F i g. 1 und 2 zeigen im Längs- und Querschnitt eine \usführungsform, bei der die Spitze der olivenförmigen Masse abgestumpft ist;F i g. 1 and 2 show in longitudinal and cross-section an embodiment in which the tip of the olive-shaped Mass is blunted;
F i g. 3 und 4 zeigen entsprechend den F i g. 1 und 2 eine weitere Ausführungsform mit einem einstellbaren Schlitz.F i g. 3 and 4 show corresponding to FIGS. 1 and 2 a further embodiment with an adjustable Slot.
In den verschiedenen Figuren dient das Treibmittelrohr 1 für das Treibmittel, das in den vorgesehenen Beispielen aus Luft besteht. Am Auslaßende 2 des Treibmittelrohres 1 ist koaxial hierzu ein allgemein olivenförmiger Leitkörper 3 vorgesehen, dessen Spitze 4 abgewandt von dem Rohrende liegt und dessen Hauptquerschnitt im wesentlichtn in der Ebene der Auslaßöffnung 2 des Treibmittelrohres 1 liegt. Dieser Leitkörper 3 wird durch dünne Träger in seiner Lage gehalten. Der Leitkörper 3 ist nach seiner Rückseite mit einem zentralen Durchlaßkanal 6 versehen, der mit Innengewinde versehen und auf das Zuführrohr 7 aufgeschraubt ist, das mit einem nicht dargestellten Behälter für das zu versprühende Strömungsmittel, im vorliegenden Beispiel Wasser, in Verbindung steht.In the various figures, the propellant tube 1 is used for the propellant that is in the intended Examples consists of air. At the outlet end 2 of the propellant tube 1 is a general coaxial therewith olive-shaped guide body 3 is provided, the tip 4 of which is facing away from the pipe end and the main cross-section of which is essentially in the plane of the outlet opening 2 of the propellant tube 1 located. This guide body 3 is held in place by thin supports. The guide body 3 is after his Rear side provided with a central passage 6, which is provided with an internal thread and on the feed pipe 7 is screwed on, with a container, not shown, for the to be sprayed Fluid, in the present example water, is in communication.
Bei der Ausführungsform nach F i g. 1 und 2 ist der Durchlaßkanal 6 axial durch den Kanal 10 über die ganze Länge der olivenförmigen Masse ausgedehnt. Die vordere Spitze des olivenförmigen Masse-Leitkörpers 3 ist abgestumpft, so daß eine napfförmige Ausnehmung mit flachem Boden mit nach außen sich erweiternden Seitenwänden 12 gebildet wird. Die Axiallänge des abgestumpften Teiles ist als Funktion der Drücke des Treibmittels und des getriebenen Strömungsmittels, der Durchmesser des Treibmilielrohres 1 und der Kanäle 6 und 10 gewählt. Es wurde festgestellt, daß das aus dem Zuführrohr 7 ankommende Wasser in dem ganzen Umgebungsraum von der imaginären Spitze der olivenförmigen Leitkörper 3 versprüht wird.In the embodiment according to FIG. 1 and 2, the passage 6 is axially through the passage 10 across extended the entire length of the olive-shaped mass. The front tip of the olive-shaped mass guide 3 is truncated, so that a cup-shaped recess with a flat bottom with after outside expanding side walls 12 is formed. The axial length of the truncated part is as Function of the pressures of the propellant and the driven fluid, the diameter of the propellant tube 1 and channels 6 and 10 are selected. It was found that the incoming from the feed pipe 7 Water in the whole surrounding space from the imaginary tip of the olive-shaped guide body 3 is sprayed.
Bei der Ausfüh.ungsform nach Fig.3 und4 ist der Leitkörper 3 in zwei Bauteile zerlegt. Das erste Teil ist die Basis 13 mit einer napfförmigen Vorderseite mit flachem Boden, deren Seitenwand 13' unge-In the embodiment according to Fig. 3 and 4 is the guide body 3 is broken down into two components. The first part is the base 13 with a cup-shaped front with a flat bottom, the side wall 13 'of which

Das Zuführrohr 7 besitzt an seinem Ende ein Gewinde zur Aufnahme des mit Gewinde versehenen Durchlaßkanals 6, der längs der Achse der Basis 13 verläuft, und zwischen diesen Teilenalmost in the plane of the outlet 2 of the propellant pipe 1. The feed pipe 7 has on his End of a thread for receiving the threaded passage channel 6, which runs along the axis the base 13 extends, and between these parts

Das zweite Teil ist ein Körper 15 mit olivenförmigera seal can be provided. The feed pipe? is also more radial with a certain number Openings 14 are provided which allow the fluid to flow into the cup-shaped part of the base 13. The second part is a body 15 with an olive-shaped
Spitze und einer axialen Gewindebohrung mit einem blinden Ende 16. Das Gewinde ist komplementär demjenigen auf dem Zuführrohr 7, und die rückwärtige Fläche des Körners 15 ist so geformt, daß eine Seitenwand 17 parallel der Seitenwand 13' des napfförmigen Teiles der Basis gebildet wird.Tip and an axial threaded hole with a blind end 16. The thread is complementary that on the feed tube 7, and the rear surface of the grain 15 is shaped so that a Side wall 17 is formed parallel to the side wall 13 'of the cup-shaped part of the base.
