Definitions
- the present invention relates to a valve for closing a gas container, the valve comprising a valve body with a continuous longitudinal bore along a longitudinal axis, in which longitudinal bore a displaceably guided valve tappet is mounted, the valve body extending in a longitudinal direction parallel to the longitudinal axis from a connection area with a end surface on the connection side to a fastening area with an end surface on the gas container side, the fastening area having a smaller diameter than the connection area and the connection area having a stop surface in order to provide a stop for a base body head of the gas container when the fastening area is inserted through an opening in the base body head into the latter .
- Gas containers filled with gas can be connected in a gas-tight manner to a device, for example a soda siphon, a whipped cream siphon or a pressure regulator, in order to ensure a corresponding gas supply to the siphon or the device.
- a device for example a soda siphon, a whipped cream siphon or a pressure regulator, in order to ensure a corresponding gas supply to the siphon or the device.
- the EP 0 867 656 B1 a pressurized gas capsule with a valve body, the valve body being pressed to the gas container only via a simple groove, so that at high pressure there is a risk of the valve body being pushed out of the gas container.
- the valve body In order to limit the freedom of movement of a valve tappet that is mounted displaceably along a longitudinal axis in a continuous longitudinal bore, the valve body has projections that protrude radially inward only in a plane that is normal to the longitudinal axis, which, however, do not properly ensure a secure pressure-based movement or even retention of the valve tappet.
- valve according to the invention even at high pressure of the gas in the gas tank, protection should be ensured against the valve or a valve body of the valve being pushed out or pushed out of the gas tank, with preferably additionally a secured pressure-based movement and mounting of a displaceable valve in the valve body mounted valve tappet should be guaranteed.
- a valve for closing a gas container has a valve comprising a valve body with a continuous longitudinal bore along a longitudinal axis, in which longitudinal bore a displaceably guided valve tappet is mounted, the valve body extending in a longitudinal direction parallel to the longitudinal axis from a connection area with an end face on the connection side to a fastening area with an end face on the gas container side, the fastening area having a smaller diameter than the connection area and the connection area having a stop surface in order to provide a stop for a base body head of the gas container when the fastening area passes through an opening in the base body head is inserted into this, according to the invention that the valve body has a double groove on the lateral surface in the fastening area, the double groove comprising two individual grooves following one another in the longitudinal direction, which are separated from one another by a sealing lug pointing away from the longitudinal axis in order to enable gas-tight compression of the base body head with the fastening area in the area of the double groove
- connection side and "gas tank side” are to be understood with regard to the intended use. Likewise, one could speak of a first end face (instead of an end face on the connection side) and a second end face (instead of an end face on the gas container side).
- two individual grooves located one behind the other are arranged in the fastening area on the lateral surface of the valve body in such a way that an elevation is formed between them.
- This elevation forms the sealing nose, through which the valve body can be connected in a gas-tight manner by means of two compressions formed one behind the other on the gas container or on its gas container neck or base body head.
- a double pressing of the valve body with the gas container by means of a forming process preferably a rolling (a manufacturing process known per se for forming rotationally symmetrical semi-finished products, whereby in the case of tubular semi-finished products by controlled closing of internal and/or external shape-determining tools and by continuous rolling on the beads or grooves running around the workpiece can be produced), which can reliably prevent the gas container from bursting, in particular in the area of the gas container neck, or the valve body from being pressed out of the gas container neck or the head of the base body at more than 500 bar, preferably up to a maximum pressure of 550 bar.
- a rolling a manufacturing process known per se for forming rotationally symmetrical semi-finished products, whereby in the case of tubular semi-finished products by controlled closing of internal and/or external shape-determining tools and by continuous rolling on the beads or grooves running around the workpiece can be produced
- such an arrangement ensures that the gas tank at a pressure that is at a maximum permissible fill factor of 0.75 kg/l (for carbon dioxide (CO2) or nitrous oxide (N2O)) and a temperature of approx. 130°C, preserves its integrity and shape.
- the limited available installation space is optimally taken into account by the double groove.
- connection area extends in the longitudinal direction from an initial area (comprising the end face on the connection side) to an end area (comprising the stop face).
- the diameter of the connection area, particularly in its end area, is larger than the diameter of the fastening area, which typically applies to the entire fastening area.
- Each individual groove has an individual groove base.
- the sealing lug protrudes beyond these individual groove bases.
- the fastening area is preferably pushed completely or so far into the base body head that the base body head contacts the stop surface acting as a stop.
- the continuous longitudinal bore comprises at least three bore sections with at least two different diameters. This enables the drill sections to be functionalized differently, with larger diameters being advantageous with regard to unhindered gas flow, for example, and a smaller diameter proving to be advantageous for the bearing of the valve tappet.
- At least one first drilling section is arranged in the connection area and that at least a second and third drilling section are arranged in the fastening area.
- This arrangement not only proves to be particularly favorable in terms of production technology, but can also be advantageous with regard to the different functionality of the individual drilling sections.
- the bore section provided for mounting the valve tappet is arranged in the fastening area, a mechanically extremely stable mounting is ensured when the fastening area is pushed into the base body head of the gas container and pressed gas-tight with it.
- more than one first drilling section is arranged in the connection area and/or that more than two drilling sections (or more than the second drilling section and the third drilling section, e.g. a fourth or a fourth and a fifth drilling section) are provided in the fastening area could be.
- the second drilling section located between the first drilling section and the third drilling section has a smaller diameter than the first drilling section and the third drilling section, with the valve tappet being slidably mounted in the second drilling section is.
- the valve body has a first snap-in lug arrangement in the longitudinal bore in the fastening area, preferably in a third bore section of the longitudinal bore, through which first snap-in lug arrangement a section-wise narrowing of the longitudinal bore in the fastening area, preferably in the third Drilling section, is ensured, wherein the first snap-in nose arrangement has at least one bulge pointing towards the longitudinal axis.
- This first snap-in lug arrangement serves to ensure a secure, pressure-based movement and retention of the valve tappet in the valve body while the gas container is being filled with gas.
- valve tappet can be moved from a closed position, in which the valve or the longitudinal bore is closed in a gas-tight manner by the valve tappet, along the longitudinal axis in the longitudinal direction into a filling position.
- the valve tappet releases the valve or the longitudinal bore for gas, so that gas can flow through the valve or the longitudinal bore, the valve tappet being in contact with the first snap-in nose arrangement.
- the first snap-in lug arrangement prevents further movement of the valve tappet in the longitudinal direction by means of a positive fit.
