Ferner soll unter einer "Stellposition" insbesondere eine Position und/oder eine Schaltstellung, insbesondere eine Öffnungsstellung und/oder eine Verschlussstellung, des Fluidventils verstanden werden. Insbesondere ist eine die Fluidleitung durchströmende Fluidmenge des Fluidstroms und/oder ein die Fluidleitung durchströmendes Fluidvolumen des Fluidstroms in verschiedenen Stellpositionen des Fluidventils unterschiedlich. Vorteilhaft entsprechen zumindest zwei Stellpositionen der zumindest drei Stellpositionen Öffnungsstellungen des Fluidventils, in welchen insbesondere ein Fluidstrom und/oder eine Zufuhr des Fluidstroms zu der Heizeinheit ermöglicht ist. Besonders bevorzugt ist zumindest eines der Fluidventile dazu vorgesehen, in den verschiedenen Stellpositionen, insbesondere Öffnungsstellungen, einen Betrieb an zumindest zwei unterschiedliche Fluidtypen anzupassen. Dabei soll unter einem "Fluidtyp" insbesondere eine Art und/oder eine Zusammensetzung des Fluids, insbesondere des Fluidstroms, verstanden werden. Durch eine entsprechende Ausgestaltung der Heizgerätevorrichtung kann insbesondere eine Flexibilität der Heizgerätevorrichtung verbessert werden. Dabei kann insbesondere ein Heizgerät bereitgestellt werden, welches vorteilhaft, insbesondere ohne ein manuelles Eingreifen durch einen Benutzer, an sich ändernde Bedingungen, wie beispielsweise unterschiedliche Fluidtypen, angepasst werden kann, wodurch insbesondere Kosten minimiert, eine Heizleistungseffizienz optimiert und/oder eine Wartung erleichtert werden kann. Zudem kann vorteilhaft ein Steueralgorithmus und/oder eine Komplexität eines Steuerprogramms vereinfacht werden.In this context, a "heating unit" is to be understood as meaning, in particular, a unit which is provided in particular to, in at least one operating state, at least one mixture, advantageously comprising the fluid flow and / or a fluid of the fluid flow, advantageously comprising a combustion air and a fuel, to burn. A “fluid valve” is also to be understood in particular as a valve, advantageously a flow valve, which is in particular connected to the fluid line and which is provided for shutting off and / or regulating the fluid flow. The fluid valve can be designed as any, in particular electrical, electromagnetic, pneumatic and / or hydraulic fluid valve, such as, for example, as a continuous valve, in particular a proportional valve, control valve and / or servo valve. Furthermore, a “set position” is to be understood in particular as a position and / or a switching position, in particular an open position and / or a closed position, of the fluid valve. In particular, an amount of fluid of the fluid flow flowing through the fluid line and / or a fluid volume of the fluid flow flowing through the fluid line is different in different setting positions of the fluid valve. At least two setting positions of the at least three setting positions advantageously correspond to opening positions of the fluid valve in which, in particular, a fluid flow and / or a supply of the fluid flow to the heating unit is made possible. Particularly preferably, at least one of the fluid valves is provided to adapt operation to at least two different types of fluid in the various setting positions, in particular open positions. A “fluid type” is to be understood as meaning, in particular, a type and / or a composition of the fluid, in particular of the fluid flow. A corresponding configuration of the heater device can in particular improve the flexibility of the heater device. In particular, a heating device can be provided which can advantageously be adapted to changing conditions, such as different fluid types, in particular without manual intervention by a user, thereby minimizing costs, heating power efficiency can be optimized and / or maintenance can be facilitated. In addition, a control algorithm and / or a complexity of a control program can advantageously be simplified.

Die Fluidventile sind fluidtechnisch in Reihe geschalten, damit eine besonders einfache Ansteuerung erreicht werden kann.The fluid valves are connected in series in terms of fluid technology so that particularly simple control can be achieved.

Der Fluidstrom könnte beispielsweise einem Luftstrom, insbesondere einem Verbrennungsluftstrom, entsprechen. Eine vorteilhaft optimierte Heizleistungseffizienz kann jedoch insbesondere dann erreicht werden, wenn der Fluidstrom ein, vorteilhaft gasförmiger, Brennstoffstrom ist.The fluid flow could, for example, correspond to an air flow, in particular a combustion air flow. However, an advantageously optimized heating power efficiency can be achieved in particular when the fluid flow is an advantageously gaseous fuel flow.

Ferner wird vorgeschlagen, dass das erste Fluidventil in einem Nahbereich des zweiten Fluidventils angeordnet ist. Unter einem "Nahbereich" soll insbesondere ein räumlicher Bereich verstanden werden, welcher aus Punkten gebildet ist, die weniger als eine einfache Haupterstreckung, vorzugsweise weniger als eine Hälfte einer Haupterstreckung und besonders bevorzugt weniger als ein Drittel einer Haupterstreckung des ersten Fluidventils und/oder des zweiten Fluidventils von einem Referenzpunkt und/oder einem Referenzbauteil entfernt sind und/oder die jeweils einen Abstand von höchstens 50 cm, vorteilhaft von höchstens 30 cm, vorzugsweise von höchstens 15 cm und besonders bevorzugt von höchstens 5 cm von einem Referenzpunkt und/oder einem Referenzbauteil aufweisen. Unter einer "Haupterstreckung" eines Objekts soll in diesem Zusammenhang insbesondere eine Erstreckung des Objekts in eine Haupterstreckungsrichtung des Objekts verstanden werden. Unter einer "Haupterstreckungsrichtung" eines Objekts soll insbesondere eine Richtung verstanden werden, welche parallel zu einer längsten Kante und/oder Seite eines kleinsten das Objekt gerade noch umschließenden, insbesondere gedachten, Quaders ist. Hierdurch kann insbesondere eine besonders exakte Steuerung erreicht werden.It is also proposed that the first fluid valve is arranged in a close vicinity of the second fluid valve. A "near area" is to be understood in particular as a spatial area which is formed from points that are less than a simple main extension, preferably less than half of a main extension and particularly preferably less than a third of a main extension of the first fluid valve and / or the second Fluid valve are removed from a reference point and / or a reference component and / or each have a distance of at most 50 cm, advantageously of at most 30 cm, preferably of at most 15 cm and particularly preferably of at most 5 cm from a reference point and / or a reference component . A “main extension” of an object is to be understood in this context in particular as an extension of the object in a main extension direction of the object. A "main direction of extent" of an object is to be understood in particular as a direction which is parallel to a longest edge and / or side of a smallest, in particular imaginary, cuboid that just encloses the object. In particular, particularly precise control can be achieved in this way.

