vorteil.By the training according to claim 3 is excluded, that of the drive shaft is parallel to its longitudinal direction effective forces are transmitted to the piston can. The seal of the piston in the receiving him Cylinder is simplified. Besides, that's for the durability of the injection pump of great advantage.
In der Ausbildung gemäß Anspruch 4 wird eine Einspritzpumpe gezeigt, die es erlaubt, je Umdrehung der Antriebswelle einen Pumpenhub zu erzielen.In The embodiment according to claim 4 is an injection pump shown, which allows a pump stroke per revolution of the drive shaft to achieve.
In der Ausbildung gemäß Anspruch 5 wird eine Einspritzpumpe gezeigt, die es erlaubt, je Umdrehung der Antriebswelle zwei Pumpenhübe zu erzielen und auf diese Weise die Förderleistung der Einspritzpumpe zu verdoppeln.In The embodiment according to claim 5 is an injection pump shown, which allows two pump strokes per revolution of the drive shaft to achieve and in this way the delivery rate of the injection pump to double.
