    • The explosion attenuating vent cap for storage batteries according to the present invention features an electrolyte drain and baffle design adapted for maximizing return to the battery of any liquid which may enter the vent from vibration, tilting, overheating, overcharge and the like. The vent barrel(s) include a step to assist in closure of the fill openings, and baffles within the vent prevent accumulation of electrolyte within the cap. The arrangement of the entrance to the gas escape passage (leading through an explosion attenuation device such as a disc of microporous polymer) is located on the center lines of the barrel and at the highest possible location within the vent to minimize the intrusion of electrolyte into the attenuation material. This location of the entrance prevents accumulation of electrolyte at that location. Preferably, the vent cap is of the ganged variety, i.e. useful for simultaneously capping three or more fill openings of the battery.
    • 根据本发明的用于蓄电池的爆炸衰减通气帽的特征在于电解液排泄和挡板设计,其适于最大程度地使可能从振动,倾斜,过热,过充电等进入通风口的任何液体的电池返回。 排气筒包括一个辅助关闭填充开口的步骤,并且通气孔内的挡板防止电解液在盖内积聚。 气体排放通道的入口(通过诸如微孔聚合物盘的爆炸衰减装置)的布置位于筒的中心线和通风口内的最高可能位置处,以最小化电解质入侵 衰减材料。 入口处的这个位置防止了电解液在该位置积聚。 优选地,通气盖是组合的,可用于同时封盖电池的三个或更多个填充开口。
