Pendent-type diffuser impingement water mist nozzle

Abstract

A pendent-type diffuser impingement water mist fire protection nozzle has a body defining an orifice and an outlet for flow of water from a source. The orifice defines an axis, and the outlet is disposed generally coaxial with the orifice. A diffuser is disposed generally coaxial with the axis of the orifice and defines a diffuser inner surface positioned for impingement of the flow of water thereupon and an opposite outer surface. The diffuser has a plurality of tines distributed about a diffuser periphery and defining a plurality of openings therebetween. The diffuser inner surface defines at least one channel extending along the inner surface of the diffuser toward a predetermined region of the diffuser periphery, preferably positioned to collect water impinging thereupon and to divert collected water toward the predetermined region of the diffuser periphery.
