An inductive electrostatic atomization nozzle includes a nozzle body. The nozzle body has an internal gas flow channel and a liquid flow channel surrounding the internal gas flow channel. An electrode ring is arranged around the liquid flow channel at an inlet of the liquid flow channel. In the inductive electrostatic atomization nozzle, the electrode ring is arranged at the inlet of the liquid flow channel, which ensures that the electrode ring is located far away from the outlet of the inductive electrostatic atomization nozzle.

A fluid atomizer comprising a body having a front surface, a rear surface and a body axis extending from the front to rear surfaces. The body comprises a first fluid outlet disposed in the front surface of the body, a first fluid inlet, and a first fluid passageway connecting the first fluid inlet with the first fluid outlet. The first fluid outlet defines an arcuate slit. The body further comprises a second fluid outlet disposed in the front surface of the body, a second fluid inlet, and a second fluid passageway connecting the second fluid inlet with the second fluid outlet. A shelf having an attraction surface protrudes from the front surface of the body. The second fluid outlet is located between the first fluid outlet and the shelf. The atomizer can be used in apparatus and methods utilizing atomized fluid.

A battery-powered liquid pump air-assist misting sprayer that includes an air outlet ducting system that significantly improves both the ergonomic target focus and the pattern orientation efficiency, especially as when spraying insecticides along bushes and trees.

A spray gun includes first and second air outlet channel arrangements. At least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the first arrangement and at least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the second arrangement can be controlled independently of one another in an open and/or closed loop manner. The spray gun also includes a third air outlet channel arrangement and at least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the third arrangement can be controlled in an open and/or closed loop manner independently of at least one parameter of the first arrangement, and/or independently of at least one parameter of the second arrangement. Thus, three different types of air (atomisation, shaping, and transporting) can each be controlled independently providing increased flexibility in use for different painting tasks.

Various embodiments concern a sprayer having a blower that outputs a HVLP flow of air into a hose, the hose connecting with a spray gun. A pressure sensor measures pressure of the HVLP air within the hose via a tube that branches from a fitting to which the hose connects. If the sensor indicates that the pressure level has increased above a threshold amount, indicating that the trigger of the spray gun is not being actuated, then power output to the blower is reduced (e.g., stopped). HVLP air is trapped within the hose by two valves when the trigger is not actuated. When the sensor indicates that the pressure level has decreased, corresponding to release of the trapped HVLP air into the gun for spraying by actuation of the trigger, power to the blower is increased (e.g., resumed).

An object of the present invention is to provide a spray device that can separately apply a coating liquid, and can form a dense organic substance film having high uniformity, and a spray coating method. To achieve the object, the spray device includes: a spray; an air flow forming unit that forms an air flow for restricting a flying space of a coating liquid sprayed by the spray; and a space heating unit that heats the flying space of the coating liquid from outside of the air flow formed by the air flow forming unit.

The present invention generally relates to an atmospheric spray process for producing a controlled conical shrouded oxygen gas stream designed to intercept a plasma effluent stream to inject and mix oxygen with powder particles contained in the plasma effluent prior to the molten power particles entrained in the plasma effluent solidifying on a substrate.

A set of nozzles for a spray gun, especially a compressed-air paint spray gun, comprises at least one nozzle module group with at least two different nozzle modules for mounting in or on the same base module of a spray gun. The nozzle modules have different medium flow rates under the same spray conditions, the spray jets generated by the nozzle modules having substantially the same spray jet section height and the same spray jet section width, the spray jet sections of the different nozzle modules in particular being congruent. A spray gun system, a method for embodying a nozzle module, a method for selecting a nozzle module from a set of nozzles for a paint job, a selection system, in particular a “slide gate system”, and a computer program product are also disclosed. The user can select the nozzle module which is ideal for the paint job and mode of operation in question.

An electrostatic spray chilling system is configured to rapidly cool foodstuffs. A conveyor traverses foodstuffs through a chilling tunnel. A chilled primary airflow is provided to the chilling tunnel to cool the foodstuffs. As the foodstuff is traversed through the chilling tunnel, spray modules generate and apply sprays of electrostatically charged fluid onto the foodstuff. The charged fluid droplets are attracted to the grounded foodstuff. The charged fluid droplets can be guided onto the foodstuff by secondary fans, configured to generate subflows of the chilled primary air, and by air guiding baffles.

A method of painting a vehicle according to an embodiment including a first member and a second member which includes a painting surface and which is made of a material different from that of the first member. The method includes acquiring an environmental condition and a painting condition when the first member has been painted, and determining an environmental condition and a painting condition for the second member, which are determined in advance so that a color of the second member and a color of the first member will have a sameness in view of the acquired environmental condition and painting condition for the first member, as the environmental condition and the painting condition at the time of painting the second member which may be used together with the first member.
