Definitions
- the invention relates to a rotor nozzle for a high-pressure cleaning device having a housing which has at least one tangentially opening into the housing inlet for a liquid and which is provided in an end wall with a pan-shaped, centrally perforated recess, and arranged in the housing, having a passage channel and with a spherical end in the pan-shaped recess supporting nozzle body whose longitudinal axis is inclined to the longitudinal axis of the housing, wherein liquid in the housing through the at least one inlet into the housing inflowing liquid about the longitudinal axis of the housing is set in rotation and the nozzle body circulates together with the rotating liquid and thereby rests with a contact surface on its circumference to the inner wall of the housing.
- Such rotor nozzles are known for example from DE 41 29 026 Cl. With their help, a compact liquid jet circulating on a conical surface can be produced, which can be directed onto a surface to be cleaned for cleaning purposes, for example.
- the inlet of the housing can be connected to a high-pressure cleaner, so that the housing can be supplied under high pressure liquid.
- a nozzle body which is mounted only on one side of the pan-shaped recess and can move in the housing about the longitudinal axis of the housing, moreover.
- the nozzle body has a passageway through which the liquid can pass through the perforated recess of the housing.
- the longitudinal axis of the nozzle body is inclined relative to the longitudinal axis of the housing.
- the nozzle body By tangentially entering the housing liquid, the nozzle body is in the pan-shaped Pressed recess, which forms a bearing for the nozzle body, and at the same time the nozzle body is set in rotation about the housing longitudinal axis.
- the supply of the pressurized fluid over the tangentially into the housing opening inlet ensures that fluid in the housing is rotated about the longitudinal axis of the housing and thereby rotates the nozzle body to the housing longitudinal axis by within the housing a rotating liquid column formed.
- the at least one tangential inlet forms a flow resistance for the liquid, which leads to flow losses.
- the diameter of the at least one tangential inlet could be increased.
- this then has the consequence that the flow velocity of the liquid in the region of the at least one tangential inlet decreases, and this in turn can result in that the nozzle body is not reliably displaceable in all cases in rotation about the housing longitudinal axis.
- start-up behavior of the nozzle body can be impaired.
- the startup behavior is understood to mean the start of the rotation of the nozzle body.
- the nozzle body Before the housing is supplied under pressure fluid, the nozzle body is relative to the inner wall of the housing at rest, so he does not perform any circulation movement around the housing longitudinal axis. If the supply of pressurized liquid now occurs via the at least one tangential inlet, then first the static friction between the nozzle body and the inner wall of the housing has to be overcome in order to prevent the To be able to set the nozzle body in rotation. Thus, a relatively large initial frictional force must first be overcome to move the nozzle body.
- the sliding friction which is usually less than the initial static friction, is responsible for the friction behavior of the nozzle body on the inner wall of the housing. This has the consequence that for maintaining a rotational movement of the nozzle body about the housing longitudinal axis a lower force is required than for the start of the movement.
- the flow cross-section of the at least one tangential inlet is increased in order to reduce flow losses in the region of the inlet, this reduces the flow velocity of the liquid in the region of the inlet, which in turn can lead to liquid being transferred to the nozzle body applied force is insufficient to enable the nozzle body in rotation about the housing longitudinal axis.
- Object of the present invention is to develop a rotor nozzle of the type mentioned in such a way that flow losses in the rotor nozzle can be reduced without thereby the operation of the rotor nozzle, in particular the startup behavior of the nozzle body, is significantly affected.
- a rotor nozzle of the generic type according to the invention that the nozzle body has a deviating from the circular outer contour in a the front, spherical end facing away from the rear end.
- the region of the nozzle body extends with an outer contour deviating from the circular shape to directly at the rear end of the nozzle body. It has been shown that this is a particularly effective allows the same force transmission from the liquid rotating about the housing longitudinal axis of the nozzle body.
- the nozzle body In its region with an outer contour deviating from the circular shape, the nozzle body has a non-circular shape which enables an effective transmission of force from the rotating fluid to the nozzle body.
