Patent ID: 8052064

Claim:
An expansion valve with a refrigerant flow dividing structure, comprising: a first throttle formed by a first valve body and a first valve hole, wherein the opening degree of the first valve hole is adjusted by the first valve body; a refrigerant flow dividing chamber for dividing refrigerant which has passed through the first throttle into a plurality of flow dividing tubes, the refrigerant flow dividing chamber being formed on a downstream side of the first throttle; flow dividing tube attachment holes which are installed in the refrigerant flow dividing chamber and to which each of the flow dividing tubes is attached; a valve chamber which accommodates the first valve body, the valve chamber being formed on an upstream side of the first throttle; and a cylindrical portion for guiding a refrigerant ejected from the first throttle toward a wall surface opposite to the first throttle, the cylindrical portion being arranged in the refrigerant flow dividing chamber, wherein the flow dividing tube attachment holes are formed in a portion of a sidewall of the refrigerant flow dividing chamber near the first throttle, a flow of the refrigerant ejected from the first throttle collides with a wall body opposite to the first throttle, reverses, and then flows into the flow dividing tubes, and wherein the first throttle is formed integrally with the refrigerant flow dividing chamber.
