Definitions

  • the invention relates to a rotor nozzle for a high-pressure cleaning device with a housing into which a supply line for cleaning liquid, with an outlet for the cleaning liquid, with a flowed through by the cleaning liquid, in Nozzle body arranged with a housing crowned end in a conical, pan-shaped, supports the outlet of the housing surrounding the bearing and by the flow of cleaning fluid the housing is rotated at which is the longitudinal axis of the nozzle body on a cone jacket circulates.
  • Rotor nozzles are for example from DE 40 13 446 B1 known.
  • the cone jacket is also the one it delivers and through the jet of detergent discharged from the housing guided on a cone jacket so that it is possible with such a rotor nozzle a larger To sweep the surface with a beam that itself remains compact and only a very small cross section Has.
  • a rotor nozzle is known from DE 90 04 452 U1, at which avoids the stress in the storage area should be that complicated sealing measures be made in the rotor nozzle, for example by using a rubber membrane. This leads to a very much more complicated construction, at that is still at risk of damage, if only the complicated sealing measures are not fully functional.
  • DE 36 23 368 C1 (cf. preamble of claim 1) is a generic rotor nozzle described in which also a nozzle body with dipped into a special bearing shell at one crowned end, which is inserted in the housing, also in this case is a relatively complex construction necessary.
  • the opening angle of the depression between 110 ° and 150 °, in particular between 120 ° and 140 °, preferably 130 °.
  • the spherical end of the nozzle body can be spherical be, it is then advantageous if the radius between 3 mm and 7 mm, preferably 5 mm.
  • the housing is made of plastic, in particular made of polyamide, it being advantageous if the polyamide contains a glass fiber component, for example in the order of 30%.
  • the housing has a housing foot into which the supply line opens out, and a housing hood that can be connected to it into which the outlet with the recess is incorporated.
  • a housing hood that can be connected to it into which the outlet with the recess is incorporated.
  • the nozzle body from a tubular body with a in this inserted nozzle, which is the crowned End of the nozzle body forms.
  • the nozzle body is a tubular body includes one end of which is the crowned end of the nozzle body forms.
  • the onset is not a separate nozzle is necessary, but the nozzle body itself forms the circulating body with flow channel, the nozzle and the spherical end for support in the recess.
  • the nozzle body at least in the area of the spherical end made of plastic consists, in particular of polyether ether ketone.
  • the material pairing glass fiber reinforced polyamide / polyether ether ketone is particularly low-wear, so that high with a pairing of such plastics Downtimes can be achieved, although no special ones Bearing body are provided. Overall, this allows the manufacturing costs and the manufacturing costs reduce significantly, because it is enough nozzle body and plastic hoods in the usual way of production can then manufacture these parts used without further changes in the rotor nozzle become.
  • the rotor nozzle shown in the drawing is attached to the End of a feed line 1 attached to cleaning liquid, via the supply line from a high pressure cleaning device is introduced under high Deliver pressure in a compact jet that runs along one Cone jacket runs around.
  • the feed line 1 opens into a housing foot 2, which is essentially the shape of a pot with an external thread 3 has.
  • the mouth of the supply line 1 takes place centrally, the supply line 1 through the Bottom 4 of the cup-shaped housing foot 2 passes through and up to about the upper edge 5 of the cup-shaped housing foot 2 runs.
  • the supply line is in this area 1 closed on the front, but one leads Opening 6 out of the feed line 12, which is so oriented is that emerging from this opening 6 Liquid has an essential component that is in a plane lying vertically on the feed line 1 lies and with respect to the longitudinal axis of the feed line 1 runs in the circumferential direction.
  • hood 7 screwed on, which together with the housing base 2 forms a closed housing.
  • This hood 7 points on the side opposite the housing base 2 flared outlet opening 8, which in Towards the inside of the case a conical depression 9 is upstream, which is concentric with the outlet opening 8 is arranged and an opening angle of has about 130 °.
  • This recess 9 forms a pan-shaped bearing for the crowned end 10 of a substantially tubular one Nozzle body 11 which is continuous in the longitudinal direction
  • Flow channel 12 has.
  • This flow channel 12 ends in a nozzle opening 13 which is central from the crowned end 10 emerges and with the outlet opening 8 is aligned.
  • the tubular nozzle body 11 carries on its crowned End 10 opposite end outside two circumferential O-rings 14, 15 which are Support on the inner wall 16 of the hood 7.
  • the nozzle body 11 is made entirely of plastic, preferably made of polyether ether ketone, also the housing is preferably made of plastic, for example made of polyamide with a glass fiber content of 30%.
  • the particularly stressed storage area between the crowned end 10 and the recess 9 in the inner wall the hood 7 shows surprisingly with such a construction little wear, so with such Long service life can be achieved.
  • the parts are easy to manufacture because the Hood 7 is formed as a one-piece molding, and the same applies essentially to the nozzle body 11.
  • These parts can also be exchanged in the simplest way are unscrewed from the housing base 2 by the hood 7 and is replaced by a new one. At this Opportunity can also be the nozzle body 11 in simpler Be exchanged in case the wear is a certain one Dimension should exceed.
  • the Supply line 1 opens directly into the interior of the housing foot 2.
  • the housing base 2 is towards the hood 7 closed by a cover 17 via a seal 18, here too the liquid is over one in this Drawing not shown tangentially in the initiated by the hood 7 area.
  • the nozzle body 11 is in the illustrated embodiment of Figure 2 formed in several parts, in the front End of the substantially tubular nozzle body 11 is namely a special nozzle 19 is used, the end protruding from the nozzle body 11 the crowned Forms end 10 of the nozzle body 11.
  • This nozzle body too 11 is made of plastic, as is the one used Nozzle 19, for example made of polyether ether ketone can be manufactured.
  • the rotor nozzle is constructed and works the same also in the same way as that of FIG. 1.
  • the configurations of the two different housing feet also exchanged for example, it is easily possible to have one Nozzle body 11 with nozzle 19 also inserted To use the embodiment of Figure 1 and vice versa.
