Description

Die vorliegende Erfindung betrifft ein Ventil für einen Druckgasbehälter. Bei einem Druckgasbehälter handelt es sich um einen Behälter, dessen Inhalt unter Druck steht und durch Betätigung des Ventils ausgetragen wird. Grundsätzlich kann, wenn es um die Erzeugung von Aerosolen handelt, der Druckgasbehälter auch als Aerosolbehälter angesehen werden. Bei der Verwendung des Druckgasbehälters für gasförmige Arbeitsmedien, bei denen es nicht auf das Gemisch des Arbeitsmediums mit Luft ankommt, spricht man gelegentlich auch von einer Druckgaspackung.The present invention relates to a valve for a compressed gas container. A compressed gas tank is a container whose contents are under pressure and is discharged by actuation of the valve. In principle, when it comes to the production of aerosols, the compressed gas container can also be regarded as an aerosol container. When using the compressed gas container for gaseous working media, in which it does not depend on the mixture of the working medium with air, one speaks occasionally of a pressurized gas package.

Aus WO 2007/104327 A1 ist eine Abgabevorrichtung für ein fließfähiges Medium sowie eine Spendervorrichtung mit einer solchen Abgabevorrichtung bekannt. Die Abgabevorrichtung weist eine Ventilvorrichtung auf, die stromabwärts im Produktabgabekanal angeordnet ist. Die Ventilanordnung ist als ein Überdruckventil ausgebildet, das bei einem gewissen Überdruck im Behälterinneren öffnet und einen ungewollten Austritt des Mediums zulässt. Das Überdruckventil ist als Membranventil ausgebildet, das mit einem Kreuzschlitz versehen ist und sich ab einem vorgegebenen Druckabfall innerhalb des Produktabgabekanals nach außen automatisch zur Abgabe eines Mediums öffnet.Out WO 2007/104327 A1 There is known a dispenser for a flowable medium and a dispenser with such a dispenser. The dispenser includes a valve device located downstream in the product dispensing channel. The valve arrangement is designed as a pressure relief valve which opens at a certain overpressure in the container interior and allows an unwanted escape of the medium. The pressure relief valve is designed as a diaphragm valve, which is provided with a cross slot and opens automatically from a predetermined pressure drop within the product discharge channel to the outside for the delivery of a medium.

Aus EP 0 786 289 B1 ist ein Vordruckpumpenzerstäuber bekannt, der einen sekundären Kolben in dem Ventilglied besitzt, wobei der sekundäre Kolben bei zu großem Druck innerhalb des Behälters aus seiner Dichtposition gedrückt wird, um einen Produktabgabekanal freizugeben.Out EP 0 786 289 B1 For example, there is known a precompressor sprayer having a secondary piston in the valve member, the secondary piston is pressed out of its sealing position at too high pressure within the container to release a product discharge channel.

Aus G 91 11 351.2 ist ein Ventil für Druckgaspackungen bekannt, bei dem das Ventilglied eine Querbohrung besitzt, die durch eine Überdruckeinrichtung verschlossen ist. Für die Überdruckeinrichtung sind eine Reihe von Ansätzen bekannt. So wird vorgeschlagen, die Querbohrung über ein eingeklebtes Dichtelement zu verschließen, das bei zu großem Überdruck die Querbohrung freigibt. Alternativ wird auch vorgeschlagen, einen federvorgespannten Stopfen oder eine dicke Scheibe zum Verschluss der Querbohrung vorzusehen.From G 91 11 351.2 a valve for compressed gas packages is known, in which the valve member has a transverse bore which is closed by a pressure device. For the pressure device, a number of approaches are known. Thus, it is proposed to close the transverse bore via a glued sealing element, which releases the transverse bore at excessively high pressure. Alternatively, it is also proposed to provide a spring-loaded plug or a thick disc for closing the transverse bore.

Der Erfindung liegt die Aufgabe zugrunde, ein Ventil für eine Druckgasbehälter bereitzustellen, das mit möglichst einfachen Mitteln einen Überdruckausgleich des Behälterinnenraums erlaubt und zudem für sehr große Drücke geeignet ist.The invention has for its object to provide a valve for a compressed gas tank, which allows the simplest possible means a pressure equalization of the container interior and also suitable for very high pressures.

