  • first axis of rotation is aligned with the longitudinal axis of the Housing coincides and is perpendicular to the second Axis of rotation is arranged and if the ratio of two turns is 45:43, then it is in Optimal with regard to a uniform spray pattern, that the acute angle of the V formations is about 40 ° be. With this arrangement of the axes of rotation uniform rotary movements with simple means be generated.
  • the nozzles can be under optimal use of the small installation space be advantageously long to the quality of the liquid jet and the effectiveness of the Improve cleaning.
  • a turbine and a gearbox for driving the rotatable nozzle arrangement in this way are arranged that from the supply line under Pressure inflowing cleaning fluid the housing flows through and drives the turbine before turning it off emerges from the nozzles, you get a slim Device for insertion into narrow Tank openings is suitable and a simple one Includes drive for the two rotary movements a thorough and even cleaning of the Ensure tank interior surfaces.
  • the invention can be further improved in that between one around the rotational movement of the nozzle arrangement the second axis of rotation driving element and the Drive shaft of the nozzle arrangement an angular play of approximately 180 ° is provided. This will put in the area the angular play an alignment of the nozzle arrangement in the longitudinal direction of the housing from any Rotation position allows without the Rotary drive should be activated. One can therefore those for insertion into a narrow tank opening possibly not correctly positioned Align the nozzle arrangement by hand without the Having to turn the drive elements and without otherwise required for the drive Consuming cleaning liquid unnecessarily.
  • Angular play is the drive shaft with a radial protruding pin beyond its outer diameter provided that in a direction of rotation over a Angle range of 180 ° extending recess in Hub area rotatable on the drive shaft stored bevel gear engages.
  • Has projection that on the drive shaft rotatable bevel gear in the hub area axially outwards against the first projection protruding, in the same axial area as the first protruding and turning in the direction of rotation extending over an angular range of 90 ° has second projection, so that the relative Rotation between the plate-shaped veneer and the bevel gear against each other in the direction of rotation abutting projections to an angular range of Is limited to 180 °.
  • the protrusions can be on simple way of manufacturing, especially when Cast the bevel gear and the facing with it be molded without further Steps are required, such as inserting one Pin in the drive shaft.
  • Tank cleaning device consists of a housing 1, in a narrow tank opening, not shown is insertable and therefore has a slim shape.
  • the housing has a non-rotatable housing part 2, the at its top a feed opening 3 for connection a feed line, not shown, for the Has cleaning fluid.
  • the Housing 1 has a nozzle holder 4 which is opposite the non-rotatable housing part 2 about a first axis of rotation 5 is rotatably arranged.
  • Nozzle arrangement 6 is rotatable about a second axis of rotation 7 stored.
  • the nozzle arrangement 6 has four nozzles 8, 9, 10, 11, of which two 8, 9 and 10, 11 in the tips Angle 12 of approximately 40 ° to one another as a V formation 13 or 14 are arranged.
  • the two V formations 13, 14 are arranged to each other so that they in opposite directions 15 point. Thereby creates a nozzle arrangement 4 which in the directions 15 has a greater extent than transverse to this Directions 15.
  • the two V formations 13, 14 are symmetrical arranged to each other, the nozzles 9 and 10 in opposite directions 15 and on the other hand, the nozzles 8 and 11 in corresponding point in opposite directions. How best to recognizable in FIG. 1 are the V formations 13, 14 also staggered so that their Tips 16, 17 at a distance from the second axis of rotation 7 lie.
  • the connecting line 18 is between the two tips 16, 17 approximately perpendicular to the respective bisectors 19, 20 of the two acute angle 12.
  • the non-rotatable housing part 2 is elongated and narrowly designed to fit through tight Tank openings fit. Flows through the feed opening 3 Cleaning fluid under pressure in the interior of the housing 1.
  • a turbine 21 arranged with a stator 22 and a rotor 23.
  • the rotor 23 sits on a rotor shaft 24 with the also a sun gear 25 of a planetary gear 26 is rotatably connected.
