Document Type and Number:
WIPO Patent Application WO/2021/253985
Kind Code:
A1
Abstract:
An electronic expansion valve, comprising a magnetic rotor (10), a connection member (20), a position-limiting member (30), a screw rod (40), and a guide shaft (50). The connection member (20) is fixedly disposed in the magnetic rotor (10) and has a first fitting hole (21). The connection member (20) is an injection molding structure. The position-limiting member (30) fits with the connection member (20) and limits the position thereof, and has a second fitting hole (31) corresponding to the first fitting hole (21). The screw rod (40) passes through the first fitting hole (21), and is fixedly connected to an inner wall of the second fitting hole (31). The guide shaft (50) is fixedly disposed on an inner wall of the magnetic rotor (10), and extends inside the magnetic rotor (10) in the axial direction of the magnetic rotor (10).