Erfindungsgemäß wird die Aufgabe durch ein Ventil mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen bilden den Gegenstand der Unteransprüche.According to the invention the object is achieved by a valve having the features of claim 1. Advantageous embodiments form the subject of the dependent claims.

Das erfindungsgemäße Ventil ist für einen Behälter vorgesehen, dessen Gasfüllung unter Druck steht. Das Ventil besitzt ein längliches Ventilgehäuse, ein Ventilglied sowie ein Dichtelement. Das längliche Ventilgehäuse ist an einem Ende in einem Ventilteller gehalten und umgibt einen Kanal für das auszutragende Medium. Das Ventilglied ist teilweise in dem Kanal des Ventilgehäuses angeordnet und steht aus dem Ventilgehäuse an dessen gehaltenem Ende vor. Über das Ventilglied wird das Ventil betätigt, wobei auf das Ventilglied beispielsweise ein Sprühkopf oder eine andere Betätigungseinrichtung aufgesetzt werden kann. Ferner besitzt das erfindungsgemäße Ventil ein Dichtelement, das das Ventilglied dichtend umschließt und dessen Lage an dem Ventilgehäuse festgelegt ist. Das Ventilglied besitzt einen Austrittskanal, der über mindestens eine Querbohrung in Verbindung mit dem Kanal des Ventilgehäuses bringbar ist. Zum Austragen des Mediums aus dem Druckgasbehälter wird das Ventilglied in eine Position gebracht, so dass es nicht durch das Dichtelement verschlossen ist und der Behälterinnenraum über den Kanal im Ventilgehäuse mit dem Austrittskanal des Ventilgliedes verbunden ist. Bei dem erfindungsgemäßen Ventil ist der Austrittskanal des Ventilgliedes zusätzlich an seinem Grund mit einer Bohrung versehen, über die der Austrittskanal des Ventilgliedes mit dem Kanal des Ventilgehäuses in Verbindung steht. Die Bohrung ist durch einen federvorgespannten Ventilkörper verschlossen, der bei einem vorbestimmten Druck im Kanal des Ventilgehäuses gegen die Federkraft aus der Bohrung bewegt wird und eine direkte Verbindung zwischen Kanal des Ventilgehäuses und Austrittskanal des Ventilgliedes freigibt. Bei der erfindungsgemäßen Lösung ist das Ventilglied mit einer zusätzlichen Bohrung versehen. Dies bedeutet, dass der federvorgespannte Ventilkörper unabhängig von der Betätigung des Ventilgliedes in diesem angeordnet ist. Bei einer regulären Betätigung des Ventilgliedes bleibt der die Bohrung verschließende Ventilkörper in seiner abdichtenden Position. Hierdurch entsteht der Vorteil, dass der Überdruck, bei dem der Ventilkörper von der Bohrung entfernt wird, unabhängig von dem ansonsten bei der Betätigung des Ventils herrschenden Druck gewählt werden kann. Hinzu kommt bei dem erfindungsgemäßen Ventil, dass ein kurzzeitig auftretender Überdruck den Druckgasbehälter nur kurzzeitig öffnet. Sobald der Überdruck nicht ausreicht, den Ventilkörper von der Bohrung zu entfernen, wird das Ventilglied durch den Ventilkörper wieder verschlossen und kann wieder regulär betätigt werden.The valve according to the invention is provided for a container whose gas filling is under pressure. The valve has an elongated valve housing, a valve member and a sealing element. The elongated valve housing is held at one end in a valve plate and surrounds a channel for the medium to be discharged. The valve member is partially disposed in the channel of the valve housing and protrudes from the valve housing at its end held. About the valve member, the valve is actuated, wherein on the valve member, for example, a spray head or other actuator can be placed. Furthermore, the valve according to the invention has a sealing element which surrounds the valve member sealingly and whose position is fixed to the valve housing. The valve member has an outlet channel, which can be brought via at least one transverse bore in connection with the channel of the valve housing. For discharging the medium from the compressed gas container, the valve member is brought into a position so that it is not closed by the sealing element and the container interior is connected via the channel in the valve housing with the outlet channel of the valve member. In the valve according to the invention, the outlet channel of the valve member is additionally provided at its base with a bore through which the outlet channel of the valve member is in communication with the channel of the valve housing. The bore is closed by a spring-biased valve body, which at a predetermined pressure in the channel of the valve housing against the Spring force is moved out of the bore and releases a direct connection between the channel of the valve housing and the outlet channel of the valve member. In the solution according to the invention, the valve member is provided with an additional bore. This means that the spring-biased valve body is arranged independently of the actuation of the valve member in this. In a regular actuation of the valve member of the valve closing the bore body remains in its sealing position. This has the advantage that the overpressure at which the valve body is removed from the bore, regardless of the otherwise prevailing in the operation of the valve pressure can be selected. In addition, in the valve according to the invention that a briefly occurring overpressure opens the compressed gas tank only briefly. Once the pressure is insufficient to remove the valve body from the bore, the valve member is closed by the valve body again and can be operated again regularly.