- the nozzle body can in this area, for example, have an oval shape or a wavy outer contour.
- the nozzle body is designed to be angular in the region with an outer contour deviating from the circular shape.
- the nozzle body may be formed, for example, star-shaped or in the form of a polygon, in particular a square or hexagon.
- the provision of edges in the region of the outer contour of the nozzle body allows a particularly efficient transfer of forces from the liquid rotating about the housing longitudinal axis of the nozzle body so that it follows the movement of the liquid and also rotates about the housing longitudinal axis.
- the nozzle body in its rear end region on the outside protruding ribs.
- the ribs give the nozzle body a deviating from the circular outer contour.
- ribs extend in a radial plane relative to the longitudinal axis of the nozzle body.
- the nozzle body may, for example, have a plurality of circumferentially uniformly distributed ribs, which are each aligned radially.
- at least some ribs extend perpendicular to a radial plane relative to the longitudinal axis of the nozzle body.
- a radial plane is understood to mean a plane which is aligned in the radial direction with respect to the longitudinal axis of the nozzle body.
- a plurality of ribs are aligned parallel to each other.
- the liquid rotating in the housing about its longitudinal axis can not only result in the nozzle body rotating around the housing longitudinal axis corresponding to the liquid.
- the liquid rotating about the longitudinal axis of the housing can act as a rotary drive for the nozzle body about its longitudinal axis, in particular in the front region of the nozzle body, with which it is mounted in the central cup-shaped depression, so that it is rotated in its own longitudinal axis about its own rotation.
- the self-rotation about the longitudinal axis of the nozzle body is superimposed on the orbital motion of the nozzle body on the conical surface of the housing. The self-rotation causes the liquid jet emerging on the nozzle body to rotate about its longitudinal axis.
- the liquid jet can fan out. This can have the consequence that the cleaning effect of the liquid jet already decreases at a short distance from the nozzle body.
- the nozzle body has a circular outer contour in its end region facing the front, spherical end. The circular outer contour reduces the transmission of forces from the liquid rotating in the housing to the nozzle body in the front region of the nozzle body. The danger that the liquid jet after leaving of the nozzle body fanned, is kept low.
- the nozzle body thus has in its rear end region a deviating from the circular outer contour, which improves the startup behavior of the nozzle body, and in its front end region, the nozzle body has a circular outer contour, the self-rotation of the nozzle body to its own longitudinal axis low holds.
- a cylindrical configuration of the nozzle body in its front end region is of particular advantage.
- the region with a circular outer contour extends over at least half of the total length of the nozzle body.
- the nozzle body in its rear end region on a deviating from the circular outer contour extends at most over half the total length of the nozzle body.
- the region with an outer contour of the nozzle body that differs from the circular shape is preferably shorter than the region with a circular outer contour relative to its longitudinal axis.
- the region extends with an outer contour deviating from the circular shape in the longitudinal direction of the nozzle body over a maximum area of 40% of the total length of the nozzle body. It has been shown that a particularly good start-up behavior can be achieved with a relatively low intrinsic rotation of the nozzle body.
- the nozzle body revolving around the housing longitudinal axis abuts against the inner wall of the housing with a contact surface.
- the contact surface is formed by a torus, which is rotatably connected to the nozzle body
- annular bead in the longitudinal direction of the nozzle body on both sides join areas with deviating from the circular outer contour.
- the annular bead is arranged in such an embodiment at a distance from the rear end of the nozzle body, and both in the area between the annular bead and the rear end of the nozzle body and in the adjoining the annular bead in the direction of the front end of the nozzle body area of the Nozzle body on a deviating from the circular outer contour.
- the annular bead can be formed, for example, by an O-ring which is frictionally connected to the nozzle body and which is arranged in an annular groove surrounding the nozzle body.
- the annular bead in particular the O-ring, is preferably made of a rubber-elastic material.
