Claims

[Scope of utility model registration request]

In a device that has the function of driving a pulse motor to switch the refrigerant flow path and controlling the flow rate of the refrigerant, after the valve body 12 is fixed to the tip of the valve rod 10 connected to the rotor 4, the inlet flow path 23 A first valve seat 27 is provided on the first flow path 24 side communicating with the rotor, and a first spring 15 and a second spring 1 are provided on both sides of the rotor.
7 and when closing the first valve seat 27, the second spring 17 is applied, and the threaded portion 7 of the feed screw 6 is closed.
and prevents the screw portion 9 of the rotor from being tightened, and when the second valve seat 28 on the second flow path 25 side is closed, the first spring 15 is activated to prevent tightening when the valve is closed. An electric three-way flow control valve characterized by having a structure.
