特徴とする圧縮機の能力制御弁。 A pressure displacement converting section 6 that proportionally converts fluid pressure into displacement, a two-way valve section 8 that outputs an intermediate pressure AP using the pressure difference between the high pressure side pressure HP and the low pressure side pressure LP, and the intermediate pressure AP. In a compressor capacity control valve consisting of a return section 7 for feeding back, a correction shaft 70 having a seal section is disposed between the ball 33 of the two-way valve section 8 and the high pressure side pressure HP communication hole 72 to reduce the chamber. 66 and a chamber 67, and the chamber 67 is formed through a hole 68 and an orifice 69 provided in the correction shaft 70.
supplying fluid to the chamber 66 from
A capacity control valve for a compressor, comprising a correction section 49 configured to apply high pressure side pressure HP directly to a correction shaft 70.
