Summary: | Provided is a control valve for a variable capacity compressor which carries out a PWM current flow control to restrain noise due to micro-vibration of a plunger. A solenoid (3) includes a core (42) fixed to a body (5); a sleeve (44) fixed to the core (42) to form an inner space (45) which is blocked from the air by sealing an end portion of the core (42) and is communicated with the inside of the body (5) to introduce refrigerant; and a plunger (46) which is accommodated in the inner space (45), is arranged opposite to the core (42) in the axial direction, and is displaceable and integrally formed with a valve body (33) in the axial direction. Grease is stored and sealed in the inner space (45). |
