MOTOR VEHICLE WITH AN EXHAUST GAS RECIRCULATION SYSTEM HAVING A POPPET VALVE

Exhaust gas recirculation circuit comprising: at least one valve (100) comprising a body defining a first duct (1) opening into a second duct (2) thereby defining an intersection that forms a seat (7) at right angles to the second duct (2), a valve disk (8) that slides in the first duct (1) at right...

Beschreibung
Zusammenfassung:	Exhaust gas recirculation circuit comprising: at least one valve (100) comprising a body defining a first duct (1) opening into a second duct (2) thereby defining an intersection that forms a seat (7) at right angles to the second duct (2), a valve disk (8) that slides in the first duct (1) at right angles to the seat(7) between a closed position and an open position in which the valve disk (8) lies into close proximity to a wall (5) of the first duct (1) lying facing the seat (7), the valve (100) comprising means of actuating (12) the valve disk (8) from its closed position to its open position and an elastic spring mechanism bringing the valve disk (8) to its closed position, an exhaust pipe (24) connected to the first duct (1) of the valve (100), an intake pipe (31) connected to the second duct (2) of the valve (100), the circuit being arranged to define a flow direction for a gas flow from the first duct (1) to the second duct (2) in such a manner as the gas flow tends to bring the valve disk (8) in the closed position at least when the valve disk (8) lies into close proximity to its closed position.
