Description

Die Erfindung betrifft eine Vorrichtung zum Speichern von Druckgas, beispielsweise von Wasserstoff oder Erdgas. Bevorzugter Anwendungsbereich der Vorrichtung zum Speichern von Druckgas sind mobile Anwendungen, insbesondere Fahrzeuge, die mit Brennstoffzellen oder einem Gasmotor betrieben werden.The invention relates to a device for storing compressed gas, for example hydrogen or natural gas. The preferred area of application of the device for storing compressed gas is mobile applications, in particular vehicles that are powered by fuel cells or a gas engine.

Die Erfindung betrifft daher ferner ein Fahrzeug mit einer erfindungsgemäßen Vorrichtung zum Speichern von Druckgas.The invention therefore further relates to a vehicle with a device according to the invention for storing compressed gas.

Stand der TechnikState of the art

In mobilen Anwendungen werden Druckgase in der Regel in Druckgasbehältern bevorratet, die eine Flaschenform aufweisen. In der Regel werden mehrere flaschenförmige Druckgasbehälter zu einem Speicher zusammengefasst und in einem Unterboden-Bereich eines Fahrzeugs angeordnet. Aus Sicherheitsgründen muss zu jedem Zeitpunkt die Dichtheit der einzelnen Druckgasbehälter sowie des gesamten Speichers gewährleistet sein. Zum sicheren Verschließen der einzelnen Druckgasbehälter werden Magnetventile eingesetzt, die in stromlosem Zustand geschlossen sind, so dass ein Gasaustritt selbst im Fehlerfall sicher vermieden wird. In Abhängigkeit von der Anzahl der Druckgasbehälter eines Speichers kann sich somit die Anzahl der Ventile schnell erhöhen.In mobile applications, compressed gases are usually stored in compressed gas containers that are bottle-shaped. Usually, several bottle-shaped compressed gas containers are combined to form a storage unit and arranged in the underbody area of a vehicle. For safety reasons, the tightness of the individual compressed gas containers and the entire storage unit must be guaranteed at all times. Solenoid valves are used to securely close the individual compressed gas containers. These are closed when the power is off, so that gas leakage is reliably prevented even in the event of a fault. Depending on the number of compressed gas containers in a storage unit, the number of valves can therefore quickly increase.

Aus der Offenlegungsschrift DE 10 2017 004 451 A1 ist eine Speichereinrichtung für Druckgas mit mehreren Druckgasbehältern bekannt, die jeweils über ein Tankventil und ein Leitungselement an ein gemeinsames Sammelvolumen angeschlossen sind. Das Sammelvolumen, das auch als "Rail" bezeichnet werden kann, reduziert den Verrohrungsaufwand. Zudem ist das Sammelvolumen dahingehend erweitert, dass Ventileinrichtungen, die bisher in der Gaszuleitung oder der Gasableitung vorhanden waren, in das Sammelvolumen integriert sind. Damit reduziert sich die Anzahl der Schnittstellen, was hinsichtlich der Dichtheitsproblematik von Vorteil ist. Die integrierten Ventileinrichtungen sind vorzugsweise ein Rückschlagventil im Bereich einer Gaszuleitung und ein Absperrventil im Bereich einer Gasableitung. Da das Druckniveau im Sammelvolumen dem Nenndruck der Druckgasbehälter entspricht, kann über die in das Sammelvolumen integrierten Ventileinrichtungen die Abdichtung gegenüber den umgebenden Leitungen vorgenommen werden. Die Tankventile, über welche die Druckgasbehälter an das Sammelvolumen angeschlossen sind, verfügen jeweils über eine Betankungs- und Entnahmefunktion.From the disclosure document EN 10 2017 004 451 A1 A storage device for compressed gas with several compressed gas containers is known, each of which is connected to a common collection volume via a tank valve and a line element. The collection volume, which can also be referred to as a "rail", reduces the amount of piping required. In addition, the collection volume has been expanded in such a way that valve devices that were previously present in the gas supply line or the gas discharge line are integrated into the collection volume. This reduces the number of interfaces, which is an advantage in terms of the leak-tightness problem. The integrated valve devices are preferably a check valve in the area of a gas supply line and a shut-off valve in the area of a gas discharge line. Since the pressure level in the collection volume corresponds to the nominal pressure of the compressed gas containers, the valve devices integrated into the collection volume can be used to seal off the surrounding lines. The tank valves, via which the compressed gas containers are connected to the collection volume, each have a refueling and removal function.

