ABSTRACT:
A rotary vane compressor directed to increasing the gas charging efficiency is disclosed. A side block is formed with an opening which is extended such that radially outer part of its rim is located radially outwardly of the inner periphery of a cylinder. The inner periphery of the cylinder is partly removed to form a notch such that the notch is aligned with the outer part of the rim of the opening. The opening and the notch define a suction port in combination, that is, the available area of opening of the suction port is increased by the proportion of the notch. Gas is sucked into the compressor not only sidewise but also in the peripheral direction.
