In der DE 102 22 673 C1 wird ein Volumenstromregler mit einer schwenkbar in einem Strömungskanal angeordneten Klappe beschrieben, an der über einen Hebelarm ein Rückstellmechanismus eingreift, der eine Feder und eine Einstelleinrichtung zum Einstellen der Rückstellmomentkennlinie mit Hilfe eines Exzenters aufweist. Die Feder ist eine Zugfeder, die Einstelleinrichtung weist einen starren, um eine feste Schwenkachse schwenkbaren Stellhebel auf, der über ein die Zugfeder enthaltendes Zugglied mit dem Hebelarm verbunden ist und an dem der Exzenter angreift.In the DE 102 22 673 C1 describes a volume flow controller with a flap arranged pivotably in a flow channel, on which a resetting mechanism engages via a lever arm, which has a spring and an adjusting device for adjusting the resetting torque characteristic with the aid of an eccentric.

Die EP 1 921 394 A1 betrifft einen Mauerkasten mit einer Lüftungsöffnung an einem Führungsrohr und einem am Ende des Führungsrohres angeordneten, zwischen einer Schliessstellung und einer Offenstellung beweglichen Verschlussdeckel, wobei sich der Verschlussdeckel, getrieben von der Druckdifferenz zwischen dem Luftdruck in dem Führungsrohr und der äusseren Umgebungsluft, gegen eine Rückstellkraft selbsttätig öffnet und schliesst. Dabei ist ein Bügel erkennbar, der fixiert um ein Schwenklager dreht. Dieser Bügel ist an einem Ende über eine Stange mit dem Verschlussdeckel und an dem anderen Ende jenseits des Schwenklagers über eine Schraubenfeder mit einem gehäusefesten Baulement verbunden. Eine Veränderung der Spannung des Bügels ist nicht vorgesehen. Damit offenbart die EP 1 921 394 A1 eine Vorrichtung gemäß dem Oberbegriff von Anspruch 1.The EP 1 921 394 A1 relates to a wall box with a ventilation opening on a guide tube and a closure cover arranged at the end of the guide tube and movable between a closed position and an open position, the closure cover being driven automatically against a restoring force, driven by the pressure difference between the air pressure in the guide tube and the external ambient air opens and closes. A bracket can be seen, which rotates around a swivel bearing. This bracket is connected at one end via a rod to the cover and at the other end beyond the pivot bearing via a coil spring to a structural element fixed to the housing. A change in the tension of the bracket is not intended. With that the EP 1 921 394 A1 a device according to the preamble of claim 1.

Aufgabetask

Aufgabe der vorliegenden Erfindung ist es, eine o.g. Vorrichtung zu entwickeln, deren Einstellung auf einen sich verändernden Luftstrom wesentlich verbessert ist, bei der vor allem die Feinfühligkeit des Ansprechverhaltens wesentlich erhöht ist.The object of the present invention is to develop an above-mentioned device, the adjustment of which to a changing air flow significantly improves is, in particular, the sensitivity of the response is significantly increased.

Lösung der AufgabeSolution of the task

Zur Lösung der Aufgabe führen die Merkmale des kennzeichneden Teils von Anspruch 1. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen definiert.The features of the characterizing part of claim 1 lead to the achievement of the object. Preferred embodiments are defined in the dependent claims.

