AbstractThe invention relates to a rotary screw compressor with liquid-injection means. The axes of the rotors (18, 20) are in a horizontal plane and the inlet channel (26) reaches the compressor from below. According to the invention there are provided means for preventing that liquid leaking out from the working space of the compressor through the inlet port (46) reaches the inlet channel (26). These means include partition walls (34, 36) mounted in an inlet chamber (28) connecting the inlet channel (26) to the inlet port (46).
