Description

Die Erfindung betrifft ein Ventilsystem für Blechblasinstrumente gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a valve system for brass instruments according to the preamble of patent claim 1.

Die Tonhöhe und Intonation beim Spiel auf Blechblasinstrumenten wie Trompeten, Hörnern, Posaunen und Tuben wird neben der Blastechnik und Lippenmodulation durch mechanische Ventile an den Instrumenten verändert, die in der Regel über federbelastete Hebel und mechanische Gelenke oder auch eine Schnurmechanik betätigbar sind. Bei Betätigung der Ventile wird die Luft im Instrument durch alternative Rohrschleifen definierter Länge geführt, um so den Naturton durch die Verlängerung des Rohrweges um einen bis drei Halbtöne erniedrigen zu können. Die beaufschlagten Ventilrohrschleifen sind in der Regel hierbei derart ausgebildet, dass zylindrische Bohrungen einen Ventil-Stimmzug zur Feinabstimmung der Ventilrohrschleifen ermöglichen.The pitch and intonation when playing on brass instruments such as trumpets, horns, trombones and tubes is changed in addition to the blowing technique and lip modulation by mechanical valves on the instruments, which are usually actuated by spring-loaded levers and mechanical joints or a string mechanism. When the valves are actuated, the air in the instrument is guided through alternative pipe loops of defined length, in order to be able to lower the natural tone by extending the pipe path by one to three semitones. The acted upon valve tube loops are usually designed in this case so that cylindrical holes allow a valve tuning for fine tuning of the valve tube loops.

Die vorliegende Erfindung bezieht sich hierbei auf ein Ventilsystem mit Drehventilen, die einen Ventilkörper mit zwei Kanälen aufweisen, der bei einem betätigen des Ventils eine Rotation um 90 Grad seiner Hochachse vornimmt und so die Umleitung der Luft in die Ventilrohrschleife durchführt. Ein derartiges Drehventil für Blechblasinstrumente ist beispielsweise offenbart in der Schrift DE 30 13 646 , wobei hier der Anspruch darauf gerichtet ist, Unstetigkeiten in der Luftführung zu verbessern.The present invention relates to a valve system with rotary valves having a valve body with two channels, which makes a rotation of 90 degrees of its vertical axis during actuation of the valve and thus performs the diversion of the air into the valve tube loop. Such a rotary valve for brass instruments is disclosed, for example, in the document DE 30 13 646 , Wherein the claim is directed to improve discontinuities in the air flow.

Weitere Drehventile sind z.B. im US Patent US 530,781 aus dem Jahr 1894 oder US 2,484,408 aus dem Jahr 1945 bekannt.Further rotary valves are eg in US Pat. No. 5,330,781 from the year 1894 or US 2,484,408 known from 1945.

Nach der Offenbarung der DE 30 13 646 ist es ein grundsätzliches Problem bei Drehventilen, dass eine Umlenkung des Luftzuges erfolgen muss, wobei eine vierfache Umlenkung um jeweils 90 Grad erfolgen muss. Der Ansatz zur Verbesserung nach dieser Veröffentlichung ist es, dass durch eine Veränderung der Bohrungen im und des Ansatzes der Ohren am Ventil die Gesamtrichtungsänderung des Luftstroms verringert wird und so der Widerstand durch das Umfließen der Kanten verringert wird.After the revelation of DE 30 13 646 it is a fundamental problem with rotary valves that a diversion of the draft must be made, with a four-fold deflection must be made by 90 degrees. The approach to improvement according to this publication is that by changing the bores in and around the ears of the valve, the overall directional change of the airflow is reduced and thus the resistance is reduced by the flow around the edges.

Erreicht werden soll dies durch flachere nicht auf den Ventilkörpermittelpunkt gerichtete Bohrungen hin zu den Ventilrohrschleifen. Die Bohrungen für den Ein- und Ausgang des Hauptstimmzuges in das Ventil erfolgen hierbei noch klassischer Weise Richtung Mittelpunkt des Ventils, wobei hier entsprechende Ohren als Verbindungselemente zwischen Ventil -und zuführendem Rohr vorgesehen sind. Diese Ohren sind daher beim Eingang ins Ventil immer noch standardmäßig abgewinkelt und im Bereich des Übergangs in die Ventilrohrschleifen gerade ausgeführt, wodurch der geringere Umlenkaufwand entsteht.This is to be achieved by shallower not directed to the valve body center holes to the valve tube loops. The holes for the Input and output of the Hauptstimmzuges done in the valve here still classic way towards the center of the valve, in which case corresponding ears are provided as connecting elements between the valve and feeding tube. These ears are therefore still angled as standard at the entrance to the valve and straight in the area of the transition into the valve tube loops, whereby the lower deflection effort arises.

