Title (EN) RESTRICTORS USING THE VENTURI EFFECT
(FR) RESTRICTEURS UTILISANT L'EFFET VENTURI
Abstract:
(EN) Restrictors are disclosed that include a body defining a Venturi tube having a throat defining a junction of a converging inlet cone to a diverging outlet cone along a longitudinal axis thereof, and with the converging inlet cone and the diverging outlet cone each defining an inner passageway that transitions as a hyperbolic or parabolic function toward the throat.
(FR) L'invention concerne des restricteurs, comprenant un corps définissant un tube Venturi ayant un goulot définissant une jonction entre un cône d'entrée convergent et un cône de sortie divergent le long d'un axe longitudinal de celui-ci et le cône d'entrée convergent et le cône de sortie divergent définissant chacun un passage interne qui effectue une transition sous la forme d'une fonction hyperbolique ou parabolique vers le goulot.