- valve tappet can be pushed at least in sections over the first snap-in nose arrangement or over its at least one bulge, with the at least one bulge receding elastically away from the longitudinal axis. This elasticity can be ensured by the choice of material for the valve body.
- the first snap-in lug arrangement comprises three bulges, which are arranged at least in sections in a plane normal to the longitudinal axis. This narrowing in sections, caused by the three bulges, causes a particularly reliable positive position fixing of the valve tappet.
- the three bulges of the first snap-in nose arrangement are arranged, preferably symmetrically, at an angular distance of 120° from one another, the angular distance being measured around the longitudinal axis. This guarantees an unhindered flow of gas in a particularly reliable manner, so that the gas can flow between the valve tappet, the bulges and an inner wall of the longitudinal bore when the gas container is being filled and when the gas container is being emptied.
- the valve body has a second snap lug arrangement in the longitudinal bore in the fastening area, preferably in the third bore section, between the first snap lug arrangement and the end surface on the gas container side, through which second snap lug arrangement a further narrowing of the longitudinal bore in the fastening area is achieved in sections , preferably in the third drilling section, is ensured, with the second snap-in lug arrangement having at least one bulge pointing towards the longitudinal axis.
- This second snap-in lug arrangement is used for secure pressure-based movement and retention of the valve tappet in the valve body while the gas tank is being emptied, with the gas flowing out of the gas tank into a device, preferably into a siphon.
- valve tappet in this emptying position, the valve tappet is partially pushed over the first snap-in lug arrangement in the longitudinal direction, so that a portion of the valve tappet is arranged between the first and the second snap-in lug arrangement.
- Another move in Longitudinally beyond the second snap-in lug arrangement is basically prevented by positive locking.
- valve tappet can be pushed at least in sections over the second snap-in nose arrangement or over its at least one bulge, with the at least one bulge receding elastically away from the longitudinal axis.
- This elasticity can be ensured by the choice of material for the valve body.
- valve tappet when the valve is assembled, the valve tappet can be pushed counter to the longitudinal direction over the second snap-in lug arrangement and over the first snap-in lug arrangement.
- a particularly preferred embodiment of the valve according to the invention provides for the second snap-in lug arrangement to have three bulges, which are arranged at least in sections in a plane normal to the longitudinal axis. This narrowing in sections, caused by the three bulges, causes a reliable, form-fit positional fixing of the valve tappet.
- the three bulges of the second snap-in lug arrangement are preferably symmetrically spaced at an angular distance of 120° are arranged to each other, the angular distance being measured around the longitudinal axis. This guarantees an unhindered flow of gas in a particularly reliable manner, so that the gas can flow between the valve tappet, the bulges of the second snap-in lug arrangement and an inner wall of the longitudinal bore both when the gas container is emptied and when the gas container is filled.
- the bulges of the first and second snap-in lug arrangements are congruent to one another or rotated by 60° to one another, viewed along the longitudinal axis are arranged.
- the valve tappet has a thickening which is directed towards the end surface on the gas container side and is at least partially conical and which at least in sections, in particular in an end region pointing towards the end surface on the gas container side, has a maximum diameter which is larger than the diameter of the narrowing in sections formed by the first snap-in nose arrangement.
- this in particular defines the filling position, i.e. when the plunger moves out of the closed position in the longitudinal direction until it abuts against the first snap-in nose arrangement.
- Analog is provided in a particularly preferred embodiment of the valve according to the invention that the Maximum diameter of the thickening is greater than the diameter of the further narrowing in sections formed by the second snap-in lug arrangement.
- valve tappet serves on the one hand as a sealing element to the valve body and on the other hand as an opening element.
- the maximum diameter of the valve tappet is smaller than a diameter of an opening cross section of the longitudinal bore in the fastening area or the third bore section. This allows gas to flow past between the thickening and the inner wall of the longitudinal bore or the inner wall of the third bore section.
- valve tappet is made of metal, preferably steel or stainless steel or brass, or ceramic.
- the valve body is made from a high-temperature-resistant plastic, in particular from polyethersulfone (PES) or polysulfone (PSU) or polyetheretherketone (PEEK) or polyphenylene sulfide (PPS) or polyphenylsulfone (PPSU) or polyetherimide (PEI). , is manufactured.
- PES polyethersulfone
- PSU polysulfone
- PEEK polyetheretherketone
- PPS polyphenylene sulfide
- PPSU polyphenylsulfone

Description
Die vorliegende Erfindung betrifft ein Ventil zum Verschließen eines Gasbehälters, das Ventil umfassend einen Ventilkörper mit einer durchgehende Längsbohrung entlang einer Längsachse, in welcher Längsbohrung ein verschiebbar geführter Ventilstößel gelagert ist, wobei sich der Ventilkörper in einer parallel zur Längsachse verlaufenden Längsrichtung von einem Anschlussbereich mit einer anschlussseitigen Endfläche zu einem Befestigungsbereich mit einer gasbehälterseitigen Endfläche erstreckt, wobei der Befestigungsbereich einen geringeren Durchmesser als der Anschlussbereich aufweist und der Anschlussbereich eine Anschlagfläche aufweist, um einen Anschlag für einen Basiskörperkopf des Gasbehälters bereitzustellen, wenn der Befestigungsbereich durch eine Öffnung des Basiskörperkopfs in diesen eingeschoben ist.The present invention relates to a valve for closing a gas container, the valve comprising a valve body with a continuous longitudinal bore along a longitudinal axis, in which longitudinal bore a displaceably guided valve tappet is mounted, the valve body extending in a longitudinal direction parallel to the longitudinal axis from a connection area with a end surface on the connection side to a fastening area with an end surface on the gas container side, the fastening area having a smaller diameter than the connection area and the connection area having a stop surface in order to provide a stop for a base body head of the gas container when the fastening area is inserted through an opening in the base body head into the latter .
Mit Gas gefüllte Gasbehälter können mit einer Vorrichtung, beispielsweise einem Sodasiphon, einem Schlagsahnesiphon oder einem Druckregler, gasdicht verbunden werden, um eine entsprechende Gasversorgung des Siphons bzw. der Vorrichtung zu gewährleisten.Gas containers filled with gas can be connected in a gas-tight manner to a device, for example a soda siphon, a whipped cream siphon or a pressure regulator, in order to ensure a corresponding gas supply to the siphon or the device.
