Abstract

In order to prevent fuel escaping in the event of a crash irrespective of whether the internal combustion engine of the vehicle continues to run or not, a safety device (6, 8, 18) is provided, which utilises forces occurring in the event of a crash to render the fuel pump (1, 10) inoperative (Fig. 1). <IMAGE>

Description

Die Erfindung betrifft eine Kraftstoffversorgung gemäß dem Oberbegriff des Patent­ anspruchs 1.The invention relates to a fuel supply according to the preamble of the patent claim 1.

Im Crashfall, worunter im Rahmen der Erfindung jeder zu Beschädigungen des Fahr­ zeugs, so daß dieses nicht mehr fahrtüchtig ist, führende Unfall zu verstehen ist, be­ steht bekanntlich die Gefahr, daß auslaufender Kraftstoff auf heiße Teile der Brenn­ kraftmaschine fließt und sich dort entzündet. Diese Problematik ist altbekannt; zur Lösung des Problems in der Patentliteratur vorgeschlagene Sicherheitseinrichtungen erfassen das Ausbleiben von Zündimpulsen oder den Stillstand des von der Brennkraft­ maschine angetriebenen Generators als Indiz für den Stillstand der Brennkraftmaschine und schalten dann die Kraftstoffpumpe ab (DE-OS 23 44 705, F 02 M 37/08; DE-AS 25 57 669, F 04 B 49/06; US-PS 30 68 364).In the event of a crash, including any damage to the driver in the context of the invention stuff, so that this is no longer roadworthy, leading accident can be understood, be there is a known risk that leaking fuel on hot parts of the burner engine flows and ignites there. This problem is well known; to Solving the problem of safety devices proposed in the patent literature detect the absence of ignition pulses or the standstill of the internal combustion engine machine driven generator as an indication of the standstill of the internal combustion engine and then switch off the fuel pump (DE-OS 23 44 705, F 02 M 37/08; DE-AS 25 57 669, F 04 B 49/06; U.S. Patent 30 68 364).

Diese Sicherheitseinrichtungen versagen jedoch in der nicht geringen Anzahl von Crash­ fällen, in denen die Brennkraftmaschine trotz Leckagen in ihrer Kraftstoffversorgung weiterläuft. In diesen Fällen sind die vorgeschlagenen Sicherheitseinrichtungen völlig wirkungslos, und man kann sagen, daß die Kraftstoffpumpe die unfallbedingten Lecka­ gen weiter mit Kraftstoff versorgt.However, these safety devices fail in the not insignificant number of crashes cases in which the internal combustion engine despite leaks in its fuel supply continues. In these cases, the proposed safety devices are complete ineffective, and it can be said that the fuel pump caused the accidental leak gen continues to be supplied with fuel.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine Kraftstoffversorgung gemäß dem Oberbegriff des Patentanspruchs 1 so auszubilden, daß im Crashfall auch bei zu­ nächst weiterlaufender Brennkraftmaschine die Pumpe schnellstens unwirksam gemacht wird. The invention is accordingly based on the object of providing a fuel supply to form the preamble of claim 1 so that in the event of a crash the next time the internal combustion engine continues to run, the pump is quickly deactivated becomes.  

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkma­ len des Hauptanspruchs, vorteilhafte Ausbildungen der Erfindung beschreiben die Unter­ ansprüche.The solution to this problem according to the invention consists in the characteristic features len of the main claim, advantageous embodiments of the invention describe the sub Expectations.

Die Erfindung geht also von dem bisher angewendeten Prinzip der Abschaltung der Kraftstoffpumpe nur dann, wenn die Brennkraftmaschine bei dem Unfall zum Stillstand gekommen ist, ab und sieht eine Sicherheitseinrichtung vor, die die crashbedingten Trägheits- oder Aufprallkräfte ausnutzt, um die Pumpe durch Abschalten derselben oder durch Unterbrechen der Vorlaufleitung unwirksam zu machen.The invention is therefore based on the principle of switching off the previously applied Fuel pump only if the internal combustion engine comes to a standstill in the accident has come, and provides a safety device that the crash-related Inertial or impact forces are used to stop the pump by turning it off or ineffective by interrupting the flow line.

Wie auch die Unteransprüche zum Ausdruck bringen, ist ein besonderer Vorteil der Er­ findung darin zu sehen, daß der Aufwand für die Sicherheitseinrichtung außerordentlich gering ist.As the subclaims also express, he is a particular advantage finding that the effort for the safety device is extraordinary is low.

