4. The cartridge system according to claim 3 , wherein the rod is arranged between the at least two cartridges.

5. The cartridge system according to claim 3 , wherein the rod is arrange in the open space formed between the at least two.

6. The cartridge system according to claim 3 , wherein the rod is arranged parallel to the feed plungers and fixedly connected to the feed plungers through at least one fin or plate.

7. The cartridge system according to claim 1 , wherein the valve is configured such that, with the valve located in the open position, at least one fluid-tight connection from the at least one opening in each cartridge head to the at least one passage of the valve is provided.

8. The cartridge system according to claim 1 , wherein a connector is arranged on the valve, wherein the connector comprises a fastening means for fastening the dispensing tube, the passage of the valve extends through the connector, and the outlet opening of the valve is arranged on the connector.

9. The cartridge system according to claim 8 , wherein the fastening means is an external thread.

10. The cartridge system according to claim 8 , wherein the dispensing tube comprises a fastening means through which the dispensing tube is connected to the fastening means of the connector in a detachable manner or through which the dispensing tube is connected to the valve in a fixed manner.

11. The cartridge system according to claim 1 , wherein the dispensing tube commences on the outlet opening of the valve and extends the passage to a dispensing tube tip.

12. The cartridge system according to claim 1 , wherein the dispensing tube comprises a static mixer.

13. The cartridge system according to claim 1 , wherein the valve, located in the open position or in the closed position, is arranged in a press-fit manner over the at least one opening in each cartridge head and closes the at least one opening in each cartridge head in a sealed manner when the valve is located in the dosed position or connects the at least one opening in each cartridge head in a sealed manner to the passage of the valve when the valve is located in the open position.

14. The cartridge system according to claim 1 , wherein the at least two cartridges are arranged to be parallel with respect to each other.

15. The cartridge system according to claim 14 , wherein the at least one passage in the valve connects the openings of the at least two cartridges to the outlet opening of the valve when the valve is located in the open position.

16. The cartridge system according to claim 1 , wherein the valve is cylinder-shaped, or takes a shape of a cylinder with an elliptical base or a shape of a section of a cylinder.
