Abstract

A brass-wind instrument has a valve mechanism whose slides can be switched on and off by pistons which can rotate in valve bodies. The brass-wind instrument is characterised in that each piston and its surrounding valve body are united in a prefabricated part that can be inserted and retained in a valve reception housing provided in the valve mechanism.

Description

Die Erfindung betrifft Blechblasinstrumente mit einer Zylindermaschine, deren Züge durch in Ventilteilen drehbaren Wechseln ein- und ausschaltbar sind. Hierzu sind im wesentlichen die Trompeten, Flügelhörner, Alt- und Tenorhörner,die Barytone, Ventilposaunen, Waldhörner, Doppelhörner, Pistone und Tuben zu rechnen. Bei diesen Instrumenten wird die durch Anblasen erzeugte Höhe des Naturtones des Instrumentes mit Hilfe einer Mechanik, durch die ein längeres oder kürzeres Rohrstück,der sogenannte Zug, von fester Länge, in die Schallröhre des Blasinstrumentes ein- oder ausgeschaltet wird, verändert. Die Mechanik wird durch Fingerdruck auf einen unter Federspannung stehenden Drücker betätigt, der seinerseits über ein Hebelgestänge die Drehung eines mit entsprechenden Öffnungen versehenen Körpers, des sogenannten Wechsels in einem diesen umgebenden Ventilteil bewirkt.Hierwird der sogenannte Zug eingeschaltet, der die Naturtöne erniedrigt. Durch die Verwendung mehrerer Ventile läßt sich somit erreichen, daß die Lücken zwischen den Naturtönen des Instrumentes durch entsprechende Halbtöne ausgefüllt werden.The invention relates to brass instruments with a Cylinder machine, whose trains by rotating in valve parts Switch can be switched on and off. This is essentially the trumpets, flugelhorns, alto and tenor horns, the Barytones, valve trombones, French horns, double horns, pistons and Tubes to count. With these instruments, the is by blowing generated height of the natural tone of the instrument with Help a mechanic through which a longer or shorter Pipe piece, the so-called train, of fixed length, into the sound tube the wind instrument is switched on or off, changed. The mechanics is by finger pressure on you spring-loaded pusher operated, which in turn via a lever linkage the rotation of one with corresponding Openings provided body, the so-called Changes in a valve part surrounding it the so-called train switched on, which is the natural tones decreased. By using multiple valves thus achieve that the gaps between the natural tones of the Instrument must be filled in with appropriate semitones.

Bei den herkömmlichen Instrumenten sind drei oder mehr Ventile in die Maschine integriert.Jedes Ventil umfaßt einen Hohlzylinder mit kreisförmigem Außenquerschnitt, dessen Mantelfläche Öffnungen für den Anschluß von Verbindungsstutzen, die zu den Zügen des Instrumentes führen, aufweist. Durch Verdrehen jedes in dem Hohlzylinder verschwenkbaren Wechsels werden die zugehörigen Züge in die Schallröhre des Instrumentes zur Veränderung des Naturtones eingeschaltet.In the conventional instruments there are three or more Valves integrated into the machine. Each valve includes one Hollow cylinder with a circular outer cross section, the Lateral surface openings for the connection of connecting pieces, leading to the trains of the instrument. By rotating each pivotable in the hollow cylinder The associated trains alternate into the sound tube of the Instrument for changing the natural tone switched on.

