Description

Die Erfindung betrifft eine Vorrichtung zur Sicherung von Anlagen nach dem Oberbegriff des Patenanspruchs 1.The invention relates to a device for securing systems according to the preamble of patent claim 1.

Eine solche Vorrichtung ist aus der Praxis bereits bekannt. In den Vereinigten Staaten von Amerika fahrende Lokomotiven weisen teilweise Notabschalteinrichtungen auf, die per Hand betätigt werden können und rein mechanisch wirken. Solche Notabschalteinrichtungen verfügen beispielsweise über einen Seilzug und ein Kniehebel- oder sonstige Ventile.Such a device is already known from practice. Locomotives operating in the United States sometimes have emergency shutdown devices that can be operated by hand and are purely mechanical. Such Notabschalteinrichtungen have, for example, a cable and a toggle or other valves.

Aus der Patentschrift US 4,492,191 A ist eine Kraftstoffunterbrechungseinrichtung für Kraftstoffeinspritzpumpen für Mehrzylinder-Verbrennungsmotoren bekannt. Kraftstoff wird aus einem Kraftstofftank mittels Einspritzpumpen in Einspritzröhren gepumpt, an deren Ende Einspritzdüsen zum Eispritzen des Kraftstoffes in die Motorzylinder angeordnet sind. In den Einspritzröhren sind Schaltventile angeordnet, die eine Einspritzstellung zur Zuführung von Kraftstoff zu den Einspritzdüsen und eine Rückführstellung zur Rückführung des Kraftstoffs in den Kraftstofftank aufweisen. Die Schaltventile sind pneumatisch über einen Pneumatikzylinder ansteuerbar. Wird der Kolben des Pneumatikzylinders mit Druckluft beaufschlagt, so bringt die Kolbenstange die Schaltventile in Einspritzstellung. Wird die Druckluftbeaufschlagung unterbrochen, so bewegt eine Rückstellfeder Kolben und Kolbenstange zurück, wodurch das Schaltventil in seine Rückführstellung gebracht wird. Der Pneumatikzylinder wird aus einem Drucklufttank mit Druckluft beaufschlagt, wenn ein zwischengeschaltetes, elektrisch betätigbares Steuerventil die Druckluftverbindung freigibt.From the patent US 4,492,191 A For example, a fuel cut device for fuel injection pumps for multi-cylinder internal combustion engines is known. Fuel is pumped from a fuel tank by means of injection pumps in injection tubes, at the end of injection nozzles for ice spraying of the fuel are arranged in the engine cylinders. In the injection tubes switching valves are arranged, which have an injection position for supplying fuel to the injection nozzles and a return position for returning the fuel into the fuel tank. The switching valves can be controlled pneumatically via a pneumatic cylinder. If compressed air is applied to the piston of the pneumatic cylinder, the piston rod brings the switching valves into the injection position. If the pressurization of compressed air is interrupted, then a return spring moves the piston and piston rod back, whereby the switching valve is brought into its return position. The pneumatic cylinder is pressurized with compressed air from a compressed air tank when an interposed, electrically actuated control valve releases the compressed air connection.

Darüber hinaus sind Lokomotiven bekannt, die an ihren beiden Seiten jeweils mit einem Schalter ausgerüstet sind. Der dort angeordnete Schalter löst eine Motorabschaltung aus, die jedoch - insbesondere bei Dieselmotoren - fehleranfällig ist und nicht immer sicher zum Abstellen des Motors führt.In addition, locomotives are known, which are each equipped with a switch on both sides. The switch arranged there triggers an engine shutdown, however - Especially in diesel engines - is prone to error and does not always safely turn off the engine.

