Filed:

Appl. No.:

6/334156

Inventors:

Gregory L. Howell - Anderson IN

International Classification:

H01M 212

US Classification:

429 88

Abstract:

A flame arrestor for a battery manifold through which gases are vented from cells and liquid is occasionally pumped to replenish electrolyte in the cells comprises two chambers connected by a liquid trap. The trap is connected to each chamber such that liquid tends to drain from the chamber into the trap and thereby seals the trap. The liquid seal suppresses any flame attempting to propagate through the manifold. Gas buildup in the manifold displaces liquid from the trap into the downstream chamber, whereupon gas flows through the chamber for venting and the liquid is returned to the chamber to reform the seal.