In einer Ausgestaltung der Erfindung wird vorgeschlagen, dass die Heizgerätevorrichtung eine Ventilbaugruppe umfasst, welche das erste Fluidventil und das zweite Fluidventil aufweist. Unter einer "Ventilbaugruppe" soll in diesem Zusammenhang insbesondere eine bauliche, insbesondere räumlich begrenzte, Einheit verstanden werden. Vorteilhaft sind das erste Fluidventil und das zweite Fluidventil dabei in einem gemeinsamen Gehäuse angeordnet. Hierdurch kann insbesondere eine besonders kompakte und kosteneffiziente Heizgerätevorrichtung bereitgestellt werden.In one embodiment of the invention, it is proposed that the heater device comprises a valve assembly which has the first fluid valve and the second fluid valve. In this context, a “valve assembly” is to be understood in particular as a structural, in particular spatially limited, unit. The first fluid valve and the second fluid valve are advantageously arranged in a common housing. In this way, a particularly compact and cost-efficient heater device can be provided in particular.

Erfindungsgemäß sind die Fluidventile wesentlich verschieden voneinander ausgebildet. Unter "wesentlich verschiedenen" Objekten sollen dabei insbesondere Objekte verstanden werden, welche sich insbesondere in ihrer Funktionsweise und/oder ihrem Aufbau zumindest teilweise unterscheiden. Hierdurch kann insbesondere eine besonders flexible Heizgerätevorrichtung bereitgestellt werden, welche vorteilhaft an unterschiedliche Bedingungen angepasst werden kann.According to the invention, the fluid valves are designed to be substantially different from one another. "Substantially different" objects are to be understood in particular to mean objects which at least partially differ in particular in their mode of operation and / or their structure. In this way, in particular, a particularly flexible heater device can be provided which can advantageously be adapted to different conditions.

Die Heizgerätevorrichtung könnte beispielsweise zumindest ein als reines Absperrventil ausgebildetes Fluidventil umfassen, welches insbesondere dazu vorgesehen ist, den Fluidstrom zumindest im Wesentlichen komplett zu unterbrechen. Unter einem "reinen Absperrventil" soll in diesem Zusammenhang insbesondere ein Fluidventil mit genau zwei Stellpositionen, insbesondere einer Öffnungsstellung und einer Verschlussstellung, verstanden werden. Vorteilhaft wird jedoch vorgeschlagen, dass zumindest das erste Fluidventil dazu vorgesehen ist, den Fluidstrom, insbesondere in der Verschlussstellung, zumindest im Wesentlichen komplett, insbesondere zumindest im Rahmen fertigungstechnischer Möglichkeiten und/oder im Rahmen, insbesondere für einen ordnungsgemäßen Betrieb, zulässiger Toleranzen komplett, zu unterbrechen. Hierdurch können insbesondere Kosten reduziert und/oder ein Wartungsaufwand und damit insbesondere eine Standzeit und/oder eine Dauerfestigkeit optimiert werden. Zudem kann eine kompakte Ausgestaltung erreicht werden.The heater device could, for example, comprise at least one fluid valve designed as a pure shut-off valve, which is provided in particular to at least substantially completely interrupt the fluid flow. In this context, a “pure shut-off valve” is to be understood as meaning, in particular, a fluid valve with precisely two control positions, in particular an open position and a closed position. Advantageously, however, it is proposed that at least the first fluid valve is provided to completely close the fluid flow, in particular in the closed position, at least essentially completely, in particular at least within the scope of manufacturing possibilities and / or within the framework, in particular for proper operation, of permissible tolerances interrupt. As a result, in particular costs can be reduced and / or maintenance expenditure and thus in particular a service life and / or fatigue strength can be optimized. In addition, a compact design can be achieved.

Erfindungsgemäß wird vorgeschlagen, dass das erste Fluidventil zumindest zu einer Grobregelung des Fluidstroms vorgesehen ist. In diesem Zusammenhang soll unter einer "Grobregelung" insbesondere eine Regelung verstanden werden, wobei eine Regelgröße von einer Sollgröße wesentlich abweichen kann, ein Trend und/oder eine Tendenz der Regelgröße jedoch vorteilhaft entsprechend der Sollgröße verläuft. Darunter, dass eine "Größe wesentlich von einer weiteren Größe abweicht", soll insbesondere verstanden werden, dass ein Wert der Größe um wenigstens 5 %, vorzugsweise um wenigstens 10 % und besonders bevorzugt um wenigstens 20 % von einem Wert der weiteren Größe abweicht. In diesem Fall ist das erste Fluidventil als Drosselventil ausgebildet. Hierdurch kann insbesondere eine einfache und/oder kostengünstige Anpassung des Fluidstroms erreicht werden. Ferner wird vorgeschlagen, dass zumindest das zweite Fluidventil zu einer Feinregelung des Fluidstroms vorgesehen ist. In diesem Zusammenhang soll unter einer "Feinregelung" insbesondere eine zumindest im Wesentlichen exakte, insbesondere eine zumindest im Rahmen fertigungstechnischer Möglichkeiten und/oder im Rahmen, insbesondere für einen ordnungsgemäßen Betrieb, zulässiger Toleranzen exakte, Regelung verstanden werden, wobei die Regelgröße insbesondere zumindest im Wesentlichen der Sollgröße entspricht. In diesem Fall ist das zweite Fluidventil als Regelventil ausgebildet. Hierdurch kann insbesondere ein zu einer Verbrennung benötigter, Fluidstrom vorteilhaft exakt eingestellt werden.According to the invention it is proposed that the first fluid valve is provided at least for a coarse regulation of the fluid flow. In this context, “coarse control” is to be understood as meaning, in particular, a control system in which a controlled variable can differ significantly from a setpoint, but a trend and / or a tendency of the controlled variable advantageously runs according to the setpoint. The fact that a "size differs significantly from a further size" is to be understood in particular as meaning that a value of the size deviates by at least 5%, preferably by at least 10% and particularly preferably by at least 20% from a value of the further size. In this case, the first fluid valve is designed as a throttle valve. In this way, a simple and / or inexpensive adaptation of the fluid flow can be achieved in particular. It is further proposed that at least the second fluid valve is provided for fine control of the fluid flow. In this context, under a "fine control" in particular an at least essentially exact, in particular at least within the scope of manufacturing possibilities and / or within the scope, in particular for proper operation, of permissible tolerances exact, control, wherein the controlled variable in particular corresponds at least substantially to the target variable. In this case, the second fluid valve is designed as a control valve. In this way, in particular, a fluid flow required for combustion can advantageously be set exactly.

