Abstract
In a single screw compressor, gates of a gate rotor mesh with helical grooves of the screw rotor in a casing. The casing has a low pressure space, and a divider wall covering the outer peripheral surface of the screw rotor to divide the fluid chamber formed by the helical groove from the low pressure space. An inlet is formed in the divider wall to partially expose the outer peripheral surface of the screw rotor to the low pressure space. The fluid chamber in a suction phase into which the low pressure fluid flows from the low pressure space is divided from the low pressure space by the gate entering the helical groove after the helical groove has moved from a position where the helical groove faces the inlet to a position where the helical groove is covered with the divider wall.
