Description

Die Erfindung betrifft einen Druckgasbehälter für Gasdruck-Sportwaffen, bestehend aus einem Rohr, das an einem Ende einen eingezogenen Boden bildet und am anderen Ende einen mit einem sich beim Anschrauben des Behälters an die Waffe öffnenden Ventil ausgestatteten Verschlußkopf aufweist.The invention relates to a compressed gas container for gas pressure sports weapons, consisting of a tube which forms a retracted base at one end and has a breech head equipped with a valve which opens when the container is screwed onto the weapon.

In der Regel besitzt die betreffende Waffe, und zwar eine Pistole oder ein Gewehr zum Anschrauben des Druckgasbehälters, insbesondere CO₂-Behälters, einen Schraubansatz, der in Achsrichtung durchbohrt ist, wobei die Bohrung in eine Druckkammer einmündet, die über einen durch ein Ventil verschlossenen Kanal mit dem Lauf der Waffe hinter der Patrone verbunden ist. Beim Aufschrauben des Druckgasbehälters bzw. CO₂-Behälters auf den Schraubansatz drückt dieser über einen Stift das Ventil im Verschlußkopf des Behälters von seinem Sitz, so daß das Druckgas in die Druckkammer der Waffe überströmt und sich dort der gleiche Druck wie im Behälter einstellt.Das den zum Lauf führenden Kanal verschließende Ventil wird bei Betätigung der Abzugvorrichtung der Waffe mittels eines Schlagstiftes od. dgl. kurzzeitig geöffnet, so daß das Druckgas durch den Kanal zum Geschoß gelangen kann.In general, the weapon in question, namely a pistol or a rifle for screwing on the compressed gas container, in particular a CO₂ container, has a screw attachment which is pierced in the axial direction, the bore opening into a pressure chamber which is closed by a valve through a channel connected to the barrel of the weapon behind the cartridge. When screwing the pressurized gas container or CO₂ container onto the screw attachment, this presses the valve in the closure head of the container from its seat via a pin, so that the compressed gas flows into the pressure chamber of the weapon and the same pressure as in the container is set there Valve closing the channel leading to the barrel is briefly opened when the trigger device of the weapon is actuated by means of a striker or the like, so that the compressed gas can reach the projectile through the channel.

Der Druckgasbehälter kann nach Entleerung selbstverständlich wieder aufgefüllt werden. Aufgrund der physikalischen Eigenschaften ändert sich aber der Druck im Druckgasbehälter in Abhängigkeit von der Temperatur und dem Füllungsgrad mit Druckgas bzw. CO₂. Bei einem Füllgrad von etwa 50 % und bei einer Temperatur von ungefähr 20° C herrscht im Behälter ein Druck von etwa 60 bar. Dieser Druck herrscht nach dem Aufschrauben des Behälters auf die Waffe, auch in deren Druckkammer. Wenn nun der Druck im Behälter aufgrund Überfüllung und/oder zu hoher Temperatur ansteigt, die Energie des auf den Schlagstift einwirkenden Schlagstückes der Waffe aber gleichbleibt, ändert sich die jeweils freigegebene Druckgasmenge, wodurch selbstverständlich die Geschwindigkeit des Geschoßes beeinflußt wird, was wieder ungünstige Rückwirkungen auf die Genauigkeit des Schusses haben kann. Bisher wird versucht, diesem Sachverhalt dadurch Rechnung zu tragen, daß nach dem Füllen des Druckgasbehälters das genaue Füllgewicht ermittelt, durch Abblasen des überschüssigen Druckgases eingestellt wird und darauf geachtet wird, daß die Temperatur beim Schließen möglichst konstant bleibt. Das Abwiegen und Abblasen lassen ist aber verhältnismäßig umständlich und es ist auch nicht immer möglich, eine Temperaturkonstanz beizubehalten.The compressed gas tank can of course be refilled after emptying. Due to the physical properties, however, the pressure in the pressurized gas container changes with the temperature and the degree of filling Compressed gas or CO₂. At a filling level of around 50% and at a temperature of around 20 ° C, the pressure in the container is around 60 bar. This pressure prevails after the container is screwed onto the weapon, also in its pressure chamber. If the pressure in the container rises due to overfilling and / or too high a temperature, but the energy of the firing piece of the weapon acting on the firing pin remains the same, the amount of compressed gas released changes, which of course affects the speed of the projectile, which again has adverse effects can have the accuracy of the shot. So far, attempts have been made to take this fact into account by determining the exact filling weight after filling the compressed gas container, adjusting it by blowing off the excess compressed gas, and ensuring that the temperature remains as constant as possible when closing. Weighing and blowing off is relatively cumbersome and it is not always possible to maintain a constant temperature.

