A. Steam leaking into the chamber under the governor piston will form a
pressure and prevent the piston being forced downward to close the steam
valve; the compressor will therefore continue to work until the main
reservoir pressure is about equal to boiler pressure.
31. Q. If the pipe leading from the feed valve pipe to the excess
pressure head of the governor breaks, what effect will it have on the
compressor?
A. The compressor will stop when the main reservoir pressure reaches
about forty-five pounds.
