Unter "einstückig" soll insbesondere zumindest stoffschlüssig verbunden, wie beispielsweise durch einen Schweißprozess und/oder Klebeprozess usw., und besonders vorteilhaft angeformt verstanden werden, wie durch die Herstellung aus einem Guss und/oder durch die Herstellung in einem Ein- oder Mehrkomponentenspritzverfahren. Durch ein Verschwenken und/oder ein Verformen und/oder vorzugsweise ein Verfahren des zumindest einen Drosselelements relativ zu dem zumindest einen Ventilsitz ist zumindest ein Spalt zwischen dem zumindest einen Drosselelement und dem zumindest einen Ventilsitz vergrößerbar und/oder verkleinerbar und/oder zumindest im Wesentlichen vollständig verschließbar. Unter einem "Federelement" soll insbesondere ein Element verstanden werden, das zumindest eine Erstreckung aufweist, die in einem normalen Betriebszustand um zumindest 10 %, insbesondere um wenigstens 20 %, vorzugsweise um mindestens 30 % und besonders vorteilhaft um zumindest 50 % elastisch veränderbar ist, und das insbesondere eine von einer Veränderung der Erstreckung abhängige und vorzugsweise zu der Veränderung proportionale Gegenkraft erzeugt, die der Veränderung entgegen wirkt. Unter einer "Erstreckung" eines Elements soll insbesondere ein maximaler Abstand zweier Punkte einer senkrechten Projektion des Elements auf eine Ebene verstanden werden. Vorzugsweise ist das zumindest eine Federelement als eine Schraubenfeder, insbesondere als eine gewundene Torsionsfeder, insbesondere als eine Druckfeder, ausgebildet.Preferably, the actuator unit is designed as a particular electrical and / or electromagnetic and / or pneumatic and / or hydraulic unit, which is provided to generate at least one particular linear movement. Preferably, the control valve device has at least one valve tappet, which is provided to transmit a generated by the at least one actuator unit in particular linear movement on the at least one throttle element and to pivot and / or deform this and / or preferably in particular to move linearly. The at least one valve tappet is advantageously designed in one piece with the at least one throttle element. By "in one piece" is intended to be connected in particular at least materially, for example by a Welding process and / or bonding process, etc., and be understood particularly advantageous molded, such as by the production of a cast and / or by the production in a one- or multi-component injection molding process. By pivoting and / or deforming and / or preferably a method of the at least one throttle element relative to the at least one valve seat, at least one gap between the at least one throttle element and the at least one valve seat is enlarged and / or minimized and / or at least substantially complete closable. A "spring element" is to be understood in particular to be an element which has at least one extension which in a normal operating state can be elastically changed by at least 10%, in particular by at least 20%, preferably by at least 30% and particularly advantageously by at least 50%, and which in particular produces a counterforce dependent on a change in extension and preferably proportional to the change, which counteracts the change. An "extension" of an element should, in particular, be understood to mean a maximum distance between two points of a vertical projection of the element onto a plane. Preferably, the at least one spring element is designed as a helical spring, in particular as a helical torsion spring, in particular as a compression spring.

Darunter, dass das zumindest eine Federelement das zumindest eine Drosselelement mit einer zumindest im Wesentlichen in Richtung des zumindest einen Ventilsitzes gerichteten Kraft beaufschlagt, soll insbesondere verstanden werden, dass das zumindest eine Drosselelement in zumindest einen Betriebszustand insbesondere durch eine Federkraft, von zumindest 1 N, vorteilhaft von zumindest 1,5 N, besonders vorteilhaft von zumindest 2 N und vorzugsweise von zumindest 2,5 N des zumindest einen Federelements in Richtung des zumindest einen Ventilsitzes gedrückt wird. Das zumindest eine Federelement ist insbesondere dazu vorgesehen, das zumindest eine Drosselelement insbesondere bei deaktivierter und/oder ausgefallener Aktoreinheit in eine Schließposition zu bewegen und/oder zu verformen und/oder in der Schließposition zu halten. Unter einer "Schließposition" soll insbesondere eine Position verstanden werden, in welcher das zumindest eine Drosselelement in unmittelbarem Kontakt zu dem zumindest einen Ventilsitz steht und ein Spalt zwischen dem zumindest einen Drosselelement und dem zumindest einen Ventilsitz zumindest im Wesentlichen vollständig verschwindet und/oder geschlossen ist. Insbesondere ist eine Verbindung zwischen dem zumindest einen Drosselelement und dem zumindest einen Ventilsitz in der Schließposition zumindest im Wesentlichen gasdicht. Unter "zumindest im Wesentlichen gasdicht" soll in diesem Zusammenhang insbesondere verstanden werden, dass ein Dichtbereich zwischen dem zumindest einen Drosselelement und dem zumindest einen Ventilsitz eine Leckrate von maximal 10-6 Pa*m3/s, vorteilhaft von maximal 10-8 Pa*m3/s und vorzugsweise von maximal 10-10 Pa*m3/s aufweist. Insbe-sondere weist das zumindest eine Federelement in einem montierten Zustand eine Vorspannung auf. Eine vorgespannte Länge des zumindest einen Federelements, insbesondere in der Schließposition des zumindest einen Drosselelements, beträgt insbesondere, maximal 75 %, vorteilhaft maximal 50 %, besonders vorteilhaft maximal 25 % und vorzugsweise maximal 12,5 % einer ungespannten Länge des zumindest einen Federelements. Abhängig von einer Verfahrrichtung des zumindest einen Drosselelements arbeitet die zumindest eine Aktoreinheit insbesondere mit oder gegen die Federkraft des zumindest einen Federelements.By the fact that the at least one spring element acts on the at least one throttle element with a force directed at least substantially in the direction of the at least one valve seat, should be understood in particular that the at least one throttle element in at least one operating state, in particular by a spring force of at least 1 N, advantageously of at least 1.5 N, particularly advantageously of at least 2 N and preferably of at least 2.5 N of the at least one spring element in the direction of the at least one valve seat is pressed. The at least one spring element is provided in particular for moving and / or deforming the at least one throttle element, in particular when the actuator unit is deactivated and / or has failed, and / or to hold it in the closed position. A "closing position" should be understood in particular a position in which the at least one throttle element is in direct contact with the at least one valve seat and a gap between the at least one throttle element and the at least one valve seat at least substantially completely disappears and / or closed , In particular, one is Connection between the at least one throttle element and the at least one valve seat in the closed position at least substantially gas-tight. By "at least substantially gas-tight" is to be understood in this context, in particular, that a sealing area between the at least one throttle element and the at least one valve seat has a leak rate of at most 10 -6 Pa * m 3 / s, advantageously of at most 10 -8 Pa * m 3 / s and preferably of at most 10 -10 Pa * m 3 / s. In particular, the at least one spring element has a prestress in an assembled state. A prestressed length of the at least one spring element, in particular in the closed position of the at least one throttle element, is in particular at most 75%, advantageously at most 50%, particularly advantageously at most 25% and preferably at most 12.5% of an unstressed length of the at least one spring element. Depending on a direction of travel of the at least one throttle element, the at least one actuator unit operates in particular with or against the spring force of the at least one spring element.

