In the operation of the helical-rotary compressor, refrigerant vapor enters the
compressor housing through the intake port. The intake port in this example
is at the top of the compressor housing.
The entering refrigerant vapor is at a low, suction pressure and fills the grooves
or pockets formed by the lobes of the rotors. As the rotors turn, they push the
pockets of refrigerant toward the discharge end of the compressor.
