VARIABLE CAPACITY COMPRESSOR

WIPO Patent Application WO/2024/070419

A1

Provided is a variable capacity compressor, wherein the inflow of foreign matter into a capacity control valve that controls the discharge volume of a refrigerant is reduced. A swash plate compressor (100) that is an example of this variable capacity compressor comprises: an intake chamber (150); a compression mechanism that compresses a refrigerant; a discharge chamber (152) to which the refrigerant compressed by the compression mechanism is discharged; a crank chamber (110) that varies the state of the compression mechanism in accordance with internal pressure; a capacity control valve (200) that is disposed in a pressure supply passage (156) which establishes communication between the discharge chamber (152) and the crank chamber (110), and that increases and decreases the flow rate of the refrigerant supplied from the discharge chamber (152) to the crank chamber (110) so as to vary the internal pressure of the crank chamber (110), thereby controlling the discharge volume of the refrigerant; filters (210) that are attached to the periphery of a plurality of entry ports of the capacity control valve (200); and a diversion member that diverts the direction of the refrigerant supplied from a tip opening of the pressure supply passage (156) to the capacity control valve (200).
