    An advantage obtained with a device according to claim 1 is that the operational reliability of the device becomes higher compared with other devices in the technical field when using liquid comprising particles through the device.
    Preferred embodiments of the device according to the invention have furthermore been given the features set out in subclaims 2 to 16.
    According to an embodiment of the invention, the first gear is arranged on a second shaft. The first gear is fixedly connected to the second shaft. The first gear rotates in a plane parallel to the axis to which the worm screw is arranged. An effect of this is that the rotation of the first axis can thus be transmitted to the second axis.
    According to a further embodiment of the invention, the second shaft with a part is provided with threads forming a second worm screw. The second shaft is rotatably connected in a fastening element. The fastening element is connected to the rotatable part of the housing.
    An effect of the second worm screw is that the number of gears in the gear can thus be reduced compared to a gear using only gears.
    According to a further embodiment of the invention, the threads of the second worm screw fit into threads of a second gear. The second shaft is caused to rotate by the first gear driven by the first worm screw. One effect of this is that the rotation of the worm screw can thus be transferred to the second gear.
    According to a further embodiment of the invention, the second gear is arranged on a third shaft. The second gear is configured to rotate in a plane parallel to the second shaft. The second worm screw and the second gear form a second worm gear between each other. One effect of the second gear is that it transmits its rotation to the third shaft.
    According to a further embodiment of the invention, the third shaft is arranged with a third gear. The second gear is fixedly connected to the third shaft. Furthermore, the third gear is fixedly connected to the third shaft. The second and third gears are spaced apart on the third shaft.
    According to a further embodiment of the invention, the third axis is parallel to the first axis. The third shaft is rotatably connected to the fastening element as above.
    According to one embodiment, this fastening element can be a free-standing fastening element separate from the first fastening element. The fastening element is then fastened inside the housing in the same way as the first fastening element. An effect of the first and third shafts being parallel to each other is that the gear in the rotatable part becomes compact and thus not space-consuming.
    According to a further embodiment of the invention, the second shaft is arranged perpendicularly to at least one of the first or a third shaft. Due to the perpendicular position of the second shaft in relation to at least one of the first or the third shaft, a solution is obtained which makes the gear compact inside the housing. According to a further embodiment of the invention, a turbine flow passage is arranged between the stationary part and the rotatable part. The turbine flow passage extends from the stationary part to the rotatable part. Centrally through the turbine flow passage, the shaft with the rotation-generating element and the worm screw is arranged. One effect of the turbine flow passage is to direct the liquid from the stationary part to the rotatable part. An additional effect of the turbine flow passage is to be designed so that a turbine can be arranged in it.
    According to a further embodiment of the invention, the turbine flow passage is connected to the stationary part by a locking ring. The locking ring is arranged on the inside of the turbine flow passage. A number of recesses are provided through the wall portion of the turbine flow passage. The recesses can be continuous through the wall portion of the turbine flow passage. A fastening element is arranged in each recess. The fastening element has a length whereby when it is arranged in the recess and through the wall portion a part of it protrudes on the outside of the turbine flow passage. On the inside of the turbine flow passage, the fastening element is formed with a main mold having a diameter larger than the recess. The fastening element can thus not slide through the recess because its head prevents this. The locking ring presses against the respective head on the inside of the turbine flow passage. This keeps the fastening elements in place in the respective recesses. Respective fastening elements extending on the outside of the turbine flow passage fit into an inner edge portion arranged in the stationary part. When fitting against that edge portion of the fastening element, the turbine flow passage is thus statically connected to the stationary part.
    According to a further embodiment of the invention, the turbine flow passage is provided with an external plateau. The outer plateau has a side facing the stationary part.
    According to a further embodiment of the invention, the outer plateau is configured to abut against a bearing. The inner edge portion of the stationary part has a bottom side facing the rotatable part. A space is arranged between the outer plateau of the turbine flow passage and the bottom side of the inner edge portion of the stationary part.
