<P>PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement compressor, effectively inhibiting wear, erosion and the like of the inner peripheral edge of a valve port. <P>SOLUTION: The control valve for the variable displacement compressor includes: a valve stem 15 having a valve element part 15a; and a valve body 20 having a guide hole 19 in which the valve rod 15 is inserted fittingly and slidably, and a valve chamber 21 provided with the valve port 22 which the valve element part 15a contacts to and separates from, and provided with a discharge pressure refrigerant lead-in opening 25 on an upstream side of the valve port 22 and a refrigerant lead-out opening (24, 26) on a downstream side of the valve port 22 in communication with the crank chamber of the compressor. For preventing a refrigerant from being split when leaving the valve port 22, the refrigerant lead-out opening is composed of a single lead-out chamber 24 provided immediately downstream of the valve port 22 and a plurality of communication holes 26 proving communication between the lead-out chamber 24 and the outside of the valve. <P>COPYRIGHT: (C)2012,JPO&INPIT |
