This paper is concerned with a sliding vane type rotary compressor for an automotive air conditioner. The load when the compressor starts depends on the presence of liquid refrigerant. The fundamental characteristics of the liquid compression at the starting were examined experimentally. The pressures in a cylinder and the torque of the shaft of a compressor were measured by changing the speed of the compressor and the amount of liquid refrigerant stored in the reservoir between the evaporator and the compressor. Liquid compression occurred frequently as both the compressor speed and the amount of liquid refrigerant increased. The period of liquid compression was almost in proportion to the amount of liquid refrigerant, not depending on the compressor speed. As the compressor speed increased, the value of the pressure peak increased noticeably, but the value of the torque peak didn't increase so much.
