Abstract
Provided is a variable-capacity compressor control valve with a simple configuration that can increase the attraction force of an electromagnetic actuator and thus can reduce the size of the control valve. A sub valve element that is a magnetic body made of the same magnetic material as or a different magnetic material from that of a plunger, which is adapted to move a main valve element in the direction to open or close the valve orifice, is fitted in and fixed to the plunger.
