摘要： A displacement control valve for a variable displacement compressor. The displacement control valve includes a drive force transmission body, a pressure sensitive chamber, an internal passage, and a valve body. The valve body includes an annular seal which is contactable with a valve seat surface facing toward the first valve body. The drive force transmission body includes a drive rod and a valve body structure having a shaft passage and forming the first valve body. The drive rod is fitted to the shaft passage and coupled to the valve body structure so as to form a gap passage between an outer surface of the drive rod and a wall surface of the shaft passage. The internal passage includes a recess arranged radially inward from the annular seal, the shaft passage, and the gap passage. The gap passage is in direct communication with the recess.

摘要： A control valve used in a variable displacement compressor includes a valve chamber, a valve body and a pressure sensing chamber. A pressure sensing ball is movably located in the pressure sensing chamber and divides the pressure sensing chamber into a first pressure chamber and a second pressure chamber. First and second pressure monitoring points are located in a refrigerant circuit. The first pressure chamber is exposed to the pressure at the first pressure monitoring point. The second pressure chamber is exposed to the pressure at the second pressure monitoring point. The ball is displaced based on the pressure difference between the first pressure chamber and the second pressure chamber. The position of the valve body is determined based on the position of the pressure sensing member.
