| 摘要 |
The present invention is a control valve that drives a valve body in a valve-closing direction against the resistance of the biasing force of an opening spring and a bellows assembly by means of electromagnetic force arising at an electromagnetic coil unit by means of a pulse-width modulated driving current, wherein the configuration is such that a notched section is formed at an inner peripheral wall of a through hole section provided to the end wall of a solenoid housing, and the magnetic resistance between the peripheral wall of a mobile core housed in a housing member and the inner peripheral wall of the through hole is caused to be different at the notch region and the other regions around the mobile core. Also, a variable capacity compressor controls the refrigerant gas discharge capacity using the control valve. |
