Description

Die vorliegende Erfindung betrifft einen Warmwasserspeicher mit einem Innenbehälter, der zwei gegenüberliegende Längsseitenwände und zwei mit diesen verbundene Querseitenwände aufweist sowie eine Behälterdecke, wobei entweder zwei gegenüberliegende Längsseitenwände oder zwei gegenüberliegende Querseitenwände vorzugsweise in einem in Bezug auf die Höhe des Behälters und die Breite des Behälters mittleren Bereich nach innen zur Behältermitte hin eingezogen sind, wobei der zur Behältermitte hin eingezogene Bereich der Längsseitenwände oder Querseitenwände beidseitig jeweils etwa die Form eines Trichters oder Konus hat und jeweils die Trichterböden der beiden Trichter in der Behältermitte aneinanderliegen und sich flächig gegeneinander abstützen.The present invention relates to a hot water tank with an inner container, which has two opposite longitudinal side walls and two transverse side walls connected to them, and a container ceiling, wherein either two opposite longitudinal side walls or two opposite transverse side walls, preferably in one in relation to the height of the container and the width of the container The area drawn in toward the center of the container is drawn in, the area of the longitudinal side walls or transverse side walls drawn in toward the center of the container having the shape of a funnel or cone on both sides and the funnel bottoms of the two funnels abutting each other in the center of the container and being supported against one another in a planar manner.

Aus dem Stand der Technik sind Warmwasserspeicher mit Innenbehältern der eingangs genannten Gattung bekannt geworden, z. B. aus der AT 386 069 (B). Die Maßnahme, die Seitenwände des Behälters zur Behältermitte hin einzuziehen, so daß sie sich flächig gegeneinander abstützen dient dazu, den Innenbehälter des Warmwasserspeichers zu stabilisieren. Bei einem Warmwasserspeicher der genannten Art sind verschiedene funktionelle Teile notwendig, die in oder am Warmwasserspeicher montiert werden müssen, beispielsweise die Regelgruppe mit Stelleinrichtung für die Einstellung der gewünschten Aufheiztemperatur.From the prior art, hot water tanks with inner containers of the type mentioned are known, for. B. from AT 386 069 (B). The measure of drawing in the side walls of the container towards the center of the container so that they are supported against each other over a large area serves to stabilize the inner container of the hot water tank. In the case of a hot water tank of the type mentioned, various functional parts are necessary which have to be mounted in or on the hot water tank, for example the control group with an adjusting device for setting the desired heating temperature.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Warmwasserspeicher mit einem Innenbehälter der eingangs genannten Gattung zu schaffen, bei dem die genannten Baugruppen für die Regelung und Einstellung der gewünschten Temperatur einfach montierbar sind und platzsparend untergebracht sind.The present invention has for its object to provide a hot water tank with an inner container of the type mentioned, in which the modules for the regulation and setting of the desired temperature are easy to assemble and are housed in a space-saving manner.

