A nozzle for a member of a fuel combustion system of an engine includes a hollow nozzle body. The nozzle body includes an outer surface, an inner surface, and an orifice surface. The outer surface defines an outer opening. The inner surface defines an interior chamber and an inner opening. The orifice surface defines an orifice passage extending between, and in communication with, the outer opening and the inner opening. The orifice passage is in communication with the interior chamber via the inner opening. The orifice surface includes a boundary surface and a protrusion. The protrusion projects from the boundary surface radially inwardly into the orifice passage.

An adjustable arc irrigation spray nozzle can include one or more features including a dual orifice, a multi-trajectory ramp, radial ribs, an impedance wall, and/or a variable orifice.

A method of protecting an occupancy, using a pendent fire protection sprinkler arrangement to be mounted in a ceiling, includes providing a plurality of pendent fire protection sprinklers, each having a sprinkler body having an inlet and an outlet defining a fluid passage and a sprinkler axis, and threads for connection to system piping of the occupancy. A pair of frame arms projects downwardly from the outlet and meet to form a junction. A plug seals a fluid passage, and a thermally responsive element between the plug and the junction retains the plug in the fluid passage. A deflector is mounted to the junction and includes a planar central portion extending outwardly from the sprinkler axis along a plane perpendicular to the sprinkler axis and first, second, third, and fourth angled portions bent away from the frame arms in the outlet direction from the plane of the planar central portion.

A fire protection nozzle includes (A) a body having a flow passage for a fluid that flows through the body in an output direction, frame arms having proximal ends connected to an outlet orifice and distal ends, the frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms at a distance from the outlet orifice, the junction including a central bore and an outer wall, and (B) a planar member deflector configured to be mounted to the body. The deflector includes a planar member having a plurality of slots on a periphery of the planar member that define a plurality of tines. The plurality of slots include at least first slots, second slots, third slots, and fourth slots.

A smoke generator for anti-burglar purposes includes a canister holding means for holding a canister for chemicals to be used to generate smoke wherein the smoke generator further includes a smoke deflector arranged below the position of the canister for even distribution of generated smoke, and wherein the smoke deflector have a smoke deflector cavity of sector shape. The smoke generator is provided with a cartridge for the canister to ease replacement of used or expired canister. The smoke deflector is provided with a residual collector to prevent residuals and debris from littering the room where the smoke generator is used.

Embodiments herein describe a portable device for administering a physiologically active liquid that includes a container for holding the liquid, a pressure system for applying pressure to the liquid, an atomizer for atomizing the liquid, and an applicator for administering atomized liquid. The atomizer includes at least one nozzle through which liquid can be ejected from the container and an impact element on the nozzle outlet side that is functionally combined with the nozzle. Moreover, the atomizer is configured in such a way that, in a pressure range that can be generated with the pressurizing system, liquid emerging from the nozzle breaks up into droplets prior to striking the impact element.

A fluid flow actuated tool including a housing, a tool and an actuating mechanism. The housing includes a housing interior. The housing interior receives a flow of fluid. The actuating mechanism includes a fluid wheel structure. The fluid wheel structure is connected to the tool. At least a portion of the fluid wheel structure is arranged in the flow of fluid for rotating the fluid wheel structure. The tool is actuated based on rotation of the fluid wheel structure.

Spraying apparatus enabling large-volume generation of particles minute to a Brownian-motion engendering level. An atomization tank stores liquid formulation; an in-tank arrangement of ultrasonic vibration elements atomizes the liquid formulation to generate fine particles; a blower having a blower element for maintaining predetermined rpm blasts into the atomization tank interior through a top-panel blow port conveyance air conveying the fine particles; and a send-out port on the tank releases the fine particles together with the conveyance air. An in-tank baffle plate, situated above the ultrasonic vibration elements and underneath the blow port, is oriented to block liquid columns produced by the ultrasonic vibration elements, and conveyance air supplied through the blow port.

An ablutionary fitting includes an outlet for providing a stream of water and a dispersing barrier arranged in the stream, such that the liquid passing through the dispersing barrier is broken up into a plurality of smaller streams, forming a spray, wherein the smaller streams are at least in part directed by the dispersing barrier.

A pendent fire protection sprinkler includes a sprinkler body having an inlet and an outlet that define a fluid passage and a sprinkler axis, a pair of frame arms that form a junction, a plug that seals the fluid passage, and a thermally responsive element provided between the plug and the junction, and configured to maintain the plug in the fluid passage prior to actuation of the sprinkler. A deflector, mounted to the junction, includes an annular, planar central portion extending along a plane that is perpendicular to the sprinkler axis, as well as a first angled portion, a second angled portion, a third angled portion, and a fourth angled portion, each angled portion extending outwardly from the planar central portion. Each of the first to fourth angled portions is bent away from the frame arms in the outlet direction from the plane of the planar central portion.