    As a result, the bearing between the stationary part and the rotatable part can thus be arranged in a protected manner in the device.
    According to a further embodiment of the invention, the bearing is arranged against a bearing ring. The bearing can also be designed as an integral part of the bearing ring. An effect of the bearing ring is that it cooperates with the outer plateau of the turbine flow passage, the intermediate bearing being kept positioned therebetween.
    According to a further embodiment of the invention, the bearing ring is connected in the rotatable part. The connection is such that the bearing ring is attached to the rotatable part. Threads are provided in the portion of the rotatable member adjacent to the stationary member. 10 15 20 25 30 35 4 The threads in that portion are arranged internally on the rotatable part. The bearing ring is arranged with external threads. The bearing is configured to be connected with its threads to said arranged threaded member of the rotatable part in the portion adjacent to the stationary part. As previously mentioned, the bearing is arranged between the bearing ring and the outer plateau of the turbine flow passage. The bearing ring is configured to, when attached to the rotatable member, have a static position relative to the rotatable member. Rotation between the stationary part and the rotatable part thus takes place between the bearing ring and the outer plateau, between which the above-mentioned bearings are arranged.
    The rotatable part is connected to the stationary part in that the outer plateau of the turbine flow passage is arranged inside the rotatable part inside the bearing ring. Since the bearing ring is connected to the rotatable part, the stationary part with the turbine flow passage is connected to the rotatable part.
    According to a further embodiment of the invention, the rotation generating element is arranged substantially in the stationary part. By arranging the rotation-generating element in the stationary part, a compact solution of the device is obtained since the associated worm gear is thereby arranged in the rotatable part.
    According to a further embodiment of the invention, the rotation generating element is a turbine. By using a turbine, an efficient utilization of the flow through the device is obtained to generate rotation of the shaft extending through the turbine flow passage.
    According to a further embodiment of the invention, the rotation generating element is arranged in the housing. Furthermore, the worm gear is arranged in the housing. An effect of this is that the entire housing can thus be manufactured and sold as a compact unit comprising the rotation-generating element and worm gear.
    According to a further embodiment of the invention, the housing is configured to be arranged inside the enclosed space. This means that the housing can be arranged inside the enclosed space when manufacturing the enclosed space, or the housing can be such that it is arranged inside the enclosed space with fastening devices when the enclosed space is to be cleaned.
    According to an embodiment of the invention, the device can be designed such that the housing for the device for flushing the closed space is arranged inside the closed space and gear, e.g. the worm gear, and the rotation generating element are arranged outside the closed space. The gear unit is arranged in the same way as previously described in the flow which is led in the direction of the spray nozzles. In this embodiment with gear and rotation generating elements arranged outside the closed space, rotation is transmitted to the rotatable part and the hub by means of a shaft or wire which is brought into rotation from the rotation generating element, e.g. turbines. Brief Description of the Drawings A preferred embodiment of the device according to the invention will now be described in more detail with reference to the accompanying schematic drawings, which show only the details necessary for understanding the invention.
    Fig. 1 shows a device according to the invention in a cross section from the side.
    Fig. 2 shows a device according to the invention in a cross section from behind.
    Fig. 3 shows a device according to the invention in a cross-section from the side with the main flow path through the device.
    Detailed description of different embodiments of the invention Fig. 1 shows a device for cleaning closed spaces by means of a sprayed-out liquid. The device comprises a housing 1 with partly a stationary part 2 and partly a rotatable part 3. A hub 4 is arranged against the rotatable part. On the hub 4 a number of spray nozzles 5 are arranged. In the housing 1 a shaft 6 is arranged. This shaft 6 extends from the inside of the stationary part 2 and into the inside of the rotatable part 3. On a part of the shaft 2 a rotation generating element 7 is arranged. On a second part of the shaft 2 a number of threads are arranged forming a worm screw 8. The shaft 6 runs centrally through a turbine flow passage 17. The turbine flow passage 17 is configured to direct liquid from the stationary part 2 to the rotatable part 3.
