<p>Arrangement for controlling of a cleaning nozzle (1) showing nozzle openings intended for cleaning of pipe lines and which is connected with a source of pressure medium via a supply conduit (2). The nozzle openings partly show a first outflow direction and a second outflow direction in relation to the supply conduit (2) at opposite sides of the nozzle, the two directions both being directed backwards respectively forwards from the cleaning nozzle (1). The angle between the first outflow direction of the nozzle openings and the longitudinal direction of the supply conduit (2) at the inner wall is smaller than the angle between the second outflow direction and the longitudinal direction of the supply conduit (2) at the opposite side of the nozzle.</p> |
