Claims

[Scope of utility model registration request]

Between the outdoor heat exchanger ■ such as a heat pump circuit and the indoor heat exchanger ■, the rotation of the motor rotor ■ is converted into linear motion of the valve shaft [phase] by the screw part 6 ■, and the needle valve ■ The degree of throttling of the refrigerant is adjusted by the opening degree of the valve, and one inlet and outlet (■) is provided at the tip of the needle-shaped valve as the refrigerant inlet and outlet, and the other is in the valve body so as to be perpendicular to the valve shaft [phase]. When installing the electric expansion valve ■ with an inlet and outlet 0■ on the zero side, the flow direction of the refrigerant during cooling operation should be changed so that after it flows into the valve body 0 from the inlet and outlet Q of the electric expansion valve ■, the throttle part ■ is A mounting structure for an electrically operated expansion valve, characterized in that the air flows out through an inlet/outlet 0 provided at the tip of the needle valve (2).
