Ein derartiges Thermostatventil ist in der DE 27 13 467 A1 offenbart. Hierbei ist das Zwischenstück als zweiteiliges Gehäuse ausgebildet, deren beiden Teile durch gegenseitiges Verdrehen aufeinander zu oder auseinander geschraubt werden können. Dieses Zwischenstück ist wegen seiner Vielzahl der Einzelteile sehr aufwendig in der Konstruktion und in der Fertigung. Durch die Vielzahl der Einzelteile baut dieses Zwischenstück sehr hoch, so daß sich das Thermostatventil in einem starken Maße verlängert.Such a thermostatic valve is in DE 27 13 467 A1 disclosed. Here the intermediate piece is in two parts Housing formed, the two parts by mutual Twisting towards each other or screwed apart can. This adapter is because of its variety Individual parts in the construction and in the very complex Production.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Zwischenstück als eine unrunde, von einem Elektromotor und einem Zwischengetriebe verdrehbare Scheibe ausgeführt ist, auf deren Mantelfläche die Stößel aufliegen und die schwimmend derart gelagert ist, daß sie eine Bewegung in Achsrichtung der Stößel ausführen kann.This object is achieved in that the Intermediate piece as a non-circular, by an electric motor and an intermediate gear rotatable disc is executed, the plungers rest on the lateral surface and the is floating so that it moves in Axial direction of the ram can run.

Diese elektrisch betätigbare Veränderung der Sollwerteinstellung hat noch den Vorteil, daß die Energiezufuhr nur während des Verstellvorganges erforderlich ist, während in der übrigen Zeit die neue Stellung der Stößel mechanisch arretiert ist.This electric Actuable change of the setpoint setting still has the  Advantage that the energy supply only during the Adjustment is required while in the rest Time the new position of the plunger is mechanically locked.

Bei einer vorteilhaften Ausbildung ist die Scheibe so gestaltet, daß sich ihr Durchmesser über den Bogen von 90° stetig ändert. Damit wird erreicht, daß sich die Längenänderung des Zwischenstücks über jedes Grad der Scheibenverstellung gleichmäßig ändert.In an advantageous embodiment, the disc is like this designed that their diameter over the arc of 90 ° constantly changing. This ensures that the Change in length of the adapter over each degree of Disc adjustment changes evenly.

Außerdem ist es vorteilhaft, daß das Zwischenstück in einem hülsenförmigen Stutzen eingesetzt ist, der mit Überwurfmuttern auf der einen Seite am Thermostatkopf und auf der anderen Seite an dem Ventilkörper oder Ventilgehäuse befestigt ist.It is also advantageous that the intermediate piece in one sleeve-shaped nozzle is used, with Union nuts on one side of the thermostatic head and on the other hand on the valve body or valve housing is attached.

Die Zeichnung veranschaulicht ein vorteilhaftes Ausführungsbeispiel der Erfindung.The drawing illustrates an advantageous Embodiment of the invention.

