<p>PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement compressor including a body part of such a structure that a solenoid and a connector part are formed in a single piece through a molding process, wherein the waterproofing structure is simplified by forming a cavity internally and the valve characteristics are stabilized by furnishing an air passage for putting the cavity in communication to the outside air so that the rise in the internal pressure of the cavity due to heat emission is precluded. SOLUTION: The control valve of variable displacement compressor is equipped with a control valve part 1 to control the displacement of the variable displacement compressor, a valve drive part 2 to drive the control valve part, and a connector part 3 wherewith a power supply for driving of the valve drive part is connected, wherein the connector part 3 and the solenoid 20 to constitute the valve drive part are formed in a single piece through molding process so that the body part 30 is formed, and inside the body part 30, the cavity 29 to components is formed simultaneously with the body part. The body part 30 includes air passage 40 to put the cavity 29 in communication with a recess 35 provided at the end of the connector part.</p> |
