2.1.5.5. Electromagnetic valve of system (VAD) (L3)

Fig. 2.59. Electromagnetic valve of VAD system: 1–a food is included; 2–a food is switched off; 3–the channel A (to the atmosphere); 4–the channel B (on the executive mechanism); 5–the channel C (to an inlet collector); 6–spiral; 7–plunzher; 8–spring


The electromagnetic valve switches the channel of vacuum of an inlet collector between an inlet collector and the executive mechanism. When a food is included, the plunzher of the valve is delayed and opens pass between air channels A and B which opens access to atmospheric air to the executive mechanism of a zaslonka. When a food is switched off, the plunzher comes back forward and opens pass between air channels B and C which opens access to vacuum from an inlet collector to the executive mechanism of a zaslonka. The electromagnetic valve consists of the solenoid, a spring, a plunzher and the filter (fig. 2.59).