Die Lösung dieser Aufgabe liefert ein Warmwasserspeicher mit einem Innenbehälter der eingangs genannten Art mit den kennzeichnenden Merkmalen des Hauptanspruchs. Die erfindungsgemäße Lösung macht sich die Tatsache zu nutze, daß aus Stabilitätsgründen der Innenbehälter etwa in der Behältermitte einen eingezogenen Bereich in den Behälterseitenwänden aufweist. Dadurch wird ein trichterförmiger oder kegelförmiger Freiraum geschaffen, in dem sich eine für den Warmwasserspeicher notwendige Baugruppe unterbringen läßt. Weiterhin schafft die Tatsache, daß die Trichterböden der beiden Trichter des Innenbehälters sich gegeneinander abstützen und im Bereich einer gewissen Fläche aneinanderliegen die Möglichkeit, dort eine Durchgangsbohrung unterzubringen, die dann ein Befestigungselement aufnehmen kann und somit eine Befestigungmöglichkeit für den Anbau notwendiger Montageteile schafft. Im Rahmen der vorliegenden Erfindung sind diese Montageteile vorzugsweise solche, die mit einer elektrischen/elektronischen Baugruppe für die Regelung und Einstellung der gewünschten Aufheiztemperatur im Zusammenhang stehen. Es sind aber auch andere Möglichkeiten zur Nutzung des durch die trichterförmige Ausbildung des Innenbehälters geschaffenen Freiraums möglich und die vorliegende Erfindung ist nicht auf die vorgenannte bevorzugte elektrische/elektronische Baugruppe beschränkt.The solution to this problem is provided by a hot water tank with an inner container of the type mentioned with the characterizing features of the main claim. The solution according to the invention takes advantage of the fact that, for reasons of stability, the inner container approximately in the Container center has a retracted area in the container side walls. This creates a funnel-shaped or conical free space in which an assembly necessary for the hot water tank can be accommodated. Furthermore, the fact that the funnel bottoms of the two funnels of the inner container are supported against one another and lie against one another in the area of a certain area makes it possible to accommodate a through hole there, which can then accommodate a fastening element and thus creates a fastening possibility for the installation of necessary assembly parts. In the context of the present invention, these assembly parts are preferably those which are associated with an electrical / electronic assembly for regulating and setting the desired heating temperature. However, there are also other possibilities for using the free space created by the funnel-shaped design of the inner container, and the present invention is not restricted to the aforementioned preferred electrical / electronic assembly.

In einem der beiden Trichter des Innenbehälters kann man vorzugsweise eine Art kegelförmiges Bauelement einsetzen und über ein Befestigungselement, das von der Durchgangsbohrung aufgenommen wird, am Trichterboden befestigen. An diesem kegelförmigen Bauelement werden dann wiederum weitere für die Funktion des Warmwasserspeichers notwendige Bauelemente befestigt. Man benötigt so nur eine Bohrung des Innenbehälters, nämlich die Durchgangsbohrung, die sich dort befindet, wo die Trichterböden aneinanderliegen, denn verständlicherweise kann man für den Anbau weiterer Bauelemente nicht ohne weiteres in die Wandung des im bestimmungsgemäßen Gebrauch mit Wasser gefüllten Innenbehälters bohren, da sich dadurch Dichtigkeitsprobleme ergäben. Deshalb ist es vorteilhaft, das kegelförmige Bauelement zu verwenden, das so ausgebildet ist, daß es eine Anbringung weiterer Bauteile ermöglicht und das für diese Bauteile einen Aufnahmeraum bietet, so daß die Bauelemente nicht zu weit über die äußere Begrenzung des Innenbehälters nach außen ragen und dadurch die Baugröße des gesamten Warmwasserspeichers so gering wie möglich gehalten wird. Warmwasserspeicher dieser Art weisen üblicherweise um den Innenbehälter herum eine Isolierung auf und haben außerdem einen Außenbehälter, der dazu dient die Baugruppen und den Innenbehälter nach außen hin zu schützen und zu verkleiden. Die minimale Baugröße des gesamten Warmwasserspeichers wird durch das Aufnahmevolumen des Innenbehälters und die zur Wärmedämmung notwendige Schichtdicke der Isolierung vorgegeben und in diesem Bauvolumen sollten möglichst alle außerdem notwendigen Baugruppen des Warmwasserspeichers Platz haben. Bei einem erfindungsgemäßen Warmwasserspeicher wird die Baugröße unter diesem Gesichtspunkt optimiert.In one of the two funnels of the inner container, a type of conical component can preferably be used and fastened to the funnel bottom by means of a fastening element which is received by the through hole. Further components necessary for the function of the hot water tank are then attached to this conical component. You only need one hole in the inner container, namely the through-hole, which is located where the funnel bottoms lie against each other, because it is understandable that it is not easy to drill into the wall of the inner container filled with water as intended for the attachment of additional components because this would result in tightness problems. It is therefore advantageous to use the conical component which is designed in such a way that further components can be attached and which offers a receiving space for these components, so that the components do not extend too far beyond the outer boundary of the inner container protrude outwards and the size of the entire hot water tank is kept as small as possible. Hot water storage tanks of this type usually have insulation around the inner container and also have an outer container which serves to protect and disguise the assemblies and the inner container from the outside. The minimum size of the entire hot water tank is determined by the volume of the inner tank and the layer thickness of the insulation required for thermal insulation, and if possible, all of the hot water tank assemblies that are also required should have space in this volume. In a hot water tank according to the invention, the size is optimized from this point of view.