In einer bevorzugten Ausgestaltung des erfindungsgemäßen Ventils ist als Ventilkörper eine Kugel vorgesehen. Ebenfalls bevorzugt weist die Bohrung im Austrittskanals einen Ventilsitz für den Ventilkörper auf.In a preferred embodiment of the valve according to the invention, a ball is provided as the valve body. Also preferably, the bore in the outlet channel on a valve seat for the valve body.

In einer bevorzugten Ausgestaltung ist das Ventilglied an seinem vom Ventilteller fortweisenden Ende mit einer Kammer im Austrittskanal versehen, in der der Ventilkörper und dessen Feder angeordnet sind. Indem an einem Ende des Ventilgliedes eine Kammer vorgesehen ist, die den Ventilkörper und dessen Feder aufnimmt, kann der regulär verwendete Austrittskanal unabhängig von den Abmessungen der Kammer dimensioniert werden. So wird die Gestaltung des Austrittskanals des Ventilgliedes nicht durch die Abmessungen der Kammer eingeschränkt.In a preferred embodiment, the valve member is at its end facing away from the valve plate with a chamber in the outlet channel provided in which the valve body and its spring are arranged. By having at one end of the valve member a chamber which receives the valve body and its spring, the regularly used discharge channel can be dimensioned independently of the dimensions of the chamber. Thus, the design of the outlet channel of the valve member is not limited by the dimensions of the chamber.

In einer bevorzugten Ausgestaltung ist der Austrittskanal an seinem zum Ventilteller weisenden Ende mit einem Mündungsabschnitt versehen, der durch eine umlaufende Wandung des Ventilgliedes begrenzt ist. Der Mündungsabschnitt kann zylinderförmig oder kegelförmig ausgestaltet sein, wobei der Mündungsabschnitt einen Durchmesser besitzt, der größer als die doppelte Wandstärke des Ventilgliedes ist.In a preferred embodiment, the outlet channel is provided at its end facing the valve head with a mouth portion which is bounded by a circumferential wall of the valve member. The mouth portion may be cylindrical or conical, wherein the mouth portion has a diameter which is greater than twice the wall thickness of the valve member.

In einer bevorzugten Ausgestaltung ist die Kammer im Austrittskanal über mindestens einen Verbindungskanal mit dem Mündungsabschnitt des Austrittskanals verbunden. Durch die Trennung der Strömungswege für das Medium bei regulärem Einsatz und im Fall des Überdrucks können beide Austrittswege für das Medium unabhängig voneinander dimensioniert werden. Durch den mindestens einen Verbindungskanal sind beide Bereiche miteinander verbunden. In einer bevorzugten Ausgestaltung ist der Durchmesser des mindestens einen Verbindungskanals kleiner als der Durchmesser des Mündungsabschnitts.In a preferred embodiment, the chamber is connected in the outlet channel via at least one connecting channel with the mouth portion of the outlet channel. By separating the flow paths for the medium in regular use and in the case of overpressure both exit routes for the medium can be dimensioned independently. Due to the at least one connecting channel both areas are interconnected. In a preferred embodiment, the Diameter of the at least one connecting channel smaller than the diameter of the mouth portion.