Aus der Praxis sind ferner pneumatische Kraftstoffabsperrventile mit elektropneumatischer Vorsteuerung bekannt. Die vorbekannten pneumatischen Notabsperrventile sind jedoch derart, dass diese bei fehlender Druckluft selbsttätig in ihre geöffnete Stellung übergehen. Dies ist zweckmäßig, um über längere Zeiträume abgestellte Lokomotiven, deren Druckluftbehälter keine Druckluft mehr aufweist, wieder aufrüsten zu können. Sind die pneumatischen Notabsperrventile in ihrer geöffneten Stellung, ist der Kraftstofftank jedoch fortwährend mit dem Verbraucher verbunden. Daraus ergibt sich eine Sicherheitslücke im Gesamtsystem.From practice, pneumatic fuel shut-off valves with electro-pneumatic pilot control are also known. However, the previously known pneumatic Notabsperrventile are such that they automatically go in the absence of compressed air in its open position. This is useful to be able to upgrade over longer periods locomotives whose compressed air tank has no more compressed air to be able to upgrade. However, when the pneumatic emergency shut-off valves are in their open position, the fuel tank is continually connected to the consumer. This results in a security gap in the overall system.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs genannten Art zu schaffen, die eine durchgehende und lückenlose Sicherheit bereitstellt.The object of the invention is therefore to provide a device of the type mentioned, which provides a continuous and complete security.

Diese Aufgabe wird im Rahmen der Erfindung gelöst durch eine gattungsgemäße Vorrichtung mit den im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmalen.This object is achieved in the invention by a generic device with the features specified in the characterizing part of claim 1.

Erfindungsgemäß ist das Notabsperrventil zusätzlich elektrisch oder elektromagnetisch betätigbar und über einen Absperrventilstromkreis mit einem Energiespeicher verbindbar. Neben einer pneumatischen Ansteuerung des Notabsperrventils ist im Rahmen der Erfindung darüber hinaus auch eine elektrische Betätigung oder mit anderen Worten eine elektrische Ansteuerung des Notabsperrventils möglich. So weist das Notabsperrventil beispielsweise eine Spule auf, die bei geschlossenem Notabsperrventilstromkreis erregt wird und ein magnetisches Feld erzeugt, das das Notabsperrventil in seine Durchgangsstellung überführt. Demnach muss das Notabsperrventil nicht notwendigerweise pneumatisch betätigt werden. Ist beispielsweise die erfindungsgemäße Vorrichtung Teil einer Lokomotive und ist die Lokomotive nach langen Standzeiten vollständig abgerüstet, weisen deren Druckluftbehälter keine Druckluft mehr auf. Ein Starten der Dieselmotoren wäre dann nicht möglich, da Kraftstofftank und Verbraucher durch das Notabsperrventil voneinander getrennt sind. In diesem Fall stellt der Energiespeicher die notwendige Elektroenergie bereit, so dass das Notabsperrventil mittels dieser elektrischen Notbeschaltung geöffnet werden kann. Als Energiespeicher eignet sich hier beispielsweise eine Batterie, mit anderen Worten ein chemischer Akkumulator oder ein sonstiger Energiespeicher, der zur Erzeugung von Elektroenergie und zur Einspeisung eines Stromes in den Absperrventilstromkreis eingerichtet ist.According to the emergency shutoff valve is additionally electrically or electromagnetically actuated and connected via a shut-off valve circuit with an energy storage. In addition to a pneumatic control of the emergency shut-off valve, an electric actuation or in other words an electrical actuation of the emergency shut-off valve is also possible within the scope of the invention. For example, the emergency shut-off valve has a coil that is energized when the emergency shut-off valve circuit is closed and generates a magnetic field that transfers the emergency shut-off valve to its open position. Thus, the emergency shut-off valve does not necessarily have to be pneumatically operated. For example, if the device according to the invention is part of a locomotive and the locomotive is completely disarmed after a long service life, the compressed air tanks have no More compressed air. Starting the diesel engines would not be possible because the fuel tank and consumers are separated from each other by the emergency shut-off valve. In this case, the energy storage provides the necessary electrical energy, so that the Notabsperrventil can be opened by means of this electrical emergency circuit. As energy storage is here, for example, a battery, in other words, a chemical accumulator or other energy storage, which is set up for the generation of electrical energy and for feeding a current in the shut-off valve circuit.