Durch eine derartige Ausgestaltung kann eine gattungsgemäße Regelventilvorrichtung mit verbesserten Betriebseigenschaften bereitgestellt werden. Insbesondere kann durch eine Verwendung eines Federelements mit einer relativ geringen Federkonstante eine vorteilhaft geringe Änderung der Federkraft des Federelements bei einem Verfahren des zumindest einen Drosselelements erreicht werden. Somit kann ein vorteilhaft exaktes Verfahren des zumindest einen Drosselelements relativ zu dem zumindest einen Ventilsitz erfolgen. Ferner kann durch das zumindest eine Federelement eine vorteilhafte Dichtheit, insbesondere Gasdichtheit, der Regelventilvorrichtung in einem geschlossenen Zustand erreicht werden.By such a configuration, a generic control valve device can be provided with improved operating characteristics. In particular, by using a spring element with a relatively small spring constant, an advantageously small change in the spring force of the spring element can be achieved in a method of the at least one throttle element. Thus, an advantageous exact method of the at least one throttle element relative to the at least one valve seat can be carried out. Furthermore, an advantageous tightness, in particular gas tightness, of the control valve device in a closed state can be achieved by the at least one spring element.

Ferner wird vorgeschlagen, dass die zumindest eine Aktoreinheit als eine Tauchspulenaktoreinheit ausgebildet ist. Unter einer "Tauchspulenaktoreinheit" soll in diesem Zusammenhang insbesondere eine Aktoreinheit verstanden werden, welche zumindest einen Primärteil und zumindest einen zu dem zumindest einen Primärteil beweglich gelagerten Sekundärteil aufweist. Der zumindest eine Primärteil umfasst insbesondere zumindest einen Magnetkreis mit zumindest einem Dauermagneten. Der Sekundärteil umfasst insbesondere zumindest eine Spule, welche in einem Luftspalt des Magnetkreises des Primärteils angeordnet ist. Der Primärteil ist insbesondere vorzugsweise mechanisch fixiert. Bei einer Beaufschlagung der zumindest einen Spule des zumindest einen Sekundärteils innerhalb eines Magnetfelds des Primärteils mit einem Strom wirkt auf die Spule und somit auf den Sekundärteil eine Lorentzkraft, die den Sekundärteil entlang des Primärteils verlagert. Die Kraft ist dabei insbesondere proportional zum Strom. Eine Richtung des Kraftvektors wird dabei insbesondere von der Stromrichtung bestimmt. Hierdurch kann eine Aktoreinheit bereitgestellt werden, welche vorteilhaft ein bidirektionales Verformen und/oder Verschwenken und/oder vorzugsweise Verfahren der zumindest einen Drosseleinheit ermöglicht. Ferner kann eine vorteilhaft exakte Verformung und/oder Verschwenkung und/oder Positionierung der zumindest einen Drosseleinheit erreicht werden.It is also proposed that the at least one actuator unit is designed as a Tauchspulenaktoreinheit. A "Tauchspulenaktoreinheit" should be understood in this context, in particular an actuator, which has at least one primary part and at least one movable to the at least one primary part secondary part. The at least one primary part comprises in particular at least one magnetic circuit with at least one permanent magnet. In particular, the secondary part comprises at least one coil, which is arranged in an air gap of the magnetic circuit of the primary part. The primary part is in particular preferably mechanically fixed. Upon application of the at least one coil of the at least one secondary part within a magnetic field of the primary part a current acts on the coil and thus on the secondary part a Lorentz force that displaces the secondary part along the primary part. The force is particularly proportional to the current. A direction of the force vector is determined in particular by the current direction. In this way, an actuator unit can be provided, which advantageously allows a bidirectional deformation and / or pivoting and / or preferably a method of the at least one throttle unit. Furthermore, an advantageous exact deformation and / or pivoting and / or positioning of the at least one throttle unit can be achieved.