Zweckmäßigerweise ist das Ventilglied in seiner federvorgespannten Position derart in dem Ventilgehäuse angeordnet, dass die Querbohrung durch das Dichtelement verschlossen ist oder aus dem Ventilgehäuse vorsteht. In der gegen die Federkraft verschobenen Position des Ventilgliedes ist dieses in dem Ventilgehäuse derart angeordnet, dass die Querbohrung in Verbindung mit dem Kanal des Ventilgehäuses steht. Bei der regulären Betätigung des Ventilgliedes wird dieses axial in das Ventilgehäuse verschoben, wobei der vollständig innerhalb des Ventilgliedes angeordnete Ventilkörper und dessen Feder mitbewegt werden, ohne dass diese sich öffnen.Conveniently, the valve member is arranged in its spring-biased position in the valve housing such that the transverse bore is closed by the sealing element or projects out of the valve housing. In the shifted against the spring force position of the valve member, this is arranged in the valve housing such that the transverse bore is in communication with the channel of the valve housing. In the regular operation of the valve member, this is axially displaced into the valve housing, wherein the valve body completely arranged within the valve body and its spring are moved without them open.

In einer bevorzugten Ausgestaltung ist die an dem Ventilglied angreifende Feder in dem Ventilgehäuse angeordnet und greift an dem vom Ventilteller fortweisenden Ende des Ventilgliedes an.In a preferred embodiment, the force acting on the valve member spring is disposed in the valve housing and engages the end facing away from the valve plate end of the valve member.

Der Kanal in dem Ventilgehäuse besitzt bevorzugt eine Schulter, die die Verschiebung des Ventilgliedes in das Ventilgehäuse begrenzt. Auf diese Weise kann sichergestellt werden, dass das Ventilglied nicht zu weit in das Ventilgehäuse geschoben wird. Ferner ist das Ventilglied mit Vorsprüngen versehen, die in der vorgeschobenen Position des Ventilgliedes an dem Dichtelement anliegen.The channel in the valve housing preferably has a shoulder which limits the displacement of the valve member into the valve housing. In this way it can be ensured that the valve member is not pushed too far into the valve housing. Further, the valve member with projections provided which rest in the advanced position of the valve member to the sealing element.

Das Dichtelement ist bevorzugt als Ring ausgebildet, der einen umlaufenden Ringkörper und eine umlaufende Dichtlippe aufweist, die an dem Ventilglied anliegt. Das Dichtelement sitzt in einer ringförmigen Aussparung des Ventilgehäuses, die durch den Ventilteller begrenzt ist, wobei zweckmäßigerweise das Dichtelement zwischen Ventilteller und Ventilgehäuse eingeklemmt ist.The sealing element is preferably designed as a ring having a circumferential annular body and a circumferential sealing lip, which rests against the valve member. The sealing element is seated in an annular recess of the valve housing, which is delimited by the valve disk, wherein expediently the sealing element is clamped between the valve disk and the valve housing.

Zweckmäßigerweise weist das Ventilglied einen Körper auf, der an seinem vom Ventilteller fortweisenden Ende durch ein Abschlusselement verschlossen ist, wobei das Abschlusselement die durch den federvorgespannten Ventilkörper verschlossene Bohrung aufweist.Conveniently, the valve member has a body which is closed at its end facing away from the valve disc end by a closing element, wherein the closing element has the closed by the spring-biased valve body bore.