Der Verbraucher ist beispielsweise eine Gasturbine, ein Verbrennungsmotor, insbesondere Dieselmotor, oder eine sonstige Verbrennungsmaschine.The consumer is, for example, a gas turbine, an internal combustion engine, in particular a diesel engine, or another internal combustion engine.

Vorteilhafterweise ist das Notabsperrventil über eine Druckluftleitung mit einem Druckluftbehälter verbindbar. Ist der Druckluftbehälter somit mit Druckluft befüllt, kann das Notabsperrventil mit Druckluft beaufschlagt werden, wobei es in seine Durchgangsstellung überführt oder gehalten wird. In dieser Stellung ist der Verbraucher mit dem Kraftstofftank verbunden, so dass durch die Verbrennung des in dem Kraftstofftank angeordneten Kraftstoffs im Verbraucher eine Antriebsbewegung, beispielsweise für eine Lokomotive, erzeugbar ist.Advantageously, the emergency shut-off valve can be connected via a compressed air line to a compressed air tank. If the compressed air tank is thus filled with compressed air, the emergency shut-off valve can be acted upon with compressed air, wherein it is transferred or held in its passage position. In this position, the consumer is connected to the fuel tank, so that by the combustion of the disposed in the fuel tank fuel in the consumer a drive movement, for example, for a locomotive, can be generated.

Vorteilhafterweise ist in dem Absperrventilstromkreis ein Druckluftschalter angeordnet, der über eine Druckluftleitung mit einem Druckbehälter verbunden ist, wobei der Druckluftschalter bei einer Beaufschlagung mit Druckluft den Absperrventilstromkreis unterbricht. Gemäß dieser vorteilhaften Weiterentwicklung ist vorgesehen, die elektrische oder elektromagnetische Betätigung des Notabsperrventils dann wieder auszusetzen, wenn ausreichend Druckluft zur Verfügung steht, um das Notabsperrventil allein pneumatisch betätigen zu können und dieses somit in seiner geöffneten Stellung zu halten. Das Abschalten der elektromagnetischen Betätigung erfolgt im Rahmen dieser Weiterentwicklung pneumatisch, so dass die besagte Abschaltung erst dann durchgeführt werden kann, wenn ausreichend Druckluft sowohl für die Betätigung des Notabsperrventils als auch zum Abschalten des Absperrventilstromkreises zur Verfügung steht. Im Betrieb wird die Vorrichtung somit allein pneumatisch betätigt. Durch die pneumatische Betätigung wird eine zusätzliche Wärmebelastung mit einer unerwünschten Temperaturerhöhung im Gefolge verhindert. Darüber hinaus sind allein pneumatisch betätigte Ventile in der Regel gegenüber Temperaturschwankungen und hohen Temperaturen unempfindlicher als Ventile, die elektrisch oder elektromagnetisch angesteuert werden. Bei der elektrischen oder elektrodynamischen Betätigung handelt es sich im Rahmen der Erfindung lediglich um eine elektrische Notbetätigung (Hilfsbetätigung).Advantageously, a compressed air switch is arranged in the shut-off valve circuit, which is connected via a compressed air line to a pressure vessel, wherein the compressed air switch interrupts the shut-off valve circuit when subjected to compressed air. According to this advantageous further development, it is provided to suspend the electrical or electromagnetic actuation of the emergency shut-off valve again when sufficient compressed air is available to be able to pneumatically actuate the emergency shut-off valve alone and thus to keep it in its open position. The switching off of the electromagnetic actuation takes place in the frame this advancement pneumatically, so that the said shutdown can only be carried out when sufficient compressed air for both the operation of Notabsperrventils as well as for switching off the shut-off valve circuit is available. In operation, the device is thus pneumatically operated alone. By the pneumatic actuation an additional heat load is prevented with an undesirable increase in temperature in the wake. In addition, only pneumatically actuated valves are usually insensitive to temperature fluctuations and high temperatures than valves that are electrically or electromagnetically controlled. In the electrical or electrodynamic actuation is within the scope of the invention, only an electric emergency operation (auxiliary operation).

