Abstract
Official abstract text for this publication.
In order to provide a fluid resistance device that is easily manufactured, compact, accurate, and uniform in performance, the fluid resistance device comprises two members that have facing surfaces that face each other and a downstream end of the upstream side flow channel and an upstream end of the downstream side flow channel open at positions displaced from each other on the facing surfaces, and a ring body that is arranged to surround the downstream end opening and the upstream end opening and that forms the fluid resistance channel between the downstream end opening and the upstream end opening by being sandwiched by the facing surfaces, and is so configured that the ring body is made of a material harder than that of each member, and the ring body breaks into the facing surfaces by fastening two members so as to make the facing surfaces approach each other.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fluid resistance device where an upstream side flow channel, a downstream side flow channel and a fluid resistance channel that connects these flow channels are formed, comprising two members that have facing surfaces that face each other and a downstream end of the upstream side flow channel and an upstream end of the downstream side flow channel open respectively at a downstream end opening and an upstream end opening at positions displaced from ea…
