2.1.5.4. Executive mechanism of system (VAD) (L3)

Fig. 2.58. Executive mechanism of VAD system: 1–the zaslonka is open; 2–the zaslonka is closed; 3–executive mechanism of a zaslonka of VAD system; 4–core; 5–VAD system zaslonka; 6–vacuum of an inlet collector


Opens and closes zaslonka. Usually, the core under the influence of a spring opens a zaslonka. When the vacuum from an inlet collector moves to a diaphragm compartment, the core is involved, closing a zaslonka. The executive mechanism of a zaslonka consists of a core, a diaphragm and spring compartment (fig. 2.58).
