Description

Umschaltvorrichtung für die Zufuhr eines unter Druck stehenden Fluidums zu einem Verbraucher Zusatz zur Anmeldung: E 18046 XII / 47 g - Auslegeschrift 1 155 646 Die Erfindung bezieht sich auf eine Umschaltvorrichtung für die Zufuhr eines unter Druck stehenden Fluidums, wie Butan, Propan od. dgl., zu einem Verbraucher, z. B. einem Brenner von mehreren Quellen für das Fluidum, mit einer Membran, die auf ihrer einen Seite vom Druck der Umgebung sowie durch eine tarierte Feder und auf ihrer anderen Seite vom Druck des Fluidums in der Zuleitung zum Verbraucher beaufschlagt ist und eines der Ventile in geöffnetem und die übrigen Ventile so lange in geschlossenem Zustand hält, bis der Druck der an das geöff- nete, Ventil angeschlossenen Quelle unter einen vorbestimmten Wert sinkt, um dann während ihrer Vorbewegung auf das nächste Ventil über eine mit ihr verbundene abgesehrägte Leitfläche aufzutreffen und es zu öffnen, deren Lage zwecks Veränderung der Reihenfolge der zu öffnenden Ventile verstellbar ist, nach Patentanmeldung E 18046 XII/47,g. Beim Gegenstand der Hauptpatentanmeldung ist die Leitfläche Teil eines Nockens, der mit der Membran verbunden ist und sich unmittelbar auf den von ihr gesteuerten Vontilschäften abstützt. Bei Verstellen des Nockens gleitet infolgedessen die Leitfläch#e des Nockens mit recht erheblicher Reibung auf den Köp- fen der Ventilschäfte. Es besteht die Gefahr, daß in manchen Fällen durch diese Reibung ein genaues Arbeiten der Ventile verhindert wird, vor allem dann, wenn sieh nach längerer Betriebszeit ein spürbarer Verschleiß der in Reibkontakt befindlichen Teile zeigt.Switching device for the supply of a pressurized fluid to a consumer Addition to the application: E 18046 XII / 47 g - Auslegeschrift 1 155 646 The invention relates to a switching device for the supply of a pressurized fluid, such as butane, propane or the like ., to a consumer, e.g. B. a burner from several sources for the fluid, with a membrane which is acted upon on its one side by the pressure of the environment and by a tared spring and on its other side by the pressure of the fluid in the supply line to the consumer and one of the valves in and the other valves are kept in the closed state until the pressure of the source connected to the open valve falls below a predetermined value to open, the position of which is adjustable in order to change the sequence of the valves to be opened, according to patent application E 18046 XII / 47, g. In the subject of the main patent application, the guide surface is part of a cam which is connected to the membrane and is directly supported on the Vontile shafts controlled by it. As a result, when the cam is adjusted, the guide surface of the cam slides with considerable friction on the heads of the valve stems. There is a risk that, in some cases, this friction will prevent the valves from working accurately, especially if, after a long period of operation, there is noticeable wear on the parts in frictional contact.

Aufgabe der Erfindung ist es, die Umschaltvorrichtung der eingangs genannten Art so weiter auszugestalten, daß nachteilige Reibungseinflüsse weitgehend ausgeschaltetsind.The object of the invention is the switching device of the opening to further develop said type so that adverse frictional influences largely are switched off.

Die exfindungsgemäße Vorrichtung zeichnet sich im wesentilichen dadurch aus, daß die von der Membran bewegbare Leitfläche durch eine Platte, gebildet wird, die gegen Drehung und Verschiebung quer zu den Ventilen gesichert, jedoch um eine oder mehrere in ihrer Ebene liegende Achsen kippb#ar ist, so daß sie der gewünschten Ventilbetätigungs-Reihenfolge entsprechend verschiedene Schräglagen einnehmen kann. Zwischender bei der erfindungsgemäßen Vorrichtung die Leitfläche bildenden Platte und den Ventilschäften findet somit keine relative Drehbewegung mehr statt, wodurch Reibungseinflüsse weitgehend vermieden sind.The device according to the invention is essentially characterized by this from that the guide surface movable by the membrane is formed by a plate, secured against rotation and displacement across the valves, but by one or several axes lying in their plane can be tilted so that they are the desired Valve actuation sequence can assume different inclinations accordingly. Between the plate forming the guide surface in the device according to the invention and the valve stems thus no longer take place relative rotational movement, as a result of which Frictional influences are largely avoided.

