摘要： A composite relatively flexible resilient flap member has a movable flap and is formed of composite reinforcing fibers such as nylon, carbon or polyester impregnated with elastomeric flexible fuel resistant material. A rigid sheet member formed of composite material comprising reinforcing fibers such as glass, carbon, polyester and nylon and epoxy stiffens the flap. The flap overlies a fuel fill opening in a support plate with a major portion of the flap member fixedly overlying the plate. The flap is offset in an opening of a mounting plate secured to the support plate. The stiffened flap member is preformed with a bend to form a resilient biased hinge when flattened, the hinge being spaced from the fuel fill opening. The flap member and rigid member have low inertia to assist in rapid closure. Other embodiments are disclosed. A fuel cell tank breather vent has a tube with a male valve slug having an elongated shank. The slug length and weight and spring constant of a valve closure spring have values such that the spring is normally compressed by the slug to the valve open state when the vent tube is vertical. When horizontal, the spring immediately closes the slug-O-ring valve.
摘要翻译：复合相对柔性的弹性翼片构件具有活动翼片，并且由复合增强纤维（例如尼龙，碳或聚酯浸渍有弹性柔性耐燃材料）形成。由包括玻璃，碳，聚酯和尼龙的增强纤维和环氧树脂的复合材料形成的刚性片材使得翼片变硬。翼片覆盖在支撑板中的燃料填充开口，其中挡板构件的主要部分固定地覆盖在板上。翼片在固定到支撑板的安装板的开口中偏移。加强的翼片构件被弯曲成形，以在平坦化时形成弹性偏置铰链，铰链与燃料填充开口间隔开。襟翼构件和刚性构件具有低惯性以帮助快速关闭。公开了其他实施例。燃料电池槽通气孔具有带有具有细长柄的阳阀塞的管。阀塞长度和重量和弹簧常数的关闭弹簧具有这样的值，使得当通气管垂直时，弹簧通常被塞子压缩到阀打开状态。当水平时，弹簧立即关闭塞子O型圈阀。
