PURPOSE: To restrain an increase in suction pressure at low delivery pressure time of a compressor. CONSTITUTION: A delivery control valve is provided with a main valve body V to supply delivery pressure Pd to a crank chamber 2 by opening the valve when suction pressure Ps is not more than preset pressure and a correcting valve body 31 to increase energizing force in the valve closing direction of the main valve body V by selectively coming into contact with the main valve body V by being energized in the valve closing direction of the main valve body V by a correcting spring 32. The correcting valve body 31 reacts to differential pressure between the suction pressure Ps or crank chamber pressure Pc and the delivery pressure Pd, and separates from the main valve body 11 when this differential pressure is not less than a prescribed value, and comes into contact with the main valve body V when the differential pressure is not more than the prescribed value, and corrects valve opening pressure of the main valve body V to the high pressure side by spring force of the correcting spring 32. |