Fig. 1 zeigt in einer geschnitten Darstellung das erfindungsgemäße Ventil 10. Das Ventil besitzt einen domförmigen Ventilteller 12, in dem das Ventilgehäuse 14 mit einer Pressverformung gehalten ist. Das Ventilgehäuse 14 besitzt eine längliche Form, die in den Behälter (nicht dargestellt) hineinragt. Das Ventilgehäuse besitzt an seinem vom Ventilteller 12 fortweisenden Ende eine Eintrittsöffnung 16 für das auszutragende Medium. Bei dem auszutragenden Medium kann es sich um Gas oder eine Flüssigkeit handeln. Beispielsweise kann das erfindungsgemäße Ventil eingesetzt werden für einen Druckgasbehälter, in dem flüssiges Kohlendioxid aufbewahrt wird. Das besondere bei flüssigem Kohlendioxid ist, dass dieses bei Raumtemperatur bereits einen Druck von 50 bar annehmen kann, so dass ein Druckausgleich für den Druckbehälter erforderlich ist. Fig. 1 shows in a sectional view of the valve 10 according to the invention. The valve has a dome-shaped valve plate 12, in which the valve housing 14 is held with a compression deformation. The valve housing 14 has an elongate shape which projects into the container (not shown). The valve housing has at its end remote from the valve plate 12 end an inlet opening 16 for the medium to be discharged. The medium to be discharged may be gas or a liquid. For example, the valve according to the invention can be used for a compressed gas container in which liquid carbon dioxide is stored. The special feature of liquid carbon dioxide is that it can already assume a pressure of 50 bar at room temperature, so that a pressure compensation for the pressure vessel is required.

An die Eintrittsöffnung 16 schließt sich ein Kanal 18 an, der sich durch das gesamte Ventilgehäuse erstreckt und stromabwärts des auszutragenden Mediums eine Kammer 20 aufweist. Die Kammer 20 besitzt an ihrem stromaufwärts liegenden Grund einen Absatz 22, auf dem sich eine Feder 24 abstützt.Adjoining the inlet opening 16 is a channel 18, which extends through the entire valve housing and has a chamber 20 downstream of the medium to be discharged. The chamber 20 has at its upstream base a shoulder 22 on which a spring 24 is supported.

In dem Ventilgehäuse 14 ist ein Ventilglied 26 angeordnet, das einen Mündungsabschnitt 28 besitzt. Der Mündungsabschnitt 28 verbreitert sich in dem dargestellten Ausführungsbeispiel kegelförmig hin zu seiner Austrittsöffnung 30. Das Ventilglied besteht aus einem länglichen Körper 66, der den Austrittskanal bildet, und einem Verschlusselement 42. Das Ventilglied 26 besitzt unterhalb des Mündungsabschnitts 28 eine Querbohrung 32, über die das auszutragende Medium in das Ventilglied eintritt. Stromaufwärts von dem Mündungsabschnitt 28 sind in dem dargestellten Ausführungsbeispiel zwei Verbindungskanäle 34 dargestellt, die den Mündungsabschnitt mit einer Kammer 36 verbinden. In der Kammer 36 des Ventilgliedes ist eine Feder 38 und eine als Ventilkörper dienende Kugel 40 vorgesehen. Die Kugel 40 wird durch die Feder 38 auf einen von einem Abschlusselement 42 gebildeten Ventilsitz 44 gedrückt (vgl. Fig. 2). Das Abschlusselement 42 ist rastend in dem Köper 66 des Ventilgliedes 26 an dessen stromaufwärts liegendem Ende eingesetzt. Das Abschlusselement 42 besitzt eine Bohrung 46, die die Kammer 36 des Ventilgliedes mit der Kammer 20 des Ventilgehäuses verbindet.In the valve housing 14, a valve member 26 is arranged, which has a mouth portion 28. The mouth portion 28 widens in the valve member consists of an elongated body 66 which forms the outlet channel, and a closure element 42. The valve member 26 has below the mouth portion 28 has a transverse bore 32 through which the medium to be discharged enters the valve member , Upstream of the mouth portion 28, two connecting channels 34 are shown in the illustrated embodiment, which connect the mouth portion with a chamber 36. In the chamber 36 of the valve member, a spring 38 and serving as a valve body ball 40 is provided. The ball 40 is pressed by the spring 38 onto a valve seat 44 formed by a closing element 42 (cf. Fig. 2 ). The end member 42 is latchingly inserted in the body 66 of the valve member 26 at its upstream end. The end member 42 has a bore 46 which connects the chamber 36 of the valve member with the chamber 20 of the valve housing.

