An A/C compressor pressure relief valve is incorporated in the compressor A/C manifold and tube to:
^
relieve unusually high refrigerant system discharge pressure buildups of (3,792 kPa [550 psi] and above).
^
prevent damage to the A/C compressor and other system components.
^
avoid total refrigerant loss by closing after the excessive pressure has been relieved.
