Description
BrennstofforderaggregatFuel ordering unit
Die Neuerung betrifft ein Brennstofförderaggregat
nach dem Oberbegriff des Schutzanspruchs 1.
5The innovation concerns a fuel delivery unit according to the generic term of claim 1.
5
Bei einem derartigen Brennstofförderaggregat (DE-OS 38 40 296) sind Fördermotor und -pumpe in einem Gehäuse angeordnet, das von einem Deckelteil verschlossen ist. Am Deckelteil sind elektrische An-Schlüsse für den Fördermotor vorgesehen sowie ein Anschluß für die Abgabe von Brennstoff und ein Austritt für unter Druck stehenden Brennstoff.In such a fuel feed unit (DE-OS 38 40 296), the feed motor and pump are arranged in a housing that is closed by a cover. The cover has electrical connections for the feed motor as well as a connection for the delivery of fuel and an outlet for pressurized fuel.
Anschluß und Austritt weisen jeweils eine Ventilan-Ordnung auf, die von außen in das Deckelteil eingefügt
wurde. Die elektrischen Anschlüsse für den Fördermotor ragen aus dem Inneren des Gehäuses
durch das Deckelteil hindurch, wobei spezielle Abdichtungen nicht vorgesehen sind.
20The connection and outlet each have a valve arrangement that has been inserted into the cover part from the outside. The electrical connections for the conveyor motor protrude from the inside of the housing through the cover part, whereby special seals are not provided.
20
Der Neuerung liegt die Aufgabe zugrunde, bei einem Brennstofförderaggregat der angegebenen Art eine Ausführung zu schaffen, bei der das Deckelteil derart beschaffen ist, daß eine problemfreie Montage, leckagefreie Abdichtung sowie einfache Ausführung des Deckelteils erreichbar werden.The innovation is based on the task of creating a design for a fuel feed unit of the specified type in which the cover part is designed in such a way that problem-free assembly, leak-free sealing and simple design of the cover part can be achieved.
Diese Aufgabe ist bei dem angegebenen Brennstofförderaggregat durch die kennzeichnenden Merkmale des Schutzanspruchs 1 gelöst worden.This task has been solved in the fuel delivery unit specified by the characterizing features of claim 1.
Vorteilhafte Weiterbildungen des Gegenstandes der Neuerung sind mit den Unteransprüchen angegeben.Advantageous further developments of the subject matter of the innovation are specified in the subclaims.
Mit der Neuerung erzielbare Vorteile sind in der nachfolgenden Beschreibung eines in der Zeichnung dargestellten Ausführungsbeispiels angegebenThe advantages that can be achieved with the innovation are indicated in the following description of an embodiment shown in the drawing.
S.p.
Die Zeichnung zeigt in Fig. 1 einen Längsschnitt durch ein neuerungsgemäßes Brennstofförderaggregat, wie es für den Einsatz als Innentankpumpe bei einem Kraftfahrzeug vorgesehen ist, und Fig. 2 ein Einzelteil. The drawing shows in Fig. 1 a longitudinal section through a fuel feed unit according to the innovation, as it is intended for use as an internal tank pump in a motor vehicle, and Fig. 2 an individual part.