Gemäß einer bevorzugten Ausgestaltung sind Notabsperrventil und Druckluftschalter über einen gemeinsamen Druckluftleitungsabschnitt mit einem Druckluftbehälter verbunden, wobei in dem gemeinsamen Druckluftleitungsabschnitt ein Vorsteuerventil angeordnet ist. Das Vorsteuerventil kann die Verbindung zwischen Druckluftbehälter und Notabsperrventil beziehungsweise Druckluftschalter ermöglichen oder aber unterbrechen. Unterbricht das Vorsteuerventil die besagte Verbindung, ist weder eine pneumatische Betätigung des Notabsperrventils noch eine pneumatische Betätigung des Druckluftschalters möglich. Dies hat zur Folge, dass der Absperrventilstromkreis nicht unterbrochen ist und das Notabsperrventil somit elektrisch oder elektromagnetisch betätigt werden kann. Bei fehlender pneumatischer und elektrischer oder elektromagnetischer Betätigung wird das Notabsperrventil im Rahmen der Erfindung in seine Sperrstellung überführt, so dass der Kraftstofftank vom Verbraucher getrennt ist.According to a preferred embodiment emergency shut-off valve and compressed air switch are connected via a common compressed air line section with a compressed air tank, wherein in the common compressed air line section, a pilot valve is arranged. The pilot valve can allow or interrupt the connection between the compressed air tank and Notabsperrventil or compressed air switch. If the pilot valve interrupts said connection, neither pneumatic actuation of the emergency shut-off valve nor pneumatic actuation of the pneumatic switch is possible. This has the consequence that the shut-off valve circuit is not interrupted and the emergency shut-off valve can thus be operated electrically or electromagnetically. In the absence of pneumatic and electrical or electromagnetic actuation the emergency shut-off valve is transferred in the context of the invention in its blocking position, so that the fuel tank is disconnected from the consumer.

Gemäß einer bevorzugten Ausgestaltung ist das Vorsteuerventil elektrisch oder elektromagnetisch betätigbar. Hierzu ist das Vorsteuerventil beispielsweise über ein Vorsteuerventilstromkreis mit einem Energiespeicher verbunden, so dass eine elektrische oder elektromagnetische Betätigung des Vorsteuerventils ermöglicht ist.According to a preferred embodiment, the pilot valve is electrically or electromagnetically actuated. For this purpose, the pilot valve is connected, for example via a pilot valve circuit with an energy storage, so that an electrical or electromagnetic actuation of the pilot valve is possible.

Vorteilhafterweise sind im Rahmen der Erfindung Startschalter zum Schließen und Unterbrechen des Vorsteuerventilstromkreises und/oder eines Absperrventilstromkreises vorgesehen. Mit Hilfe des Startschalters kann beispielsweise der Vorsteuerventilstromkreis geschlossen werden, so dass die Spule des Vorsteuerventils erregt wird und dieses in seine geöffnete Stellung überführt. In der geöffneten Stellung sind Druckluftschalter und das pneumatisch betätigbare Notabsperrventil mit dem mit Druckluft befüllten Druckbehälter verbunden, so dass das Notabsperrventil pneumatisch betätigt und der Absperrventilstromkreis unterbrochen werden kann.Advantageously, starter switches for closing and interrupting the pilot valve circuit and / or a shut-off valve circuit are provided in the context of the invention. With the help of the start switch, for example, the pilot valve circuit can be closed, so that the coil of the pilot valve is energized and this transferred to its open position. In the open position, the pneumatic switch and the pneumatically actuated emergency shut-off valve are connected to the pressure vessel filled with compressed air, so that the emergency shut-off valve can be pneumatically actuated and the shut-off valve circuit can be interrupted.

Im Rahmen der Erfindung kann lediglich ein Startschalter vorgesehen sein. Abweichend hiervon sind beispielsweise zwei Startschalter vorgesehen, die in je einem der beiden Führerstände einer Lokomotive angeordnet sind.In the context of the invention, only a start switch can be provided. Notwithstanding this, for example, two start switch are provided, which are arranged in each one of the two driver's cabs of a locomotive.

