Abstract
An orifice member disposed at an orifice of a valve body is formed of a material such as stainless steel harder than the aluminum material forming valve body . Orifice member is substantially cylindrical, with one open end having a flat surface that comes in planar contact with a contact surface of valve body constituting orifice , and the other open end being tapered so as to oppose to a valve member . A screw portion is formed to the outer side of orifice member enabling it to be engaged to a screw portion formed on orifice of valve body . The joint can be secured by applying and curing an adhesive between orifice member and orifice . Since orifice member comes in planar contact with valve body having an anodized aluminum film, the film is not damaged by orifice member.
