摘要：
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.
