Description

Die vorliegende Erfindung bezieht sich auf eine Sprühvorrichtung zum Behandeln eines Hohlrauminneren, insbesondere von Hohlrauminnenwänden.The present invention relates to a spraying device for treating a cavity interior, in particular interior cavity walls.

Obwohl auf beliebige zu behandelnde Hohlrauminnenbereiche anwendbar, beispielsweise auch zur Hohlraumkonservierung von Fahrzeugen, Flugzeugen und Schiffen, werden die vorliegende Erfindung sowie die ihr zugrunde liegende Problematik in Bezug auf den Verbrennungsraum eines Motors eines Personenkraftfahrzeugs lediglich beispielhaft näher erläutert.Although applicable to any internal cavity areas to be treated, for example, for the cavity preservation of vehicles, aircraft and ships, the present invention and the underlying problems with respect to the combustion chamber of an engine of a passenger car will be explained in more detail by way of example only.

Zur Konservierung des Verbrennungsraums des Antriebsmotors, beispielsweise eines Kraftfahrzeugs, ist es bei längerer Standzeit des Fahrzeugs erforderlich, den Brennraum und zudem den an diesen angrenzenden Ventilbereich bei Viertaktmotoren bzw. die Einlass- und Auslassschlitze bei Zweitaktmotoren mittels eines Schmier- oder speziellen Konservierungsmittels zu konservieren, um eine Rostbildung auf den metallischen Oberflächen zu verhindern. Eine einfache Möglichkeit, den Brennraum zu erreichen ohne den Motor demontieren zu müssen ist der Zugang über die Zündkerzenbohrung. Durch diese Öffnung kann mit bisher aus dem Stand der Technik bekannten Sprühvorrichtungen der Brennraum nur teilweise erreicht werden. Diese Sprühvorrichtungen bestehen meist aus einem mit Druck beaufschlagten Vorratsbehälter für das Schmier- oder Konservierungsmittel, einem Betätigungsmittel und einem an diesem Betätigungsmittel fixierten Kunststoffrohr mit einer axialen Öffnung, durch die das Schmier- oder Konservierungsmittel an der gewünschten Stelle platziert wird. Im Falle des Motorbrennraums können so je nach der Länge des Kunststoffrohres die Bereiche des Brennraums direkt erreicht werden, die der Zündkerzenbohrung gegenüberliegen. Die Bereiche neben der Zündkerzenbohrung, also der obere Bereich des Brennraums mit dem Ventilbereich bei Viertaktmotoren bzw. den Einlass- und Auslassschlitzen bei Zweitaktmotoren, werden nicht oder nur undefiniert und unzureichend über den entstehenden Sprühnebel erreicht. Eine zufriedenstellende Konservierung des Brennraums ist nicht möglich.For preserving the combustion chamber of the drive motor, for example of a motor vehicle, it is necessary for longer life of the vehicle to conserve the combustion chamber and the adjoining valve region in four-stroke engines or the inlet and outlet slots in two-stroke engines by means of a lubricating or special preservative, to prevent rust on the metallic surfaces. An easy way to reach the combustion chamber without having to disassemble the engine is the access via the spark plug hole. Through this opening can be achieved only partially with previously known from the prior art spraying the combustion chamber. These spray devices usually consist of a pressurized reservoir for the lubricant or preservative agent, an actuating means and fixed to this actuating means plastic tube having an axial opening through which the lubricant or preservative on the desired location is placed. In the case of the engine combustion chamber so depending on the length of the plastic pipe, the areas of the combustion chamber can be reached directly opposite to the spark plug hole. The areas adjacent to the spark plug bore, ie the upper region of the combustion chamber with the valve region in four-stroke engines and the intake and exhaust ports in two-stroke engines are not or only undefined and achieved insufficiently via the resulting spray. A satisfactory preservation of the combustion chamber is not possible.

Aus der Druckschrift US 3,987,963 A , die den Oberbegriff von Anspruch 1 offenbart, ist eine Hochdruck-Flüssigkeitsverteilungsvorrichtung bekannt, in welcher eine Flüssigkeitsquelle über eine Rotationsvorrichtung mit einem Sprühkopf verbunden ist, welcher Ausgangsdüsen aufweist, welche einen Flüssigkeitsstrahl abgeben.
Somit liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Sprühvorrichtung zum Behandeln eines Hohlrauminneren zu schaffen, welche die vorgenannten Nachteile beseitigt.
Diese Aufgabe wird erfindungsgemäß durch die Sprühvorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst.
Demgemäß ist eine Sprühvorrichtung zum Behandeln eines Hohlrauminneren, insbesondere von Hohlrauminnenwänden, mit einem Sprühkopf, welcher eine vorbestimmte 3-dimensionale Geometrie aufweist und einer Behandlungsmittel-Zuführeinrichtung zum Zuführen eines Behandlungsmittels zu dem Sprühkopf vorgesehen, wobei der Sprühkopf mehrere Behandlungsmittel-Austrittsöffnungen aufweist, welche derart angeordnet und in unterschiedlichen Sprührichtungen ausgerichtet sind, dass der 3-dimensionale Raum in einem vorbestimmten Bereich um den Sprühkopf herum mit dem Behandlungsmittel besprühbar ist, wobei die Behandlungsmittel-Zuführeinrichtung zumindest zwei Abschnitte aufweist und diese Abschnitte um die Längsachse der Behandlungsmittel-Zuführeinrichtung zueinander drehbar ausgebildet sind, wobei zumindest einer der Abschnitte der Behandlungsmittel-Zuführeinrichtung mit dem Sprühkopf verbunden ist und ein Betätigungsmittel aufweist, welches den Sprühkopf in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung versetzt, wobei das Betätigungsmittel als mit dem Abschnitt fest verbundener Handgriff ausgebildet ist und wobei eine Länge des zumindest einen Abschnittes derart ausgebildet ist, dass das dem Sprühkopf abgewandte Ende dieses Abschnitts aus dem zu behandelnden Bereich herausragt, wobei die Behandlungsmittel-Austrittsöffnungen des Sprühkopfes als in ihrem Querschnitt verstellbare Düsen ausgebildet und wahlweise deaktivierbar sind.From the publication US 3,987,963 A US-A-5 837 865 discloses a high-pressure liquid distribution apparatus in which a liquid source is connected via a rotary device to a spray head having exit nozzles which discharge a liquid jet.
Thus, the present invention has for its object to provide a spraying device for treating a cavity interior, which eliminates the aforementioned disadvantages.
This object is achieved by the spray device with the features of claim 1.
Accordingly, a spraying device for treating a cavity interior, in particular interior cavity walls, with a spray head having a predetermined 3-dimensional geometry and a treatment agent supply means for supplying a treatment agent to the spray head, wherein the spray head comprises a plurality of treatment agent outlet openings, which are such arranged and aligned in different spraying directions, that the 3-dimensional space in a predetermined area around the spray head can be sprayed with the treatment agent, wherein the treatment agent supply means comprises at least two portions and these portions are rotatable about the longitudinal axis of the processing agent supply means, at least one of the portions of the processing agent supply means is connected to the spray head and having an actuating means which the spray head in a rotation around the Offset longitudinal axis of the treatment agent supply means, wherein the actuating means is formed as a fixed portion with the handle and a length of the at least one portion is formed such that the spray head facing away from the end of this section protrudes from the area to be treated, the Behandlungsmittel- Outlet openings of the spray head formed as adjustable in cross-section nozzles and are selectively deactivated.

