74. Q. If an intermediate discharge valve breaks, what may be done?

A. Remove the broken valve, blocking the opening made by its removal,

and as there are two upper and two lower intermediate discharge valves

the air will now pass from the low pressure cylinder to the high

pressure cylinder through the other valve.

75. Q. If a final discharge valve breaks, what effect will it have on

the compressor?

A. Will cause the compressor to stop when the main reservoir pressure is

in excess of forty pounds.
