A lighter valve seat member (8) having a cylinfrical member (21), having an internal bore (22), a rebate in the bore to provide a larger diameter bore part (23) and a smaller diameter bore part (24) which forms a valve seat (25). The cylindrical member has an external cylindrical face and a stop is formed on the external face. The external diameter of the cylindrical between the stop and the end of the cylindrical member providing the larger diameter bore part end is substantially constant. A sealing O-ring (14) is held between the stop and a housing (13) into which the cylindrical part of the valve seat member is positioned.
L'invention a trait à un élément siège de clapet de briquet (8) qui comporte un élément cylindrique (21) possédant un alésage interne (22), une feuillure étant creusée dans l'alésage pour former une partie d'alésage de diamètre plus important (23) et une partie d'alésage de diamètre moins important (24) formant un siège de clapet (25). L'élément cylindrique possède une face cylindrique externe, sur laquelle est formée une butée. Le diamètre externe de l'élément cylindrique entre la butée et l'extrémité de l'élément cylindrique formant l'extrémité de la partie d'alésage à diamètre plus important est sensiblement constant. Un joint torique (14) est placé entre la butée et un logement (13) dans lequel la partie cylindrique de l'élément siège de clapet est positionnée.
