Abstract

PURPOSE:To dispense with a bush in such a way that part of a thick diametral pipe is shrunk, and a capillary tube is calked and joined to said shrunk pipe part. CONSTITUTION:Part of a thick diametral pipe 2 is shrunk, a capillary tube 13 is restrained at its outer diameter with the whole part of the inner diametral face of said shrunk pipe part 14, and the both are calked and joined between them. The stepped part 15 has its thicker diameter than the shrunk pipe part 14, it presents a step form with a little narrower diameter than the outer diameter of the thick diametral pipe 12, and it is formed by means of a slight degree of pipe shrinking work. The capillary tube 13 has its tip protruded somewhat more than the tip of the shrunk pipe part of the thick diametral pipe 12, the inside of the shrunk pipe 14 is joined so that it can be a little bitten into the outer diametral face of the capillary tube 13 by means of the shrunk pipe of the thick diametral pipe 12, and is reliably joined and fixed so as not to cause slip- off, leak, etc.
