Abstract
A fire extinguishing sprinkler nozzle includes a body defining a central channel or bore through which water flows during a fire. The sprinkler nozzle includes a fluid flow thrust reverser disposed over the orifice of the central channel such that water exiting out of the channel impinges the thrust reverser. The direction of water flow is reversed by the thrust reverser. After exiting the thrust reverser, the water impinges the impact surface of deflector disposed around the periphery of the sprinkler body. An upright sprinkler nozzle is thereby provided in which the water has a downward momentum prior to its impinging the impact surface of the deflector that is comparable to a pendent sprinkler head. The sprinkler nozzle is activated by conventional fire detecting or heat sensitive structures.