Dabei ist es bekannt, kohlensäurehaltige Getränke, insbesondere Soda, sowie Schlagsahne mittels eines Siphons, der mit einem entsprechenden Gasbehälter zusammenwirkt, für den Bedarf eines Benutzers herzustellen, wobei das Wasser mit Kohlendioxid (CO2) bzw. die Sahne mit Distickstoffmonoxid (N2O) aus dem Gasbehälter angereichert wird. Weiters gewinnen auch mit Stickstoff (N2) oder Argon (Ar) gefüllte Gasbehälter für verschiedenste Einsatzzwecke, insbesondere mit Siphons bzw. Siphonflaschen, immer mehr an Bedeutung.It is known that carbonated drinks, especially soda, and whipped cream by means of a siphon, cooperating with an appropriate gas tank, for the needs of a user, whereby the water is enriched with carbon dioxide (CO2) or the cream with nitrous oxide (N2O) from the gas tank. Furthermore, gas containers filled with nitrogen (N2) or argon (Ar) are becoming more and more important for a wide variety of applications, in particular with siphons or siphon bottles.
Da hierbei zur Gewährleistung eines optimalen Ergebnisses hohe Drücke erforderlich sind, ist die Gefahr eines unkontrollierten Berstens des Gasbehälters gegeben. In gleicher Weise ist bei Verwendung etwaiger Ventile, welche im Falle handelsüblicher kapselförmiger Gasbehälter jeweils im Bereich eines Gasbehälterhalses angeordnet sind, die Gefahr gegeben, dass das Ventil bzw. dessen Ventilkörper durch die hohen Drücke aus dem Gasbehälter herausgedrückt wird. Ebenso kann bei einer etwaigen Schwächung des Gasbehälterhalses durch die Anordnung des Ventils ein duktiles Bersten, insbesondere bei Temperaturen höher als 130°C, auftreten, wodurch der Benutzer etwaige Verletzungen davontragen kann.Since high pressures are necessary to ensure an optimal result, there is a risk of the gas container bursting in an uncontrolled manner. In the same way, when using any valves which are arranged in the area of a gas container neck in the case of commercially available capsule-shaped gas containers, there is a risk that the valve or its valve body will be pressed out of the gas container by the high pressures. Likewise, if the neck of the gas container is weakened by the arrangement of the valve, a ductile bursting can occur, in particular at temperatures higher than 130° C., as a result of which the user can sustain any injuries.
Dahingehend offenbart die
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Ventil für einen Gasbehälter zu schaffen, welches die genannten Nachteile vermeidet. Insbesondere soll beim erfindungsgemäßen Ventil auch bei einem hohen Druck des Gases im Gasbehälter eine Sicherung vor einem etwaigen Herausdrücken bzw. Herausschieben des Ventils bzw. eines Ventilkörpers des Ventils aus dem Gasbehälter gewährleistet sein, wobei vorzugsweise zusätzlich eine gesicherte druckbasierte Bewegung sowie Halterung eines im Ventilkörper verschiebbar gelagerten Ventilstößels gewährleistet sein soll.It is therefore an object of the present invention to create a valve for a gas container which avoids the disadvantages mentioned. In particular, with the valve according to the invention, even at high pressure of the gas in the gas tank, protection should be ensured against the valve or a valve body of the valve being pushed out or pushed out of the gas tank, with preferably additionally a secured pressure-based movement and mounting of a displaceable valve in the valve body mounted valve tappet should be guaranteed.
Zur Lösung der genannten Aufgabe ist es bei einem Ventil zum Verschließen eines Gasbehälters, das Ventil umfassend einen Ventilkörper mit einer durchgehenden Längsbohrung entlang einer Längsachse, in welcher Längsbohrung ein verschiebbar geführter Ventilstößel gelagert ist, wobei sich der Ventilkörper in einer parallel zur Längsachse verlaufenden Längsrichtung von einem Anschlussbereich mit einer anschlussseitigen Endfläche zu einem Befestigungsbereich mit einer gasbehälterseitigen Endfläche erstreckt, wobei der Befestigungsbereich einen geringeren Durchmesser als der Anschlussbereich aufweist und der Anschlussbereich eine Anschlagfläche aufweist, um einen Anschlag für einen Basiskörperkopf des Gasbehälters bereitzustellen, wenn der Befestigungsbereich durch eine Öffnung des Basiskörperkopfs in diesen eingeschoben ist, erfindungsgemäß vorgesehen, dass der Ventilkörper mantelflächig im Befestigungsbereich eine Doppelnut aufweist, wobei die Doppelnut zwei in Längsrichtung aufeinander folgende Einzelnuten umfasst, die durch eine von der Längsachse weg weisende Dichtnase voneinander getrennt sind, um eine gasdichte Verpressung des Basiskörperkopfs mit dem Befestigungsbereich im Bereich der Doppelnut zu ermöglichen, wenn der Befestigungsbereich mit der Doppelnut in den Basiskörperkopf eingeschoben ist.In order to achieve the stated object, a valve for closing a gas container has a valve comprising a valve body with a continuous longitudinal bore along a longitudinal axis, in which longitudinal bore a displaceably guided valve tappet is mounted, the valve body extending in a longitudinal direction parallel to the longitudinal axis from a connection area with an end face on the connection side to a fastening area with an end face on the gas container side, the fastening area having a smaller diameter than the connection area and the connection area having a stop surface in order to provide a stop for a base body head of the gas container when the fastening area passes through an opening in the base body head is inserted into this, according to the invention that the valve body has a double groove on the lateral surface in the fastening area, the double groove comprising two individual grooves following one another in the longitudinal direction, which are separated from one another by a sealing lug pointing away from the longitudinal axis in order to enable gas-tight compression of the base body head with the fastening area in the area of the double groove when the fastening area with the double groove is pushed into the base body head.
Die Begriffe "anschlussseitig" und "gasbehälterseitig" sind im Hinblick auf die bestimmungsgemäße Verwendung zu verstehen. Ebenso könnte man von einer ersten Endfläche (statt von einer anschlussseitigen Endfläche) und einer zweiten Endfläche (statt von einer gasbehälterseitigen Endfläche) sprechen.The terms "connection side" and "gas tank side" are to be understood with regard to the intended use. Likewise, one could speak of a first end face (instead of an end face on the connection side) and a second end face (instead of an end face on the gas container side).
