Abstract
Description
Die Erfindung betrifft ein Ventil zum Einblasen von Gas gemäß Patentanspruch 1.The The invention relates to a valve for blowing gas according to claim 1.
Bei Erdgasfahrzeugen wird Gas in der Regel in Flaschen mit Drücken von bis zu 200 bar gelagert. Aus diesem Grund wird ein Druckverminderer benötigt, der das Gas von dem Hochdruck auf einen niedrigen Raildruck am Eingang der Ventile reduziert. Die Ventile sind beispielsweise als Magnetventile ausgebildet, die abhängig von der Bestromung das Gas in einen Brennraum der Brennkraftmaschine abgeben.at Natural gas vehicles are usually bottled with pressures of gas stored up to 200 bar. For this reason, a pressure reducer needed the gas from the high pressure to a low rail pressure at the entrance the valves are reduced. The valves are for example as solenoid valves trained, the dependent from the energization of the gas in a combustion chamber of the internal combustion engine submit.

Die Aufgabe der Erfindung besteht darin, ein verbessertes Ventil zum Einblasen von Gas bereitzustellen.The The object of the invention is to provide an improved valve for To provide injection of gas.
Die Aufgabe der Erfindung wird durch das Ventil gemäß Patentanspruch 1 gelöst.The The object of the invention is achieved by the valve according to claim 1.
Weitere vorteilhafte Ausführungsformen des Ventils sind in den abhängigen Ansprüchen angegeben.Further advantageous embodiments of the valve are in the dependent ones claims specified.
Das erfindungsgemäße Ventil hat den Vorteil, dass das Ventil mit geringen Magnetkräften betätigt werden kann. Dazu ist ein Stellglied und ein Schließglied vorgesehen, wobei das Stellglied in der Schließposition einen geringen Abstand zur Magnetspule aufweist. Das Stellglied steht in Wirkverbindung mit dem Schließglied in der Weise, dass bei einer Bestromung der Magnetspule das Stellglied das Schließglied in Richtung auf die Magnetspule mitbewegt. Zudem wird das Schließglied durch Magnetkräfte der Magnetspule unabhängig von der Bewegung des Stellgliedes noch näher an die Magnetspule bis zu einer Offenposition herangezogen. Durch das Vorsehen des Stellgliedes und des Schließgliedes ist es möglich, mit einer ersten Bewegung des Stellgliedes und einer damit verbundenen Bewegung des Schließgliedes eine Abgabeöffnung des Ventils zu öffnen. Dabei sinkt der Druck in einem Abgaberaum, in dem sich das Stellglied und das Schließglied befinden. Damit ist der Gasdruck und die damit verbundenen Kräfte auf das Schließglied reduziert. Somit kann eine weitere Bewegung des Schließgliedes in eine Offenposition, in der die Abgabeöffnung vollständig geöffnet ist, mit geringen Magnetkräften erreicht werden.The inventive valve has the advantage that the valve can be operated with low magnetic forces can. For this purpose, an actuator and a closing member is provided, wherein the Actuator in the closed position has a small distance from the solenoid. The actuator is in operative connection with the closing member in such a way that at an energization of the solenoid, the actuator, the closing member in Direction to the solenoid co-moved. In addition, the closing member is through magnetic forces the solenoid independent from the movement of the actuator even closer to the solenoid coil up used to an open position. By providing the actuator and the closing member Is it possible, with a first movement of the actuator and an associated Movement of the closing element a discharge opening to open the valve. The pressure drops in a delivery room in which the actuator and the closing member are located. Thus, the gas pressure and the associated forces on the closing member reduced. Thus, a further movement of the closing member in an open position, in which the discharge opening is completely open, achieved with low magnetic forces become.
In einer Weiterbildung der Erfindung ist der Abgaberaum mit einer Zuleitung für Gas verbunden, die durch die Magnetspule geführt ist. Dadurch wird ein kompakter Aufbau des Ventils ermöglicht.In a development of the invention is the delivery room with a supply line for gas connected, which is guided by the magnetic coil. This will be a compact Construction of the valve allows.
