Abstract

The liquid aprayer has, inside its hollow body (1) and near and opposite the injection ports (16) for the liquid, a deflector wall (A). Thus first atomisation of the liquid is effected by the impact of the liquid against the wall. The slot through which the atomised spray is finally discharged can have sharp edges, causing further atomisation along them. The sprayer discharges in the form of a two-dimensional sheet, the design giving greater homogeneity of the jet.
