A fuel dispensing spout (101) for use in a fuel dispensing nozzle is provided. The fuel dispensing spout (101) includes an inner cylindrical member (103) and an outer cylindrical member (102). The inner (103) and outer (102) cylindrical members are joined by series of ribs (104) which divide the space between the inner (103) an outer (102) members into a plurality of longitudinally and continually extending subchannels (105). Some of the subchannels (105) are utilized for vapor recovery during operation of the spout (101), while one (106) of the subchannels (105) is utilized in detecting pressure increases in captured air contained therein as fuel dispension takes place. The inside passageway (108) defined by the inner cylindrical member (103) is used for carrying fuel that is to be dispensed.

Les élément cylindriques interne (103) et externe (102) sont réunis par des séries de nervures (104) qui divisent l'espace entre les éléments interne (103) et externe (102) en une pluralité de sous-canaux (105) s'étendant longitudinalement et en continu. Certains des sous-canaux (105) sont utilisés pour récupérer la vapeur lors du fonctionnement du tuyau (101) alors qu'un (106) des sous-canaux (105) est utilisé pour détecter les augmentations de pression dans l'air piégé et contenu dans ces sous-canaux lorsque se fait la distribution du combustible. Le passage interne (108) défini par l'élément cylindrique interne (103) est utilisé pour transporter le combustible à distribuer.