Das Brennstofförderaggregat 1 besteht aus einem Gehäuse 2, in dem wenigstens eine Förderpumpe 3 und ein diese antreibender elektrischer Fördermotor 4 angeordnet sind. Das Gehäuse 2 ist von einem äußeren Deckelteil 5 verschlossen, das elektrische Anschlüsse 6 (Fig. 2) für den Fördermotor 4, einen Anschluß 7 für die Abgabe des Brennstoff sowie einen Austritt 8 für unter Druck stehenden Brennstoff aufweist. Der Anschluß 7 weist ein Plattenventil 9 auf, das unter Federkraft gegen einen Ventilsitz 10 belastet ist. Der Ventilsitz 10 ist mittels eines Elastomer-Dichtringes 11 in das Deckelteil 5 eingespannt und wird durch ein gegen das Deckelteil 5 angelegtes, inneres Deckelteil 12 gesichert, wobei das Deckelteil 12 im Bereich des Ventilsitzes 10 als Sieb 13 ausgebildet ist.The fuel feed unit 1 consists of a housing 2 in which at least one feed pump 3 and an electric feed motor 4 driving it are arranged. The housing 2 is closed by an outer cover part 5 which has electrical connections 6 (Fig. 2) for the feed motor 4, a connection 7 for the delivery of the fuel and an outlet 8 for pressurized fuel. The connection 7 has a plate valve 9 which is spring-loaded against a valve seat 10. The valve seat 10 is clamped into the cover part 5 by means of an elastomer sealing ring 11 and is secured by an inner cover part 12 which is placed against the cover part 5, whereby the cover part 12 is designed as a sieve 13 in the area of the valve seat 10.
Der Austritt 8 für unter Druck stehenden Brennstoff weist einen Ventilsitzeinsatz 14 auf, der in das äußere Deckelteil 5 eingeklipst ist und ebenfalls von dem inneren Deckelteil 12 gesichert ist. Der Ventilsitzeinsatz 14 führt eine Kugel 15 sowie eine Feder 16 in bezug auf den Ventilsitz. Der Ventilsitzeinsatz 14 weist im Bewegungsabschnitt der Kugel 15 einen kalibrierten Durchmesser auf, so daß die Kugel 15 als Proportionalventil wirkt, d. h. der Drosselspalt wandert mit der Kugel 15, so daß der unter Druck stehende Brennstoff mit der Öffnungsbewegung der Kugel unter steigendem Druck verbleibt. The outlet 8 for pressurized fuel has a valve seat insert 14 which is clipped into the outer cover part 5 and is also secured by the inner cover part 12. The valve seat insert 14 guides a ball 15 and a spring 16 in relation to the valve seat. The valve seat insert 14 has a calibrated diameter in the movement section of the ball 15 so that the ball 15 acts as a proportional valve, i.e. the throttle gap moves with the ball 15 so that the pressurized fuel remains under increasing pressure with the opening movement of the ball.
S.p.
Fig. 2 zeigt das innere Deckelteil 12 als Einzelteil, aus dem ersichtlich ist, daß die elektrischen Anschlüsse 6 durch einen zylindrischen Zapfen 16 hindurchtreten und über Schlitze 17 des äußeren Deckels 5 in einen Steckerschaft 18 des äußeren Deckels 5 hineinragen. Die zylindrischen Zapfen 16 weisen in äußeren Nuten 19 Elastomerdichtungen 20 auf, die mit zylindrischen Ausnehmungen 21 des äußeren Deckelteils 5 dichtend zusammenwirken. Die elektrischen Anschlüsse 6 sind mit einer Funkentstördrossel bzw. einem Funkentstörkondensator 22 verbunden.Fig. 2 shows the inner cover part 12 as a single part, from which it can be seen that the electrical connections 6 pass through a cylindrical pin 16 and protrude into a plug shaft 18 of the outer cover 5 via slots 17 of the outer cover 5. The cylindrical pins 16 have elastomer seals 20 in outer grooves 19, which interact sealingly with cylindrical recesses 21 of the outer cover part 5. The electrical connections 6 are connected to a radio interference suppression choke or a radio interference suppression capacitor 22.
Die neuerungsgemäße Ausführung des Brennstofförderaggregats ermöglicht eine einfache Montage, leckagefreie Abdichtung der elektrischen Anschlüsse und eine einfache Ausführung der Deckelteile, so daß insgesamt eine kostengünstige Herstellung erreichbar ist, womit der Einsatz in einem Kraftfahrzeug gegeben sein kann.The new design of the fuel feed unit enables easy assembly, leak-free sealing of the electrical connections and a simple design of the cover parts, so that overall cost-effective production is achievable which means that it can be used in a motor vehicle.