Die verschwenkbaren Wechsel umfassen eine Metallachse, die mit der Längsmittelachse des Hohlzylinders fluchtet und dessen Deckfläche durchdringt, um an seinem über die Deckfläche hinausragenden Ende mit einem Hebelgestänge verbunden zu werden, welches den auf eine Drückertaste ausgeübten Fingerdruck des Spielers auf den Wechsel überträgt und diesen zu einer Drehbewegung im Hohlzylinder veranlaßt. Die Form jedes Wechsels und die Form der Ausnehmung des ihn umgebenden Hohlzylinders müssen so aufeinander abgestimmt sein, daß zwischen Wechsel und der Innenwandung des Hohlzylinders nur ein geringes Spiel vorliegt, d.h. daß die Mantelfläche des Wechsels bei Drehung in dem Hohlzylinder längs dessen Innenwandung gleitet, doch die Berührung der benachbarten, sich gegenüberliegenden Flächenbereiche so gering ist, daß bei Verschlußstellung des Ventils keine Luft durch das Ventil hindurchgelangen kann.The pivoting bills include a metal axis that aligned with the longitudinal central axis of the hollow cylinder and whose top surface penetrates to at its over the top surface protruding end connected with a lever linkage to become the one exercised on a pusher button Transfers the player's finger pressure to the change and this causes a rotary movement in the hollow cylinder. The Shape of each change and the shape of the recess of it surrounding hollow cylinders must be coordinated be that between the change and the inner wall of the Hollow cylinder has little play, i.e. that the Shell surface of the change when rotating in the hollow cylinder slides along its inner wall, but the touch of the adjacent, opposite surface areas so is small that when the valve is closed, no air can get through the valve.

Dies bedeutet aber, daß Hohlzylinder und Wechsel sehr genau aufeinander abgestimmt sein müssen. Diese Abstimmung, die in einem genauen Einschleifen der ineinander sitzenden Teile besteht, kann erst unmittelbar vor der endgültigen Fertigstellung des Instrumentes durchgeführt werden, da die Hohlzylinder fest mit der Maschine verbunden sind. Hierdurch leidet natürlich die erreichbare Paßgenauigkeit der Wechsel in den Hohlkörpern. Falls es notwendig sein sollte, die Paßgenauigkeit doch noch zu verbessern, kann dies nachträglich nur noch durch vollständigen Ausbau und Ersatz des Wechsels erfolgen. However, this means that hollow cylinders and exchanges are very accurate must be coordinated. This vote that in a precise grinding of the parts sitting in each other exists only immediately before the final Completion of the instrument can be carried out as the Hollow cylinders are firmly connected to the machine. hereby the achievable fit of the changes naturally suffers in the hollow bodies. If necessary, the This can improve the fit subsequently only through complete removal and replacement of change.

Der Erfinder hat sich nun die Aufgabe gestellt, ein Blechblasinstrument zu schaffen, das gegenüber den herkömmlichen Instrumenten eine größere Paßgenauigkeit der Ventile und darüber hinaus eine höhere Wartungsfreundlichkeit aufweist.The inventor has now set himself the task of a brass instrument to create that over the conventional Instruments a greater fit of the valves and also has a higher ease of maintenance.

Erfindungsgemäß wird dies bei einem Blechblasinstrument der vorstehend genannten Gattung dadurch erreicht, daß jeder Wechsel und das ihn umgebende Ventilteil in einem vorgefertigten Bauteil vereinigt, in ein in der Zylindermaschine vorgesehenes Aufnahmegehäuse einsetzbar und arretierbar ist.According to the invention this is the case with a brass instrument the aforementioned genus achieved in that each Change and the surrounding valve part in one prefabricated component combined into one in the cylinder machine The intended housing can be used and locked is.

Ferner ist Gegenstand der Anmeldung ein Bauteil für Zylindermaschinen eines Blechblasinstrumentes, das dadurch gekennzeichnet ist, daß ein in herkömmlicher Weise ausgebildeter Wechsel in ein Ventilteil eingesetzt und mit diesem zu einer Einheit verbunden ist, wobei das Ventilteil in Form eines Hohlkörpers ausgebildet ist, dessen Innenwand der Außenwand des Wechsels angepaßt ist und in dessen Mantelfläche diese durchdringende Öffnungen vorgesehen sind, deren Durchmesser mit den im Wechsel vorgesehenen Ausnehmungen koordiniert sind. The application also includes a component for Cylinder machines of a brass instrument, the result is characterized in that a trained in a conventional manner Change used in a valve part and with it is connected to a unit, the valve part in the form a hollow body is formed, the inner wall of the Outside wall of the bill is adjusted and in it Lateral surface of these penetrating openings are provided, their diameter with the alternating recesses are coordinated.