Mit anderen Worten sind an der Mantelfläche des Ventilkörpers zwei hintereinander liegende Einzelnuten im Befestigungsbereich derart angeordnet, dass dazwischen eine Erhebung ausgebildet ist. Diese Erhebung bildet die Dichtnase, durch welche der Ventilkörper mittels zweier hintereinander ausgebildeter Verpressungen an dem Gasbehälter bzw. an dessen Gasbehälterhals bzw. Basiskörperkopf gasdicht verbindbar ist. Das heißt, dass eine doppelte Verpressung des Ventilkörpers mit dem Gasbehälter mittels eines Umformprozesses, vorzugsweise einer Rollierung (an sich bekanntes Fertigungsverfahren zur Umformung rotationssymmetrischer Halbzeuge, wobei bei Rohrhalbzeugen durch gesteuertes Zufahren von innen- und/oder außenliegenden formbestimmenden Werkzeugen und durch kontinuierliches Abrollen auf dem Werkstück umlaufende Sicken oder Nuten erzeugt werden), erfolgen kann, wodurch ein etwaiges Bersten des Gasbehälters, insbesondere im Bereich des Gasbehälterhalses, oder ein etwaiges Herauspressen des Ventilkörpers aus dem Gasbehälterhals bzw. dem Basiskörperkopf bei mehr als 500 bar zuverlässig vermeidbar ist, vorzugsweise bis zu einem Maximaldruck von 550 bar.In other words, two individual grooves located one behind the other are arranged in the fastening area on the lateral surface of the valve body in such a way that an elevation is formed between them. This elevation forms the sealing nose, through which the valve body can be connected in a gas-tight manner by means of two compressions formed one behind the other on the gas container or on its gas container neck or base body head. This means that a double pressing of the valve body with the gas container by means of a forming process, preferably a rolling (a manufacturing process known per se for forming rotationally symmetrical semi-finished products, whereby in the case of tubular semi-finished products by controlled closing of internal and/or external shape-determining tools and by continuous rolling on the beads or grooves running around the workpiece can be produced), which can reliably prevent the gas container from bursting, in particular in the area of the gas container neck, or the valve body from being pressed out of the gas container neck or the head of the base body at more than 500 bar, preferably up to a maximum pressure of 550 bar.
Im Detail ist durch eine derartige Anordnung gewährleistet, dass der Gasbehälter bei einem Druck, der bei einem maximal zulässigen Füllfaktor von 0,75 kg/l (bei Kohlendioxid (CO2) bzw. Distickstoffmonoxid (N2O)) und einer Temperatur von ca. 130°C entsteht, seine Integrität bzw. Form bewahrt. Gleichzeitig wird durch die Doppelnut dem begrenzt verfügbaren Einbauraum optimal Rechnung getragen.In detail, such an arrangement ensures that the gas tank at a pressure that is at a maximum permissible fill factor of 0.75 kg/l (for carbon dioxide (CO2) or nitrous oxide (N2O)) and a temperature of approx. 130°C, preserves its integrity and shape. At the same time, the limited available installation space is optimally taken into account by the double groove.
Zum Anschlussbereich sei bemerkt, dass dieser sich in Längsrichtung von einem Anfangsbereich (umfassend die anschlussseitige Endfläche) bis zu einem Endbereich (umfassend die Anschlagfläche) erstreckt. Der Durchmesser des Anschlussbereichs ist insbesondere in dessen Endbereich größer als der Durchmesser des Befestigungsbereichs, was typischerweise für den gesamten Befestigungsbereich gilt.With regard to the connection area, it should be noted that this extends in the longitudinal direction from an initial area (comprising the end face on the connection side) to an end area (comprising the stop face). The diameter of the connection area, particularly in its end area, is larger than the diameter of the fastening area, which typically applies to the entire fastening area.
Jede Einzelnut weist einen Einzelnutgrund auf. Die Dichtnase ragt über diese Einzelnutgründe hinaus.Each individual groove has an individual groove base. The sealing lug protrudes beyond these individual groove bases.
Wie gesagt, wird eine zuverlässige Verpressung zwischen Basiskörperkopf und Befestigungsbereich im Bereich der Doppelnut ermöglicht, wenn der Befestigungsbereich samt Doppelnut in den Basiskörperkopf eingeschoben ist. Vorzugsweise ist dabei der Befestigungsbereich vollständig bzw. soweit in den Basiskörperkopf eingeschoben, dass der Basiskörperkopf die als Anschlag wirkende Anschlagfläche kontaktiert.As stated, a reliable pressing between the head of the base body and the fastening area in the area of the double groove is made possible when the fastening area together with the double groove is pushed into the head of the base body. In this case, the fastening area is preferably pushed completely or so far into the base body head that the base body head contacts the stop surface acting as a stop.
In einer bevorzugten Ausführungsform umfasst die durchgehende Längsbohrung zumindest drei Bohrabschnitte mit zumindest zwei unterschiedlichen Durchmessern. Dies ermöglicht eine unterschiedliche Funktionalisierung der Bohrabschnitte, wobei größere Durchmesser z.B. vorteilhaft im Hinblick auf einen ungehinderten Gasfluss sind und ein kleinerer Durchmesser sich als vorteilhaft für die Lagerung des Ventilstößels erweist.In a preferred embodiment, the continuous longitudinal bore comprises at least three bore sections with at least two different diameters. This enables the drill sections to be functionalized differently, with larger diameters being advantageous with regard to unhindered gas flow, for example, and a smaller diameter proving to be advantageous for the bearing of the valve tappet.
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils ist vorgesehen, dass zumindest ein erster Bohrabschnitt im Anschlussbereich angeordnet ist und dass zumindest ein zweiter und dritter Bohrabschnitt im Befestigungsbereich angeordnet sind. Diese Anordnung erweist sich nicht nur als herstellungstechnisch besonders günstig, sondern kann auch vorteilhaft im Hinblick auf die unterschiedliche Funktionalität der einzelnen Bohrabschnitte sein. Insbesondere wenn z.B. der für die Lagerung des Ventilstößels vorgesehene Bohrabschnitte im Befestigungsbereich angeordnet ist, wird eine mechanisch extrem stabile Lagerung gewährleistet, wenn der Befestigungsbereich in den Basiskörperkopf des Gasbehälters eingeschoben und mit diesem gasdicht verpresst ist.In a particularly preferred embodiment of the valve according to the invention it is provided that at least one first drilling section is arranged in the connection area and that at least a second and third drilling section are arranged in the fastening area. This arrangement not only proves to be particularly favorable in terms of production technology, but can also be advantageous with regard to the different functionality of the individual drilling sections. Particularly if, for example, the bore section provided for mounting the valve tappet is arranged in the fastening area, a mechanically extremely stable mounting is ensured when the fastening area is pushed into the base body head of the gas container and pressed gas-tight with it.
