The present invention relates to a variable displacement swash plate type compressor with a flow rate detecting unit (600) which comprises a moving rod (610) coupled to a rotary shaft (200), integrally rotated along with the rotary shaft (200), penetrating a valve unit (500), and axially moving when linked with a variation in the angle of a swash plate (300); a sensing body (620) axially moving when linked with the moving rod (600), having one side to which an actuating force from the moving rod (610) and pressure of a suction chamber (132) are applied, and having the other side to which pressure of a discharge chamber (134) is applied; and a sensor (630) installed on a rear head (130), facing the sensing body (620), and sensing the access or the separation of the sensing body (620). According to the present invention, a torque estimation value approximating the actual torque of the variable displacement swash plate type compressor can be obtained, thereby efficiently controlling an engine torque. In addition, a sensing part is installed inside a rear housing without an extra throttle part, so the deterioration of a flow rate is prevented and the accuracy of a measurement value is maintained even if the flow rate is low, thereby accurately measuring the discharge amount of the refrigerant. |
