Definitions

  • the invention relates to a rotor nozzle for a high-pressure cleaning device with a housing, which is provided in an end wall with a pan-shaped bearing for the front spherical end of a nozzle body having a through bore, with a tangentially opening into the housing inlet for a liquid through which the liquid in Housing can be set in rotation about the longitudinal axis of the housing, so that the nozzle body rotates together with the rotating liquid and thereby lies against the inner wall of the housing with a contact surface on its periphery, the longitudinal axis of the nozzle body being inclined relative to the longitudinal axis of the housing.
  • Such a rotor nozzle is known for example from German patent DE-C-40 13 446.
  • Such a rotor nozzle has a particularly simple construction, since the nozzle body is only supported on one side, and otherwise but moved freely in the housing, on the one hand revolving on a conical jacket around the longitudinal axis of the housing, while on the other hand it rotates about its own longitudinal axis.
  • This rotary movement about its own longitudinal axis can be largely reduced by providing increased friction in the area of the contact surface.
  • this does not succeed in reducing the rotational frequency of the nozzle body in the housing.
  • a rotor nozzle of the type described in the introduction in that Nozzle body at its rear end facing away from the front, spherical end, a brake body is displaceably mounted in the longitudinal direction of the nozzle body and that in the housing the front end adjacent to the rear end of the nozzle body is arranged a contact surface on which the brake body mounted in the nozzle body abuts above the end of the nozzle body above as soon as the nozzle body rotates in the housing.
  • a brake body is therefore mounted in the nozzle body, which can move in the direction of the longitudinal axis of the nozzle body. Since this longitudinal axis is inclined to the longitudinal axis of the housing and thus to the rotating axis during the orbital movement of the nozzle body in the housing, the centrifugal force also results in a component displacing the brake body in the direction of the longitudinal axis of the nozzle body, which presses the brake body out of the nozzle body against the end-face contact surface.
  • This system results in an effective braking force which limits the rotational frequency of the nozzle body in the housing, this speed limitation working irrespective of which position the nozzle body occupies about its longitudinal axis.
  • the nozzle body can therefore rotate freely about its longitudinal axis, and yet the rotational frequency of the nozzle body in the housing is effectively limited.
  • the braking forces increase with increasing circulation frequency.
  • the contact surface for the brake body can be designed as an annular surface which is arranged in the contact region of the brake body perpendicular to the longitudinal axis of the nozzle body. Overall, the contact surface thus has a slight taper due to the inclination of the longitudinal axis of the nozzle body relative to the longitudinal axis of the housing.
  • the contact surface can carry a central projection which projects into the interior of the housing via the rear end of the nozzle body supported in the pan-shaped bearing. This ensures that even before the nozzle body is started up, it does not align itself centrally in the housing, but maintains an inclination with respect to the longitudinal axis of the housing. At the start of operation, the nozzle body is therefore immediately effectively pressed against the inner surface of the housing.
  • the inner wall of the housing runs parallel to the longitudinal axis of the nozzle body abutting the inner wall and carries the nozzle length bearing surface with the same outer diameters.
  • the rotor nozzle shown in the drawing comprises a housing 1 with a rear half 2, which is cup-shaped and has a central opening 4 in its bottom 3. At this opening 4, a connection piece 5 is formed on the underside of the bottom 3, by means of which the housing 1 can be screwed, for example, onto the end of a jet pipe of a high-pressure cleaner.
  • a front half 6 is screwed into the rear half 2 of the housing 1 by means of an O-ring seal 7 is sealed against the first half 2.
  • the second half 6 is essentially frustoconical and ends at its narrow end in an end wall 9 provided with a central opening 8, in which a pan-shaped bearing 10 surrounding the opening 8 is held.
  • the spherical front end 11 of a nozzle body 12 is supported, which essentially comprises a nozzle 13 and an adjoining hollow cylinder 14.
  • the nozzle 13 is firmly inserted into one end of the hollow cylinder 14, the interior of the hollow cylinder 14 communicates with a nozzle bore in the nozzle 13.
  • Windows 15 are arranged in the side wall of the hollow cylinder 14 and establish a flow connection between the interior of the hollow cylinder 14 on the one hand and the interior of the housing 1 on the other.
  • the hollow cylinder 14 has a somewhat larger diameter than in the rest of the region and here forms a receiving bore 17 for a spherical brake body 18 which is free in the receiving bore 17 parallel to the longitudinal axis of the nozzle body 12 is guided.
  • the hollow cylinder 14 On the outside, the hollow cylinder 14 carries two O-rings 19 and 20 at an axial distance from one another in the area surrounding the receiving bore 17, both of which abut the inner wall 21 of the second half 6 of the housing 1.
  • This inner wall 21 runs parallel to the longitudinal axis of the nozzle body 12 applied to the inner wall, so that both O-rings 19 and 20, which are arranged on the cylindrical outer wall of the hollow cylinder 14, are pressed onto the inner wall 21 with the same force.
  • the insert 22 On the side facing the housing interior, the insert 22 has a projection 26 projecting centrally into the housing interior, which protrudes beyond the rear end 16 of the nozzle body 12 and thus prevents the nozzle body from being able to align itself centrally in the housing 1.
  • high-pressure cleaning fluid is introduced via the connecting piece 5 and the opening 4 in the distributor space 24 and from there passes through the bores 25 into the interior of the housing 1. This results in a fluid filling rotating about the longitudinal axis of the housing in this interior .
  • the increased forces with which the two O-rings 29 and 20 are pressed against the inner wall of the front half 6 of the housing 1 act in the same direction. Since the distances to be covered by each of the two O-rings during a revolution in the housing along the conical inner wall are different, a slip occurs between the O-rings 19 and 20 on the one hand and the inner wall on the other hand, which also limits the rotational frequency. This effect is increased by the increase in the contact forces with which the O-rings 19 and 20 are pressed against the inner wall as the speed increases under the influence of the brake body 18.
