Kind Code:
A1
Abstract:
Provided is a magnetic rotor assembly, which comprises: a rotor (20) that has a mounting hole (21) provided on an end surface thereof; a stopper (30), wherein the stopper (30) is arranged inside the rotor (20) and rotates synchronously with the rotor (20), an end surface of the stopper (30) is provided with a protrusion (31), the protrusion (31) extends into the mounting hole (21), and one end of the protrusion (31) running through the mounting hole (21) is provided with a block flange (32) for blocking the protrusion (31) from exiting the mounting hole (21). The described structure solves the problem of severe deformation of a stopper during injection molding of an electronic expansion valve in the prior art. At the same time, an electronic expansion valve comprising said magnetic rotor assembly is disclosed.