Selbstverständlich ist auch denkbar, dass mehr als ein erster Bohrabschnitt im Anschlussbereich angeordnet sind und/oder dass mehr als zwei Bohrabschnitte (bzw. mehr als der zweite Bohrabschnitt und der dritte Bohrabschnitt, z.B. ein vierter oder ein vierter und ein fünfter Bohrabschnitt) im Befestigungsbereich vorgesehen sein können.Of course, it is also conceivable that more than one first drilling section is arranged in the connection area and/or that more than two drilling sections (or more than the second drilling section and the third drilling section, e.g. a fourth or a fourth and a fifth drilling section) are provided in the fastening area could be.
Gemäß dem oben Gesagten ist es bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils vorgesehen, dass der zwischen dem ersten Bohrabschnitt und dem dritten Bohrabschnitt liegende zweite Bohrabschnitt einen kleineren Durchmesser als der erste Bohrabschnitt und der dritte Bohrabschnitt aufweist, wobei im zweiten Bohrabschnitt der Ventilstößel verschiebbar gelagert ist.In accordance with the above, it is provided in a particularly preferred embodiment of the valve according to the invention that the second drilling section located between the first drilling section and the third drilling section has a smaller diameter than the first drilling section and the third drilling section, with the valve tappet being slidably mounted in the second drilling section is.
Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Ventils ist vorgesehen, dass der Ventilkörper in der Längsbohrung im Befestigungsbereich, vorzugsweise in einem dritten Bohrabschnitt der Längsbohrung, eine erste Schnappnasenanordnung aufweist, durch welche erste Schnappnasenanordnung eine abschnittsweise Verengung der Längsbohrung im Befestigungsbereich, vorzugsweise im dritten Bohrabschnitt, gewährleistet ist, wobei die erste Schnappnasenanordnung mindestens eine zur Längsachse weisende Ausbuchtung aufweist. Diese erste Schnappnasenanordnung dient zur Gewährleistung einer gesicherten druckbasierten Bewegung sowie Halterung des Ventilstößels im Ventilkörper während eines Befüllens des Gasbehälters mit Gas. Konkret kann der Ventilstößel aus einer Schließposition, bei der das Ventil bzw. die Längsbohrung durch den Ventilstößel gasdicht verschlossen ist, entlang der Längsachse in Längsrichtung bis in eine Füllposition bewegt werden. In der Füllposition gibt der Ventilstößel das Ventil bzw. die Längsbohrung für Gas frei, sodass Gas durch das Ventil bzw. die Längsbohrung strömen kann, wobei der Ventilstößel an der ersten Schnappnasenanordnung ansteht. D.h. die erste Schnappnasenanordnung unterbindet durch Formschluss eine weitere Bewegung des Ventilstößels in Längsrichtung.In a preferred embodiment of the valve according to the invention, it is provided that the valve body has a first snap-in lug arrangement in the longitudinal bore in the fastening area, preferably in a third bore section of the longitudinal bore, through which first snap-in lug arrangement a section-wise narrowing of the longitudinal bore in the fastening area, preferably in the third Drilling section, is ensured, wherein the first snap-in nose arrangement has at least one bulge pointing towards the longitudinal axis. This first snap-in lug arrangement serves to ensure a secure, pressure-based movement and retention of the valve tappet in the valve body while the gas container is being filled with gas. In concrete terms, the valve tappet can be moved from a closed position, in which the valve or the longitudinal bore is closed in a gas-tight manner by the valve tappet, along the longitudinal axis in the longitudinal direction into a filling position. In the filling position, the valve tappet releases the valve or the longitudinal bore for gas, so that gas can flow through the valve or the longitudinal bore, the valve tappet being in contact with the first snap-in nose arrangement. This means that the first snap-in lug arrangement prevents further movement of the valve tappet in the longitudinal direction by means of a positive fit.
Allerdings kann der Ventilstößel durch Aufbringung einer hinreichend großen Kraft in Längsrichtung - oder prinzipiell auch gegen die Längsrichtung - zumindest abschnittsweise über die erste Schnappnasenanordnung bzw. über deren mindestens eine Ausbuchtung geschoben werden, wobei die mindestens eine Ausbuchtung elastisch von der Längsachse weg weisend zurückweicht. Diese Elastizität kann durch die Materialwahl des Ventilkörpers gewährleistet sein.However, by applying a sufficiently large force in the longitudinal direction - or in principle also against the longitudinal direction - the valve tappet can be pushed at least in sections over the first snap-in nose arrangement or over its at least one bulge, with the at least one bulge receding elastically away from the longitudinal axis. This elasticity can be ensured by the choice of material for the valve body.
Um sowohl eine möglichst hohe Sicherung der Bewegungsfreiheit als auch Halterung des Ventilstößels zu gewährleisten, ist es bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils vorgesehen, dass die erste Schnappnasenanordnung drei Ausbuchtungen umfasst, die zumindest abschnittsweise in einer Ebene normal zur Längsachse angeordnet sind. Diese durch die drei Ausbuchtungen verursachte abschnittsweise Verengung bewirkt eine besonders zuverlässige formschlüssige Lagefixierung des Ventilstößels.In order to ensure both the greatest possible freedom of movement and retention of the valve tappet, it is provided in a particularly preferred embodiment of the valve according to the invention that the first snap-in lug arrangement comprises three bulges, which are arranged at least in sections in a plane normal to the longitudinal axis. This narrowing in sections, caused by the three bulges, causes a particularly reliable positive position fixing of the valve tappet.
Ein Winkelabstand der Ausbuchtungen zueinander ermöglicht einen ungehinderten Gasfluss, wenn der Ventilstößel in der Füllposition ist und an der ersten Schnappnasenanordnung ansteht. Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils ist vorgesehen, dass die drei Ausbuchtungen der ersten Schnappnasenanordnung, vorzugsweise symmetrisch, mit einem Winkelabstand von jeweils 120° zueinander angeordnet sind, wobei der Winkelabstand rund um die Längsachse gemessen ist. Dies garantiert besonders zuverlässig einen ungehinderten Gasfluss, sodass das Gas beim Befüllen des Gasbehälters als auch beim Entleeren des Gasbehälters zwischen dem Ventilstößel, den Ausbuchtungen und einer Innenwand der Längsbohrung strömen kann.Angular spacing of the bulges from one another allows for unhindered gas flow when the valve stem is in the fill position and abuts the first snap lug assembly. In a particularly preferred embodiment of the valve according to the invention, it is provided that the three bulges of the first snap-in nose arrangement are arranged, preferably symmetrically, at an angular distance of 120° from one another, the angular distance being measured around the longitudinal axis. This guarantees an unhindered flow of gas in a particularly reliable manner, so that the gas can flow between the valve tappet, the bulges and an inner wall of the longitudinal bore when the gas container is being filled and when the gas container is being emptied.