Gemäß,einem weiteren wesentlichen Merkmal der Erfindung ist zur Verstellung der Schräglage der Platte e#n von außen drehbarer, die Membran durchsetzender und von ihr mitgeführter Zapfen nüt einer Schulter vorgesehen, deren Ebene mit der auf der Zapfenachse senkrecht stehenden Ebene einen spitzen Winkel einschließt und an dersich die, Platte abstützt. Dabei hat es sich als sehr zweckmäßig herausgestellt, Anschläge, vorzusehen, die in Ausnehmungen der Platte eingreifen, um sie gegen Drehung bei Drehung des Zapfens mit der Schulter zu sichern. In sehr vorteilhafter Weise sind diese Anschlägean einer Scheibe angeordnet, die der Führung der Sch#äfte der Ventile dient.According to a further essential feature of the invention is for adjustment the inclined position of the plate e # n rotatable from the outside, penetrating the membrane and of her carried pin nüt provided a shoulder, the plane of which with the on the plane perpendicular to the pin axis encloses an acute angle and which is supported by the plate. It has proven to be very useful Stops to be provided which engage in recesses in the plate to prevent them from rotating to be secured with the shoulder when turning the pin. In a very beneficial way these stops are arranged on a disc that guides the shafts of the Valves is used.

Weitere wesentliche Einzelheiten, Vorteile und Merkmalee der Erfindung ergeben sich aus der Beschreibung.Further essential details, advantages and features of the invention result from the description.

In der Zeichnung ist dieErfliidung näher erläutert, und zwar zeigt F i g. 1 einen Längsschnitt durch die Umschaltvorrichtung nach der Erfindung und Flg. 2 einen Längsschnitt durch die Vorrichtung gemäß der Linie II-II der F i g. 1. The invention is explained in more detail in the drawing, namely FIG . 1 shows a longitudinal section through the switching device according to the invention and Flg. 2 shows a longitudinal section through the device according to the line II-II in FIG. 1.

Bei dem dargestellten Ausführungsbeispiel besitzt die Vorrichtung ein Gehäuse 71 mit zwei Kanälen 72 und 73, die eine Kammer 74 mit nicht dargestellten Brennstoffquellen verbinden. Obwohl in der Zeichnung nur zwei Kanäle dargestellt sind, kann natürlich auch eine größere Zahl verwendet werden. Die Kanäle 72 und 73 werden durch Ventile 75 und 76 geschlossen, die unter der Einwirkung von Rückholfedern 77 und 78 stehen. Die Ventile besitzen in Köpfe 81 und 82 auslaufende Schäfte 79 und 80. Die Ventilschäfte 79 und 80 durchsetzen eine Scheibe 83, die längs der Schäfte gleiten kann, aber gegen Drehung durch in das Gestell 71 eingesetzte Stifte 84 und 85 gesichert ist (s. F i g. 2).In the exemplary embodiment shown, the device has a housing 71 with two channels 72 and 73 which connect a chamber 74 to fuel sources (not shown). Although only two channels are shown in the drawing, a larger number can of course be used. The channels 72 and 73 are closed by valves 75 and 76 which are under the action of return springs 77 and 78 . The valves have the valve stems 79 and 80 in heads 81 and 82 outgoing shafts 79 and 80 pass through a washer 83, which can slide the stems along, but against rotation by inserted into the frame 71 pins 84 and is secured 85 (s. F i g. 2).

Die Scheibe 83 steht mit einem Zapfen 86 in Berührung, der mit einem außerhalb des Gehäuses befindlichen Betätigungsgriff drehschlüssig verbunden ist. Der Zapfen 86 ist mit einer Membran 88 verbunden, die den Druckschwankungen in der Kammer 74 folgt.The disk 83 is in contact with a pin 86 which is connected in a rotationally locking manner to an actuating handle located outside the housing. The pin 86 is connected to a diaphragm 88 which follows the pressure fluctuations in the chamber 74.

