Die Mischkammer besteht aus einem meist kotv_8chen Rohr mit festengebrachten Prellkörpern, durch welchee die beiden Komponenten gefördert werden. Um eine gute Mischung zu erzielen, nüssen die Prallkörper oder Prallflächen sehr eng gestellt werden, so daß zum Durchströmen hohe Drücke erforderlich sind.The cartridges are arranged in parallel and are filled into a common static mixing chamber with outlet by two mechanically driven, synchronously running pistons. If the mixing ratio of the two components is not normally 1, the cartridge is provided with a small, smaller volume and a correspondingly smaller diameter. The mixing chamber consists of a mostly cylindrical tube with fixed impact bodies through which the two components are conveyed. In order to achieve a good mixture, the impact bodies or impact surfaces must be placed very close together, so that high pressures are required for the fluid to flow through.
Das Gerät nach der vorliegenden Erfindung benutzt zwei gleich große, paralell zueinanderliegende Kartuschen, welche durch zwei mit unterschiedlicher Geschwindigkeit laufende, hydraulisch betätigte Kolben in eine gemeinsame Mischkammer entleert werden.

The membrane 2o with plate 21 and spring 22 is protected from external damage by a housing cover 23.
Der Steg 24 im Gehäuse 2 trennt die Druckseite des Kolbens 4 von der drucklosen Seite 26 dieses Kolbens.The web 24 in the housing 2 separates the pressure side of the piston 4 from the pressure-free side 26 of this piston.
Das Saugventil 27 besteht eu6 einem gerollten dünnen, elastischen, offenen Stehlblechring mit geringer Vorspannung, ähnlich einem Kolbenring an der Wand anliegend. Das eine Ende 28 ist im Gehäuse befestigt, das lose Ende 29 liegt vor der Steuerbohrung 18 (Figur 3).The suction valve 27 consists of a rolled, thin, elastic, open steel sheet ring with a low preload, similar to a piston ring resting against the wall. One end 28 is fastened in the housing, the loose end 29 is in front of the control bore 18 (Figure 3).

Am Gelenkpunkt 32 des Handhebels Io ist die Verbindungsstenge 33 befestigt. Das andere Ende 34 dieser Verbindungsstange ist gabelförmig ausgebildet und greift in den Hals 35 der Verschiebewelle 36 der Mischkammer 37 ein. In die Verschiebewelle 36 ist eine schräge Nute 38 eingearbeitet, welche sich mit einem in der Mischkammer 37 befestigten Stift 39 im Eingriff befindet. Mit der Verschiebewelle 36 fest verbunden ist ein Flügelrad 4o,The connecting rod 33 is attached to the articulation point 32 of the hand lever 10. The other end 34 of this connecting rod is fork-shaped and engages in the neck 35 of the displacement shaft 36 of the mixing chamber 37. An oblique groove 38 is machined into the displacement shaft 36, which is in engagement with a pin 39 attached in the mixing chamber 37. An impeller 40 is firmly connected to the displacement shaft 36.

dem geringeren Mischungsanteil. Hier wirkt der Handhebel Io nicht mehr direkt auf den Kolben 42, sondern unter Zwischenschaltung eines Hebele 43. Dieser Hebel sitzt mit seiner Bohrung auf dem Zapfen 44 des Exzenters 45 und wird durch die Feder 46 über den Kolben 47 mit seiner Nass 48 gegen den H&ndhebel Io gedruckt, üer Exzenter 45 ist mit seiner Welle 49 drehbar im Gehäuse 2 yöläyört und kann in jeder Lace fixiert werden.the lower proportion of mixture. Here the hand lever Io no longer acts directly on the piston 42, but with the interposition of a lever 43. This lever sits with its bore on the pin 44 of the eccentric 45 and is pressed by the spring 46 via the piston 47 with its shaft 48 against the hand lever Io. The eccentric 45 is rotatably mounted in the housing 2 with its shaft 49 and can be fixed in any position.
In der gezeichneten Lage befindet sich die Nase 48 im geringsten Abstand von der Achse 11 des Handhebels lo, der Kolben 47 macht den geringsten Hub. Durch Drehung des Exzenters 45 um 18o° wird der Hub des Kolbens 47 am größten.In the position shown, the nose 48 is at the shortest distance from the axis 11 of the hand lever 10, and the piston 47 makes the shortest stroke. By rotating the eccentric 45 by 180°, the stroke of the piston 47 becomes the greatest.