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils ist vorgesehen, dass der Ventilkörper in der Längsbohrung im Befestigungsbereich, vorzugsweise im dritten Bohrabschnitt, zwischen der ersten Schnappnasenanordnung und der gasbehälterseitigen Endfläche eine zweite Schnappnasenanordnung aufweist, durch welche zweite Schnappnasenanordnung eine weitere abschnittsweise Verengung der Längsbohrung im Befestigungsbereich, vorzugsweise im dritten Bohrabschnitt, gewährleistet ist, wobei die zweite Schnappnasenanordnung mindestens eine zur Längsachse weisende Ausbuchtung aufweist. Diese zweite Schnappnasenanordnung dient zur sicheren druckbasierten Bewegung sowie Halterung des Ventilstößels im Ventilkörper während eines Entleerens des Gasbehälters, wobei das Gas aus dem Gasbehälter in eine Vorrichtung, vorzugsweise in einen Siphon, strömt. D.h. in dieser Entleerungsposition ist der Ventilstößel in Längsrichtung abschnittsweise über die erste Schnappnasenanordnung geschoben, sodass ein Abschnitt des Ventilstößels zwischen der ersten und der zweiten Schnappnasenanordnung angeordnet ist. Eine weitere Bewegung in Längsrichtung über die zweite Schnappnasenanordnung hinaus wird grundsätzlich durch Formschluss unterbunden.In a particularly preferred embodiment of the valve according to the invention, it is provided that the valve body has a second snap lug arrangement in the longitudinal bore in the fastening area, preferably in the third bore section, between the first snap lug arrangement and the end surface on the gas container side, through which second snap lug arrangement a further narrowing of the longitudinal bore in the fastening area is achieved in sections , preferably in the third drilling section, is ensured, with the second snap-in lug arrangement having at least one bulge pointing towards the longitudinal axis. This second snap-in lug arrangement is used for secure pressure-based movement and retention of the valve tappet in the valve body while the gas tank is being emptied, with the gas flowing out of the gas tank into a device, preferably into a siphon. In other words, in this emptying position, the valve tappet is partially pushed over the first snap-in lug arrangement in the longitudinal direction, so that a portion of the valve tappet is arranged between the first and the second snap-in lug arrangement. Another move in Longitudinally beyond the second snap-in lug arrangement is basically prevented by positive locking.
Allerdings kann der Ventilstößel durch Aufbringung einer hinreichend großen Kraft in Längsrichtung - oder prinzipiell auch gegen die Längsrichtung - zumindest abschnittsweise über die zweite Schnappnasenanordnung bzw. über deren mindestens eine Ausbuchtung geschoben werden, wobei die mindestens eine Ausbuchtung elastisch von der Längsachse weg weisend zurückweicht. Diese Elastizität kann durch die Materialwahl des Ventilkörpers gewährleistet sein.However, by applying a sufficiently large force in the longitudinal direction - or in principle also against the longitudinal direction - the valve tappet can be pushed at least in sections over the second snap-in nose arrangement or over its at least one bulge, with the at least one bulge receding elastically away from the longitudinal axis. This elasticity can be ensured by the choice of material for the valve body.
Entsprechend kann der Ventilstößel beim Zusammenbau des Ventils gegen die Längsrichtung über die zweite Schnappnasenanordnung sowie über die erste Schnappnasenanordnung geschoben werden.Correspondingly, when the valve is assembled, the valve tappet can be pushed counter to the longitudinal direction over the second snap-in lug arrangement and over the first snap-in lug arrangement.
Um hierbei ebenso eine möglichst hohe Sicherung der Bewegungsfreiheit als auch Halterung des Ventilstößels zu gewährleisten, ist es bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils vorgesehen, dass die zweite Schnappnasenanordnung drei Ausbuchtungen umfasst, die zumindest abschnittsweise in einer Ebene normal zur Längsachse angeordnet sind. Diese durch die drei Ausbuchtungen verursachte abschnittsweise Verengung bewirkt eine zuverlässige formschlüssige Lagefixierung des Ventilstößels.In order to ensure the greatest possible freedom of movement and retention of the valve tappet, a particularly preferred embodiment of the valve according to the invention provides for the second snap-in lug arrangement to have three bulges, which are arranged at least in sections in a plane normal to the longitudinal axis. This narrowing in sections, caused by the three bulges, causes a reliable, form-fit positional fixing of the valve tappet.
Ein Winkelabstand der Ausbuchtungen der zweiten Schnappnasenanordnung zueinander ermöglicht einen ungehinderten Gasfluss, wenn der Ventilstößel in der Entleerungsposition ist und an der zweiten Schnappnasenanordnung ansteht. Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils ist vorgesehen, dass die drei Ausbuchtungen der zweiten Schnappnasenanordnung, vorzugsweise symmetrisch, mit einem Winkelabstand von 120° zueinander angeordnet sind, wobei der Winkelabstand rund um die Längsachse gemessen ist. Dies garantiert besonders zuverlässig einen ungehinderten Gasfluss, sodass das Gas sowohl beim Entleeren des Gasbehälters als auch beim Befüllen des Gasbehälters zwischen dem Ventilstößel, den Ausbuchtungen der zweiten Schnappnasenanordnung und einer Innenwand der Längsbohrung strömen kann.Angular spacing of the lobes of the second snap lug assembly from one another allows for unimpeded flow of gas when the valve stem is in the deflation position and abuts the second snap lug assembly. In a particularly preferred embodiment of the valve according to the invention, it is provided that the three bulges of the second snap-in lug arrangement are preferably symmetrically spaced at an angular distance of 120° are arranged to each other, the angular distance being measured around the longitudinal axis. This guarantees an unhindered flow of gas in a particularly reliable manner, so that the gas can flow between the valve tappet, the bulges of the second snap-in lug arrangement and an inner wall of the longitudinal bore both when the gas container is emptied and when the gas container is filled.
Um einen optimalen, möglichst ungehinderten Gasfluss sicherzustellen, wenn sich der Ventilstößel in der Entleerungsposition befindet, ist es bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils vorgesehen, dass die Ausbuchtungen der ersten und zweiten Schnappnasenanordnungen entlang der Längsachse gesehen deckungsgleich zueinander oder um 60° verdreht zueinander angeordnet sind.In order to ensure an optimal gas flow that is as unhindered as possible when the valve tappet is in the emptying position, it is provided in a particularly preferred embodiment of the valve according to the invention that the bulges of the first and second snap-in lug arrangements are congruent to one another or rotated by 60° to one another, viewed along the longitudinal axis are arranged.