Somit weist die vorliegende Erfindung gegenüber dem Stand der Technik den Vorteil auf, dass der Sprühkopf mehrere Behandlungsmittel-Austrittsöffnungen aufweist, die in unterschiedlichen Sprührichtungen derart ausgerichtet sind, dass ein vorbestimmter 3-dimensionaler Raum vollständig besprühbar ist. Darüber hinaus wird dadurch, dass die Rotation des Sprühkopfes mittels eines Betätigungsmittels bewirkt wird, eine gleichmäßige Rotation des Sprühkopfes und damit eine auch bei kleinen versprühten Stoffmengen optimierte Verteilung des Behandlungsmittels gewährleistet. Weil der zumindest eine der wenigstens zwei Abschnitte der Behandlungsmittel-Zuführeinrichtung derart ausgebildet ist, dass das eine seiner Enden, welches von dem Sprühkopf abgewandt ist, aus dem zu behandelnden Bereich herausragt, kann die Rotation des Sprühkopfes erreicht werden, ohne dass ein Betätigungsmittel direkt am Sprühkopf selbst vorgesehen werden muss. Somit kann eine Drehung des Sprühkopfes von außerhalb des zu behandelnden Bereichs bewirkt werden. Mittels der vorgesehenen Sprühvorrichtung können also bei der Behandlung eines Hohlrauminneren sämtliche Bereiche des Hohlraums vorteilhaft erreicht werden.Thus, the present invention over the prior art has the advantage that the spray head has a plurality of treatment agent outlet openings, which are aligned in different spraying directions such that a predetermined 3-dimensional space is completely sprayable. In addition, the fact that the rotation of the spray head is effected by means of an actuating means, a uniform rotation of the spray head and thus ensures an optimized even with small quantities of sprayed substance distribution of the treatment agent. Because the at least one of the at least two sections of the treatment agent supply device is formed so that one of its ends, which faces away from the spray head, protrudes from the area to be treated, the rotation of the spray head can be achieved without an actuating means directly on Spray head itself must be provided. Thus, a rotation of the spray head from outside the area to be treated can be effected. By means of the proposed spray device Thus, in the treatment of a cavity interior, all areas of the cavity can be advantageously achieved.

In den Unteransprüchen finden sich vorteilhafte Ausgestaltungen und Verbesserungen der im Anspruch 1 angegebenen Sprühvorrichtung.In the dependent claims are advantageous embodiments and improvements of the claim 1 spray device.

Gemäß einer bevorzugten Weiterbildung ist zumindest eine Behandlungsmittel-Austrittsöffnung der mehreren Behandlungsmittel-Austrittsöffnungen in Richtung und beabstandet von der Behandlungsmittel-Zuführeinrichtung ausgerichtet. Somit ist es möglich, das Behandlungsmittel auch in etwa in Richtung der Behandlungsmittel-Zuführeinrichtung zu sprühen. Dadurch werden, wenn die Sprühvorrichtung durch eine kleine Öffnung in einen Höhlraum eingeführt wird, auch die Bereiche des Hohlraums erreicht, welche angrenzend zu der Einführöffnung liegen.According to a preferred development, at least one treatment agent outlet opening of the plurality of treatment agent outlet openings is aligned in the direction of and spaced from the treatment agent supply device. Thus, it is possible to spray the treatment agent also approximately in the direction of the treatment agent supply means. Thereby, when the spray device is introduced through a small opening in a cavity, the areas of the cavity are reached, which are adjacent to the insertion opening.

Gemäß einer weiteren bevorzugten Weiterbildung weist der Sprühkopf zumindest zwei Segmente in seiner Längsrichtung auf, wobei die einzelnen Segmente bezüglich der Längsachse, der Querachse oder einer weiteren Achse des Sprühkopfs zueinander drehbar sind. Dadurch können sich die einzelnen Segmente entweder während des Sprühvorgangs für eine bessere Verteilung des Behandlungsmittels zueinander verdrehen oder ihre Winkelposition kann voreingestellt werden, um somit gezielt Bereiche des Hohlraums mit der gewünschten Menge Behandlungsmittel zu versorgen.According to a further preferred development, the spray head has at least two segments in its longitudinal direction, wherein the individual segments with respect to the longitudinal axis, the transverse axis or a further axis of the spray head are mutually rotatable. As a result, the individual segments can either rotate each other during the spraying process for a better distribution of the treatment agent or their angular position can be preset, in order thus to supply targeted areas of the cavity with the desired amount of treatment agent.

Gemäß einer weiteren bevorzugten Weiterbildung sind die Behandlungsmittel-Austrittsöffnungen zumindest eines Segments deaktivierbar. Dadurch sind bestimmte Sprührichtungen deaktivierbar, wodurch gezielt Bereiche des Hohlraums von einer direkten Beaufschlagung mit Behandlungsmittel ausgenommen sind.According to a further preferred development, the treatment agent outlet openings of at least one segment can be deactivated. As a result, certain spraying directions can be deactivated, whereby specifically areas of the cavity are excluded from a direct application of treatment agent.

Gemäß einer weiteren bevorzugten Weiterbildung ist die Behandlungsmittel-Zuführeinrichtung als mehrlumige Behandlungsmittel-Zuführeinrichtung ausgebildet. Insbesondere sind mittels einer Blockiereinrichtung, welche zur Blockierung zumindest eines Querschnitts der mehrlumigen Behandlungsmittel-Zuführeinrichtung dient, die Behandlungsmittel-Austrittsöffnungen zumindest eines Segments deaktivierbar. Durch die Blockiervorrichtung, welche beispielsweise durch ein Verdrehen der Behandlungsmittel-Zuführeinrichtung aktiviert wird, ist es möglich, bestimmte Segmente des Sprühkopfs zu deaktivieren. Beim Aktivieren der Blockiereinrichtung werden beispielsweise Schieber vor einzelne Lumen der mehrlumigen Behandlungsmittel-Zuführeinrichtung gefahren oder der Lumenquerschnitt durch ein Zusammendrücken des entsprechenden Querschnitts verschlossen.According to a further preferred development, the treatment agent supply device is designed as a multi-lumen treatment agent supply device. In particular, the treatment agent outlet openings of at least one segment can be deactivated by means of a blocking device which serves to block at least one cross section of the multi-lumen treatment agent supply device. By the blocking device, which is activated for example by a rotation of the treatment agent supply means, it is possible to deactivate certain segments of the spray head. When activating the blocking device, for example, slides are moved in front of individual lumens of the multi-lumen treatment agent supply device or the lumen cross-section is closed by compressing the corresponding cross-section.

