Definitions
- the invention relates to a sprinkler according to the preamble of Claim 1.
- the fluid usually water
- the fluid is to be discharged via a relatively long distance from e.g. several meters from Sprinkler head or sprinkler outlet are removed so that it covers a predetermined irrigation field, most of the time is approximately horizontal or a horizontal position Forms the basis of measurement.
- the water from the outside adjacent sprinkler exit via a free jet path, mostly a parabola-like throwing track, released under pressure and off there is no further contact with or immediate exit
- the fluid jet is guided through the sprinkler more.
- sprinklers can be used during the Operation stationary output or such used in which the fluid jet is one to its longitudinal direction transverse transverse movement e.g. thereby conveyed is that the sprinkler head is approximately parallel to the irrigation field and / or transverse movement, like a constant one rectified and / or a reciprocating rotary movement or executes an axial movement.
- To the fluid jet To be able to discharge as far as possible is approximate horizontally or approximately vertically upwards or downwards directional orientations of the exit one below about 30 preferred up to 45 ° inclined upward orientation, where z. B. by rod-shaped or extendable upwards Training the sprinkler head a relatively high location of the exit opposite or above the irrigation field can be.
- Such a sprinkler is e.g. B. in the EP patent application 410 198 or in EP patent application 362 559 described on the inclusion of those explained there Features and effects related to the present invention is taken.
- the fluid flow is appropriately chosen so that it is linearly calm Flow is fed to the nozzle outlet, and the fluid jet leaves the nozzle outlet as a so-called pricking jet, which the fluid outlet as possible without substantial spraying leaves sharply bundled and also bundled over several meters can stay.
- This stinging beam then fanned in greater distance from the fluid outlet and irrigated Irrigation field of predetermined area size with an average Irrigation density per unit area, which is appropriate over the Irrigation field is essentially constant.
- the exit or the place last touch of the fluid jet with the sprinkler Beam perturbator is formed that is rhythmic in the stab is moved and thereby a spray for each time causes the close range.
- the short spray pulses are usually sufficient not out, the close range or the field between the irrigation field the jet and the sprinkler with about the same Irrigation density like the sting irrigation field too water. Even if the lancing jet or the sprinkler outlet by a jerky transverse movement from a rest position in a next one is moved during this impulse movement the range of the fluid jet is slightly reduced, but not in such a way that the close range in the is irrigated.
- a sprinkler has become known from US-A-4,281,793 although drive means for reversing the direction of the transverse movement of the Fluid jets and a control device for changing the Has beam width, but this control device works completely independent of the reversal of direction, namely depending from the angular position of the sprinkler head a control unit.
- the control device is used for Passage cross section of a control disc changed, whereby different throttle cross sections and therefore also result in different throughputs of the water.
- the invention is also based on the object of a sprinkler to create the disadvantages of known training or of the type described are avoided and in particular with a long range, e.g. in the direction of its beam axis irrigation field enlarged towards the sprinkler with over the extent of which is approximately uniform ensures that in the top view also a sprinkler up to a few meters or less than one meter from the controller removed or possible right up to the sprinkler exit is.
- the sprinkler should be as safe as possible in operation or less susceptible to interference or in the area of Sprinkler output no movements during operation have executing parts or control elements.
- the features according to claim 1 intended. They include means to keep the fluid inside it Sprinkler head or in the flow direction in front of the exit to influence or redirect with regard to a flow, that it is the sprinkler in very different jet shapes or leaves with very different ranges.
- the different jet shapes are from the sprinkler expediently at least partially in succession delivered, e.g. immediately and essentially without interrupting the discharge adjoining each other or with less Overlap such that the discharge of the subsequent jet shape shortly before the termination of the previous one Beam shape begins. It is conceivable to have more than two different ones Provide jet shapes and limit them appropriately the two irrigation fields each have two different ones Beam shapes essentially overlap or overlap they each other slightly, so that complete irrigation given is.
- a manually operated changeover drive expediently one is provided which runs during the operation of the sprinkler and according to predetermined Time or path intervals make the switchover.
- the drive energy is expedient to that of the sprinkler flowing fluid removed, the drive itself the Flow alternately in the manner described can influence.

- the flow can be influenced by numerous different ones Measures are effected, each one individually or can be provided in combination.
- a automatically in different functional positions during operation transferable and / or manually adjustable or adjustable flow disturbance member can be provided in a Position a relatively linear and calm flow to the exit and in at least one other Position this flow with effect swirled to the exit.
- separate fluid paths can be provided which the flow differs in the manner described influence and alternately stronger or weaker flows through or at least partially through closure locked or opened.
- Separate flow paths can by separate channel sections or a common channel section or a chamber can be formed in which alternately flows in different directions or is led over different distances, e.g. B. through guiding surfaces.
- the water for a Jet shape in a flow roller rotating around the channel axis be guided while it is for the other beam shape less strong or essentially not rotating and with Appropriate flow behavior reached the exit.
- a chamber adjoining and opposite expediently many times narrower and not axially symmetrical Intake of a channel section alternately in different Directions are poured towards each other Flow direction a different flow behavior of the water in this section of the canal and the water with it Flow behavior essentially led to the exit becomes.
- guide surfaces can be moved by hydropower be or form wide chambers in which the water e.g. B. in a rotary motion over a rotational path of more than 90, 180 or approximately 270 degrees.
- one of the described in the fluid guide Switchable between different throttle effects Throttle can be provided through which the flow volume or the fluid pressure at the outlet is changed.

- the actuator 36 moves between manually adjustable independently, not attacks shown in detail, which are mounted on the base are. If the actuator 36 hits a stop, so it becomes about an axis 22 and its longitudinal axis right-angled axis pivoted by a few degrees and takes over one within the control chamber 14 lying control rocker the closing member from the previous one Tax position in the other tax position an intermediate spring so that the closing member 34 resilient pressed against the associated valve seat and thereby the Fluid enters the control chamber 17 from a fluid nozzle 18 or 19 is switched to the other.
- the attacks can on the one hand the angular position and on the other hand the angular size irrigation sector.
- Control device 10 serves as a drive rotor for this transmission, which offset two axially parallel to the rotor axis 21 lying gear shafts 41 with one another alternately engaging gear wheels and in one of the Fluid guide 13 separate, dry gear chamber on the away from the control chamber 14 or the fluid nozzles 18, 19 Side of the axes 21, 22 lies.
- the valve 33 also serves as a reversing valve of the reversing control 9, by switching from a fluid nozzle 18, 19 to the others the direction of rotation of the control rotor 20, the transmission and the drive pinion 42 is reversed in the opposite direction, so that the sprinkler head 5 changes its direction of rotation.
- control rotor 20 At the higher speed of the control rotor 20 arises a stronger swirling of the water flow in the control chamber 17 than at the lower speed, so that once Spray jet and the other time a pricking jet is generated.
