Description

Patentiert im Deutschen Reiche vom 28. Dezember 1928 ab Gegenstand der Erfindung ist eine Sicherheitsvorrichtung ,gegen Diebstahl von Kraftfahrzeugen. Es sind bereits Sicherheitsvorrichtungen gegen Diebstahl von Kraftfahrzeugen bekannt geworden, bei denen in der Brennstoffzuführungsleitung zum Vergaser ein elektromagnetisch gesteuertes Absperrventil eingebaut ist. Bei diesen bekannten Vorrichtungen wird der. auf das Ventil einwirkende Stromkreis durch einen Schlüssel geschlossen. Eine derartige Anordnung besitzt den Nachteil, daß schon beim Einstecken des Schlüssels in die Vorrichtung die Brennstoffzufuhr geöffnet ist, so, daß Brennstoff nachfließen kann. Demgegenüber zeigt die Erfindung den Vorteil, daß Brennstoff erst freigegeben wird, wenn der Öldruckmesser in Tätigkeit tritt, also sobald durch Andrehen des Motors mittels Kurbel oder mittels Anlassers der Öldruckmesser in Tätigkeit tritt. Zu diesem. Zwecke wird erfindungsgemäß der auf das Ventil einwirkende Stromkreis außer durch einen Steckschlüssel noch durch eine im Öldruckmesser vorgesehene Kontaktvorrichtung geschlossen. Dies bietet den Vorteil, daß kein Brennstoff vorzeitig zufließen kann, und den Vorteil der erhöhten Sicherheit gegen Diebstahl.Patented in the German Empire on December 28, 1928 from subject The invention is a security device against theft of motor vehicles. Security devices against theft of motor vehicles are already known become, in which in the fuel supply line to the carburetor an electromagnetic controlled shut-off valve is installed. In these known devices the. The circuit acting on the valve is closed by a key. One Such an arrangement has the disadvantage that already when inserting the key the fuel supply is open in the device, so that fuel continues to flow can. In contrast, the invention has the advantage that fuel is only released is when the oil pressure gauge comes into action, i.e. as soon as the Engine by means of a crank or starter the oil pressure gauge comes into operation. To this. The purpose of the invention is the circuit acting on the valve in addition to a socket wrench, a contact device provided in the oil pressure gauge closed. This has the advantage that no fuel can flow in prematurely, and the advantage of increased security against theft.

Die Erfindung ist in einem Ausführungsbeispiel in den Abbildungen dargestellt, und zwar zeigt Abb. i einen Vertikalschnittdurch das Ventil, und Abb. 2 zeigt eine schematische Darstellung der Anordnung gemäß der Erfindung unter Anwendung eines Steckschlüssels und eines Öldruckmessers.The invention is shown in one embodiment in the figures shown, namely Fig. i shows a vertical section through the valve, and Fig. Figure 2 shows a schematic representation of the arrangement according to the invention in use a socket wrench and an oil pressure gauge.

Das Ventil besteht aus dem Gehäuse i mit der Platte 2, an welcher der zweipolige Elektromagnet befestigt ist, dessen Kern mit den Polschuhen q. und 5 versehen ist. Der Elektromagnet ragt mit seinen Polschuhen in das Innere des Gehäuses i, so daß er also vollständig geschützt ist. In einer Führungsbüchse 8 gleitet der Schaft 13 mit denn Anker 6. Am unteren Ende des Schaftes lagert der Ventilkegel IO mit der eingelassenen Korkplatte II. Die Druckfeder 9,drückt den Ventilkegel IO auf seinen Sitz 12, so,daß eine absolute Abdichtung,des Ventils gewährleistet wird. Die Klemmschrauben 1q. und 15 dienen zur Stromzuführung. 16 ist der Stutzen, der mit dem Brennstoffbehälter in Verbindung steht, und 17 ist der nach dem Vergaser führende Auslaßstutzen. An der Polklernrne 1q. ist die Leitung 18 angeschlossen, die nach der Masse z9 bzw. nach der Erde führt. An der Polklemme 14 ist die Leitung 2o angeschlossen, die gemäß Abb. zunächst nach dem kreisringförmigen Kontakt 25 führt, !der im Öldruckmesser 26 vorgesehen ist. 27 .ist der Zeiger des Öldruckrnessers, von,dessen Drehpunkt die Leitung 28 nach dem Stecker :2r führt. Über den Steckschlüssel führt der Stromkreis weiter nach der Batterie 23. Von da läuft der Draht wieder zur Masse 19.The valve consists of the housing i with the plate 2, to which the two-pole electromagnet is attached, the core of which with the pole pieces q. and 5 is provided. The electromagnet protrudes with its pole pieces into the interior of the housing i, so that it is completely protected. In a guide bushing 8, the shaft 13 slides with the armature 6. At the lower end of the shaft, the valve cone IO rests with the embedded cork plate II. The compression spring 9 presses the valve cone IO onto its seat 12, so that an absolute seal of the valve is guaranteed. The clamping screws 1q. and 15 are used to supply power. 16 is the port that communicates with the fuel tank, and 17 is the outlet port leading to the carburetor. At Polklernrne 1q. the line 18 is connected, which leads to the ground z9 or to the earth. The line 2o is connected to the pole terminal 14 and, as shown in the figure, initially leads to the annular contact 25, which is provided in the oil pressure meter 26. 27. Is the pointer of the oil pressure gauge from whose pivot point the line 28 leads to the connector: 2r. The circuit continues via the socket wrench to the battery 23. From there the wire runs back to ground 19.

Die Wirkungsweise ist folgende: Für gewöhnlich wird das Ventil io von der Feder 9 auf seinen Sitz i2 gedrückt. Wird bei der Ausführungsform gemäß Abb. 2 der Steckschlüssel 22 eingeführt und der Motor in Umdrehung gebracht, so wird der Stromkreis geschlossen und der Elektromagnet 3 erregt, so d'aß das Ventil io von seinem Sitz, entgegen der Wirkung der Feder 9, angehoben wird, unid nunmehr der Brennstoff durch de Leitung 16 über die Leitung 17 nach dem Vergaser gelangen kann. Beim: Stillstand des Motors, sei es mit oder auch ohne Entfernen des Steckschlüssels 22, wird die Brennstoffzufuhr selbsttätig wieder unterbrochen, indem die Feder 9,das Ventil io niederdrückt.The mode of operation is as follows: Usually the valve io is pressed by the spring 9 onto its seat i2. If, in the embodiment according to Fig. 2, the socket wrench 22 is inserted and the motor is set in rotation, the circuit is closed and the electromagnet 3 is excited so that the valve is lifted from its seat against the action of the spring 9 , and the fuel can now pass through the line 16 via the line 17 to the carburetor. When the engine comes to a standstill, be it with or without removing the socket wrench 22, the fuel supply is automatically interrupted again in that the spring 9 depresses the valve io.
