Abstract

1378539 Rotary positive-displacement machines AERZENER MASCHINENFABRIK GmbH 20 April 1972 [21 April 1971] 18498/72 Heading F1F In a meshing-screw compressor, or motor, the male rotor HL I of the first stage is coupled directly to the female rotor NL II of the second stage and is driven through a reduction-gear unit T, the total number of teeth on the rotors of the first stage being less than that of the teeth of the rotors of the second stage e.g. 3 and 4, and 4 and 6, respectively.