Dazu kommt noch, daß eine starke Überfüllung des Behälters sowie große Temperaturbelastungen die Gefahr des Berstens des Behälters mit sich bringen. Es ist zwar bereits bekannt, eine Abblasöffnung des Behälters durch eine dünne Scheibe zu verschließen, die bei Druckanstieg im Behälter über ein bestimmtes Maß zerstört wird, doch ist nach dem Ansprechen der durch eine solche Berstscheibe gebildeten Sicherheitseinrichtung der Druckgasbehälter für den Schützen unbrauchbar, d. h. er kann von ihm nicht mehr aufgefüllt werden.In addition, there is a strong overfilling of the container and high temperature loads, with the risk of the container bursting. It is already known to close a blow-off opening of the container by means of a thin disk, which is destroyed to a certain extent when the pressure in the container rises, but after the safety device formed by such a rupture disk responds, the compressed gas container is unusable for the shooter, i.e. H. it can no longer be filled by it.

Somit liegt der Erfindung die Aufgabe zugrunde, diese Mängel zu beseitigen und einen Druckgasbehälter der eingangs geschilderten Art zu schaffen, bei dem Druckschwankungen im wesentlichen vermieden werden, also kein unzulässiger Überdruck auftreten kann und der für den Schützen praktisch stets brauchbar bleibt.The invention is therefore based on the object of eliminating these deficiencies and of creating a pressurized gas container of the type described at the outset, in which pressure fluctuations are substantially avoided, that is to say no inadmissible overpressure can occur and which practically always remains useful for the shooter.

Die Erfindung löst die gestellte Aufgabe dadurch, daß ein ins Freie führendes zusätzliches Ventil vorgesehen und die Vorspannkraft der dessen Ventilkörper belastenden Feder voreinstellbar ist.The invention achieves the stated object in that an additional valve leading into the open is provided and the pretensioning force of the spring loading the valve body thereof can be preset.

Die Vorspannung der Feder des zusätzlichen Ventils wird also bei der Montage von vornherein auf das dem gewünschten Innendruck entsprechende Maß eingestellt, so daß Druckschwankungen durch selbständiges Abblasen des überschüssigen CO₂ od. dgl. in gewissen Grenzen gehalten werden können, um schließlich die Geschwindigkeit des Geschoßes möglichst gleich zu halten und die Genauigkeit der Schüsse zu steigern. Selbstverständlich wirkt das zusätzliche Ventil auch als Sicherheitseinrichtung, die den Vorteil hat, daß der Behälter nach ihrem Ansprechen funktionstüchtig bleibt. Der Wiegevorgang beim Nachfüllen des Druckgasbehälters wird zwar nicht überflüssig gemacht, doch dient dieser nur mehr zur Bestimmung der noch vorhandenen Druckgas- bzw. CO₂-Menge.The bias of the spring of the additional valve is thus set from the outset to the desired internal pressure corresponding size, so that pressure fluctuations by independent blowing off the excess CO₂ or the like. Can be kept within certain limits, in order to eventually speed the projectile as possible keep the same and increase the accuracy of the shots. Of course, the additional valve also acts as a safety device, which has the advantage that the container remains functional after it has responded. The weighing process when refilling the compressed gas container is not made superfluous, but this is only used to determine the amount of compressed gas or CO₂ still present.

Um möglichste Genauigkeit beim Öffnen und Schließen des zusätzlichen Ventils zu erreichen, besteht der Ventilkörper des zusätzlichen Ventils aus einer in einer Bohrung geführten, die Feder aufnehmenden Zylinderbüchse, deren dem Ventilsitz zugekehrter, gegebenenfalls mit einer Dichtungsauflage versehener Boden in seinem Randbereich wenigstens eine Durchtrittsöffnung ins Büchseninnere aufweist. Es wird dadurch eine sichere Führung des Ventilkörpers erreicht und eine Verkantung, die Unsicherheiten beim Schließ- bzw. Öffnungsvorgang mit sich brächte, vermieden.In order to achieve the greatest possible accuracy when opening and closing the additional valve, the valve body of the additional valve consists of a cylinder sleeve guided in a bore and accommodating the spring, the bottom of which faces the valve seat and is optionally provided with a sealing pad in its edge area at least one passage opening into the interior of the sleeve having. This results in a secure guidance of the valve body and prevents canting, which would result in uncertainties during the closing or opening process.