Diese erfindungsgemässe Anordnung hat den grossen Vorteil, dass die Einstellung auf mehrere Arten erfolgen kann, die in günstiger Weise aufeinander abgestimmt werden können. Eine Einstellung übernimmt der Kraftspeicher. Dieser kann z.B. ein Gummizug od. dgl. sein, bevorzugt wird wohl eine Schraubenfeder. Dieser Kraftspeicher gewährleistet, dass der Bügel immer wieder in seine gewünschte Ausgangslage zurückgebracht wird bzw. einem sich ändernden Luftstrom und damit einer Kraft, die auf das sich im Kanal bewegende Element einwirkt, eine Gegenkraft entgegensetzt wird. Je höher die auf das sich im Kanal bewegende Element wirkende Kraft ist, umso grösser sollte auch die entgegenwirkende Kraft durch den Kraftspeicher sein. Aus diesem Grunde ist die Spannung des Kraftspeichers einstellbar. Dazu ist der Kraftspeicher an seinem einen Ende mit dem Bügel und an seinem anderen Ende mit einem Anlenkelement verbunden. Dieses Anlenkelement kann beliebige ausgestaltet sein, in einem bevorzugten Ausführungsbeispiel handelt es sich um einen Bolzen.This arrangement according to the invention has the great advantage that the setting can be carried out in several ways, which can be coordinated with one another in a favorable manner. The lift mechanism takes over a setting. This can e.g. a rubber band or the like., Preferably a coil spring is preferred. This energy accumulator ensures that the bracket is always returned to its desired starting position or that a changing air flow and thus a force that acts on the element moving in the channel is counteracted by a counterforce. The higher the force acting on the element moving in the channel, the greater the counteracting force due to the energy accumulator. For this reason, the tension of the energy accumulator is adjustable. For this purpose, the energy accumulator is connected at one end to the bracket and at the other end to an articulation element. This articulation element can be designed in any way, in a preferred exemplary embodiment it is a bolt.

Auch der Begriff der Aufspannplatte ist sehr weit zu sehen. Darunter sind alle Halterungen zu verstehen, welche die Stelleinrichtung bzw. Teile dieser Stelleinrichtung gegenüber dem Kanal bzw. gegenüber dem sich in dem Kanal bewegenden Element festlegen.The concept of the platen can also be seen very far. This is to be understood to mean all mounts which fix the actuating device or parts of this actuating device with respect to the channel or with respect to the element moving in the channel.

Die Einstellung des Kraftspeichers könnte nun der Einfachheit halber dadurch geschehen, dass der Anlenkbolzen auf der Aufspannplatte ortsveränderbar angeordnet ist. Hier bietet sich beispielsweise ein entsprechender Schieber an, der entlang der Aufspannplatte verschoben werden kann. Auch für das Verschieben des Schiebers sind viele Möglichkeiten denkbar, die von der vorliegenden Erfindung erfasst sein sollen.For the sake of simplicity, the setting of the energy accumulator could now be done by arranging the pivot pin on the clamping plate so that it can be moved. Here, for example, there is a corresponding slide, which can be moved along the platen. Many possibilities are also conceivable for moving the slide, which should be covered by the present invention.

In einem verbesserten Ausführungsbeispiel ist aber ein Exzenter angeordnet, der den Bügel etwa mittig angreift. Der Bügel liegt auf diesem Exzenter exzentrisch an, so dass der Bügel bei Drehung des Exzenter geschwenkt werden kann und damit die Spannung des Kraftspeichers beeinflusst wird. Dies ist eine sehr elegante Lösung, da im Gegensatz zur Lageveränderung eines Schiebers das Drehen des Exzenters von aussen auf einfache Art und Weise erfolgen kann. In diesem letzt genannten Fall ist der Schieber eigentlich weniger zu einer Veränderung der Spannung des Kraftspeichers gedacht, sondern zu einer insgesamten Lageveränderung der Stelleinrichtung für den Bügel gegenüber der Drehachse des sich in dem Kanal bewegenden Elements.In an improved embodiment, however, an eccentric is arranged, which engages the bracket approximately in the middle. The bracket rests eccentrically on this eccentric, so that the bracket can be pivoted when the eccentric is rotated, thus influencing the tension of the energy accumulator. This is a very elegant solution because, in contrast to changing the position of a slide, the eccentric can be turned from the outside in a simple manner. In the latter case, the slide is actually less intended to change the tension of the energy accumulator, but rather to change the overall position of the actuating device for the bracket relative to the axis of rotation of the element moving in the channel.

Wenn in der vorliegenden Erfindung von Exzenter gesprochen wird, so sollen hier alle Möglichkeiten erfasst sein, die gewährleisten, dass der Bügel mehr oder weniger gegenüber seiner mittigen Abstützung schwenkt.If the present invention speaks of eccentrics, then all possibilities are to be covered here which ensure that the bracket swings more or less with respect to its central support.

