Abstract (en)
An electrically controlled control valve (14) to control the air stream of a bellows (6) of an electronic accordion (1); the electrically controlled control valve (14) has: a valve body (15), in which an air passage opening (17) is obtained; a plug (19), which is mounted so as to be mobile and coupled to the passage opening (17); an electric actuator (26), which is mechanically connected to the plug (19) to move the plug (19) between a complete opening position and a closing position of the passage opening (17); a fixing body (23) with an annular shape, which is suited to be rigidly fixed to the electronic accordion (1), is arranged around the valve body (15), and is separate from and independent of the valve body (15) itself; and a flexible connecting diaphragm (24) with an annular shape which connects the valve body (15) to the fixing body (23).
