FLUID CIRCULATION VALVE

摘要

The invention relates to a valve (1) for regulating the flow of EGR gases in a loop allowing a proportion of the exhaust gases leaving a vehicle combustion engine to be bled off, having a body delimiting an internal duct (2) and comprising a shutter (3) pivot-mounted on an axle (4) dividing said flap (3) into a first part (5) and a second part (6), said flap (3) being able to pivot between an open position that allows gases to pass into the duct (2) and a closed position that prevents said passage, and for which out of the first (5) and second (6) parts, at least one comes into abutment against a support element (7). The first part (5) of the flap has a thickening (9) so as to reduce the passage section for gases between said first part (5) and the support element (7), for angles of opening of said flap (3) that are below a threshold value.

主权项

1. A valve for regulating the flow of the EGR gases in a loop enabling bleeding of some of the exhaust gases leaving a vehicle internal combustion engine, the valve comprising:
a body delimiting an internal duct and including a flap mounted to pivot on an axle separating said flap into a first portion and a second portion, said flap being able to pivot between an open position allowing the passage of the gases in the duct and a closed position preventing said passage, and for which the first portion and the second portion come(s) to abut against a bearing element, the first portion of the flap including a thickened region in order to reduce the gas flow section between said first portion and the bearing element for angles of opening of said flap less than a threshold value.