Auf der anderen Seite der Verbindung mit dem Kraftspeicher ist der Bügel über eine Schubstange mit einem Rad verbunden, das wiederum dem sich in dem Kanal bewegenden Element zugeordnet ist. In der Regel, aber nicht ausschliesslich, handelt es sich bei dem sich in dem Kanal bewegenden Element um eine Klappe, welche im Öffnungsquerschnitt den Kanal mehr oder weniger verschliesst. Meist dreht diese Klappe um eine Drehachse. In diesem Fall ist das Rad der Drehachse aufgesetzt, so dass über das Rad und die Schubstange eine Zug- bzw. Druckkraft auf den Bügel aufgebracht wird. Durch dieses Rad wird aber auch eine Grundeinstellung des sich in dem Kanal bewegenden Elements durchgeführt. Hierzu ist dem Rad ein weiteres Drehelement zugeordnet, welches in einem bevorzugten Ausführungsbeispiel mit einer entsprechenden Zahnung in eine entsprechende Gegenzahnung in oder an dem Rad angreift. Über dieses Drehelement wird eine Grundeinstellung des Rades und damit der Klappe erzeugt.On the other side of the connection to the energy accumulator, the bracket is connected via a push rod to a wheel, which in turn is assigned to the element moving in the channel. As a rule, but not exclusively, the element moving in the channel is a flap which more or less closes the channel in the opening cross section. This flap usually turns around an axis of rotation. In this case, the wheel of the axis of rotation is attached so that a tensile or compressive force is applied to the bracket via the wheel and the push rod. This wheel also carries out a basic setting of the element moving in the channel. For this purpose, the wheel is assigned a further rotary element which, in a preferred exemplary embodiment, engages with a corresponding toothing in a corresponding counter toothing in or on the wheel. About this rotating element Basic setting of the wheel and thus the flap generated.

FigurenbeschreibungFigure description

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in ihrer einzigen Figur eine perspektivische Ansicht einer erfindungsgemässen Vorrichtung zum Regeln einer Durchströmung eines Kanals 1 mit einem Fluid. Die Regelung dieser Durchströmung übernimmt eine Klappe 2, die in dem Kanal 1 angeordnet ist und um eine Drehachse 3 drehen kann.Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; in its single figure, this shows a perspective view of a device according to the invention for regulating a flow through a channel 1 with a fluid. This flow is regulated by a flap 2, which is arranged in the channel 1 and can rotate about an axis of rotation 3.

Einem Gewinde 4 dieser Drehachse 3 ist ein Rad 5 aufgesetzt, welches mit einem Drehelement 6 in Wirkverbindung steht. Hierzu besitzt das Drehelement 6 eine Zahnung 7, die, in der Zeichnung nicht näher gezeigt, mit einer entsprechenden, dem Rad 5 zugeordneten Zahnung in Eingriff steht. Das Drehelement 6 und die Verbindung zum Rad 5 ist so ausgelegt, dass das Rad 5 in einem gewissen Winkelbereich um die Drehachse 3 gedreht werden kann.A thread 5 is placed on a thread 4 of this axis of rotation 3 and is operatively connected to a rotating element 6. For this purpose, the rotating element 6 has a toothing 7, which, not shown in the drawing, is in engagement with a corresponding toothing assigned to the wheel 5. The rotating element 6 and the connection to the wheel 5 is designed such that the wheel 5 can be rotated about the axis of rotation 3 in a certain angular range.

Das Drehelement 6 selbst sitzt auf einer Aufspannplatte 8 auf, die wiederum über entsprechende Verbindungselement 9 mit dem Kanal 1 verbunden ist. Im vorliegenden Ausführungsbeispiel ist das Drehelement 6 als ein Kreissegment ausgebildet, welches um eine Drehachse 10 drehen kann. Zum Zwecke der besseren Montage kann es in gewissem Umfang auf der Aufspannplatte 8 verschiebbar angeordnet sein. Dies ist aber für die Erfindung von untergeordneter Bedeutung.The rotating element 6 itself is seated on a clamping plate 8, which in turn is connected to the channel 1 via corresponding connecting element 9. In the present exemplary embodiment, the rotating element 6 is designed as a circular segment which can rotate about an axis of rotation 10. For the purpose of better assembly, it can be arranged to a certain extent on the platen 8. However, this is of minor importance for the invention.