Vorteilhaft weist der zumindest eine Ventilstößel gegenüber aus dem Stand der Technik bekannten Ventilstößeln eine reduzierte Masse auf. Insbesondere kann der zumindest eine Ventilstößel zumindest teilweise von einem Leichtbaumaterial, beispielsweise Aluminium und/oder einem Kunststoff und/oder einem faserverstärkten Kunststoff, insbesondere einem glasfaserverstärkten Kunststoff, gebildet sein. Vorzugsweise weist der zumindest einen Ventilstößel jedoch zumindest eine massereduzierende Ausnehmung auf. Vorzugsweise ist der zumindest eine Ventilstößel zumindest teilweise hohl ausgebildet. Alternativ ist ebenso denkbar, dass der zumindest eine Ventilstößel zumindest teilweise eine Skelett- und/oder Gitterstruktur mit einer Mehrzahl von Ausnehmungen aufweist. Hierdurch kann eine Trägheit des zumindest einen Ventilstößels vorteilhaft reduziert werden. Ferner kann eine zu einem Verformen und/oder Verschwenken und/oder Verfahren des zumindest einen Drosselelements benötigte Kraft vorteilhaft reduziert werden.The at least one valve tappet advantageously has a reduced mass relative to valve tappets known from the prior art. In particular, the at least one valve tappet may be at least partially formed by a lightweight construction material, for example aluminum and / or a plastic and / or a fiber-reinforced plastic, in particular a glass-fiber-reinforced plastic. However, the at least one valve tappet preferably has at least one mass-reducing recess. Preferably, the at least one valve tappet is at least partially hollow. Alternatively, it is also conceivable that the at least one valve stem has at least partially a skeleton and / or lattice structure with a plurality of recesses. As a result, an inertia of the at least one valve tappet can be advantageously reduced. Furthermore, a force required for deforming and / or pivoting and / or moving the at least one throttle element can advantageously be reduced.

Des Weiteren wird vorgeschlagen, dass die Regelventilvorrichtung zumindest ein Linearlager umfasst, welches zu einer insbesondere mittelbaren Führung des zumindest einen Drosselelements, insbesondere mittels des zumindest einen Ventilstößels, vorgesehen ist. Das zumindest eine Linearlager ist insbesondere zu einer Führung des zumindest einen Ventilstößels vorgesehen. Unter einem "Linearlager" soll in diesem Zusammenhang insbesondere ein Lager verstanden werden, welches den zumindest einen Ventilstößel in Umfangsrichtung zumindest teilweise und vorzugsweise zumindest zu einem Großteil umschließt. Unter dem Ausdruck "zumindest zu einem Großteil" soll dabei zumindest 50 %, vorteilhaft zumindest 60 %, vorzugsweise zumindest 70 % und besonders bevorzugt zumindest 80 % verstanden werden. Unter einer "Umfangsrichtung" eines Objekts soll insbesondere eine azimutale, senkrecht zu einer Längserstreckungsrichtung des Objekts angeordnete Richtung verstanden werden. Unter einer "Längserstreckungsrichtung" eines Objekts soll insbesondere eine Richtung verstanden werden, welche parallel ist zu einer längsten Kante eines kleinsten gedachten Quaders, welcher das Objekt gerade noch umgibt. Insbesondere kann das zumindest eine Linearlager als ein Lineargleitlager ausgebildet sein, dessen Oberfläche insbesondere einen Mittenrauwert von maximal 0,2 µm, vorteilhaft von maximal 0,1 µm und vorzugsweise von maximal 0,05 µm aufweist. Insbesondere kann der Mittenrauwert durch eine Oberflächenbearbeitung und oder durch eine Beschichtung der Oberfläche des Lineargleitlagers, beispielsweise mit PTFE und/oder einem Kunststoff, erreicht werden. Alternativ kann das zumindest eine Linearlager als ein Linearkugellager ausgebildet sein. Hierdurch kann eine vorteilhaft exakte Führung des zumindest einen Ventilstößels bei gleichzeitig vorteilhaft reduzierter Reibung erreicht werden, insbesondere zur Kompensation einer relativ geringen Seitenstabilität des zumindest einen Federelements. Somit kann eine zu einem Verformen und/oder Verschwenken und/oder Verfahren des zumindest einen Drosselelements benötigte Kraft vorteilhaft reduziert und eine Positioniergenauigkeit des zumindest einen Drosselelements vorteilhaft gesteigert werden.Furthermore, it is proposed that the control valve device comprises at least one linear bearing which is provided for a particular indirect guidance of the at least one throttle element, in particular by means of the at least one valve tappet. The at least one linear bearing is provided in particular for guiding the at least one valve tappet. A "linear bearing" is to be understood in this context, in particular a bearing which surrounds the at least one valve stem in the circumferential direction at least partially, and preferably at least a large part. The term "at least to a large extent" should be understood to mean at least 50%, advantageously at least 60%, preferably at least 70% and particularly preferably at least 80%. A "circumferential direction" of an object is intended in particular to be an azimuthal, perpendicular to a direction of longitudinal extent of the object Object arranged direction to be understood. A "longitudinal extension direction" of an object should in particular be understood to mean a direction which is parallel to a longest edge of a smallest imaginary cuboid which just barely surrounds the object. In particular, the at least one linear bearing may be formed as a linear sliding bearing whose surface has, in particular, a center roughness of not more than 0.2 μm, advantageously of not more than 0.1 μm and preferably of not more than 0.05 μm. In particular, the average roughness value can be achieved by a surface treatment and / or by a coating of the surface of the linear sliding bearing, for example with PTFE and / or a plastic. Alternatively, the at least one linear bearing may be formed as a linear ball bearing. In this way, an advantageously exact guidance of the at least one valve tappet can be achieved with simultaneously advantageously reduced friction, in particular for compensation of a relatively low lateral stability of the at least one spring element. Thus, a force required for deforming and / or pivoting and / or moving the at least one throttle element can advantageously be reduced and a positioning accuracy of the at least one throttle element advantageously increased.

