Definitions

  • valve passages in conventional valves have production-related steps and edges and changes in cross-section as well as disturbing pipe joints between the valves of a set, which disrupt the response of the instrument and require a higher physical effort on the part of the fan.
  • Brass, nickel silver or bronze is used for the valve sleeves and brass or phosphor bronze for valve changes. This leads to material removal due to corrosion or limescale removal using acids, which significantly shortens the service life and reduces the tightness of the valves. This applies to both the valve sleeve and the valve change, with the latter also adding the relatively high mass.
  • valves of a set are individually fitted and then connected to form a set, which leads to problems both in production and in the positioning of the stop wings.
  • FIG. 1 two interconnected known valves, each with two pipe lugs 1, 2, and 3, 4, the valve sleeve 5, the valve change 6 and the connecting pipes 7.
  • FIGS. 1 and 3 it can be seen that the cross-section of the passage in the valve change, which is predetermined by the scale, that is to say by the inner diameter of the pipe lugs 1 or 2, and that transition stages are present. This is particularly evident at 8, where the pipe lugs and connecting pipes pass into the passage of the valve change.
  • these levels and the cross-sectional changes worsen both the response and the mood of the instrument, whereby In addition, there is a large spread in production, so that the conditions can be even worse, especially due to the creation of additional stages.
  • FIG. 3 it can be seen from FIG. 3 that the passages are strongly opened, which results in a considerable change in cross-section and thus protruding edges 8a.
  • FIG. 2 A valve according to the invention is shown in FIG. 2 and the four pipe lugs 11, 12, 13 and 14, the valve housing 15, the valve change 16 and the connecting pipes 17 can be seen.
  • the scale and the passage when changing the valve is constant except for a small deviation of about 1 to 3%, which means that the cross-sectional area from the pipe attachment or connecting pipe through the valve change to the next pipe attachment or Connection tube practically does not change.
  • the fact that the passage is not completely closed, see FIG. 4 at 30, is intended to enable a tone binding when the valve is switched over.
  • the new geometric shape, in particular of the valve change can be achieved by using contemporary production processes, as are common in other industrial technology, for example in machine tool construction, for example by means of tenon and ball milling cutters.
  • the pipe attachments and the connecting pipes are conventional, standardized for each instrument, but specially curved pipes made of brass or stainless steel, although it should also be noted is that the connecting tubes here are in one piece, in contrast to the previously known ones according to FIG. 1, which have to be soldered to one another via clamps or clips.
  • valve sleeves are made of brass, nickel silver or bronze and the valve changes are made of brass or phosphor bronze.
  • the valve sleeve is preferably made of stainless steel, which can be chrome-plated or nickel-plated on the outside. This eliminates the corrosion that occurs with conventional valve sleeves and the resulting material removal, in particular when removing limescale using acids, which results in a considerably longer service life with unchanged tightness with respect to the valve sleeve.
  • the valve change can, for example, be made of hard-chromed aluminum, which results in a considerable reduction in mass and here, too, there is no corrosion or material removal when removing limescale with acids. This also results in an extended service life with unchanged tightness for valve replacement, a lighter instrument and a shorter reaction time when actuating the valve.
  • hard chrome-plated brass gives the same advantages as the valve sleeve, that means no material erosion due to corrosion and an extended service life with unchanged tightness.
  • titanium which gives the same advantages as hard-chromed aluminum, i.e. mass reduction, no corrosion, which results in a lighter instrument and a shorter response time when actuating the valve.
  • valve sleeves When manufacturing a valve set, the valve sleeves are first turned to honing dimensions, the pipe extensions are soldered on, and then the inside of the sleeves is honed and rolled.
  • the valve changes are first turned to grinding dimensions, milled and then tip ground to size and if necessary galvanically treated and can then be inserted into any sleeve without fitting.
  • a notch 24 is provided on the valve sleeve, at the bottom in FIG. 6, and four notches 26 are offset by 90 ° on the bearing cover 25, these notches being aligned with respect to both bores 27 for fastening the stop bracket.
  • the valve change axis 29 is designed as a square on the drive side and has a directional notch 28 which defines the passages and serves to position the stop wing, which can be inserted in all four positions as a result of this measure. This measure results in universal use of the valve with regard to the position of the valve drive, because the position of both the valve change and the bearing cover, or the stop bracket and the stops, can be set exactly at any time in the four possible positions. These measures ensure a more rational production of the musical instrument and easier storage with fewer individual parts.
