<p>A rotary compressor of the sliding vane type in which the refrigerating capacity at high speed operation of the compressor is restrained by making use of the drop of the refrigerant pressure in the vane chamber down to a level below the pressure of the refrigerant supply source in the suction stroke of the compressor. The compressor has a rotor, vanes slidably carried by the rotor, a cylinder accommodating the rotor and the vane, plates fixed to the cylinder and closing opposite open ends of vane chambers defined by the rotor, the vanes and the cylinder, and a suction port and a discharge port which provide passages between the vane chambers and the outside of the compressor. A spacer for adjustment of the refrigerating capacity is disposed in the suction port. When the compressor is used in an automobile air conditioner, it is possible to obtain a desired refrigerating capacity controlling characteristics of the compressor matching the characteristics of the engine and automobile, simply by selection of the spacer without substantially changing other parts of the compressor.</p> |