Insbesondere, jedoch nicht ausschließlich, im Fall, dass das erste Fluidventil zumindest zu einer Grobregelung des Fluidstroms und das zweite Fluidventil zu einer Feinregelung des Fluidstroms vorgesehen ist, ist das erste Fluidventil in Strömungsrichtung, insbesondere des Fluidstroms, gesehen vorteilhaft vor dem zweiten Fluidventil angeordnet. Hierdurch können insbesondere nicht-lineare Effekte, insbesondere bei einem nahezu vollständig geschlossenen Fluidventil, insbesondere zweiten Fluidventil, verhindert werden, wodurch insbesondere eine besonders vorteilhafte Einstellung und/oder Regelung des Fluidstroms erreicht werden kann.In particular, but not exclusively, in the event that the first fluid valve is provided at least for coarse control of the fluid flow and the second fluid valve for fine control of the fluid flow, the first fluid valve is advantageously arranged upstream of the second fluid valve when viewed in the direction of flow, in particular of the fluid flow. In this way, in particular, non-linear effects, in particular in the case of an almost completely closed fluid valve, in particular a second fluid valve, can be prevented, whereby in particular a particularly advantageous setting and / or regulation of the fluid flow can be achieved.

Die Fluidventile sind als Automatikventile ausgebildet. Unter einem "Automatikventil" soll dabei insbesondere ein, insbesondere von einem Handventil und/oder, insbesondere von einem Benutzer und/oder Bediener, manuell verstellbaren Fluidventil, verschieden ausgebildetes, insbesondere elektrisch, elektromagnetisch, pneumatisch und/oder hydraulisch ansteuerbares, Fluidventil verstanden werden. Hierdurch kann insbesondere eine besonders einfache Ansteuerung erreicht werden. Zudem kann eine Einsatzvielfalt erhöht und/oder ein vorteilhaft autonom arbeitendes Heizgerät bereitgestellt werden, wodurch insbesondere eine Wartung vereinfacht werden kann.The fluid valves are designed as automatic valves. An "automatic valve" is to be understood in particular as a fluid valve, in particular a manual valve and / or, in particular by a user and / or operator, manually adjustable fluid valve, differently designed, in particular electrically, electromagnetically, pneumatically and / or hydraulically controllable fluid valve. In particular, this enables particularly simple control to be achieved. In addition, a variety of uses can be increased and / or an advantageously autonomously operating heater can be provided, which in particular can simplify maintenance.

Zudem geht die Erfindung aus von einem Verfahren mit einer Heizgerätevorrichtung nach Anspruch 1, insbesondere einer Öl- und/oder Gasbrennervorrichtung, welche zumindest ein erstes Fluidventil aufweist, welches dazu vorgesehen ist, zumindest einen, vorteilhaft genau einen, Fluidstrom, vorteilhaft einen gasförmigen Fluidstrom, zumindest im Wesentlichen komplett zu unterbrechen, wobei ein Betrieb zumindest teilweise mittels des ersten Fluidventils an zumindest zwei unterschiedliche Fluidtypen angepasst wird.In addition, the invention is based on a method with a heating device device according to claim 1, in particular an oil and / or gas burner device, which has at least one first fluid valve which is provided for at least one, advantageously exactly one, fluid flow, advantageously a gaseous fluid flow, to interrupt at least substantially completely, wherein an operation is at least partially adapted to at least two different fluid types by means of the first fluid valve.

Erfindungsgemäß weist die Heizgerätevorrichtung ferner ein zweites Fluidventil auf, welches dazu vorgesehen ist, gemeinsam mit dem ersten Fluidventil den Fluidstrom zu variieren. Hierdurch kann insbesondere eine Flexibilität erhöht, Kosten reduziert und/oder ein Wartungsaufwand und damit insbesondere eine Standzeit und/oder eine Dauerfestigkeit optimiert werden.According to the invention, the heater device furthermore has a second fluid valve which is provided to vary the fluid flow together with the first fluid valve. In this way, in particular, flexibility can be increased, costs reduced and / or maintenance expenditure and thus in particular a service life and / or fatigue strength optimized.

Dabei ist an der Einlassöffnung 24 und der Auslassöffnung 26 jeweils ein Gewindeflansch angeordnet, welche zu einem Anschluss einer nicht dargestellten Fluidzuleitung und/oder einer nicht dargestellten Fluidableitung vorgesehen sind. Die Fluidableitung ist im vorliegenden Fall dazu vorgesehen, den Fluidstrom einer Heizeinheit (nicht dargestellt) zuzuführen.The heater device comprises a valve assembly 14. The valve assembly 14 is designed as a structural unit. The valve assembly 14 is designed as a compact unit. In the present case, the valve assembly 14 is designed as a gas combination regulator. The valve assembly 14 comprises a housing 20. The housing 20 is designed as a flow housing. In addition, the housing 20 is formed in one piece in the present case. Alternatively, it is conceivable to design a housing in several parts. The housing 20 has an inlet opening 24 and an outlet opening 26. The inlet opening 24 is provided for introducing a fluid flow, in the present case in particular a gaseous flow. The fluid stream is a fuel stream. Alternatively, however, it is also conceivable that a fluid flow corresponds to a combustion air flow, a mixed flow, in particular of a combustion air and a fuel, and / or a liquid fuel. The outlet opening 26 is provided for discharging the fluid flow. In this case, a threaded flange is arranged on the inlet opening 24 and the outlet opening 26, which are provided for a connection of a fluid feed line (not shown) and / or a fluid discharge line (not shown). The fluid discharge is provided in the present case to feed the fluid flow to a heating unit (not shown).

