SECTION 9
SERVICING OF MISCELLANEOUS DEVICES
This section will cover basic maintenance of various control devices used with the compressor
module. Refer to Fig 9-1, Page 70, for pictorials of referenced hardware.
INLET CONTROL VALVE ASSEMBLY
Inlet-Valve Assembly (2) -
This device is located within and below the intake flange of the compressor -
see Fig. 9-1 for internal details. During the loaded state, the
inlet poppet (2.2)
remains open and
enables atmospheric air to enter the compressor inlet - this is done by venting to atmosphere the gas
trapped underside of the piston via
check valve (19)
and
orifice
(18)
. During the unloaded state, a two-
way solenoid valve feeds pressurized air underneath the
piston
(2.1)
, forcing it and
the inlet poppet
(2.2)
upward and blocking-off the compressor intake. A small purge check valve, located in the poppet,
allows a stream of air to reach (e.g., purge) the rotors and keep them from unstable, noisy operation and
producing sufficient pressure to maintain cooling / lubricating oil flow.
FIGURE 9- 1 – Inlet Valve Assembly
Air/oil pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
and filters.