Ferner wird vorgeschlagen, dass die Regelventilvorrichtung zumindest ein Dichtelement umfasst, welches zwischen dem zumindest einen Drosselelement und dem zumindest einen Ventilsitz angeordnet ist. Das zumindest eine Dichtelement kann dabei an dem zumindest einen Ventilsitz, insbesondere an der Anlagefläche des zumindest einen Ventilsitzes, und/oder vorzugsweise an dem zumindest einen Drosselelement, insbesondere in Umfangsrichtung umlaufend an dem zumindest einen Drosselelement, angeordnet sein. Unter einem "Dichtelement" soll in diesem Zusammenhang insbesondere ein Element verstanden werden, welches dazu vorgesehen ist, einen insbesondere ungewollten Austritt zumindest eines Fluids aus einer Ventilkammer der Regelventilvorrichtung zu begrenzen und/oder zumindest zu einem Großteil zu verhindern. Insbesondere kann das zumindest eine Dichtelement zumindest teilweise aus einem Elastomer, beispielsweise Polyurethan und/oder Nitrilkautschuk, bestehen. Hierdurch kann eine vorteilhaft verbesserte Dichtwirkung erreicht werden, insbesondere auch bei einer Beaufschlagung des zumindest einen Drosselelements mit einer relativ geringen Kraft, insbesondere durch das zumindest einen Federelement.It is also proposed that the control valve device comprises at least one sealing element, which is arranged between the at least one throttle element and the at least one valve seat. The at least one sealing element can be arranged on the at least one valve seat, in particular on the contact surface of the at least one valve seat, and / or preferably on the at least one throttle element, in particular circumferentially on the at least one throttle element. In this context, a "sealing element" is to be understood as meaning, in particular, an element which is intended to limit, and / or at least to largely prevent, a particularly undesired escape of at least one fluid from a valve chamber of the control valve device. In particular, the at least one sealing element may at least partially consist of an elastomer, for example polyurethane and / or nitrile rubber. In this way, an advantageously improved sealing effect can be achieved, in particular also when the at least one throttle element is acted upon by a relatively small force, in particular by the at least one spring element.

Ist der zumindest eine Ventilsitz zumindest teilweise keilförmig ausgebildet, kann eine Dichtwirkung vorteilhaft weiter verbessert werden. Darunter, dass der zumindest eine Ventilsitz zumindest teilweise "keilförmig" ausgebildet ist, soll insbesondere verstanden werden, dass sich der zumindest eine Ventilsitz ausgehend von einer Ventilsitzbasis zu einem in Richtung des zumindest einen Drosselelements weisenden Ende hin verjüngt.If the at least one valve seat is at least partially wedge-shaped, a sealing effect can advantageously be further improved. The fact that the at least one valve seat is at least partially "wedge-shaped" should in particular mean that the at least one valve seat tapers from a valve seat base to an end pointing in the direction of the at least one throttle element.

Des Weiteren wird vorgeschlagen, dass die Regelventilvorrichtung zumindest eine Membran umfasst, welche dazu vorgesehen ist, zumindest eine Ventilkammer zumindest einseitig abzuschließen. Unter einer "Membran" soll in diesem Zusammenhang eine insbesondere flexible gasdichte Trennschicht, insbesondere Wellbalg- und/oder vorzugsweise Polymertrennschicht, verstanden werden. Unter einer "Ventilkammer" soll in diesem Zusammenhang insbesondere ein räumlicher Bereich innerhalb der Regelventilvorrichtung verstanden werden, in welche zumindest ein Fluid einleitbar ist. Insbesondere wird die zumindest eine Ventilkammer durch die zumindest eine Membran an einer dem zumindest einen Drosselelement gegenüberliegenden Seite in jedem Betriebszustand zumindest im Wesentlichen gasdicht abgeschlossen. Insbesondere ist die zumindest eine Membran mit einem äußeren Umfang an einer Wandung der zumindest einen Ventilkammer befestigt. Insbesondere ist die zumindest eine Membran mit einem inneren Umfang an dem zumindest einen Ventilstößel befestigt. Hierdurch kann eine Ventilkammer vorteilhaft abgeschlossen werden, insbesondere auch während einer linearen Bewegung des zumindest einen Ventilstößels.Furthermore, it is proposed that the control valve device comprises at least one membrane which is provided to terminate at least one valve chamber at least on one side. In this context, a "membrane" is to be understood as meaning in particular a flexible, gas-tight separating layer, in particular corrugated bellows and / or preferably polymer separating layer. In this context, a "valve chamber" is to be understood as meaning, in particular, a spatial area within the control valve device into which at least one fluid can be introduced. In particular, the at least one valve chamber is closed by the at least one membrane on at least one throttle element opposite side in each operating state at least substantially gas-tight. In particular, the at least one membrane is fastened with an outer circumference to a wall of the at least one valve chamber. In particular, the at least one membrane with an inner circumference is attached to the at least one valve tappet. As a result, a valve chamber can be advantageously closed, in particular also during a linear movement of the at least one valve tappet.

