<P>PROBLEM TO BE SOLVED: To provide a control valve for a variable capacity compressor, increasing a full open flow rate so that it can be applied to a large-capacity compressor without increase in its size and weight, improving control accuracy or the like by reducing an amount of leak from a valve chamber to a suction pressure coolant introducing chamber side, and suppressing the occurrence of an operation defect such as clogging of a foreign material or locking of a valve rod. <P>SOLUTION: In the control valve for the variable capacity compressor, a lower-side valve body portion 16A and an upper-side valve body portion 16B are provided in a lower portion of a valve rod 15, and a lower-side valve seat portion 22a and an upper-side valve seat portion 22b are provided in a valve chamber 21 so that the lower-side valve body portion 16A and the upper-side valve body portion 16B contact and leave the valve seat portions, respectively. Further, a lower-side coolant outlet chamber 26A and an upper-side coolant outlet chamber 26B are provided downstream of the lower-side valve seat portion 22a and the upper-side valve seat portion 22b, respectively. <P>COPYRIGHT: (C)2009,JPO&INPIT |
