PROBLEM TO BE SOLVED: To suppress noise due to fine oscillation of a plunger, in a control valve for a variable displacement compressor subjected to electrification control of a PWM(Pulse Width Modulation) system.SOLUTION: A solenoid 3 includes: a core 42 that is fixed to a body 5; a sleeve 44 that is fixed to the core 42 so as to seal the end part of the core 42 and form an internal space 45 cut off from atmosphere, and into which refrigerant is introduced by communicating the internal space 45 with the inside of the body 5; and a plunger 46 that is stored in the internal space 45 and arranged oppositely to the core in an axial direction, and can be displaced integrally with a valve body 33 in the axial direction. In the internal space 45, grease is encapsulated. |
