PURPOSE: An electronic expansion valve of high-precision and noiseless type is provided to miniaturize a driving part of the electronic expansion valve, and obtain driving force. CONSTITUTION: An electronic expansion valve of high-precision and noiseless type comprises a case(10), a driving part(30), a control part(20), a driving shaft(40), a shaft guide(50), a deceleration part(60), a flow part(70), a yoke shaft(80), and an inlet/outlet part(90). The driving part generates power. The control part reduces resistance when vibrating and rotating of the driving part. The power from the driving part is transferred to the deceleration part, and the deceleration part is rotated. The yoke shaft is inserted into the flow part in a longitudinal direction. Refrigerant flows in/out through the inlet/outlet part.
