<p>The invention relates to a wind instrument comprising a basic body in which extends a central duct bounded by a peripheral wall of the basic body, a plurality of openings in the peripheral wall which connect the duct with the surrounding air, a number of valves mounted on the basic body and each comprising a closure member (5) coacting with an opening and comprising control means (49,52) connected to said valves, wherein said control means guide said closure member for movement between a closed position in which the opening is closed by said closure member and an open position in which the opening is left clear, wherein the closure member comprises a plate (16) of substantially stiff material which is provided on the side facing toward the opening with sealing material (18) and in the closed position engages round the opening and that the closure member is connected to the control means by yieldable means (52) and wherein the plate of substantially stiff material is connected to a rod (54) of said control means by means of an engagement element (49) fixedly mounted on the rod or forming part of said rod. Said engagement element extends from the centre of the plate in diverse directions over only a fraction of the radius of the plate. <IMAGE></p> |