Durch die erfindungsgemäß geschaffene Möglichkeit, einen Wechsel mit dem ihn umgebenden Ventilteil als vorgefertigtes Bauteil in ein im praktisch fertiggestellten Blasinstrument enthaltenes Ventilaufnahmegehäuse einsetzen zu können, sind zahlreiche Vorteile geschaffen, die sowohl im Rahmen der Fertigung der Instrumente als auch beim Gebrauch dieser Instrumente zum Tragen kommen.
Wie eingangs bereits erwähnt, muß jeder Wechsel genau auf seinen ihn umgebenden Ventilteil eingeschliffen sein, um einerseits die Reibung zwischen den sich gegenüberliegenden Mantelflächen beider Teile gering zu halten und um andererseits aber auch zu verhindern, daß unerwünschte Nebenluft in die Maschine gelangen kann.
The possibility created according to the invention of being able to use a change with the valve part surrounding it as a prefabricated component in a valve receptacle housing contained in the practically finished wind instrument creates numerous advantages which come into play both in the course of the manufacture of the instruments and in the use of these instruments ,
As already mentioned at the beginning, each change must be ground precisely on its surrounding valve part, on the one hand to keep the friction between the opposing lateral surfaces of both parts low and on the other hand to prevent undesired secondary air from getting into the machine.

Dieser Einschleifvorgang, welcher eine hohe Genauigkeit erfordert, kann nunmehr an dem vom Instrument getrennten Bauteil vorgenommen werden. Hierbei ist ständig eine Sichtprüfung möglich, die jedoch bei den herkömmlichen Instrumenten, bei denen der Wechsel in das mit Instrument integrierte Ventilteil, Hohlzylinder eingebaut werden muß, nicht mehr durchgeführt werden kann. Somit ist mit Hilfe des vorgefertigten Bauteiles eine höhere Justiergenauigkeit erreichbar.Ein weiterer Vorteil liegt darin, daß das Bauteil unabhängig von dem Instrument gefertigt wird und bei der Endmontage nur noch in das fertiggestellte Instrument einfach eingesetzt werden muß.
Damit entfallen die bisher die Herstellung eines Instrumentes erschwerenden Einschleiferfordernisse des bisher fest im Instrument eingebauten Ventilteiles, da für das Ventilaufnahmegehäuse jetzt keine kritischen Maßtoleranzen mehr beachtet werden müssen. Der letzte Arbeitsschritt ist daher sehr einfach und kann in kürzester Zeit erfolgen, da es sich nur noch um eine reine Montagetätigkeit handelt, denn an den einzusetzenden Bauteilen in Form vollständiger Ventile braucht nichts mehr geändert zu werden.
This grinding process, which requires a high degree of accuracy, can now be carried out on the component separate from the instrument. In this case, a visual inspection is always possible, but this can no longer be carried out with the conventional instruments in which the change to the valve part integrated into the instrument, hollow cylinder, has to be installed. Thus, a higher adjustment accuracy can be achieved with the help of the prefabricated component. Another advantage is that the component is manufactured independently of the instrument and only has to be inserted into the finished instrument during final assembly.
This eliminates the grinding-in requirements of the valve part, which was previously built into the instrument, which made the manufacture of an instrument difficult, since critical dimension tolerances no longer have to be observed for the valve receiving housing. The last step is therefore very simple and can be carried out in the shortest possible time, since it is only a matter of assembly work, because nothing needs to be changed in the components to be used in the form of complete valves.

