ABSTRACT:
An expansion valve of the present invention has a structure which integrates a refrigerant flow divider. The expansion valve includes a refrigerant flow dividing chamber6on the downstream side of a first throttle10. Flow dividing tubes12are connected to the refrigerant flow dividing chamber6. In the expansion valve, refrigerant which has passed through the first throttle10is sprayed into the refrigerant flow dividing chamber6, so that the flow dividing characteristic of the refrigerant is improved. Also, due to an enlargement of the passage in the refrigerant flow dividing chamber6, the ejection energy of a flow of the refrigerant ejected from the first throttle10is dispersed, whereby a discontinuous refrigerant flow noise is reduced.
