Abstract

This invention relates to a flow path selector valve for use in wind instruments made of metal, such as a trumpet or a French horn. The valve comprises at least one pair of valve members, which consist each of a solid of revolution and are rotatably mounted on opposite sides of and in sliding and sealing contact with a centrally disposed, hollow bearing and drive block and integrally connected by a shaft. Each of said valve members consists of a cylinder, preferably of a cone, and contains a curved pipe section, which defines a flow path from an axial opening formed in the axially outer end portion of the valve member to a lateral opening formed in the shell of the valve member. The curved pipe sections are arranged in mirror symmetry in the valve members of said pair. Two air ducts are provided on opposite sides of the pair of valve members and devine flow paths differing in length. Each of said air ducts has two openings at opposite ends. The valve members are adapted to rotate in unison, preferably through 180 DEG , between a first position in which the lateral openings of both valve members register with the two openings of one of said air ducts and a second position, in which the lateral openings of both valve members register with the openings of the other air duct. The two open ends of each of said air ducts are defined in part by the centrally disposed bearing and drive block.

Description

Die Erfindung betrifft einen Metallblasinstrumentenventilkörper, bestehend aus einem über eine Drehachse verbundenem Luftsteuer-Ventilpaar, verwendbar für Trompete, Horn od. dgl.The invention relates to a metal wind instrument valve body, consisting of an air control valve pair connected via an axis of rotation, usable for trumpet, horn or the like.

Es sind einerseits sogen. Perinet-Ventile und andererseits Drehventile als Luftsteuerventile für Metallblasinstrumente bekannt.On the one hand there are so-called Perinet valves and on the other hand rotary valves are known as air control valves for metal wind instruments.

Das Perinet-Ventil besteht aus einem gegen Federwirkung in einem Zylinder längsverschieblichen Kolben mit Längs-und Querlochungen, wodurch eine Luftsteuerung über eine kürzere oder längere Umleitung zur Erzeugung unterschiedlicher Töne erfolgt. Hierbei sind zwar die vorgesehenen runden Durchgangsquerschnitte für ungehinderten Luftdurchgang günstig für Lautstärke und Klangqualität, aber dem stehen ein langer Betätigungsweg und große Massenträgheit einem schnellen Spielen gegenüber.The Perinet valve consists of a piston which is longitudinally displaceable against spring action in a cylinder with longitudinal and transverse perforations, as a result of which air control takes place via a shorter or longer diversion to produce different tones. Although the round passage cross sections provided for unimpeded air passage are favorable for volume and sound quality, this is offset by a long actuation path and great inertia and fast play.

Das Drehventil besteht aus einer Ventilscheibe mit umfangsseitigen Luftein- und -auslässen, welche durch radiale oder sektorale Kanäle verbunden sind. Diese Anordnung ermöglicht zwar ein schnelles Spielen, infolge kurzem Betätigungsweg aber die Luftdurchgänge weisen große Richtungsänderungen in der Luftführung mit scharfen Kanten und Verengungen auf, welche Lautstärke und Klangqualität sowie die Ansprechbarkeit der Töne beeinträchtigen.The rotary valve consists of a valve disc with peripheral air inlets and outlets, which are connected by radial or sectoral channels. Although this arrangement enables fast playing, due to the short actuation distance, the air passages have large changes in direction in the air duct with sharp edges and constrictions, which impair the volume and sound quality as well as the responsiveness of the tones.

Auch sind nach der DE-B-29 18 247 Drehventile für Metallinstrumente, bekannt, bestehend aus einem über eine Drehachse verbundenen Luftsteuer-Ventilpaar in Form von Drehkörpern mit Rohrknie bei stimseitigem Luftein- bzw. -austritt und umfangseitiger Aus- bzw. Einleitung zur Luftumleitung, wobei durch Drehung die jeweils gewünschte Luftführung einstellbar ist. Hierbei handelt es sich um eine spezielle Ausführung, insbes. für ein Tripelhom mit einer Mehrzahl von zu steuernden Stimmzügen.Also known from DE-B-29 18 247 are rotary valves for metal instruments, consisting of an air control valve pair connected via an axis of rotation in the form of rotating bodies with a tubular elbow with front-side air inlet and outlet and circumferential outlet and inlet for air diversion , whereby the desired air flow can be adjusted by rotation. This is a special version, in particular for a triple home with a plurality of tuning trains to be controlled.

Schließlich ist nach der FR-A-2 305 664 ein Ventilkörper ähnlicher Bauart für Rohrleitungen in Installationssystemen bekannt, dessen Anpassung zur Verwendung für die Konstruktion von Musikinstrumenten jedoch nicht naheliegend ist.Finally, according to FR-A-2 305 664, a valve body of a similar design is known for pipes in installation systems, the adaptation of which, however, is not obvious for use in the construction of musical instruments.