In einer weiteren Ausführungsform ist das Stellglied und/oder das Schließglied wenigstens in einem Teilbereich ringförmig ausgebildet, wobei der Teilbereich des Stellgliedes und/oder des Schließgliedes der Magnetspule zugewandt sind. Durch die ringförmige Ausbildung können die Magnetkräfte zwischen der Magnetspule und dem magnetischen Stellglied bzw. dem magnetischen Schließglied vergrößert werden.In a further embodiment is the actuator and / or the closing member at least in one Partial area annular formed, wherein the portion of the actuator and / or the closing member the magnetic coil facing. Due to the annular formation, the magnetic forces between the magnetic coil and the magnetic actuator or the magnetic closing element be enlarged.
In einer weiteren Ausführungsform des Ventils sind Betätigungsflächen am Schließglied und am Stellglied vorgesehen, über die das Schließglied vom Stellglied in Richtung Magnetspule bewegbar ist. Durch das Vorsehen von Betätigungsflächen ist ein einfaches und sicheres Mittel zur Ausbildung einer Wirkverbindung zwischen dem Stellglied und dem Schließglied möglich.In a further embodiment of the valve are actuating surfaces on closing member and provided on the actuator, via the closing member from the actuator in the direction of the solenoid is movable. By providing of actuating surfaces is a simple and safe means of forming an operative connection between the actuator and the closing member possible.
In einer weiteren Ausführungsform ist ein Federelement vorgesehen, das das Schließglied in eine Schließposition der Abgabeöffnung vorspannt. In einer weiteren Ausführungsform ist ein zweites Federelement vorgesehen, das das Stellglied in Richtung auf die Magnetspule vorspannt. Das Federelement weist eine größere Federsteifigkeit als das zweite Federelement auf. Damit ist ein sicheres Verschließen der Abgabeöffnung in der Schließposition möglich.In a further embodiment a spring element is provided which moves the closing member into a closed position the discharge opening biases. In a further embodiment, a second Spring element provided, which the actuator in the direction of the Magnetic coil pretensions. The spring element has a greater spring stiffness as the second spring element. This is a safe closing the discharge opening in the closed position possible.
In einer weiteren Ausführungsform weist das Stellglied einen ringförmigen Abschnitt auf, der einen ringförmigen Abschnitt des Schließgliedes umfasst, wobei die ringförmigen Abschnitte der Magnetspule zugewandt sind. Dadurch wird ein kompakter Aufbau mit einer vorteilhaften Ausbildungsform für die Magnetkräfte der Magnetspule bereitgestellt.In a further embodiment the actuator has an annular Section on, which is an annular Section of the closing member includes, wherein the annular Sections of the solenoid are facing. This will be a compact Structure with an advantageous embodiment for the magnetic forces of Magnetic coil provided.
In einer weiteren Ausführungsform weist die Magnetspule eine ringförmige Grundfläche auf, die sowohl wenigstens von einem Teil der ringförmigen Abschnitte des Stellgliedes und des Schließgliedes abgedeckt wird. Damit ist eine wirksame Anordnung des Schließgliedes und des Stellgliedes in Bezug auf die Magnetkräfte möglich.In a further embodiment the solenoid has an annular Floor space on, both at least part of the annular sections covered the actuator and the closing member becomes. This is an effective arrangement of the closing member and the actuator in relation to the magnetic forces possible.
In einer weiteren Ausführungsform sind das Stellglied und das Schließglied in der Weise ausgebildet, dass das Stellglied und das Schließglied in einer Offenposition in Anlage an die Magnetspule bringbar sind. Dadurch wird eine definierte Position des Stellgliedes und des Schließgliedes für die Offenposition der Abgabeöffnung bereitgestellt. Somit sind das Stellglied und das Schließglied in einer definierten Position, so dass deren Steuerung zum Schließen der Abgabeöffnung präzise festgelegt werden kann.In a further embodiment the actuator and the closing member are formed in the manner that the actuator and the closure member in an open position can be brought into contact with the magnetic coil. This will create a defined Position of the actuator and the closing member for the open position of the discharge opening provided. Thus, the actuator and the closing member are in a defined Position, so that their control to close the discharge opening precisely determined can be.
