Definitions

  • the invention relates to a rotor nozzle for a high-pressure cleaning device with a housing, a rotor rotatably mounted therein and rotated by the cleaning fluid and with a nozzle arranged downstream of the rotor, the outlet axis of which includes a variable acute angle to the axis of rotation of the rotor and which is rotated by the rotor in this way whose axis of rotation is rotated so that the emerging jet of cleaning liquid rotates on a cone jacket.
  • Such a rotor nozzle is known from EP-A-0 252 261. It enables a point jet to be emitted which revolves on a cone shell, with the known rotor nozzle the angle of the cone shell being able to be expanded as a function of the speed or by adjusting a bearing socket on the rotor.
  • adjustable stops are arranged on the housing and limit the expansion of the acute angle between the outlet axis of the nozzle and the axis of rotation of the rotor differently depending on the position of the limiting elements.
  • stops By adjusting the stops, it is easily possible to limit an inclined position of the nozzle and thus an increase in the opening angle of the cone shell, the operator being able to move these stops in the housing of the rotor nozzle, so that the stops then have a differently wide inclination of the nozzle outlet axis compared to the rotor axis of rotation.
  • a rotor nozzle with a stilt which receives the nozzle and is supported with a spherical end in a pan which is open in the middle and held on the housing, while at the other end a driver connected to the rotor and arranged at a radial distance from the rotor axis engages it is particularly advantageous if the stop surrounds the stilt concentrically to the axis of rotation of the rotor, is adjustable in the direction of the axis of rotation of the rotor and forms an abutting edge on the outside of the stilt which surrounds it.
  • the stop in the housing is axially displaceable and rotatably mounted with respect to the axis of rotation of the rotor and is screwed into a threaded bore of an adjusting sleeve arranged coaxially to the axis of rotation of the rotor, which is axially immovable in the housing and freely rotatable with respect to the axis of rotation of the rotor is.
  • an adjusting sleeve arranged coaxially to the axis of rotation of the rotor, which is axially immovable in the housing and freely rotatable with respect to the axis of rotation of the rotor is.
  • the driver carries a groove running in the radial direction, into which the stilt is immersed with a driving pin.
  • the adjustment sleeve can close the front of the housing and support the pan for storing the stilts. In this way, the adjusting sleeve practically forms part of the housing, the two housing parts being rotated relative to one another about the longitudinal axis of the housing in order to achieve a change in the beam opening angle.
  • the rotor nozzle shown in Figure 1 comprises a cylindrical housing 1 which carries an internally threaded bore 2 on one side, while it is open on the opposite side.
  • the inner threaded bore 2 is followed by a bore with a smooth inner wall 4, which merges into a bearing bore 5 with a reduced inner diameter and finally opens into the cylindrical interior 6 of the housing 1, the inner diameter of which is substantially larger than the inner diameter of the bearing bore 5.
  • a hollow shaft 7 is inserted into the bearing bore 5, which is supported with an annular flange 8 on the step 9 between the inner wall 4 of the bore 2 and the bearing bore 5 and which projects into the interior 6 of the housing.
  • a rotor 10 is rotatably mounted, which has two arms 12 projecting radially from the hollow shaft 7 and reaching as far as the inner wall 11 of the interior 6.
  • the rotor 10 is secured on the hollow shaft 7 in the axial direction on the one hand by a step 13 on the outer circumference of the hollow shaft 7 and on the other hand by a screw 14 which is screwed into the free end of the hollow shaft 7 and thereby closes the end of the hollow shaft 7.
  • the hollow shaft 7 has at the height of the arms 12 of the rotor 10 wall openings 16 which connect the interior of the hollow shaft 7 with the interior 17 of the rotor 10, which again through holes 18 in the arms 12 with outlet openings 19 to the Ends of the arms 12 communicates.
  • the outlet openings point in opposite directions in the circumferential direction, so that liquid escaping through the outlet openings 19 rotates the rotor on the hollow shaft 7.
  • the liquid supply to the hollow shaft 7 takes place via a pipe piece 20 screwed into the internal threaded bore 2, which carries a coupling ring on the part emerging from the housing 1 for connection to a jet pipe of a high-pressure cleaning device (not shown in the drawing), while on the opposite side into the Hollow shaft 7 immersed.
  • the pipe section 20 is sealed by means of an annular seal 22 with respect to the smooth inner wall 4 of the bore 2, in addition, the tubular section 20 also carries a further ring seal 23 in a conically narrowing transition area 24 which, when the tubular section 20 is fully inserted into the hollow shaft 7, seals against a complementary one Sealing surface 25 rests in the entry area into the hollow shaft 7.
  • a plurality of radial openings 26 are arranged in the wall of the pipe section, which are sealed off from the inner wall of the hollow shaft 7 when the pipe section 20 is fully inserted into the hollow shaft 7, as shown in FIG. 1.
  • the pipe section 20 can be rotated in the internal threaded bore 2 with respect to the housing 1 and thereby shifted in the axial direction until the interior of the pipe section 20 is connected via the openings 26 to the annular channel 27 formed by the bore 2 and surrounding the pipe section 20, as in this is shown in the embodiment of Figure 2.
  • This ring channel 27 is connected via a series of channels 28 directly to the interior 6 of the housing 1, so that part of the liquid supplied through the pipe section 20 is bypassed on the rotor 10 is led past.
  • This bypass is formed by the openings 26 in the pipe section 20, by the ring channel 27, by the channels 28 and by the interior 6 of the housing.