Gemäß einer weiteren bevorzugten Weiterbildung variiert die Dichte der Verteilung der Behandlungsmittel-Austrittsöffnungen pro Flächeneinheit auf der Oberfläche des Sprühkopfs. Hierdurch werden bestimmte Bereiche des zu besprühenden 3-dimensionalen Raumes mit einer höheren oder geringeren Menge an Behandlungsmittel beaufschlagt.According to a further preferred development, the density of the distribution of the treatment agent outlet openings per unit area varies on the surface of the spray head. As a result, certain areas of the 3-dimensional space to be sprayed with a higher or lower amount of treatment agent are applied.

Gemäß einer weiteren bevorzugten Weiterbildung sind die Behandlungsmittel-Austrittsöffnungen in einem vorbestimmten Winkel und/oder senkrecht zur Oberfläche des Sprühkopfs angeordnet. Hierdurch wird eine optimale Verteilung des Behandlungsmittels in dem zu besprühenden 3-dimensionalen Raum ermöglicht.According to a further preferred development, the treatment agent outlet openings are arranged at a predetermined angle and / or perpendicular to the surface of the spray head. This allows an optimal distribution of the treatment agent in the 3-dimensional space to be sprayed.

Gemäß einer weiteren bevorzugten Weiterbildung ist der Sprühkopf aus mehreren flexiblen Leitungen ausgebildet, wobei die flexiblen Leitungen jeweils mindestens eine Behandlungsmittel-Austrittsöffnung aufweisen. Da die einzelnen Leitungen flexibel ausgebildet sind, ist die Sprührichtung der einzelnen Leitungen frei einstellbar. Die Behandlungsmittel-Austrittsöffnungen sind sowohl an den Enden als auch an den Mantelflächen der einzelnen flexiblen Leitungen angeordnet.According to a further preferred development, the spray head is formed from a plurality of flexible lines, wherein the flexible lines each have at least one treatment agent outlet opening. Because the individual lines are flexible are formed, the spray direction of the individual lines is freely adjustable. The treatment agent outlet openings are arranged both at the ends and on the lateral surfaces of the individual flexible lines.

Gemäß einer weiteren bevorzugten Weiterbildung ist der Sprühkopf und/oder die Behandlungsmittel-Zuführeinrichtung aus einem flexiblen Material ausgebildet. Durch ein flexibles Sprühkopfmaterial ist es möglich, den Sprühkopf durch Zusammendrücken des flexiblen Materials durch eine Einführöffnung in einen Hohlraum einzuführen. Die Einführöffnung kann dann einen kleineren Durchmesser aufweisen als der maximale Außendurchmesser des Sprühkopfs vor dem Zusammendrücken. Mittels Verwendung eines flexiblen Materials für die Behandlungsmittel-Zuführeinrichtung kann der Sprühkopf durch Biegungen zu dem zu behandelden Hohlraum geführt werden. Weiterhin ist die Stellung des Sprühkopfes im Raum durch Biegen der flexiblen Behandlungsmittel-Zuführeinrichtung vorab einstellbar.According to a further preferred development of the spray head and / or the treatment agent supply means is formed of a flexible material. By means of a flexible spray head material, it is possible to introduce the spray head into a cavity by compressing the flexible material through an insertion opening. The insertion opening may then have a smaller diameter than the maximum outer diameter of the spray head before compression. By using a flexible material for the treatment agent supply device, the spray head can be guided by bends to the cavity to be treated. Furthermore, the position of the spray head in space by bending the flexible treatment agent supply device is adjustable in advance.

Gemäß einer weiteren bevorzugten Weiterbildung sind die Behandlungsmittel-Austrittsöffnungen als austauschbare Wechseldüsen oder erfindungsgemäß als in ihrem Querschnitt verstellbare Düsen ausgebildet. Je nach Anwendungsfall können somit die Größe und/oder die Form des Querschnitts der Behandlungsmittel-Austrittsöffnungen variiert werden. Weiterhin ist es möglich, verstopfte Düsen auszutauschen ohne den vollständigen Sprühkopf austauschen zu müssen.According to a further preferred development, the treatment agent outlet openings are designed as replaceable alternating nozzles or according to the invention as nozzles adjustable in their cross-section. Depending on the application, the size and / or the shape of the cross section of the treatment agent outlet openings can thus be varied. Furthermore, it is possible to replace clogged nozzles without having to replace the complete spray head.

Gemäß einer weiteren bevorzugten Weiterbildung weist der Sprühkopf unterschiedlich große Behandlungsmittel-Austrittsöffnungen auf. Hierdurch kann die Durchflussmenge an Behandlungsmittel in unterschiedlichen Bereichen des Sprühkopfs eingestellt werden.According to a further preferred development, the spray head has different sized treatment agent outlet openings. As a result, the flow rate of treatment agent can be adjusted in different areas of the spray head.

Gemäß einer weiteren bevorzugten Weiterbildung ist der Sprühkopf relativ zu der Behandlungsmittel-Zuführeinrichtung, insbesondere um die Längsachse der Behandlungsmittel-Zuführeinrichtung, drehbar ausgebildet. Dadurch kann sich der Sprühkopf während des Versprühens des Behandlungsmittels im Hohlraum drehen, was eine bessere Verteilung des Behandlungsmittels ermöglicht.According to a further preferred development, the spray head is designed to be rotatable relative to the treatment agent supply device, in particular about the longitudinal axis of the treatment agent supply device. This allows the spray head during the spraying of the treatment agent in the cavity to rotate, allowing a better distribution of the treatment agent.

Gemäß einer nicht erfindungsgemäßen Weiterbildung ist das Betätigungsmittel als mechanisches, hydraulisches, pneumatisches oder elektromechanisches Betätigungsmittel ausgebildet. Hierdurch wird ein komfortables automatisiertes Drehen des Sprühkopfs während des Versprühens des Behandlungsmittels ermöglicht.According to a development not according to the invention the actuating means is designed as a mechanical, hydraulic, pneumatic or electromechanical actuating means. This allows a comfortable automated turning of the spray head during the spraying of the treatment agent.

Gemäß einer weiteren bevorzugten Weiterbildung ist zumindest eine Behandlungsmittel-Austrittsöffnung der mehreren Behandlungsmittel-Austrittsöffnungen derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung ausgerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung ausströmende Behandlungsmittel den Sprühkopf in eine Rotation um beispielsweise die Längsachse der Behandlungsmittel-Zuführeinrichtung versetzt. Durch die Rotation des Sprühkopfs wird das Behandlungsmittel besser verteilt.According to a further preferred refinement, at least one treatment agent outlet opening of the plurality of treatment agent outlet openings is aligned with the longitudinal axis of the treatment agent supply device such that the treatment agent flowing out of the at least one treatment agent outlet opening causes the spray head to rotate about, for example, the longitudinal axis of the treatment agent supply device added. Due to the rotation of the spray head, the treatment agent is better distributed.