Darüber hinaus sind Druckgas-Speichersysteme für mobile Anwendungen bekannt, bei denen das Tankventil zum Befüllen des Speichers mit Druckgas in den Tankanschluss des Fahrzeugs integriert ist, das heißt in den Bereich, in den beim Tanken an der Gastankstelle die Zapfpistole eingesetzt wird. Auf Tankventile in den einzelnen Druckgasbehältern kann dann verzichtet werden. Da diese jedoch in der Regel zugleich eine Absperr- und damit Sicherungsfunktion besitzen, sinkt - insbesondere bei einem Unfall - die Sicherheit des Systems.In addition, compressed gas storage systems for mobile applications are known in which the tank valve for filling the tank with compressed gas is integrated into the tank connection of the vehicle, i.e. in the area where the fuel nozzle is inserted when refueling at the gas station. Tank valves in the individual compressed gas containers can then be dispensed with. However, since these usually also have a shut-off and thus safety function, the safety of the system is reduced - especially in the event of an accident.

Die vorliegende Erfindung ist mit der Aufgabe befasst, eine Vorrichtung zum Speichern von Druckgas anzugeben, die einerseits einen vereinfachten Aufbau aufweist, andererseits hohen Sicherheitsanforderungen genügt.The present invention is concerned with the object of providing a device for storing compressed gas which, on the one hand, has a simplified structure and, on the other hand, meets high safety requirements.

Zur Lösung der Aufgabe wird die Vorrichtung mit den Merkmalen des Anspruchs 1 vorgeschlagen. Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen. Ferner wird ein Fahrzeug mit einer erfindungsgemäßen Vorrichtung angegeben.To achieve the object, the device with the features of claim 1 is proposed. Advantageous further developments of the invention can be found in the subclaims. Furthermore, a vehicle with a device according to the invention is specified.

Offenbarung der ErfindungDisclosure of the invention

Die zum Speichern von Druckgas, beispielsweise Wasserstoff oder Erdgas, vorgeschlagene Vorrichtung weist eine Speicherleitung auf, an die mehrere Druckgasbehälter anschließbar sind. In einen stirnseitigen Endabschnitt der Speicherleitung ist dabei ein Tankventil mit einem Ventilgehäuse und einem im Ventilgehäuse aufgenommenen Filter zum Schutz des Tankventils integriert. Das Ventilgehäuse bildet einen Druckgas-Anschluss aus, über den die Speicherleitung mit Druckgas befüllbar ist.The device proposed for storing compressed gas, for example hydrogen or natural gas, has a storage line to which several compressed gas containers can be connected. In one end section of the storage line, a tank valve with a valve housing and a filter housed in the valve housing to protect the tank valve. The valve housing forms a compressed gas connection through which the storage line can be filled with compressed gas.

Bei der vorgeschlagenen Vorrichtung ist demnach nur ein Tankventil vorgesehen, das in die Speicherleitung integriert ist, so dass diese über das Tankventil mit Druckgas befüllbar ist. Zugleich können über das eine Tankventil auch die an die Speicherleitung angeschlossenen Druckgasbehälter mit Druckgas befüllt werden.The proposed device therefore only provides one tank valve, which is integrated into the storage line so that it can be filled with compressed gas via the tank valve. At the same time, the compressed gas containers connected to the storage line can also be filled with compressed gas via the one tank valve.

Das in die Speicherleitung integrierte Tankventil ermöglicht somit eine Reduzierung der Anzahl der Ventile. Zugleich werden hohe Sicherheitsanforderungen erfüllt, da über das Tankventil eine Absperr- und damit Sicherheitsfunktion in unmittelbarer Nähe zu den Druckgasbehältern gewährleistet ist. Dadurch, dass in das Tankventil zugleich ein Filter integriert ist, wird da Tankventil vor schädlichem Partikeleintrag geschützt, so dass eine hohe Funktionssicherheit gegeben ist. Dadurch, dass das Ventilgehäuse des Tankventils zugleich einen Druckgas-Anschluss ausbildet, stellt das Tankventil die Schnittstelle zu einer Druckgas-Tankleitung dar, über welche die Speicherleitung mit einem Tankanschluss verbindbar ist.The tank valve integrated into the storage line thus enables the number of valves to be reduced. At the same time, high safety requirements are met, as the tank valve ensures a shut-off and thus safety function in the immediate vicinity of the compressed gas containers. Because a filter is also integrated into the tank valve, the tank valve is protected from harmful particle ingress, thus ensuring a high level of functional reliability. Because the valve housing of the tank valve also forms a compressed gas connection, the tank valve represents the interface to a compressed gas tank line, via which the storage line can be connected to a tank connection.

