Abstract
Drehkolbenpumpe mit einem Zylindertopf und einem Flanschkörper, in welchem ein Rotor gelagert ist, der aus wenigstens drei Teilen, die miteinander verschweisst sind, hergestellt ist, von denen zwei identisch geformt sind, und der einen durch eine Rotordrehmitte verlaufenden in einer Axialebene angeordneten Schlitz aufweist, in dem ein durchgehender Schieber angeordnet und geführt ist, und wobei eine Querschnittsfläche des Zylindertopfes eine Zylinderwandkurve bildet, die derart geformt ist, dass alle Sekanten an die Zylinderwandkurve, die durch die Rotordrehmitte verlaufen, im wesentlichen gleich der Schieberlänge sind, dadurch gekennzeichnet, dass das dritte Rotorteil (18) durch Formschluß die beiden identischen Rotorteile (16, 17) in einer fest vorgegebenen Position zueinander fixiert.Rotary lobe pump with a cylinder pot and a flange body, in which a rotor is mounted, which is made of at least three parts which are welded together, two of which are identically shaped, and which has a slot arranged in an axial plane and running through a rotor center of rotation, in which a continuous slide is arranged and guided, and wherein a cross-sectional area of the cylinder pot forms a cylinder wall curve which is shaped such that all secants on the cylinder wall curve which pass through the center of rotation of the rotor are substantially equal to the slide length, characterized in that third rotor part (18) fixes the two identical rotor parts (16, 17) to one another in a fixed predetermined position.
Description
Die Erfindung betrifft eine Drehkolbenpumpe mit einem zwangsläufig geführten Schieber unveränderlicher Länge nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a rotary lobe pump one inevitably out Slider unchangeable Length after the preamble of claim 1.
Eine solche Drehkolbenpumpe kann von einer Fahrzeugantriebsmaschine angetrieben werden und ein Fluid fördern, insbesondere Luft zur Vakuum- oder Drucklufterzeugung für Fahrzeughilfsaggregate.Such a rotary lobe pump can powered by a vehicle engine and a fluid promote, in particular air for vacuum or compressed air generation for vehicle auxiliary units.
Aus den Schriften
Durch Ausgestaltung des Gehäuses als Kochoidengehäuse und
durch eine angepasste Ausgestaltung der Schieberenden wird die Konstruktion eines
Drehkolbenverdichters mit nur einem Schieber gemäß
Darüber hinaus liegt auch mit dem
Gegenstand der
Es ist daher Aufgabe der Erfindung, ausgehend von einer gattungsgemäßen Drehkolbenpumpe, diese derart zu gestalten, dass eine vorteilhafte kostensparende Fertigung und eine lange Lebensdauer erreicht werden.It is therefore an object of the invention starting from a generic rotary lobe pump, to design them in such a way that an advantageous cost-saving Manufacturing and long life can be achieved.
Diese Aufgabe ist mit den im Kennzeichen des Anspruches 1 angegebenen Merkmalen gelöst worden. Vorteilhafte Weiterbildungen sind mit den Unteransprüchen angegeben.This task is with the in the characteristics of the Claim 1 specified features have been solved. Advantageous further training are with the subclaims specified.