Vorzugsweise entspricht ein effektiver Flächeninhalt einer der zumindest einen Ventilkammer zugwandten Oberfläche der zumindest einen Membran zumindest im Wesentlichen einem effektiven Flächeninhalt einer der zumindest einen Ventilkammer zugwandten Oberfläche des zumindest einen Drosselelements. Insbesondere weicht ein effektiver Flächeninhalt einer der zumindest einen Ventilkammer zugwandten Oberfläche der zumindest einen Membran um maximal 10 %, vorteilhaft um maximal 8 %, besonders vorteilhaft um maximal 5 % und vorzugsweise um maximal 2 % von einem effektiven Flächeninhalt einer der zumindest einen Ventilkammer zugwandten Oberfläche des zumindest einen Drosselelements ab. Unter einem "effektiven Flächeninhalt" soll in diesem Zusammenhang insbesondere ein Flächeneinhalt eines Elements verstanden werden, welcher durch ein in die zumindest eine Ventilkammer einströmendes Fluid mit einem Druck beaufschlagt wird. Hierdurch kann eine Differenz zwischen einer durch ein in die zumindest eine Ventilkammer einströmendes Fluid auf die zumindest eine Membran wirkenden Kraft und einer durch das einströmende Fluid auf das zumindest eine Drosselelement wirkenden Kraft vorteilhaft reduziert werden. Somit kann ein Einfluss der durch ein in die zumindest eine Ventilkammer einströmendes Fluid erzeugten Kräfte auf einen Regelungsvorgang vorteilhaft minimiert werden.Preferably, an effective surface area of a surface of the at least one membrane facing the at least one valve chamber corresponds at least substantially to an effective surface area of a surface of the at least one throttle element facing the at least one valve chamber. In particular, an effective surface area of a surface of the at least one membrane facing the at least one valve chamber deviates by at most 10%, advantageously by not more than 8%, particularly advantageously by not more than 5% and preferably by not more than 2% from an effective surface area of a surface facing the at least one valve chamber of the at least one throttle element. In this context, an "effective surface area" is to be understood as meaning, in particular, a surface area of an element which is subjected to a pressure by a fluid flowing into the at least one valve chamber. This can be a difference a force acting on the at least one membrane by a fluid flowing into the at least one valve chamber and a force acting on the at least one throttle element by the inflowing fluid are advantageously reduced. Thus, an influence of the forces generated by a fluid flowing into the at least one valve chamber can advantageously be minimized to a control process.

Ferner wird ein Ventilsystem mit zumindest einer erfindungsgemäßen Regelventilvorrichtung vorgeschlagen mit zumindest einer weiteren Ventilvorrichtung, welche mit der zumindest einen Regelventilvorrichtung fluidtechnisch in Reihe geschaltet ist. Hierdurch kann auf vorteilhaft einfache Weise eine Verschaltung der zumindest einen Regelventilvorrichtung mit weiteren Ventilvorrichtungen, insbesondere mit gleicher oder verschiedener Funktion, ermöglicht werden. Ferner kann ein vorteilhaftes Anpassen eines Ventilsystems erfolgen.Furthermore, a valve system with at least one control valve device according to the invention is proposed with at least one further valve device, which is connected in fluidic connection with the at least one control valve device in series. As a result, an interconnection of the at least one control valve device with further valve devices, in particular with the same or different function, can be made possible in an advantageously simple manner. Furthermore, an advantageous adaptation of a valve system can take place.

Vorzugsweise ist die zumindest eine weitere Ventilvorrichtung als Absperrventil ausgebildet. Unter einem "Absperrventil" soll in diesem Zusammenhang insbesondere ein Ventil verstanden werden, welches zu einem insbesondere kontrollierten Öffnen und/oder Schließen zumindest einer Fluidleitung vorgesehen ist. Vorzugsweise ist das zumindest eine Absperrventil als ein Solenoidventil ausgebildet. Hierdurch kann auf vorteilhaft einfache Weise eine Durchleitung zumindest eines Fluids zugelassen und/oder verhindert werden.Preferably, the at least one further valve device is designed as a shut-off valve. In this context, a "shut-off valve" should be understood to mean, in particular, a valve which is provided for a particularly controlled opening and / or closing of at least one fluid line. Preferably, the at least one shut-off valve is designed as a solenoid valve. As a result, a passage of at least one fluid can be admitted and / or prevented in an advantageously simple manner.

Die erfindungsgemäße Regelventilvorrichtung soll hierbei nicht auf die oben beschriebene Anwendung und Ausführungsform beschränkt sein. Insbesondere kann die erfindungsgemäße Brennstoffzellenvorrichtung zu einer Erfüllung einer hierin beschriebenen Funktionsweise eine von einer hierin genannten Anzahl von einzelnen Elementen, Bauteilen und Einheiten abweichende Anzahl aufweisen.The control valve device according to the invention should not be limited to the application and embodiment described above. In particular, the fuel cell device according to the invention may have a different number from a number of individual elements, components and units mentioned herein for fulfilling a mode of operation described herein.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Figur 1 zeigt eine Schnittdarstellung eines Ventilsystems 40 mit einer Regelventilvorrichtung 10 und einer weiteren Ventilvorrichtung 36. Die Regelventilvorrichtung 10 und die weitere Ventilvorrichtung 36 sind fluidtechnisch in Reihe geschaltet. Die weitere Ventilvorrichtung 36 ist der Regelventilvorrichtung 10 fluidtechnisch vorgeschaltet. Das Ventilsystem 40 weist eine Einlassöffnung 50 auf, welche zu einer Einleitung eines, insbesondere gasförmigen, Fluids in das Ventilsystem 40 vorgesehen ist. Ferner weist das Ventilsystem 40 eine Auslassöffnung 52 auf, welche zu einer Ausleitung des Fluids aus dem Ventilsystem 40 vorgesehen ist. An der Einlassöffnung 50 und die Auslassöffnung 52 ist jeweils ein Gewindeflansch 54, 56 angeordnet, welches zu einem Anschluss einer nicht dargestellten Fluidzuleitung und/oder einer nicht dargestellten Fluidableitung vorgesehen sind. FIG. 1 shows a sectional view of a valve system 40 with a control valve device 10 and a further valve device 36. The control valve device 10 and the further valve device 36 are fluidly connected in series. The further valve device 36 is upstream of the control valve device 10 in terms of fluid technology. The valve system 40 has an inlet opening 50, which is provided for introducing a, in particular gaseous, fluid into the valve system 40. Furthermore, the valve system 40 has an outlet opening 52, which is provided for a discharge of the fluid from the valve system 40. At the inlet opening 50 and the outlet opening 52, a threaded flange 54, 56 is respectively arranged, which are provided to a connection of a fluid supply line, not shown, and / or a fluid discharge, not shown.