Der erfinderische Ansatz der nun vorliegenden Erfindung ist, die Ventilbauform weiter zu verbessern, wobei eine gänzlich neue Grundbauform vorgeschlagen wird. Der primäre Unterschied der Konstruktion der Drehventile ergibt sich hierbei beim Blasen des Naturtons, der in der Erfindung ohne Umlenkung durch das Drehventil durch das Instrument schwingen soll. Bei den bisherigen Drehventilen ist hier immer eine Verengung oder Umlenkung des Luftstroms auch bei nicht betätigten Ventilen gegeben, da die Ventildurchgänge schon rein bedingt durch die Herstellung Ungenauigkeiten, Stufen und Verengungen des Querschnitts aufweisen, was das Spiel und die Ansprache des Instrumentes erschwert.The inventive approach of the present invention is to further improve the valve design, wherein a completely new basic design is proposed. The primary difference in the construction of the rotary valves arises in this case when blowing the natural sound, which should oscillate in the invention without deflection through the rotary valve through the instrument. In the previous rotary valves here is always a constriction or deflection of the air flow even with non-actuated valves, since the valve passages purely due to the production inaccuracies, steps and narrowing of the cross-section, which complicates the game and the speech of the instrument.

Es ist somit bei herkömmlichen Ventilgehäusen eine Störung des Luftflusses bei unbetätigten Ventilen gegeben, wie beispielsweise bei der zuvor beschriebenen Bauform der DE 30 136 46 A1 , da der Luftstrom immer durch die Umleitung über die angesetzten Ohren in das Drehventil hinein auch bei nicht betätigten Ventil durch das erste Ventilgehäuse mit Ventilkörper hindurchgeführt und wieder in das nächste Ohr und den Übergangsrohrabschnitt zum nächsten Ventilgehäuse umgelenkt wird und so eine Umlenkung und ggf. Verengung erfährt.It is thus given in conventional valve housings a disturbance of the air flow at unconfirmed valves, such as in the previously described design of DE 30 136 46 A1 , Since the air flow is always passed through the diversion over the ears set in the rotary valve even when not actuated valve through the first valve body with valve body and is redirected to the next ear and the transition pipe section to the next valve body and so a deflection and possibly narrowing experiences.

Die Offenbarung nach der Veröffentlichung EP 0135643 weist ebenfalls diese Nachteile auf, wenngleich diese Erfindung explizit auf Verbesserungen in der Konstruktion von Drehventilen abhebt. Auch hier wird argumentiert, dass die angesprochenen Umlenkungen und Verengungen sich nachteilig auswirken, weshalb vorgeschlagen wird die Querschnittsflächen der Rohransätze, Verbindungsrohre und der Durchgänge der Ventilwechsel konstant auszuführen und alle Übergange zwischen diesen Bauelementen glatt und stufenlos auszubilden. Es ist davon auszugehen, dass auf diese Weise eine Verbesserung erreicht werden kann.The disclosure after the publication EP 0135643 also has these disadvantages, although this invention explicitly makes improvements in the design of rotary valves. Again, it is argued that the aforementioned deflections and constrictions have a detrimental effect, which is why it is proposed to make the cross-sectional areas of the pipe connections, connecting pipes and the passages of the valve change constant and smoothly and continuously form any transitions between these components. It can be assumed that an improvement can be achieved in this way.

Die Aufgabe der vorliegenden Erfindung ist es vor diesem Hintergrund, ein Ventilsystem für Metallblasinstrumente zu schaffen, dass bei offenen Ventilen einen möglichst geraden und gleichmäßigen Luftstrom durch das Ventilsystem des Instrumentes ermöglicht. Anblasen und Ansprache des Instrumentes sollen hierdurch verbessert sowie ein ausgeglichener Klang in allen Registern erreicht werden.Against this background, the object of the present invention is to provide a valve system for metal wind instruments that with open valves allows a straight and even flow of air through the valve system of the instrument. Blowing and addressing of the instrument are thereby improved and a balanced sound in all registers can be achieved.

