The disclosure relates to an applicator (RZ), in particular a rotary atomizer, for the application of a coating agent, in particular a two-component paint, comprising a first coating agent connection (SL) for feeding a first coating agent, in particular a basic resin of a two-component paint, a first coating agent strand (L1-L4), which extends in the applicator (RZ) from the first coating agent connection (SL) and carries the first coating agent, and a first valve (SLV1), which is arranged in the first coating agent strand (L1-L4) and controls the flow of the first coating agent, wherein the first valve (SLV1) can be controlled by a first control signal. It is proposed that a first pressure-relief valve (SLV1), which is actuated by its own medium, is arranged in the first coating agent strand (L1-L4) and, to avoid a problem being caused by excessive pressure, opens automatically when the pressure upstream of the first pressure-relief valve (SLV1) exceeds a certain maximum pressure.

The invention provides apparatus for spray coating of substrates using a rotary bell cup atomizer equipped with an air-driven main turbine and a supply of pressurized primary shaping air conveyed through primary shaping air channels and nozzles for controlling the shape of the atomized spray pattern exiting the bell cup edge, the apparatus further including an auxiliary, independently air-driven turbine equipped with a rotatable vortex generator, and including a separate air supply of secondary shaping air for supplying secondary shaping air through secondary air channels and nozzles to further control the shape of the atomized spray pattern exiting the bell cup, which secondary shaping air, on passing through the vortex generator, produces a curtain of shaping air in a vortex-like pattern, which, in conjunction with and mixing with the primary shaping air from the primary air nozzles, produces improved pattern control, transfer efficiency and quality of coating on the substrate.

A seed coating assembly (16) includes a housing (36) with a high-speed rotary coating atomizer (66) therein, and a relatively slow speed rotatable body (42) equipped with through-slots (44) located above the atomizer (66) in a location to divert and evenly spread incoming seeds prior to coating thereof. The body (42) is preferably a substantially circular disk mounted coaxially with the atomizer (66) at a distance of from about 1.5-10 inches above the atomizer (66).

A control system for devices driven by or utilizing decompressing air is provided. The system includes a supply of compressed air connected to a compressed air-utilizing device. A source of heated fluid is provided and is connected to a heat exchanger that transfers heat from the heated fluid to the compressed air. The compressed air is heated in the heat exchanger sufficiently that upon decompression the temperature of the device is not lowered to the ambient dew point. The system is particularly applicable to devices utilizing compressed air for the spraying of liquid materials

A coating device includes: a rotating shaft; outer members; and an inner member connected to at least one of the outer members. The inner member includes: a cylindrical body which is connected to at least one of the outer member and includes an annular opening continuing to a coating-material diffusion surface of the outer member; a disk-shaped lid which is provided on the inner side of the opening and has an outer peripheral edge part of a smaller diameter than the opening; and a supporting part which connects the lid and the body. A rear surface of the lid and an inner peripheral surface of the body form a coating-material reservoir. An annular slit is formed between the outer peripheral edge part of the lid and the opening. The supporting part is provided more inside in the radial direction than the slit when viewed along an axial line.

The present application is related to reducing the paint left inside the piping of the painting device. More specifically the present application is directed to a painting device that includes: a paint output part for outputting paint towards an object to be painted; a paint piping for the paint to pass through towards the paint output part; and a steel ball provided inside the paint piping; and a paint supply part supplying the paint to the paint piping from a side opposite to the paint output part. After the paint supply part stops supplying of the paint, the steel ball moves inside the paint piping towards the paint output part while the paint output part outputs the paint towards the object to be painted. The first moving fluid causes the steel ball to move inside the paint piping towards the paint output part by pushing the steel ball.

A multi-disk spinning disk assembly for atomization and encapsulation applications. A number of patterned disks are stacked to form a disk stack having a feed well in the center core of the stack. Each patterned disk has channels defined by spacers, with the channels and spacers being of varying depths, heights, and/or widths. The fluid to be atomized or encapsulated is delivered to the feed well. The fluid then flows into the channels, which communicate the fluid toward the outer edges of the disks. The fluid exits the disk stack from a circumferential gap, which is created by interposing spacing disks between the patterned disks.

An atomizing disc, an atomizing device with the atomizing disc, and an unmanned aerial vehicle are provided. The atomizing disc includes: a bottom disc, an upper surface of the bottom disc being provided with a liquid inlet space; and a plurality of ribs, the plurality of ribs being disposed on the upper surface of the bottom disc and being spaced apart in a circumferential direction of the bottom disc. A centrifugal flow passage in communication with the liquid inlet space is defined between two adjacent ribs and the bottom disc. An end of a rib close to an edge of the bottom disc is provided with a first groove penetrating a side portion of the rib so as to cut fluid flowing through the centrifugal flow passage.

A rotary atomiser bell cup comprising a bell portion 5 for spraying media in use and a hub portion 6 via which the bell portion 5 is rotatingly drivable in use, wherein the hub portion 6 is a machined metal portion and the bell portion 5 has been built up on the hub using an additive manufacturing process.

Paint supply channel from paint chamber to rotary atomizing head of cartridge that forms the paint supply source is provided with first shearing member or second shearing member as a paint micronization means in order to promote micronization of the paint sprayed from rotary atomizing head. This first shearing member and second shearing member are equipped with a plurality of micropores for which the total area of the part that permits the distribution of paint is 1.53 mm.sup.2 or less.
