Abstract：
 A method and device for measuring the piston stroke of displacement-variable swashplate compressor features that a pin is inserted in the central hole of shaft neck pin and linked to a transmission rod in the central through hole of mainshaft, and a stroke sensor is connected to another end of said transmission rod. After the displacement of shaft neck pin is measured by the said sensor, the variation of piston stroke can be found out. Its advantages are simple structure, no leakage and high reliability.
