A complete Ultra High pressure (UHP) nozzle is coupled to a fluid source. A fluid management system comprised of an engine driven, UHP pump, connected to an UHP hose line. The fluid discharged from the UHP nozzle will deliver the optimum fluid droplet size allowing for the optimum disruption of the fire (science) triangle. The optimum fluid droplet size (diameter) greater than, or equal to, 70-160 microns, addressing the fire suppression stages, resulting in the effective and efficient fire attack, suppression, and overhaul.

A gardening water spray gun may include a main body, a water guiding tube, a guiding sleeve, an axle shaft, a nozzle cap, a control ring, a spray head and a block ring. The water spray gun of the present invention not only has the functions of garden watering and item washing but also is configured to provide powerful and wide-range water stream as a water bloom, which is configured to easily remove dust and dirt attached on the wall or floor and improve the practicability of the water spray gun.

A sanitary fitted element (1) which can be inserted into the water outlet of a sanitary outlet fitting and is held releasably there. A characteristic feature of the fitted element (1) according to the invention is that said fitted element has an adjusting device for changing the clear sectional area of flow of the fitted element (1) and/or the discharge rate, which adjusting device is actuable via at least one control element (8) which is arranged actuably on the inflow side of the fitted element (1) and/or on the outflow side thereof. The fitted element (1) according to the invention can be used in a versatile manner in order to reduce the outlay on production and stock.

A multi-cone, multi-stage spray nozzle includes a nozzle body and outer and inner valve stems. The nozzle body defines an outer valve seat disposed at its distal end. The outer valve stem is slidably disposed in the nozzle body. The inner valve stem is slidably disposed in the outer valve stem. The inner valve stem occupies an open position and the outer valve stem occupies a closed position upon the application of a first pressure on the distal ends of the inner and outer valve stems. And, the inner and outer valve stems both occupy open positions upon the application of a second pressure that is greater than the first pressure on the distal ends of the inner and outer valve stems.

A hand held supersonic air knife with a supersonic variable flow nozzle yields a continuously variable power mass flow rate (CFM) and pressure over a selectable power range, responsive to rotations of the nozzle exterior sleeve or outer nozzle member. The maximum power position identified as one end position and a second end position as the lowest power. The exterior sleeve can be rotated to any axial or circumferential position between start (low) and end (high). The result will be an intermediate power position. Any intermediate position will also be a supersonic nozzle of varying parameters between the start and end positions. Thus, a variable flow supersonic nozzle is provided by the manual sleeve rotation by an operator or a remotely controlled positioning of the sleeve.

A water nozzle with a flow head is provided with at least two separate water supply devices that supply, in a controllable fashion, different water volume flows to the flow head. The flow head generates an annular jet from the different water volume flows. By controlling the water volume flows, alternatively a slim annular jet or a widened annular jet is generated by the flow head. A deflection element with a central outlet opening is provided, wherein the central outlet opening is arranged in a flow direction of the annular jet downstream of and spaced apart from the flow head. A deflection device surrounds the central outlet opening. A diameter of the central outlet opening is designed such that the slim annular jet is able to pass through the central outlet opening while the widened annular jet impacts on the deflection device surrounding the central outlet opening.

A water injector assembly includes an injector body having a substantially hollow interior. The injector body defines an inlet opening defined within an outer radial surface of the injector body at a first axial location along the injector body. The injector body defines a flowpath opening in fluid communication with the inlet opening such that the flowpath opening is configured to receive the fluid from the inlet opening. The injector body defines an outlet opening defined within the injector body at a second axial location along the injector body. The outlet opening is in fluid communication with the flowpath opening, such that the outlet opening receives the fluid from the flowpath opening. The second axial location of the outlet opening is different than the first axial location of the inlet opening.