Demgegenüber ist es Aufgabe der Erfindung allgemein für Blasinstrumente einen kompakten Ventilkörper zu bauen in leichter Ausführung mit durchgehend rundem Luftdurchgang, um das Instrument bei leichter Ansprechbarkeit der Töne sowie großer Klangqualität und Lautstärke mit einer vorteilhaften Mechanik schnell spielen zu können.In contrast, it is an object of the invention in general for wind instruments to build a compact valve body in a light design with a continuous round air passage in order to be able to play the instrument quickly with an advantageous mechanism, with easy responsiveness of the tones as well as great sound quality and volume.

Diese Aufgabe wird gemäß der Erfindung durch einen Metallblasinstrumentenventilkörper nach dem Oberbegriff des Anspruchs 1 dadurch gelöst, daß die Drehkörper in Zylinderform beidseits an einem hohlen Mittellager-und Antriebsblock mit durchgehender Lagerwelle anliegen und jeweils einen Rohrkrümmer aufnehmen, bei vollem Axialein- bzw. -auslaß, welche Rohrkrümmer in der einen Drehstellung umfangseitig zu einem kürzeren und in der anderen Drehstellung umfangseitig zu einem längeren Luftweg zur Luftumleitung führen und beide Luftwege mit ihrem Ein- -bzw. Ausgang unmittelbar am Mittellager- und Antriebsblock angeordnet sind. Hierbei beträgt der Umleitungswinkel von jedem Rohrkrümmer weniger als 90° und deren umfangsseitiger Aus- bzw. Einlauf in den jeweiligen Luftweg ist als schräger und gerundeter Übergang ausgebildet, wobei der Gesamtdurchgang konstant oder konisch erweitert ist.This object is achieved according to the invention by a metal wind instrument valve body according to the preamble of claim 1 in that the rotating bodies in cylindrical form abut on both sides of a hollow central bearing and drive block with a continuous bearing shaft and each receive a pipe bend, with a full axial inlet or outlet, which pipe elbows lead to a shorter circumferential direction in the one rotational position and a longer one in the other rotational position to the circumference, and both airways with their inlet or outlet. Output are arranged directly on the central bearing and drive block. Here, the diversion angle of each elbow is less than 90 ° and its circumferential outlet or inlet into the respective airway is designed as an oblique and rounded transition, the overall passage being constant or flared.

Die schwenkbare, umfangseitige Dichtfläche jedes Rohrkrümmers ist hierbei im Zylinderkörper mit großer Stirnfläche nach außen durch eine Rohrkrümmerlinie begrenzt. Die jeweils einen Rohrkrümmer aufnehmenden Zylinderkörper sind bis auf den Lagerrand hohl ausgebildet und insbes. dünnwandig aus Kunststoff gefertigt. Dies führt zu einem besonders geringen Drehmoment, was beim Spiel aufzubringen ist.The pivotable, circumferential sealing surface of each pipe bend is limited in the cylinder body with a large end face to the outside by a pipe bend line. The cylinder bodies, each of which receives a pipe elbow, are hollow except for the bearing edge and, in particular, are made of thin-walled plastic. This leads to a particularly low torque, which has to be applied when playing.

Nach einer besonderen Ausbildung liegt der kürzere Luftweg als Rohrbogen zur Luftumleitung unmittelbar dem Mittellager- und Antriebsblock an, während für den längeren Luftweg beidseits des Mittellager- und Antriebsblocks je ein Anschlußstutzen vorgesehen ist.According to a special training, the shorter air path as a pipe bend for air redirection lies directly on the central bearing and drive block, while a connection piece is provided for the longer air path on both sides of the central bearing and drive block.

Auch können die verschiedenen langen Luftwege über jeweils beidseits des Mittellager- und Antriebsblocks vorgesehene Stutzen angeschlossen sein. Durch die vorgeschilderte Ventil-Ausbildung lassen sich große runde Luftdurchgänge mit weichen, fliessenden Kurven erreichen bei leichten Ventilen - wenig Masse - und angepaßten Antriebsteilen, wobei in der Regel ein Ventilblock aus drei Ventilpaaren in Reihe gebildet wird und für Doppel- oder Dreifachblasinstrumente zwei bzw. drei solcher Ventilreihen nebeneinander liegend angeordnet werden.The various long airways can also be connected via connectors provided on both sides of the central bearing and drive block. Thanks to the valve design described above, large round air passages with soft, flowing curves can be achieved with light valves - little mass - and adapted drive parts, whereby a valve block is usually formed from three pairs of valves in series and two or three wind instruments for two or three such valve rows can be arranged side by side.

Hierbei können die Drehkörper als Zylinder-oder Kegelkörper die Rohrkrümmer für den Luftdurchgang als Hohlform, umgeben, wodurch das Ventilpaar bei spiegelsymmetrischem Aufbau nur Minimalgewicht erhält. Anstelle einer um 180° verschwenkten Drehstellung könne die Ventile auch in anderem Winkel zueinander verdreht sein.In this case, the rotating bodies as cylinder or cone bodies can surround the pipe bends for the air passage as a hollow shape, as a result of which the pair of valves is given only minimal weight with a mirror-symmetrical construction. Instead of a rotational position pivoted through 180 °, the valves could also be rotated at a different angle to one another.