Ein weiterer Vorteil ergibt sich schließlich daraus, daß natürlich die Bauteile in Form vollständiger Ventile nicht nur bei der Montage ohne Schwierigkeiten eingesetzt werden können, sondern, da diese Ventile eigenständige Bauteile sind, können diese auch zum Austausch aus dem Instrument herausgenommen und durch neue Ventile ersetzt werden. Hierdurch ist es möglich, verschlissene oder auch fehlerhafte Ventile einfach durch neue Ventile zu ersetzen. Dies macht sich besonders für Musiker günstig bemerkbar, da ihnen die Möglichkeit gegeben ist, die Ventile nach längerem Spielen erneut zu ölen und selbst zu reinigen, indem sie die Ventile als ganzes aus dem Instrument ausbauen, ohne Gefahr zu laufen, daß Justierungen zwischen Wechsel und Ventilkörper erneut vorgenommen werden müßten. Another advantage results from the fact that of course not the components in the form of complete valves can only be used during assembly without difficulty can, but because these valves are independent components they can also be exchanged from the instrument removed and replaced with new valves. This makes it possible to find worn or faulty ones Easy to replace valves with new valves. This makes itself felt particularly favorably for musicians, because they the possibility is given to the valves after a long time Play oil again and clean yourself by using the Remove valves as a whole from the instrument, without danger to run adjustments between bills of exchange and Valve body would have to be made again.

Da erfahrungsgemäß insbesondere die Ventilteile durch den häufigen Gebrauch einer mechanischen Abnutzung unterliegen, ist es für jeden Benutzer eines Blechblasinstrumentes nun möglich, sich selbst die erforderlichen neuen Ventile zu beschaffen und auch selbst wieder in das Instrument einzubauen.Since experience has shown that especially the valve parts by the frequent use are subject to mechanical wear, it is now for every user of a brass instrument possible to give yourself the necessary new valves and get it back into the instrument install.

Darüber hinaus ist es möglich, für die Bauteile solche Materialien heranzuziehen, deren Eigenschaften hinsichtlich Verschleiß und Dichtigkeit optimal ausgewählt werden können, ohne daß das Erscheinungsbild des Instrumentes darunter leidet.In addition, it is possible for such components To use materials, their properties regarding Wear and tightness can be optimally selected without the appearance of the instrument underneath suffers.

Das Bauteil 1 umfaßt einen Wechsel 2 herkömmlicher Bauart mit einer Längsmittelachse 3, die sich in ein kreiszylindrisches Teil 4 erweitert, welches im dargestellten Beispiel mit zwei sich gegenüberliegenden Ausnehmungen 5 versehen ist, deren Form im Längsschnitt als Kreisabschnitte erkennbar ist. Aus Fig. 2a ist die Form des Wechsels 2 in einer um 90° gedrehten Stellung wiedergegeben. Hieraus läßt sich der Verlauf der als Luftkanäle dienenden Ausnehmungen 5 erkennen, die beim Spiel bei von der Hand des Spielers betätigtem Drücker (nicht dargestellt) den Wechsel 2 mit dem zugehörigen Zug verbinden.The invention shown in longitudinal section in Fig. 1 Component 1 is shown in an exploded view in FIG. 2. The component 1 comprises a change 2 of conventional design with a longitudinal central axis 3, which is in a circular cylindrical Part 4 extended, which is shown in the Example with two opposing recesses 5 is provided, whose shape in longitudinal section as circular sections is recognizable. 2a is the shape of the change 2 in a position rotated by 90 °. From this leaves the course of the recesses 5 serving as air channels recognize that when playing at the player's hand actuated pusher (not shown) change 2 with the Connect the associated train.

Im Bereich der Deck- und Bodenfläche 4a bzw. 4b des zylindrischen Teiles 4 des Wechsels 2 sind ringförmige Ausnehmungen 6a,b vorgesehen, deren Tiefe bis nahe zu den Luftkanälen 5 reicht. Durch diese Ausnehmungen 6a,b wird das Gewicht des Wechsels verringert, so daß die Betätigung des Wechsels 2 durch die Hand des Spielers leichter wird, und ein schnelleres Spiel bei geringerer Ermüdung der Hand des Spielers erreicht wird. In the area of the top and bottom surfaces 4a and 4b of the cylindrical part 4 of the change 2 are annular Recesses 6a, b are provided, the depth of which is close to Air channels 5 is enough. Through these recesses 6a, b Weight of the change is reduced, so that the actuation of the Switch 2 becomes easier by the player's hand, and a faster game with less hand fatigue Player is reached.

