LOW SILHOUETTE VENTING SYSTEM FOR ELECTRIC STORAGE BATTERY

摘要

LOW SILHOUETTE VENTING SYSTEM FOR ELECTRIC STORAGE BATTERY A low silhouette horizontal-type venting system for an electric storage battery including an electrolyte drainage aperture(s) at one end of the system, an exhaust port at the other end of the system and an electrolyte trapping and refluxing chamber between the aperture(s) and port wherein the chamber is divided into an antechamber and a sump chamber having oppositely sloping floors leading downwardly to the drainage aperture. A narrow electrolyte upflow restricting slot(s) communicates the antechamber with the sump chamber. Baffles are provided in the sump chamber to inhibit electrolyte movement therethrough. Narrow channels are provided at the slot(s) and drainage aperture(s) for capillarily refluxing electrolyte back to the sump and cell, respectively.
