A nozzle includes a back plate having a first inlet passage and a first discharge opening at one end of the first inlet passage, a front plate and a plurality of nozzle plates secured between the back plate and the front plate. The plurality of nozzle plates includes a first plenum plate, a second plenum plate and a discharge plate. The first plenum plate has a first plenum, the second plenum plate has a second plenum and a second plenum projection extending into the second plenum, and the discharge plate is disposed between the first plenum plate and the second plenum plate and has one or more orifices. The first plenum is disposed in fluid communication with the first inlet passage and is configured to receive a first fluid from the first inlet passage via the first discharge opening. The one or more orifices are disposed in fluid communication with the first plenum and are configured to receive the first fluid from the first plenum. The one or more orifices each include an orifice opening at an edge of the discharge plate configured to discharge the first fluid.

Nozzle for discharging one or more fluids

A nozzle arrangement for applying fluids to a substrate has a main body which is able to be connected to a mounting region of a distributor and which has an end-side side surface. At least one first outlet nozzle for the fluid to be applied to the substrate is provided in or on the end-side side surface of the main body. A first fluid channel system is formed in the main body, via which the at least one first outlet nozzle is connected in terms of flow to a first fluid connector, which is provided in the main body of the nozzle arrangement. The nozzle arrangement is a monolithic component produced by an additive production method.

Nozzle arrangement for applying fluids, and method for producing a main body of such a nozzle arrangement

A nozzle arrangement for applying fluids to a substrate has a connection body that is connectable to a distributor mounting region and has a spray nozzle that is connectable to the connection body. The spray nozzle has a nozzle body that longitudinally extends and has a first fluid channel for the fluid to be applied to the substrate. The spray nozzle has a nozzle housing in which the nozzle body is received. Second fluid channels for shaping air are formed between a lateral surface and inner of the nozzle body. The second fluid channels extend in the direction of a nozzle outlet opening of the nozzle body such that, by way of the shaping air dispensed from the second fluid channels at the nozzle outlet region, a spiral-shaped deflection of the fluid dispensed from the nozzle outlet opening of the nozzle body is created.

Nozzle arrangement for applying fluids, use of the nozzle arrangement, and system for applying fluids

An apparatus for the intermittent application of a liquid to pasty medium onto an application surface, comprising an application valve which can be switched between an open and a closed state and is intended for dispensing the medium onto the application surface, a volumetric delivery pump for metering a volume of the medium to be passed on to the application valve, and a drive for operating the volumetric delivery pump is, inter alia, described and illustrated. The characteristic feature consists in that the apparatus has an electronic controller which, in each case cyclically, activates the drive and the application valve in dependence on each other.
