Description
Stand der TechnikState of the art
Die vorliegende Erfindung geht von einem Gaseinblasventil zum Einblasen eines Gases gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art aus.The present invention is based on a gas injection valve for injecting a gas according to the closer defined in the preamble of claim 1. Art.
Ein derartiges Ventil ist aus der Praxis bekannt und beispielsweise ein Gassteuerventil, das bei einem Gasmotor oder auch bei einer Brennstoffzelle eines Kraftfahrzeugs einsetzbar ist.Such a valve is known from practice and for example a gas control valve which can be used in a gas engine or even in a fuel cell of a motor vehicle.
Ein bekanntes Ventil der einleitend genannten Art, mittels dessen ein Verbrennungsgas in ein Saugrohr eines Gasmotors eingespritzt wird, umfasst ein Ventilgehäuse, in dem eine elektromagnetisch ausgeführte Betätigungseinheit für ein Ventilschließglied angeordnet ist, das Bestandteil eines Magnetankers ist, der wiederum durch die Betätigungseinheit ansteuerbar ist. Der Magnetanker ist in einer dem Ventilgehäuse zugeordneten Hülse axial verschiebbar geführt. Das an dem Magnetanker ausgebildete Ventilschließglied wirkt mit einem Ventilsitz zusammen, der an einer Ventilplatte ausgebildet ist, die in der Hülse fixiert ist. In Abhängigkeit von der Stellung des Magnetankers bzw. des Ventilschließglieds ist ein Fluidstrom von einer Zuströmseite zu einer Abströmseite des Ventils steuerbar.A known valve of the aforementioned type, by means of which a combustion gas is injected into a suction pipe of a gas engine, comprises a valve housing, in which an electromagnetically designed actuator unit is arranged for a valve closing member which is part of a magnet armature, which in turn is actuated by the actuating unit. The armature is guided axially displaceably in a sleeve associated with the valve housing. The valve closing member formed on the armature cooperates with a valve seat formed on a valve plate fixed in the sleeve. Depending on the position of the magnet armature or of the valve closing member, a fluid flow from an inflow side to an outflow side of the valve can be controlled.
Bei einem Einsatz in Verbindung mit einem Gasmotor werden in vorstehend beschriebener Art ausgebildete Gasventile bisher in der Regel aus einbautechnischen Gründen in einem steilen Winkel, beispielsweise in einem Winkel zwischen 45° und 90° zu der Achse des Saugrohrs eingebracht. Aufgrund dieser Anordnung entsteht beim Einblasen des Gases in das Saugrohr in diesem ein Gaskissen, das als Sperrschicht für Luft wirkt, die durch das Saugrohr in Richtung eines Zylinders des Gasmotors gefördert wird. Dies hat zur Folge, dass beim Öffnen des Zylinders nicht die zur Verbrennung erforderliche Menge an Luft in den Zylinder eingefördert wird.When used in conjunction with a gas engine trained in the manner described above gas valves are hitherto usually introduced for structural reasons at a steep angle, for example at an angle between 45 ° and 90 ° to the axis of the intake manifold. Due to this arrangement, when the gas is blown into the suction tube, it forms a gas cushion which acts as a barrier to air which is conveyed through the suction tube in the direction of a cylinder of the gas engine. This has the consequence that when opening the cylinder, the amount of air required for combustion is not conveyed into the cylinder.
Ferner ist es bei dem in vorstehend beschriebener Art ausgeführten Ventil nachteilig, dass es betriebsbedingt zu einer unerwünschten Geräuschentwicklung kommen kann.Furthermore, it is disadvantageous in the case of the valve designed in the manner described above that, due to operational reasons, undesired noise generation can occur.
Der Erfindung liegt die Aufgabe zugrunde, ein Ventil der einleitend genannten Art mit einer Einrichtung zu versehen, mittels der den oben genannten Nachteilen in spezifischer Weise entgegengesteuert werden kann.The invention has for its object to provide a valve of the aforementioned type with a device by means of which the abovementioned disadvantages can be counteracted in a specific manner.