Die Ausbildung des Druckgas-Anschlusses über das Ventilgehäuse des Tankventils erfordert eine Abdichtung zwischen dem Ventilgehäuse und der Speicherleitung, damit kein Druckgas aus der Speicherleitung entweichen kann. Bevorzugt ist daher zwischen dem Ventilgehäuse des Tankventils und der Speicherleitung mindestens ein Dichtelement angeordnet. Das Dichtelement kann beispielsweise ein O-Ring sein, der das Ventilgehäuse des Tankventils umgibt.The formation of the compressed gas connection via the valve housing of the tank valve requires a seal between the valve housing and the storage line so that no compressed gas can escape from the storage line. Preferably, therefore, at least one sealing element is arranged between the valve housing of the tank valve and the storage line. The sealing element can, for example, be an O-ring that surrounds the valve housing of the tank valve.

Alternativ oder ergänzend wird vorgeschlagen, dass die Speicherleitung einen flachen oder konisch geformten Dichtsitz für das Ventilgehäuse ausbildet und das Ventilgehäuse eine mit dem Dichtsitz zusammenwirkende Dichtkontur aufweist, die als Beißkante ausgeführt oder ballig oder konisch geformt ist. Dichtsitz und Dichtkontur wirken dann dichtend zusammen, so dass kein Druckgas aus der Speicherleitung entweichen kann.Alternatively or additionally, it is proposed that the storage line forms a flat or conical sealing seat for the valve housing and that the valve housing has a sealing contour that interacts with the sealing seat and is designed as a biting edge or is spherical or conical in shape. The sealing seat and sealing contour then work together to seal so that no compressed gas can escape from the storage line.

Des Weiteren wird vorgeschlagen, dass im Ventilgehäuse ein hin und her beweglicher Ventilkolben aufgenommen ist, der in Richtung eines Ventilsitzes von der Federkraft einer Feder beaufschlagt ist. Über den federbelasteten Ventilkolben wird die Absperrfunktion des Tankventils realisiert. Die Federkraft der Feder ist derart bemessen, dass das Tankventil über den beim Befüllen der Speicherleitung mit Druckgas anliegenden Gasdruck entgegen der Federkraft geöffnet werden kann.Furthermore, it is proposed that a valve piston which can be moved back and forth is accommodated in the valve housing and which is pushed in the direction of a valve seat by the spring force a spring. The shut-off function of the tank valve is implemented via the spring-loaded valve piston. The spring force of the spring is such that the tank valve can be opened against the spring force via the gas pressure present when the storage line is filled with compressed gas.

Der Ventilkolben des Tankventils kann eine mit dem Ventilsitz zusammenwirkende Dichtfläche aufweisen oder mit einem separaten Ventilschließelement zusammenwirken. Diese kann beispielsweise als Kugel ausgeführt sein. Die Kugel zentriert sich selbst in Bezug auf den Ventilsitz, so dass eine hohe Dichtheit erzielt wird.The valve piston of the tank valve can have a sealing surface that interacts with the valve seat or can interact with a separate valve closing element. This can be designed as a ball, for example. The ball centers itself in relation to the valve seat, so that a high level of tightness is achieved.

Bevorzugt weist der Ventilkolben des Tankventils außenumfangseitig mindestens einen Anschliff und/oder eine Längsnut zur Ausbildung eines Druckgas-Strömungspfads auf. Außerhalb des Anschliffs bzw. der Längsnut kann dann der Ventilkolben im Ventilgehäuse geführt sein.The valve piston of the tank valve preferably has at least one bevel and/or a longitudinal groove on the outer circumference to form a compressed gas flow path. The valve piston can then be guided in the valve housing outside the bevel or the longitudinal groove.

Ferner bevorzugt ist der Ventilkolben als Stufenkolben ausgeführt, das heißt, dass der Ventilkolben mindestens eine Stufe ausbildet. Der als Stufenkolben ausgeführte Ventilkolben wirkt dabei mit einem Absatz des Ventilgehäuses einen Anschlag ausbildend zusammen. Die Stufe ist hierzu an dem Ende des Ventilkolbens ausgeführt, dass dem Ventilsitz abgewandt ist. Zur Ausbildung des Absatzes ist vorzugsweise das Ventilgehäuse mehrteilig ausgeführt. Die mehrteilige Ausführung des Ventilgehäuses erleichtert die Fertigung bzw. Montage des Tankventils.Furthermore, the valve piston is preferably designed as a stepped piston, which means that the valve piston forms at least one step. The valve piston designed as a stepped piston interacts with a shoulder of the valve housing to form a stop. For this purpose, the step is designed at the end of the valve piston that faces away from the valve seat. To form the shoulder, the valve housing is preferably designed in several parts. The multi-part design of the valve housing facilitates the manufacture and assembly of the tank valve.