Gemäß einer bevorzugten konstruktiven Lösung im Rahmen einer Weiterbildung der Erfindung ist vorgesehen, daß für die Befestigung des elektrischen/elektronischen Bauelements und gegebenenfalls weiterer Bauelemente an dem kegelförmigen Bauelement eine auf dieses im äußeren Bereich aufsteckbare Scheibe vorgesehen ist. An dieser Scheibe kann das elektrische/elektronische Bauelement und gegebenenfalls weitere Bauelemente festgelegt werden. Man kann das kegelförmige Bauelement auch dazu benutzen, den Außenbehälter des Warmwasserspeichers am Innenbehälter festzulegen.According to a preferred constructive solution within the scope of a further development of the invention, it is provided that for the fastening of the electrical / electronic component and possibly further components to the conical component, a disc which can be plugged onto the outer region thereof is provided. The electrical / electronic component and, if appropriate, further components can be fixed on this disk. You can also use the cone-shaped component to fix the outer tank of the hot water tank to the inner tank.

Das genannte elektrische/elektronische Bauelement umfaßt vorzugsweise eine Regelung und/ einen Thermostaten. Zur Einstellung der gewünschten Aufheiztemperatur des Wasserspeichers wird vorzugsweise ein drehbares Bedienelement verwendet, das mit dem elektrischen/elektronischen Bauelement in Wirkverbindung steht und das an dem kegelförmigen Bauelement beispielsweise mittels der auf dieses im äußeren Bereich aufsteckbaren Scheibe festlegbar ist.Said electrical / electronic component preferably comprises a control and / or a thermostat. To set the desired heating temperature of the water reservoir, a rotatable control element is preferably used, which is operatively connected to the electrical / electronic component and which can be fixed to the conical component, for example by means of the disc which can be plugged onto the outer region thereof.

