A capacity control valve for modulating the capacity or the pressure of a control chamber by controlling the degree of opening of a valve section with a solenoid coil section via a pressure fluid of said control chamber flowing through the opened passage of said valve section, said control valve comprising: a first valve chamber disposed in said valve section and communicating with a first communicating passage for the discharge pressure Pd; a first valve seat located in the passage between said first valve chamber and said first communicating passage; a third communicating passage for a first control chamber pressure communicating with said control chamber as well as said first valve chamber; a second valve chamber communicating with a fourth communicating passage for a second control chamber pressure which communicates with said control chamber; a second communicating passage for a suction pressure Ps communicating with a chamber of said suction pressure as well as said second valve chamber; a second valve seat located in the passage between said second valve chamber and said second communicating passage; a first valve body disposed within said first valve chamber and having a first valve face which opens or closes against said first valve seat; a second valve body disposed within said second valve chamber and having a second valve face which opens or closes against said first valve seat; a connection rod seating one of said first valve body and said second valve body against the corresponding valve seat while lifting the other valve body away from the corresponding valve seat; and a solenoid coil section driving said first valve body and said second valve body in an opening or a closing direction via a solenoid rod (25, 25A); wherein a controller is adapted to control the solenoid coil section to control a pressure load according to a specified input, said input corresponding to an electric current transmitted to said solenoid coil section, characterized in that said input is defined as a sum of a pressure differential (Pd-Pc1) between said discharge pressure (Pd) and said first control chamber pressure, multiplied by a pressure receiving area of said first valve body receiving said pressure differential between said discharge pressure (Pd) and said first control chamber pressure, and a pressure differential (Pc2-Ps) between a pressure in said second control chamber pressure and said suction pressure (Ps), multiplied by a pressure receiving area of said second valve body receiving said pressure differential between said second control chamber pressure and said suction pressure (Ps). a first valve chamber disposed in said valve section and communicating with a first communicating passage for the discharge pressure Pd; a first valve seat located in the passage between said first valve chamber and said first communicating passage; a third communicating passage for a first control chamber pressure communicating with said control chamber as well as said first valve chamber; a second valve chamber communicating with a fourth communicating passage for a second control chamber pressure which communicates with said control chamber; a second communicating passage for a suction pressure Ps communicating with a chamber of said suction pressure as well as said second valve chamber; a second valve seat located in the passage between said second valve chamber and said second communicating passage; a first valve body disposed within said first valve chamber and having a first valve face which opens or closes against said first valve seat; a second valve body disposed within said second valve chamber and having a second valve face which opens or closes against said first valve seat; a connection rod seating one of said first valve body and said second valve body against the corresponding valve seat while lifting the other valve body away from the corresponding valve seat; and a solenoid coil section driving said first valve body and said second valve body in an opening or a closing direction via a solenoid rod (25, 25A); wherein a controller is adapted to control the solenoid coil section to control a pressure load according to a specified input, said input corresponding to an electric current transmitted to said solenoid coil section, characterized in that said input is defined as a sum of a pressure differential (Pd-Pc1) between said discharge pressure (Pd) and said first control chamber pressure, multiplied by a pressure receiving area of said first valve body receiving said pressure differential between said discharge pressure (Pd) and said first control chamber pressure, and a pressure differential (Pc2-Ps) between a pressure in said second control chamber pressure and said suction pressure (Ps), multiplied by a pressure receiving area of said second valve body receiving said pressure differential between said second control chamber pressure and said suction pressure (Ps).
