Abstract
Embodiments of the invention provide an electronic expansion valve, including a magnetic rotor and a screw rod, and further including an output shaft. The magnetic rotor is surroundingly provided on the output shaft, and the output shaft is slidably connected to the screw rod in an axial direction and drivably connected to the screw rod in a circumferential direction. Since the output shaft is slidably connected to the screw rod in an axial direction and drivably connected to the screw rod in a circumferential direction, the magnetic rotor does not subject to an axial force transmitted by the screw rod and rotates flexibly.