Wie aus der Schnittdarstellung in Fig. 1 ersichtlich wird, besteht ein Ventilpaar aus zwei sich nach außen erweiternden Kegelkörpem 1 und 2 mit mittiger Lagerwelle 3, 4 zur Aufnahme im Mittellager- und Antriebsblock 5. Hierbei besitzen die Kegelkörper 1, 2 auf ihrer Stimfläche runde Luftein- und -austrittsöffnungen 6, 7, welche jeweils über Rohrkrümmer 8, 9 die Aus- und Einleitungen 10, 11 für den Rohrbogen 12 als kürzeren Luftweg bzw. die Rohrstutzen 13, 14 um 180° gedrehter Stellung an einem längeren Luftweg anschließen. Die Luftein- und -austritte 6, 7 nehmen als runde Öffnungen jeweils praktisch die ganze Stimfläche der Kegelkörper 1,2 ein, woran sich die Rohrkrümmer 8, 9 mit der Aus- und Einleitung 10, 11 gleichen Durchmessers am Kegelmantel anschließen. Hierbei umgeben die Kegelkörper 1, 2 die Rohrkrümmer 8, 9 jeweils als Hohlform, so daß sich für das Ventilpaar nur ein Minimalgewicht ergibtAs can be seen from the sectional view in Fig. 1, a pair of valves consists of two outwardly expanding cone bodies 1 and 2 with a central bearing shaft 3, 4 for receiving in the central bearing and drive block 5. Here, the cone bodies 1, 2 have round on their end face Air inlet and outlet openings 6, 7, each of which connects the outlets and outlets 10, 11 for the pipe bend 12 as a shorter air path or the pipe sockets 13, 14 to a longer air path, rotated through 180 °, via pipe elbows 8, 9. The air inlets and outlets 6, 7 each take up practically the entire end face of the cone body 1, 2 as round openings, which is followed by the pipe elbows 8, 9 with the outlet and inlet 10, 11 of the same diameter on the cone jacket. Here, the cone body 1, 2 surround the elbows 8, 9 each as a hollow shape, so that there is only a minimum weight for the pair of valves

Der Umleitungswinkel von jedem Rohrkrümmer beträgt weniger als 90°, wobei deren umfangsseitiger Aus- bzw. Einlauf 10a, 11 a in den jeweiligen Luftweg als schräger und gerundeter Übergang ausgebildet ist. Der Gesamtdurchgang ist hierbei, wie gezeichnet, konstant oder kann auch von der Eintrittsöffnung 6 zur Austrittsöffnung 7 leicht konisch ausgebildet sein. Die schwenkbaren, umfangsseitigen Dichtflächen 8a, 9a jedes Rohrkrümmers 8, 9 im jeweiligen Kegelkörper 1, 2 mit großer Stirnfläche nach außen sind, wie ersichtlich, durch eine Rohrkrümmerlinie begrenzt.The diversion angle of each pipe elbow is less than 90 °, the peripheral outlet or inlet 10a, 11a of which is designed as an oblique and rounded transition into the respective airway. The overall passage is, as shown, constant or can also be slightly conical from the inlet opening 6 to the outlet opening 7. As can be seen, the pivotable, circumferential sealing surfaces 8a, 9a of each pipe bend 8, 9 in the respective cone body 1, 2 with a large end face are limited by a pipe bend line.

Anstelle der Verschraubung kann bei einfacher Ausführung auch eine Verklebung der Teile erfolgen.To form the bearing shaft, the conical bodies 1 and 2 have the axle pin 3 on the one hand and the hollow axle 4 on the other hand, the latter then being fitted with a drive ring 15. Here, the smaller end faces of the tapered bodies 1, 2 rest against the central bearing and drive block 5 under seal 5a. The one-sided axle pin 3 is held in the other side hollow axis 4 by means of an axial screw 16, which is supported by means of a clamping ring 17 in the hollow shaft 4, access is achieved through the plug 17a. Instead of the screw connection, the parts can also be glued in a simple design.

Die Drehung der Kegelkörper 3 und 4 erfolgt über einen Druckhebel 18 entsprechend Fig. 7, welcher unter Wirkung der Gelenkfeder 19 in Ruhestellung gehalten ist und der eine angelenkte Schubstange 20 mit um den Antriebsring 15 der Lagerwelle 3, 4 geführter Antriebsschnur bzw. - Doppelschnur 21 betätigt. Der Druckhebel 18 ist an seinem Betätigungsende 22 abgewinkelt und durch eine Schlitzhülse 23 mit Dämpfungsanschlägen 24 hinter der angelenkten Schubstange 20 wegbegrenzt geführt.
