  • the distribution wall 48 further comprises a calibrated orifice 58 screwed into the central duct 56 and facing the opening 24 of liquid inlet.
  • the inside diameter of this orifice makes it possible to precisely define a fluid inlet section in the central duct 56.

  • the tangential ducts 60 are rectilinear along a respective axis, said drive axis X e -X e .
  • Each tangential duct 60 extends from a frustoconical inlet face 61 of the wall 48 to a planar face 63 of the latter.
  • the drive axis X e -X e of each tangential duct is contained in a plane P e parallel to the axis of rotation XX, located at the same distance d of this axis XX.
  • the drive axis X e -X e forms a non-zero angle ⁇ of about 135 ° with the projection of the axis of rotation XX in the plane ( figure 4 ).
  • the tangential ducts 60 are uniformly distributed around the axis of rotation X-X, that is to say that each tangential duct 60 corresponds to the previous tangential duct, moved in rotation by a constant angle. This angle is equal to 90 ° in the illustrated example.
  • Each tangential duct 60 is therefore able to generate, from the liquid introduced through the inlet opening 24, a tangential jet in the corresponding drive axis.
  • Each tangential duct 60 defines an outlet section of the liquid whose center is at a distance from the axis of rotation.
  • the center is at the point of the plane P e closest to the axis of rotation XX, that is to say at the distance d of this axis XX.
  • each tangential duct 60 defines an inlet section of the liquid.
  • the ratio between the inlet sections of the tangential ducts and the inlet section of the calibrated orifice 58 is chosen so that, as a function of the flow of liquid provided through the opening 24, the tangential jets generated entrain the nozzle 14 at a constant speed of rotation, constant, of the order of a few revolutions per minute.
  • the drive wall 50 has the shape of a disk extending opposite the flat, outlet face 63 of the disk 52 of the distribution wall 48, between this disk 52 and the nozzle 14. .
  • the driving wall 50 is pierced on its thickness along the axis of rotation XX, of a conduit 62 for passage and guiding of the chimney 54.
  • the drive wall 50 is thus mounted in rotation around the chimney 54.
  • the diameter of this disc is slightly smaller than the inside diameter of the body 18, to allow its rotation in the latter.
  • the drive wall 50 is also pierced on its thickness with a plurality of conduits 64 for receiving the tangential jets.
  • the number of ducts 64 is nine.
  • the receiving ducts 64 are rectilinear and oriented parallel to the axis of rotation XX. They are distributed circularly about the axis of rotation XX, uniformly. Their center is substantially at the distance d from the axis of rotation XX, corresponding to the distance d between the center of the outlet of each tangential duct of the same axis of rotation XX.
  • Three cylindrical recesses 66 are furthermore arranged along the X axis in the drive wall 50, each recess 66 opening out towards the tube 27, so as to align with one of the recesses 46 of the nozzle 14.
  • the device 10 comprises three locking keys in rotation extending parallel to the axis of rotation XX, at a distance from the latter. On the figure 1 only one key 68 is visible. Each key 68 is engaged, at one end, in one of the locking recesses 46 provided for this purpose in the nozzle 14 and, at another end, in one of the complementary locking recesses 66, facing them in the wall 50. 'training.
  • the wall 50 is rigidly connected to the nozzle 14, for example by forcing the keys 68 into force.
  • first and second circular ribs 70, 72 are provided on the drive wall 50, in the direction of the distribution wall 48.
  • the receiving ducts are disposed between the ribs 70 and 72.
  • the first rib 70 extends at the periphery of the drive wall 50, outside the ducts 64 of reception.
  • the second rib 72 extends between the duct 62 for passage and guiding of the chimney 54 and the receiving ducts 64.
  • each tangential duct 60 has a circumferential dimension L around the axis of rotation XX, that is to say tangential to the geometric circle of radius d and centered on the axis of rotation XX, greater than the distance l separating two successive reception ducts around the axis of rotation XX. So, a tangential stream is always received, at least in part, by a channel 64 of reception.
  • the distribution wall 48 and the drive wall 50 are free to move slightly along the axis X.
  • the wall 48 is capable of moving axially between the shoulder 25 and the retaining ring 51.
  • Cleaning liquid is introduced through the inlet opening 24. This liquid pushes the distribution wall 48 against the shoulder 25.
  • the tangential conduit entries 60 are thus released, that is to say they are no longer covered by the ring 51.
  • the friction between the shoulder 25 and the distribution wall 48 prevents the rotation of this wall 48 around the axis of rotation XX.
  • the tangential jets are directed towards the space between the two circular ribs of the drive wall 50.
  • these jets are channeled on the receiving ducts 64 and the risk of liquid passing around the periphery of the drive wall 50 between this wall 50 and the body 18 is small.
  • the passage of the tangential jets in the receiving ducts 64 causes the rotation of the drive wall 50 around the axis of rotation X-X, the latter driving in turn the nozzle 14 thanks to the keys 68.
  • the liquid After having passed through the drive wall 50, the liquid, projected in the form of tangential jets, arrives in the body 18 of the flow conduit 12, before joining the central jet in the main duct 38 via the diametrical conduit 44 .
  • the cleaning liquid is thus brought in its entirety through the main duct 38 into the ball 29, from which it will be projected to the outside through the heads 31A, 32A, 33A and 34A projection.
  • the pressure drop generated by the rotational drive of the nozzle is low, so that the projection pressure is close the supply pressure unlike what happens in the nozzles of the prior art where the supply pressure is essentially used to rotate the nozzle. Since the energy of the tangential jets is used either to rotate the nozzle 14 or to create the projection pressure, there is no energy loss. Moreover, unlike the known nozzles where the speed of rotation is a function of the supply pressure, the rotational speed of the nozzle of the invention can be adjusted so that it rotates regularly around the nozzle. rotation axis XX; this is done by adjusting the inlet section of the calibrated orifice 58.
