Document Type and Number:
Japanese Patent JP4041334
Kind Code:
B2
Abstract:
An orifice member 10 disposed at an orifice 32a of a valve body 30 is formed of a material such as stainless steel harder than the aluminummaterial forming valve body 30. Orifice member 10 is substantially cylindrical, with one open end 10a having a flat surface that comes in planar contact with a contact surface of valve body 30 constituting orifice 32a, and the other open end being tapered so as to oppose to a valve member 32d. A screw portion is formed to the outer side of orifice member 10 enabling it to be engaged to a screw portion formed on orifice 32a of valve body 30. The joint can be secured by applying and curing an adhesive between orifice member 10 and orifice 32a. Since orifice member 10 comes in planar contact with valve body 30 having an anodized aluminum film, the film is not damaged by the orifice member.