Die Längsmittelachse 3 des Wechsels ragt mit ihrem oberen Ende 3a, dem Wechselstift, weit über den zylindrischen Teil 4 hinaus. Das Ende 3a wird über einen in ein Innengewinde des Endes 3a geschraubten Schwenkhebel, den sogenannten Flügel 40 mit dem Hebelgestänge (nicht dargestellt), welches zu dem Drücker des Instrumentes führt, verbunden. Das untere Ende 3b der Längsmittelachse 3 dient der Justierung und Lagerung des Wechsels 2.The longitudinal central axis 3 of the change protrudes with its upper one End 3a, the change pin, far above the cylindrical part 4 beyond. The end 3a is in an internal thread of the end 3a screwed pivot lever, the so-called Wing 40 with the lever linkage (not shown), which leads to the pusher of the instrument, connected. The lower End 3b of the longitudinal central axis 3 is used for adjustment and Storage of bills of exchange 2.

Ein Ventilteil 9 ist hier als kreiszylindrischer Hohlkörper ausgebildet, in dessen Mantel 10 vier, je zwei sich gegenüberliegende, kreisförmige Bohrungen 11 vorgesehen sind. Der Durchmesser dieser Bohrungen 11 entspricht bei der hier beschriebenen Ausführung genau dem Durchmesser, des Kreisausschnittes der Ausnehmungen 5 des Wechsels 2. Die Höhe des Mantels 10 des Ventilteils 9 ist so bemessen, daß bei in das Ventilteil 9 eingesetztem Wechsel 2 die Öffnungen 11 sich mit den Ausnehmungen 5 des Wechsels 2 decken. Die lichte Weite des Ventilteils 9 ist nur geringfügig größer als der quer verlaufende Durchmesser des Wechsels 2, so daß dieser mit nur geringer Reibung in dem Ventilteil 9 drehbar ist. A valve part 9 is here as a circular cylindrical hollow body trained in the coat 10 four, two each opposite circular bores 11 are provided are. The diameter of these holes 11 corresponds to the Execution described here exactly the diameter of the Circular section of the recesses 5 of the change 2. Die The height of the jacket 10 of the valve part 9 is such that with change 2 inserted into the valve part 9, the openings 11 coincide with the recesses 5 of the change 2.

Der Einschleifvorgang kann dann an den beiden Bauteilen 2 und 9 mit großer Genauigkeit durchgeführt werden, da, solange diese beiden ineinander geschobenen Bauteile 2 und 9 noch nicht in das Instrument eingebaut sind, immer noch eine Sichtprüfung möglich ist und sich eine entsprechende Nachbesserung ohne Schwierigkeiten vornehmen läßt. Die unabhängig vom Instrument fertiggestellte Baugruppe 2,9,18 kann dann in das im Instrument integrierte Ventilaufnahmegehäuse 16 eingesetzt werden. Diese Montage wird bei der im Beispiel gezeigten Ausführung von oben durchgeführt. Unterhalb des Deckels 12 befindet sich am Zylindermantel 10 ein Justierstift 19. Dieser wird in eine entsprechende Ausnehmung 20 im Ventilaufnahmegehäuse 16 eingelassen. Das untere, das Gewinde 14 aufweisende Ende des Ventilteils 9 ragt nach dem Einsetzen der miteinander verbundenen Bauteile 2,9 und 18 nach unten aus dem Ventilaufnahmegehäuse 16 heraus, so daß das Innengewinde 15 des Schraubdeckels 8 mit dem Außengewinde 14 des Ventilteils 9 verschraubt werden kann. Hierbei greift ein über den Sprengdeckel 18 hinausragender Abschnitt des Lagerstiftes in das Sackloch 7 des Schraubdeckels 8 ein. The change 2 is inserted exactly into the valve part 9. The detonator cover 18 serves as the lower bearing seat of the Wechsels 2. The grinding process can then be carried out on the two Components 2 and 9 performed with great accuracy be there as long as these two are pushed into each other Components 2 and 9 have not yet been installed in the instrument are, a visual inspection is still possible and one carry out appropriate rework without difficulty leaves. The one completed regardless of the instrument Assembly 2,9,18 can then be integrated in the instrument Valve housing 16 are used. This montage is from above in the embodiment shown in the example carried out. Below the lid 12 is on Cylinder jacket 10 an adjusting pin 19. This is in a corresponding recess 20 in the valve receptacle housing 16 admitted. The lower end of the thread 14 Valve part 9 protrudes after the insertion of each other connected components 2,9 and 18 down from the Valve holder housing 16 out, so that the internal thread 15th of the screw cap 8 with the external thread 14 of the valve part 9 can be screwed. This intervenes over the Detonator cap 18 protruding portion of the bearing pin into the blind hole 7 of the screw cap 8.

