A rotary compressor includes a stator (2) having an inlet (3) and an outlet (4) for gas to be compressed, a rotor (5) within the stator (2) and vanes (7) being present to define cells (C) to transport gas from the inlet (3) to the outlet (4). According to the invention a supplementary passage (11) is present in the end wall (10) to direct gas from a region of high pressure (A) towards a region of lower pressure (B) thereby allowing lubricant to reach the region of high pressure gas.
