ABSTRACT:
The invention discloses a device for exhausting fumes formed inside accumulators. A chamber formed in the lid of the accumulator communicates with exhaust ducts connected with one another and the accumulator re-fill openings. An anti-explosion paste is located in the chamber and is kept in position by the adherence of a removable cap having a through-going central exhaust opening. A shoulder in the chamber presents a surface against which the anti-explosion paste rests and defines a pre-chamber between the paste and the exhaust duct. The bottom of the pre-chamber has an opening allowing it to communicate with the underlying elements of the accumulator and to drain condensed vapor.