Dieses Bedienelement ist natürlich in der Regel an der Außenseite des Außenbehälters angeordnet, während sich die Regelung und der Thermostat auf der Innenseite des Außenbehälters befinden. Das Bedienelement ist vorzugsweise um eine Achse drehbar angeordnet, die der Mittelachse des kegelförmigen Bauelements entspricht. Das kegelförmige Bauelement kann in sehr einfacher Weise z. B. über eine Schraube oder dergleichen die durch die Durchgangsbohrung der beiden aneinanderliegenden Trichterböden greift, am Innenbehälter festgelegt werden. Die Kegelform des kegelförmigen Bauelements hat zum einen den Sinn, daß diese an die Form der Trichter des Innenbehälters angepaßt ist und das kegelförmige Bauelement sich am Innenbehälter abstützt. Zum anderen kann der äußere Umfangsbereich des kegelförmigen Bauelements für das Aufstecken z. B. einer Scheibe genutzt werden. Dies ermöglicht eine Vormontage, nämlich die Regelungsbaugruppe, der Thermostat etc. können auf die Scheibe montiert werden und dann kann die Scheibe einfach auf das kegelförmige Bauelement aufgesteckt werden, so daß die Montage rasch von statten geht. Vorzugsweise ist eine Achse der Regelungsbaugruppe vorhanden, die durch die Scheibe hindurch nach außen ragt, vorzugsweise durch eine Öffnung des Außenbehälters hindurch, so daß nach Aufsetzen des Außenbehälters das Bedienelement z. B. durch angeformte Rastelemente oder dergleichen auf diese Achse der Regelungsbaugruppe einfach aufgesteckt werden kann. Natürlich sind zahlreiche andere Montagemöglichkeiten denkbar, die im Rahmen des erfindungsgemäßen Prinzips liegen, wonach die Trichter des Innenbehälters für die Befestigung von Montageteilen des Warmwasserspeichers genutzt werden.This control element is of course usually arranged on the outside of the outer container, while the control and the thermostat are on the inside of the outer container. The control element is preferred arranged rotatably about an axis which corresponds to the central axis of the conical component. The conical component can in a very simple manner, for. B. via a screw or the like which reaches through the through hole of the two adjacent funnel bottoms, can be fixed on the inner container. The conical shape of the conical component has the meaning that it is adapted to the shape of the funnel of the inner container and the conical component is supported on the inner container. On the other hand, the outer peripheral region of the conical component for plugging z. B. a disc can be used. This enables a pre-assembly, namely the control assembly, the thermostat etc. can be mounted on the disc and then the disc can simply be plugged onto the conical component, so that the assembly is quick. Preferably, there is an axis of the control assembly which protrudes through the pane to the outside, preferably through an opening of the outer container, so that after the outer container has been placed on, the control element, e.g. B. can be simply plugged onto this axis of the control assembly by molded locking elements or the like. Of course, numerous other mounting options are conceivable, which are within the scope of the principle according to the invention, according to which the funnels of the inner container are used for fastening mounting parts of the hot water tank.

Das vorgenannte kegelförmige Bauelement, das in einen der Trichter des Innenbehälters einsetzbar ist, muß keinen durchgehenden Kegelmantel haben, sondern kann z. B. so ausgebildet sein, daß es über den Umfang verteilt angeordnete Stege aufweist, die diesem Bauelement einen in etwa kegelförmigen Umriß geben, wobei mehrere solcher Stege an ihrem einen Ende oder auch an beiden Enden miteinander verbunden sind und zwischen diesen Stegen kleinere oder größere Durchbrechungen vorhanden sind. Beispielsweise kann man ein kegelförmiges Bauelement mit vier solcher Stege verwenden, wobei sich dann die Stege an den Wänden des Trichters des Innenbehälters abstützen. Wenn die Stege im Bereich der Spitze des kegelförmigen Bauelements verbunden sind, befindet sich dort ein ausreichendes Widerlager für ein Befestigungselement für die Anbringung am Trichterboden. Außenseitig kann die Scheibe auf die Enden der Stege aufgesetzt werden. Die der Form des Kegelmantels folgenden Stege können an ihrem äußeren Ende durch einen stabilisierenden Ringsteg miteinander verbunden sein.The aforementioned conical component, which can be used in one of the funnels of the inner container, does not have to have a continuous cone jacket, but can, for. B. be designed such that it has webs distributed over the circumference, which give this component an approximately conical shape, several such webs being connected at one end or also at both ends and smaller or larger openings between these webs available. For example, one can use a conical component with four such webs, the webs then being located on the walls of the Support the funnel of the inner container. If the webs are connected in the region of the tip of the conical component, there is sufficient abutment there for a fastening element for attachment to the funnel bottom. On the outside, the disc can be placed on the ends of the webs. The webs following the shape of the cone shell can be connected to one another at their outer end by a stabilizing ring web.