Der Thermostatkopf (1) und das Ventil (3) sind über ein Zwischenteil (2) miteinander verbunden. Das Ventil (3) besteht aus dem Ventilgehäuse (4) und dem darin eingeschraubten Ventilkörper (5). Der Ventilkörper (5) wird von einem Stößel (6) durchsetzt, an dessen unterem Ende der Ventilteller (7) angesetzt ist und auf dessen oberes Ende der Stößel (8) des Thermostatkopfes (1) unter Zwischenschaltung des Zwischenstücks (10) einwirkt. Der Thermostatkopf (1) weist einen Thermostaten (11) auf, der aus einer mit Flüssigkeit oder Wachs gefüllten Faltenbalgdose besteht. In dem Faltenbalg (12) ist der Stößel (8) eingelassen, der je nach Höhe der Raumtemperatur mehr oder weniger weit aus dem Faltenbalg (12) herausragt. Der Thermostat (11) ist in ein geschlitztes Gehäuse (13) eingesetzt, das mit einem Rohrstutzen (14) in ein kranzförmiges Unterteil (15) eingeschraubt ist. Durch Betätigung dieses Schraubgewindes ändert sich der Abstand des Thermostaten (11) zum Stößel (6) des Ventils (3). Als Handhabe zum Verdrehen des Gehäuses (13) ist über dieses eine ebenfalls geschlitzte Kappe (16) gestülpt, die verdrehsicher mit dem Gehäuse (13) verbunden ist. Durch Verdrehen der Einstellkappe (16) wird die Soll-Stellung des Thermostatstößels (8) für eine bestimmte Raumtemperatur vorgegeben.The thermostatic head ( 1 ) and the valve ( 3 ) are connected to each other via an intermediate part ( 2 ). The valve ( 3 ) consists of the valve housing ( 4 ) and the valve body ( 5 ) screwed into it. The valve body ( 5 ) is penetrated by a plunger ( 6 ), at the lower end of which the valve disk ( 7 ) is attached and on the upper end of which the plunger ( 8 ) of the thermostatic head ( 1 ) acts with the interposition of the intermediate piece ( 10 ). The thermostatic head ( 1 ) has a thermostat ( 11 ) which consists of a bellows can filled with liquid or wax. The plunger ( 8 ) is embedded in the bellows ( 12 ) and, depending on the room temperature, protrudes more or less far from the bellows ( 12 ). The thermostat ( 11 ) is inserted into a slotted housing ( 13 ) which is screwed into a ring-shaped lower part ( 15 ) with a pipe socket ( 14 ). By actuating this screw thread, the distance between the thermostat ( 11 ) and the tappet ( 6 ) of the valve ( 3 ) changes. As a handle for rotating the housing ( 13 ), a likewise slotted cap ( 16 ) is placed over it, which is connected to the housing ( 13 ) in a manner that prevents it from rotating. The set position of the thermostatic tappet ( 8 ) is specified for a specific room temperature by turning the adjusting cap ( 16 ).

Zwischen Thermostatkopf (1) und Ventil (3) ist ein längenveränderbares Zwischenstück (10) eingesetzt. Das Zwischenstück (10) ist im wesentlichen als eine ovale Scheibe ausgebildet, deren senkrecht aufeinanderstehende Achsen unterschiedlich lang sind. Die Scheibe wird von einem Drehkreuz angetrieben, das wiederum über ein Getriebe (30) von dem Elektromotor (31) angetrieben wird. Die das Zwischenstück (10) bildende Scheibe ist zwischen den Stößeln (6) und (8) schwimmend gelagert. Dieses ist erforderlich, damit das Zwischenstück (10) zusammen mit den Stößeln (6) und (8) eine Bewegung in Achsrichtung der Stößel durchführen kann. Beim Verdrehen der Scheibe (10) um 90° wird je nach ihrer Ausgangslage der Abstand zwischen den Stößeln (6) und (8) entweder vergrößert oder verkleinert. Die Ansteuerung des Motors (31) erfolgt über eine nicht dargestellte Schaltuhr, die mit einem Raumthermostaten gekoppelt sein kann, der ein Unterschreiten einer Mindesttemperatur verhindert.A length-adjustable intermediate piece ( 10 ) is inserted between the thermostatic head ( 1 ) and the valve ( 3 ). The intermediate piece ( 10 ) is essentially designed as an oval disk, the axes of which are perpendicular to one another and have different lengths. The disc is driven by a turnstile, which in turn is driven by the electric motor ( 31 ) via a gear ( 30 ). The disc forming the intermediate piece ( 10 ) is floating between the plungers ( 6 ) and ( 8 ). This is necessary so that the intermediate piece ( 10 ) together with the plungers ( 6 ) and ( 8 ) can move in the axial direction of the plungers. When the disc ( 10 ) is rotated by 90 °, the distance between the plungers ( 6 ) and ( 8 ) is either increased or decreased, depending on its starting position. The motor ( 31 ) is controlled via a time switch (not shown) which can be coupled to a room thermostat which prevents the temperature from falling below a minimum.