Neben Startschaltern ist es erfindungsgemäß auch möglich, Notausschalter vorzusehen, die beispielsweise im Seitenbereich einer Lokomotive oder in deren Maschinenraum angeordnet sind, in der die Vorrichtung gemäß der vorliegenden Erfindung verbaut ist. Die Notausschalter dienen zum Unterbrechen des Vorsteuerventilstromkreises und/oder des Absperrventilstromkreises. Auf diese Weise wird das Vorsteuerventil in seine Sperrstellung überführt, so dass eine pneumatische Betätigung des Notabsperrventils nicht mehr möglich ist. Dieses wird daher bei fehlender elektrischer oder elektromagnetischer Betätigung in seine Sperrstellung überführt. Kraftstofftank und Verbraucher sind dann voneinander getrennt. Eine elektrische oder elektromagnetische Betätigung des Notabsperrventils ist aufgrund der Trennung des Absperrventilstromkreises nach Betätigung der Notausschalter nicht möglich.In addition to start switches, it is also possible according to the invention to provide emergency stop switches, which are arranged, for example, in the side area of a locomotive or in its engine room, in which the device according to the present invention is installed. The emergency stop switches are used to interrupt the pilot valve circuit and / or the shut-off valve circuit. In this way, the pilot valve is transferred to its locked position, so that a pneumatic actuation of Notabsperrventils is no longer possible. This is therefore transferred in the absence of electrical or electromagnetic actuation in its locked position. Fuel tank and consumers are then separated. An electrical or electromagnetic actuation of Notabsperrventils is not possible due to the separation of the shut-off valve circuit after pressing the emergency stop.

Die Erfindung betrifft ferner ein Schienenfahrzeug mit einer Vorrichtung gemäß der weiter oben ausgeführten Erfindung.The invention further relates to a rail vehicle with a device according to the invention outlined above.

Weitere zweckmäßige Ausgestaltungen und Vorteile der Erfindung sind Gegenstand der nachfolgenden Beschreibung eines Ausführungsbeispiels der Erfindung unter Bezug auf die Figur der Zeichnung, wobei die

Figur
ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung zeigt.
Further expedient refinements and advantages of the invention are the subject of the following description of a Embodiment of the invention with reference to the figure of the drawing, wherein the
figure
an embodiment of the device according to the invention shows.

Die einzige Figur der Zeichnung zeigt ein Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung 1, die einen Kraftstofftank 2 sowie einen Dieselmotor 3 als Verbraucher aufweist. Der Kraftstofftank 2 ist mit einem Kraftstoff 4 befüllt, wobei der Befüllungsgrad des Kraftstofftanks 2 durch einen Schwimmer 5 erfasst und durch nicht figürlich dargestellte Signalübertragungsmittel im Führerstand einer Lokomotive angezeigt wird.The sole FIGURE of the drawing shows an embodiment of a device 1 according to the invention, which has a fuel tank 2 and a diesel engine 3 as a consumer. The fuel tank 2 is filled with a fuel 4, wherein the degree of filling of the fuel tank 2 is detected by a float 5 and displayed by signal transmission means not shown in the cab of a locomotive.