- the above-described self-rotation of the nozzle body about its own longitudinal axis can be reduced by the nozzle body has a centrifugal force-increasing mass element in its rear end region.
- On- Because of its rotation about the longitudinal axis of the housing of the nozzle body is subject to a centrifugal force which acts on the nozzle body perpendicular to the housing longitudinal axis and presses against the inner wall of the housing.
- the self-rotation of the nozzle body is obstructed about its own longitudinal axis.
- the centrifugal force acting on the nozzle body can be increased by increasing the mass of the nozzle body in its rear end region. It is therefore advantageous if it has a mass element in this end region, for example a metal body.
- a spherical mass element is used, for example a metal ball, in particular a steel ball.
- the liquid supplied to the housing via the at least one tangential inlet can leave the housing only in that it flows through the passage channel of the nozzle body and then passes through the perforated recess on the end wall of the housing.
- the passageway extends in the axial direction through the nozzle body. The liquid can thus enter the passage at the rear end of the nozzle body and leave it at the front end of the nozzle body. It has been found that the cleaning effect of the rotor nozzle is improved by such a passage.
- the passageway has a relatively large length. This calms turbulence in the liquid flow. Such turbulences can lead to a fanning out of the liquid jet flowing out of the nozzle body.
- the relatively large length of the passageway reduces the risk of turbulence. It is particularly advantageous if a rectifier is arranged in the passage, because turbulence in the liquid jet can be calmed particularly effectively.
- the rectifier may have walls running parallel to the longitudinal axis of the nozzle body, which pass diametrically through the through-channel.
- the rectifier has two mutually perpendicular, parallel to the passage and extending these diametrically penetrating walls.
- a centrifugal force-enhancing mass element is arranged in the rear end region of the passage channel, which can be flowed around by the liquid.
- the mass element can be pressed into the through-channel. This facilitates the assembly of the nozzle body.
- a rectifier is arranged in the passage, which connects in the direction of the front, spherical end of the nozzle body to the mass element.
- the liquid can flow through the nozzle body axially, wherein it enters the passage at the rear end of the nozzle body and initially flows around the preferably spherical or cylindrical mass element. Subsequently, the liquid flows through the rectifier, which adjoins the mass element in the direction of the front end of the nozzle body.
- the rectifier results in a calming of the liquid jet by attenuating turbulence within the liquid jet. A practically turbulence-free liquid flow can be achieved, so that the risk is particularly low that the liquid jet fanned out when leaving the nozzle body.

- Figure 3 is a sectional view taken along line 3-3 in Figure 1 and
- FIG. 4 shows a sectional view along the line 4-4 in FIG. 1.
- a rotor nozzle 10 is shown schematically for a not shown in the drawing high-pressure cleaner, which is screwed onto a jet pipe 12 of the high-pressure cleaner.
- the jet pipe 12 is shown only in part in the drawing, since it is known to those skilled in the art. It comprises a pipe section 13, to whose not shown in the drawing, the rotor nozzle 10 end facing in a conventional manner, the pressure hose of the high-pressure cleaner can be connected, and a connecting portion 14 with an external thread 16 for releasably connecting the jet pipe 12 with the rotor nozzle 10th
- the rotor nozzle 10 has a housing 20 with a first housing part 21 and a second housing part 22, which define an interior 24.
- the first housing part 21 has a frustoconical front Gepuruseab- cut 26 with an end wall 28 and a jacket 30, and a rear housing portion 32 which integrally connects to the front housing portion 26 and is formed as a hollow cylinder. It carries an internal thread 34, in which the connecting portion 14 of the jet pipe 12 is screwed with its external thread 16.
- a cylindrical sealing section 36 adjoins the internal thread 34, which merges into the substantially frustoconical interior space 24 via a shoulder 40 directed radially inward relative to the longitudinal axis 38 of the housing 20.
- the second housing part 22 is configured in the form of a closure plate 42 which limits the interior 24 in the axial direction and rests on the one hand on the shoulder 40 and on the other hand on the free end 44 of the jet pipe 12.
