Description

Die Erfindung betrifft Spritzpistolen, beiThe invention relates to spray guns

denen auf den ausgesandten Flüssigkeitsstrahl zwei zusätzliche Luftströme einwirken, um den an sich infolge der Form der Düsen runden Strahl abzuflachen.which act on the emitted liquid jet two additional air currents in order to to flatten the jet, which is round as a result of the shape of the nozzles.

Es sind bereits Spritzpistolen bekannt, bei denen auf den eigentlichen Düsenkörper eine Art Kappe aufgeschraubt ist, die mit Bohrungen für die zusätzlichen Luftströme versehen ίο ist, und deren Bohrungen beim Verdrehen der Kappe mit entsprechenden Bohrungen in dem Düsenkörper in Verbindung gebracht werden, so daß dann Luft durch die Bohrungen der Kappe ausströmt. .There are already spray guns known in which one on the actual nozzle body Kind of cap is screwed on, which is provided with holes for the additional air flows ίο is, and their holes when turning the cap with corresponding holes in the Nozzle body are brought into connection, so that then air through the bores of the Cap flows out. .

Bei anderen bekannten Spritzpistolen, die ebenfalls eine mittels Verschraubungen gehaltene Kappe aufweisen, kann die Kappe nach Lösen der Verschraubung verstellt werden, um die Ebene des abgeflachten Strahls zu verändern.In other known spray guns, which are also held by means of screw connections Have cap, the cap can be adjusted after loosening the screw connection, to change the plane of the flattened ray.

Gemäß der Erfindung ist die Luftdüse der Spritzpistole mit einem konischen Ansatz versehen, auf dessen konische Fläche die innen entsprechend konisch ausgeführte Kappe durch Wirkung einer Feder gedrückt wird.According to the invention, the air nozzle of the spray gun is provided with a conical extension, on the conical surface of which the internally correspondingly conical cap is pressed by the action of a spring.

Eine solche Anordnung besitzt gegenüberSuch an arrangement possesses opposite

den bekannten Ausführungen den Vorteil, daß die Kappe während des Arbeitens mit der Spritzpistole leicht und bequem von Hand verstellbar ist.the known designs have the advantage that the cap while working with the Spray gun is easily and conveniently adjustable by hand.

Auf der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Two exemplary embodiments of the invention are shown in the drawing.

Abb. ι zeigt einen Längsschnitt durch den Düsenkörper einer Spritzpistole, Abb. 2 einen Querschnitt nach der Linie a-a der Abb. i,Fig. Ι shows a longitudinal section through the nozzle body of a spray gun, Fig. 2 shows a cross section along the line aa of Fig. I,

Abb. 3 eine andere Ausführungsform. Der Pistolenkörper 1 trägt eine Luftdüse 2, die einen konischen Ansatz 2a trägt, auf dessen konischer Fläche eine Kappe 3 drehbar angeordnet ist, die unter Wirkung einer Feder 4 steht. ■Fig. 3 shows another embodiment. The gun body 1 carries a nozzle 2, which carries a conical projection 2 a, a cap 3 rotatably mounted on its conical surface which is under the action of a spring. 4 ■

Die Düse 2 ist senkrecht zu ihrer Achse mit einer am Rand erweiterten Bohrung 5 versehen, durch die Druckluft in zwei Bohrungen 6, & strömen kann, die in zwei diametral gegenüberliegenden Armen der Kappe 3 vorgesehen sind (Abb. 1). In dieser Stellung zerstäubt der Luftstrahl aus der Düse 2 die Flüssigkeit aus der Düse 9, während die in einem Punkt zusammentreffenden Lüftströme aus den Bohrungen 6, 6' den aus der Düse 2 kommenden runden Strahl flach gestalten. The nozzle 2 is provided, perpendicular to its axis, with a bore 5 widened at the edge, through which compressed air can flow in two bores 6, & , which are provided in two diametrically opposite arms of the cap 3 (Fig. 1). In this position, the air jet from the nozzle 2 atomizes the liquid from the nozzle 9, while the air currents from the bores 6, 6 'which meet at one point make the round jet coming from the nozzle 2 flat.

Wird die Kappe 3 beispielsweise durch den Handgriff 7 gedreht, so wird ebenfalls die Ebene des flachen Strahls gedreht, bis die Bohrungen 6, 6' durch die vollen Teile 8, 8' der Düse 2 überdeckt werden. Dann wird der gewöhnliche runde Strahl erhalten. Man kann die Lage der Ebene des flachen Strahles noch weiter ändern, indem man die Düse 2 in bezug auf den Pistolenkörper verdreht. Vorteilhafterweise wird die Stellung der Düse außen durch ein Merkzeichen sichtbar gemacht. If the cap 3 is rotated for example by the handle 7, the Plane of the flat beam rotated until the holes 6, 6 'through the full parts 8, 8' the nozzle 2 are covered. Then the ordinary round beam is obtained. Man can change the position of the plane of the flat jet even further by moving the nozzle 2 twisted with respect to the gun body. Advantageously, the position of the nozzle made visible on the outside by a mark.

Die Veränderung der Ebene des flachen Strahls ist durch die Düse 9 begrenzt, gegen die die Arme der Kappe 3 stoßen. Wenn es erwünscht ist, die Kappe 3 in jeder Richtung einstellen zu können/ so wird vorteilhafterweise die zu zerstäubende Flüssigkeit in der Mittelachse der Düse 2 durch ein Rohr 9' zugeführt (Abb. 3). Die Anordnung der übrigen Teile bleibt dabei die gleiche.The change in the plane of the flat jet is limited by the nozzle 9, against which abut the arms of the cap 3. If desired, the cap 3 in any direction to be able to adjust / so is advantageously the liquid to be atomized in the Central axis of the nozzle 2 fed through a pipe 9 '(Fig. 3). The arrangement of the rest Parts remain the same.

Die Anordnung kann auch umgekehrt so getroffen werden, daß die Kappe 3 fest und die Düse mit dem konischen Ansatz 2" drehbar angeordnet ist. Die zusätzlichen Luftstrahlen brauchen nicht symmetrisch zueinander zu liegen und nicht paarweise angeordnet zu sein, sondern können in verschiedener Art vorgesehen- werden, um besondere gewünschte Wirkungen zu erzielen. The arrangement can also be reversed so that the cap 3 is fixed and the nozzle with the conical extension 2 "is rotatably arranged. The additional air jets do not need to be symmetrical to one another and not be arranged in pairs, but can be provided in various ways. to achieve particular desired effects.
