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

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


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