Der Dieselmotor 3 ist über eine Kraftstoffleitung 6 mit dem Kraftstofftank 2 verbunden. In der Kraftstoffleitung 6 ist ein Notabsperrventil 7 angeordnet. Bei dem angezeigten Notabsperrventil 7 handelt es sich um ein Zwei-Wege-Ventil mit Sperr-Ruhestellung. Mit anderen Worten geht das Notabsperrventil 7 bei fehlender Betätigung entweder in seine in der Figur gezeigte Sperrstellung über oder verbleibt in dieser. Befindet sich das Notabsperrventil 7 in seiner gezeigten Sperrstellung, ist die Verbindung zwischen Dieselmotor 3 und Kraftstofftank 2 unterbrochen. Die an die Vorrichtung 1 gestellten Sicherheitsanforderungen sind somit im Rahmen der Erfindung erfüllt. Bei dem figürlich dargestellten Notabsperrventil 7 handelt es sich um ein pneumatisch betätigbares Notabsperrventil 7, wobei gleichzeitig eine elektrische oder elektromagnetische Notbetätigung möglich ist, auf die später noch genauer eingegangen werden wird.The diesel engine 3 is connected via a fuel line 6 to the fuel tank 2. In the fuel line 6 an emergency shut-off valve 7 is arranged. The Notabsperrventil shown 7 is a two-way valve with lock-rest position. In other words, the emergency shut-off valve 7 either overflows or remains in its blocking position shown in the figure in the absence of actuation. If the emergency shut-off valve 7 is in its blocking position as shown, the connection between the diesel engine 3 and the fuel tank 2 is interrupted. The security requirements imposed on the device 1 are thus fulfilled within the scope of the invention. In the emergency shut-off valve 7 shown in the figures is a pneumatically actuated Notabsperrventil 7, wherein at the same time an electric or electromagnetic emergency operation is possible, which will be discussed in more detail later.

Die Vorrichtung 1 umfasst ferner einen Druckluftbehälter 8, der mit einem pneumatischen Steuerungsanschluss 9 des Notabsperrventils 7 sowie mit einem Druckluftschalter 10 verbunden werden kann. Der pneumatische Steuerungsanschluss 9 ist hierzu über eine erste Druckluftverbindung 11 und der Druckluftschalter über eine zweite Druckluftverbindung 12 mit dem Druckluftbehälter 8 verbunden. Dabei ist ein beiden Verbindungen gemeinsamer Druckluftleitungsabschnitt 13 ausgebildet, in dem ein Vorsteuerventil 14 angeordnet ist. Das Vorsteuerventil 14 ist elektrisch und in diesem Fall elektromagnetisch betätigbar, wobei zur elektromagnetischen Betätigung beispielsweise eine Spule 15 des Vorsteuerventils 14 erregt werden muss. Für seine elektrische oder elektromagnetische Betätigung weist das Notabsperrventil 7 ebenfalls eine Spule 15 auf. Die Spule 15 des Vorsteuerventils 14 ist über einen Vorsteuerventilstromkreis 16 mit einer Batterie 17 als Energiespeicher verbunden. Die Spule 15 des Notabsperrventils 7 ist über einen Absperrventilstromkreis 18 mit der gleichen Batterie 17 verbunden. Sowohl im Absperrventilstromkreis 18 als auch im Vorsteuerventilstromkreis 16 ist ein Startschalter 19 geschaltet, der im Führerstand einer Lokomotive angeordnet ist. Ein zweiter, figürlich nicht dargestellter Startschalter ist dem Startschalter 19 parallel geschaltet und im anderen Führerstand der Lokomotive angeordnet. Darüber hinaus sind beispielsweise sechs Notausschalter 20 vorgesehen, die, wie die Startschalter 19, zum Unterbrechen und Schließen des Absperrventilstromkreises 18 und des Vorsteuerventilstromkreises 16 dienen. Zwei Notausschalter sind in den Führerständen, zwei weitere außen an der Seitenwand und schließlich zwei im Maschinenraum angeordnet. Um mit den gleichen Schaltern 19, 20 beide Stromkreise 16 und 18 gleichzeitig unterbrechen zu können, weisen Absperrventilstromkreis 18 und Vorsteuerventilstromkreis 16 einen gemeinsamen Zweig 21 auf, in dem die besagten Schalter 18 und 20 angeordnet sind.The device 1 further comprises a compressed air tank 8 which can be connected to a pneumatic control connection 9 of the emergency shut-off valve 7 as well as to a compressed-air switch 10. The pneumatic control connection 9 is for this purpose via a first compressed air connection 11 and the compressed air switch via a second compressed air connection 12 with the Compressed air tank 8 connected. In this case, a joint common compressed air line section 13 is formed in which a pilot valve 14 is arranged. The pilot valve 14 is electrically and in this case electromagnetically actuated, wherein for electromagnetic actuation, for example, a coil 15 of the pilot valve 14 must be energized. For its electrical or electromagnetic actuation, the emergency shut-off valve 7 also has a coil 15. The coil 15 of the pilot valve 14 is connected via a pilot valve circuit 16 to a battery 17 as an energy store. The coil 15 of Notabsperrventils 7 is connected via a shut-off valve circuit 18 with the same battery 17. Both in the shut-off valve circuit 18 and in the pilot valve circuit 16, a start switch 19 is connected, which is arranged in the cab of a locomotive. A second, figuratively not shown start switch is connected in parallel to the start switch 19 and arranged in the other cab of the locomotive. In addition, six emergency stop switches 20 are provided, for example, which, like the start switch 19, serve to interrupt and close the shut-off valve circuit 18 and the pilot valve circuit 16. Two emergency stop switches are located in the driver's cabs, two more on the outside of the sidewall and finally two in the engine room. In order to be able to interrupt both circuits 16 and 18 simultaneously with the same switches 19, 20, shut-off valve circuit 18 and pilot valve circuit 16 have a common branch 21, in which said switches 18 and 20 are arranged.

