i.
Air Compressor Governor.
The air compressor governor operates with the air compressor unloading mechanism
(refer to TM 9-2815-225-34&P) to control air pressure to a maximum
(cutout) and
minimum (cut-in) pressure.
The
pressures are adjustable.
However, the difference between maximum and minimum pressures will always be about 25
psi.
Air pressure enters through one of the reservoir ports.
As pressure reaches maximum, the governor piston is
pushed up and pressure is released out one of the un-loader ports.
When minimum pressure is reached, the governor
piston goes down and pressure in the un loader lines is released out the exhaust port.
