Den Gegenstand vorliegender Erfindung bildet ein kombiniertes Regel- und Einlaßventil für Gasmaschinen, durch welches bezweckt wird, eine gedrängte Anordnung der erforderlichen Gas- und Lufteinlaßorgane zu erzielen, den Rückdruck des Regelventils auf den Regulator zu vermindern und eine genaue Regelung bei allen Belastungen der Maschine zu erreichen.The subject of the present invention is a combined control and inlet valve for gas machines, the purpose of which is to provide a compact arrangement of the required gas and air inlet organs achieve to reduce the back pressure of the control valve on the regulator and an accurate Achieve control for all machine loads.
In der beiliegenden Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform dargestellt.The subject of the invention is shown in an exemplary manner in the accompanying drawing Embodiment shown.
Gemäß vorliegender Erfindung ist die Anordnung derart getroffen, daß in bekannter Weise die Achse eines als Doppelsitzventil ausgebildeten Regelventils jR mit der eines nur aus einem einfachen Kegelventil bestehenden Einlaßventils E zusammenfällt und daß der Sitz und damit der Hub des einen Ventils dem des anderen entgegengesetzt ist. Das Doppelsitzventil R, dessen Hub nach der Leistung der Maschine sich ändert, regelt in annähernd gleichem Mischungsverhältnis einerseits den Eintritt von Luft durch eine Luftzuleitung L, andererseits den Zufluß von Gas durch die Gaszuleitung G. Das Einlaßventil E, dessen Hub hingegen konstant ist, schließt die Ventilkammer vom Verbrennungsraum V ab.According to the present invention, the arrangement is such that, in a known manner, the axis of a control valve designed as a double seat valve coincides with that of an inlet valve E consisting only of a simple cone valve and that the seat and thus the stroke of one valve is opposite to that of the other. The double seat valve R, the stroke of which changes according to the performance of the machine, regulates in approximately the same mixing ratio on the one hand the entry of air through an air supply line L and on the other hand the inflow of gas through the gas supply line G. The inlet valve E, whose stroke is constant, closes the valve chamber from the combustion chamber V.
Die Wirkungsweise dieses kombinierten Ventils ist folgende:The mode of operation of this combined valve is as follows:
Beim Öffnen des Einlaßventils E während des Saughubes der Maschine wird beim Anheben des doppelseitigen Regelventils R einerseits Gas aus der Gaszuleitung G, andererseits Luft aus der Luftzuleitung L angesaugt. Gas und Luft mischen sich vor dem Einlaßventil in einem Mischkanal M, und das Gemisch gelangt durch das Einlaßventil in den Verbrennungsraum V. When the inlet valve E opens during the suction stroke of the machine, when the double-sided control valve R is raised, gas is sucked in from the gas supply line G on the one hand and air from the air supply line L on the other. Gas and air mix in front of the inlet valve in a mixing channel M, and the mixture passes through the inlet valve into the combustion chamber V.
Die Vorteile, welche durch diese Art der Anordnung erreicht werden, sind, daß einerseits infolge der durch das Doppelsitzventil bewirkten Entlastung die Kraft zum Anheben des Regelventils klein gehalten werden kann, und daß andererseits durch die Anordnung des Regelventils unmittelbar über dem Einlaßventil der Raum zwischen beiden Ventilen sehr beschränkt wird, was für die genaue Regelung namentlich bei geringen Belastungen von Wert ist. Außerdem wird bei geringen Füllungen das Regelventil durch die Saugwirkung auf seinen Sitz gezogen, so daß ein dichter Abschluß möglich ist, ohne daß es erforderlich wäre, die Feder besonders kräftig auszuführen.The advantages that are achieved by this type of arrangement are that on the one hand due to the relief caused by the double seat valve, the force to lift of the control valve can be kept small, and that on the other hand by the arrangement of the control valve is the space between the two valves immediately above the inlet valve is very limited, which is necessary for the precise regulation, especially in the case of low loads is of value. In addition, when the fillings are low, the control valve is activated by the suction effect pulled onto its seat so that a tight seal is possible without the need for the spring to be particularly strong to execute.
