There is provided a brazing method which makes it possible to rationally perform not only the brazing between a metal member such as a stator made of a magnetic material and a metal member such as a guide pipe made of a non-magnetic material but also the magnetic annealing of these metal members. By making use of a brazing material (90) which can be fused at a lower temperature than a magnetic annealing temperature of metal member (33), the metal member such as a stator made of a magnetic material and the metal member (35) such as a guide pipe made of a non-magnetic material are heated to a predetermined temperature in a furnace to perform the magnetic annealing of the metal member (33) concurrent with the brazing of these metal members.

The sensitivity of a pressure-sensitive element in a pressure-sensitive part of a control valve for variable-capacity compressor is made adjustable by means of an adjusting screw provided so as to permit an adjustment of forward and backward movement with respect to a frame supporting the pressure-sensitive part. The adjusting screw is rotated by engaging an engagement part, which is annexed to a coil assembly constituting a solenoid excitation part, against the adjusting screw thereby to operate the coil assembly.

A valve element disposed in the valve chamber of a control valve body of a control valve for variable capacity compressors performs opening and closing operations by a plunger. The upper end of the valve element of this control valve body is inserted in the pressure chamber, while the lower end of the valve element is inserted in the plunger chamber of the solenoid excitation part. And the plunger chamber and the pressure chamber communicate with each other through a cancel hole formed in this valve element.
