A nozzle positioning includes a primary pole, a grasping element supported on the upper end of the pole and configured to secure the pole to a surface, and a nozzle mount supported on the grasping element. The nozzle mount is configured to support a nozzle in a substantially horizontal position and to allow the nozzle to rotate about a longitudinal axis perpendicular to the horizontal upper surface of the grasping element. The grasping element is in the form of a hook configured to fit over a window sill or similar structure.

A smart fluid application nozzle consisting of an optical based event locating system, a multi-port nozzle block, and a port switching mechanism is disclosed by the present application. The smart nozzle utilizes a unique arrangement of discharge ports, allowing the angle of the discharge agent to be controlled without moving the nozzle housing. Multiple ports are activated per event to create a uniform fluid distribution within the discharging jet while controlling the discharge angle, which cannot be achieved through a single port discharge. Upon receiving a detection signal, the event locating system determines the spatial location of the event region and activates the appropriate discharge ports, thereby directing agent toward the event zone and applying fluid while minimizing damage to nearby areas. The use of the system may be used wherever the precise directed application of as fluid is desired including, fire suppression.

A nozzle of a fire suppression system includes a housing. Two or more orifices in the housing emit a fire suppression agent. Each of the two or more orifices emits the fire suppression agent in a rotational vortex.

The present invention relates to a spray of microjets emanating at an inclined angle from nozzles comprised in a substantially planar membrane layer. A spray nozzle unit for spraying a plurality of fluidic microjets from a pressurized liquid comprises a substantially planar (semiconductor) support having an upstream surface and a downstream surface, and a spray membrane layer arranged on the downstream surface of the support. The spray membrane layer comprises a plurality of nozzle orifices each configured for spraying a fluidic microjet in a Rayleigh regime. Thee support defines a cavity extending from the upstream surface to the spray membrane layer. The cavity is in fluid communication with each one of the nozzle orifices for supplying the pressurized liquid to the nozzle orifices. A position of the nozzle orifices, seen along a direction perpendicular to the downstream surface, is offset in respect of a centre of the cavity. At least two of the nozzle orifices exhibit a different offset in respect of the centre of the cavity.

A hydraulically propelled drone is provided for delivering firefighting fluid to an elevated location. The drone comprises a housing having a primary inlet configured to receive the distal end of a fire hose, a primary outlet configured to receive the inlet end of a primary nozzle, a central passageway configured to conduct fluid from the primary inlet to the primary outlet, and at least one secondary outlet communicating with the central passageway. At least one lift nozzle communicates with the secondary outlet and is configured to direct fluid in a generally downward direction so as to produce an upward thrust on the drone housing, and at least one valve is contained within the housing and configured to control the flow of said fluid through the primary nozzle and the at least one lift nozzle nozzle.
