PROBLEM TO BE SOLVED: To provide an expansion valve having a refrigerant flow dividing chamber-integrated structure and a refrigerating device using the same, capable of simplifying a refrigerant circuit, reducing refrigerant flow noise and improving a refrigerant flow dividing effect by forming the refrigerant flow dividing chamber integrally with the expansion valve, and further reducing refrigerant flow noise by a buffering member. SOLUTION: This expansion valve comprises a throttle portion 10 composed of a valve element 13 and a valve hole 11, the refrigerant flow dividing chamber 7 for dividing the refrigerant after passing through the throttle portion 10, to a flow dividing pipe, and buffering members 20, 21 for absorbing or damping impact shock by the refrigerant flow. The buffering members 20, 21 are mounted in a state of covering the circumference of the valve hole 11 on a valve hole forming wall 5 forming at least the valve hole 11. COPYRIGHT: (C)2009,JPO&INPIT
