A hose end spray head apparatus includes a spread head body and a hose coupling. The spray head body includes a mixing body and a spray outlet arm formed as a unitary construction. The spray outlet arm extends outwardly from the mixing body and includes a spray bore to discharge a mixed fluid. The spray bore communicates with atmosphere via a first radial sidewall bore and a first offset top surface bore. An axial bottom surface bore extends from the bottom surface to the spray bore and is draws product from a container so as to inject the product into the spray bore. A second radial sidewall bore is configured to communicate an open interior of the container with atmosphere. The hose coupling is secured to the mixing body and mounts to a fluid supply to form the mixed fluid which is discharged through the spray bore.

A fire protection nozzle includes a body having two frame arms having proximal ends connected to an outlet of the body, and distal ends, the two frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms, the junction including a central bore and an outer wall. A deflector is mounted to the body, and includes a planar member having a mounting hole in a center of the planar member to receive the outer wall of the junction, and a plurality of slots on a periphery of the planar member. The plurality of slots includes first slots, second slots, third slots, and fourth slots.

A spray head has an inlet in fluid communication with a plurality of nozzles. The nozzles are adapted to produce, in use, a jet of fluid which is directed toward a respective impingement surface portion. The jet of fluid impacts on the respective impingement surface portion and breaks into a stream of droplets. The stream of droplets has an elongate transverse cross-section.

A nozzle for a filter cleaning system has a stub portion having an inlet opening and an outlet opening, and a splitter portion positioned downstream of the stub portion. The splitter portion has deflector surfaces arranged to direct the airflow exiting the stub portion outlet in 3 or more different/separate airstreams each of which airstreams are directed inclined axially outwardly from the axial direction of the airflow exiting the stub portion outlet opening. The various parameters of the splitter nozzle portion can be tailored to provide required jet shape and entrainment characteristics. A beneficial feature of the nozzle designs is that jet entrainment and recombination of flows can be specified for different shaped filters.

A concealable sprinkler head includes a frame having a body mountable to a fire suppression liquid source, a pair of frame arms and a pair of corresponding drop pins slidably engaged with a respective frame arm. A thermal trigger is supported within the sprinkler frame. A fluid deflector is secured to the drop pins and includes a generally horizontal surface. The drop pins extend substantially orthogonally from the horizontal surface. An inclined surface of the fluid deflector extends angularly upwardly from the horizontal surface. A concealing cup surrounds the frame arms. A cover plate is attached to the concealing cup, covering the distal end thereof, wherein the drop pins and the deflector are positioned within the concealing cup. The cover plate is removable from the concealing cup permitting the drop pins and the deflector to axially slide out of the concealing cup into an operational position.

A fire suppression system in which side-discharge fire sprinklers are fitted to opposite sides of a supply line and aimed so that their coverage areas point in opposite directions. The fire sprinklers are alternated on left and right-hand sides of the supply line, and are spaced apart at a consistent interval. Each fire sprinkler includes a deflector configured to disperse the outflow of water over a non-circular coverage area. When two supply lines are installed next to each other so that half of the sprinklers on one supply line point toward the other supply line, and vise versa, the fire sprinklers are staggered so that their respective coverage areas are interlaced in the intermediate space.

A fluid dispensing nozzle includes a housing including an outlet to discharge fluid to a surrounding environment. The fluid dispensing nozzle also includes a nozzle insert disposed in the housing and including an inlet in fluid communication with a source of fluid to receive a fluid flow. The nozzle insert includes an outlet orifice in fluid communication with the outlet to direct fluid from the inlet toward the outlet. The nozzle insert is selectively movable relative to the housing between a first position in which fluid is discharged through the outlet at a first flow rate and a second position in which the fluid is discharged through the outlet at a second flow rate larger than the first flow rate. The nozzle insert is movable between the first position and the second position independent of the pressure of fluid at the inlet.

A concealed sprinkler includes a sprinkler body having a flow passage therethrough with an inlet end and an outlet end. A closure device is secured at the outlet end of the flow passage by a heat responsive trigger. A deflector assembly includes a deflector plate and a button secured to an upstream side of the deflector plate. The deflector assembly is movably supported to the sprinkler body by at least one arm. The button defines an aperture that extends unobstructed all the way through the button from an upstream side to a downstream side.

Systems and methods for containing fluid splash include using a fluid flow spaced from a vessel and/or fluid surface to effectively trap materials from a fluid stream flowing through the fluid flow. The fluid flow creates a spray envelope in connection with the fluid surface and/or vessel and substantially prevents droplets of the fluid stream from exiting the vessel. The fluid flow is created by allowing a supply fluid to flow through a nozzle oriented to cast a spray pattern into the vessel and/or into contact with the fluid surface. The fluid flow may be selectively activated and deactivated and/or be automatically (e.g., light or motion) activated and deactivated.

A nozzle is provided having a low precipitation rate and uniform fluid distribution to a desired arcuate span of coverage. The nozzle has an inflow port having a shape corresponding to the desired arc of coverage and a size for effecting a low precipitation rate. The nozzle also has a deflector surface with a water distribution profile including ribs for subdividing the fluid into multiple sets of fluid streams. There are at least two fluid streams for distant and close-in irrigation to provide relatively uniform distribution and coverage. The nozzle may be a unitary, one-piece, molded nozzle body including a mounting portion, an inflow port, and a deflector portion.
