Problems solved by technology

[0004] If the nozzle body has a very high speed of rotation about the longitudinal axis of the housing, then it can have the result that the fluid jet escaping from the outlet is scattered and thus the cleaning effect of the fluid jet hitting the surface is reduced.

Embodiment Construction

[0038] in Figure 1 to 4 A first advantageous embodiment of the rotary nozzle according to the invention is schematically shown in, which is designated by the reference number 10 as a whole. The rotating nozzle 10 has a housing 12 with a housing bottom 14 and a housing cover 16. The bottom 14 of the housing is designed to be disk-shaped and has a plurality of tangential inlets 18 which open into the inner chamber 20 of the housing 12. The inner chamber 20 is surrounded by the housing cover 16 and gradually narrows starting from the tangential inlet 18 to the outlet 22 arranged on the end wall 24 of the housing cover 16.

[0039] Via the tangential inlet 18, a fluid under pressure can be delivered to the inner chamber 20, which rotates around the housing longitudinal axis 26 in the inner chamber 20 and can escape from the housing 12 via the outlet 22.

[0040] In the inner chamber 20, a bearing in the form of a bearing ring 28 is arranged immediately upstream of the outlet 22, whi...

Abstract

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 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 longitudinal axis (70) of the nozzle member extends at an angle from the longitudinal axis (26) of the housing (12); the nozzle member is made to rotate by the liquid flowing through the housing (12) and is supported on a bearing surface (40) while rotating; a plurality of flow resistance elements, each of which has an impact surface (52; 20), is arranged on the wall of the housing (12), downstream of the bearing surface (40). In order to be able to effectively limit the rotational speed of the nozzle member (62) without notably affecting the beginning of the rotating movement of the nozzle member (62), a guiding surface (54; 122) is located upstream of each impact surface (52; 120) in relation to the direction in which the liquid flows, the impact surface (52; 120) adjoins said guiding surface (54; 122) without interruption, and the guiding surface (54; 122) runs at an angle from the radial plane of the housing (12).

Description

Technical field [0001] The invention relates to a rotary nozzle for a high-pressure cleaning device. The rotary nozzle has a housing, and the housing has at least one inlet opening into the housing in a tangential direction and an outlet arranged on the end wall of the housing. A bearing with a pan-shaped depression through the center is arranged, the rotating nozzle also has a nozzle body, the nozzle body is arranged in the housing, has a through channel and is supported in the pan-shaped depression with a spherical end, the longitudinal axis of the nozzle body It is inclined with respect to the longitudinal axis of the housing, and is placed in a circling motion by the fluid flowing through the housing, wherein the longitudinal axis of the nozzle body surrounds the cone and the nozzle body is supported by its circumferential abutment surface On the surface, downstream of the supporting surface on the wall of the housing, a plurality of baffle elements are arranged spaced apart...
