2. Pneumatic lines (2) connected to a switch (1) quick connectors or, according to 10.93, a shrink fit. Shut-off valve integrated in the circuit breaker (1), closes the vacuum tubes according to the position of the regulator. Switch (1) is supplied with vacuum from the inlet pipeline through the distribution vacuum block.
3. Switch (1) has several provisions: «0», «1», «2» And «3». Different positions of the regulator apply different depths of vacuum to hold the reflector in the desired position.
The dependence of the depth of rarefaction on the position of the regulator
Regulator position | Adjusting position of the adjusting element, mm | Dilution depth, bar |
0 | 0.0 | 400 ± 30 |
1 | 0.95 | 290 ± 30 |
2 | 1.70 | 200 ± 30 |
3 | 3.00 | 50 ± 30 |
