<P>PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement compressor hardly receiving adverse effect to control from the ejection pressure Pd without complicating the configuration, and a manufacturing process thereof. <P>SOLUTION: The control valve comprises a valve rod 15 having a shaft part 15c, a middle byway small diameter part 15b with a diameter smaller than that of the shaft part 15c and a valve body part 15a with a diameter larger than that of the shaft part 15c, and a valve main body 20 having a valve chamber 1 provided with a guide hole 19 for slidably inserting the shaft part 15c of the valve rod 15 and a valve port 22 to be contacted with and separated from the valve body part 15a. The valve port 22 is set at an aperture Da capable of being inserted with the shaft part 15b before assembly of the valve. After assembly of the valve (after inserting the shaft part 15c into the guide hole 19 via the valve port 22), the effective aperture area of the valve port 22 is reduced by reducing the diameter of the valve sheet part 22a by hitting the outer periphery of the valve sheet part 22a from below with a punch, and the like. <P>COPYRIGHT: (C)2009,JPO&INPIT |