Der Filter des Tankventils ist vorzugsweise topfförmig ausgeführt und auf einem innenliegenden Kragenabschnitt des Ventilgehäuses angeordnet, der zugleich einen Ventileinlass ausbildet. Der Filter verhindert auf diese Weise, dass schädliche Partikel in das Tankventil und in die Speicherleitung eingetragen werden. Die Topfform des Filters gewährleistet einen sicheren Sitz des Filters auf dem Kragenabschnitt des Ventilgehäuses. Beispielsweise kann der Filter auf den Kragenabschnitt aufgeklemmt oder aufgepresst werden.The filter of the tank valve is preferably pot-shaped and arranged on an inner collar section of the valve housing, which also forms a valve inlet. In this way, the filter prevents harmful particles from entering the tank valve and the storage line. The pot shape of the filter ensures that the filter sits securely on the collar section of the valve housing. For example, the filter can be clamped or pressed onto the collar section.

Da die erfindungsgemäße Vorrichtung zum Speichern von Druckgas bevorzugt in einem Fahrzeug zum Einsatz gelangt, wird ferner ein Fahrzeug mit einer erfindungsgemäßen Vorrichtung vorgeschlagen. Bei dem Druckgas kann es sich insbesondere um Wasserstoff handeln, der zum Betreiben eines Brennstoffzellensystems oder eines Verbrennungsmotors benötigt wird. Bei dem Druckgas kann es sich aber auch um Erdgas handeln, das von einem Verbrennungsmotor des Fahrzeugs benötigt wird.Since the device according to the invention for storing compressed gas is preferably used in a vehicle, a vehicle with a device according to the invention is also proposed. The compressed gas can in particular be This could be hydrogen, which is needed to operate a fuel cell system or a combustion engine. The compressed gas could also be natural gas, which is needed by a vehicle's combustion engine.

Die Speicherleitung der Vorrichtung ist vorzugsweise über das Ventilgehäuse des Tankventils mit einer Tankleitung und/oder einem Tankanschluss verbunden, über die bzw. den die Speicherleitung mit Druckgas befüllbar ist.The storage line of the device is preferably connected via the valve housing of the tank valve to a tank line and/or a tank connection via which the storage line can be filled with compressed gas.

Weiterhin vorzugsweise ist in die Tankleitung oder in den Tankanschluss ein weiteres Tankventil integriert. Das heißt, dass eine weitere Absicherung bewirkt wird, so dass bei einem etwaigen Defekt des in die Speicherleitung integrierten Tankventils die Absperr- und Sicherheitsfunktion des weiteren Tankventils wirkt. Die Redundanz erhöht somit die Sicherheit.Furthermore, an additional tank valve is preferably integrated into the tank line or the tank connection. This means that additional protection is provided so that if the tank valve integrated into the storage line is defective, the shut-off and safety function of the additional tank valve is activated. The redundancy therefore increases safety.

Ausführliche Beschreibung der ZeichnungenDetailed description of the drawings

Die in der Fig. 1 dargestellte Vorrichtung zum Speichern von Druckgas umfasst eine gemeinsame Speicherleitung 1 für mehrere anschließbare Druckgasbehälter (nicht dargestellt). Die gemeinsame Speicherleitung 1, die auch als "Rail" bezeichnet werden kann, weist einen stirnseitigen Endabschnitt 2 auf, in den ein Tankventil 3 integriert ist. Über das Tankventil 3 kann die Speicherleitung 1 mit einem Druckgas, beispielsweise mit Wasserstoff, befüllt werden.The Fig.1 The device shown for storing compressed gas comprises a common storage line 1 for several connectable compressed gas containers (not shown). The common storage line 1, which is also referred to as a "rail" has a front end section 2 into which a tank valve 3 is integrated. The storage line 1 can be filled with a compressed gas, for example hydrogen, via the tank valve 3.