Neben solchen wie z. B. aus der
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Gaseinblasventil zum Einblasen eines Gases mit den Merkmalen des Oberbegriffs des Patentanspruches 1, bei welchem Ventil stromab des Ventilsitzes in der Hülse eine Funktionsplatte angeordnet ist, die den Querschnitt der Hülse ausfüllt, zeichnet sich mithin durch eine zusätzliche Einrichtung aus, mit der das Ventil an bestimmte Anforderungen angepasst werden kann. So kann die Funktionsplatte beispielsweise zur Geräuschreduzierung und/oder Gasumlenkung genutzt werden.The gas injection valve according to the invention for injecting a gas with the features of the preamble of claim 1, wherein valve downstream of the valve seat in the sleeve, a function plate is arranged, which fills the cross section of the sleeve, thus characterized by an additional device with which the valve can be adapted to specific requirements. Thus, the function panel can be used for example for noise reduction and / or gas deflection.
Das Ventil nach der Erfindung ist insbesondere zur Massenstromregelung von Gasen wie Wasserstoff und Erdgas geeignet und kann beispielsweise in Verbindung mit einer Brennstoffzelle oder auch bei einem Gasmotor eines Kraftfahrzeuges eingesetzt werden.The valve according to the invention is particularly suitable for mass flow control of gases such as hydrogen and natural gas and can be used for example in conjunction with a fuel cell or even in a gas engine of a motor vehicle.
Bei einer speziellen Ausführungsform des Ventils nach der Erfindung ist die Funktionsplatte ein Dämmkörper zur Reduzierung von betriebsbedingten Geräuschen des Ventils. Dies führt bei einem Einsatz in Verbindung mit einem Kraftfahrzeug, beispielsweise bei einem Gasverbrennungsmotor, zu einer Geräuschreduzierung am Fahrzeug.In a specific embodiment of the valve according to the invention, the functional plate is a damping body for reducing operating noise of the valve. When used in conjunction with a motor vehicle, for example in a gas combustion engine, this leads to a noise reduction on the vehicle.
Der Dämmkörper umfasst beispielsweise einen gasdurchlässigen Sinterkörper. Ein Sinterkörper stellt in der Regel ein chemisch stabiles Bauteil dar und zeichnet sich damit durch eine Langlebigkeit aus.The insulating body comprises, for example, a gas-permeable sintered body. A sintered body is usually a chemically stable component and is characterized by a longevity.
Zur Befestigung des nach dem Prinzip eines Absorptionsschalldämpfers ausgelegten Dämmkörpers kann dieser ein perforiertes Gehäuse umfassen, das beispielsweise einen Gehäusetopf aufweist, in dem ein Dämmstoff, wie Dämmwolle oder auch ein gasdurchlässiger Sinterkörper, angeordnet ist und der mittels eines Gehäusedeckels verschlossen ist.To attach the designed according to the principle of an absorption silencer insulating body this may comprise a perforated housing having, for example, a housing pot in which an insulating material, such as insulating wool or a gas-permeable sintered body, is arranged and which is closed by means of a housing cover.
Alternativ kann der Dämmkörper auch einen mindestens einlagig ausgebildeten Spritzgusskunststoffkörper mit einer Perforierung aufweisen, die einen Gasstrom zulässt.Alternatively, the insulating body can also have an injection-molded plastic body with a perforation which is at least single-layered and permits a gas flow.
Bei einer Ausbildung der Funktionsplatte als Dämmkörper kann diese zur Verbesserung des Dämmverhaltens auch axial aus einer abströmseitig angeordneten Ventilöffnung herausragen.In an embodiment of the functional plate as an insulating body, it can also protrude axially from a valve opening arranged downstream to improve the insulating behavior.
