A nozzle for a fire suppression system includes a smooth dome having an exterior surface approximating a partial sphere, a cavity within the dome, and a plurality of orifices through the dome providing fluid communication between the cavity and the exterior of the dome. A fire suppression system is also disclosed.

A nozzle assembly includes a nozzle body and a flow straightener. The nozzle body defines an inlet configured to be fluidly coupled to fluid source, an outlet, and a nozzle body passage extending between the inlet and the outlet. The flow straightener is coupled to the nozzle body and extends at least partially across the nozzle body passage. The flow straightener defines a primary passage and a secondary passage extending through the flow straightener to fluidly couple the inlet and the outlet of the nozzle body. The primary passage defines a primary passage outlet having a cross-sectional area, and the secondary passage defines a secondary passage outlet having a cross-sectional area that is less than the cross-sectional area of the at least one primary passage. At least one of the primary passage outlet and the secondary passage outlet has a circular cross-section.

A multi-directional fire extinguishing nozzle is disclosed. The multi-directional fire extinguishing nozzle may comprise a pylon fitting configured to receive a fire extinguishing agent. The multi-directional fire extinguishing nozzle may comprise a hose fitting coupled to the pylon fitting via a coupling nut. The multi-directional fire extinguishing nozzle may comprise a plurality of fluid distribution outlets configured to deliver the fire extinguishing agent. The fluid distribution outlets may define voids on the surface of the coupling nut, and extending through the coupling nut and the hose fitting.

An atomizer nozzle for the automatically dispensing of a liquid comprises: a main body; a dispensing head; and a locking assembly. The main body comprises: an inlet configured to be supplied with the liquid; an outlet; and a cavity extending from the inlet to the outlet. The dispensing head, movable along the cavity, is configured to dispense the liquid beyond the outlet, outside the atomizer nozzle. The locking assembly comprises a thermosensitive element configured to break at a predetermined temperature. The locking assembly is configured to: lock the dispensing head in a locked position at a distance from the outlet; and automatically release the dispensing head from the locked position when the thermosensitive element reaches the predetermined temperature. The dispensing head is further configured to move along the cavity when released, thereby reducing the distance until it is eliminated, and to dispense the liquid by protruding from the outlet.

The current disclosure describes car parking garages, water mist fire protection systems for car parking garages, methods and water mist sprinklers therefor, the car parking garage system (10) comprising a floor deck (50) and a ceiling deck (51) spaced about a longitudinal axis (A) extending parallel to the ceiling deck (51), defining an effective height range (H1) between the floor deck (50) and the ceiling (51) deck in a direction perpendicular to the longitudinal axis (A); and a fire protection system including a supply pipe system (30) having a parallel portion (31) disposed parallel to the longitudinal axis (A); and at least one water mist sprinkler (100) coupled to the parallel portion (31) of the supply pipe system (30), the at least one water mist sprinkler (100) including a frame body (110) having an inlet (111) for receipt of an extinguishing fluid from the supply pipe system (30), an outlet (113) with a passageway (112) extending between the inlet (111) and the outlet (113) to define a discharge coefficient of a nominal metric K-factor of below 32, a seal assembly (114) and a heat-responsive trigger (115) to support the seal assembly (114) in the outlet (113); and a deflector (120) coupled to the frame body (110) and spaced from the outlet (113) for distribution of the extinguishing fluid; wherein the effective height range (H1) is up to 4 meters.

The invention includes components and methodology for fixed and semi-fixed systems for extinguishing fire in large industrial flammable liquid storage tanks, including aerated foam projecting nozzles discharging substantially focused streams together with aeration chambers and risers and the formation of wand heads and wands. Specifically, the invention includes a nozzle having a tip portion, the tip portion having a stream shaper, and the stream shaper having at least four fins with a longitudinal dimension in the tip portion greater than a radial dimension in the tip portion.