Aus dem gleichen Grunde ist dem Ventilsitz des zusätzlichen Ventils zum Behälterinneren hin ein Filter vorgeordnet, so daß keine Staubteilchen od. dgl. auf den Ventilsitz gelangen können.For the same reason, a filter is arranged upstream of the valve seat of the additional valve towards the interior of the container, so that no dust particles or the like can get onto the valve seat.

Das zusätzliche Ventil ist vorzugsweise im Verschlußkopf an geordnet. Es ist auch möglich, das zusätzliche Ventil als eigene in den Verschlußkopf oder Behälterboden eingeschraubte Baueinheit auszubilden, die dann leicht von vornherein auf den gewünschten Innendruck eingestellt werden kann und nur mehr in den Verschlußkopf- oder Behälterboden eingeschraubt zu werden braucht.The additional valve is preferably in the closure head orderly. It is also possible to design the additional valve as a separate unit screwed into the closure head or container bottom, which can then be easily adjusted from the outset to the desired internal pressure and only needs to be screwed into the closure head or container bottom.

Der Druckgas- bzw. CO₂-Behälter besteht aus einem Rohr 1, das an einem Ende einen eingezogenen Boden 2 bildet und am anderen Ende mit einem eingeschraubten Verschlußkopf 3 versehen ist. Der Verschlußkopf 3 besitzt ein Ventil 4, das beim Aufschrauben des Behälters auf einen Schraubansatz der Waffe, der in die Gewindebohrung 5 eindringt, über den Stift 6 durch Abheben des Ventilkörpers 7 von seinem Sitz 8 geöffnet wird.The compressed gas or CO₂ container consists of a tube 1, which forms a retracted bottom 2 at one end and is provided with a screwed-in closure head 3 at the other end. The closure head 3 has a valve 4, which is opened when the container is screwed onto a screw attachment of the weapon, which penetrates into the threaded bore 5, via the pin 6 by lifting the valve body 7 from its seat 8.

Erfindungsgemäß ist nun ein zusätzliches Ventil 9, 9a, 9b vorgesehen, das gemäß Fig. 1 in einer Bohrung des Verschlußkopfes 3 angeordnet ist. Der Ventilkörper 10 besteht aus einer in einer Bohrung 11 geführten zylindrischen Büchse, deren dem Ventilsitz 12 zugekehrter, mit einer Dichtungsauflage 13a versehener Boden 13 in seinem Randbereich zwei Durchtrittsöffnungen 14 ins Büchseninnere aufweist und eine Druckfeder 15 aufnimmt. Der Ventilsitz 12 kann zur Veränderung der Vorspannung der Feder 15 im Verschlußkörper 3 durch Verschraubung verstellt werden, wobei dem eigentlichen Ventilsitz zum Behälterinneren hin ein Filter 16 vorgeordnet ist.According to the invention, an additional valve 9, 9a, 9b is now provided, which according to FIG. 1 is arranged in a bore of the closure head 3. The valve body 10 consists of a cylindrical bushing guided in a bore 11, the bottom 13 of which, facing the valve seat 12 and provided with a sealing pad 13a, has two through openings 14 into the inside of the bushing in its edge region and receives a compression spring 15. The valve seat 12 can be adjusted to change the bias of the spring 15 in the closure body 3 by screwing, the actual one A filter 16 is arranged upstream of the valve seat towards the interior of the container.

Gemäß Fig. 2 ist das zusätzliche Ventil 9a nicht im Verschlußkopf 3 angeordnet, sondern besitzt ein eigenes zylindrisches Gehäuse 17, das im Boden 2 des Behälters eingeschraubt ist. Die Ventilfeder 15 kann in ihrer Vorspannung durch Relativverdrehung des Ventilsitzes 12 gegenüber dem Gehäuse 17 auf das gewünschte Maß voreingestellt werden.2, the additional valve 9a is not arranged in the closure head 3, but has its own cylindrical housing 17 which is screwed into the bottom 2 of the container. The valve spring 15 can be preloaded to the desired level by relative rotation of the valve seat 12 relative to the housing 17.

Wie Fig. 3 zeigt, kann das zusätzliche Ventil 9b als Baueinheit auch in den Ventilkopf 3 eingeschraubt werden, wobei der Ventilsitz 12 mit dem Gehäuse 17 einstückig ausgebildet und das Widerlager 18 der Feder 15 im Gehäuse 17 zur Veränderung der Federvorspannung schraubverstellbar ist.As shown in FIG. 3, the additional valve 9b can also be screwed into the valve head 3 as a structural unit, the valve seat 12 being formed in one piece with the housing 17 and the abutment 18 of the spring 15 in the housing 17 being screw-adjustable to change the spring preload.
