Abstract

A spray nozzle arrangement is provided for high pressure cleaning apparatus with an outlet nozzle of circular cross-section. A deforming member is arranged downstream of the nozzle and comprises two swing elements having substantially planar faces. The swing elements pivot about a rotary axis perpendicular to the jet. Thus, the two faces can be inclined symmetrically relative to the jet axis so that the region of the faces remote from the outlet nozzle enter the round jet, resulting in a fan-shaped jet.