Nachfolgend wird zunächst auf die Fig. 1 und 2 Bezug genommen. Der Innenbehälter 30 für einen Warmwasserspeicher gemäß der Erfindung hat am Innenbehälter angeformte Kanäle für den Wasserzulauf bzw. Ablauf und zwar im oberen Bereich einen Ablaufkanal 28 für das Warmwasser und daneben angeordnet einen Zulaufkanal 27 für das eintretende Kaltwasser. Dieser Zulaufkanal 27 mündet in einen weiteren Kanal 26, der an dem Behälter 30 entlang geführt ist bis zur Behälterunterseite wo er um 90° Grad umgelenkt ist und dann etwa horizontal in den Innenbehälter 30 mündet. Das Kaltwasser gelangt also dort in den Innenbehälter, erwärmt sich in diesem und verläßt als Warmwasser den Behälter wieder über den oben angeformten Kanal 28.In the following, reference is first made to FIGS. 1 and 2. The inner container 30 for a hot water tank according to the invention has channels formed on the inner container for the water inlet and outlet, specifically in the upper region an outlet channel 28 for the hot water and next to it an inlet channel 27 for the inlet Cold water. This inlet channel 27 opens into a further channel 26, which is guided along the container 30 to the bottom of the container where it is deflected by 90 ° and then opens approximately horizontally into the inner container 30. The cold water thus gets there into the inner container, heats up in it and leaves the container again as warm water via the channel 28 formed above.

Die Grundform des Innenbehälters 30 leitet sich von derjenigen eines Quaders ab und der Innenbehälter 30 hat einen annähernd rechteckigen Außenumriß mit etwas abgerundeten Eckübergangsbereichen 33. Die Behälterform weicht jedoch insofern von einer Quaderform oder Kastenform ab, als die beiden Längsseitenwände 31a, 31b, die durch die beiden Querseitenwände 32a, 32b miteinander verbunden sind, in einem etwa mittigen Bereich eingezogen sind nach innen hin derart, daß sich dort zwei gegenüberliegende Trichter 20a, 20b ergeben, die soweit zur Mitte hinreichen, daß jeweils die Trichterböden 20c aneinanderliegen und sich gegenseitig im Bereich der kreisrunden Berührungsfläche abstützen. Die beiden Trichterböden weisen hier eine Durchgangsbohrung 20d auf, so daß man hier Montageteile befestigen kann, die für bestimmte Funktionen des Warmwasserspeichers benötigt werden, wie hier nachfolgend anhand eines Beispiels erläutert wird. Durch die Ausbildung der beiden Trichter 20a, 20b im mittleren Bereich erhält der Innenbehälter 30 eine verbesserte Steifigkeit und Stabilität. Der Fluß des Wassers aus der unteren Hälfte des Innenraums des Innenbehälters in dessen obere Hälfte geschieht dadurch, daß das Wasser durch die Verbindungsräume 23, 24 strömt, die wie Passagen rechts und links der beiden Trichter 20a, 20b bilden (siehe Fig. 1).The basic shape of the inner container 30 is derived from that of a cuboid and the inner container 30 has an approximately rectangular outer contour with somewhat rounded corner transition areas 33. However, the container shape differs from a cuboid shape or box shape in that the two longitudinal side walls 31a, 31b, which are formed by the The two transverse side walls 32a, 32b are connected to one another, and are drawn inward in an approximately central region in such a way that there are two opposite funnels 20a, 20b, which extend so far towards the center that the funnel bottoms 20c abut each other and mutually in the region of support circular contact surface. The two funnel bottoms here have a through hole 20d, so that here mounting parts can be fastened which are required for certain functions of the hot water tank, as will be explained below using an example. The design of the two funnels 20a, 20b in the central region gives the inner container 30 improved rigidity and stability. The flow of water from the lower half of the interior of the inner container in its upper half occurs in that the water flows through the connecting spaces 23, 24 which, like passages, form the right and left of the two funnels 20a, 20b (see FIG. 1).

