Definitions
- the invention relates to a rotor nozzle for a high-pressure cleaning device with a housing, a turbine rotor rotatably mounted therein, which is flowed by a cleaning fluid and is thereby rotated, and with a nozzle arranged downstream of the rotor, the outlet axis of which forms an acute angle to the axis of rotation of the rotor and which is rotated by the rotor about its axis of rotation in such a way that the emerging jet of cleaning liquid revolves on a conical jacket.
- Such a rotor nozzle is known from German Patent 34 19 964.
- the nozzle which is part of the rotor, is supported on the housing by means of a ball bearing.
- this area of the ball bearing can be used over a long period of time Sealing problems arise.
- a rotor nozzle of the type described in the introduction in that the nozzle is arranged in a stilt which is supported with a spherical end in a pan which is open in the middle and held on the housing, while at the other end one with the rotor connected, engages at a radial distance from the rotor axis of rotation engages, which allows a free rotation about the longitudinal axis of the stilt relative to the rotor.
- Such a construction changes the longitudinal axis of the stilt and thus the direction of the emerging jet with the speed of rotation of the rotor, i.e. the jet runs at a speed of the rotor along a conical circumferential surface, but on the other hand the support surface of the stilt rotates on the pan not at the same - possibly very high - speed, since the stilt can rotate freely about its longitudinal axis relative to the rotor.
- the speed of the stilt about its own longitudinal axis is significantly lower than the speed of the rotor, so that the wear in the area of the pan is significantly reduced.
- There is also a very advantageous seal in the area of the pan since the stilt with the spherical end is firmly against the pressure of the cleaning liquid passing through the nozzle Pan is pressed. This results in a perfect seal in this area.
- a driver that allows the stilt to rotate freely about the longitudinal axis can be constructed in different ways, for example the driver can be designed as a pointed pin that dips into a central recess at the other end of the stilt.
- a configuration has proven to be particularly advantageous in which the driver is designed as a pan-shaped recess into which the other end of the stilt is immersed. This other end is preferably spherical.
- the pan can also have a spherical bottom with adjoining conical walls.
- the stilt comprises an essentially cylindrical plastic body, into which a nozzle body made of metal is inserted.
- Conventional nozzle bodies can be used, which are also used in high-pressure cleaning devices. These consist of particularly abrasion-resistant hard metal or steel, they can have an integrated rectifier.
- the nozzle body forms the spherical end lying against the pan and if the pan is made of plastic.
- the metal / plastic pairing then results in particularly favorable storage conditions.
- the stilt has lateral inlet openings for the cleaning liquid.
- the radial distance of the driver from the axis of rotation of the rotor is adjustable.
- the angle of inclination of the longitudinal axis of the stilts with respect to the axis of rotation can also be changed, and thus also the angle of the exit jet with respect to the axis of rotation.
- centrifugal weights are movably arranged on the rotor, which are acted upon by spring means in a position close to the axis of rotation, and that one of the centrifugal weights carries the driver.
- centrifugal weights are applied to the inner wall of the housing when a maximum speed of the rotor is reached and thereby brake the rotor.
- the centrifugal weights then also act as a centrifugal brake.
- the rotor nozzle shown in FIG. 1 comprises a housing 1, which consists of an expanding influencing part 2 and an outflow part 3 screwed into it. Outflow part 3 and influence part 2 are sealed against one another by means of an annular seal 4.
- the influencing part 2 has a central inflow opening 5, which has an internal thread 6 for connection to a jet pipe of a high-pressure cleaning device, which is not shown in the drawing and is known per se.
- a deflection element 8 is screwed into a central bore 7, which has flow channels 9 for a cleaning liquid flowing into the housing via the inflow opening 5.
- the flow channels 9 end in a bottom 10 of the influencing part 2 formed by the influencing part 2 and the deflecting element 8 screwed therein.
- a central pivot pin 11 is held in the deflecting element 8 and protrudes from the deflecting element 8 into the open interior of the influencing part 2.
- a rotor 12 is rotatably mounted on this pivot pin 11, which comprises an inner bearing body 13 acting as a flywheel mass and a turbine body 14 held in an annular manner thereon.
- the turbine body consists, in a manner known per se, of individual blades which are arranged in the outlet region of the flow channels 9 in such a way that the rotor 12 is set in rotation about the pivot pin 11 by liquid emerging from the flow channels 9.
- a snap ring 15 is provided for axially fixing the rotor 12 to the pivot pin 11.
- the bearing body 13 can be made of bearing bronze, for example, while the turbine body 14 is usually made of plastic, for example polyoxymethylene.
- the fluid emerging from the turbine body 14 collects in an order to the opposite steering element 8 collecting space 16, which is formed by the outflow part 3.
- the collecting space 16 opens into a conically narrowing, central extension 17, which is closed off by means of an end wall 18.
- a central, conically widening outlet opening 19 is arranged in the end wall 18.
- annular pan 20 made of plastic, for example made of polyester. It is sealed off from the inner wall of the outflow part 3 by means of an annular seal 21 and has a central passage opening 22 which at the downstream end first has a conically narrowing bearing area 23 and then a conically widening outlet area 24.
- the outlet area 24 is designed such that the likewise conically widening outlet opening 19 in the end wall 18 continuously adjoins the outlet area 24.
- a spherical stilt 25 In the conically narrowing extension 17 of the outflow part 3 and in the collecting space 16 there is a spherical stilt 25.