In den Figuren der Zeichnung bezeichnen gleiche Bezugszeichen gleiche oder funktionsgleiche Komponenten, soweit nichts Gegenteiliges angegeben ist.In the figures of the drawing, like reference characters designate like or functionally identical components, unless otherwise indicated.

Fig. 1 illustriert eine schematische, seitliche Teilansicht einer Sprühvorrichtung 1 gemäß einem nicht erfindungsgemäßen Ausführungsbeispiel. Wie in der Fig. 1 ersichtlich ist, weist die Sprühvorrichtung 1 einen Sprühkopf 2 auf, welcher als länglicher, insbesondere ovaler Rotationskörper mit einem runden Querschnitt ausgebildet ist. Es ist für den Fachmann offensichtlich, dass der Sprühkopf 2 auch als blockförmiger Körper mit einem ovalen, quadratischen, rechteckigen oder andersartigen Querschnitt ausgebildet sein kann. Über eine Behandlungsmittel-Zuführeinrichtung 3, welche in den Sprühkopf 1 mündet wird ein Behandlungsmittel dem Sprühkopf 2 zugeführt. Die Längsachse des Sprühkopfs 2 und der Behandlungsmittel-Zuführeinrichtung 3 sind gemäß des Ausführungsbeispiel in Fig. 1 deckungsgleich, die Längsachsen können jedoch auch einen Winkel einschließen oder parallel und beabstandet zueinander ausgerichtet sein. Fig. 1 illustrates a schematic, partial side view of a spray device 1 according to a non-inventive embodiment. Like in the Fig. 1 it can be seen, the spray device 1 to a spray head 2, which is designed as an elongated, in particular oval body of revolution with a round cross-section. It is obvious to a person skilled in the art that the spray head 2 can also be designed as a block-shaped body with an oval, square, rectangular or other cross-section. Via a treatment agent supply device 3, which opens into the spray head 1, a treatment agent is supplied to the spray head 2. The longitudinal axis of the spray head 2 and the treatment agent supply means 3 are according to the embodiment in Fig. 1 However, the longitudinal axes may also include an angle or be aligned parallel and spaced from each other.

Als Behandlungsmittel kommen beispielsweise Flüssigkeiten, Gase oder feine Feststoffe in Frage.Suitable treatment agents include, for example, liquids, gases or fine solids.

In die Oberfläche des Sprühkopfes 2 sind vorzugsweise mehrere Behandlungsmittel-Austrittsöffnungen 4, 5, 6 eingebracht, von denen in Fig. 1 der Übersichtlichkeit halber lediglich drei mit Bezugszeichen versehen sind. Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 können beliebig auf der Oberfläche des Sprühkopfs 2 angebracht und somit in unterschiedliche Sprührichtungen ausgerichtet sein. Durch die ovale Form des Sprühkopfs 2 ist es möglich, dass Behandlungsmittel-Austrittsöffnungen 4 auch in etwa entgegen der Richtung der Behandlungsmittel-Zuführeinrichtung 3 ausgerichtet sind und in diese Richtung das Behandlungsmittel sprühen. Durch diese Anordnung ist es vorteilhaft möglich, alle Bereiche und Hohlrauminnenwände eines nur durch eine kleine Öffnung zu erreichenden Hohlraums mit dem Behandlungsmittel zu beaufschlagen.In the surface of the spray head 2 preferably more treatment agent outlet openings 4, 5, 6 are introduced, of which in Fig. 1 for clarity, only three are provided with reference numerals. The treatment agent outlet openings 4, 5, 6 can be mounted as desired on the surface of the spray head 2 and thus aligned in different spraying directions. Due to the oval shape of the spray head 2, it is possible that treatment agent outlet openings 4 are also aligned approximately in the opposite direction of the treatment agent supply device 3 and spray the treatment agent in this direction. With this arrangement, it is advantageously possible to act on all areas and cavity inner walls of a cavity to be reached only through a small opening with the treatment agent.

Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 können als Bohrungen mit kreisförmigem Querschnitt aber auch als längliche Schlitze, rechteckförmige Durchbrüche oder ähnliches ausgeführt sein. Der Querschnitt der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 ist beliebig und hängt vom Anwendungsfall und der Art des Behandlungsmittels ab. Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 können senkrecht oder in einem Winkel zur Oberfläche des ovalen Drehkörpers des Sprühkopfs 2 angebracht sein. Auf dem Sprühkopf 2 können die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 gleichmäßig oder beliebig verteilt angeordnet sein, um Bereiche mit einem höheren Behandlungsmittel-Durchfluss und einem niedrigeren Behandlungsmittel-Durchfluss zu schaffen. Der Querschnitt der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 kann auf der Oberfläche des Sprühkopfs variieren. So können etwa in den Bereichen, welche am weitesten von der Behandlungsmittel-Zuführeinrichtung 3 entfernt sind und in denen daher der niedrigste Druck herrscht, größere Querschnitte vorgesehen werden zum gleichmäßigen Austritt des Behandlungsmittels über die gesamte Oberfläche des Sprühkopfs. Es können auch Bereiche des Sprühkopfes 2, welche besonders wichtige Stellen des Hohlrauminneren mit Behandlungsmittel versorgen sollen, im Falle des Verbrennungsmotors sind dies bei Viertaktmotoren die Ventilbereiche im Bereich der Zündkerzenbohrung oder bei Zweitaktmotoren die Einlass- und Auslassschlitze, mit einer erhöhten Dichte an Behandlungsmittel-Austrittsöffnungen 4, 5, 6 oder vergrößerten Querschnitten der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 versehen sein. Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 sind beispielsweise als wechselbare Düsen ausgebildet. Somit können die Querschnitte der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 flexibel ausgewählt und verstopfte Düsen ausgetauscht werden. Die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 können in ihrem Querschnitt beispielsweise einzeln, bereichsweise als auch in ihrer Gesamtheit verstellbar ausgebildet sein.The treatment agent outlet openings 4, 5, 6 can be designed as holes with a circular cross-section but also as elongated slots, rectangular openings or the like. The cross section of the treatment agent outlet openings 4, 5, 6 is arbitrary and depends on the application and the type of treatment agent. The treatment agent outlet openings 4, 5, 6 may be mounted perpendicular or at an angle to the surface of the oval rotating body of the spray head 2. On the spray head 2, the treatment agent outlet openings 4, 5, 6 may be arranged uniformly or distributed randomly to provide areas with a higher treatment agent flow rate and a lower treatment agent flow rate. The cross section of the treatment agent outlet openings 4, 5, 6 may vary on the surface of the spray head. For example, in the areas which are farthest from the treatment agent supply device 3 and in which therefore the lowest pressure prevails, larger cross sections may be provided for uniform discharge of the treatment agent over the entire area Surface of the spray head. It can also areas of the spray head 2, which should provide particularly important locations of the interior of the cavity with treatment agent, in the case of the internal combustion engine are the four valve engines, the valve areas in the spark plug hole or in two-stroke engines, the inlet and outlet slots, with an increased density of treatment agent outlet openings 4, 5, 6 or enlarged cross sections of the treatment agent outlet openings 4, 5, 6 be provided. The treatment agent outlet openings 4, 5, 6 are formed, for example, as replaceable nozzles. Thus, the cross sections of the treatment agent outlet openings 4, 5, 6 can be selected flexibly and blocked nozzles can be exchanged. The treatment agent outlet openings 4, 5, 6 may be designed to be adjustable in their cross section, for example, individually, in regions and in their entirety.

