  "textContent": "A control valve (CV) is located in a variable displacement compressor that is installed in a refrigerant circuit. The control valve (CV) operates such that the pressure difference between first and second pressure monitoring points (P1, P2) in the refrigerant circuit seeks a predetermined target value. The first pressure monitoring point (P1) is located in a discharge chamber (22) of the compressor. The second pressure monitoring point (P2) is located in a flow pipe (36) that extends from the discharge chamber (22). The static pressure of refrigerant in the discharge chamber is introduced into a control valve (CV) from the first pressure monitoring point (P1). A pressure that includes the static pressure and the dynamic pressure of refrigerant in the flow pipe (36) is introduced into the control valve (CV) from the second pressure monitoring point (P2) . As a result, the displacement of the compressor is reliably controlled without being affected by the thermal load of an evaporator (33).",