Der Druckluftbehälter 8 kann bei laufendem Dieselmotor 3 über einen figürlich nicht dargestellten Kompressor des Schienenfahrzeugs mit Druckluft befüllt werden. Dabei wird der Kompressor im Betrieb vom Dieselmotor 3 angetrieben.The compressed air tank 8 can be filled with running diesel engine 3 via a compressor, not shown figuratively, of the rail vehicle with compressed air. The compressor is driven by the diesel engine 3 during operation.

Zum Abrüsten des Schienenfahrzeugs wird der Dieselmotor 3 abgeschaltet. Anschließend wird das Vorsteuerventil 14 durch Betätigung eines Startschalters 19 im Führerstand in seine in der Figur gezeigte Sperrstellung überführt. Somit entfällt die pneumatische Betätigung des Notabsperrventils 7. Da durch Öffnen des Absperrventilstromkreises 18 und des Vorsteuerventilstromkreises 16 mit Hilfe der Startschalter 19 auch eine elektromagnetische Betätigung des Notabsperrventils 7 nicht mehr möglich ist, wird dieses selbsttätig beispielsweise durch eine in der Figur nicht gezeigte Feder in seine Sperrstellung überführt, so dass der Dieselmotor 3 vom Kraftstofftank 2, wie vorgeschrieben, getrennt ist. Die Sperrstellung ist daher gleichzeitig die Ruhestellung des Notabsperrventils 7.To disassemble the rail vehicle, the diesel engine 3 is turned off. Subsequently, the pilot valve 14 is transferred by pressing a start switch 19 in the cab in its blocking position shown in the figure. Thus omitted Since the opening of the shut-off valve circuit 18 and the pilot valve circuit 16 by means of the start switch 19 and an electromagnetic actuation of Notabsperrventils 7 is no longer possible, this is automatically transferred, for example by a spring, not shown in the figure in its locked position so that the diesel engine 3 is disconnected from the fuel tank 2 as prescribed. The blocking position is therefore at the same time the rest position of Notabsperrventils. 7

Zum Unterbrechen des Absperrventilstromkreises 18 wirkt der Druckluftschalter 10 mit einem Schalter 22 zusammen, der im Absperrventilstromkreis 18 angeordnet ist. Wird der Druckluftschalter 10 mit Druckluft beaufschlagt, öffnet der Druckluftschalter 10 den Schalter 22. Dies sorgt für eine Unterbrechung des Absperrventilstromkreises 18 und somit für eine Entregung der Spule 15 des Notabsperrventils 7. Eine Erwärmung der Spule 15 und des Notabsperrventils 7 durch die Spule 15 und darüber hinaus ein unerwünschter Energieverbrauch können auf diese Weise vermieden werden.To interrupt the shut-off valve circuit 18, the compressed air switch 10 cooperates with a switch 22 which is arranged in the shut-off valve circuit 18. If the compressed air switch 10 is acted upon with compressed air, the compressed air switch 10 opens the switch 22. This provides for an interruption of the shut-off valve circuit 18 and thus for de-energizing the coil 15 of Notabsperrventils 7. Heating the coil 15 and the Notabsperrventils 7 through the coil 15 and In addition, an undesirable energy consumption can be avoided in this way.

