Definitions

  • the invention relates to a valve system for brass instruments according to the preamble of patent claim 1.
  • 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.
  • valves 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • valve cylinder which is rotated in the valve sleeve by 90 degrees to deflect the air flow, is guided on top and bottom.
  • 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.
  • 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.
  • valve block 9 is therefore milled out of a block.
  • 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
  • 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.
  • this bore 6 extends exactly in cross section corresponding to the subsequent valve tube loops 11th
