1. A fire extinguishing assembly for transforming a liquid into a liquid mist, the assembly comprising: an adapter section having at least one liquid inlet; and a nipple section fixedly in connection with the adapter section, the nipple section comprising: multiple bores extending between an internal duct that connects to the liquid inlet and outlets on an outside of the nipple section, with the bores being positioned radially around the nipple section to direct the liquid radially outward from the nipple section, a deflecting surface for guiding the liquid is positioned around the outlets of the bores; wherein the deflecting surface includes recesses in the form of grooves, ripples or serrations running in a direction from the nipple section to a circumference of the deflecting surface; and the bores and deflecting surface have a mutual positioning so that straight liquid jets flowing through the bores will directly hit the recesses of the deflecting surface in a point of impingement having at least a bevel angle to produce a fine mist.
