Abstract
Provided is a screw compressor, accommodating a pair of rotatable male and female screw rotors in a compression chamber formed in a casing, wherein the casing includes: an internal dividing wall that defines an inside interior space; and an outer wall that defines an outside interior space arranged outside the inside interior space The screw compressor further includes: a communication pipe member that penetrates the outer wall and extends across the outside interior space, and an end of the communication pipe member being inserted into the internal dividing wall so that the inside interior space communicates with a passage outside the outer wall. By using this communication pipe member, fluid can pass across an interior space in the casing to be fed to another interior space formed further inside.
