Abstract

See full text

A float actuated valve assembly for battery electrolyte replenishment is disclosed. A housing engages an opening in a battery cell. An inlet in the housing is connectable to a water source. A valve in the housing controls the water flow to the cell. The valve is connected by a link to a four bar mechanism that is attached to a float. The float is buoyantly supported and rises and falls in response to the electrolyte level within the cell opening and closing the valve to admit or halt the flow of water to the cell. A baffle prevents fouling of the mechanism by splashing electrolyte. A flash arrester is positioned between the valve and the inlet to quench hydrogen-oxygen explosions between cells. The float is adjustable for different sized cells. A side viewable electrolyte level indicator is provided in the housing. Flash arresters for venting gas are also mounted.
