Definitions

  • the invention relates to a rotor nozzle for a high-pressure cleaning device with a housing, which is provided in a front wall with a pan-shaped bearing for the front spherical end of a nozzle body having a through-bore, with an inlet for a liquid which opens tangentially into the housing. through which the liquid in the housing can be set in rotation about the longitudinal axis of the housing, so that the nozzle body rotates together with the rotating liquid and, with its contact surface, rests on the circumference of the inner wall of the housing, the longitudinal axis of the Nozzle body is inclined towards the longitudinal axis of the housing.
  • Such a rotor nozzle is known, for example, from German Patent 40 13 446.
  • Such a rotor nozzle results in a particularly simple construction, since the nozzle body is only supported on one side, and otherwise but moves freely in the housing, on the one hand it rotates on a conical jacket around the longitudinal axis of the housing, while on the other hand it rotates about its own longitudinal axis.
  • This rotary movement about its own longitudinal axis can be largely reduced by providing increased friction in the area of the contact surface.
  • this does not succeed in reducing the rotational frequency of the nozzle body in the housing.
  • a brake body is mounted displaceably in the longitudinal direction of the nozzle body at its rear end facing away from the front, spherical end, and in that a contact surface is arranged in the housing adjacent to the rear end of the nozzle body, on which the bearing surface mounted in the nozzle body is arranged
  • the brake body bears above the end of the nozzle body as soon as the nozzle body rotates in the housing.
  • a brake body is therefore mounted in the nozzle body, which can move in the direction of the longitudinal axis of the nozzle body. Since this longitudinal axis is inclined to the longitudinal axis of the housing and thus to the rotating axis when the nozzle body rotates in the housing, the centrifugal force also results in a component which displaces the brake body in the direction of the longitudinal axis of the nozzle body and which pushes the brake body out of the nozzle body against the presses front face.
  • This system produces an effective braking force which limits the rotational frequency of the nozzle body in the housing, this speed limitation working independently of the position of the nozzle body about its longitudinal axis.
  • the nozzle body can therefore rotate freely about its longitudinal axis, and nevertheless the rotational frequency of the nozzle body in the housing is effectively restricted.
  • the braking forces increase with an increasing rotational frequency.
  • the brake body which can be formed, for example, as a steel body, also exerts an increasing radial component on the nozzle body due to its high weight with increasing speed, which increases the force of the nozzle body presses against the inside wall of the housing. This in turn helps to further reduce the self-rotation of the nozzle body about the longitudinal axis.
  • the brake body can be a ball, for example.
  • a particularly simple embodiment is obtained if the brake body is freely displaceably mounted in a cylindrical blind hole at the rear end of the nozzle body.
  • the contact surface for the brake body can be designed as an annular surface which is arranged in the contact region of the brake body perpendicular to the longitudinal axis of the nozzle body. Overall, the contact surface thus has a slight taper due to the inclination of the longitudinal axis of the nozzle body relative to the longitudinal axis of the housing.
  • the contact surface can have a central projection which projects into the interior of the housing via the rear end of the nozzle body supported in the pan-shaped bearing. This ensures that even before the nozzle body is put into operation, it does not align centrally in the housing, but maintains an inclination with respect to the longitudinal axis of the housing. At the start of operation, the nozzle body is therefore immediately effectively pressed against the inner surface of the housing.
  • the Umlau frequency of the nozzle body in the housing is additionally reduced in a preferred embodiment of the invention in that the nozzle body on at least two mutually offset in the direction of its longitudinal axis contact surfaces on its circumference on the inner wall of the housing. Due to the inclined position of the nozzle body in the housing, the rolling movement of the nozzle body on the inner wall of the housing results in rolling paths of different lengths for the contact surfaces on the inner wall of the housing, so that slippage occurs in this area. This slip additionally brakes the orbital movement of the nozzle body in the housing and thus contributes to limiting the orbital frequency.
  • the reduction in the rotational frequency of the nozzle body by means of two contact surfaces which are offset with respect to one another in the direction of the longitudinal axis of the nozzle body is particularly advantageous in combination with a brake body which is freely movable in the longitudinal direction of the nozzle body and which rests on an end-face contact surface and in turn a reduction in the rotational frequency causes.
  • the measure of the two longitudinally offset contact surfaces can also be used alone to reduce the rotational frequency, for example by providing two or more contact surfaces in the longitudinal direction on a nozzle body which has no movable brake body.
  • the reduction in the rotational frequency can be improved in such a solution if the end region of the nozzle body, in which the contact surfaces are located, has an increased weight, be it through a massive design of the nozzle body in this region or by embedding a weight.
  • This reduction in the rotational frequency by at least two contact surfaces without a combination with a movable brake body resting on the end face is the subject of the invention.
  • the contact surface can be formed, for example, by O-rings.
  • the inner wall of the housing runs parallel to the longitudinal axis of the nozzle body abutting the inner wall and carries the nozzle length bearing surface with the same outer diameter.
  • the at least two contact surfaces are arranged in the region of the rear end of the nozzle body and surround the bearing of the brake body in the nozzle body.
