<p><P>PROBLEM TO BE SOLVED: To provide a capacity control valve capable of more accurately controlling a discharge capacity of a variable displacement compressor. <P>SOLUTION: In the capacity control valve, a valve seat VS and a valve element VB are provided in passages 4f, 4e, 4b, 4d connecting a discharge chamber 5b and a crank chamber 9 of the variable displacement compressor, and a pressure of the crank chamber 9 can be changed by changing openings of the passages 4f, 4e, 4b, 4d between the valve seat VS and the valve element VB by PWM control. A damping member 22 used as a damper for suppressing repulsion between the valve seat VS and the valve element VB generated by collision of the valve seat VS and the valve element VB when the openings of the passages 4f, 4e, 4b, 4d are small is included between the valve seat VS and the valve element VB. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