Soweit die Verwendung von Crashsensoren vorgesehen sind, die elektrische Stromkreise unterbrechen, sei darauf hingewiesen, daß derartige Sensoren in unterschiedlichen Aus­ bildungen, beispielsweise auch in Gestalt von Detonationssensoren, bekannt sind; siehe nur die US-PS 39 88 027, B 62 D 1/18. Auch in dieser Hinsicht erfordert die Erfindung also keine Neukonstruktion irgendwelcher Bauelemente oder Bauteile.As far as the use of crash sensors are provided, the electrical circuits interrupt, it should be noted that such sensors in different Aus formations, for example also in the form of detonation sensors, are known; please refer only US-PS 39 88 027, B 62 D 1/18. The invention also requires in this regard So no redesign of any components or parts.

Mehrere Ausführungsbeispiele der Erfindung werden im folgenden anhand der Figuren erläutert, von denenSeveral embodiments of the invention are described below with reference to the figures explained, of which

Fig. 1 die wesentlichen Bestandteile eines Ansteuerstromkreises für die Kraftstoffpumpe und Fig. 1 shows the essential components of a control circuit for the fuel pump and

Fig. 2 einen Axialschnitt durch einen mit einer Innen­ pumpe bestückten Kraftstofftank wiedergeben. Fig. 2 show an axial section through a fuel tank equipped with an internal pump.

Betrachtet man zunächst Fig. 1, so liegt die Kraftstoffpumpe 1 in einem die Fahrzeug­ batterie 2 und den Kontakt 3 des Kraftstoffpumpenrelais 4 enthaltenden Stromkreis. Die eigentliche Ansteuerschaltung für das Pumpenrelais 4 und damit die Pumpe 1, die bei­ spielsweise einen Zündkontakt enthält, interessiert hier im einzelnen nicht und ist daher lediglich als Block bei 5 angedeutet.Looking first at Fig. 1, the fuel pump 1 is in a vehicle battery 2 and the contact 3 of the fuel pump relay 4 containing circuit. The actual control circuit for the pump relay 4 and thus the pump 1 , which for example contains an ignition contact, is of no interest here and is therefore only indicated as a block at 5 .

In der Verbindungsleitung zwischen diesem Block 5 einerseits und dem Pumpenrelais 4 andererseits erkennt man den Kontakt 6 eines Crashsensors, der ferner einen nicht ge­ zeichneten, da an sich bekannten Auslösekontakt enthält, der beim Auftreten crashbe­ dingter Kräfte einen den Kontakt 6 zerstörenden oder öffnenden Impuls erzeugt. Unab­ hängig davon, ob in dem betrachteten Crashfall die Brennkraftmaschine des Fahrzeugs sofort zum Stillstand kommt oder weiterläuft, erfolgt also durch Unterbrechung der Ver­ bindung zwischen Block 5 und Pumpenrelais 4 schnellstens das Öffnen des Kontakts 3 und damit die Abschaltung der Kraftstoffpumpe 1, so daß etwa vorliegende Lecks im Zuge der Kraftstoffversorgung nicht mehr mit Kraftstoff beliefert werden, der zur Ur­ sache eines Fahrzeugbrandes werden kann.In the connecting line between this block 5 on the one hand and the pump relay 4 on the other hand, you can see the contact 6 of a crash sensor, which also does not have a ge, since known trigger contact contains, which generates a contact 6 destructive or opening pulse when crash-related forces occur . Inde pendent of whether the internal combustion engine of the vehicle comes immediately or in the considered case of a crash to a halt continues to run, thus takes place by interrupting the Ver connection between block 5 and pump relay 4 quickly the opening of the contact 3, and thus the switch-off of the fuel pump 1, so that about existing leaks in the course of fuel supply can no longer be supplied with fuel that can become the cause of a vehicle fire.

An dieser Stelle sei eingefügt, daß durch die erfindungsgemäße Sicherheitseinrichtung auch einem Überlaufen der Vergaserschwimmerkammer bei einer Vergaser-Brennkraft­ maschine entgegengewirkt wird.At this point it should be inserted that by the safety device according to the invention also an overflow of the carburetor float chamber with a carburetor internal combustion engine machine is counteracted.

