Planar foam nozzle

摘要

A nozzle for use in a foam gun is designed so that the ports for the two materials both enter the flow passage in the same plane. This serves to eliminate lead/lag flow conditions which result in portions of the material being off-ratio. Counterbored or milled slots encircle the angled sealing surface with the slots machined in from alternating edges of the surface communicating with the respective flow passages for the two (or more) materials.
