CONSTITUTION:Amount of gas used at terminals is now reduced so that pressure inside an oil separator 9 is increased. The pressure is then detected by a pressure sensor 40. Responding to the signal from the pressure sensor 40, an indicating electromagnetic pulse signal is sent to a stepping motor 35 via a controlling means, not illustrated, such as a controlling circuit board, for example, of a micro-computer. Revolutional angle of the output shaft 34 of the stepping motor 35 is then varied. The relative positions of both a vlave part passage 32 and a valve body 33 inside an intake throttle valve 30 are thereby changed to reduce the opened degree of the valve or close the valve. A compressor 7 will then start capacity control operation or no-load operation. When amount of gas used at terminals gets great, the motor 35 is driven reversely to open the valve 30. The compressor will then be operated under full load. The compressor, which is built up simply as described above, can be provided with higher capacity controlling characteristics and higher reliability.