Der Innenbehälter 30 hat im unteren Bereich eine Öffnung 42, die an einer Seite außermittig angeordnet ist und einen kreisförmigen Umriß hat. Diese Öffnung 42 dient dazu, eine Heizspirale durch diese Öffnung in den Innenbehälter 30 einzuführen. Dadurch daß man die Heizspirale außermittig in den Innenbehälter 30 einführt, wird eine bessere Zirkulation des Warmwassers im Innenbehälter erreicht.The inner container 30 has an opening 42 in the lower region, which is arranged off-center on one side and has a circular outline. This opening 42 serves to introduce a heating coil through this opening into the inner container 30. Because the heating coil is off-center in introduces the inner container 30, a better circulation of the hot water in the inner container is achieved.

Die Nutzung des Trichters bzw. eines der beiden Trichter 20a bzw. 20b zur Befestigung bestimmter Bauelemente wird anhand der Figuren 2 und 3 deutlich. Fig. 2 zeigt in einer Explosionsdarstellung ein kegelförmiges Bauelement 200, das in seiner äußeren Umrißform an die des Trichters 20b angepaßt ist. Dieses kegelförmige Bauelement 200 weist vier über den Umfang verteilt angeordnete an einer Seite des Bauelements 200 kegelförmig aufeinander zulaufende Stege 200a auf, die an der Außenseite des kegelförmigen Bauelements 200 durch einen Ringsteg 200b miteinander verbunden sind. An der Innenseite des kegelförmigen Bauelements 200, die dem Trichterboden 20c des Innenbehälters zugeordnet ist sind die vier Stege 200a zu einer Art Kegelstumpf 200c verbunden. Dieser Kegelstumpf 200c weist eine Bohrung 200d auf, so daß man einen Treibstift 201 oder ein ähnliches Befestigungselement durch diese Bohrung 200d und die Bohrung 20d im Trichterboden 20c hindurchführen kann, um das kegelförmige Bauelement 200 am Innenbehälter 30 zu befestigen so wie dies in Fig. 3 dargestellt ist.The use of the funnel or one of the two funnels 20a and 20b for fastening certain components can be seen from FIGS. 2 and 3. Fig. 2 shows an exploded view of a conical component 200, which is adapted in its outer contour to that of the funnel 20b. This conical component 200 has four webs 200a, which are distributed around the circumference on one side of the component 200 and which are connected to one another on the outside of the conical component 200 by an annular web 200b. On the inside of the conical component 200, which is assigned to the funnel bottom 20c of the inner container, the four webs 200a are connected to form a truncated cone 200c. This truncated cone 200c has a bore 200d so that a driving pin 201 or a similar fastening element can be passed through this bore 200d and the bore 20d in the funnel base 20c in order to fasten the conical component 200 to the inner container 30, as shown in FIG. 3 is shown.

Es wird nun nachfolgend auf die Fig. 4 und 5 Bezug genommen. Man erkennt hier, daß der Innenbehälter 30 in eine Isolierung 300 eingebettet ist und diese wiederum von einem Außenbehälter 205 umschlossen wird, der den Innenbehälter 30 verkleidet und der eine annähernd quaderförmige Kastenform hat. Man erkennt auch in den Fig. 4 und 5 die Heizspirale 41, die in die Kreisöffnung 42 des Innenbehälters 30 eingeführt ist. Wie man sieht nimmt das kegelförmige Bauelement 200 in seinem Innenraum im äußeren Bereich eine Regelungsbaueinheit 202 mit Thermostat auf, die an der Scheibe 203 an deren Innenseite befestigt ist. Diese Scheibe 203 ist wiederum am Umfang mit Stegen versehen und mit diesen Stegen auf die Stege 200a und den Ringsteg 200b des kegelförmigen Bauelements 200 aufgesetzt und damit an diesem befestigt. Durch eine Bohrung im Außenbehälter 205 ragt eine Befestigungsachse 206, auf die dann wiederum das drehbare Bedienelement 204 aufsteckbar ist, mittels dessen man die gewünschte Aufheiztemperatur durch Einwirkung auf die Regelungsbaueinheit 202 von der Außenseite des Außenbehälters 205 her bei montiertem Warmwasserspeicher einstellen kann. Es werden dann über einen Stromkreis, der hier nicht im einzelnen dargestellt ist die entsprechenden Schaltvorgänge vorgenommen, die die Aufheizung der Heizspirale 41 auf die gewünschte Temperatur bewirken.Reference is now made to FIGS. 4 and 5. It can be seen here that the inner container 30 is embedded in an insulation 300 and this in turn is enclosed by an outer container 205 which covers the inner container 30 and which has an approximately cuboidal box shape. The heating coil 41, which is inserted into the circular opening 42 of the inner container 30, can also be seen in FIGS. 4 and 5. As can be seen, the conical component 200 accommodates in its interior in the outer area a control unit 202 with a thermostat, which is attached to the disk 203 on the inside thereof. This disk 203 is in turn provided with webs on the circumference and is placed with these webs on the webs 200a and the ring web 200b of the conical component 200 and thus fastened to it. A fastening axis 206 protrudes through a bore in the outer container 205, on which the rotatable axis then turns Control element 204 can be plugged in, by means of which the desired heating temperature can be set by acting on the control unit 202 from the outside of the outer container 205 with the hot water tank installed. The corresponding switching operations are then carried out via a circuit, which is not shown in detail here, which bring about the heating of the heating coil 41 to the desired temperature.