Die Kammer 20 in dem Ventilgehäuse 14 steht über einen Ringspalt 48 (vgl. Fig. 2) mit einer Austrittskammer 50 in Verbindung. Das stromabwärts liegende Ende der Austrittskammer 50 wird durch ein Dichtelement 52 verschlossen, das in einer Aussparung 64 des Ventilgehäuses 14 angeordnet ist und durch den Ventilteller 12 in diesem gehalten wird. Das Dichtelement 52 besitzt einen Ringkörper 54, der in eine Dichtlippe 56 übergeht. Zwischen Dichtlippe 56 und Ringkörper 54 befindet sich eine umlaufende Vertiefung 58, die eine elastische Verformung der Dichtlippe 56 in radialer Richtung erlaubt. Bei dem Ventilgehäuse 14 sind Austrittskammer 50, Ringspalt 48, Kammer 20 Bestandteile des Kanals 18. Ebenso sind bei dem Ventilglied Bohrung 46, Kammer 36, Verbindungskanal 34 und Mündungsabschnitt 28 Bestandteile des sich durch das Ventilglied erstreckenden Kanals.The chamber 20 in the valve housing 14 is connected via an annular gap 48 (see. Fig. 2 ) in communication with an exit chamber 50. The downstream end of the outlet chamber 50 is closed by a sealing element 52 which is arranged in a recess 64 of the valve housing 14 and is held by the valve plate 12 therein. The sealing element 52 has an annular body 54, which merges into a sealing lip 56. Between Sealing lip 56 and annular body 54 is a circumferential recess 58 which allows an elastic deformation of the sealing lip 56 in the radial direction. In the valve housing 14 are outlet chamber 50, annular gap 48, chamber 20 components of the channel 18. Similarly, in the valve member bore 46, chamber 36, connecting channel 34 and mouth portion 28 are components of extending through the valve member channel.

In Fig. 1 ist das erfindungsgemäße Ventil in seiner regulär geöffneten Position dargestellt. In der geöffneten Position ist die Querbohrung 32 nicht durch die Dichtlippe 56 abgedichtet, sondern befindet sich in der Austrittskammer 50. Die Austrittskammer 50 wird über den Ringspalt 48, die Kammer 20 und den Austrittskanal 18 mit Medium versorgt. Um das Ventil in die in Fig. 1 dargestellte geöffnete Position zu bringen, wird das Ventilglied 26 gegen die Kraft der Feder 24 in das Ventilgehäuse 14 gedrückt. Die Bewegung des Ventilgliedes 26 in dem Ventilgehäuse wird durch die Schulter 62 in dem Ventilgehäuse begrenzt. Die Schulter 62 befindet sich am stromabwärts liegenden Ende der Kammer 20. Hierdurch wandert die Querbohrung 32 in dem Ventilglied nach innen und wird von der Dichtlippe 56 freigegeben. Das unter Druck stehende Medium tritt dann über den Austrittskanal 18 und die Kammer 20 an dem Ventilglied vorbei über die Querbohrung 32 in den Mündungsabschnitt 28 ein.In Fig. 1 the valve according to the invention is shown in its regular open position. In the open position, the transverse bore 32 is not sealed by the sealing lip 56, but is located in the outlet chamber 50. The outlet chamber 50 is supplied via the annular gap 48, the chamber 20 and the outlet channel 18 with medium. To put the valve in the in Fig. 1 To bring the illustrated open position, the valve member 26 is pressed against the force of the spring 24 in the valve housing 14. The movement of the valve member 26 in the valve housing is limited by the shoulder 62 in the valve housing. The shoulder 62 is located at the downstream end of the chamber 20. As a result, the transverse bore 32 moves inwardly in the valve member and is released by the sealing lip 56. The pressurized medium then passes via the outlet channel 18 and the chamber 20 past the valve member via the transverse bore 32 in the mouth portion 28 a.

Das Ventilglied 26 kann beispielsweise durch einen Sprühkopf oder dergleichen in das Ventilgehäuse gedrückt werden, um so das Medium austreten zu lassen.The valve member 26 may be pressed by a spray head or the like into the valve housing, for example, so as to allow the medium to escape.

