Abstract: A nozzle arrangement (1) for a high-pressure cleaning or conditioning device of a paper machine having a nozzle body (2), with a first jet channel (3) for liquids impinged with high pressure passing therethrough, with at least one partially penetrating nozzle element (4) being arranged in the jet channel (3), which forms the liquid passing the jet channel (3) into a laminar jet (5). In order to provide a nozzle arrangement (1) increasing the efficiency of the spray tube with a good cleaning result and simultaneously reduced water consumption it is provided that at least one additional nozzle element (4) is located at the nozzle body, which is arranged in another jet channel (3) different from the first jet channel (3) or together with the first and/or another nozzle element (4) in a joint jet channel (3) and that the nozzle body (2) is arranged at the nozzle arrangement (1) rotational about its longitudinal axis without being off-set axially.

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).

Abstract: The invention relates to a nozzle device for use in a paper machine, board machine, pulp dewatering machine etc., comprising a cylindrical body having an outer thread and an inner hexagon socket; a sealing element, and a nozzle insert having a cylindrical passage. The cylindrical body, the sealing element and the nozzle insert are preferably formed as a single part.