Beim erfindungsgemäßen Ventilsystem besteht diese Problematik der Verengung und Umlenkung des Luftstroms im offenen Ventilsystem nicht, da die Luft bei nicht betätigtem Ventil gerade durch das Ventilsystem bestehend aus den hintereinander verbunden angeordneten Ventilbuchsen hindurchgeführt wird. Erreicht wird dies nach der Erfindung durch ein Ventilsystem ausgebildet als Ventilblock bzw. Ventilgehäuse, welches eine durchgängige gerade Bohrung aufweist, wobei die eingesetzten Drehventile derart ausgebildet sind, dass diese bei Nichtbetätigung lediglich eine Verlängerung bzw. ein Fortsetzung des Querschnitts der geradlinig durchgängigen Bohrung bilden.In the valve system according to the invention, this problem of constriction and deflection of the air flow in the open valve system does not exist, since the air is passed straight through the valve system consisting of the valve bushings arranged one behind the other when the valve is not actuated. This is achieved according to the invention by a valve system designed as a valve block or valve housing, which has a continuous straight bore, wherein the rotary valves used are designed such that they form only an extension or continuation of the cross section of the straight continuous bore when not operated.

Das heißt, der Ventilblock ist bei der vorliegenden Bauform aus einem Grundkörper heraus gearbeitet und nicht wie im Stand der Technik üblich eine komplizierte Verbindung einzelner Bauteile wie Ventilbuchse, angesetzte Ohren und Rohrstücke. Der Ventilblock nimmt somit den Hauptzug des Anblasrohres des Instrumentes auf und führt diesen geradlinig und mit konstantem Querschnitt als durchgängige Bohrung durch die rechtwinklig hierzu angeordneten Ventilbuchsen. Eine Verbindung der Ventilbuchsen miteinander durch Ohren und Rohrabschnitte entfällt somit. Der Ventilblock ist entsprechend mit den Bohrungen und Ventilbuchsen aus einem Stück gearbeitet.That is, the valve block is worked in the present design out of a base body and not as usual in the prior art, a complicated connection of individual components such as valve sleeve, set ears and pipe sections. The valve block thus receives the main train of the inflation pipe of the instrument and guides it straight and with a constant cross section as a continuous bore through the valve sleeves arranged at right angles thereto. A connection of the valve sleeves with each other by ears and pipe sections is thus eliminated. The valve block is accordingly worked in one piece with the bores and valve sockets.

Es ergibt sich so die vorteilhafte Möglichkeit, die Bohrungen zum Ansatz der Rohre des Blasinstrumentes komplett gerade durch die Ventilbuchsen hindurchzuführen. Ein Ansetzen von Ohren als umlenkende Verbindungskörper zwischen Ventilbuchse und Rohr ist somit überflüssig. Es ergibt sich hieraus in der Praxis insbesondere beim Anblasen eine ideale natürliche Tonerzeugung, da der Luftstrom ohne Verengung und Umlenkung durch das Instrument hindurchschwingen kann.This results in the advantageous possibility to pass the holes for the approach of the pipes of the wind instrument completely straight through the valve sleeves. An application of ears as a deflecting connecting body between the valve sleeve and pipe is therefore unnecessary. This results in practice in particular when blowing an ideal natural tone generation, since the air flow can swing through without constriction and deflection by the instrument.

Die Umlenkung in die Ventilrohrschleifen beispielsweise eines Horns erfolgt hierbei mit einer stärkeren Umlenkung als dies beispielsweise im Stand der Technik der EP 0135 643 A1 durch die Führung der angesetzten Ohren an der Ventilbuchse erfolgt, allerdings stellt dies überraschenderweise keinen Nachteil dar, sondern ermöglicht sogar eine klarere Akzentuierung und Trennung der Töne bei der Ventilbetätigung. Das heißt, die stärkere Umlenkung des Luftstroms in die Ventilrohrschleife durch das erfindungsgemäße Ventilsystem bewirkt vorteilhafterweise ein stärkeres Ansprechen dieser Töne und stellt somit sogar einen Vorteil zu herkömmlichen Konstruktionen dar. Durch die exakte Bearbeitung der Bohrungen im Ventilblock, die durch computergesteuerte Fräsmaschinen aus einem Werkstückblock erfolgen kann, ist der zylindrische Anschluß dieser Bohrungen im Übergang zu den zylindrischen Bohrungen in den Ventilzylindern deutlich genauer und so vollkommen ausgeführt, dass auch dies das stärkere und akzentuiertere Ansprechen der Töne bewirkt.The deflection into the valve tube loops, for example, a horn takes place here with a stronger deflection than, for example, in the prior art of EP 0135 643 A1 is done by the leadership of the ears attached to the valve sleeve, but this is surprisingly not a disadvantage, but even allows a clearer accentuation and separation of the sounds in the valve operation. That is, the stronger deflection of the air flow in the valve tube loop by the valve system according to the invention advantageously causes a stronger response of these sounds and thus even an advantage over conventional constructions. By the exact machining of the holes in the valve block, which are made by computer-controlled milling machines from a workpiece block can, the cylindrical connection of these holes in the transition to the cylindrical holes in the valve cylinders is much more accurate and executed so perfect that this also causes the stronger and accentuated response of the tones.