Der Sprühkopf 2 ist bevorzugt aus einem flexiblen oder schaumartigen Werkstoff, wie beispielsweise aus einem thermoplastischen Polyurethan (TPU), gebildet. Dadurch ist es möglich, den Sprühkopf 2 in zusammengedrücktem Zustand durch eine Öffnung, deren Querschnitt kleiner ist als der Querschnitt des Sprühkopfs 2 in nicht zusammengedrücktem Zustand, in den zu behandelnden Hohlraum einzuführen. Im Hohlraum entfaltet sich der Sprühkopf 2 durch die Elastizität des Materials oder durch den Druck mit dem das Behandlungsmittel zugeführt wird und das Hohlrauminnere kann wunschgemäß behandelt werden. Durch die Flexibilität des Materials des Sprühkopfs 2 kann dieser nach der Behandlung wieder durch die Zuführöffnung auf einfache Weise aus dem Hohlraum gezogen werden.The spray head 2 is preferably formed of a flexible or foam-like material, such as a thermoplastic polyurethane (TPU). This makes it possible to introduce the spray head 2 in the compressed state through an opening whose cross section is smaller than the cross section of the spray head 2 in the non-compressed state, in the cavity to be treated. In the cavity, the spray head 2 unfolds by the elasticity of the material or by the pressure with which the treatment agent is supplied and the interior of the cavity can be treated as desired. Due to the flexibility of the material of the spray head 2, it can be easily pulled out of the cavity again after the treatment through the feed opening.

Auch die Behandlungsmittel-Zuführeinrichtung 3 ist bevorzugt aus einem flexiblen Material gebildet. Im Gegensatz zu dem Material aus dem der Sprühkopf 2 gebildet ist, weist dieses Material jedoch vorzugsweise eine höhere Steifigkeit auf. Nach dem Biegen der Behandlungsmittel-Zuführeinrichtung 3 bleibt die Verformung erhalten. Zum einen kann der Sprühkopf 2 dann durch Biegungen eines Rohrsystems zum Behandlungsort geschoben werden. Zum anderen kann durch ein Vorbiegen der Behandlungsmittel-Zuführeinrichtung 3 die Position des Sprühkopfs 2 im Raum definiert werden. Vor dem Einführen des Sprühkopfs 2 in den zu behandelnden Hohlraum wird die Behandlungsmittel-Zuführeinrichtung 3 in der gewünschten Krümmung vorgebogen und der Sprühkopf 2 kann so innerhalb des Hohlraums hinter Hinterschnitten oder ähnlichem positioniert werden. Weiterhin kann die Behandlungsmittel-Zuführeinrichtung 3 auch aus einem Material gebildet sein, welches eine sehr geringe Steifigkeit aufweist, wie beispielsweise einem silikonartigen Material.The treatment agent supply device 3 is preferably formed from a flexible material. In contrast to the material from which the spray head 2 is formed, this material has but preferably a higher rigidity. After bending the treating agent supply means 3, the deformation is maintained. On the one hand, the spray head 2 can then be pushed through bends of a pipe system to the treatment location. On the other hand, the position of the spray head 2 in space can be defined by pre-bending the treatment agent supply device 3. Before introducing the spray head 2 into the cavity to be treated, the treating agent supply means 3 is pre-bent in the desired curvature and the spray head 2 can thus be positioned inside the cavity behind undercuts or the like. Furthermore, the treatment agent supply means 3 may also be formed of a material which has a very low rigidity, such as a silicone-like material.

Der Sprühkopf 2 ist vorzugsweise entweder als integraler Bestandteil der Behandlungsmittel-Zuführeinrichtung 3, beispielsweise in Form eines Spritzguss- oder Feingussteils, oder trennbar von der Behandlungsmittel-Zuführeinrichtung 3 ausgestaltet. Im zweiten Fall ist es möglich, den Sprühkopf als Ersatzteil für die Sprühvorrichtung 1 vorzusehen. Die Düsen der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 des Sprühkopfs sind ebenfalls austauschbar. Somit können verstopfte Düsen ausgetauscht werden oder Düsen mit verschiedenen Querschnitten eingesetzt werden.The spray head 2 is preferably designed either as an integral part of the treatment agent supply device 3, for example in the form of an injection molding or precision casting, or separable from the treatment agent supply device 3. In the second case, it is possible to provide the spray head as a spare part for the spray device 1. The nozzles of the treatment agent outlet openings 4, 5, 6 of the spray head are also exchangeable. Thus, clogged nozzles can be replaced or nozzles with different cross sections can be used.

Fig. 2 illustriert eine schematische, seitliche Teilansicht einer Sprühvorrichtung 1 gemäß einem nicht erfindungsgemäßen Ausführungsbeispiel. Im Unterschied zu dem Ausführungsbeispiel nach Fig. 1 ist der Sprühkopf 2 relativ zu der Behandlungsmittel-Zuführeinrichtung 3 um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 drehbar ausgebildet. Allerdings ist es für den Fachmann offensichtlich, dass auch Drehungen um andere Achsen vorstellbar und möglich sind. Fig. 2 illustrates a schematic, partial side view of a spray device 1 according to a non-inventive embodiment. In contrast to the embodiment according to Fig. 1 the spray head 2 is designed to be rotatable relative to the treatment agent supply device 3 about the longitudinal axis of the treatment agent supply device 3. However, it is obvious to the person skilled in the art that rotations about other axes are also conceivable and possible.

Gemäß dem vorliegenden Ausführungsbeispiel ist zumindest eine Behandlungsmittel-Austrittsöffnung 5 der mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung 3 ausgerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung 5 ausströmende Behandlungsmittel den Sprühkopf 2 in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 versetzt. Es ist somit eine optimierte Verteilung des Behandlungsmittels möglich. Die drehbare Verbindung zwischen dem Sprühkopf 2 und der Behandlungsmittel-Zuführeinrichtung 3 ist bevorzugt dicht gegen das verwendete Behandlungsmittel ausgestaltet, etwa mittels einer Gummi- oder Keramikdichtung. Zur Lagerung der drehbaren Verbindung sind kleine Wälzlager oder Gleitlager vorgesehen, welche beispielsweise integraler Bestandteil des Sprühkopfs 2 oder der Behandlungsmittel-Zuführeinrichtung sind. In Fig. 2 ist beispielhaft schematisch ein Gleitlager 16 dargestellt.According to the present exemplary embodiment, at least one treatment agent outlet opening 5 of the plurality of treatment agent outlet openings 4, 5, 6 is aligned with the longitudinal axis of the treatment agent supply device 3 such that the treatment agent flowing out of the at least one treatment agent outlet opening 5 causes the spray head 2 to rotate offset about the longitudinal axis of the treatment agent supply device 3. Thus, an optimized distribution of the treatment agent is possible. The rotatable connection between the spray head 2 and the treatment agent supply device 3 is preferably designed to be tight against the treatment agent used, for example by means of a rubber or ceramic seal. For the storage of the rotatable connection small rolling bearings or plain bearings are provided, which are for example an integral part of the spray head 2 or the treatment agent supply device. In Fig. 2 is exemplified schematically a plain bearing 16 is shown.