Figur 5 zeigt die Vorderansicht der Dosierpistole. 1 ist die strichpunktiert gezeichnete Kartusche für die Komponente mit dem größeren Mischungsanteil. 41 ist die strichpunktiert gezeichnete Kartusche für die Komponente mit dem geringeren Mischungsenteil. Figure 5 shows the front view of the dispensing gun. 1 is the dot-dash cartridge for the component with the larger mixing proportion. 41 is the dot-dash cartridge for the component with the smaller mixing proportion.
Die beiden Kartuschen 1 und 41 werden nach dem Offnen durch Anschneiden der Gewindespitze in die Mischkammer 37 eingeschraubt und gemeinsam in die Dosierpistole eingelegt und durch die Abklappen der Abdeckhaube 5o fixiert. Sollte die Druckplatte 8 zu weit ausgefahren sein, kann durch Lüften (Herausdrücken) des Handhebels 10 der Steuerkolben 18 in des Gehäuse 2 gedrückt werden, wodurch eine Verbindung der Druckseite 25 mit der drucklosen Seite 26 über die Steuerbohrungen und 18 erfolgt. Detzt kann die Druckplatte 8 mit Kolbenstange 6 und Kolben 4 in das Gehäuse verschoben werden. Das gleiche gilt auch für die Druckplatte auf der Seite der Kartusche für den geringeren Mischungsanteil.After opening, the two cartridges 1 and 41 are screwed into the mixing chamber 37 by cutting the thread tip and are placed together in the dosing gun and secured by folding down the cover 5o. If the pressure plate 8 is extended too far, the control piston 18 can be pressed into the housing 2 by venting (pushing out) the hand lever 10, which connects the pressure side 25 with the pressure-free side 26 via the control holes 1 and 18. The pressure plate 8 with piston rod 6 and piston 4 can then be pushed into the housing. The same applies to the pressure plate on the side of the cartridge for the lower mixture proportion.
Durch die Betätigung des Handhebels Io wird der Kolben 12 in das Gehäuse 2 gedrückt und verdrängt die Hydraulikflüssigkeit aus dem Raum über die Bohrung 31, das Druckventil 3o in den Druckraum 25. Dadurch wird der Kolben 4 mit Kolbenstange 6 und Druckplatte 8 aus dem Gehäuse bewegt und fördert die Mischungskomponente mit dem größeren Mischungsanteil aus der Kartusche in die Mischkammer 37. Nach dem Loslassen des Handhebels Io wird dieser wieder durch die Feder über den Kolben 12 in die Ausgangslage zurückgebracht. Dabei wird durch den Kolben 12 über Idas Saugventil 27 und die Bohrung 18 Hydraulikflüssigkeit aus dem Raum 26 in den Raum 53 gefördert. Parallel dazu verläuft dieser Vorgang inBy operating the hand lever Io, the piston 12 is pressed into the housing 2 and displaces the hydraulic fluid from the chamber via the bore 31, the pressure valve 3o into the pressure chamber 25. This moves the piston 4 with piston rod 6 and pressure plate 8 out of the housing and conveys the mixture component with the larger mixture portion from the cartridge into the mixing chamber 37. After releasing the hand lever Io, it is returned to the starting position by the spring via the piston 12. In the process, hydraulic fluid is conveyed by the piston 12 via I, the suction valve 27 and the bore 18 from the chamber 26 into the chamber 53. This process takes place in parallel in

gleicher Weise euch für die Seite mit der Kartusche 41, nur mit dem Unterschied, daß der Kolbenhub des Kolbens 47 über den Hebel und den Exzenter 45 dem verlangten Mischungsverhältnis angepaßt werden kann.The same applies to the side with the cartridge 41, with the only difference being that the piston stroke of the piston 47 can be adjusted to the required mixing ratio via the lever and the eccentric 45.
Gleichzeitig mit der Betätigung des Handhebels wird über din Verbindungsstange 33 die Verschiebewelle 36 mit dem Flügelrad 4o in den Mischkammern 37 hin und her bewegt. Durch die schräge Nut 38 in der Verschiebewelle 36 und dem in der Mischkammer 37 befestigten Stift 39 wird zusätzlich eine Drehbewegung des Flügelrades erreicht. Durch diese kombinierte Dreh-und Schubbewegung wird eine besonders gute Mischung erreicht. An Stelle von Nut 38 und Stift 39 kann auch ein Steilgewinde verwendet werden.At the same time as the hand lever is operated, the displacement shaft 36 with the impeller 40 is moved back and forth in the mixing chambers 37 via the connecting rod 33. The oblique groove 38 in the displacement shaft 36 and the pin 39 fastened in the mixing chamber 37 also cause the impeller to rotate. This combined rotation and thrust movement achieves a particularly good mix. Instead of the groove 38 and pin 39, a steep thread can also be used.
Diese Erfindung ist nicht nur auf die Anwendung von 2 Komponenten beschränkt; man ke:;n auch 3 oder mehr Komponenten zu einem Block zusammenfassen. Besonders vorteilhaft ist hier die Anwendung der hydraulischen Kraftübertragung. Oe nach Verwendungszweck kann der Kolbenhub eines oder mehrerer Kolben stufenlos einstellbar sein.This invention is not limited to the use of just 2 components; 3 or more components can also be combined into one block. The use of hydraulic power transmission is particularly advantageous here. Depending on the intended use, the piston stroke of one or more pistons can be infinitely adjustable.