Die weitere Ventilvorrichtung 36 ist als ein Absperrventil 38 ausgebildet. Die weitere Ventilvorrichtung 36 ist als ein Solenoidventil 42 ausgebildet. Alternativ ist es jedoch ebenso denkbar, dass eine weitere Ventilvorrichtung als ein Hydraulikventil und/oder ein Pneumatikventil und/oder ein manuelles Ventil ausgebildet ist. Die weitere Ventilvorrichtung 36 weist eine elektromagnetische Aktoreinheit 46 auf. Die Aktoreinheit 46 umfasst eine Spule 60, welche mechanisch in ihrer Position fixiert ist. Ferner umfasst die Aktoreinheit 46 einen Kern 62 aus einem ferromagnetischen Material, beispielsweise Eisen oder Stahl. Der Kern 62 ist linear beweglich innerhalb der Spule 60 gelagert. Ein Absperrelement 48 der weiteren Ventilvorrichtung 36 ist über einen Ventilstößel 64 mit dem Kern 62 verbunden. Des Weiteren umfasst die Aktoreinheit 46 ein als eine Druckfeder ausgebildetes Federelement 66, welches dazu vorgesehen ist, das Absperrelement 48 in einem unbestromten Zustand der Aktoreinheit 46 in Richtung eines Ventilsitzes 58 der weiteren Ventilvorrichtung 36 zu drücken und die weitere Ventilvorrichtung 36 somit zu schließen. Das Federelement 66 ist dazu auf einer dem Absperrelement 48 abgewandten Seite des Kerns 62 zwischen dem Kern 62 und einem Gehäuse 68 des Ventilsystems 40 und/oder der weiteren Ventilvorrichtung 36 angeordnet. Durch eine Bestromung der Aktoreinheit 46 ist der Kern 62 linear gegen eine Federkraft des Federelements 66 bewegbar. Durch die lineare Bewegung des Kerns 62 gegen die Federkraft des Federelements 66 erfolgt ein Abheben des Absperrelements 48 von dem Ventilsitz 58, wodurch die weitere Ventilvorrichtung 36 geöffnet wird.The further valve device 36 is designed as a shut-off valve 38. The further valve device 36 is designed as a solenoid valve 42. Alternatively, however, it is also conceivable that a further valve device is designed as a hydraulic valve and / or a pneumatic valve and / or a manual valve. The further valve device 36 has an electromagnetic actuator unit 46. The actuator unit 46 comprises a coil 60 which is mechanically fixed in position. Furthermore, the actuator unit 46 comprises a core 62 made of a ferromagnetic material, for example iron or steel. The core 62 is mounted linearly movable within the coil 60. A shut-off element 48 of the further valve device 36 is connected to the core 62 via a valve tappet 64. Furthermore, the actuator unit 46 comprises a spring element 66 designed as a compression spring, which is provided for locking the shut-off element 48 in a currentless state of the actuator unit 46 in the direction of a valve seat 58 of the further valve device to press 36 and the other valve device 36 thus close. For this purpose, the spring element 66 is arranged on a side of the core 62 facing away from the shut-off element 48 between the core 62 and a housing 68 of the valve system 40 and / or the further valve device 36. By energizing the actuator 46, the core 62 is linearly movable against a spring force of the spring element 66. Due to the linear movement of the core 62 against the spring force of the spring element 66, a lifting of the shut-off element 48 from the valve seat 58, whereby the further valve device 36 is opened.

Bei geöffneter weiterer Ventilvorrichtung 36 strömt das durch die Einlassöffnung 50 in das Ventilsystem 40 eingeleitete Fluid in eine Ventilkammer 30 der Regelventilvorrichtung 10. Die Regelventilvorrichtung 10 umfasst ein Drosselelement 12, einen Ventilsitz 14 sowie eine Aktoreinheit 16, welche dazu vorgesehen ist, das zumindest eine Drosselelement 12 relativ zu dem Ventilsitz 14 zu verfahren. Die Aktoreinheit 16 ist als eine Tauchspulenaktoreinheit 20 ausgebildet. Die Aktoreinheit 16 umfasst einen dauermagnetischen Kern 70, welcher mechanisch in seiner Position fixiert ist. Ferner umfasst die Aktoreinheit 16 eine Spule 72, welche auf einen relativ zu dem Kern 70 beweglichen Spulenträger 74 gewickelt ist. Bei einer Beaufschlagung der zumindest einen Spule 72 mit einem Strom, wirkt auf die Spule 72 und somit auf den Spulenträger 74 eine Lorentzkraft, die den Spulenträger 74 entlang des Kerns 70 verlagert. Die Kraft ist dabei proportional zu einer Stromstärke. Eine Richtung des Kraftvektors ist insbesondere von einer Stromrichtung bestimmt. Ferner umfasst die Regelventilvorrichtung 10 einen Ventilstößel 22, welcher dazu vorgesehen ist, eine Bewegung des Spulenträgers 74 auf das Drosselelement 12 zu übertragen. Der Ventilstößel 22 ist teilweise hohl ausgebildet und weist eine entlang seiner Haupterstreckung verlaufende Ausnehmung 24 auf, wodurch eine Masse und somit eine Trägheit des Ventilstößels 22 gegenüber einem Ventilstößel aus einem Vollmaterial reduziert ist. Der Ventilstößel 22 ist einstückig mit dem Drosselelement 12 ausgebildet. Das Drosselelement 12 ist zumindest im Wesentlichen tellerförmig ausgebildet. An dem Drosselelement 12 ist in Umfangrichtung umlaufend ein, insbesondere elastisches, Dichtelement 26 angeordnet.When the further valve device 36 is open, the fluid introduced into the valve system 40 through the inlet opening 50 flows into a valve chamber 30 of the control valve device 10. The control valve device 10 comprises a throttle element 12, a valve seat 14 and an actuator unit 16 which is provided with the at least one throttle element 12 relative to the valve seat 14 to proceed. The actuator unit 16 is designed as a Tauchspulenaktoreinheit 20. The actuator unit 16 comprises a permanent magnetic core 70, which is mechanically fixed in its position. Furthermore, the actuator unit 16 comprises a coil 72, which is wound on a relative to the core 70 movable coil carrier 74. When the at least one coil 72 is subjected to a current, a Lorentz force acts on the coil 72 and thus on the coil carrier 74, displacing the coil carrier 74 along the core 70. The force is proportional to a current strength. A direction of the force vector is determined in particular by a current direction. Furthermore, the control valve device 10 comprises a valve tappet 22 which is provided to transmit a movement of the coil carrier 74 to the throttle element 12. The valve stem 22 is partially hollow and has a recess extending along its main extension recess 24, whereby a mass and thus an inertia of the valve stem 22 relative to a valve stem of a solid material is reduced. The valve stem 22 is formed integrally with the throttle element 12. The throttle element 12 is at least substantially plate-shaped. On the throttle element 12 circumferentially one, in particular elastic, sealing element 26 is arranged circumferentially.

