Multiple vent plug assembly
Abstract
Abstract A MULTIPLE VENT PLUG ASSEMBLY FOR ELECTRICAL STORAGE BATTERIES WHICH INCLUDES A BODY COMPOSED OF A BASE, PREFERABLY AN INTEGRAL, UNITARY STRUCTURE, HAVING PERIPHERAL WALLS AND A COVER WITH LATERAL PARTITIONS INSIDE THE BODY DIVIDING IT INTO A PLURALITY OF SEPARATE CHAMBERS. A PLURALITY OF HOLLOW VENT PLUGS, LOCATED ON THE BOTTOM OF THE BASE AND EACH PROVIDED WITH A VENT OPENING INTO THE BATTERY CELL, OPEN INTO THE CHAMBERS. EACH CHAMBER IS PROVIDED WITH AN OUTLET FOR VENTING TO ATMOSPHERE THROUGH THE VASE. THE INTERNAL CONSTRUCTION OF THE CHAMBER AND CONFIGURATION OF THE VENT OUTLET ARE SUCH THAT THE FLOW OF GASES PASSING UPWARD THROUGH THE VENT PLUGS, THROUGH THE CHAMBERS AND OUT THROUGH THE VENT OUTLETS IS SUFFICIENTLY OBSTRUCTED TO PREVENT THE INADVERTENT DISCHARGE OF THE ELECTROLYTE TO ATMOSPHERE AND THE LEAKAGE OF LIQUID ELECTROLYTE THROUGH THE OUTLETS WHEN THE BATTERY IS PARTIALLY TIPPED OR COMPLETELY INVERTED.
