the fluid a number of individual nozzle assemblies can also be provided adjacent to each other for establishing a nozzle system not shown fig1 shows a schematic view of a nozzle in which all of the nozzle parts are provided with two channels for guiding the fluid flow the first 1 and second 4 members as well as channel spacer 2 are shown with two channels however the channels can also be provided in only one of the first and second members and in the channel spacer or in both the first and second members without using a channel spacer fig1 a and 11 b shows a schematic view of channel spacer 2 similar to the one shown in fig2 the channel spacer 2 is designed so that the two fluid streams flowing through the channels 10 impinge closer to the openings of channels 10 this is provided by decreasing the distance 5 between the openings of the channels 10 when compared to e g the embodiment shown in fig1 in the embodiment shown in fig1 the distance 5 has been decreased so much that openings are situated in close proximity to each other and only divided by an edge shaped wall end 12 and is provided by arranging the flow channels 10 as two channels intersecting at the level of end surface 20 of the channel spacer 2 u2014 and thereby the level of the nozzle u2014 as shown in fig1 a and 11 b the embodiment of fig1 is particular useful in case atomization results in a spray of droplets in a direction towards and or sideways of the nozzle i e when.
