Abstract:
A head includes an outer cylindrical body with at least one upper inlet for fluids, at least one outlet side nozzle and at least one helical duct having a helical central line. The duct connects the upper inlet to the nozzle and imparts the fluid flowing through it a helical motion about the longitudinal axis of the outer body towards the nozzle. The helical duct is progressively tapered towards the nozzle and includes a terminal length of the duct which is radiused to the nozzle in a tapered manner, both when viewed in cross-sectional planes parallel to the longitudinal axis and tangent to the helical central line, as well as when viewed in cross-sectional planes perpendicular to the longitudinal axis.
