Solche G-Rotorpumpen werden meist mit einem Elektromotor zu einer Fördereinheit zusammengesetzt und sind aus der Praxis bekannt . Die bekannte G-Rotorpumpe hat im Deckel einen Ein- lasskanal und im dem Elektromotor zugewandten Boden einen Auslasskanal. Hierdurch wird die G-Rotorpumpe axial durchströmt. Der Abstandhalter ist im Wesentlichen ringförmig, den G-Rotor umschließend gestaltet und hält den Deckel auf einem vorgesehenen Abstand zum Boden. Damit können der Boden und der Deckel gegeneinander verspannt sein. Der Deckel, derSuch G rotor pumps are usually assembled with an electric motor to form a delivery unit and are known in practice. The known G rotor pump has an inlet channel in the cover and an outlet channel in the bottom facing the electric motor. This flows axially through the G rotor pump. The spacer is essentially ring-shaped, surrounds the G-rotor and holds the lid at a designated distance from the floor. So that the bottom and the lid can be braced against each other. The lid that
G-Rotor, der Boden und der Abstandhalter sind aus Keramik mit einer besonders hohen Oberflächengüte gefertigt. Durch die hohe Oberflächengüte wird sichergestellt, dass ein Überströmen des geförderten Kraftstoffs von dem Bereich des Auslasses zu dem Bereich des Einlasses vermieden wird.G-rotor, the base and the spacer are made of ceramic with a particularly high surface quality. The high surface quality ensures that an overflow of the delivered fuel from the area of the outlet to the area of the inlet is avoided.
Nachteilig bei der bekannten G-Rotorpumpe ist, dass das Pumpengehäuse sehr aufwändig gestaltet ist und damit kostenintensiv zu fertigende Bauteile aufweist.A disadvantage of the known G rotor pump is that the pump housing is designed to be very complex and thus has components which are cost-intensive to manufacture.
Der Erfindung liegt das Problem zugrunde, eine G-Rotorpumpe der eingangs genannten Art so zu gestalten, dass sie besonders kostengünstig zu fertigen ist. The invention is based on the problem of designing a G rotor pump of the type mentioned at the outset in such a way that it can be manufactured particularly cost-effectively.
Dieses Problem wird erfmdungsgemaß dadurch gelost, dass der Boden und/oder der Deckel aus Kunststoff gefertigt sind/ist.According to the invention, this problem is solved in that the base and / or the cover are / are made of plastic.
Durch diese Gestaltung lasst sich das Pumpengehause aus be- sonders kostengünstig zu fertigenden Bauteilen zusammensetzen. Die erfmdungsgemaße G-Rotorpumpe lasst sich hierdurch besonders kostengünstig fertigen. Ein weiterer Vorteil der erfmdungsgemaßen G-Rotorpumpe besteht darin, dass Geräusche des G-Rotors durch die aus Kunststoff gefertigten Bauteile des Pumpengehauses besonders stark gedampft werden.With this design, the pump housing can be assembled from components that can be manufactured particularly cost-effectively. The G rotor pump according to the invention can thereby be manufactured particularly cost-effectively. Another advantage of the G-rotor pump according to the invention is that noises of the G-rotor are particularly strongly dampened by the plastic components of the pump housing.
