Japanese Patent JP7223836
Kind Code:
B2
Abstract:
An electronic expansion valve, comprising: a valve body (10); a limiting member (20), which is rotatably provided in the valve body (10), is displaced in a vertical direction while rotating, and has two limiting positions in the vertical direction; plastic driving members (30) provided in the valve body (10) and connected to the limiting member (20), so as to drive the limiting member (20) to rotate between the two limiting positions; and a magnetic rotor (90), which is rotatably provided in the valve body (10), and is connected to the plastic driving member (30) in a driving manner, all of the plastic driving members (30) being located in the magnetic rotor (90). By means of the technical solutions above, problems in the prior art that a driving member is made of a metal material, noise occurs when the driving member collides with the limiting member (20), thereby reducing the favorable use experience of the electronic expansion valve are solved.
