PROBLEM TO BE SOLVED: To provide an expansion valve which can easily and arbitrarily obtain the flow control property of a flow control part.SOLUTION: A power element 34 is filled with first fluid, and a second power element 35 is filled with second fluid different from the first fluid. A valve mechanism part 32 controls the flow of refrigerant in a first refrigerant passage 36 depending on the total expansion amount of the first power element 34 and the second power element 35. The flow control property of the valve mechanism part 32 is, therefore, intermediate one, as a whole, between first flow control property given only by the first power element 34 filled with the first fluid and second flow control property given only by the second power element 35 filled with the second fluid. As a result, the flow control property of the valve mechanism part 32 can be easily and arbitrarily obtained. |
