Abstract

A nozzle arrangement (1) for detachable arrangement in an outlet of a tubular nozzle fitting, which is allocated to a high-pressure cleaning or conditioning device of a paper machine, having a rotationally-symmetric nozzle body (2), including a carrier (3) formed as a circular disk with a central recess (5) encompassed thereby and a dome (6) bulging with its wall over the recess (5) at a flat side (4) of the carrier (3), and with a first jet channel (7) penetrating the wall, in which at least one first nozzle element (8) is arranged, which forms the liquid passing the jet channel (7) into a laminar jet. The carrier (3) of the nozzle body (2) has an exterior contour with a constant curvature or one changing in reference to the rotational symmetry axis of the nozzle body (2). In order to provide a nozzle arrangement (1), which is easily produced and improves the cleaning and/or conditioning performance of the allocated nozzle fitting and/or spray tube, and here consumes as little amount of water for cleaning and provides higher flexibility during the cleaning process, the nozzle body (2), in its first jet channel (7) includes at least a second nozzle element (8) or the nozzle body (2) has at least another jet channel (7) penetrating the wall of the dome (6) with at least a second nozzle element (8), each forming a laminar jet, which together with the first jet passes the recess (5) of the carrier (3) and at least the carrier (3) of the nozzle body (2) has a multiple rotational symmetry and the dome (6) has a rotational symmetry of the same or different number as the carrier (3) or is embodied rotationally symmetrical in reference to the rotational axis of the nozzle body (2).
