Abstract:
To solve problems where a gas-liquid two-phase refrigerant is not continuously and effectively supplied to an orifice part, and a refrigerant flowing sound becomes large.
For solving the problems, this orifice device has a valve body for opening a first passage in a valve chest side wall, a main valve seat 14 for opening a second passage in a valve chest bottom surface, and a main valve element 10 capable of closing the main valve seat 14 in a valve chest. A main orifice part is composed of the main valve element 10 and the main valve seat 14. An auxiliary orifice part using porous permeating materials 12g and 12h is constituted just before or just behind the main orifice part.
