A method for emitting a fluid from an aerial fluid dispersal system includes emitting the fluid from a plurality of individually controlled nozzle assemblies distributed across a manifold assembly. The method also includes receiving, at a controller, an input associated with a desired droplet size of the fluid emitted from each respective nozzle assembly and determining, by the controller, a target differential fluid velocity for each respective nozzle assembly based on the desired droplet size. The method also includes regulating, using the controller, the velocity of the fluid exiting each respective nozzle assembly to produce the target differential fluid velocity from each respective nozzle assembly.

A liquid material discharge device includes a discharge member made of a rod-shaped body, a liquid chamber which is wider than the discharge member and in which a tip portion of the discharge member is disposed, a discharge port in communication with the liquid chamber, a liquid feed path establishing communication between the liquid chamber and a liquid material storage container, a drive device driving the discharge member, and a main body. The liquid material discharge device further includes an elongate insert member that is removably inserted into the liquid feed path without cutting the communication between the liquid chamber and the liquid material storage container.

The invention relates to a metering system (1) for a metering substance, comprising a nozzle (40), a feed channel (44) for the metering substance, a discharge element (31), and a piezo actuator (61) which is coupled to the discharge element (31) and/or the nozzle (40). The piezo actuator (61) of the metering system (1) is hermetically encapsulated in a housing (62).

A system and composition for imprinting and removing high resolution images onto natural or artificial lawns and fields, covered areas such as sports fields, and landscapes, using a foaming carrier composition which enhances the functional performance of liquids containing special active agents to accomplish specific tasks such as marking and painting. The foaming carrier composition can be a solution of one or more active agents for painting, cleaning, lubricating, fertilizing, and effervescing various surfaces including athletic fields.

The invention relates to a nozzle arrangement for atomizing a fluid flow, which is supplied under pressure, into fine particles, which has: a conical element with an upper surface, a lower surface and an outer surface which is adjacent to the upper and the lower surface, wherein the outer surface has a multiplicity of grooves which are formed therein and extend between the lower surface and the upper surface; and a counter element which is provided with a recess and is designed to receive the conical element and which has an inner surface such that the grooves are at least partially covered by the inner surface in order to form a multiplicity of channels; wherein the channels define outputs in order to let out a respective fluid jet which strikes against at least one other fluid jet in a region spaced apart from the upper surface of the conical element in order thus to atomize the fluid flow, and wherein the conical element is movable along the axis in order to increase or to reduce the effective cross section of the nozzle arrangement.

A sprayer system having dynamic pre-sets to control spray nozzles that each individually operates continuously or under a time-modulated or a frequency-modulated electronic signal control to release liquid droplets. Collectively, adjacent or near neighboring nozzles are also controlled by time-sequencing through different modes of operation or physical configurations on each spray nozzle. The spray nozzles are mounted on a variety of implements including agricultural or industrial spray booms.

A spray boom includes a body having a length defined a first end and a second end thereof. The body is formed by a plurality of layers of composite material adapted to be molded together to form an inner surface and an outer surface. A hollow cavity is defined in the body internally of the inner surface, and a channel is formed in the body between the inner surface and the outer surface. The channel extends along the length and is defined between the first end and the second end.

A disclosed piping manifold for providing pulsating flow includes an outer tubular member extending along a longitudinal axis. The outer tubular member includes a plurality of outer radial openings. An inner tubular member is positionable within the outer tubular member and rotatable about the longitudinal axis. The inner tubular member includes a plurality of inner radial openings, an inlet port configured to receive a fluid, and a lumen providing a fluidic pathway between the plurality of inner radial openings and the inlet port. Rotation of the inner tubular member about the longitudinal axis is configured to periodically bring the plurality of inner radial openings in and out of registration with the plurality of outer radial openings to provide a plurality of pulsating flows of the fluid out of the outer radial openings.

Embodiments include individual physical spray nozzles that have passageways inside to combine fluids that flow out of the spray nozzles. The nozzles have at least two valves that are opened and closed in an interleaved manner. The nozzles have multiple outlets. Such nozzles are mounted on a variety of implements including agricultural or industrial spray booms.

An applicator for a coating product comprising printing nozzles, each including an outlet channel emerging in the downstream direction by a coating product discharge orifice. The printing nozzles are distributed on at least two faces of a body of the applicator and the discharge orifices of these nozzles extend along at least two nonparallel planes.