Fig. 3 illustriert eine Teilansicht einer Sprühvorrichtung 1 gemäß einem bevorzugten Ausführungsbeispiel der vorliegenden Erfindung. Die Behandlungsmittel-Zuführeinrichtung 3 ist hierbei in zwei voneinander getrennte Abschnitte 13 und 14 aufgeteilt. Der Abschnitt 14 ist vorzugsweise mit dem Sprühkopf 2 verbunden. Die Abschnitte 13 und 14 sind beispielsweise über eine Hülse 17 drehbar um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 miteinander verbunden. Dabei ist zumindest eine Behandlungsmittel-Austrittsöffnung 5 der mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung 3 ausgerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung 5 ausströmende Behandlungs-mittel den Sprühkopf 2 in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 versetzt. Der Sprühkopf 2 dreht sich somit aufgrund des austretenden Behandlungsmittels. Somit ist eine optimale Verteilung des Behandlungsmittels möglich. Der Sprühkopf 2 wird über das Einbringen einer Drehbewegung mittels eines Betätigungsmittels 15, welches mit dem Abschnitt 14 der Behandlungsmittel-Zuführeinrichtung 3 fest verbunden ist, rotiert. Die Länge des Abschnitts 14 ist für diesen Fall vorzugsweise derart zu wählen, dass das dem Sprühkopf 2 abgewandte Ende des Abschnitts 14 aus dem zu behandelnden Bereich herausragt. Das Betätigungsmittel 15 ist erfindungsgemäß als Handgriff ausgebildet. Weiterhin ist es möglich, aber von der Erfindung nicht vorgesehen, den Sprühkopf über eine entsprechende mechanische, hydraulische, pneumatische oder elektromechanische Vorrichtung, beispielsweise über einen Elektromotor, welche an dem Betätigungsmittel 15 angreift, rotierbar zu gestalten. Durch das Rotieren des Sprühkopfs 2 in dem zu behandelnden Bereich wird eine optimierte Verteilung des Behandlungsmittels gewährleistet. Die Verbindungshülse 17 ist bevorzugt dicht gegen das verwendete Behandlungsmittel ausgestaltet, beispielsweise mittels einer Gummi- oder Keramikdichtung. Zur Lagerung der Verbindungshülse 17 sind beispielsweise kleine Wälzlager oder Gleitlager vorgesehen, welche integraler Bestandteil eines der Abschnitte 13, 14 der Behandlungsmittel-Zuführeinrichtung 3 sein können. Fig. 3 illustrates a partial view of a spray device 1 according to a preferred embodiment of the present invention. The treatment agent supply device 3 is in this case divided into two separate sections 13 and 14. The section 14 is preferably connected to the spray head 2. The sections 13 and 14 are connected, for example via a sleeve 17 rotatable about the longitudinal axis of the treatment agent supply means 3 with each other. In this case, at least one treatment agent outlet opening 5 of the plurality of treatment agent outlet openings 4, 5, 6 aligned to the longitudinal axis of the treatment agent supply means 3, that the effluent from the at least one treatment agent outlet opening 5 treatment medium the spray head 2 in a rotation the longitudinal axis of the treatment agent supply device 3 is offset. The spray head 2 thus rotates due to the exiting treatment agent. Thus is an optimal distribution of the treatment agent possible. The spray head 2 is rotated via the introduction of a rotary movement by means of an actuating means 15 which is fixedly connected to the portion 14 of the treatment agent supply means 3. For this case, the length of the section 14 is preferably to be selected such that the end of the section 14 facing away from the spray head 2 projects out of the area to be treated. The actuating means 15 is designed according to the invention as a handle. Furthermore, it is possible, but not provided by the invention, to make the spray head rotatable via a corresponding mechanical, hydraulic, pneumatic or electromechanical device, for example via an electric motor which acts on the actuating means 15. By rotating the spray head 2 in the area to be treated, an optimized distribution of the treatment agent is ensured. The connecting sleeve 17 is preferably designed to be tight against the treatment agent used, for example by means of a rubber or ceramic seal. For the storage of the connecting sleeve 17 small rolling bearings or plain bearings are provided, for example, which may be an integral part of one of the sections 13, 14 of the treatment agent supply device 3.

Fig. 4 illustriert eine schematische Teilansicht einer Sprühvorrichtung 1 gemäß einem nicht erfindungsgemäßen Ausführungsbeispiel. Im Unterschied zu dem in Fig. 1 dargestellten Sprühkopf ist der Sprühkopf 2 des vorliegenden Ausführungsbeispiels in beispielsweise drei Segmente 7, 8, 9 aufgeteilt. Für den Fachmann ist es allerdings offensichtlich, dass der Sprühkopf 2 auch in weniger oder mehr als drei Segmente aufgeteilt werden kann. Die Segmente 7, 8, 9 sind bezüglich der Längsachse des Sprühkopfs 2 relativ zueinander verdrehbar. Durch Vorsehen von unterschiedlichen Querschnitten und Dichtenverteilungen der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 auf der Oberfläche des Sprühkopfs 2 kann die Menge an Behandlungs-mittel, welche in einer bestimmten Richtung austreten soll, definiert eingestellt werden. Dabei sind die mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 gemäß dem vorliegenden Ausführungsbeispiel derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung 3 ausgerichtet, dass das aus den mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 ausströmende Behandlungsmittel den Sprühkopf 2 in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 versetzt. Fig. 4 illustrates a schematic partial view of a spray device 1 according to a non-inventive embodiment. Unlike the in Fig. 1 spray head shown the spray head 2 of the present embodiment, for example, in three segments 7, 8, 9 divided. However, it will be apparent to those skilled in the art that the spray head 2 may be divided into fewer or more than three segments. The segments 7, 8, 9 are rotatable relative to each other with respect to the longitudinal axis of the spray head 2. By providing different cross-sections and density distributions of the treatment agent outlet openings 4, 5, 6 on the surface of the spray head 2, the amount of treatment agent, which is to emerge in a certain direction, can be set defined. In this case, the plurality of treatment agent outlet openings 4, 5, 6 are aligned according to the present embodiment to the longitudinal axis of the treatment agent supply means 3, that the effluent from the plurality of treatment agent outlet openings 4, 5, 6 effluent treating the spray head 2 in a rotation around the Longitudinal axis of the treatment agent supply device 3 offset.

