Furthermore, a sprinkling device has become known, which leads to the action of the water turbine, which alternately interacts with one of a side stream of the 43 channels, and has a spray water via slide controls on both sides of the pivot point around which the switching element has an openable piston, the axial distance between two shifts closing one of these channels can be pivoted via a spiral guide in a higher position. The um-watering pipe can advantageously be given a pivoting movement. Through . Switching device have a spring element which, when the piston stroke is changed, the pivoting range 50 of the pivoting movement can be adjusted from the center to the eicer. In the usual direction of rotation, the sprinkler pipe carries the spray openings in a manner that is different from the central position.

The water flows through the other channel to the Turbine, so that the previously acted upon channel is exposed to the pressure prevailing behind the turbine and again a differential pressure holding the switching element is built up.

According to an advantageous feature of the invention, a particularly reliable switchover is thereby achieved achieved that a link is provided that at 10 to several the pivoting near the reversal point on the toothing and a stop on which the switching elements are, acts and this switches at the reversal point After Dap switching element causes a sudden increase in _

The turbine causes a pressure drop, so that even if the spray openings are still sufficient, part of the fact that there are hardly any resistances due to the elimination of the crank or eccentric gear. On the other hand, it may be due to the good lubrication, since all gear parts are in the liquid to be sprayed. It has been found that almost the entire device can be made of plastics.

The bores are in it has two end sections 11, 12, which are set after these indentations in such a way that they go through the sides of the end of the essentially cylindrical center of an imaginary sphere, from a three-dimensional device. The end sections 45 of the sections 31 part of the surface bilhave the form of hoods, the end portion being the. This ensures that the Spritzöffnun-11 has a hub 13 which has an internal thread 14 gene an outlet edge that bears a circumferential line. A connecting piece of the bore is formed in the internal thread 14. In other words: The spray 15 is screwed in that the fluid inlet 16 is formed, openings 30 are not cut off at an angle, although they are. The connecting piece 15 is at its outer 5 », its axes are inclined relative to the cylindrical housing J end for interaction with a plug-in coupling. 'which is located at the end of a hose (not a ί made of metal is shown in the hollow axle 18). In a stepped part 17 shaft 32 inserted, which is rotatably inserted in a bearing 33 of the hub 13, a hollow axle i8, which is mounted. The bearing 33 is a journal bearing which, as also shown in FIG. 3 it can be seen, a number of ss arranged on a partition wall 34 of the housing 27 ■ has longitudinal grooves. In the illustrated embodiment is. The partition wall 34 divides in the housing 27 a beispiei five longitudinal grooves 19 are provided, from the liquid-filled chamber 35 and runs in which four are evenly distributed over the circumference essentially over the entire Qusrschniitsfläche the, while one of the longitudinal grooves is also between the housing.

It thus forms 60 uninterrupted openings 30 in order to form a channel 36 into an identification groove, which form an incorrect assembly, which makes it impossible for the liquid to close the spray openings.

The nozzles are arranged in such a way that each of them drives the turbine in a contrary direction of rotation. They are fed via channels 43, 44 (FIG. 7).

The entire transmission is carried by a carrier 53 which is attached to the hollow sleeve 18 and can also be formed in one piece with this. As already mentioned, it should be noted that in FIG. 1 the transmission is pivoted through 45 ° for the purpose of better illustration (see also FIG. 6).

From F I g. 6 it can be seen that the pinion S1 is in mesh with an internal toothing 54 which is formed on an insert 55. The insert 55 is in the housing? is inserted from the left in FIG. 1 and the hollow axle 18 protrudes through it. Opposite this it is sealed by an O-ring 56. The internal toothing S4 extends approximately over half the circumference and, in the example shown, is offset with its axis of symmetry by 45 ° relative to the vertical. It is arranged in such a way that the pinion engages in the center position shown on the axis of symmetry of the internal toothing. _'Dt In the lower part of the insert 39, the loadings are formed, 40th They form in Fig. 1 to the right of the nozzles 42, 42 lugs 57 which serve to / fix the insert against rotation. ¹ For this purpose, a plug 58 is arranged between them, which closes a drain opening 59 in the housing 27, and is fixed by means of a bayonet catch and sealed by means of an O-Itingcs. The stopper 58, which is preferably made of plastic, carries a molded needle 60 which is provided for cleaning the injection opening 3Q.

The outer sides of the V-legs form two sealing surfaces ^l t 3, 74, 43 which can zusEimmenwirken, 44 alternately to the two ends of the channels.

also the Eintlringsa of SrJuuntz between mechanically moved teeth.

It has proven that the entire mechanics of movement had a very good degree of efficiency Da3 is largely due to the fact that all mechanically moved TeQs are always immersed in liquid (with the appearance of the larger and less loaded bearings 26, ^ f). The varwesdeten KunstsioSe have good NaßlaafeigeMchafteQi so Dab Schmietuag with the used mostly as spray water fully · stMndif have ample pressure that the located "in the chamber 35 fluid exerts on the hollow shaft 118 and the father a ReaktkMsdrack to the O-ring Sd" This would be largely eliminated by the dynamic reaction of the liquid when it was diverted to the passage 7 into the chamber 15. The openings 68 in the hollow axis are therefore susfeblldet in such a way that they sink the liquid by essentially 90 °. The relief effect is particularly advantageous if the angle of rotation is more than 90 °, and it is advantageous that the total amount of fluid that escapes from the injection dysentery contributes to this effect The area of the sleeve clamps is offset in diameter. housings are used.
