A slant plate type compressor having a capacity or displacement adjusting mechanism includes a housing for a cylinder block provided with a plurality of cylin-ders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a slant plate having a surface with an adjustable incline angle. The incline angle of the slant plate, and thus the capacity of the compressor, is controlled according to the pressure differential between the crank chamber and the suction chamber. The pressure in either the crank chamber or the suction chamber is controlled by an externally controlled valve mechanism which is disposed in a passageway linking the crank chamber and the suc-tion chamber. An internally controlled safety valve device prevents an abnormal pressure differential between the crank and suction chambers. The internally con-trolled safety valve device is provided within the externally controlled valve mecha-nism, thereby obtaining an easily manufactured slant plate type compressor having a capacity adjusting mechanism with a safety valve device.