Zum Starten der Lokomotive wird der Startschalter 19 in einem der Füherstände betätigt. Somit werden sowohl Vorsteuerventilstromkreis 16 als auch Absperrventilstromkreis 18 geschlossen. Die Batterie 17 erregt die Spule 15 des Vorsteuerventils 14, so dass dieses in seine Durchgangsstellung überführt wird. Liegt im Druckluftbehälter 8 Druckluft vor, wird der Druckluftschalter 10 betätigt, wodurch der Absperrventilstromkreis 18 unterbrochen wird. Das Notabsperrventil 7 wird somit allein pneumatisch in seine Durchlassstellung überführt. Nach längeren Standzeiten der Lokomotive kann sämtliche Druckluft aus dem Druckluftbehälter 8 entwichen sein. Somit liegt im Sinne der Erfindung keine Druckluft vor. Das Notabsperrventil 7 kann daher nicht pneumatisch betätigt werden. Im Rahmen der Erfindung kommt es jedoch in diesem Falle nicht zur Öffnung des Absperrventilstromkreises 18 durch den Druckluftschalter 10 beziehungsweise den Schalter 22. Mit anderen Worten bleibt die Spule 15 des Notabsperrventils 7 mit der Batterie 17 verbunden und wird daher erregt. Es kommt zur elektromagnetischen Betätigung des Notabsperrventils 7, das dadurch in seine Durchgangsstellung überführt wird. Nun kann der Dieselmotor 3 gestartet werden, der wiederum den Kompressor zur Bereitstellung von Druckluft im Druckluftbehälter 8 antreibt. Ist der Druckluftbehälter 8 ausreichend mit Druckluft befüllt, kommt es zur pneumatischen Betätigung von Druckluftschalter 10 und Notabsperrventil 7, wobei die Verbindung zwischen der Spule 15 des Notabsperrventils 7 und der Batterie 17 durch Öffnen des Schalters 22 unterbrochen wird. Nunmehr wird das Notabsperrventil 7 allein pneumatisch und somit nahezu verlustfrei betätigt.To start the locomotive of the start switch 19 is operated in one of the fiefs. Thus, both pilot valve circuit 16 and shut-off valve circuit 18 are closed. The battery 17 energizes the coil 15 of the pilot valve 14, so that this is transferred to its passage position. If compressed air is present in the compressed air tank 8, the compressed-air switch 10 is actuated, as a result of which the shut-off valve circuit 18 is interrupted. The emergency shut-off valve 7 is thus transferred pneumatically alone into its passage position. After a long service life of the locomotive all compressed air can escape from the compressed air tank 8. Thus, there is no compressed air within the meaning of the invention. The emergency shut-off valve 7 can therefore not be operated pneumatically. In the context of the invention, however, it is not in this case to open the shut-off valve circuit 18 through the air pressure switch 10 and the switch 22. With others In words, the coil 15 of Notabsperrventils 7 is connected to the battery 17 and is therefore energized. It comes to the electromagnetic actuation of Notabsperrventils 7, which is thereby transferred to its passage position. Now, the diesel engine 3 can be started, which in turn drives the compressor to provide compressed air in the compressed air tank 8. If the compressed air tank 8 sufficiently filled with compressed air, it comes to the pneumatic actuation of compressed air switch 10 and Notabsperrventil 7, wherein the connection between the coil 15 of Notabsperrventils 7 and the battery 17 is interrupted by opening the switch 22. Now the emergency shut-off valve 7 is actuated solely pneumatically and thus almost without loss.
