Title:
燃料タンクに溶接可能な蒸発ガス通気バルブ
Document Type and Number:
Japanese Patent JP4446109
Kind Code:
B2
Abstract:
An improved weldable vapor vent valve assembly (118) comprising a non-weldable (heat-resistant) valve body (120) and a weldable connector portion (138) attached to an upper end of the valve body (120) for welding onto the outer surface of a polymeric fuel tank (10). The weldable connector portion (138) secures the valve body in place using vertical anti-leak ribs (134, 135) extending downwardly from the weldable connector (138) and upwardly from the valve body (120) which mate axially in an interlocking, sealing fit. The anti-leak ribs (134, 135) form a labyrinth-type seal that prevents liquid fuel and fuel vapor from leaking between the assembled portions of the vent valve assembly (118).