Das Rad 5 wiederum ist mit einem Bügel 11 an dessen einen Ende verbunden. Zur Verbindung ist eine Schubstange 12 vorgesehen, die im vorliegenden Ausführungsbeispiel S-förmig gekrümmt ist und mit ihren jeweiligen gekrümmten Enden 13.1 und 13.2 ein exzentrisch angeordnete Bohrung 14 in dem Rad 5 und ein Loch 15 in dem Bügel 11 durchdringt. Dem Loch 15 sind weitere Löcher zugeordnet, wodurch eine Position der Schubstange 12 gegenüber dem Bügel 11 verändert werden kann.The wheel 5 is in turn connected to a bracket 11 at one end. A connecting rod 12 is provided for connection, which is curved in an S-shape in the present exemplary embodiment and with its respective curved ends 13.1 and 13.2 penetrates an eccentrically arranged bore 14 in the wheel 5 and a hole 15 in the bracket 11. Further holes are assigned to the hole 15, whereby a position of the push rod 12 relative to the bracket 11 can be changed.

Etwa mittig stützt sich der Bügel 11 gegen einen Exzenter 16 ab, der wiederum gegenüber einer zungenförmigen Halterung 17 drehbar angeordnet ist. Der Übersichtlichkeit halber ist eine entsprechende Drehachse nicht gezeigt, die Drehrichtung ist lediglich durch den Doppelpfeil 18 angedeutet.Approximately in the middle, the bracket 11 is supported against an eccentric 16, which in turn is rotatably arranged with respect to a tongue-shaped holder 17. For the sake of clarity, a corresponding axis of rotation is not shown, the direction of rotation is only indicated by the double arrow 18.

Der Bügel 11 stützt sich an dem Exzenter 16 so ab, dass er quasi um den Exzenter in einem gewissen Umfang schwenken kann. Dies soll durch die Pfeile 19.1 und 19.2 dargestellt sein.The bracket 11 is supported on the eccentric 16 so that it can pivot to a certain extent, so to speak, about the eccentric. This should be shown by the arrows 19.1 and 19.2.

Die Halterung 17 ist mit einem Schieber 20 verbunden, welcher auf der Aufspannplatte 8 gleitbar angeordnet ist. Geführt wird der Schieber 20 dabei durch entsprechende Bolzen 21.1 und 21.2, die in ein Langloch 22 in der Aufspannplatte 8 eingreifen.The holder 17 is connected to a slide 20 which is slidably arranged on the platen 8. The slide 20 is guided by corresponding bolts 21.1 and 21.2 which engage in an elongated hole 22 in the clamping plate 8.

Von dem Schieber 20 ragt auch ein Bolzen 23 auf, der ein Anlenkelement für einen Kraftspeicher 24 darstellt. Dieser Kraftspeicher 24 kann eine Schraubenfeder sein. Er ist einerseits mit dem Bolzen 23 und andererseits mit einem weiteren Ende 25 des Bügels 11 verbunden.A pin 23 also projects from the slide 20 and represents a link element for an energy accumulator 24. This energy accumulator 24 can be a coil spring. It is connected on the one hand to the bolt 23 and on the other hand to a further end 25 of the bracket 11.

Die Funktionsweise der vorliegenden Erfindung ist folgende:
Zur anfänglichen Einstellung der Öffnungslage der Klappe 2 in dem Kanal 1 wird über das Drehelement 6 das Rad 5 bewegt. Hierdurch kann ein vom Kunden gewünschter Volumenstrom oder ein werksseitig vorgegebener Referenzvolumenstrom eingestellt werden.The operation of the present invention is as follows:
For the initial setting of the opening position of the flap 2 in the channel 1, the wheel 5 is moved via the rotary element 6. In this way, a volume flow desired by the customer or a reference volume flow specified in the factory can be set.

