<p><P>PROBLEM TO BE SOLVED: To provide a compressor unit of variable capacity capable of seceding from the minimum discharging capacity condition autonomously without needing a control by an external control device. <P>SOLUTION: A compressor unit 10 capable of controlling capacity comprises a control valve CV capable of changing discharging capacity by adjusting a pressure of crank chamber 15 in such a way that valve opening degree is adjusted by power supply; and a generator M, which is connected with a pulley 81 rotated by a drive force of engine E, generating an electric power of designated value at the designated speed of the pulley 81. The electric power generated by the generator M is supplied to the control valve CV, the control valve CV keeps the minimum discharging capacity condition without adjusting the valve opening degree when the supplied electric power is less than a designated value, the valve enlarges discharging capacity by adjusting the valve opening degree when the supplied electric power is the designated value or more, and coolant circulation is performed via an external coolant circuit 31. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