Am den Ventilen zugewandten Ende des Zapfens 86 ist ein Stab 89 befestigt, der in einer Ausnehrnung 90 des Gehäuses gleitet und zur Führung dient.At the end of the pin 86 facing the valves, a rod 89 is attached, which slides in a recess 90 of the housing and serves as a guide.

Der Zapfen 86 ist mit einer sich über seinen Umfang erstreckenden Schulter 91 versehen, deren Ebene mit der auf der Achse des Zapfens 86 senkrecht stehenden Ebene einen spitzen Winkel einschließt. An der Schulter 91 stützt sich eine z. B. durch einen Ring 93 an Ort und Stelle gehaltene Platte 92 ab. Zwischen der Schulter 91 und dem Ring 93 ist die Platte 92 mit einem so großen Spiel gelagert, daß zwischen der Platte und dem Zapfen eine relative Drehbewegung möglich ist. Die Platte 92, die auf den Ventilschäften 79 und 80 ruht, ist mit vertieften Stellen 94 und 95 für die Aufnahme der Köpfe der Schäfte 79 und 80 versehen. Anschläge 96 und 97 hindern die Platte 92, der Drehung des Zapfens 86 zu folgen. Diese Anschläge können z. B. an der Scheibe 83 befestigt sein. Die Platte 92 besitzt öffnungen oder Nuten für den Durchtritt der Anschläge 96 und 97, so daß die Platte zwar senkrecht gleiten, aber sich nicht drehen kann.The pin 86 is provided with a shoulder 91 extending over its circumference, the plane of which encloses an acute angle with the plane perpendicular to the axis of the pin 86. On the shoulder 91 a such supports. B. held in place by a ring 93 plate 92 from. Between the shoulder 91 and the ring 93 , the plate 92 is mounted with such a large play that a relative rotary movement is possible between the plate and the pin. The plate 92 which rests on the valve stems 79 and 80 is provided with recessed points 94 and 95 for receiving the heads of the shafts 79 and 80th Stops 96 and 97 prevent plate 92 from following the rotation of pin 86 . These attacks can, for. B. be attached to the disc 83 . The plate 92 has openings or grooves for the stops 96 and 97 to pass through, so that the plate can slide vertically but cannot rotate.

In der in F i g. 1 dargestellten Stellung ist angenommen, daß das Ventil 75 mit der zugehörigen Brennstoffquelle betriebsbereit ist. Sobald ein Unterdruck in der Kammer 74 auftritt, geht die Membran 88 abwärts und nimmt den Zapfen 86 mit. Die Platte 92 folgt dieser Bewegung und öffnet das Ventil 75 durch Druck auf den Kopf 81 des Schaftes 79. In the in F i g. 1 , it is assumed that the valve 75 with the associated fuel source is ready for operation. As soon as a negative pressure occurs in the chamber 74, the diaphragm 88 goes down and takes the pin 86 with it. The plate 92 follows this movement and opens the valve 75 by pressing on the head 81 of the shaft 79.

Wenn die zu dem Ventil 75 gehörende Brennstoffquelle erschöpft ist, wird der Griff 87 in dem gewünschten Sinn verdreht. Die Schulter 91 kommt dann in die F i g. 1 strichpunktiert dargestellte Stellunz, in der sich die Platte 92 nach einer Kippbewegung mit der vertieften Stelle 95 auf den Kopf 82 des Schaftes 80 des Ventils 76 legt. Die Urnschaltvorrichtung ist dann mit der zu diesem Ventil gehörenden Brennstoffquelle betriebsbereit.When the fuel source associated with valve 75 is exhausted, handle 87 is rotated in the desired direction. The shoulder 91 then comes into FIG. 1 position shown in dash-dotted lines, in which the plate 92 lies with the recessed point 95 on the head 82 of the shaft 80 of the valve 76 after a tilting movement. The switching device is then ready for operation with the fuel source belonging to this valve.