Eine vorteilhafte Ausführung der Erfindung sieht bei den Bohrungen im drehbar in der Ventilbuchse gelagerten Ventilzylinder vor, dass diese geringfügig s-förmig geschwungen ausgebildet sind, bei einer Betätigung des Ventils im Eintrittsbereich in den Ventilzylinder. Im Übergang zu den Ventilrohrschleifen bzw. im Austrittsabschnitt bei Betätigungsposition ist diese Bohrung geradlinig ausgeführt. Die Umlenkung ist zwar weiterhin nahezu rechtwinklig mit den zuvor genannten positiven Effekten, es ergeben sich hierdurch aber Verbesserungen bei der Luftführung insbesondere bei den betätigten Ventilen, da der leicht geschwungene Lauf beim Eintritt in den Ventilblock den Luftwiderstand verringert. Der Luftstrom wird weicher aufgefangen und ohne Querschnittsveränderung gleichmäßig der Ventilrohrschleife zugeführt. Zudem erfährt der Luftstrom bei dieser Bauform bei der Ventilbetätigung und -rotation um 90° eine Beschleunigung, wodurch die Töne besser im Klangzentrum getroffen werden können. Auf diese Weise kann der Spieler ein weicheres Legato erreichen.An advantageous embodiment of the invention provides for the holes in the rotatably mounted in the valve sleeve valve cylinder, that these are formed slightly curved S-shaped, upon actuation of the valve in the inlet region in the valve cylinder. In the transition to the valve tube loops or in the outlet section at the actuation position, this hole is made straight. Although the deflection is still almost at right angles with the aforementioned positive effects, this results in improvements in the air flow, in particular in the actuated valves, since the slightly curved run when entering the valve block reduces air resistance. The air flow is collected softer and supplied without cross-sectional change evenly to the valve tube loop. In addition, the air flow in this design undergoes an acceleration by 90 ° in the valve actuation and rotation, whereby the sound can be better hit in the sound center. In this way, the player can achieve a softer legato.

Ein weiteres vorteilhaftes und neues Element sind Kugellager, in denen der Ventilzylinder, der in der Ventilbuchse um 90 Grad gedreht wird, um den Luftstrom umzulenken, ober- und unterseitig geführt ist. Auf diese Weise wird erreicht, dass der Ventilzylinder in der Ventilbuchse reibungsfrei bewegt wird, das heißt, dass nicht der Ventilzylinder bei der Drehung an der Wandung der Ventilbuchse entlang schleifend gedreht wird. Dies ermöglicht sowohl eine leichtere Betätigung des Ventils als auch eine geringere Geräuschentwicklung beim Spiel. Insbesondere ist es auch eine Verbesserung in Bezug auf die Resonanz des Instrumentes, da nun keinerlei störende Resonanzen durch die Reibung des Ventilzylinders in der Ventilbuchse mehr auf den Instrumentenkörper übertragen werden. Das Instrument kann so ungestört als Resonanzkörper schwingen.Another advantageous and new element are ball bearings, in which the valve cylinder, which is rotated in the valve sleeve by 90 degrees to deflect the air flow, is guided on top and bottom. In this way, it is achieved that the valve cylinder is moved without friction in the valve sleeve, that is, that the valve cylinder is not rotated while rotating on the wall of the valve sleeve along. This allows both easier operation of the valve and a lower noise during the game. In particular, it is also an improvement in terms of the resonance of the instrument, since now no disturbing resonances due to the friction of the valve cylinder in the valve sleeve more be transferred to the instrument body. The instrument can swing as undisturbed as a resonator.

