Abstract

See full text

A fluid resistor with a fluid tight structure including two planar members having a surface of each contacting in close proximity. One of the planar members has a laminated structure including a substrate and at least one thin layer of substantially uniform thickness formed on the substrate. A groove extends through the layer. The groove and the surface of the other planar member define a capilliary passageway of substantially constant depth for restricted fluid flow.
