Abstract

La présente invention concerne un dispositif formant reniflard pour moteur, dans lequel un espacement prédéterminé (α) est formé entre une surface externe d'une chambre du reniflard (26) située à l'intérieur d'un couvercle de culasse (13) et une surface interne d'un couvercle de culasse (13). L'espacement (α) fonctionne comme un espace d'isolation thermique même si la température de l'air extérieur chute, ce qui empêche les gaz de soufflage de geler dans la chambre du reniflard (26). De plus, une entrée des gaz de soufflage (30) formée dans une surface de paroi de la chambre du reniflard (26) est ouverte à un emplacement en face de la surface interne du couvercle de culasse (13). Non seulement cela augmente le degré de liberté de positionnement pour l'entrée des gaz de soufflage (30) à un niveau supérieur à celui qui est utilisé lorsque l'entrée des gaz de soufflage (30) est ouverte au niveau d'une surface inférieure de la chambre de reniflard (26), mais cela permet également à l'espacement (α) entre la chambre du reniflard (26) et le couvercle de culasse (13) de présenter un bon effet séparateur d'huile, empêchant l'huile d'entrer dans la chambre du reniflard (26).
