PURPOSE: An expansion valve is provided to reduce noise by decompressing refrigerants of a refrigeration cycle and controlling the flow rate of the refrigerants. CONSTITUTION: An expansion valve comprises a valve body(30) and a rectifying member(100). The valve body comprises an inlet port(321), an outlet port(331), and a valve member(32b). High-pressure refrigerants flow through the inlet and outlet ports. The valve member is formed in a valve chamber(35) and controls the opening degree of a valve hole(32a). The rectifying member is formed in the inlet port and subdivides bubbles contained in the high-pressure refrigerants. The subdivided bubbles are rectified and pass through the inside the valve body. |