Wie insbesondere den Figuren 2 bis 4 zu entnehmen ist, weist das Tankventil 3 ein Ventilgehäuse 4 auf, in dem ein Filter 5 aufgenommen ist. Der Filter 5 ist topfförmig ausgebildet und auf einen innenliegenden Kragenabschnitt 14 des Ventilgehäuses 4 aufgepresst, der zugleich einen Ventileinlass 15 ausbildet. Der Kragenabschnitt 14 bzw. der Ventileinlass 15 ist von einem Ventilgehäuseabschnitt umgeben, der einen Druckgas-Anschluss 6 ausbildet. Der den Druckgas-Anschluss 6 ausbildende Ventilgehäuseabschnitt ist außerhalb der Speicherleitung 1 angeordnet, so dass er mit einer Tankleitung (nicht dargestellt) verbunden werden kann. Die Abdichtung zwischen dem Ventilgehäuse 4 des Tankventils 3 und der Speicherleitung 1 wird mit Hilfe eines Dichtelements 7 bewirkt, welches das Ventilgehäuse 4 außenumfangseitig umgibt und unter einer radialen Vorspannung an der Speicherleitung 1 anliegt. Die axiale Lage des Ventilgehäuses 4 in Bezug auf die Speicherleitung 1 ist mit Hilfe eines Sprengrings 17 gesichert.As in particular the Figures 2 to 4 , the tank valve 3 has a valve housing 4 in which a filter 5 is accommodated. The filter 5 is pot-shaped and pressed onto an inner collar section 14 of the valve housing 4, which at the same time forms a valve inlet 15. The collar section 14 or the valve inlet 15 is surrounded by a valve housing section which forms a compressed gas connection 6. The valve housing section forming the compressed gas connection 6 is arranged outside the storage line 1 so that it can be connected to a tank line (not shown). The seal between the valve housing 4 of the tank valve 3 and the storage line 1 is brought about by means of a sealing element 7 which surrounds the valve housing 4 on the outer circumference and rests against the storage line 1 under radial prestress. The axial position of the valve housing 4 in relation to the storage line 1 is secured by means of a snap ring 17.

Im Ventilgehäuse 4 des Tankventils 3 ist ein Ventilkolben 8 hin und her beweglich aufgenommen und über das Ventilgehäuse 4 geführt. Der Ventilkolben 8 ist in Richtung eines Ventilsitzes 9 von der Federkraft einer Feder 10 beaufschlagt, so dass über den federbelasteten Ventilkolben 8 eine Absperrfunktion realisiert wird. Der Ventilkolben 8 wirkt dabei mit einem kugelförmigen Ventilschließelement 11 zusammen. In der Figur 2 ist das Tankventil 3 in geschlossenem Zustand dargestellt. Das Ventilschließelement 11 liegt dichtend am Ventilsitz 9 an. In der Figur 3 ist das Tankventil 3 in einem geöffneten Zustand dargestellt. Das heißt, dass das Ventilschließelement 11 einen Druckgas-Strömungspfad freigibt, der über den Ventileinlass 15 und den Ventilsitz 9 führt und seine Fortsetzung in Längsnuten 12 findet, die im Ventilkolben 8 ausgebildet sind (siehe Figur 4).A valve piston 8 is accommodated in the valve housing 4 of the tank valve 3 so that it can move back and forth and is guided over the valve housing 4. The valve piston 8 is acted upon in the direction of a valve seat 9 by the spring force of a spring 10, so that a shut-off function is realized via the spring-loaded valve piston 8. The valve piston 8 interacts with a spherical valve closing element 11. In the Figure 2 the tank valve 3 is shown in the closed state. The valve closing element 11 is in sealing contact with the valve seat 9. In the Figure 3 the tank valve 3 is shown in an open state. This means that the valve closing element 11 releases a compressed gas flow path that leads over the valve inlet 15 and the valve seat 9 and continues in longitudinal grooves 12 that are formed in the valve piston 8 (see Figure 4 ).

Wie insbesondere den Figuren 2 und 3 zu entnehmen ist, ist der Ventilkolben 8 als Stufenkolben ausgeführt. Der Ventilkolben 8 bildet demnach eine Stufe 16 aus, die mit einem Absatz 13 des Ventilgehäuses 4 einen Anschlag ausbildend zusammenwirkt. Zur Ausbildung des Absatzes 13 ist das Ventilgehäuse 4 mehrteilig ausgeführt. Das den Absatz 13 ausbildende Gehäuseteil des Ventilgehäuses nimmt zugleich die Feder 10 auf, so dass ein kompaktes Tankventil 3 geschaffen wird.As in particular the Figures 2 and 3 As can be seen from the drawing, the valve piston 8 is designed as a stepped piston. The valve piston 8 therefore forms a step 16, which interacts with a shoulder 13 of the valve housing 4 to form a stop. To form the shoulder 13, the valve housing 4 is designed in several parts. The housing part of the valve housing forming paragraph 13 simultaneously accommodates the spring 10, so that a compact tank valve 3 is created.
