A streamlined rotary valve includes a main body with a first, a second, and a third tube. A first casing member includes a first opening, a first and a second air inlet opening, which are in communication with a first accommodation space. The first air inlet opening is connected to an end of the first tube. A manual actuator includes a pressing section, which when pressed, an end of the third tube is set in communication with the first air inlet opening; an opposite end of the third tube in communication with the second air outlet opening; an end of the second tube in communication with the second air inlet opening; and an opposite end of the second tube in communication with the first air outlet opening, thus generates different sound effects. With 72 degrees angle of rotation and adjustable stop elements, the present invention improves speed response and accuracy. |