Auf die nach oben ragende Führungsbüchse 13 des Ventilteiles 9 wird nach dem Einsetzen der Kombination der Teile 2,9,18 und 8 ein in Form eines Hufeisens ausgebildetes Teil 41 auf die Deckseite 12 des Ventilteiles 9 aufgeschraubt, das als Endanschlag für den über das Hebelgestänge verdrehbaren Flügel 40 dient.On the upwardly projecting guide sleeve 13 of the valve part 9 becomes after inserting the combination of parts 2,9,18 and 8 a part 41 in the form of a horseshoe screwed on the top side 12 of the valve part 9, which as End stop for the one that can be rotated via the lever linkage Wing 40 is used.

Da es sich bei dem erfindungsgemäßen Bauteil 1, umfassend das Ventilteil 9 mit Wechsel 2 und Sprengdeckel 18, um ein voll funktionsfähiges Ventil handelt, das in einfacher Weise von jedermann in das fertige Instrument eingebaut werden kann, ohne daß weitere Justiertätigkeiten vorgenommen werden müssen, ist es vor allem auch für den Spieler des Instrumentes möglich, das Ventil zur Reinigung oder zum Ölen selbst aus- und einzubauen.Since the component 1 according to the invention is comprehensive the valve part 9 with change 2 and detonator cover 18 to one fully functional valve that acts in a simple manner can be built into the finished instrument by everyone can be carried out without further adjustment activities it is especially for the player of the Instrumentes possible, the valve for cleaning or oiling remove and install yourself.

Die für einen Ausbau des erfindungsgemäßen Bauteils 1 erforderlichen Schritte sind in den Fig. 4a bis 4e gezeigt.The for an expansion of the component 1 according to the invention required steps are shown in Figs. 4a to 4e.

In Fig.4a ist das in das Ventilaufnahmegehäuse 9 eingebaute Bauteil 1 ohne die Teile 40 und 41 gezeigt. Zunächst wird der Schraubdeckel 8 abgeschraubt, Fig. 4b, dann werden die Bauteile 2 und 9 mit Sprengdeckel 18 nach oben aus dem Ventilaufnahmegehäuse 16 herausgezogen, Fig. 4c. Nachdem der mit Preßpassung im Ventilteil 9 sitzende Sprengdeckel 18 entfernt ist, kann der Wechsel 2 aus dem Ventilteil 9 herausgezogen werden.In Fig.4a that is built into the valve housing 9 Component 1 shown without parts 40 and 41. First of all unscrewed the screw cap 8, Fig. 4b, then the Components 2 and 9 with snap lid 18 upwards from the Valve holder housing 16 pulled out, Fig. 4c. After this the detonating cover 18 seated in the valve part 9 with an interference fit is removed, the change 2 from the valve part 9 be pulled out.

In den Fig. 5 bis 7 sind Bauteile 30 dargestellt, die denen der Fig. 1 bis 3 weitgehend entsprechen. Der Unterschied liegt allein darin, daß diese Bauteile 30 nicht von oben her, sondern von unten nach oben in ihre Ventilaufnahmegehäuse 31 eingeschoben werden.5 to 7, components 30 are shown, which 1 to 3 largely correspond. The difference lies solely in the fact that these components 30 are not from above forth, but from the bottom up in their valve housing 31 can be inserted.

