Definitions

  • the invention relates to a rotor nozzle, in particular for a high pressure cleaning device, with a nozzle housing that at its axial one end a central inlet opening and at the other end an outlet for the Has cleaning liquid, as well as with a Nozzle housing inclined with respect to its longitudinal axis arranged, driven by rotation and on the Rolling rotor housing inner wall, which with a of the cleaning liquid flowed through, in a stilt arranged nozzle is provided, the outlet opening pointing end pivotally supported in a cup bearing is.
  • Such a rotor nozzle is, for example, in DE 44 33,646. Basically, it is for many Applications of such rotor nozzles favorable in the Rule-specific high rotation speed of the rotor to reduce what already different measures were proposed. This in turn experiences the However, the rotor nozzle is usually a limitation in that an influence on the spray pattern is not is more or hardly possible.
  • the advantage achieved by the invention is essential in that on the one hand about the storage of the Influencing the rotor on the bearing sleeve Sequence of movements of the flowing through Cleaning fluid for rotary rotor possible is, and that on the other hand on the inside of the rotor attached driving surfaces the movement of the Stilt is influenced, the movement of which is immediate for the achievable spray pattern is responsible.
  • Spray pattern can be influenced within wide limits.
  • convex surface of the ball joint either on the outside the bearing sleeve or on the rotor and accordingly the concave Surface inside either on the rotor or on the Bearing sleeve is arranged. It is further advantageous if the adjacent to the convex surface area of the bearing sleeve facing away from the outlet opening tapered.
  • the driving surface surrounds the stilt in a ring, the result is a conventional, essentially circular Spray pattern.
  • the rotor has a radial Sliding groove for the end of the nozzle facing away from the nozzle mouth Stilt has, whereby the groove walls the driving surfaces form for the stilts.
  • the sliding groove runs here related to the support of the stilt in its cup bearing expediently in the form of a circular arc under a radius that corresponds to the total length of the stilt, so that the Face of the stilts over which the cleaning liquid flows in the direction of the nozzle, always the same distance from the Bottom of the sliding groove.
  • the sliding groove can extend to the outer surface of the rotor, so that the end of the sliding groove also the inflow opening for the Cleaning liquid forms.
  • the sliding groove is one of these narrower flow groove arranged.
  • This flow groove is advantageously about arranged in the middle of the slide groove and at the ends closed. Do close to the top of the Groove walls of the sliding groove are in the sleeve-shaped area of the rotor towards conical surfaces.
  • the spray pattern can be influenced in that the bearing sleeve has two parallel delimiting surfaces, the stilt between them, which are aligned with respect to the longitudinal axis of the nozzle housing at an angle of 90 ° with respect to the sliding groove, the bearing sleeve being connected to a rotor in a rotationally locking manner.
  • These boundary surfaces only allow the stilt to perform an oscillating movement, which results in a linear spray pattern of the rotor nozzle.
  • the alignment of the sliding groove in the rotor at an angle of 90 ° with respect to these boundary surfaces ensures that the rotor can run along a conical surface despite the restriction of the stilt to a pendulum movement.
  • the rotor points in a manner known per se to its End facing away from the outlet opening into an annular groove inserted friction ring over which the rotor on the Inner wall of the nozzle housing expires. This is one of the Measures to reduce the speed is achieved.
  • the rotor nozzle shown in the drawing is used especially for use in connection with a High pressure cleaning device.
  • Rotor nozzle from a nozzle housing 1, which is axially at its one end a central inlet opening 2 and at its other end an outlet 3 for the Has cleaning liquid.
  • Within the Nozzle housing 1 is opposite its longitudinal axis provided inclined rotor 4, through which the Cleaning fluid flowing through the nozzle housing is driven by rotation and is located on the inner wall of the housing passes on.
  • the rotor 4 is provided with a stilt 5, within which a nozzle 6 is arranged, which also is flowed through by the cleaning liquid and this releases through the outlet opening 3 to the outside.