Im Folgenden soll die Erfindung anhand von Zeichnungen näher erläutert werden. Es zeigen

    geschnittenen Ventilzylindern in offenen Ventilbuchsen bei unbetätigten Ventilen;
  • Figur 2 eine Draufsicht auf das Ventilsystem mit
    geschnittenen Ventilzylindern in offenen Ventilbuchsen bei betätigten Ventilen.
In the following, the invention will be explained in more detail with reference to drawings. Show it
  • FIG. 1 a plan view of the valve system with
    cut valve cylinders in open valve sockets with unconfirmed valves;
  • FIG. 2 a plan view of the valve system with
    cut valve cylinders in open valve sockets with actuated valves.

Durch die Öffnung 1 des Ventilsystems 9 wird der Luftstrom des Anblasrohres dem Ventilsystem 9 zugeführt, wobei der Luftstrom durch Pfeile schematisch dargestellt ist. In Figur durchströmt dieser Luftstrom das Ventilsystem geradlinig und weder durch Verengungen des Querschnitts noch durch Umlenkungen behindert.Through the opening 1 of the valve system 9, the air flow of the blowing tube is fed to the valve system 9, wherein the air flow is shown schematically by arrows. In Figure, this air flow flows through the valve system in a straight line and obstructed neither by narrowing of the cross section nor by deflections.

Es wird hierbei deutlich, dass dies eine elementare Veränderung gegenüber herkömmlichen Ventilsystemen ist. Lediglich am Ausgang der Bohrung 6 im Ventilzylinder 12 ist ein geringfügiger Schwung in Form einer Verjüngung der Wandstärke der Innenwand des Ventilwechsels in diesem Bereich. Der vordere Abschnitt 7 der Bohrung 6 ist exakt übereinstimmend mit dem Querschnitt der Rohrzuführung 1 in das Ventilsystem.It becomes clear that this is a fundamental change compared to conventional valve systems. Only at the output of the bore 6 in the valve cylinder 12 is a slight momentum in the form of a taper of the wall thickness of the inner wall of the valve change in this area. The front portion 7 of the bore 6 is exactly coincident with the cross section of the pipe feed 1 in the valve system.

Grundsätzlich ist erkennbar, dass eine durchgängige Bohrung 10 konstanten Querschnitts das Ventilsystem bzw. den Ventilblock 9 durchläuft. Der Ventilblock 9 ist daher aus einem Block herausgefräst. Hierbei ist sowohl die Außenkontur, als auch die Ansätze 1 und 2 für den Hauptzug wie auch die Ansätze 3 und 4 für die Ventilrohrschleifen 11 aus dem Block gefräst, des weiteren die zylindrischen Ventilbuchsen 8 und die Bohrung 10 sowie die mit dieser rechtwinklig verbundenen Bohrungen zu den Ventilrohrschleifen 11.In principle, it can be seen that a continuous bore 10 of constant cross section passes through the valve system or the valve block 9. The valve block 9 is therefore milled out of a block. Here, both the outer contour, as well as the lugs 1 and 2 for the main train as well as the lugs 3 and 4 are milled for the valve tube loops 11 from the block, further the cylindrical valve bushings 8 and the bore 10 and the holes connected thereto at right angles the valve tube loops 11th

In Figur 2 wiederum ist dieses Ventilsystem mit betätigten Ventilzylindern 12 dargestellt. Diese sind so um 90° in der Ventilbuchse 8 gedreht. Die Pfeile verdeutlichen, dass der Luftstrom nun vom Eingang 1 in das Ventilsystem durch die Bohrung 6 im Ventilzylinder 12 rechtwinklig umgelenkt wird, wobei bei der dargestellten Ausführungsform diese Umlenkung durch den leicht geschwungenen Verlauf der Bohrung 6 im vorderen Bereich 5 weicher verläuft. Im in der gedrehten Position des Ventilzylinders 12 nun hinteren Bereich 7 zu den Ventilrohrschleifen 11 verläuft diese Bohrung 6 exakt im Querschnitt entsprechend den anschließenden Ventilrohrschleifen 11.In FIG. 2 in turn, this valve system is shown with actuated valve cylinders 12. These are rotated by 90 ° in the valve sleeve 8. The arrows illustrate that the air flow is now deflected at right angles from the inlet 1 into the valve system through the bore 6 in the valve cylinder 12, wherein in the illustrated embodiment, this deflection by the slightly curved course of the bore 6 in the front region 5 softens. In now in the rotated position of the valve cylinder 12 rear portion 7 to the valve tube loops 11 this bore 6 extends exactly in cross section corresponding to the subsequent valve tube loops 11th