Die Ventilbaugruppe 14 und/oder das Gehäuse 20 definieren ferner eine Fluidleitung 22. Die Fluidleitung 22 verbindet die Einlassöffnung 24 mit der Auslassöffnung 26. Die Fluidleitung 22 ist dazu vorgesehen, den Fluidstrom zumindest teilweise zu führen.The valve assembly 14 and / or the housing 20 further define a fluid line 22. The fluid line 22 connects the inlet opening 24 with the outlet opening 26. The fluid line 22 is provided to at least partially guide the fluid flow.

Darüber hinaus weist die Ventilbaugruppe 14 zumindest zwei Fluidventile 10, 12 auf. Im vorliegenden Fall umfasst die Ventilbaugruppe 14 genau zwei Fluidventile 10, 12. Die Fluidventile 10, 12 stehen mit der Fluidleitung 22 in Verbindung. Die Fluidventile 10, 12 sind unabhängig voneinander ansteuerbar. Die Fluidventile 10, 12 sind dabei fluidtechnisch in Reihe geschalten. Ein erstes Fluidventil 10 ist in Strömungsrichtung 16 des Fluidstroms gesehen vor einem zweiten Fluidventil 12 angeordnet.In addition, the valve assembly 14 has at least two fluid valves 10, 12.

Das erste Fluidventil 10 ist als Brennstoffventil ausgebildet. Das erste Fluidventil 10 ist als Automatikventil ausgebildet. Darüber hinaus ist das erste Fluidventil 10 als Drosselventil ausgebildet. Im vorliegenden Fall ist das erste Fluidventil 10 als Magnetventil und/oder Solenoidventil ausgebildet. Das erste Fluidventil 10 ist dabei elektrisch ansteuerbar. Das erste Fluidventil 10 ist somit von einem Handventil und/oder einem manuell verstellbaren Ventil verschieden. Alternativ ist denkbar, ein erstes Fluidventil als Hydraulikventil und/oder als Pneumatikventil auszubilden. Zudem ist denkbar, ein erstes Fluidventil als kontinuierlich einstellbares Absperrventil auszubilden.The first fluid valve 10 is designed as a fuel valve. The first fluid valve 10 is designed as an automatic valve. In addition, the first fluid valve 10 is designed as a throttle valve. In the present case, the first fluid valve 10 is designed as a solenoid valve and / or solenoid valve. The first fluid valve 10 can be controlled electrically. The first fluid valve 10 is thus different from a manual valve and / or a manually adjustable valve. Alternatively, it is conceivable to use a first fluid valve as Train hydraulic valve and / or as a pneumatic valve. It is also conceivable to design a first fluid valve as a continuously adjustable shut-off valve.

Das erste Fluidventil 10 weist eine erste Aktoreinheit 28 auf. Die erste Aktoreinheit 28 ist im vorliegenden Fall als elektromagnetische Aktoreinheit ausgebildet. Die erste Aktoreinheit 28 umfasst eine erste Spule 30. Die erste Spule 30 ist mechanisch in ihrer Position fixiert. Ferner umfasst die erste Aktoreinheit 28 einen ersten Kern 32. Der erste Kern 32 besteht im vorliegenden Fall aus einem ferromagnetischen Material, wie beispielsweise Eisen und/oder Stahl. Alternativ ist jedoch auch denkbar, dass ein erster Kern aus einem beliebigen anderen Material besteht. Der erste Kern 32 ist innerhalb der ersten Spule 30 gelagert. Der erste Kern 32 ist linear beweglich gelagert. Darüber hinaus umfasst das erste Fluidventil 10 ein erstes Drosselelement 34. Das erste Drosselelement 34 ist mit dem ersten Kern 32 verbunden. Im vorliegenden Fall ist das erste Drosselelement 34 mittelbar, insbesondere mittels eines ersten Ventilstößels 36 des ersten Fluidventils 10, mit dem ersten Kern 32 verbunden. Alternativ ist jedoch auch denkbar, ein erstes Drosselelement unmittelbar mit einem ersten Kern zu verbinden und/oder ein erstes Drosselelement und einen ersten Kern einstückig auszubilden. Das erste Drosselelement 34 ist zumindest im Wesentlichen tellerförmig ausgebildet. Zusätzlich kann das erste Drosselelement 34 ein, insbesondere in Umfangrichtung umlaufendes, insbesondere elastisches, Dichtelement umfassen.The first fluid valve 10 has a first actuator unit 28. In the present case, the first actuator unit 28 is designed as an electromagnetic actuator unit. The first actuator unit 28 comprises a first coil 30. The first coil 30 is mechanically fixed in its position. Furthermore, the first actuator unit 28 comprises a first core 32. In the present case, the first core 32 consists of a ferromagnetic material such as iron and / or steel. Alternatively, however, it is also conceivable that a first core consists of any other material. The first core 32 is stored within the first coil 30. The first core 32 is mounted so as to be linearly movable. In addition, the first fluid valve 10 comprises a first throttle element 34. The first throttle element 34 is connected to the first core 32. In the present case, the first throttle element 34 is indirectly connected to the first core 32, in particular by means of a first valve tappet 36 of the first fluid valve 10. Alternatively, however, it is also conceivable to connect a first throttle element directly to a first core and / or to form a first throttle element and a first core in one piece. The first throttle element 34 is at least substantially plate-shaped. In addition, the first throttle element 34 can comprise a sealing element, in particular an elastic, in particular circumferential in the circumferential direction.