Fig. 6 zeigt noch einmal die Draufsicht auf den Außenbehälter 205 für den erfindungsgemäßen Warmwasserspeicher gemäß den Fig. 4 und 5, wobei dieser Außenbehälter 205 teilweise aufgeschnitten ist, so daß man den Innenbehälter 30 erkennen kann und das kegelförmige Bauelement 200, das in den Trichter 20b des Innenbehälters 30 eingesetzt ist. Man erkennt weiterhin hier die Regelungsbaueinheit 202, die auf das kegelförmige Bauelement 200 aufgesteckte Scheibe 203 und das drehbare Bedienelement 204. Weiterhin erkennt man die aus dem Außenbehälter 205 nach oben hin austretenden Anschlüsse für den Ablaufkanal 28 und den Zulaufkanal 27.Fig. 6 shows again the top view of the outer container 205 for the hot water tank according to the invention according to FIGS. 4 and 5, this outer container 205 being partially cut open so that the inner container 30 can be seen and the conical component 200 which is in the funnel 20b of the inner container 30 is inserted. The control unit 202, the disk 203 attached to the conical component 200 and the rotatable control element 204 can also be seen here. Furthermore, the connections for the outlet channel 28 and the inlet channel 27 emerging from the outer container 205 can be seen.

Das kegelförmige Bauelement 200 ist ja in den Fig. 2 und 3 im Schnitt erkennbar. Zum besseren Verständnis ist in Fig. 7 noch mal eine Ansicht dieses kegelförmigen Bauelements 200 in Richtung dessen Achse betrachtet wiedergegeben. Man erkennt die vier Stege 200a und den Kegelstumpf 200c.The conical component 200 can be seen in section in FIGS. 2 and 3. For a better understanding, a view of this conical component 200 in the direction of its axis is shown in FIG. 7 again. The four webs 200a and the truncated cone 200c can be seen.

In den Fig. 8 und 9 ist die Scheibe 203 noch einmal vergrößert im Detail wiedergegeben. Man erkennt in Fig. 8, daß die Scheibe Durchbrechungen und Bohrungen für Montagezwecke aufweist und man kann aus Fig. 9 erkennen, daß der Rand der Scheibe 203 eine Art Nut 203a hat, die bei aufgesteckter Scheibe 203 den Rand des Ringstegs 200b des kegelförmigen Bauelements 200 aufnimmt.8 and 9, the disk 203 is shown enlarged again in detail. It can be seen in Fig. 8 that the disc has openings and bores for assembly purposes and it can be seen from Fig. 9 that the edge of the disc 203 has a kind of groove 203a which, when the disc 203 is attached, the edge of the ring land 200b of the conical component 200 records.
