A. Lower receiving or upper discharge valve broken or stuck open.
71. Q. If a receiving valve breaks or sticks open, how may it be located?
A. The air will flow back to the atmosphere as the piston moves toward the defective valve and may be detected by holding the hand over the strainer.
72. Q. If a receiving valve in a cross-compound compressor 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 receiving valves the compressor will now take air through the other valve.
73. Q. If an intermediate discharge valve breaks or sticks open, how may it be located?
A. No air will be taken in to that end of the compressor as the piston moves from the defective valve, and may be located by holding the hand over the strainer.
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?