  • the drawing shows a longitudinal section through a rotor nozzle with limitation of the rotational frequency of the nozzle body.
  • the rotor nozzle shown in the drawing comprises a housing 1 with a rear half 2 which is cup-shaped and has a central opening 4 in its base 3.
  • a connection piece 5 is formed on this opening 4 on the underside of the bottom 3, with the aid of which the housing 1 can be screwed onto the end of a jet pipe of a high-pressure cleaner, for example.
  • a front half 6 is screwed into the rear half 2 of the housing 1 by means of an O-ring seal 7 is sealed against the first half 2.
  • the second half 6 is essentially frustoconical and ends at its narrow end in an end wall 9 provided with a central opening 8, in which a pan-shaped bearing 10 surrounding the opening 8 is held.
  • a nozzle body 12 In this bearing 10 the spherical front end 11 of a nozzle body 12 is supported, which essentially comprises a nozzle 13 and an adjoining hollow cylinder 14.
  • the nozzle 13 is firmly inserted into one end of the hollow cylinder 14, the interior of the hollow cylinder 14 is connected to a nozzle bore in the nozzle 13.
  • Windows 15 are arranged in the side wall of the hollow cylinder 14 and establish a flow connection between the interior of the hollow cylinder 14 on the one hand and the interior of the housing 1 on the other.
  • the hollow cylinder 14 has a somewhat larger diameter than in the rest of the region and here forms a receiving bore 17 for a spherical brake body 18 which is free in the receiving bore 17 parallel to the longitudinal axis of the nozzle body 12 is guided.
  • the hollow cylinder 14 On the outside, the hollow cylinder 14 carries two O-rings 19 and 20 at an axial distance from one another in the area surrounding the receiving bore 17, both of which bear against the inner wall 21 of the second half 6 of the housing 1.
  • This inner wall 21 runs parallel to the longitudinal axis of the nozzle body 12 applied to the inner wall, so that both O-rings 19 and 20, which are arranged on the cylindrical outer wall of the hollow cylinder 14, are pressed onto the inner wall 21 with the same force.
  • an insert 22 Inserted into the rear half 2 of the housing 1 between its base 3 and the lower edge of the front half 6 is an insert 22 which extends essentially parallel to the base 3 and which is secured by means of an O-ring seal 23 against the inner wall of the rear half 2 of the Housing 1 is sealed.
  • the insert 22 forms, together with the base 3, a distributor space 24 which, on the one hand, is connected to the opening 4 in the base 3, on the other hand, with bores 25 in the insert 22 entering the interior of the housing 1 obliquely with tangential component from the distributor space 24.
  • the insert 22 On the side facing the interior of the housing, the insert 22 has a projection 26 projecting centrally into the interior of the housing, which protrudes beyond the rear end 16 of the nozzle body 12 and thus prevents the nozzle body from being able to align itself centrally in the housing 1.
  • the projection 26 is surrounded by an annular contact surface 27 which is oriented essentially perpendicular to the longitudinal axis of the nozzle body 12 resting against the inner wall of the housing 1.
  • This contact surface 27 is located at a short distance from the rear end 16 of the nozzle body 12, so that the brake body 18, which is freely displaceable in the receiving bore 17, can come to rest against the contact surface 27 as long as it is still in the receiving bore. bore 17 is located.
  • the housing 1 is surrounded by a two-part outer housing 28, which can be made of plastic, for example. It surrounds the housing 1 in a jacket-like manner, in the region of the connecting piece 5 and in the region of the opening 8 the housing 1 passes through the outer housing 28.
  • high-pressure cleaning liquid is introduced via the connecting piece 5 and the opening 4 in the distributor space 24 and from there passes through the bores 25 into the interior of the housing 1. This results in a space around the longitudinal axis of the housing in this interior rotating fluid filling. This takes the nozzle body 12, which is supported in the bearing 10 with the spherical end 11 and is pressed with the O-rings 19 and 20 against the inner wall of the front half 6 of the housing 1.
  • the liquid escapes from the interior of the housing 1 via the windows 15 and the nozzle 13 in the form of a compact jet of cleaning agent, this jet circulating on a conical jacket which passes through the opening 8.
  • the increased forces with which the two O-rings 29 and 20 are pressed against the inner wall of the front half 6 of the housing 1 act in the same direction. Since the distances to be covered by each of the two O-rings during a revolution in the housing along the conical inner wall are different, a slip occurs between the O-rings 19 and 20 on the one hand and the inner wall on the other hand, which also determines the revolution frequency limited. This effect is increased by increasing the contact forces with which the O-rings 19 and 20 are pressed against the inner wall under the influence of the brake body 18 as the speed increases.
  • the construction of the rotor body is designed so that assembly and disassembly is possible with little effort.
  • the insert 22 is first inserted into the rear half 2 of the housing 1, then the front half 6 of the housing 1 is screwed to the rear half 2 with a nozzle body inserted into the bearing 10.
  • the spherical brake body 18 is loosely inserted into the nozzle body 12, and the O-rings 19 and 20 are also attached.
