A two-part spray nozzle with body and head parts which are joined together is disclosed. The body and head include channels in planar surfaces which are ultimately joined with the channels in alignment. An elastomer, preferably having a cylindrical shape is inserted into the channel to provide a fluid tight seal between the head and body.

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 corridor sprinkler includes a frame, a seal, a thermally-responsive trigger, and a deflector. The frame defines a passageway between an inlet and an outlet along a longitudinal axis, the passageway having a nominal K-factor greater than or equal to 8.0. The seal is coupled with the outlet to prevent fluid flow out of the passageway while the seal is in an unactuated state. The thermally-responsive trigger changes the seal from the unactuated state to an actuated state to allow fluid to flow out of the passageway. The deflector is coupled with the frame and distributes fluid received at the inlet at a pressure of between 8 psi and 250 psi and through the passageway to provide a coverage area of between 220 square feet and 400 square feet and a polygonal spray pattern with a long axis length of between 28 feet to 36 feet.

A fire protection system includes a plurality of fluid distribution devices coupled to the fluid supply pipes to define four fluid distribution devices above a floor. The fluid distribution devices generate a spray pattern overlapping one another to define a rectangular fluid distribution area 2.5 ft. The rectangular area having a first pair of edges extending parallel to the fluid supply pipes and a second pair of edge extending perpendicular to the first edge. The fluid distribution devices are axially aligned above a corner of the rectangular area, the fluid distribution area defined by a grid of one square foot areas totaling an area no more than 12 ft.×8 ft., the rectangular area of fluid distribution having a total fluid density of at least 60 gpm/sq. ft., the rectangular area including a first zone of fluid distribution of a 4 ft.×4 ft. area.

A fire exposure protection sprinkler assembly provides fire exposure protection for one or more windows and includes a fire exposure protection sprinkler, a sealing assembly configured to unseal in response to a fire such that fire exposure protection fluid may flow from the fire exposure protection sprinkler, and a housing having a pair of legs, with each of the legs having an aperture. The assembly also includes a deflection assembly configured to extend from the housing due to gravity and activation of a cover plate, with a deflector configured to disperse the fire exposure protection fluid over the one or more windows so as to wet the one or more windows.

A sensor-cleaning apparatus includes an upper piece, a lower piece fixed to the upper piece, a plurality of inserts inserted into the upper piece, and a plurality of nozzles. The upper piece and the lower piece form a tubular segment that is elongated along an arc of circle and encloses a chamber. Each nozzle is formed of the upper piece and one of the inserts. Each nozzle includes a deflection surface and a tunnel from the chamber to the deflection surface, and each tunnel is partially formed of the upper piece and partially formed of the respective insert.

The invention pertains generally to removable spray tip nozzles that change the direction of the aerosol path from collinear with the nozzle tip body to non-collinear with the nozzle tip body.

An agent delivery device comprises: one or more agent containers at a proximal end of the agent delivery device, wherein the one or more agent containers are configured to contain one or more fluids; an insertion section comprising a tube defining one or more lumens, the insertion section coupled to the agent containers such that the one or more fluids may flow from the agent containers to the one or more lumens and out of one or more outlets of the one or more lumens; and a distal impingement structure at the distal end of the insertion section, the distal impingement structure comprising an impingement surface arranged relative to one or more outlets to impinge the one or more fluids dispensed from the one or more outlets to cause mixing of the one or more fluids for application of the fluids at a treatment site.

A combustion system for an internal combustion engine includes a cylinder wall; a cylinder head disposed at an end of the cylinder wall, an internal surface of the cylinder wall and the cylinder head defining a combustion chamber; a fuel injector having a discharge nozzle disposed within the combustion chamber and configured to discharge a fuel jet along a fuel jet axis; and a bluff body disposed within the combustion chamber, the fuel jet axis intersecting an exterior surface of the bluff body. The exterior surface defines a first aperture and a second aperture therethrough, and an interior surface of the bluff body defines a first flow passage extending from the first aperture to the second aperture. The first aperture faces away from the fuel jet axis and the second aperture faces away from the fuel injector along the fuel jet axis.