  • the liquid which bypasses the rotor is combined with the liquid which has flowed through the interior of the rotor and reaches the interior 6 through the outlet openings 19.
  • a driver 29 which has a groove or opening 30 that extends radially from the center to the outside, is rotatably attached.
  • a driver pin 31 of a stilt 32 which carries a nozzle 33 with a spherical head, plunges into this groove.
  • This stilt 32 has lateral openings 34 which connect the interior 6 of the housing 1 to the nozzle opening 36 in the nozzle 33 via a central channel 35 in the stilt 32.
  • This stilt is supported with the spherical part of the nozzle 33 in a central bearing socket 37 which has a central opening 38 in alignment with the nozzle opening 36.
  • the bearing socket 37 is arranged in the end wall 39 of an adjusting sleeve 40, which plunges into the open end of the housing 1 in a sealed manner by means of an annular seal 41 and is mounted on the housing 1 so that it cannot move and rotate freely in the axial direction.
  • the housing has an annular groove 42 on its inner wall and the adjusting sleeve 40 has an annular groove 43 aligned with the annular groove 42 on its outer wall, into which a clip 44 is inserted.
  • the adjusting sleeve 40 has an internal thread 45, into which a hood-shaped stop 46 is screwed, which engages in longitudinal grooves 48 on the inner wall of the interior 6 of the housing 1 by means of laterally projecting guide projections 47 and thereby the hood-shaped stop 46 relative to the housing 1 axially displaceable, but non-rotatably.
  • the hood-shaped stop 46 When the adjusting sleeve 40 is rotated relative to the housing 1, the hood-shaped stop 46 thus screws more or less deeply into the internal thread 45, that is to say the stop 46 can also be moved between a fully screwed-in position (FIG. 1) into a position in which the rotor 10 is approximated. In this position, the hood-shaped stop 46 extends over the driver 29 of the rotor 10 (FIG. 2).
  • the stop 46 is provided with an inwardly projecting stop edge 49 which runs concentrically to the axis of rotation of the rotor and which abuts the outer wall of the stilt 32 and thus the oblique position of the stilt 32 relative to the axis of rotation of the rotor limited.
  • the stop 46 shown in FIG. 1 in which it is completely screwed into the internal thread 45, a very extensive inclination is possible, whereas in the extreme case of the stop completely unscrewed in FIG. 2, an inclination of the stilt 32 is prevented at all, so the exit axis of the nozzle practically coincides with the axis of rotation of the rotor.
  • the hood-shaped stop 46 also forms a collecting space 50 for the liquid entering the interior 6.
  • This collecting space 50 is conically narrowed in the part facing the nozzle 33, so that the liquid is supplied on the one hand to the openings 34 in the stilt 32, but on the other hand to the central opening 51, which is surrounded by the stop edge 49 and through which the stilt 32 passes through.
  • the bearing socket 37 is provided concentrically and immediately a plurality of bores 52 parallel to the axis of rotation of the rotor, which open out into radial bores 53 of the adjusting sleeve 40 leading from the outside inwards.
  • These radial bores 53 first have an enlarged outer part 54 and then an inner part 55 with a reduced cross-section, which opens into a central, funnel-shaped opening 56 in the adjusting sleeve 40, which adjoins the opening 38 of the bearing socket 37 connects.
  • the bores 53 enter the opening 56, which widens in a funnel shape, in the radial direction.
  • valve bodies 57 which are displaceable in the longitudinal direction of the bore are arranged, which are sealed with respect to the bore 53 by means of ring seals 58 and optionally close or release the bore 53 in the transition region between the outer part 54 and the inner part 55.
  • the valve bodies 57 are pressed radially outward by a coil spring 59 arranged in the outer part 54 of the bore 53 against a contact surface 60 on an adjusting ring 61, which in turn is rotatably mounted on an external thread 62 of the adjusting sleeve 40.
  • the contact surface 60 has different distances in the axial direction from the axis of rotation of the adjusting ring 61, so that when the adjusting ring 61 is rotated, the valve body 57 is pressed into the bore 53 to a different depth against the action of the helical spring 59 and the flow cross section of the bore 53 more or release less or close completely when fully inserted.
  • a partial flow can be passed directly past the nozzle 33 into the funnel-shaped opening 56, which mixes there with the point jet emerging from the nozzle opening 36.
  • this reduces the exit velocity in the point jet, since the amount of liquid becomes smaller, on the other hand, the amount of liquid entering the spot jet at the side tears open and mixes with the amount of liquid in the spot jet to form a fanned out, voluminous jet with a circular cross-section and a lower impact velocity of the liquid particles .
  • This transition can be varied continuously by adjusting the metering valves.
  • the bypass line formed by the bores 52 and 53 is open; in the exemplary embodiment in FIG. 2, however, the metering valves are shown closed.
  • the adjustment of the valve body is not over one made of the adjusting sleeve rotatable adjusting ring, but the valve body 57 are screwed into the outer part 54 of the bore 53 and rotatable directly via knurled disks 63 and adjustable to different immersion depths.
  • a rotor nozzle is obtained, which gives the possibility of steplessly adjusting the angle of the point jet emerging from the nozzle between 0 and a maximum value, for example 10 °. It is also possible to continuously adjust the speed of the jet by not directing part of the liquid through the rotor, but past the rotor. Finally, the nature of the jet itself can also be changed by dividing the liquid flow through the nozzle 33 and adding a quantity of liquid transversely to the point jet. Overall, you get a very versatile rotor nozzle, which is robust in construction and allows easy operation of the various adjustment options.
