Abstract
This disclosure relates generally to economized screw compressors. Particularly, this synchronized economizer ports on both the female and the male rotor sides of a compressor housing. The economizer ports simultaneously provide gas to a compression chamber formed by male and female rotors. The synchronized male side and female side economizer ports are configured to open and close at opening and closing angles, respectively. The opening angles and the closing angles each differ by at most half of an angular width of a male lobe of the compressor.