Während in dem bisher beschriebenen Ausführungsbeispiel ein Crashsensor mit elektrischer Betätigung angenommen wurde, zeigt das ebenfalls aus Fig. 1 ersichtliche zweite Aus­ führungsbeispiel eine dadurch gekennzeichnete Sollbruchstelle im unmittelbaren Pumpen­ stromkreis, daß die elektrische Leitung 7 örtlich mit einer trägen Masse 8 versehen ist, die beim Auftreten einer crashbedingten Fahrzeugverzögerung durch ihre Trägheit die Leitung 7 unterbricht. Anstelle der Masse 8 können auch crashbedingte Verformungen von Teilen des Fahrzeugs ausgenutzt werden.While a crash sensor with electrical actuation was assumed in the exemplary embodiment described so far, the second exemplary embodiment also shown in FIG. 1 shows a predetermined breaking point characterized in the direct pumping circuit that the electrical line 7 is locally provided with an inertial mass 8 , which at Occurrence of a crash-related vehicle deceleration due to its inertia, the line 7 interrupts. Instead of the mass 8 , deformations of parts of the vehicle due to crashes can also be used.

Auch das Ausführungsbeispiel nach Fig. 2 sieht eine Sollbruchstelle und die Ausnutzung von Trägheitskräften im Crashfall zum Unwirksammachen der - bei dieser Lösungsvarian­ te nicht abgeschalteten - Kraftstoffpumpe vor. In dem Ausführungsbeispiel nach Fig. 2 ist die Pumpe 10 innerhalb des Kraftstofftanks 11 üblichen und daher nicht zu beschrei­ benden Aufbaus angeordnet. Sie stützt sich über das elastische Teil 12 in der Bodenver­ tiefung 13 des Tanks 11 ab, in den übrigens bei 14 die Kraftstoff-Rücklaufleitung ein­ mündet. Der auch zum Ein- und Ausbau der Pumpe 10 dienende Deckel 15 wird von der Kraftstoff-Vorlaufleitung 16 durchsetzt, die sich in den zu dem Vergaser oder einem an­ deren Kraftstoffzumeßorgan führenden Schlauch 17 fortsetzt. Innerhalb des Tanks 11 ist also die Vorlaufleitung 16 als starres Rohr ausgebildet, so daß sie auch zur Halterung der Pumpe 10 beiträgt.The exemplary embodiment according to FIG. 2 also provides a predetermined breaking point and the use of inertial forces in the event of a crash in order to render the fuel pump ineffective - in the case of this solution variant not switched off. In the embodiment of FIG. 2, the pump 10 is arranged within the fuel tank 11 usual and therefore not descriptive structure. It is supported by the elastic part 12 in the Bodenver recess 13 of the tank 11 , in which incidentally, the fuel return line opens at 14 . The cover 15 , which is also used for installing and removing the pump 10 , is penetrated by the fuel feed line 16 , which continues into the hose 17 leading to the carburetor or to a fuel metering member. Within the tank 11 , the flow line 16 is thus designed as a rigid tube, so that it also contributes to the mounting of the pump 10 .

Bei 18 erkennt man eine Sollbruchstelle in der Vorlaufleitung 16, ausgebildet als umlau­ fende Verringerung der Wandstärke des Rohres. Diese Verringerung ist so bemessen, daß von der Pumpe 10 und dem unteren Teil der Vorlaufleitung 16 im Crashfall ausgeübte Trägheitskräfte - übrigens über einen Winkel von 360° in einer zur Zeichenebene senk­ rechten Ebene - zu einem Durchtrennen der Vorlaufleitung 16 führen. Unabhängig davon, ob die Pumpe 10 weiterläuft oder nicht, wird also ihre Wirkung dadurch unterbunden, daß die Vorlaufleitung 16 unterbrochen wird.At 18 you can see a predetermined breaking point in the flow line 16 , formed as umlau fende reduction in the wall thickness of the tube. This reduction is such that inertia forces exerted by the pump 10 and the lower part of the supply line 16 in the event of a crash - incidentally over an angle of 360 ° in a plane perpendicular to the plane of the drawing - lead to a severing of the supply line 16 . Regardless of whether the pump 10 continues to run or not, its effect is prevented by interrupting the flow line 16 .

Wie auch die Ausführungsbeispiele zeigen, ist mit der Erfindung eine sehr einfach aufge­ baute Sicherheitseinrichtung geschaffen, die im Crashfall unabhängig davon, ob die Brenn­ kraftmaschine weiterläuft oder nicht, das Austreten von Kraftstoff durch Unwirksamma­ chen der Kraftstofförderpumpe verhindert.As the exemplary embodiments also show, the invention is a very simple one built safety device created in the event of a crash regardless of whether the burning engine continues to run or not, the leakage of fuel through ineffective gamma Chen prevented the fuel pump.