Um ein etwaiges Herausgleiten des Ventilstößels aus dem Ventilkörper, insbesondere während des Befüllens des Gasbehälters, zu vermeiden, ist es bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils vorgesehen, dass der Ventilstößel eine zur gasbehälterseitigen Endfläche gerichtete, zumindest abschnittsweise konusförmig verlaufende Verdickung aufweist, welche zumindest abschnittsweise, insbesondere in einem zur gasbehälterseitigen Endfläche weisenden Endbereich, einen Maximaldurchmesser aufweist, der größer ist als der Durchmesser der durch die erste Schnappnasenanordnung ausgebildeten abschnittsweisen Verengung. Hierdurch wird, wie oben bereits erläutert, insbesondere die Füllposition definiert, d.h. wenn sich der Stößel aus der Schließposition in Längsrichtung bewegt, bis er an der ersten Schnappnasenanordnung ansteht.In order to prevent the valve tappet from sliding out of the valve body, in particular during the filling of the gas container, it is provided in a particularly preferred embodiment of the valve according to the invention that the valve tappet has a thickening which is directed towards the end surface on the gas container side and is at least partially conical and which at least in sections, in particular in an end region pointing towards the end surface on the gas container side, has a maximum diameter which is larger than the diameter of the narrowing in sections formed by the first snap-in nose arrangement. As already explained above, this in particular defines the filling position, i.e. when the plunger moves out of the closed position in the longitudinal direction until it abuts against the first snap-in nose arrangement.
Analog ist bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils vorgesehen, dass der Maximaldurchmesser der Verdickung größer ist als der Durchmesser der durch die zweite Schnappnasenanordnung ausgebildeten weiteren abschnittsweisen Verengung. Hierdurch wird, wie oben bereits erläutert, insbesondere die Entleerungsposition definiert, d.h. wenn sich der Ventilstößel aus der Füllposition in Längsrichtung weiter bewegt, (zumindest mit einem den Maximaldurchmesser aufweisenden Abschnitt) über die erste Schnappnasenanordnung, bis er an der zweiten Schnappnasenanordnung ansteht.Analog is provided in a particularly preferred embodiment of the valve according to the invention that the Maximum diameter of the thickening is greater than the diameter of the further narrowing in sections formed by the second snap-in lug arrangement. As already explained above, this particularly defines the emptying position, ie when the valve tappet moves further from the filling position in the longitudinal direction (at least with a section having the maximum diameter) over the first snap-in lug arrangement until it abuts the second snap-in lug arrangement.
Eine gesicherte druckbasierte Bewegung sowie Halterung des im Ventilkörper verschiebbar gelagerten Ventilstößels ist somit gewährleistet. Entsprechend dient der Ventilstößel einerseits als Dichtelement zum Ventilkörper und andererseits als Öffnungselement.A secure, pressure-based movement and retention of the valve tappet, which is movably mounted in the valve body, is thus guaranteed. Accordingly, the valve tappet serves on the one hand as a sealing element to the valve body and on the other hand as an opening element.
Hierbei gilt es zu beachten, dass der Maximaldurchmesser des Ventilstößels kleiner ist als ein Durchmesser eines Öffnungsquerschnitts der Längsbohrung im Befestigungsbereich bzw. des dritten Bohrabschnitts. Dies ermöglicht ein Vorbeiströmen von Gas zwischen der Verdickung und der Innenwand der Längsbohrung bzw. der Innenwand des dritten Bohrabschnitts.It should be noted here that the maximum diameter of the valve tappet is smaller than a diameter of an opening cross section of the longitudinal bore in the fastening area or the third bore section. This allows gas to flow past between the thickening and the inner wall of the longitudinal bore or the inner wall of the third bore section.
Dabei ist in einer bevorzugten Ausführungsform der Ventilstößel aus Metall, vorzugsweise Stahl oder Edelstahl oder Messing, oder aus Keramik ausgebildet.In a preferred embodiment, the valve tappet is made of metal, preferably steel or stainless steel or brass, or ceramic.
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Ventils ist vorgesehen, dass der Ventilkörper aus einem hochtemperaturbeständigen Kunststoff, insbesondere aus Polyethersulfon (PES) oder Polysulfon (PSU) oder Polyetheretherketon (PEEK) oder Polyphenylensulfid (PPS) oder Polyphenylsulfon (PPSU) oder Polyetherimide (PEI), gefertigt ist. Im Zusammenspiel mit dem Ventilstößel kann somit eine optimale Dichtheit erzielt werden, wobei außerdem eine Stabilität bei Temperaturen von zumindest ca. 130°C gewährleistet ist.In a particularly preferred embodiment of the valve according to the invention, it is provided that the valve body is made from a high-temperature-resistant plastic, in particular from polyethersulfone (PES) or polysulfone (PSU) or polyetheretherketone (PEEK) or polyphenylene sulfide (PPS) or polyphenylsulfone (PPSU) or polyetherimide (PEI). , is manufactured. In interaction with the valve tappet, optimal tightness can thus be achieved stability at temperatures of at least approx. 130°C is guaranteed.
Weiters ist eine hinreichende Elastizität des Materials gegeben, um die erste und zweite Schnappnasenanordnung mit elastischen Ausbuchtungen, die einstückig mit dem Ventilkörper sind, zu verwirklichen.Furthermore, there is sufficient elasticity of the material in order to realize the first and second snap-in nose arrangement with elastic bulges which are in one piece with the valve body.
Analog zum oben Gesagten ist erfindungsgemäß ein Gasbehälter mit einem erfindungsgemäßen Ventil vorgesehen, der Gasbehälter umfassend einen Basiskörper mit einem eine Öffnung aufweisenden Basiskörperkopf, wobei der Basiskörper zumindest abschnittsweise ein inneres Volumen zur Aufnahme von Gas ausbildet, wobei der Befestigungsbereich mit der Doppelnut durch die Öffnung in den Basiskörperkopf eingeschoben bzw. eingepresst ist, vorzugsweise bis zur Kontaktierung der Anschlagfläche durch den Basiskörperkopf, und wobei der Basiskörperkopf mit dem Befestigungsbereich im Bereich der Doppelnut gasdicht verpresst ist. Hierbei dient der Anschlussbereich des Ventilkörpers zum Anschließen des mit Gas gefüllten Gasbehälters an eine Vorrichtung, vorzugsweise an einen Sahne- oder Sodasiphon.Analogously to what has been said above, a gas container with a valve according to the invention is provided according to the invention, the gas container comprising a base body with a base body head having an opening, the base body forming an inner volume for receiving gas at least in sections, the fastening area with the double groove passing through the opening in is pushed or pressed into the head of the base body, preferably up to the point where the head of the base body makes contact with the stop surface, and wherein the head of the base body is pressed gas-tight with the fastening area in the area of the double groove. The connection area of the valve body serves to connect the gas container filled with gas to a device, preferably to a cream or soda siphon.
