Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Pumpe, insbesondere Kraftstoffhochdruckpumpe nach der Gattung des Anspruchs 1.The Invention is based on a pump, in particular high-pressure fuel pump according to the preamble of claim 1.
Eine
solche Pumpe in Form einer Kraftstoffhochdruckpumpe ist durch die
Aus
der
Will man bei einer derartigen Pumpe das Pumpengehäuse zwecks Gewichtersparnis aus Aluminium herstellen, ist es bekannt, eine spezielle Wärmebehandlung und/oder eine Harteloxierung des Pumpengehäuses durchzuführen, um die geforderte Dauerhaltbarkeit zu erzielen. Hierdurch werden hohe Fertigungskosten verursacht.Want in such a pump, the pump housing in order To save weight from aluminum, it is known to have a special heat treatment and / or hard anodizing perform the pump housing to the required durability to achieve. This causes high production costs.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Pumpe mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass die Antriebswelle direkt im Pumpengehäuse gelagert werden kann und eine spezielle Lagerung über eine Lagerbuchse entfällt. Dies hat Vorteile hinsichtlich des Gewichts und der Fertigungskosten. Da die Oberfläche des Pumpengehäuses nicht durch Beschichtung, sondern durch Umwandlung in eine Aluminiumoxidkeramik gehärtet ist, ergeben sich Vorteile hinsichtlich der Maßhaltigkeit.The Pump according to the invention with the features of claim 1 has the advantage that the drive shaft can be stored directly in the pump housing and a special Storage via a bearing bush is eliminated. This has advantages in terms of weight and manufacturing costs. There the surface of the pump housing not by coating, but cured by conversion to an alumina ceramic is, there are advantages in dimensional accuracy.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Pumpe angegeben.In the dependent claims are advantageous embodiments and further developments of the pump according to the invention specified.