Des Weiteren umfasst die erste Aktoreinheit 28 ein erstes elastisches Element 38. Das erste elastische Element 38 ist als Rückstellelement ausgebildet. Das erste elastische Element 38 kann dabei als beliebiges elastisches Element ausgebildet sein, wie beispielsweise als Polymerelement, als Elastomerelement, als Silikonelement und/oder vorzugsweise als Federelement. Im vorliegenden Fall ist das erste elastische Element 38 als Druckfeder ausgebildet. Das erste elastische Element 38 weist eine Wirkverbindung mit dem ersten Kern 32 und/oder dem ersten Drosselelement 34 auf. Das erste elastische Element 38 ist auf einer dem ersten Drosselelement 34 abgewandten Seite des ersten Kerns 32 angeordnet. Das erste elastische Element 38 ist zwischen dem ersten Kern 32 und einer Innenwand des Gehäuses 20 angeordnet. Im vorliegenden Fall ist das erste elastische Element 38 dazu vorgesehen, das erste Drosselelement 34 in zumindest einem Betriebszustand, im vorliegenden Fall insbesondere einem unbestromten Zustand der ersten Aktoreinheit 28, in eine von dem ersten elastischen Element 38 abgewandte Richtung und insbesondere in Richtung eines ersten Ventilsitzes 40 der ersten Fluideinheit 10 zu drücken. Darüber hinaus wirkt im vorliegenden Fall eine Gewichtskraft des ersten Kerns 32 in Richtung des Ventilsitzes 40, wodurch insbesondere ein sicheres Verschließen der Fluidleitung 22 erreicht werden kann.Furthermore, the first actuator unit 28 comprises a first elastic element 38. The first elastic element 38 is designed as a restoring element. The first elastic element 38 can be designed as any elastic element, such as a polymer element, an elastomer element, a silicone element and / or preferably a spring element. In the present case, the first elastic element 38 is designed as a compression spring. The first elastic element 38 has an operative connection with the first core 32 and / or the first throttle element 34. The first elastic element 38 is arranged on a side of the first core 32 facing away from the first throttle element 34. The first elastic element 38 is arranged between the first core 32 and an inner wall of the housing 20. In the present case, the first elastic element 38 is provided to convert the first throttle element 34 in at least one operating state, in the present case in particular a de-energized state of the first actuator unit 28, into one of the first elastic To push element 38 facing away from the direction and in particular in the direction of a first valve seat 40 of the first fluid unit 10. In addition, in the present case, a weight of the first core 32 acts in the direction of the valve seat 40, whereby, in particular, a secure closure of the fluid line 22 can be achieved.

Im vorliegenden Fall ist durch eine Ansteuerung der ersten Aktoreinheit 28, insbesondere einer Beaufschlagung der ersten Spule 30 mit einem Strom, der erste Kern 32 linear gegen eine Federkraft des ersten elastischen Elements 38 bewegbar. Durch die lineare Bewegung des ersten Kerns 32 gegen die Federkraft des ersten elastischen Elements 38 erfolgt ein Abheben des ersten Drosselelements 34 von dem ersten Ventilsitz 40 (vgl. auch Figuren 2 und 3).In the present case, by activating the first actuator unit 28, in particular by applying a current to the first coil 30, the first core 32 can be moved linearly against a spring force of the first elastic element 38. The linear movement of the first core 32 counter to the spring force of the first elastic element 38 causes the first throttle element 34 to lift off the first valve seat 40 (see also FIG Figures 2 and 3 ).

Das zweite Fluidventil 12 ist in einem Nahbereich des ersten Fluidventils 10 angeordnet. Ein minimaler Abstand zwischen dem zweiten Fluidventil 12 und dem ersten Fluidventil 10 beträgt dabei höchstens 10 cm. Das zweite Fluidventil 12 ist als Brennstoffventil ausgebildet.

Das zweite Fluidventil 12 ist wesentlich verschieden von dem ersten Fluidventil 10 ausgebildet. Im vorliegenden Fall ist das zweite Fluidventil 12 als Magnetventil und/oder Solenoidventil ausgebildet. Das zweite Fluidventil 12 ist elektrisch ansteuerbar. Das zweite Fluidventil 12 ist somit von einem Handventil und/oder einem manuell verstellbaren Ventil verschieden. Alternativ ist denkbar, ein zweites Fluidventil als Hydraulikventil und/oder Pneumatikventil auszubilden. Zudem ist denkbar, dass ein, insbesondere als Regelventil ausgebildetes, zweites Fluidventil in Strömungsrichtung eines Fluidstroms gesehen vor einem ersten Fluidventil angeordnet ist.The second fluid valve 12 is arranged in the vicinity of the first fluid valve 10. A minimum distance between the second fluid valve 12 and the first fluid valve 10 is at most 10 cm. The second fluid valve 12 is designed as a fuel valve. The second fluid valve 12 is designed as an automatic valve. In addition, the second fluid valve 12 is designed as a control valve. The second fluid valve 12 is designed to be substantially different from the first fluid valve 10. In the present case, the second fluid valve 12 is designed as a solenoid valve and / or solenoid valve. The second fluid valve 12 can be controlled electrically. The second fluid valve 12 is thus different from a manual valve and / or a manually adjustable valve. Alternatively, it is conceivable to design a second fluid valve as a hydraulic valve and / or pneumatic valve. In addition, it is conceivable that a second fluid valve, in particular designed as a control valve, is arranged upstream of a first fluid valve, seen in the direction of flow of a fluid flow.

Das zweite Fluidventil 12 umfasst eine zweite Aktoreinheit 42. Die zweite Aktoreinheit 42 ist im vorliegenden Fall als Tauchspulenaktoreinheit ausgebildet. Alternativ ist jedoch auch denkbar, eine zweite Aktoreinheit als beliebige andere Aktoreinheit auszubilden. Die zweite Aktoreinheit 42 umfasst eine zweite Spule 44, welche auf einen Spulenträger 46 gewickelt ist. Die zweite Spule 44 und der Spulenträger 46 sind dabei beweglich, insbesondere linear beweglich, gelagert. Ferner umfasst die zweite Aktoreinheit 42 einen zweiten Kern 48. Der zweite Kern 48 besteht im vorliegenden Fall aus einem dauermagnetischen Material. Der zweite Kern 48 ist mechanisch in seiner Position fixiert ist. Die zweite Spule 44 und der Spulenträger 46 sind relativ zu dem zweiten Kern 48 beweglich.The second fluid valve 12 comprises a second actuator unit 42. The second actuator unit 42 is designed as a plunger coil actuator unit in the present case. Alternatively, however, it is also conceivable to design a second actuator unit as any other actuator unit. The second actuator unit 42 comprises a second coil 44 which is wound on a coil carrier 46. The second coil 44 and the coil carrier 46 are movably mounted, in particular movably linearly. Furthermore, the second actuator unit 42 comprises a second core 48. In the present case, the second core 48 consists of a permanently magnetic material. The second core 48 is mechanically fixed in position. The second coil 44 and the coil carrier 46 are movable relative to the second core 48.

