容量可変斜板式コンプレツサ。 A drive swash plate 13 is connected to the drive shaft 11 so that its inclination angle can be changed; and a drive swash plate 13 is slidably attached to the drive swash plate 13 and reciprocated in the axial direction by rotation of the drive swash plate 13. Rotating wobble board 1
6, and a piston rod 22 on this wobble plate 16.
The crank chamber 12 has a piston 23 connected to the piston 23 and a cylinder 25 in which the piston 23 slides. A control valve Cv that is opened and closed by a control valve is provided, and by opening and closing the control valve Cv, the return refrigerant or a part of the refrigerant discharged from the piston 23 is guided into the crank chamber 12, and the pressure inside the crank chamber 12 is reduced. In the variable capacity compressor which generates a pressure difference in the pressure of the return refrigerant and controls the inclination angle of the drive swash plate 13, the valve port 40 of the control valve Cv is configured such that:
It has a plurality of openings each having a different inner diameter,
A variable capacity swash plate type compressor, characterized in that the opening degree of the valve port can be changed in multiple stages by control operation of the control valve.