Durch gegensätzliche Anordnung zumindest jeweils einer Behandlungsmittel-Austrittsöffnung 4, 5, 6 auf jeweils unterschiedlichen Segmenten rotieren die jeweiligen Segmente in gegensätzliche Richtungen.By opposing arrangement of at least one treatment agent outlet opening 4, 5, 6 on respectively different segments, the respective segments rotate in opposite directions.

Die Segmente 7, 8, 9 sind zueinander bevorzugt dicht gegen das Behandlungsmittel ausgebildet. Die Abdichtung kann beispielsweise über eine Gummi- oder Keramikdichtung erfolgen. Die Segmente 7, 8, 9 sind zueinander beispielsweise über Wälz- oder Gleitlager gelagert. Die Gleitlager sind dabei bevorzugt integraler Bestandteil eines der Segmente 7, 8, 9. Die Behandlungsmittel-Zuführeinrichtung 3 kann auch derart ausgestaltet sein, dass diese mehrere Einzelleitungen aufweist, welche zu den einzelnen Segmenten führen. Dadurch ist es möglich, einzelne Segmente 7, 8, 9 des Sprühkopfs 2 abzuschalten. Das Abschalten einzelner Segmente 7, 8, 9 kann beispielsweise durch Einbringen von Schiebern in einzelne Querschnitte einer mehrlumigen Behandlungsmittel-Zuführeinrichtung 3 oder Querschnittsverringerung durch Zusammendrücken einzelner Querschnitte der mehrlumigen Behandlungsmittel-Zuführeinrichtung erfolgen. Es kann somit beispielsweise eine Verteilung des Behandlungsmittels direkt nach oben, nach unten oder zur Seite durch Deaktivierung bestimmter Segmente verhindert werden.The segments 7, 8, 9 are preferably formed tightly against each other against the treatment agent. The seal can be done for example via a rubber or ceramic seal. The segments 7, 8, 9 are mounted to each other for example via rolling or plain bearings. The plain bearings are preferably an integral part of one of the segments 7, 8, 9. The treatment agent supply device 3 can also be designed such that it has a plurality of individual lines, which lead to the individual segments. This makes it possible to disconnect individual segments 7, 8, 9 of the spray head 2. The switching off of individual segments 7, 8, 9 can take place, for example, by introducing slides into individual cross-sections of a multi-lumen treatment agent supply device 3 or reducing the cross-section by compressing individual cross sections of the multi-lumen treatment agent supply device. Thus, for example, a distribution of the treatment agent directly up, down or to the side by deactivating certain segments can be prevented.

Fig. 5 illustriert ein weiteres nicht erfindungsgemäßes Ausführungsbeispiel der Sprühvorrichtung 1 in schematischer Teilansicht. Der Sprühkopf 2 ist hierbei als ein Bündel mehrerer Leitungen 10, 11, 12 ausgebildet, von denen in Fig. 5 der Übersichtlichkeit halber lediglich drei mit Bezugszeichen versehen sind. Jede der Leitungen 10, 11, 12 weist vorzugsweise zumindest eine Behandlungsmittel-Austrittsöffnung 4, 5, 6 auf. In Fig. 5 sind die Behandlungsmittel-Austrittsöffnung 4, 5, 6 beispielhaft an den Enden der Leitungen 10, 11, 12 dargestellt. Die Behandlungsmittel-Austrittsöffnung 4, 5, 6 können aber auch an den Mantelflächen der Leitungen 10, 11, 12 angeordnet sein. Fig. 5 illustrates a further non-inventive embodiment of the spray device 1 in a schematic partial view. The spray head 2 is in this case formed as a bundle of several lines 10, 11, 12, of which in Fig. 5 for clarity, only three are provided with reference numerals. Each of the lines 10, 11, 12 preferably has at least one treatment agent outlet opening 4, 5, 6. In Fig. 5 For example, the treatment agent outlet openings 4, 5, 6 are shown at the ends of the lines 10, 11, 12 by way of example. However, the treatment agent outlet opening 4, 5, 6 can also be arranged on the lateral surfaces of the lines 10, 11, 12.

Die Leitungen 10, 11, 12 sind bevorzugt aus einem flexiblen Material ausgebildet. Nach dem Verformen des Materials bleibt dieses vorzugsweise in der gewünschten Position. Durch das Verformen der einzelnen Leitungen 10, 11, 12 kann die Sprührichtung der Leitungen 10, 11, 12 eingestellt werden. Somit ist es möglich, die Sprührichtung und Sprühmenge in einer Richtung des Sprühkopfs 2 exakt zu definieren.The lines 10, 11, 12 are preferably formed of a flexible material. After deformation of the material, this preferably remains in the desired position. By deforming the individual lines 10, 11, 12, the spray direction of the lines 10, 11, 12 can be adjusted. Thus, it is possible to accurately define the spray direction and spray amount in a direction of the spray head 2.

Der Querschnitt der einzelnen Leitungen 10, 11, 12 wird vorzugsweise je nach Anwendungsfall und dem zu verwendenden Behandlungsmittel festgelegt. Innerhalb des Sprühkopfes 2 können Leitungen 10, 11, 12 mit verschiedenen Querschnitten und ebenso unterschiedliche Behandlungsmittel-Austrittsöffnung 4, 5, 6 verwendet werden, um unterschiedliche Durchflussmengen innerhalb des Sprühkopfs 2 zu realisieren. Die Form des Querschnitts der Leitungen 10, 11, 12 ist bevorzugt kreisförmig, kann aber auch jede Form, wie z.B. eine rechteckige Form annehmen. Wie bei den zuvor beschriebenen Ausführungsbeispielen bereits beschrieben, können die Querschnitte der Behandlungsmittel-Austrittsöffnungen 4, 5, 6 beliebig und die Behandlungsmittel-Austrittsöffnungen 4, 5, 6 als wechselbare oder als in ihrem Querschnitt verstellbare Düsen ausgebildet sein.The cross section of the individual lines 10, 11, 12 is preferably determined depending on the application and the treatment agent to be used. Within the spray head 2 lines 10, 11, 12 with different cross sections and equally different treatment agent outlet opening 4, 5, 6 are used to realize different flow rates within the spray head 2. The shape of the cross section of the lines 10, 11, 12 is preferably circular, but may also take any shape, such as a rectangular shape. As already described in the previously described exemplary embodiments, the cross sections of the treatment agent outlet openings 4, 5, 6 can be arbitrary and the treatment agent outlet openings 4, 5, 6 are designed as exchangeable or adjustable in their cross-section nozzles.