Darüber hinaus umfasst das zweite Fluidventil 12 ein zweites Drosselelement 50. Das zweite Drosselelement weist eine Wirkverbindung mit der zweiten Spule 44 und/oder dem Spulenträger 46 auf. Das zweite Drosselelement 50 ist zumindest im Wesentlichen tellerförmig ausgebildet. Das zweite Drosselelement 50 weist ein, insbesondere in Umfangrichtung umlaufendes, insbesondere elastisches, Dichtelement auf. Zudem umfasst das zweite Fluidventil 12 einen zweiten Ventilstößel 52. Der zweite Ventilstößel 52 verbindet das zweite Drosselelement 50 mit der zweiten Spule 44 und/oder dem Spulenträger 46. Im vorliegenden Fall ist der zweite Ventilstößel 52 und das zweite Drosselelement 50 einstückig ausgebildet. Alternativ ist jedoch auch denkbar, einen zweiten Ventilstößel und ein zweites Drosselelement mehrteilig auszubilden. Der zweite Ventilstößel 52 ist dazu vorgesehen, eine Bewegung der zweiten Spule 44 und/oder des Spulenträgers 46 auf das zweite Drosselelement 50 zu übertragen.In addition, the second fluid valve 12 comprises a second throttle element 50. The second throttle element has an operative connection with the second coil 44 and / or the coil carrier 46. The second throttle element 50 is at least substantially plate-shaped. The second throttle element 50 has a sealing element, in particular an elastic, circumferential in particular in the circumferential direction. In addition, the second fluid valve 12 includes a second valve tappet 52. The second valve tappet 52 connects the second throttle element 50 to the second coil 44 and / or the coil carrier 46. In the present case, the second valve tappet 52 and the second throttle element 50 are integrally formed. Alternatively, however, it is also conceivable to design a second valve tappet and a second throttle element in multiple parts. The second valve tappet 52 is provided to transmit a movement of the second coil 44 and / or of the coil carrier 46 to the second throttle element 50.

Darüber hinaus weist das zweite Fluidventil 12 eine Ventilkammer 54 auf. Die Ventilkammer 54 ist dabei einstückig mit der Fluidleitung 22 ausgebildet. Die Ventilkammer 54 ist an einer zu der zweiten Spule 44, dem Spulenträger 46 und/oder dem zweiten Kern 48 zugewandten Seite durch eine Membran 56 abgeschlossen. Die Membran 56 ist flexibel ausgebildet. Die Membran 56 ist mit einem äußeren Umfang an dem Gehäuse 20 befestigt. Die Membran 56 ist mit einem inneren Umfang an dem zweiten Ventilstößel 52 befestigt. Bewegungen des zweiten Ventilstößels 52 führen zu einer entsprechenden Auslenkung der Membran 56, wodurch die Ventilkammer 54 auch bei Bewegungen des zweiten Ventilstößels 52 zuverlässig in Richtung der zweiten Spule 44, des Spulenträgers 46 und/oder des zweiten Kerns 48 abgeschlossen ist. Zudem ist eine der zweiten Spule 44, dem Spulenträger 46 und/oder dem zweiten Kern 48 zugewandte Oberfläche der Membran 56 mit einem Referenzdruck, beispielsweise einem Umgebungsluftdruck, beaufschlagt.In addition, the second fluid valve 12 has a valve chamber 54. The valve chamber 54 is formed in one piece with the fluid line 22. The valve chamber 54 is closed on a side facing the second coil 44, the coil carrier 46 and / or the second core 48 by a membrane 56. The membrane 56 is flexible. The membrane 56 is attached to the housing 20 with an outer circumference. The diaphragm 56 is fastened to the second valve tappet 52 with an inner circumference. Movements of the second valve tappet 52 lead to a corresponding deflection of the diaphragm 56, whereby the valve chamber 54 is reliably closed even when the second valve tappet 52 moves in the direction of the second coil 44, the coil carrier 46 and / or the second core 48. In addition, a surface of the membrane 56 facing the second coil 44, the coil carrier 46 and / or the second core 48 is acted upon by a reference pressure, for example an ambient air pressure.