Die Ventilkammer 30 ist an einer zu der Aktoreinheit 16 gewandten Seite durch eine flexible Membran 28 abgeschlossen. Die Membran 28 ist mit einem äußeren Umfang 78 an einer Wandung 82 der Ventilkammer 30 befestigt. Mit einem inneren Umfang 80 ist die Membran 28 an dem Ventilstößel 22 befestigt. Bewegungen des Ventilstößels 22 führen zu einer entsprechenden Auslenkung der Membran 28, wodurch die Ventilkammer 30 auch bei Bewegungen des Ventilstößels 22 zuverlässig in Richtung der Aktoreinheit 16 abgeschlossen ist. Ein effektiver Flächeninhalt einer der Ventilkammer 30 zugwandten Oberfläche 32 der einen Membran 28 entspricht einem effektiven Flächeninhalt einer der Ventilkammer 30 zugwandten Oberfläche 34 des einen Drosselelements 12. Hierdurch tritt keine Differenz zwischen einer durch ein in die Ventilkammer 30 einströmendes Fluid auf die Membran 28 wirkenden Kraft und einer durch das einströmende Fluid auf das Drosselelement 12 wirkenden Kraft auf. Ein Einfluss durch ein in die Ventilkammer 30 einströmenden Fluids erzeugter Kräfte auf ein Öffnen und/oder Schließen der Regelventilvorrichtung 10 ist somit eliminiert. Eine der Aktoreinheit 16 zugewandten Oberfläche 92 der Membran 28 ist mit einem Referenzdruck, beispielsweise einem Umgebungsluftdruck, beaufschlagt.The valve chamber 30 is closed by a flexible membrane 28 on a side facing the actuator unit 16. The membrane 28 is attached to an outer periphery 78 on a wall 82 of the valve chamber 30. With an inner periphery 80, the diaphragm 28 is secured to the valve lifter 22. Movements of the valve lifter 22 lead to a corresponding deflection of the diaphragm 28, as a result of which the valve chamber 30 is reliably closed even in the case of movements of the valve tappet 22 in the direction of the actuator unit 16. An effective surface area of a surface 32 of the one diaphragm 28 facing the valve chamber 30 corresponds to an effective area of a surface 34 of the one throttle element 12 facing the valve chamber 30. As a result, no difference occurs between a force acting on the diaphragm 28 by a fluid flowing into the valve chamber 30 and a force acting on the throttle element 12 by the inflowing fluid. An influence by forces generated by a fluid flowing into the valve chamber 30 on opening and / or closing of the control valve device 10 is thus eliminated. One of the actuator unit 16 facing surface 92 of the membrane 28 is subjected to a reference pressure, for example, an ambient air pressure.