Die für den zuverlässigen Betrieb der erfmdungsgemaßen G-Rotorpumpe erforderliche hohe Oberflachengute konnte beispielsweise durch eine Beschichtung des Bodens und/oder des Deckels erreicht werden. Zur weiteren Verringerung der Fertigungskosten der erfmdungsgemaßen G-Rotorpumpe tragt es [jedoch bei, wenn der Boden und/oder der Deckel auf ihrer dem G-Rotor gegen berstehenden Seite gelappt sind/ist. Zur Vereinfachung der Montage der erfmdungsgemaßen G-Rotorpumpe tragt es bei, wenn der Abstandhalter emstuckig mit dem auf der einem elektrischen Antrieb abgewandten Seite des G-Rotors angeordneten Deckel gefertigt ist. Hierdurch kann der auf der einem elektrischen Antrieb zugewandten Seite des G-Rotors angeordnete Boden eben gestaltet sein. Dies tragt zur weiteren Verringerung der Fertigungskosten der erfmdungsgemaßen G-Rotorpumpe bei.The high surface quality required for the reliable operation of the G-rotor pump according to the invention could be achieved, for example, by coating the bottom and / or the cover. It contributes to a further reduction in the manufacturing costs of the G-rotor pump according to the invention [however, if the base and / or the cover are / are lobed on their side opposite the G-rotor. To simplify the assembly of the G-rotor pump according to the invention, it helps if the spacer is made in one piece with the cover arranged on the side of the G-rotor facing away from an electric drive. As a result, the base arranged on the side of the G rotor facing an electric drive can be designed to be flat.

Der Abstandhalter 6 und der Deckel 7 sind hier einstückig gefertigt. Zwischen dem Deckel 7 und dem Boden 5 ist ein auf einer Welle 8 des Elektromotors 4 befestigter G-Rotor 9 angeordnet. Die Welle 8 weist zur drehfesten Mitnahme des G-Rotors 9 eine Abflachung 10 auf. Die Welle 8 hat zudem im Bereich des G-Rotors 9 einen Absatz 11. Hierdurch ist der G-Rotor 9 nur in der eingezeichneten Lage mit der Welle 8 verbindbar. Der Deckel 7 weist einen Einlass 12 und der Boden 5 einen Auslass 13 der G-Rotorpumpe 2 auf. Hierdurch wird Kraftstoff über den Deckel 7 angesaugt und die G-Rotorpumpe 2 axial durchströmt. Das Gehäuse 3 der Kraftstofffördereinheit 1 hat einen Anschlussstutzen 14 zum An- schluss einer nicht dargestellten Leitung. Zur Verdeutlichung sind in der Zeichnung die Strömungen des Kraftstoffs mit Pfeilen gekennzeichnet.The fuel delivery unit 1 has a housing 3 for accommodating an electric motor 4 and the G-rotor pump 2. The G-rotor pump 2 has a base 5 and a cover 7, which is kept at a predetermined distance from the base 5 via a spacer 6. The spacer 6 and the cover 7 are made in one piece here. A G rotor 9, which is fastened on a shaft 8 of the electric motor 4, is arranged between the cover 7 and the base 5. The shaft 8 has a flattened portion 10 for the rotationally fixed entrainment of the G rotor 9. The shaft 8 also has a shoulder 11 in the region of the G rotor 9. As a result, the G rotor 9 can only be connected to the shaft 8 in the position shown. The cover 7 has an inlet 12 and the base 5 has an outlet 13 of the G rotor pump 2. As a result, fuel is drawn in via the cover 7 and the G-rotor pump 2 flows axially. The housing 3 of the fuel delivery unit 1 has a connecting piece 14 for connecting a line, not shown. For clarity, the flows of the fuel are marked with arrows in the drawing.
Der Deckel 7 und der Boden 5 sind aus Kunststoff gefertigt und auf ihrer dem G-Rotor 9 zugewandten Seite geläppt. Hierdurch weisen der Deckel 7 und der Boden 5 eine besonders hohe Oberflächengüte auf und vermögen Geräusche zuverlässig zu dämmen .The cover 7 and the base 5 are made of plastic and lapped on their side facing the G rotor 9. As a result, the cover 7 and the base 5 have a particularly high surface quality and are able to reliably dampen noise.
Weiterhin hat die G-Rotorpumpe 2 zwei Schrauben 15, die den Deckel 7 gegen den Boden 5 vorspannen. In einer alternativen, nicht dargestellten Ausführungsform ist der Deckel 7 über das Gehäuse 3 der Kraftstofffördereinheit gegen den Boden 5 vorgespannt. Damit lässt sich auf die Verwendung der Schrauben 15 verzichten. Furthermore, the G-rotor pump 2 has two screws 15 which pretension the cover 7 against the base 5.
