Description
Technisches GebietTechnical area
Die Erfindung geht aus von einer Steckpumpe für eine Verbrennungskraftmaschine, insbesondere von einer Steckpumpe nach dem Oberbegriff von Anspruch 1.The Invention is based on a plug-in pump for an internal combustion engine, in particular of a plug-in pump according to the preamble of claim 1.

Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Kraftstoffhochdruckpumpe mit den Merkmalen gemäß Anspruch 1 hat den Vorteil, dass es völlig ausgeschlossen ist, dass Kraftstoff in das Schmieröl einer Verbrennungskraftmaschine gelangt.The inventive high-pressure fuel pump with the features according to claim 1 has the advantage that it is completely excluded that fuel in the Lubricating oil of an internal combustion engine passes.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Kraftstoffhochdruckpumpe angegeben.In the dependent claims are advantageous embodiments and further developments of the high-pressure fuel pump according to the invention specified.
Durch die Ausbildung gemäß Anspruch 2 wird eine Steckpumpe für eine Verbrennungskraftmaschine gezeigt, die es erlaubt, die Leckageleitung besonders einfach und platzsparend herzustellen.By The embodiment according to claim 2 is a plug-in pump shown for an internal combustion engine that allows make the leakage line particularly simple and space-saving.
Durch die Ausbildung gemäß Anspruch 3 genügt ein besonders kleiner Faltenbalg zu Erzielung des erfindungsgemäßen Zweckes, eine wirksame Trennung der mit Kraftstoff und mit Schmieröl in Verbindung gelangenden Räume der Steckpumpe und der Verbrennungskraftmaschine zu gewährleisten.By the training according to claim 3 is sufficient a particularly small bellows to achieve the invention Purpose, an effective separation of fuel and lubricating oil communicating spaces of the plug-in pump and the Ensuring internal combustion engine.
Durch die Ausbildung gemäß Anspruch 4 wird eine besonders einfache und hochwirksame Abdichtung des die Leckageleitung in einem Teilbereich abdeckenden Blechzylinders erzielt.By the training according to claim 4 becomes a special simple and highly effective sealing of the leakage line in one Partial area covering sheet cylinder achieved.
Durch die Ausbildung gemäß Anspruch 5 wird erzielt, dass sich unter der Wirkung der vorgespannten Druckfeder im uneingebauten Zustand der Steckpumpe keine unzulässige Dehnbeanspruchung des Faltenbalges ergeben an. Insbesondere in bezug auf die Vermeidung von Lagerschäden ist das von großem Vorteil. Außerdem sind die verschiedenen Einzelteile der Steckpumpe durch die wenigstens eine Sicherungsschraube gegen ein unbeabsichtigtes Auseinanderfallen bei der Lagerung oder beim dem Transport gesichert, was dazu beiträgt Montagefehler zu vermeiden.By the training according to claim 5 is achieved that under the action of the prestressed compression spring in uninhabited Condition of the plug - in pump no undue strain on the Bellows result. Especially with regard to avoidance This is a great advantage of bearing damage. Furthermore are the various items of the plug-in pump through the at least one Securing screw against unintentional falling apart secured during storage or during transport, which contributes To avoid assembly errors.
Der Hohlzylinder kann naturgemäss unabhängig von dem Zylinderkopf gefertigt und beispielsweise durch nachträgliches Einschrauben eines Hohlzylinders mit dem Zylinderkopf verbunden werden. Die Ausbildung gemäß Anspruch 6 zeigt demgegenüber eine besonders günstige Herstellbarkeit der Steckpumpe, bei der der nachträglich Montageprozess entfällt.Of the Hollow cylinder can, of course, regardless of the Cylinder head manufactured and, for example, by subsequent Screw in a hollow cylinder connected to the cylinder head become. The training according to claim 6 shows In contrast, a particularly favorable manufacturability the plug-in pump, during the subsequent assembly process eliminated.
Durch die Ausbildung gemäß Anspruch 7 zeigt eine Bauform, bei der der Faltenbalg besonders kostengünstig herstell- und montierbar ist. Die Flexibilität eines aus polymerem Werkstoff bestehenden des Faltenbalges ist außerdem besonders groß, d. h. es sind keine nennenswerten Kräfte für die Dehnungen und Zusammendrückungen nötig, die der Betrieb einer Steckpumpe erfordert. Dem Wunsch nach einer Verringerung des Kraftstoffverbrauchs kommt das entgegen.By the embodiment according to claim 7 shows a design, in which the bellows are produced at particularly low cost and mountable. The flexibility of a polymeric Material of the bellows is also special big, d. H. they are not significant forces necessary for stretching and squeezing which requires the operation of a plug-in pump. The desire for a reduction the fuel consumption is the opposite.
Die Ausbildung gemäß Anspruch 8 hat den Vorteil einer besonders großen thermischen und mechanischen Beständigkeit. Sie gelangt vor allem in hochbelasteten Motoren zur Anwendung.The Training according to claim 8 has the advantage of particularly high thermal and mechanical resistance. It is mainly used in highly loaded engines.
Durch die Ausbildung gemäß Anspruch 9 gelingt es, einen aus Metall bestehenden Faltenbalg und einen aus dem gleichen Metall bestehenden Kolben bzw. der daran festgelegten Tasse, sehr schnell zu verbinden, ohne dass sich kritische Spannungen oder Verformungen der Teile ergeben. Die Teile bestehen bevorzugt aus kostengünstigem Stahl.By the training according to claim 9 succeeds, a made of metal bellows and one of the same metal existing piston or the cup fixed thereto, very fast too connect without causing critical stresses or deformations the parts result. The parts are preferably made of inexpensive Stole.