Die Unterschiede dieser Bauteile 30 lassen sich am besten aus der Explosionsdarstellung nach Fig. 6 erkennen.The differences between these components 30 can best be explained 6 from the exploded view.

Der Wechsel stimmt vollständig mit dem Wechsel 2 nach Fig. 2 überein und braucht daher nicht näher beschrieben zu werden. Das gleiche gilt auch für den Sprengdeckel 18. Das Ventilteil 32 weist aber durch die andere Montage bedingte geringfügige Unterschiede gegenüber dem Ventilteil 9 auf. Der Außenrand des mit dem Mantel 33 einstückigen Deckels 34 schließt mit der Mantellinie ab, d.h. der Deckel 34 ragt nicht seitlich über den zylindrischen Teil des Ventilteiles 32 hinaus. Im Bereich des oberen Randes des zylindrischen Mantels 33 ist ein Außengewinde 35 vorgesehen, auf das nach dem Einsetzen des Ventilteiles 32 in das Ventilaufnahmegehäuse 31 ein Schraubring 37 aufgeschraubt wird. Im unteren Randbereich des Zylindermantels 33 ist nach außen ragend der Justierstift 38 vorgesehen, der in eine entsprechende Ausnehmung 36 des Ventilaufnahmeghäuses 31 eingreift, um den genauen Paßsitz des Bauteiles 30, umfassend das Ventilteil 32 mit dem Wechsel 2 und dem Sprengdeckel 18 im Ventilaufnahmegehäuse 31 zu gewährleisten.The change is completely correct with the change 2 according to FIG. 2 agree and therefore need not be described in more detail. The same applies to the detonator cover 18. The Valve part 32 has due to the other assembly slight differences compared to the valve part 9. The outer edge of the cover 34 integral with the jacket 33 closes with the generatrix, i.e. the cover 34 protrudes not laterally over the cylindrical part of the valve part 32 beyond. In the area of the upper edge of the cylindrical Sheath 33, an external thread 35 is provided, after which the insertion of the valve member 32 into the valve housing 31 a screw ring 37 is screwed on. At the bottom The edge region of the cylinder jacket 33 protrudes outwards Adjustment pin 38 is provided, which in a corresponding Recess 36 of the valve housing 31 engages to the exact fit of the component 30, including the valve part 32 with the change 2 and the detonator cover 18 in the valve housing 31 to ensure.

Bei dieser Ausbildung des Bauteiles 30 sind selbstverständlich die zu einem Ventilsatz vereinigten Aufnahmegehäuse 31 miteinander verbunden, siehe Fig. 7 und sind in übereinstimmender Konstruktion ausgeführt. Sämtliche Ventile 30 werden dann von unten nach oben in die Ventilaufnahmegehäuse 31 eingeschoben und von oben mit Hilfe der Schraubringe 37 befestigt.With this configuration of component 30, it goes without saying the receptacle housings 31 combined to form a valve set interconnected, see Fig. 7 and are in agreement Construction carried out. All valves 30 are then from bottom to top in the valve housing 31 inserted and from above using the screw rings 37 attached.

Die einzelnen Schritte, die für einen Ausbau einer solchen Baugruppe erforderlich sind, sind in den Fig. 8a bis 8f dargestellt.The individual steps for expanding such Assembly are required are shown in Figs. 8a to 8f.

Zunächst wird der Schraubring 37 entfernt, dann können die Bauteile 8,18,32 und 2 nach unten aus dem Ventilaufnahmegehäuse 31 herausgezogen werden (Fig.8c). Nachdem der Schraubdeckel 8 und der Sprengring 18 abgezogen sind, ist es möglich, den Wechsel 2 für eine eventuell erforderliche gründliche Reinigung und Überprüfung herauszunehmen.First the screw ring 37 is removed, then the Components 8, 18, 32 and 2 downwards out of the valve housing 31 are pulled out (Fig. 8c). After the Screw cap 8 and the snap ring 18 are removed, it is possible to change 2 for a possibly required take out thorough cleaning and inspection.
