Fig.87 - Moisture-and-Oil Separator with Built-In Pressure Governor
Then, resisting the back pressure of the return valve 7 of the return valve 8, the com-
pressed air is delivered to the outlet III, and after that to the truck brake system. Simultaneously,
the compressed air, resisting the pressure of the spring 6 of the throttle governor 5 with a hole di-
ameter of 1.5 mm, is delivered through the outlet II to the regeneration reservoir. At the same
time, the compressed air flows into the cavity
Д
under the balancing piston 13, on which the
spring 11 acts. When this happens, the relief valve 14, connecting the cavity Е above the balance
piston 17 with the environment via the channel Ж and cavity З , is open. The inlet valve 24 under
action of the pusher 25 and spring 12, is closed. Under the action of the spring 19, the decompres-
sion pressure control valve 18 is also closed. This condition of the moisture-and-oil separator with
built-in pressure governor corresponds to the brake system receivers filling with compressed air
from the compressor.
