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.
A control valve that has a piston 23 connected to the piston 23 and a cylinder 25 in which the piston 23 slides in the crank chamber 12, and opens and closes according to the pressure of the refrigerant returned to the suction port 29 of the cylinder 25. The return refrigerant or a part of the refrigerant discharged from the piston 23 is guided into the crank chamber 12 by the Cv, and the drive swash plate 13 is tilted due to the pressure difference between the pressure inside the crank chamber 12 and the pressure of the return refrigerant. In a variable capacity compressor whose angle is controlled, the first control valve Cv is opened when the pressure of the return refrigerant is low.
A relatively large diameter cylinder passage 61 communicating between the valve port 40 and the crank chamber 12 is connected to the cylinder 25.
This is a variable capacity swash plate type compressor that was launched in 2013.
