A swashplate variable-displacement compressor includes a pressure regulator (30) which comprises a flow control valve (31) including a first spring-loaded, normally-closed spool valve (33) and a pressure chamber (35) accumulating the working pressure used to force the spool valve toward its fully-opened position, and a flow control valve actuating mechanism (32) including a communication passage (40) through which the refrigerant discharge chamber is communicated with the pressure chamber, a second spring-loaded, normally-closed ball pilot valve (41) provided in the communication passage, and an electromagnetic solenoid (42) controlling the opening of the pilot valve (41) so that the opening increases with an increase in exciting current supplied to the solenoid. The pilot valve (41) servces to introduce high-pressure refrigerant gas in the refrigerant discharge chamber (8) into the pressure chamber (35) as the working pressure with the opening controlled by the solenoid. <IMAGE> |