- This consists of an essentially cylindrical plastic part 26 with a step-like narrowing central blind hole 27 which is open to the outlet opening 19.
- a nozzle body. per 28 made of metal, for example made of steel, which protrudes with a spherical end 29 from the plastic part 26.
- the spherical end 29 dips into the bearing area 23 of the pan 20 and supports the stilts 25 in the pan 20.
- the plastic part 26 ends in a peg-shaped extension 30, which is also spherical at its free end 31.
- This spherically shaped end 31 immersed in a pan 32 acting as a driver integrally to the - is formed turbine body fourteenth
- the pan 32 has a spherical bottom 33 in cross section, which is adjoined by a conically opening side wall 34. It is arranged at a radial distance from the axis of rotation of the rotor 12 defined by the pivot pin 11, so that the longitudinal axis of the ball stem 25 encloses an acute angle with respect to the axis of rotation of the rotor formed by the pivot pin 11.
- the plastic part 26 has lateral inflow openings 35 for the cleaning liquid, which in this way reaches the blind hole 27 from the collecting space 16.
- the nozzle body 28 is open at its end inserted into the plastic part 26 and is in the form of a rectifier 36. Downstream of the rectifier 36 is a central nozzle opening 37, which initially narrows and then has a continuous cross section, which opens into the outlet region 24 of the pan 20. Through the nozzle body 28, the cleaning liquid flowing into the blind hole 27 in the form of a sharp jet passes through the outlet opening 19 into the open.
- the direction of the exit jet coincides with the longitudinal direction of the stilt 25, so it is inclined with respect to the axis of rotation of the rotor 12.
- the inclination is determined by the radial distance of the pan 32 from the axis of rotation.
- the cleaning liquid flows through the inflow opening 5 and the throughflow channels 9 through the turbine body 14, which is thereby set in rotation. From the collecting space adjoining the turbine body 14, the cleaning liquid then passes through the ball stilts 25 and the nozzle body 28 as a sharp jet into the open.
- the pan 32 which acts as a driver, also runs in a circular path around the axis of rotation of the rotor, so that the stilts 25 are carried along a conical surface, the tip of which lies in the center of the spherical end 29 of the nozzle body 28. This also results in a movement on the outwardly opening conical surface for the exit jet of the cleaning liquid.
- the spherical end 29 of the nozzle body 28 is pressed strongly against the bearing area 23 of the pan 20 by the liquid, so that a good seal is achieved in this area. Since the ball stilts 25 can rotate freely about their longitudinal axis both with respect to the pan 20 and with respect to the pan 32, the ball stilts rotate during operation about their own longitudinal axis, the speed of which is substantially below the speed of the rotor, that is to say the Ball stilts 25 essentially perform a wobbling movement in the pan 20 without a strong rotation about its own longitudinal axis occurring. As a result, the bearing formed by the pan 20 and the spherical end 29 of the nozzle body 28 is protected during operation.
- FIGS. 2 and 3 which is constructed essentially similarly, corresponding parts are provided with the same reference numerals.
- the pan 32 which serves as a driver for the ball stilts 25, is not connected in one piece or rigidly to the turbine body 14.
- two centrifugal weights 39 and 40 are mounted on the rotor 12 by means of L-shaped arms 41 and 42, respectively, about bearing shafts 43 and 44 running transversely to the axis of rotation of the rotor 12 and at a distance therefrom.
- the arms 41 and 42 each carry one of the centrifugal weights 39 and 40 on the legs 45 and 46, which run essentially parallel to the axis of rotation of the rotor, while the legs 47 and 48, which run essentially perpendicular to the axis of rotation of the rotor 12, are thereby pivotally and displaceably coupled to one another.
- a tension spring 51 is arranged between the legs 45 and 46 and pivots the two centrifugal weights 39 and 40 into their position close to the axis of rotation (FIG. 2).
- the two centrifugal weights 39 and 40 lie opposite each other in pairs symmetrically to the axis of rotation of the rotor.
- the socket 32 into which, as in the exemplary embodiment in FIG. 1, the spherical end 31 of the spherical stilts 25 is immersed.
- the centrifugal weights 39 and 40 are arranged in the collecting space 16 and are designed such that they finally come to rest against the inner wall 52 of the outflow part 3 when they are pivoted outwards.
- the two centrifugal weights 39 and 40 are in a position close to the axis of rotation, before being switched on, in which they are brought by the tension spring 51.
- the pan 32 acting as a driver is arranged essentially on the axis of rotation of the rotor, so that the longitudinal axis of the spherical stilts 25 coincides with the axis of rotation of the rotor (FIG. 2).
- the liquid jet With a low liquid supply nothing changes, so that in this operating position the liquid jet initially coincides with the axis of rotation of the rotor.
- the centrifugal weights 39 and 40 pivot outward against the force of the tension spring 51 (FIG. 3), so that the pan 32 acting as a driver has a larger decrease received from the axis of rotation of the rotor.
- the opening angle of the cone shell depends on the speed of the rotor. At low speed, the opening angle is small, it increases with increasing speed.
- the two centrifugal weights 39 and 40 rest against the inner wall 52 and brake the rotor, so that the centrifugal weights also serve as a centrifugal brake.
- the paired arrangement of the centrifugal weights 39 and 40 means that unbalance of the rotor is avoided.