    The shaft 6 extending centrally through the turbine flow passage 17 is with the part arranged with the worm screw 8 positioned inside the rotatable part 3. The shaft 6 has at this part a lower end which rests against, or is rotatably connected to, a support element inside the rotatable part 3. The worm screw 8 is configured to cooperate with a first gear 9 (see Fig. 2). Together, the worm screw 8 and the first gear 9 form a worm gear 10. The first gear 9 is arranged on a portion of a second shaft 12, which shaft 12 is perpendicular to the first shaft 6. On a second portion of the second shaft 12 is a second worm screw 13 (see Fig. 1) arranged. This second worm screw 13 is configured to cooperate with a second gear 14 arranged on a third shaft 15. The third shaft 15 is arranged parallel to the first shaft 6. The second gear 14 rotates in a plane parallel to the stretch of the second shaft 12. The second gear 14 and the second worm screw 13 on the second shaft 12 together form a second worm gear.
    The third shaft 15 is arranged with a third gear 16. This third gear 16 is configured to cooperate with a first gear ring 22. Said first gear ring 22 is arranged externally on the turbine flow passage 17.
    The turbine flow passage 17 is arranged with a second ring gear 23. This second ring gear 23 cooperates with a third ring gear 24 for driving the hub 4. The rotatable part 3 comprises a portion adjacent to the stationary part 2 which is arranged with a first bearing ring 21 and fixed in the rotatable part 3. In the portion of the rotatable part 3 adjacent to the stationary part 2, threads are arranged.
    The threads in that portion are arranged internally on the rotatable part 3. The bearing ring 21 is arranged with external threads. The bearing ring 21 is configured to be connected with its threads to said arranged threads in the rotatable part 3 in the portion adjacent to the stationary part 2. The bearing ring 21 is configured to be statically connected to said rotatable part when attached to the rotatable part 3 The bearing 20 is arranged between the first bearing ring 21 and an outer plateau 19 of the turbine flow passage 17.
    The turbine flow passage 17 is connected to the stationary part 2 by a first locking ring 18. The locking ring 18 is arranged on the inside of the turbine flow passage 17. Through a wall portion 25 of the turbine flow passage 17 a number of recesses 26 are arranged. The recesses 26 are continuous through the wall portion 25 of the turbine flow passage 17. In each recess 26 in the turbine flow passage 17 a fastening element 18 is arranged. The fastening element 27 has a length whereby when arranged in and through the recess 26 and through the wall portion 25 a part of it protrudes on the outside of the turbine flow passage 17. On the inside of the turbine flow passage 17 the fastening element 27 is formed with a main shape having a diameter larger than the recess 26. The fastening element 27 can thus not slide through the recess 26 because its head prevents this. The locking ring 18 in the turbine flow passage 17 is pressed against the respective head of the respective fastening element 27 on the inside of the turbine flow passage 17. This thereby holds each fastening element in place in the respective recesses by means of resilient force from the locking ring 18. Respective fastening elements 27 extending outside the turbine flow passage 17 fits into an inner edge portion 28 arranged in the stationary part 2. When fitting against the inner edge portion 28 of the fastening element 27, the turbine flow passage 17 is thereby connected to the stationary part 2.
    Fig. 3 shows the device according to Figs. 1 and 2 with flow path 11 for the liquid through the device. The flow path 11 of the liquid through the device and the housing extends from and through the stationary part 2, through the turbine flow passage 17, into and through the rotatable part 3, to the hub 4 and then out through the spray nozzles 5. The gear is arranged so in the rotatable part 3 that the main part of the flow with liquid is led through the worm gear towards the spray nozzles 5. This means that it is not so-called leakage flow conducted through the gear unit. Because the gear 10 is arranged in the flow path 11, the gear is thus flushed through by the main part of the liquid which is led towards the spray nozzles 5.