- a closure plate 42 which limits the interior 24 in the axial direction and rests on the one hand on the shoulder 40 and on the other hand on the free end 44 of the jet pipe 12.
- In the end wall 28 facing away from the direction of the end plate 42 connects to the jet pipe 12 in the circumferential direction surrounding sealing ring 46, which ensures a liquid-tight connection of the jet pipe 12 with the rotor nozzle 10.
- the end plate 42 has a plurality, preferably four, in the circumferential direction at a uniform distance from each other arranged tangential inlet 48, via the liquid which is supplied to the rotor nozzle 10 via the jet pipe 12 from a high-pressure cleaner, can enter the interior 24. Due to the tangential orientation of the inlets 48, the liquid entering the interior space 24 has a directional component oriented tangentially relative to the longitudinal axis 38. As a result, liquid 24 is set in rotation in the interior 24 about the longitudinal axis 38 of the housing 20.
- the end wall 28 of the front housing portion 26 has a central opening 50 which widens conically in the direction away from the end plate 22 direction. On the inside, the central opening 50 is surrounded by a cup-shaped bearing ring 52 which carries a sealing ring 54 on the outside and is thereby sealed off from the front housing section 26.
- the spherical front end 56 of a nozzle body 60 is supported.
- This is designed in several parts. It comprises a nozzle 62, which forms the front end 56 of the nozzle body 60, and a nozzle carrier 64 with a passage 68 extending axially along the longitudinal axis 66 of the nozzle body 60 into which the nozzle 62 is aligned with a nozzle channel aligned with the passage 68 70 is pressed in and stepped in his nozzle 62 facing away from the end region.
- a centrifugal force-increasing mass body in the form of a steel ball 72 is pressed into the passage 68.
- the steel ball 72 is adjoined in the passage 68 in the direction of the nozzle 62 by a rectifier 74, which has two mutually perpendicular walls 75, 76 running parallel to the longitudinal axis 66 of the nozzle body 60 and penetrating the passage 68 diametrically.
- the steel ball 72 can be flowed around in the passageway 68 of liquid, so that after passing through the rectifier 74 and the nozzle 62, these pass through the bearing ring 52 and the central opening 50 and thereby leave the rotor nozzle 10.
- the nozzle carrier 64 has a front peripheral region 78 with a circular outer contour and an adjoining rear circumferential region. rich 80 with deviating from the circular outer contour.
- the outer contour of the rear peripheral region 80 which deviates from the circular shape, is formed by means of ribs 82, 83, 84, 85, 86, 87, 88, 89 projecting on the outside from the nozzle carrier 64. This becomes clear in particular from FIG.
- the ribs 82 and 86 are in this case diametrically opposite and are each radially aligned with respect to the longitudinal axis 66 of the nozzle body 60. In a corresponding manner, the ribs 84 and 88 are diametrically opposite and are radially aligned.
- the ribs 83 and 89 are aligned with each other and parallel to the ribs 84 and 88, and the ribs 85 and 87 are also aligned with each other and aligned parallel to the ribs 84 and 88.
- the spacing of ribs 85 and 87 with ribs 84 and 88, respectively, is identical to the distance ribs 83 and 89 have from ribs 84 and 88, respectively.
- the nozzle carrier 64 in the rear peripheral region 80 has a circumferentially circumferential annular groove 91, in which an O-ring 92 is frictionally held and thereby rotationally fixed.
- the O-ring Relative to the longitudinal axis 66 of the nozzle body 60, the O-ring protrudes in the radial direction beyond the ribs 82 to 89. It forms a contact surface, with which the nozzle body 60 can be applied to the inner wall 94 of the housing 20.
- the ribs 82 to 89 extend in the axial direction to both sides of the O-ring 92, extending as far as the rear end 96 of the nozzle body 60 facing away from the front end 56.
- the ribs 82 to 89 extend over less than half the total length of the nozzle body 60.
- the length of the ribs 82 to 89 is less than 40% of the total length of the nozzle body 60, for example, 30% to 35% of the total length.
