FLAME ARRESTER

摘要

The present invention relates to a flame arrester for internal combustion engines, which is installed in a port of a crank case of a main engine and a sub-engine of a ship or another vehicle. In the flame arrester of the present invention, a plurality of embossments of a flame arresting unit, which is formed by layering a plurality of metal strips for arresting flame belching from the crank case, are circumferentially placed such that they are inclined relative to a radial axis of the flame arresting unit, thus increasing the flame transferring distance and flame heat dissipating and cooling surface area, and realizing exclusion of oxygen, thereby efficiently arresting flame.
