    If the adjusting spring on the crankcase pressure regulator (CPR) is tightened,the range of refrigerant pressures that can enter the compressor will increase.

    true or false.

    The CPR valve is a close on rise of outlet pressure type of regulating valve. Increasing the spring pressure will increase the valve's controlled pressure setpoint. It will not increase the "valve's" controlled range.

    I would have to choose "false".

    On the other hand, If you read the question to mean the increase in maximum operating pressure increases the operating range of the "compressor", then I would choose "true".

    None of the above.

    True.
    The higher the spring pressure is the higher crankcase pressure has to be to close the valve.

    Hmm

    I think CPR stands for Cardio Pulmonary Resuscitation... :-)

    All pressure regulators work that way.