- the rotor nozzle 10 is supplied via the jet pipe 12 under high pressure liquid, for example water, from a high-pressure cleaning device.
- the liquid passes through the tangential inlet 48 into the interior 24 of the housing 20 and can leave the interior via the passageway 68, the nozzle channel 70, the bearing ring 52 and thereafter via the central opening 50.
- the interior 24 is filled with liquid during operation of the rotor nozzle 10, which is caused to rotate about the longitudinal axis 38 of the housing 20 by the fluid flowing in via the tangential inlets 48. It thus forms in the interior 24 a rotating about the longitudinal axis 38 liquid column.
- the rotating liquid column takes with it the nozzle body 60 supported by its spherical front end 56 in the bearing ring 52 so that it likewise rotates about the longitudinal axis 38 of the housing 20.
- the nozzle body 60 rests against the inner wall 94 of the housing 20 via the O-ring 92 held non-rotatably on the nozzle body 60.
- the longitudinal axis 66 of the nozzle body 60 is thus inclined to the longitudinal axis 38 of the housing 20.
- the rear peripheral region 80 of the nozzle body 60 is due to the inclination of the
- Nozzle body 60 at least equal to the steel ball 72 on only one side of the longitudinal axis 38 of the housing 20, whereas the front peripheral portion 78 extends on both sides of the longitudinal axis 38 on one side and on the opposite side.
- FIGS. 3 and 4. 3 shows a sectional view perpendicular to the longitudinal axis 38 of the housing 20 at the level of the steel ball 72
- FIG. 4 shows a sectional view perpendicular to the longitudinal axis 38 of the housing 20 approximately in the center of the front circumferential area 78.
- the velocity vectors of the liquid flowing around the rear peripheral region 80 at the level of the steel ball 72 are illustrated in FIG. 3 by the arrows 101 and 102.
- the arrow 101 shows the velocity vector of the liquid flowing around the rear peripheral portion 80 on the radially outer side 98
- the arrow 102 shows the velocity vector of the liquid flowing around the rear peripheral portion 80 at the radial inner side 99.
- the liquid has a higher speed than at the radial inner side, but the direction of the speeds coincides. This has the consequence that in the rear peripheral region 80, which is characterized by a deviating from the circular outer contour, of the liquid column rotating about the longitudinal axis 38 of the housing 20, a considerable force on the nozzle body 60 can be transferred, so that this the orbital movement of the Liquid column follows about the longitudinal axis 38.
- FIG. 4 illustrates the flow conditions of the liquid flowing around the nozzle body 60, as present in the front peripheral region 78.
- the front peripheral region 78 has a relatively short distance from the bearing ring 52. Despite its inclination to the longitudinal axis 38, therefore, the nozzle body 60 on both sides of the longitudinal axis 38 on peripheral areas, which are respectively flowed around by the liquid rotating about the longitudinal axis 38.
- the arrow 104 symbolizes the velocity vector of the liquid which surrounds the front peripheral region 78 on a first side. flows, and the arrow 105 symbolizes the velocity vector of the liquid, which flows around the front peripheral portion 78 on the first side opposite the second side. It can be seen that the velocity vectors 104 and 105 are opposite to each other.
- the liquid flowing around the nozzle body 60 in the front peripheral region 78 therefore has the tendency to drive the nozzle body 60 about its own longitudinal axis 66 for its own rotation.
- the front peripheral region 78 has a circular outer contour in contrast to the rear peripheral region 80, only a relatively small force is transmitted to the nozzle body 60 in the front peripheral region 78 by the liquid rotating around the longitudinal axis 38 of the housing 20. This therefore has a relatively low intrinsic rotation.
- the nozzle body 60 reliably to a circulating movement the longitudinal axis 38 driven without these forces have a self-rotation of the nozzle body 60 result.
- a compact cleaning jet which rotates on a conical surface.
- This compact cleaning jet is particularly suitable for cleaning purposes.