Die Funktionsplatte ist bei einer weiteren speziellen Ausführungsform des Ventils nach der Erfindung als Umlenkplatte ausgebildet, die gewährleistet, dass an der Abströmseite des Ventils eine definierte, hinsichtlich den jeweiligen Anforderungen optimierte und definierte Gasumlenkung erfolgt. The functional plate is formed in a further specific embodiment of the valve according to the invention as a baffle, which ensures that on the downstream side of the valve, a defined, with respect to the respective requirements optimized and defined gas deflection takes place.
Bei Anwendung eines Ventils mit einer Umlenkplatte in Verbindung mit einem Gasverbrennungsmotor kann gegenüber dem Einsatz eines Ventils ohne Umlenkplatte an der Abströmseite eine deutliche Verbesserung des Verbrennungsverhaltens in dem Gasverbrennungsmotor erreicht werden, da durch ein gerichtetes Einbringen des Brenngases in das Saugrohr verhindert werden kann, dass sich beim Einbringen des Brenngases mittels des Ventils in ein zu einem Zylinder des Gasverbrennungsmotors führendes Saugrohr in diesem ein als Sperrschicht für Luft wirkendes Gaskissen ausbildet. Die Umlenkplatte führt zu einer Verbesserung des Gasströmungsverhaltens in dem nachgeschalteten Saugrohr. Dies führt wiederum zu einer erhöhten Leistung bzw. einer verbesserten Dynamik des Gasverbrennungsmotors.When using a valve with a baffle in conjunction with a gas combustion engine can be compared to the use of a valve without baffle on the downstream side significantly improved combustion performance in the gas combustion engine can be achieved, as can be prevented by a directed introduction of the fuel gas into the intake manifold that when introducing the fuel gas by means of the valve into a leading to a cylinder of the gas combustion engine suction pipe in this acts as a barrier layer for air acting gas cushion. The baffle leads to an improvement of the gas flow behavior in the downstream intake manifold. This in turn leads to increased performance and improved dynamics of the gas combustion engine.
Eine spezielle Ausführungsform der Umlenkplatte weist lineare Kanäle auf, die zum Umlenken des durch das Ventil zu fördernde Gas gegenüber der Achse des Ventils angestellt sind.A special embodiment of the baffle plate has linear channels, which are employed for deflecting the gas to be delivered through the valve with respect to the axis of the valve.
Die Querschnittsfläche der linearen Kanäle sollte mindestens zweimal größer sein als der im Bereich des Ventilsitzes definierte Zumessquerschnitt. Damit wird gewährleistet, dass die Hauptdrosselstelle des Ventils im Bereich des Ventilsitzes angeordnet ist.The cross-sectional area of the linear channels should be at least twice as large as the metering cross-section defined in the area of the valve seat. This ensures that the main throttle point of the valve is located in the region of the valve seat.
Die Umlenkplatte ist vorzugsweise aus Kunststoff oder Metall gefertigt. Die Herstellung der Umlenkplatte kann nach einem Spritzgieß- bzw. einen MEM(Metal Ejection Moulding)-Verfahren erfolgen.The baffle plate is preferably made of plastic or metal. The production of the baffle plate can be carried out by an injection molding or a MEM (Metal Ejection Molding) process.
Die linearen Kanäle der Umlenkplatte bilden mit der Achse des Ventils einen Winkel von beispielsweise zwischen 0° und 60°. Dieser Winkel bestimmt die Ausströmrichtung des Gases aus dem Ventil.The linear channels of the baffle form with the axis of the valve at an angle of for example between 0 ° and 60 °. This angle determines the outflow direction of the gas from the valve.
Denkbar ist es auch, ein Ventil mit einer als Umlenkplatte ausgebildeten Funktionsplatte und einer als Dämmkörper ausgebildeten Funktionsplatte auszulegen. In diesem Falle ist zu beachten, dass die Umlenkplatte stromab des Dämmkörpers angeordnet ist.It is also conceivable to design a valve with a function plate designed as a deflection plate and a function plate designed as a damping body. In this case, it should be noted that the baffle plate is located downstream of the insulating body.
