<p>PROBLEM TO BE SOLVED: To prevent thermal distortion of a sliding surface when pipes are joined to a valve body by brazing.SOLUTION: A valve body of a solenoid valve 1 is formed by joining a second valve body 10 and a first valve body 40 by melt-welding W. Pipes 30, 32 are joined to the second valve body 10 by brazing R. A valve element 50 is guided and slides on an inner peripheral face 42 of the first valve body 40. The first valve body 40 is not affected by thermal distortion in brazing R, and good slidability of built-in components is secured.</p> |
