Title
(EN) ANTI-RATTLE VALVE, EXHAUST LINE COMPRISING SUCH VALVE AND METHOD FOR MANUFACTURING SUCH VALVE
(FR) VANNE ANTI CLIQUÈTEMENT, LIGNE D'ÉCHAPPEMENT COMPRENANT UNE TELLE VANNE ET PROCÉDÉ DE FABRICATION D'UNE TELLE VANNE
Abstract
(EN) The valve includes a flap (36), a tubular valve body (26) defining a passageway, and a device for guiding the flap (36) relative to the valve body (26) for pivoting the flap (36) relative to the valve body (26) about a pivot axis between a closed position and an open position of the passageway. The guiding device comprises a pin (54) traversed by the pivot axis and comprising a body (74) with a base (76) and, opposite the base (76), a free end (78) resting against the valve body (26). The pin (54) also comprises two lugs (80, 82) each protruding from the base (76) in a direction opposite to the free end (78), said lugs (80, 82) defining between them a slot (84), wherein an edge (86) of the flap (36) is received. The valve further comprises at least one member (90), connected to the flap (36), for plating one of the lugs (80) of the pin (54) against the flap (36).
(FR) Cette vanne comprend un volet (36), un corps de vanne (26) tubulaire définissant un passage, et un dispositif de guidage du volet (36) relativement au corps de vanne (26) pour permettre le pivotement du volet (36) relativement au corps de vanne (26) autour d'un axe de pivotement entre une position d'obturation et une position de libération du passage. Le dispositif de guidage comprend une broche (54) traversée par l'axe de pivotement et comprenant un corps (74) avec une base (76) et, opposée à la base (76), une extrémité libre (78) en appui contre le corps de vanne (26). La broche (54) comprend également deux ergots (80, 82) faisant chacun saillie depuis la base (76) dans une direction opposée à l'extrémité libre (78), lesdits ergots (80, 82) définissant entre eux une fente (84) dans laquelle est reçu un bord (86) du volet (36). La vanne comprend en outre au moins un organe (90), solidaire du volet (36), de plaquage de l'un des ergots (80) de la broche (54) contre ledit volet (36).