    The hub 4 is arranged with the rotatable part 2. Between the hub 4 and the rotatable part 3 a second bearing ring 29 is arranged. This second bearing ring 29 is arranged in the rotatable part 3 in a manner corresponding to the first mentioned bearing ring 21. The hub 4 extends with a tubular part 30 into the rotatable part 3 in the direction of the flow path 10 15 20 25 30 35 7 11. The tubular part 30 of the hub 4 with part arranged inside the rotatable part 3 is arranged with recesses (not shown in the figure) in its wall, called hub wall 31. Through these recesses other fastening elements 32 are arranged. These second fastening elements 32 are provided with a main mold with the part positioned on the inside of the tubular part 30. The fastening elements 32 are resiliently held in place by a second locking ring 33 which abuts the respective head of the respective second fastening elements 32. The respective second fastening element 32 through respective recesses in the hub wall 31 extends on the outside of the tubular part 30. The tubular part 30 is arranged through a toothed ring 34 with an externally arranged third ring gear 24. The toothed ring 34 is arranged on its inside with a groove 35, in which groove the other fastening elements 32 with their outer part opposite its head are arranged in. Through this the hub 4 is thus arranged with and to the rotatable part 3.
    During operation of the device, the liquid is led in through an inlet arranged in the stationary part 2. From the stationary part 2 the liquid is led through the turbine flow passage 17 and on to the rotatable part 3. In the turbine flow passage 17 a rotation generating element 7, a so-called turbine, arranged. From the flow of the liquid through the device, the turbine 7 and the first shaft 6 are caused to rotate. The shaft 6 is arranged at its one end with a first worm screw 8 which cooperates with a first gear 9 and which first gear 9 is caused to rotate by the first worm screw 8. The first gear 9 is arranged on a second shaft 12 which is arranged with a second worm screw 13. The rotational movement of the first gear 9 is transmitted via the second shaft 12 to the second worm screw 13. Said second worm screw 13 cooperates with a second gear 14 arranged on a third shaft 15. This third shaft 15 is caused to rotate and transmit its rotation via a third gear 16 arranged on this third shaft 15 to a first ring gear 22 arranged on the turbine flow passage 17.
    The turbine flow passage 17 has a static position relative to the stationary part 2. When driving the third gear 16 against the first gear ring 22, the rotatable part 3 is caused to rotate about a first center axis 36 centrally extending through the first shaft 6. On the outside of the turbine flow passage 17 a second ring gear 23 is also provided.
    This second ring gear 23 cooperates with a third ring gear 24 connected to the hub 4. Upon rotation of the rotatable part 3 about said first center axis 36, the third ring gear 24 with the hub 4 is caused to rotate around a second center axis 37 extending centrally through the second ring gear 23. and the tubular part 30 of the hub 4 is thereby caused to spray out from the spray nozzles 5 arranged on the hub 4 in a movement where the rotatable part 3 and the hub 4 with the spray nozzles 5 rotate around the first center axis 36, and partly in a movement where the hub 4 and the spray nozzles 5 relative to the rotatable member 3 rotate about the second center axis 37. This causes the device with the liquid to clean all surfaces in a closed space. The respective stretches of the first and second center axes 8 (36, 37) intersect at a point inside the rotatable part 3. The respective stretches of the first and the second center axes (36, 37) form a substantially right angle between each other.
    The invention is not limited to the embodiment shown but can be varied and modified within the scope of the appended claims, which has been partly described above. 10 15 20 25 30 35 Reference numerals: housing stationary part rotatable part hub spray nozzle shaft rotary generating element worm screw first gear worm gear flow path second shaft second worm screw second gear third shaft third gear turbine flow passage plate locking tooth first wall tooth bearing ) fastening elements inner edge portion second bearing ring tubular part hub wall second fastening elements second locking ring cogging groove OONCTJCTIJÄOOIU-X 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 first center shaft second center shaft 10 36 37
