FLAT JET PATTERN

In a flat jet spray the liquid droplets produce a flat liquid layer. It is possible to produce different liquid thicknesses depending on the nozzle design.

The vast majority of flat spray nozzles used in industry work according to one of the following principles.

IN LINE FLAT JET (PRESSURE NOZZLE)

This is the general-purpose flat jet nozzle, where the liquid enters the nozzle in line with its axis and is fed to a pressure chamber, from where it is ejected through the nozzle orifice.
Flow values and spray angles are determined respectively from the orifice cross section and the orifice profile.

IN LINE STRAIGHT JET (PRESSURE NOZZLE)

These nozzles can be considered a special kind of flat jet nozzles, with naught degree spray angle.
They produce a sharp stable, stream with a powerful impact.

SPOON FLAT JET (IMPACT NOZZLE)

In this type of nozzle the liquid is fed under pressure to a round outlet orifice, and then impacts onto a smooth surface (spoon) so to assume a flat jet shape.
This sophisticated design is an advantage since it offers a stronger jet impact using the same feed pressure.
