Title (EN) A FLUID INDUCTION DEVICE FOR AN ENGINE OF A VEHICLE
(FR) DISPOSITIF D'INDUCTION DE FLUIDE DESTINÉ À UN MOTEUR DE VÉHICULE
Abstract:
(EN) The various embodiments herein provide a fluid induction device 100 comprising a primary tube 104 with a neck portion 122,having a cross-sectional area lesser than that of an inlet 102 and an outlet 108 of the primary tube 104. A secondary tube 106 is coaxially affixed around the outer surface of the primary tube 104 forming an annular chamber 112. Further, at least one orifice 116 is provided on the secondary tube 106 to allow flow of a secondary fluid 118 into the annular chamber 112 from a fluid source. Still further, at least one orifice 114 is provided on the primary tube 104 around the neck portion 122 to induce/draw the secondary fluid 118 from the annular chamber 112 into the primary tube 104 due to venturi effect caused by flow of a primary fluid 120 from the inlet 102 to the outlet 108.
(FR) Les divers modes de réalisation de l'invention concernent un dispositif d'induction de fluide (100) comprenant un tube primaire (104) doté d'une partie de col (122), présentant une aire transversale inférieure à celle d'une entrée (102) et d'une sortie (108) du tube primaire (104). Un tube secondaire (106) est fixé de manière coaxiale autour de la surface externe du tube primaire (104) formant une chambre annulaire (112). En outre, au moins un orifice (116) est prévu sur le tube secondaire (106) de manière à permettre l'écoulement d'un fluide secondaire (118) dans la chambre annulaire (112) depuis une source de fluide. Et en outre, au moins un orifice (114) est prévu sur le tube primaire (104) autour de la partie de col (122) de manière à induire/aspirer le fluide secondaire (118) depuis la chambre annulaire (112) dans le tube primaire (104) en raison de l'effet Venturi provoqué par l'écoulement d'un fluide primaire (120) depuis l'entrée (102) jusqu'à la sortie (108).
