<p><P>PROBLEM TO BE SOLVED: To provide a tube material for stabilizing the quality, an expansion unit provided with the tube material, and a refrigerant circuit module provided with the expansion unit. <P>SOLUTION: The capillary tube 27 is equipped with one end part 27a, an intermediate part 27b, and the other end part 27c. The part 27a comprises tube parts 30, 31, 32, the part 27b comprises a tube 33, and the part 27c comprises tube parts 34, 35. The tube part 31 has the largest inside diameter, and serves as a silencing part. The part 33 has the smallest inside diameter, and serves as an expansion valve. The tube parts 30, 31, 32, 33, 34, 35 are formed so that the fibrous structure is made continuous in neighboring parts. That is, the tube parts 30, 31, 32, 33, 34, 35 are formed by rolling/drawing work. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