Um aber seiner Aufgabe gerecht zu werden, nämlich in einem komplexen Rohrleitungssystem eine selbsttätige Regelung der Luftmengenverteilung vorzunehmen, kann diese Einstellung nicht fixiert sein, sondern es muss die Möglichkeit bestehen, dass je nach Luftmenge das Rad 5 um die Drehachse 3 drehbar ist, damit die Klappe 2 mehr oder weniger den Querschnitt des Rohrs 1 verschliessen kann. Hierzu sind Regelungselemente vorgesehen. Dazu gehört vor allem der Bügel 11, der einerseits über die Schubstange 12 in seinem Abstand zum Rad 5 relativ fixiert ist. Dieser Abstand kann allerdings durch Einsetzen des Schubstange 12 in die unterschiedlich positionierten Löcher 15 am Ende des Bügels 11 verändert werden.However, in order to fulfill its task, namely to automatically regulate the air volume distribution in a complex piping system, this setting cannot be fixed, but there must be the possibility that, depending on the air volume, the wheel 5 can be rotated about the axis of rotation 3 so that the Flap 2 can more or less close the cross section of the tube 1. Control elements are provided for this. That is part of it especially the bracket 11, which on the one hand is relatively fixed in its distance from the wheel 5 via the push rod 12. However, this distance can be changed by inserting the push rod 12 into the differently positioned holes 15 at the end of the bracket 11.

Der Kraftspeicher 24, der den Bügel 11 am anderen Ende angreift, wirkt einem von der Luftströmung auf das Klappenblatt 2 aufgebrachten Druck entgegen. Dabei schwenkt der Bügel 11 um den Exzenter 16, wobei dies sogar mehr ein Vibrieren sein kann.The energy accumulator 24, which engages the bracket 11 at the other end, counteracts a pressure exerted on the flap leaf 2 by the air flow. The bracket 11 pivots about the eccentric 16, which may even be a vibration.

Der Exzenter 16 hat die Aufgabe, wenn er gegenüber der Halterung 17 gedreht wird, den Bügel 11 beispielsweise in Richtung der Pfeile 19.1 und 19.2 zu bewegen bzw. einem entsprechenden Druck des Bügels 11 nachzugeben, wobei der Kraftspeicher 24 in diesem Fall mehr entspannt wird. Damit wird aber auch der Klappe 2 die Möglichkeit gegeben, sich leichter um die Drehachse 3 drehen zu können.The eccentric 16 has the task, when it is rotated relative to the holder 17, to move the bracket 11, for example in the direction of the arrows 19.1 and 19.2, or to give in to a corresponding pressure of the bracket 11, the energy accumulator 24 being more relaxed in this case. But this also gives the flap 2 the possibility of being able to rotate more easily about the axis of rotation 3.

Insgesamt kann die Anordnung aus Exzenter, Bügel, Halterung, Kraftspeicher 24 und Bolzen 23 gegenüber der Drehachse 3 der Klappe 2 durch Verschieben des Schiebers 20 verstellt werden. Dies verbessert nochmals die Feinfühligkeit des Ansprechverhaltens der Klappe 2 auf einen sich ändernden Luftstrom.

This further improves the sensitivity of the response of the flap 2 to a changing air flow. <b> List of reference symbols </b> 1 channel 34 67 2nd flap 35 68 3rd Axis of rotation 36 69 4th thread 37 70 5 wheel 38 71 6 Rotating element 39 72 7 Perforation 40 73 8th Clamping plate 41 74 9 Fasteners 42 75 10th Axis of rotation 43 76 11 hanger 44 77 12 Push rod 45 78 13 The End 46 79 14 drilling 47 15 hole 48 16 eccentric 49 17th bracket 50 18th Direction of rotation 51 19th arrow 52 20th Slider 53 21 bolt 54 22 Long hole 55 23 bolt 56 24th Lift mechanism 57 25th The End 58 26 59 27th 60 28 61 29 62 30th 63 31 64 32 65 33 66
