<p>Disclosed is a device for measuring a coolant discharge amount of a compressor, which can control torque to be in an optimized state during operation of a compressor and minimize a loss of an unnecessary driving force thereby by installing a bypass path branched from the main discharging path of a compressor coolant and more precisely detecting a discharge amount from detection of a magnetic flux density with respect to a spool valve changed in accordance with the discharge amount of a coolant on the bypass path. The device for measuring a coolant discharge amount as described above comprises: a main discharge passage (300) communicating with a discharge chamber (262) of the compressor (100); a bypass passage (310) branched from the main discharge passage (300) to be merged into the main discharge passage (300); a chamber (320) formed in the bypass passage (310); a spool valve (330) installed in the chamber (320) to variably control deposition in accordance with a flow rate of the coolant; a magnetic body (340) installed in the spool valve (330); and a magnetic sensor (350) sensing a change of the magnetic flux density accompanies with the deposition of the magnetic body (340).</p> |
