Abstract

Dans un modèle connu de soupape de mise à l'air libre de réservoir, il peut se produire, en particulier dans le cas d'une commande cadencée d'un électro-aimant influençant la position de la soupape de mise à l'air libre, des bruits mécaniques gênants en raison d'un contact entre des pièces métalliques en mouvement relatif les unes par rapport aux autres, ce qui doit être évité. L'organe de fermeture (37) de la soupape présente au moins un élément d'amortissement (35) qui traverse entièrement l'organe de fermeture (37) de la soupape dans le sens axial et qui forme, sur la première face frontale (38) de l'organe de fermeture (37) de la soupape, une première surface d'amortissement (40) dirigée vers le siège (27) de la soupape et, sur la deuxième face frontale (39) de l'organe de fermeture (37) de la soupape, une deuxième surface d'amortissement (41) dirigée vers l'électro-aimant (13), ce qui permet d'éviter ou d'atténuer les chocs de l'organe de fermeture (37) de la soupape sur le siège (27) de la soupape ou le noyau magnétique (15). La soupape de mise à l'air libre objet de l'invention convient pour l'injection de doses de carburant vaporisé, provenant du réservoir de carburant associé à un moteur à combustion interne à compression du mélange et allumage commandé, dans une conduite d'admission dudit moteur à combustion interne.