Des Weiteren umfasst das zweite Fluidventil 12 ein zweites elastisches Element 58. Das zweite elastische Element 58 ist als Rückstellelement ausgebildet. Das zweite elastische Element 58 kann dabei als beliebiges elastisches Element ausgebildet sein, wie beispielsweise als Polymerelement, als Elastomerelement, als Silikonelement und/oder vorzugsweise als Federelement. Im vorliegenden Fall ist das zweite elastische Element 58 als Druckfeder ausgebildet. Das zweite elastische Element 58 weist eine Wirkverbindung mit dem zweiten Drosselelement 50 auf. Im vorliegenden Fall kontaktiert das zweite elastische Element 58 das zweite Drosselelement 50 unmittelbar. Das zweite elastische Element 58 ist zwischen dem zweiten Drosselelement 50 und einer, insbesondere der Innenwand gegenüberliegenden, weiteren Innenwand des Gehäuses 20 angeordnet. Im vorliegenden Fall ist das zweite elastische Element 58 dazu vorgesehen, das zweite Drosselelement 50 in zumindest einem Betriebszustand in eine von dem zweiten elastischen Element 58 abgewandte Richtung und insbesondere in Richtung eines zweiten Ventilsitzes 60 der zweiten Fluideinheit 12 zu bewegen. Darüber hinaus wirkt im vorliegenden Fall eine Gewichtskraft des zweiten Drosselelements 50 und des zweiten Ventilstößels 52 in Richtung des zweiten elastischen Elements 58, wodurch insbesondere ein exaktere Regelung des Fluidstroms erreicht werden kann.Furthermore, the second fluid valve 12 comprises a second elastic element 58. The second elastic element 58 is designed as a restoring element. The second elastic element 58 can be designed as any elastic element, such as a polymer element, an elastomer element, a silicone element and / or preferably a spring element. In the present case, the second elastic element 58 is designed as a compression spring. The second elastic element 58 has an operative connection with the second throttle element 50. In the present case, the second elastic element 58 makes direct contact with the second throttle element 50. The second elastic element 58 is arranged between the second throttle element 50 and a further inner wall of the housing 20, in particular opposite the inner wall. In the present case, the second elastic element 58 is provided to move the second throttle element 50 in at least one operating state in a direction facing away from the second elastic element 58 and in particular in the direction of a second valve seat 60 of the second fluid unit 12. Furthermore, in the present case, a weight of the second throttle element 50 and the second valve tappet 52 acts in the direction of the second elastic element 58, whereby in particular a more precise regulation of the fluid flow can be achieved.

Im vorliegenden Fall wirkt bei einer Ansteuerung der zweiten Aktoreinheit 42, insbesondere einer Beaufschlagung der zweiten Spule 44 mit einem Strom, auf die zweite Spule 44 und somit auf den Spulenträger 46 eine Lorentzkraft, die den Spulenträger 46 entlang des zweiten Kerns 48 verlagert, insbesondere mittels einer linearen Bewegung. Die Kraft ist dabei proportional zu einer Stromstärke. Eine Richtung des Kraftvektors ist insbesondere von einer Stromrichtung bestimmt. Die Bewegung des Spulenträgers 46 wird über den zweiten Ventilstößel 52 auf das zweite Drosselelement 50 übertragen. Bei einem Öffnen des zweiten Fluidventils 12 wird das zweite Drosselelement 50 somit entgegen der Federkraft des zweiten elastischen Elements 58 von dem zweiten Ventilsitz 60 wegbewegt.In the present case, when the second actuator unit 42 is activated, in particular when a current is applied to the second coil 44, a Lorentz force acts on the second coil 44 and thus on the coil carrier 46, which displaces the coil carrier 46 along the second core 48, in particular by means of a linear movement. The force is proportional to a current strength. A direction of the force vector is determined in particular by a current direction. The movement of the coil carrier 46 is transmitted to the second throttle element 50 via the second valve tappet 52. When the second fluid valve 12 is opened, the second throttle element 50 is thus moved away from the second valve seat 60 counter to the spring force of the second elastic element 58.

Darüber hinaus umfasst die Heizgerätevorrichtung eine Steuereinheit (nicht dargestellt). Die Steuereinheit ist dazu vorgesehen, Ansteuersignale zur Ansteuerung der Fluidventile 10, 12 bereitzustellen. Die Steuereinheit ist dazu vorgesehen, die Fluidventile 10, 12 mittels eines beliebigen Ansteuersignals anzusteuern, wie beispielsweise mittels eines elektrischen Signals, insbesondere einem Strom und/oder einer Spannung und vorteilhaft einem PWM-Signal.In addition, the heater device comprises a control unit (not shown). The control unit is provided to provide control signals for controlling the fluid valves 10, 12. The control unit is provided to control the fluid valves 10, 12 by means of any control signal, such as for example by means of an electrical signal, in particular a current and / or a voltage and advantageously a PWM signal.

Im vorliegenden Fall sind die Fluidventile 10, 12 dazu vorgesehen, den Fluidstrom gemeinsam zu variieren. Dabei weisen die Fluidventile 10, 12 jeweils zumindest drei Stellpositionen auf. Im vorliegenden Fall weist das erste Fluidventil 10, welches insbesondere als Drosselventil ausgebildet ist, genau drei Stellpositionen auf (vgl. insbesondere Figuren 1 bis 3). Eine erste Stellposition des ersten Fluidventils 10 entspricht dabei einer Verschlussstellung, während die zwei weiteren Stellpositionen des ersten Fluidventils 10 Öffnungsstellungen entsprechen (vgl. Figuren 1 bis 3). Die unterschiedlichen Öffnungsstellen sind dabei mittels einer unterschiedlichen Ansteuerung der ersten Aktoreinheit 28, insbesondere mittels einer Beaufschlagung der ersten Spule 30 mit unterschiedlichen Stromstärken, erreichbar, wodurch sich insbesondere unterschiedliche Gleichgewichtszustände zwischen einer magnetischen Kraft des ersten Kerns 32 und der Federkraft des ersten elastischen Elements 38 ergeben. Das erste Fluidventil 10 ist dabei zu einer Grobregelung des Fluidstroms vorgesehen. Zudem ist das erste Fluidventil 10 dazu vorgesehen, in zumindest einem Betriebszustand den Fluidstrom zumindest im Wesentlichen komplett zu unterbrechen (vgl. insbesondere Figur 1). Das erste Drosselelement 34 dient dabei als Absperrelement. Alternativ ist jedoch auch denkbar, zumindest ein, insbesondere zusätzliches, als reines Absperrventil ausgebildetes, Fluidventil vorzusehen, welches insbesondere dazu vorgesehen sein kann, in zumindest einem Betriebszustand einen Fluidstrom zumindest im Wesentlichen komplett zu unterbrechen. Zudem ist denkbar, ein erstes Fluidventil als Regelventil auszubilden und insbesondere zumindest im Wesentlichen gleichförmig mit dem zweiten Fluidventil zu regeln.In the present case, the fluid valves 10, 12 are provided to vary the fluid flow together. The fluid valves 10, 12 each have at least three setting positions. In the present case, the first fluid valve 10, which is designed in particular as a throttle valve, has exactly three setting positions (cf. in particular Figures 1 to 3 ). A first set position of the first fluid valve 10 corresponds to a closed position, while the two further set positions of the first fluid valve 10 correspond to open positions (cf. Figures 1 to 3 ). The different Opening points can be reached by means of a different control of the first actuator unit 28, in particular by applying different currents to the first coil 30, which in particular results in different states of equilibrium between a magnetic force of the first core 32 and the spring force of the first elastic element 38. The first fluid valve 10 is provided for coarse regulation of the fluid flow. In addition, the first fluid valve 10 is provided to at least substantially completely interrupt the fluid flow in at least one operating state (cf. in particular Figure 1 ). The first throttle element 34 serves as a shut-off element. Alternatively, however, it is also conceivable to provide at least one, in particular additional, fluid valve designed as a pure shut-off valve, which can be provided in particular to at least substantially completely interrupt a fluid flow in at least one operating state. In addition, it is conceivable to design a first fluid valve as a control valve and, in particular, to control it at least substantially uniformly with the second fluid valve.

