The disadvantage of rotary type compressors for automotive air-conditioners is that the refrigerating capacity increases linearly in proportion to the increase in engine speed, and so in the present research, attention was focused upon the phenomenon of the refrigerating flow in the suction stroke, and the conditions for construction of capacity self-controllable type compressors by selecting suitable parameters were established, In this report, the basic equations which represent all stages of the vane's position in suction passage during the suction stroke are introduced. By theoretical analysis of the equations, it is found that the capacity self-control characteristics by choosing the area of the suction port and suction groove can be calculated. These results are confirmed by the experiments.