Fig. 6 illustriert in schematischer Teilansicht eine weitere nicht erfindungsgemäße Sprühvorrichtung 1. In diesem Ausführungsbeispiel ist der Sprühkopf 2 im Unterschied zu dem Ausführungsbeispiel nach Fig. 5 relativ zu der Behandlungsmittel-Zuführeinrichtung 3 um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3, drehbar ausgebildet. Allerdings ist es für den Fachmann offensichtlich, dass auch Drehungen um andere Achsen vorstellbar und möglich sind. Fig. 6 Illustrates a schematic partial view of another non-inventive spray device 1. In this embodiment, the spray head 2, in contrast to the embodiment according to Fig. 5 relative to the treatment agent supply means 3 about the longitudinal axis of the treatment agent supply means 3, rotatably formed. However, it is obvious to the person skilled in the art that rotations about other axes are also conceivable and possible.

Gemäß dem vorliegenden Ausführungsbeispiel ist zumindest eine Behandlungsmittel-Austrittsöffnung 5 der mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung 3 aus-gerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung 5 ausströmende Behandlungsmittel den Sprühkopf 2 in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 versetzt. Es ist somit eine optimierte Verteilung des Behandlungsmittels gewährleistet. Die drehbare Verbindung zwischen dem Sprühkopf 2 und der Behandlungsmittel-Zuführeinrichtung 3 ist bevorzugt dicht gegen das verwendete Behandlungsmittel ausgestaltet, etwa mittels einer Gummi- oder Keramikdichtung. Zur Lagerung der drehbaren Verbindung sind kleine Wälzlager oder Gleitlager vorgesehen, welche integraler Bestandteil des Sprühkopfs 2 oder der Behandlungsmittel-Zuführeinrichtung sein können. In Fig. 6 ist beispielhaft ein Gleitlager 16 schematisch dargestellt.According to the present exemplary embodiment, at least one treatment agent outlet opening 5 of the plurality of treatment agent outlet openings 4, 5, 6 directed to the longitudinal axis of the treatment agent supply means 3 so that the effluent from the at least one treatment agent outlet opening 5 treatment means the spray head 2 in a rotation about the longitudinal axis of the treatment agent supply means 3 is added. It is thus ensured an optimized distribution of the treatment agent. The rotatable connection between the spray head 2 and the treatment agent supply device 3 is preferably designed to be tight against the treatment agent used, for example by means of a rubber or ceramic seal. For mounting the rotatable connection small rolling bearings or plain bearings are provided, which may be an integral part of the spray head 2 or the treatment agent supply device. In Fig. 6 For example, a plain bearing 16 is shown schematically.

Fig. 7 illustriert in schematischer Teilansicht eine Sprühvorrichtung 1 gemäß einem weiteren bevorzugten Ausführungsbeispiel der vorliegenden Erfindung. Die Behandlungsmittel-Zuführeinrichtung 3 ist hierbei in zwei separate und voneinander getrennte Abschnitte 13 und 14 aufgeteilt. Der Abschnitt 14 ist mit dem Sprühkopf 2 verbunden. Die Abschnitte 13 und 14 sind über eine Hülse 17 drehbar um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 miteinander verbunden. Fig. 7 Illustrates a schematic partial view of a spray device 1 according to another preferred embodiment of the present invention. The treatment agent supply device 3 is in this case in two separate and from each other divided sections 13 and 14. The section 14 is connected to the spray head 2. The sections 13 and 14 are connected to each other via a sleeve 17 rotatable about the longitudinal axis of the treatment agent supply device 3.

Gemäß dem vorliegenden Ausführungsbeispiel ist zumindest eine Behandlungsmittel-Austrittsöffnung 5 der mehreren Behandlungsmittel-Austrittsöffnungen 4, 5, 6 derart zu der Längsachse der Behandlungsmittel-Zuführeinrichtung 3 aus-gerichtet, dass das aus der zumindest einen Behandlungsmittel-Austrittsöffnung 5 ausströmende Behandlungsmittel den Sprühkopf 2 in eine Rotation um die Längsachse der Behandlungsmittel-Zuführeinrichtung 3 versetzt. Der Sprühkopf 2 dreht sich somit aufgrund des austretenden Behandlungsmittels relativ zu dem Abschnitt 13 der Behandlungsmittel-Zuführeinrichtung 3. Somit ist eine optimale Verteilung des Behandlungsmittels möglich. Der Sprühkopf 2 wird über das Einbringen einer Drehbewegung mittels eines Betätigungsmittels 15, welches mit dem Abschnitt 14 der Behandlungsmittel-Zuführeinrichtung 3 fest verbunden ist, rotiert. Die Länge des Abschnitts 14 ist in diesem Fall derart zu wählen, dass das dem Sprühkopf 2 abgewandte Ende des Abschnitts 14 aus dem zu behandelnden Bereich herausragt. Das Betätigungsmittel 15 ist erfindungsgemäß als Handgriff ausgebildet. Weiterhin ist es möglich, aber von der Erfindung nicht vorgesehen, den Sprühkopf über eine entsprechende mechanische, hydraulische, pneumatische oder elektromechanische Vorrichtung, beispielsweise über einen Elektromotor, welche an dem Betätigungsmittel 15 angreift, rotierbar zu gestalten. Durch das Rotieren des Sprühkopfs 2 in dem zu behandelnden Bereich wird eine optimierte Verteilung des Behandlungsmittels gewährleistet.According to the present exemplary embodiment, at least one treatment agent outlet opening 5 of the plurality of treatment agent outlet openings 4, 5, 6 directed to the longitudinal axis of the treatment agent supply means 3 so that the effluent from the at least one treatment agent outlet opening 5 treatment means the spray head 2 in a rotation about the longitudinal axis of the treatment agent supply means 3 is added. The spray head 2 thus rotates relative to the portion 13 of the treatment agent supply means 3 due to the exiting treatment agent. Thus, an optimal distribution of the treatment agent is possible. The spray head 2 is rotated via the introduction of a rotary movement by means of an actuating means 15 which is fixedly connected to the portion 14 of the treatment agent supply means 3. The length of the portion 14 is to be selected in this case such that the spray head 2 facing away from the end of the portion 14 protrudes from the area to be treated. The actuating means 15 is designed according to the invention as a handle. Furthermore, it is possible, but not provided by the invention, to make the spray head rotatable via a corresponding mechanical, hydraulic, pneumatic or electromechanical device, for example via an electric motor which acts on the actuating means 15. By rotating the spray head 2 in the area to be treated, an optimized distribution of the treatment agent is ensured.

Die Verbindungshülse 17 ist bevorzugt dicht gegen das verwendete Behandlungsmittel ausgestaltet, beispielsweise mittels einer Gummi- oder Keramikdichtung. Zur Lagerung der Verbindungshülse 17 sind beispielsweise kleine Wälzlager oder Gleitlager vorgesehen, welche integraler Bestandteil eines der Abschnitte 13, 14 der Behandlungsmittel-Zuführeinrichtung 3 sind.The connecting sleeve 17 is preferably designed to be tight against the treatment agent used, for example by means of a rubber or ceramic seal. For the storage of the connecting sleeve 17 small rolling bearings or plain bearings are provided, for example, which are an integral part of one of the sections 13, 14 of the treatment agent supply device 3.
