1. A variable-capacity compressor control valve comprising:

  • a valve body including a valve chamber with a valve orifice, a Ps inlet/outlet port communicating with a suction chamber of a compressor, a Pd introduction port arranged upstream of the valve orifice and communicating with a discharge chamber of the compressor, and a Pc inlet/outlet port arranged downstream of the valve orifice and communicating with a crank chamber of the compressor;

    a valve element adapted to open or close the valve orifice;

    an electromagnetic actuator including a plunger and adapted to move the valve element in a direction to open or close the valve orifice;

    a pressure-sensitive chamber adapted to receive a suction pressure Ps from the compressor via the Ps inlet/outlet port; and

    a pressure-sensitive reaction member arranged in the pressure-sensitive chamber and adapted to urge the valve element in the direction to open or close the valve orifice in accordance with a pressure in the pressure-sensitive chamber,wherein;

    the electromagnetic actuator includes a cylindrical stator, an attractor, and the plunger arranged in series on an inner peripheral side of a coil,a closure member adapted to close an opening of the stator on a side opposite to the attractor is press-fitted into the opening in a contracting and expanding direction of the pressure-sensitive reaction member and welded therein so as to form the pressure-sensitive chamber on an inner peripheral side of the stator, andthe stator and the attractor are integrally molded.
