Abstract

The stopped pipe instrument may be simply produced by injection moulding, in which the wind is supplied through a windbox (4) past a core (3) to the resonant pipe (4) through a slot (1), to divide and produce eddying vibrations at a lip (2) which excite the air column (5). A labial valve (6) can be applied through a simple lever system to the air exit aperture (8) to stop the eddying and shut off the excitation, whilst a seal (7) prevents unnecessary loss of wind at the aperture (8).

Description

Vynález je v příkladu provedení blíže znázorněn na připojeném výkresu, kde na obr. 1 je řez shora krytou retnou píšialou s nasazeným labiovým ventilem a na obr· 2 je řez shora krytou retnou píštalou se zdviženým labiovým ventilem.DETAILED DESCRIPTION OF THE INVENTION The invention is illustrated in greater detail in the accompanying drawing, in which: Figure 1 is a cross-sectional view of a topped retina with a labyrinth mounted, and Figure 2 is a cross-sectional view of a topped retina with a raised valve.

Do shora kryté retné pišlály se vzduch zavádí vzduchovou komorou £· Vzduch potom proudí přes jádro 1 mezerou 1 a dělí se na labiu 2 za vytváření vzduchových vírů. Toto víření vzduchu způsobuje kmitání v kmitacím prostoru 1· Jestliže se nasazením labiového ventilu £, pomocí jednoduché pákové soustavy zabrání výstupu vzduchu z výstupního otvoru £, zruší se vzduchové víření potřebné pro kmitání, a tedy i pro vznik tónů· Ventilovým těsnáním Z se zabrání zbytečným ztrátám vzduchu ve výstupním otvoru £»The air is then introduced into the above-covered lip gun through the air chamber 6. The air then flows through the core 1 through the gap 1 and divides on the lab 2 to create air vortices. This swirling of the air causes oscillation in the vibration chamber 1. If the use of the labyrinth valve 5 prevents the air from the outlet opening 6 by means of a simple lever system, the air swirl required for oscillation and hence for tones is eliminated. air losses in the outlet opening £ »
