A control valve controls the displacement of a variable displacement compressor. The control valve includes a first valve body for adjusting the pressure in a crank chamber, a pressure sensing member, which is displaced in accordance with the pressure difference between two pressure points located in a refrigerant circuit to move the first valve body, an electromagnetic actuator for urging the pressure sensing member, and a second valve body, which is operably coupled to the pressure sensing member. The second valve body adjusts the opening degree of a discharge passage of the refrigerant circuit in accordance with the displacement of the pressure sensing member. Therefore, compared to a case where the first and second valve bodies are independently arranged in the compressor, the number of parts are reduced, which reduces the manufacturing cost.