Das zweite Fluidventil 12, welches insbesondere als Regelventil ausgebildet ist, weist mehr als drei Stellpositionen auf, im vorliegenden Fall insbesondere eine beliebige Anzahl an Stellpositionen. Das zweite Fluidventil 12 ist dabei zu einer Feinregelung des Fluidstroms vorgesehen. Ferner weist das zweite Fluidventil 12 im vorliegenden Fall in einem fast geschlossenen Zustand einen nicht-linearen Regelbereich auf, sodass insbesondere im fast geschlossenen Zustand eine nicht-lineare Änderung der Stellpositionen des zweiten Fluidventils auftritt, wodurch insbesondere eine exakte Regelung des Fluidstroms, insbesondere bei einer geringen Fluidmenge, erschwert ist.The second fluid valve 12, which is designed in particular as a control valve, has more than three control positions, in the present case in particular any number of control positions. The second fluid valve 12 is provided for fine control of the fluid flow. Furthermore, in the present case, the second fluid valve 12 has a non-linear control range in an almost closed state, so that a non-linear change in the actuating positions of the second fluid valve occurs, in particular in the almost closed state, whereby in particular an exact control of the fluid flow, in particular during a small amount of fluid, is difficult.

Das erste Fluidventil 10 ist dazu vorgesehen, einen, insbesondere zusätzlichen, Druckabfall in den Fluidstrom einzubringen, insbesondere mittels der unterschiedlichen Stellpositionen des ersten Fluidventils 10. Durch diesen zusätzlichen Druckabfall wird erreicht, dass das zweite Fluidventil 12, insbesondere bei einer Regelung der gleichen Fluidmenge, weiter geöffnet werden kann und somit in einem von dem nicht-linearen Regelbereich verschiedenen, insbesondere linearen, Regelbereich betrieben werden kann. Zudem kann eine höhere Auflösung des zweiten Fluidventils 12 erreicht werden. Somit kann vorteilhaft eine Kontrollierbarkeit und/oder eine Regelung des Fluidstroms, insbesondere auch bei geringen Fluidmengen, verbessert werden.The first fluid valve 10 is provided to introduce an, in particular additional, pressure drop into the fluid flow, in particular by means of the different setting positions of the first fluid valve 10. This additional pressure drop ensures that the second fluid valve 12, in particular when regulating the same amount of fluid, can be opened further and can thus be operated in a different, in particular linear, control range from the non-linear control range. In addition, a higher resolution of the second fluid valve 12 can be achieved. Thus, controllability and / or regulation of the fluid flow can advantageously be improved, in particular even with small amounts of fluid.

Darüber hinaus ist das erste Fluidventil 10 im vorliegenden Fall dazu vorgesehen, in den verschiedenen Stellpositionen, insbesondere Öffnungsstellungen, einen Betrieb an zumindest zwei unterschiedliche Fluidtypen, im vorliegenden Fall insbesondere Brennstofftypen, anzupassen, insbesondere automatisch und insbesondere ohne manuelles Eingreifen durch einen Benutzer. Ein Brennstofftyp kann dabei einer Gasfamilie, wie beispielsweise einer zweiten Gasfamilie, insbesondere Erdgas, und/oder einer dritten Gasfamilie, insbesondere Flüssiggas, entsprechen. Alternativ oder zusätzlich kann der Brennstofftyp insbesondere auch Brennstoffen derselben Gasfamilie und/oder Brennstoffen innerhalb einer Gasfamilie, wie beispielsweise Brennstoffen unterschiedlicher Herkunft und/oder unterschiedlicher Chargen, entsprechen, welche sich insbesondere zumindest teilweise in einer Zusammensetzung unterscheiden können. Im vorliegenden Fall entspricht das erste Fluidventil 10 somit einem Fluidtyp-Umschalter, im vorliegenden Fall insbesondere einem Gasarten-Umschalter, zur Anpassung des Betriebs an Erd- und/oder Flüssiggas. Erfindungsgemäß weist das erste Fluidventil zwischen drei und zwanzig Stellpositionen auf,
und ist insbesondere zu einer Vorreglung eines Fluidstroms vorgesehen. In diesem Fall kann ein Ansteuersignal des ersten Fluidventils analog zu einem Ansteuersignal eines zweiten Fluidventils kontinuierlich an einen geforderten Fluidstrom angepasst werden.
In addition, the first fluid valve 10 is provided in the present case to adapt operation to at least two different fluid types, in the present case in particular fuel types, in the various setting positions, in particular open positions, in particular automatically and in particular without manual intervention by a user. A fuel type can correspond to a gas family, such as a second gas family, in particular natural gas, and / or a third gas family, in particular liquid gas. Alternatively or additionally, the fuel type can in particular also correspond to fuels of the same gas family and / or fuels within a gas family, such as fuels of different origins and / or different batches, which in particular can differ at least partially in terms of composition. In the present case, the first fluid valve 10 thus corresponds to a fluid type switch, in the present case in particular a gas type switch, for adapting the operation to natural gas and / or liquid gas. According to the invention, the first fluid valve has between three and twenty setting positions,
and is provided in particular for a pre-regulation of a fluid flow. In this case, a control signal of the first fluid valve can be continuously adapted to a required fluid flow analogously to a control signal of a second fluid valve.
