Abstract

The invention relates to a volume flow regulator for air-conditioning and ventilation systems with a flap (3) which is pivotable in a flow duct and the pivot shaft (2) of which has a lever arm (11), on which a spring (5) engages in an articulated manner. In order to indicate a mechanically automatic volume flow regulator, in which the spring can be adapted to the regulating operation by simple adjustment, the spring is to be a leaf spring, one end of which is connected to the lever and the other end of which is fastened on a cam plate in such a manner that, on displacement of the cam plate (8) about a point of rotation (7), the leaf spring is carried along by the cam plate and rolls off on the cam and that an arrangement for fixing the cam plate is provided. <IMAGE>

Description

Die Erfindung betrifft einen Volumenstromregler für Klima- und Lüftungsanlagen mit einer in einem Strömungskanal schwenkbaren Klappe, deren Schwenkwelle einen Hebelarm aufweist, an dem gelenkig eine Feder angreift.The invention relates to a volume flow controller for air conditioning and ventilation systems with a flap pivotable in a flow channel, the pivot shaft of which has a lever arm on which a spring articulates.

Derartige Volumenstromregler sind in verschiedenen Ausführungen bekannt. Sie arbeiten mechanisch selbststätig, weil das strömungsbedingte Klappendrehmoment durch die Feder kompensiert wird. Bei Anderung der Strömungsverhältnisse ändert sich auch die Schwenkstellung der Klappe. Voraussetzung dafür ist allerdings, daß die Feder für jeden Regler speziell kalibriert werden muß.Such volume flow controllers are known in various designs. They work mechanically automatically because the flow-related flap torque is compensated by the spring. When the flow conditions change, the swivel position of the flap also changes. However, the prerequisite for this is that the spring must be specially calibrated for each controller.

Aufgabe der Erfindung ist es, einen mechanisch selbststätigen Volumenstromregler anzugeben, bei dem die Feder durch einfache Einstellung dem Regelvorgang angepaßt werden kann.The object of the invention is to provide a mechanically automatic volume flow controller in which the spring can be adapted to the control process by simple adjustment.

Diese Aufgabe wird dadurch gelöst, daß die Feder eine Blattfeder ist, deren eines Ende mit dem Hebel verbunden ist und deren anderes Ende so an einer Kurvenscheibe befestigt ist, daß bei Verstellung der Kurvenscheibe um einen Drehpunkt die Blattfeder von der Kurvenscheibe mitgenommen wird und auf der Kurve abrollt, und daß eine Einrichtung zum Fixieren der Kurvenscheibe vorgesehen ist. Zur Anpassung der Blattfeder an den jeweiligen Regler genügt es, die Kurvenscheibe um ihren Drehpunkt zu verdrehen, bis die Blattfeder die gewünschte Federvorspannung erreicht hat. Dabei ändern sich im allgemeinen auch die Federkonstante und die Kraftangriffsrichtung. Nach Verstellung der Kurvenscheibe bis auf die gewünschten Sollwerte wird diese Stellung der Kurvenscheibe fixiert.This object is achieved in that the spring is a leaf spring, one end of which is connected to the lever and the other end is thus fastened to a cam disk is that when the cam disk is adjusted about a pivot point, the leaf spring is carried along by the cam disk and rolls on the curve, and that a device is provided for fixing the cam disk. To adapt the leaf spring to the respective controller, it is sufficient to turn the cam disc around its pivot point until the leaf spring has reached the desired spring preload. In general, the spring constant and the direction of force application also change. After adjusting the cam disc to the desired setpoints, this position of the cam disc is fixed.

Es kann zweckmäßig sein, zur Verbindung des Hebels mit dem zugeordneten Ende der Blattfeder eine Verbindungsstange oder ein Verbindungsseil vorzusehen. Dadurch werden die Möglichkeiten der konstruktiven Gestaltung erweitert.It may be expedient to provide a connecting rod or a connecting cable for connecting the lever to the associated end of the leaf spring. This extends the possibilities of constructive design.

