ABSTRACT:
A Venturi is formed in a portion of the passage of a metal tube by drilling an opening in the downstream part of the tube wall at that portion and deforming the metal at the upstream part of the wall inwardly by a cold flow of the metal so as to define a step in that portion with the opening at the downstream end of that step.
