A paint bell cup for directing a spray of paint onto a surface includes a cup body having an outer surface, an inner conical surface having a circumferential edge, and a stem extending from the outer surface. The stem includes a passage that delivers paint toward the inner conical surface. The cup body includes one or more spray control features that extend along the inner conical surface toward the circumferential edge. The one or more spray control features promote a selected uniform droplet size of the paint traveling from the stem toward the circumferential edge.

An apparatus suitable for pressurized liquid transfusion is disclosed. The apparatus includes a nozzle assembly enclosed by the combination of a casing and a check nut. The nozzle assembly includes an elastomeric ring and a nozzle received by the combination of a cap and a receptacle. The elastomeric ring surrounds the nozzle and a proper seal is created therebetween. The dimension of the internal contour of the elastomeric ring is a bit smaller than the nozzle. The elastomeric ring is stretched so as to receive the nozzle. Additional processing may be applied to the elastomeric ring to achieve a different type of proper seal. Pressurized liquid passes through the apparatus so as to be transfused. The aforementioned seal serves to avoid leakage or pressure loss at the apparatus so as to avoid undesired aerosolization effects of an aerosolizer the apparatus is installed in.

A water-fertilizer-pesticide integrated multifunctional irrigation spray head, mainly including a first spray hole, a second spray hole, a spray head cap, a spray head body, an atomization core, water passing holes, springs, cover sheets, a pipe connector, water outlet holes, a throat cavity, a chamfered groove, and a helical groove. The spray head is configured as a double-flow channel structure. The spray head body and the atomization core are provided in the spray head cap. The atomization core is provided in an inner cavity of the spray head body and is threadedly connected. The bottom of the spray head body is provided with cover sheets, each of the cover sheets is connected by a respective one of the springs. When the working pressure is a low pressure, the cover sheets are in an open state, and the liquid is sprayed by means of two flow channels.

A fire suppression apparatus is configured to spray a fire suppressant agent and includes a reservoir and a nozzle. The nozzle is fluidly coupled to the reservoir and includes an inlet aperture, an outlet aperture, a passageway, and a diverter. The passageway extends between the inlet aperture and the outlet aperture. The diverter is disposed within the passageway and includes multiple diverter passageways configured to receive the fire suppressant agent from an inner volume of the diverter and direct the fire suppressant agent towards an inner sidewall of the passageway.

An aftertreatment atomizer, according to an exemplary aspect of the present disclosure includes, among other things, a valve body providing a valve seat and including a plurality of feeding channels, a pintle configured to move between open and closed positions relative to the valve seat, and a nozzle plate including a plurality of swirling grooves Each swirling groove has a pressure swirl nozzle opening configured to eject fluid exiting a respective feeding channel into an exhaust pipe.

A showerhead engine internally swirls water within a swirling chamber. Multiple swirling chambers may be used, each separated from one another. The water is swirled angled through holes in a mid plate. As the water passes through the angled holes, it is projected out an angle. The water then contacts the swirling chamber wall and continues to follow the curvature of the wall. The curved wall paired with the angled entry causes the water to continue to swirl within the swirling chamber. The water is released out of the swirling chamber through slots, which allow the water to retain the angular velocity at a discharge angle.

A method of manufacturing an orifice is provided to make the orifice capable of spraying a very small amount of fluid in an ultra-high pressure and very low temperature environments. The method also makes it possible to provide the orifice with reduced volume and mass. More specifically, the method effectively realizes a desired hydraulic performance through a simple manufacturing method in which a part of a capillary pipe is pressed to form a channel region having a cross section close to a rectangular shape.

Summary Problem: To provide a spout apparatus in which sagging of the mesh structure portion in the flow-conditioning member due to water pressure can be suppressed even if the flow-conditioning member is formed by a fine diameter mesh structure, and the flow-conditioning member can be compactly constituted and flow velocity distribution made uniform. Solution Means: The embodiment of the invention is a spout apparatus 2, including a spout apparatus main unit 6, a flow-conditioning member 12, and a spray member 16; wherein the flow-conditioning member 12 is formed by a mesh structure in which numerous fine holes are formed, and the mesh structure is layered and formed three dimensionally, such that the mesh structure portion of at least a portion of the mesh structure extends in a direction parallel to the direction of water flowing into the flow-conditioning member.