Somit ist ein Gasbehälter geschaffen, der gemäß ÖNORM EN 16509, welche kleine ortsbewegliche Flaschen betrifft, nicht wiederbefüllbar ausgebildet ist, wobei es sich um eine sogenannte Einweggaskapsel handelt. Wirtschaftliche Nachteile durch hohe Kosten von wiederbefüllbaren Kapseln, die in wesentlich höheren normativen Anforderungen, wie z.B. Einzelkennzeichnung, wiederkehrende Einzelprüfung oder die Sicherstellung der Lebensmittelreinheit beim Wiederbefüllen etc., begründet sind, werden somit zuverlässig vermieden.A gas container is thus created which, according to ÖNORM EN 16509, which relates to small portable cylinders, is not designed to be refillable, this being what is known as a one-way gas capsule. Economic disadvantages due to the high costs of refillable capsules, which are based on significantly higher normative requirements, such as individual labeling, recurring individual testing or ensuring food purity when refilling, etc., are thus reliably avoided.

Hierbei ist erfindungsgemäß vorgesehen, dass der Ventilkörper 1 mantelflächig im Befestigungsbereich 19 eine Doppelnut 4 aufweist, wobei die Doppelnut 4 zwei in Längsrichtung 40 aufeinander folgende Einzelnuten 41 umfasst, die durch eine von der Längsachse 2 weg weisende Dichtnase 5 voneinander getrennt sind, um eine gasdichte Verpressung des Basiskörperkopfs 27 mit dem Befestigungsbereich 19 im Bereich der Doppelnut 4 zu ermöglichen, wenn der Befestigungsbereich 19 mit der Doppelnut 4 in den Basiskörperkopf 27 eingeschoben ist. Mit anderen Worten sind an der Mantelfläche des Ventilkörpers 1 zwei hintereinander liegende Einzelnuten 41 im Befestigungsbereich 19 derart angeordnet, dass dazwischen eine Dichtnase 5 in Form einer Erhebung ausgebildet ist, wodurch ein etwaiges Herauspressen des Ventilkörpers 1 aus dem Gasbehälter 24 auch bei einem erhöhten Druck vermeidbar ist.The invention provides that the

Die drei Ausbuchtungen 6' der ersten Schnappnasenanordnung 6 sind zumindest abschnittsweise in einer Ebene normal zur Längsachse 2 angeordnet. Um hierbei eine möglichst gleichmäßige Verengung zu gewährleisten, sind die drei Ausbuchtungen 6' innerhalb des dritten Bohrabschnitts 10 symmetrisch mit einem Winkelabstand von jeweils 120° zueinander angeordnet, wobei der Winkelabstand rund um die Längsachse 2 gemessen ist, vgl. insbesondere

Bei Erreichen eines vordefinierten Fülldrucks wird der Ventilstößel 17 in

valve tappet 17 arranged in thevalve body 1 of thegas container 24 with the thickening 42 having themaximum diameter 43 on the base body head side above or in front of the first snap-inlug arrangement 6 as seen in thelongitudinal direction 40, thevalve tappet 17 with the bulges 6' of the first snap-inlug arrangement 6 on the connection side is in contact in such a way that a gap between the sealingedge 16 and the conical thickening 42 of thevalve tappet 17 is guaranteed. Thevalve tappet 17 is thus in the filling position A, cf.6 . - 2. Inflow of the

Im Detail sind zur Entleerung des Gasbehälters 24 nachfolgende Schritte erforderlich:
- 1. Anordnen des Einlassventils 31
über dem Anschlussbereich 18 desVentilkörpers 1 des Ventils 39 desGasbehälters 24, sodass der Anschlussbereich 18 desVentilkörpers 1 indie Gasbehälteraufnahme 35 desEinlassventils 31 ragt; - 2. Schieben des Einlassventils 31
über den Anschlussbereich 18, bis die anschlussseitige Endfläche 20 des Anschlussbereichs 18 andie Anschlagfläche 37der Gasbehälteraufnahme 36 stößt, wobei der Ventilstößel 17durch den Stift 32 des Einlassventils 31 inRichtung des Basiskörpers 26 desGasbehälters 24 über die ersteSchnappnasenanordnung 6 geschoben wird. Die Ausbuchtungen 6' der ersten Schnappnasenanordnung 6 weichen dabei elastisch radial nach außen, d.h.von der Längsachse 2 weg, zurück, wenn der Ventilstößel 17 sich inLängsrichtung 40 bewegt und mitder den Maximaldurchmesser 43aufweisenden Verdickung 42 die Ausbuchtungen 6' passiert.Der den Maximaldurchmesser 43 aufweisende Endbereich der konusförmigen Verdickung 42 desVentilstößels 17 wird somit zwischen der ersten Schnappnasenanordnung 6 und der zweiten Schnappnasenanordnung 7 in der Entleerungsposition C positioniert, sodass sich der Ventilstößel 17 in der Entleerungsposition C befindet. Ein relativ großer Spalt zwischen der Dichtkante 16 desVentilkörpers 1 und der konusförmigen Verdickung 42 desVentilstößels 17 ist hierbei gegeben, vgl.Fig. 10 . - 3.

inlet valve 31 over theconnection area 18 until theend surface 20 of theconnection area 18 on the connection side abuts thestop surface 37 of thegas tank receptacle 36, with thevalve tappet 17 passing through thepin 32 of theinlet valve 31 in the direction of thebase body 26 of thegas tank 24 via the first Snap-nose assembly 6 is pushed. The bulges 6' of the first snap-inlug arrangement 6 yield elastically radially outwards, ie away from thelongitudinal axis 2, when thevalve tappet 17 moves in thelongitudinal direction 40 and the thickenedportion 42 having themaximum diameter 43 passes the bulges 6'. The end region of the conical thickening 42 of thevalve tappet 17 having themaximum diameter 43 is thus positioned in the emptying position C between the first snap-inlug arrangement 6 and the second snap-inlug arrangement 7 , so that thevalve tappet 17 is in the emptying position C.