  • the nozzle 6 itself is to do so with your facing the outlet opening 3 End pivotally supported in a cup bearing 7.
  • the rotor 4 is facing towards the outlet opening 3 Side sleeve-shaped and there at the end in the kind of a ball joint mounted on a bearing sleeve 8.
  • the cup bearing 7 is in turn concentric in the Bearing sleeve 8 arranged.
  • the bearing sleeve 8 carries the convex surface of the outside Ball joint, while the rotor 4 inside has a corresponding concave surface. Likewise can however, the rotor 4 also has the convex surface on the outside have the concave surface of the bearing sleeve 8 or is directly adjacent to the nozzle housing 1. To the sequence of movements of the rotor 4 along a conical surface, the one adjacent to the convex surface tapers Region of the bearing sleeve 8 facing away from the outlet opening 3 also conical.
  • the rotor 4 has in its sleeve-shaped Area two radial inflow openings 9 through which enter the cleaning fluid and to the face the stilt 5 can flow.
  • the driving surfaces of the rotor 4 for the stilt 5 can be designed according to the desired spray pattern.
  • the rotor 4 has a radial extending sliding groove 10 for that of the nozzle mouth opposite end of the stilt 5, here the groove walls form the driving surfaces for the stilt 5.
  • the stilt 5 is still a linear movement run inside the rotor 4. This leads to the result to an elliptical or lenticular spray pattern Rotor nozzle, since the stilt 5 when the rotor 4 the full movement stroke only in one direction will participate, while in the perpendicular to this Direction over the sliding groove 10 to a certain extent dodges, so do not reach the maximum deflection becomes.
  • the sliding groove 10 runs in a circular arc under one Radius, which corresponds to the total length of the stilt 5, so that the distance between the end face of the stilt 5 and the groove bottom constant regardless of the position of the stilt 5 is.
  • the sliding groove 10 extends to the outer Shell surface of the rotor 4, so that the end of the sliding groove 10th at the same time the inflow opening 9 into the rotor 4 forms.
  • To prevent the inflow of cleaning fluid into the End face of the stilt 5 is to be further improved in the bottom of the sliding groove 10 one of them narrower than this Flow groove 11 arranged.
  • This flow groove 11 runs approximately in the middle of the sliding groove 10 and is at the end in each case closed.
  • At the top of the groove walls of the Sliding groove 10 close in the sleeve-shaped area of the rotor 4 towards conical surfaces 12, like this can be seen in Fig. 2.
  • the illustrated embodiment on the bearing sleeve 8 additionally two parallel, the stilt 5 between to provide receiving boundary surfaces 13 which with respect to the longitudinal axis 14 of the nozzle housing 1 below an angle of 90 ° with respect to the sliding groove 10 are aligned.
  • the bearing sleeve 8 is with the Rotor 4 rotatably connected, for which purpose the bearing sleeve 8 in Region of their convex surface has a locking projection 15 has, which engages in a recess of the rotor 4.
  • the two boundary surfaces 13 allow the stilt 5 only a pendulum movement, so that there is a result linear spray pattern.
  • By aligning the Sliding groove 10 opposite the boundary surfaces 13 below an angle of 90 ° ensures that the rotor 4 can nevertheless run along a conical surface.
  • Around Maintaining this angle of 90 ° is the rotational one Connection between the rotor 4 and the bearing sleeve 8 required.
  • the rotor 4 has its outlet opening 3 opposite end of a friction ring 16, which in a Ring groove is inserted.
  • the friction ring 16 runs over the Rotor 4 on the inner wall of the nozzle housing 1, whereby on the one hand, wear-free operation, on the other hand, one Reduction of the rotational speed of the rotor 4 is achieved.
  • the inlet opening 2 of the rotor nozzle has one Insert 17 on the cleaning liquid enters tangentially into the interior of the nozzle housing 1.
  • the rotor 4 is driven after Vortex chamber principle.
