The asymmetric shape may be formed by a notch or a chamfer or a stepped portion intersecting with the liquid dischargepassage, or combinations of these features, or in other manners.
The liquid dischargepassage extends along an axis and the opening is shaped asymmetrically about the axis to provide a controlled directional movement of the liquid filament in a desired direction.
