Abstract

A capacity control device for variable-capacity compressors is provided with a high-pressure valve portion 36 for opening or closing the communication between the discharge chamber 21 and the crank case 12; a low-pressure vale portion 41 for opening or closing the communication between the suction chamber 20 and the crank case 12; a valve open-close member 35 for opening or closing so as to reverse the open-close relationship between the high-pressure valve portion 36 and the low-pressure valve portion 41 by advancing or retreating; a pressurising chamber 53 for applying pressure to the valve open-close member 35 in a direction that opens the high-pressure valve portion 36 by means of a wider effective pressure-receiving area than that of the high-pressure valve portion 36. The device is driven with only small actuation forces by an electromagnetic solenoid 50 to open or close a communicating path between the discharge chamber 21 and the said pressurising chamber 53. <IMAGE>