In seiner geschlossenen Position, also in seiner vorgeschobenen Position wird das Ventilglied 26 so weit vorgeschoben, bis die an der Außenseite des Ventilgliedes vorgesehenen Vorsprünge 60 an die Unterkante der Dichtlippe 56 anstoßen. In dieser Position befindet sich die Querbohrung entweder noch im Bereich der Dichtlippe 56 und wird durch diese abgedichtet oder die Querbohrung ist über diese hinaus aus dem Ventilgehäuse geschoben. Die Vertiefung 58 an dem Dichtelement 52 unterstützt zusätzlich die dichtende Anlage der Dichtlippe 56 an der Außenwand des Ventilgliedes 26. Das in Kammer 50 unter Druck stehende Medium tritt ebenfalls in die Vertiefung 58 des Dichtelements 52 ein und drückt die Dichtlippe 56 gegen das Ventilglied 26.In its closed position, ie in its advanced position, the valve member 26 is advanced so far, provided on the outside of the valve member projections 60 abut the lower edge of the sealing lip 56. In this position, the transverse bore is either still in the region of the sealing lip 56 and is sealed by this or the transverse bore is pushed beyond this out of the valve housing. The depression 58 on the sealing element 52 additionally assists the sealing engagement of the sealing lip 56 on the outer wall of the valve member 26. The medium under pressure in the chamber 50 likewise enters the depression 58 of the sealing element 52 and presses the sealing lip 56 against the valve member 26.

Steigt der Druck im Behälterinnenraum über einen vorbestimmten Wert hinaus an, so drückt das Medium durch die Bohrung 46 in dem Abschlusselement 42 gegen den Ventilkörper 40. Wie in Fign. 3 und 4 dargestellt, hebt der Ventilkörper 40 sich aus seinem Dichtsitz 44 gegen die Kraft der Feder 38 an. Das Medium tritt an dem Ventilkörper vorbei in die Kammer 36 des Ventilgliedes und über die Verbindungskanäle 34 in den Mündungsabschnitt 28 ein, um über den Austrittskanal 30 auszutreten. Der Austritt des Mediums erfolgt so lange wie der Überdruck in der Bohrung 46 und damit im Behälterinnenraum groß genug ist, um den Ventilkörper 40 aus seinem Dichtsitz 44 zu heben. Ein besonderer Vorteil bei dem erfindungsgemäßen Ventil ist, dass das Medium bei einem auftretenden Überdruck zentral durch das Ventilglied geführt wird, so dass bei Überdruck der Druck in der Austrittskammer 50 und insbesondere an dem Dichtelement 52 geringer ist als an der Eintrittsöffnung 16. Es ist also möglich, die Austrittskammer 50 und das Dichtelement 52 für einen gewissen Druck zu dimensionieren und über die Feder 38 zusammen mit dem Ventilkörper 40 sicherzustellen, dass ein höherer Druck bereits stromaufwärts von der Kammer 50 austreten kann. Die Verwendung von zwei unterschiedlichen Austrittswegen für das Medium bei Überdruck und bei Normalbetrieb erlaubt es, den Überdruck, bei dem das Ventil öffnet, relativ frei zu wählen.If the pressure in the container interior increases beyond a predetermined value, the medium presses through the bore 46 in the closure element 42 against the valve body 40 FIGS. 3 and 4 shown, the valve body 40 lifts from its sealing seat 44 against the force of the spring 38 at. The medium passes past the valve body into the chamber 36 of the valve member and via the connecting channels 34 in the Mouth section 28 to exit via the outlet channel 30. The discharge of the medium takes place as long as the overpressure in the bore 46 and thus in the container interior is large enough to lift the valve body 40 from its sealing seat 44. A particular advantage of the valve according to the invention is that the medium is guided centrally through the valve member at an overpressure occurring, so that at overpressure the pressure in the outlet chamber 50 and in particular on the sealing element 52 is less than at the inlet opening 16. It is therefore it is possible to dimension the exit chamber 50 and the sealing element 52 for a certain pressure and to ensure, via the spring 38 together with the valve body 40, that a higher pressure can already escape from the chamber 50 upstream. The use of two different discharge paths for the medium at overpressure and during normal operation makes it possible to choose the overpressure at which the valve opens relatively freely.
