PROBLEM TO BE SOLVED: To provide a control valve for a variable capacity compressor with a pressure sensing part in the central part in which a bleed function is exhibited effectively.SOLUTION: A control valve 1 includes: a body 5 with a main passage and a sub-passage formed thereon; a main valve seat 20 provided in the main passage; a main valve body 32 attached/detached to/from the main valve seat 20, and opening/closing a main valve; an auxiliary valve seat 36 provided in the sub-passage; an auxiliary valve body 38 attached/detached to/from the auxiliary valve seat 36, and opening/closing an auxiliary valve; a power element 6 sensing a suction pressure Ps, and generating a driving force in the valve opening direction of the main valve according to the magnitude of the suction pressure Ps; and a solenoid 3 generating the driving force in the closed valve direction of the main valve according to the amount of current supplied. Then, the main valve, the power element 6, the auxiliary valve and the solenoid 3 are sequentially arranged from one end of the body 5. The control valve 1 further includes a forced valve opening mechanism to forcibly open the auxiliary valve by using the driving force of the solenoid 3. |