Des Weiteren umfasst die Regelventilvorrichtung 10 ein Federelement 18, welches dazu vorgesehen ist, das Drosselelement 12 mit einer in Richtung des Ventilsitzes 14 gerichteten Kraft zu beaufschlagen. In einem geschlossenen Zustand der Regelventilvorrichtung 10 ist das Drosselelement 12 durch das Federelement 18 beispielsweise mit einer Kraft von 1 N bis 2,5 N beaufschlagt. Das Federelement 18 ist zwischen dem Drosselelement 12 und dem Gehäuse 68 des Ventilsystems 40 und/oder der Regelventilvorrichtung 10 angeordnet. Das Federelement 18 ist unter einer Vorspannung montiert. Eine vorgespannte Länge des Federelements 18 in einem geschlossenen Zustand der Regelventilvorrichtung 10 beträgt beispielsweise ein Viertel einer ungespannten Länge des Federelements 18. Das Federelement 18 weist insbesondere eine Federkonstante von maximal 0,5 N/mm auf. Vorzugsweise weist das Federelement 18 eine Federkonstante von maximal 0,1 N/mm auf. Das Federelement 18 ist als eine Schraubendruckfeder 76 ausgebildet. Insbesondere bei deaktivierter und/oder ausgefallener Aktoreinheit 16 ist das Drosselelement 12 durch das Federelement 18 gegen den Ventilsitz 14 gedrückt, wodurch jederzeit, insbesondere bei einem Ausfall einer Stromversorgung der Regelventileinheit 10, ein sicheres, insbesondere gasdichtes, Schließen der Regelventilvorrichtung 10 gewährleistet ist. Um eine Dichtwirkung bei geschlossener Regelventilvorrichtung 10 weiter zu verbessern, ist der Ventilsitz 14 keilförmig ausgebildet. Der Ventilsitz 14 verjüngt sich ausgehend von einer Ventilsitzbasis 84 zu einem in Richtung des Drosselelements 12 weisenden Ende 86 hin. Hierdurch ist eine Anlagefläche zwischen dem Dichtelement 26 und dem Ventilsitz 14 in einem geschlossenen Zustand der Regelventilvorrichtung 10 reduziert und ein durch das Federelement 18 erzeugter Anpressdruck ist auf die relativ geringe Anlagefläche konzentriert.Furthermore, the control valve device 10 comprises a spring element 18, which is provided to pressurize the throttle element 12 with a force directed in the direction of the valve seat 14. In a closed state of the control valve device 10, the throttle element 12 is acted upon by the spring element 18, for example with a force of 1 N to 2.5 N. The spring element 18 is arranged between the throttle element 12 and the housing 68 of the valve system 40 and / or the control valve device 10. The spring element 18 is mounted under a bias. A prestressed length of the spring element 18 in a closed state of the control valve device 10 is for example a quarter of an unstressed length of the spring element 18. The spring element 18 has in particular a spring constant of at most 0.5 N / mm. Preferably, the spring element 18 has a spring constant of at most 0.1 N / mm. The spring element 18 is designed as a helical compression spring 76. In particular, when deactivated and / or failed actuator 16, the throttle element 12 is pressed by the spring member 18 against the valve seat 14, which at any time, especially in case of failure of a power supply of the control valve unit 10, a safe, in particular gas-tight, closing the control valve device 10 is guaranteed. In order to further improve a sealing effect in the closed control valve device 10, the valve seat 14 is wedge-shaped. The valve seat 14 tapers from a valve seat base 84 towards an end 86 pointing in the direction of the throttle element 12. As a result, a contact surface between the sealing element 26 and the valve seat 14 is reduced in a closed state of the control valve device 10 and a by the spring element 18 generated contact pressure is concentrated on the relatively small contact surface.

Zu einem Öffnen und/oder Schließen der Regelventilvorrichtung 10 wird die Spule 72 mit einem Strom beaufschlagt, wodurch eine lineare Bewegung des Spulenträgers 74 relativ zu dem Kern 70 erzeugt wird. Die Bewegung wird über den Ventilstößel 22 auf das Drosselelement 12 übertragen. Bei einem Öffnen der Regelventilvorrichtung 10 wird das Drosselelement 12 entgegen der Federkraft des Federelements 18 von dem Ventilsitz 14 wegbewegt, sodass das Fluid aus der Ventilkammer 30 in Richtung der Auslassöffnung 52 strömen kann. Bei einem Schließen der Regelventilvorrichtung 10 wird das Drosselelement 12 mit der Federkraft des Federelements 18 zu dem Ventilsitz 14 hinbewegt, sodass ein Volumenstrom des Fluids aus der Ventilkammer 30 in Richtung der Auslassöffnung 52 reduziert und in geschlossenem Zustand vollständig unterbunden wird. Der Ventilstößel 22 ist dabei durch ein Linearlager 44 geführt. Das Linearlager 44 ist als ein Gleitlager 88 ausgebildet. Zu einer Reduktion einer Reibung zwischen dem Ventilstößel 22 und dem Linearlager 44 weist eine Oberfläche 90 des Linearlagers 44 einen Mittenrauwert von maximal 0,1 µm auf. Die relativ geringe Federkonstante des Federelements 18 führt dazu, dass sich eine durch das Federelement 18 erzeugte und auf das Drosselelement 12 wirkende Kraft bei einer Längenänderung des Federelements 18 lediglich geringfügig verändert. Da eine durch die Aktoreinheit 16 erzeugte Kraft proportional zu einer Stromstärke eines Stroms ist, mit welchem die Spule 72 beaufschlagt wird, und sich eine durch das Federelement 18 erzeugte und auf das Drosselelement 12 wirkende Kraft bei einer Längenänderung des Federelements 18 lediglich geringfügig verändert, ist ein exaktes teilweises und/oder vollständiges Öffnen und/oder Schließen der Regelventilvorrichtung 10 möglich, da das Drosselelement 12 präzise in beliebige Positionen zwischen einem vollständigen Öffnen und einem vollständigen Schließen der Regelventilvorrichtung 10 verfahrbar ist.To open and / or close the control valve device 10, the coil 72 is supplied with a current, whereby a linear movement of the bobbin 74 is generated relative to the core 70. The movement is transmitted via the valve tappet 22 to the throttle element 12. Upon opening of the control valve device 10, the throttle element 12 is moved away from the valve seat 14 counter to the spring force of the spring element 18, so that the fluid can flow out of the valve chamber 30 in the direction of the outlet opening 52. When closing the control valve device 10, the throttle element 12 is moved with the spring force of the spring element 18 to the valve seat 14, so that a volume flow of the fluid from the valve chamber 30 is reduced in the direction of the outlet opening 52 and completely closed in the closed state. The valve stem 22 is guided by a linear bearing 44. The linear bearing 44 is formed as a sliding bearing 88. To reduce friction between the valve stem 22 and the linear bearing 44, a surface 90 of the linear bearing 44 has a center roughness of not more than 0.1 μm. The relatively small spring constant of the spring element 18 means that a force generated by the spring element 18 and acting on the throttle element 12 changes only slightly with a change in length of the spring element 18. Since a force generated by the actuator unit 16 is proportional to a current strength of a current, with which the coil 72 is acted upon, and a force generated by the spring member 18 and acting on the throttle element 12 force only slightly changed in a change in length of the spring element 18 is an exact partial and / or complete opening and / or closing of the control valve device 10 possible because the throttle element 12 can be moved precisely in any position between a complete opening and a complete closing of the control valve device 10.