Ein bevorzugte Ausführung der Erfindung ist gekennzeichnet durch eine Anordnung derart, daß die entspannte Blattfeder sich im wesentlichen orthogonal zum Strömungskanal erstreckt.A preferred embodiment of the invention is characterized by an arrangement such that the relaxed leaf spring extends essentially orthogonally to the flow channel.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; die einzige Figur zeigt schematisch die Ansicht eines Volumenstromreglers.In the following an embodiment of the invention shown in the drawing is explained; the only figure shows schematically the view of a volume flow controller.

In der Figur erkennt man einen Strömungskanal 1 mit einer darin auf einer Schwenkwelle 2 angeordneten Klappe 3, die aus ihrer mit gestrichelten Linien wiedergegebenen Grundstellung und der Wirkung von Strömungskräften der Luftströmung 6 und gegen die Wirkung einer Feder 5 in Richtung des Pfeils 4 verschwenkbar ist.In the figure, a flow channel 1 can be seen with a flap 3 arranged therein on a swivel shaft 2, which, based on its basic position shown in dashed lines and the effect of flow forces of the air flow 6 and against the action of a spring 5 in the direction the arrow 4 is pivotable.

Am Strömungskanal 1 ist um einen Drehpunkt 7 verschwenkbar eine Kurvenscheibe 8 gelagert, die mit einer nicht dargestellten Richtung zum Fixieren in unterschiedlichen Schwenkstellungen festgelegt werden kann. An dem in der Figur unteren Ende einer von der Kurvenscheibe 8 gebildeten Kurve 9 ist die Feder 5 befestigt, die als Blattfeder ausgebildet ist. Das andere Ende der Feder 5 ist gelenkig an eine Verbindungsstange 10 oder ein Verbindungsseil mit einem Hebel 11 verbunden, der auf der Schwenkwelle 2 der Klappe 3 sitzt.A cam disk 8 is mounted on the flow channel 1 so as to be pivotable about a pivot point 7 and can be fixed with a direction (not shown) for fixing in different pivot positions. At the lower end in the figure of a curve 9 formed by the cam 8, the spring 5 is attached, which is designed as a leaf spring. The other end of the spring 5 is articulated to a connecting rod 10 or a connecting cable with a lever 11 which sits on the pivot shaft 2 of the flap 3.

Mit ausgezogenen Linien ist die entspannte Feder 5 wiedergegeben, die sich dann im wesentlichen orthogonal zum Strömungskanal 1 bzw. zur Strömungsrichtung erstreckt. Mit gestrichelten Linien ist eine Funktionsstellung wiedergegeben, bei der die Kurvenscheibe 8 um einen bestimmten Winkel in Richtung des Pfeils 12 verschwenkt worden ist. Beim Verschwenken rollt die Blattfeder 5 auf der Kurve 9 der Kurvenscheibe 8 ab, wobei ihr an die Verbindungsstange 10 angeschlossenes Ende eine Durchbiegung erfährt. Dabei ändern sich die Federkonstante, die Federvorspannung und die Kraftangriffsrichtung am Hebel 11.The relaxed spring 5 is shown with solid lines, which then extends essentially orthogonally to the flow channel 1 or to the flow direction. A functional position is shown with dashed lines, in which the cam plate 8 has been pivoted by a certain angle in the direction of the arrow 12. When pivoting, the leaf spring 5 rolls on the curve 9 of the cam 8, whereby its end connected to the connecting rod 10 experiences a deflection. The spring constant, the spring preload and the direction of force application on the lever 11 change.

Sollen die Eigenschaften des Reglers verändert werden, dann genügt es, die Kurvenscheibe 8 zu lösen und in eine andere Position zu verstellen.If the properties of the controller are to be changed, it is sufficient to loosen the cam disc 8 and to adjust it to a different position.
