ROTARY NOZZLE FOR A HIGH-PRESSURE CLEANING DEVICE

摘要

Disclosed is a rotary nozzle (10) for a high-pressure cleaning device, comprising a housing (12) that has at least one tangentially extending inlet (18) and an outlet (22) which is located on an end wall (24) and on which a pot-shaped, centrally open depression (30) is located, and comprising a nozzle member (62) which is disposed in the housing (12) and has a continuous duct (72) and a spherical end (64) of which is supported in the pot-shaped depression (30); the nozzle member (62) is made to rotate about the longitudinal axis (26) of the housing (12) by the liquid flowing through the housing (12); the rotary nozzle (10) further comprises an insertion piece (46) that can be inserted into the housing (12), is supported on the wall of the housing (12), and forms a plurality of flow resistance elements (50) which are spread across the circumferential direction of the insertion piece (46). In order to further develop the rotary nozzle (10) in such a way as to make it less sensitive to pressure variations of the liquid and increase its service life, the insertion piece (46) can be connected to the housing (12) so as to rotate therewith and be axially immobile.
