Abstract
A reciprocating piston type compressor for compressing refrigerant gas for an automobile air conditioning system is improved to protect itself without protective control by a computer. The compressor detects the temperature of a part of the compressor in which the temperature increases to higher than a predetermined critical temperature when the compressor malfunctions, and changes a displacement control valve to reduce the displacement of the compressor when the detected temperature is higher than the predetermined critical temperature.
