3. The two-component dispenser in accordance with claim 1 , wherein the first and second drive plate assemblies each comprise two plates separated by a spacer, or the first and second drive plate assemblies are pre-biased by retaining devices against the dispensing direction.

4. The two-component dispenser in accordance with claim 1 , wherein the two-component dispenser is capable of adopting a neutral state by moving a carriage relative to the actuation mechanism to engage the first and second drive plate assemblies and in the neutral state the first and second drive plate assemblies are respectively arranged releasable with respect to the first and second push rods.

5. The two-component dispenser in accordance with claim 1 , wherein the actuation mechanism is arranged in a first plane comprising the first and second push rods.

6. The two-component dispenser in accordance with claim 5 , wherein the actuation mechanism is arranged in a second plane or symmetrically with respect to the second plane, the second plane being arranged transversely with respect to the first and second push rods and centrally between the first and second push rods.

7. The two-component dispenser in accordance with claim 1 , wherein the actuation mechanism comprises a driving shaft and at least one push member arranged at or integrally formed with the driving shaft, the driving shaft configured to be moved to and fro in an at least substantially linear manner between the plurality of dispensing positions and the release position in parallel to the first and second push rods, and the at least one push member configured to engage the first and second drive plate assemblies in the plurality of dispensing positions of the actuation mechanism.

8. The two-component dispenser in accordance with claim 7 , wherein the at least one push member is a push plate.

9. The two-component dispenser in accordance with claim 1 , wherein, when the actuation mechanism is in the release position, first and second brake plates respectively lock the first and second push rods with the first and second brake plates and fix the position of the first and second push rods.

10. The two-component dispenser in accordance with claim 9 , wherein the two-component dispenser is capable of adopting a neutral state by moving a carriage relative to the actuation mechanism to engage the first and second brake plates and in the neutral state the first and second brake plates are respectively arranged releasable with respect to the first and second push rods.

11. The two-component dispenser in accordance with claim 1 , wherein the first and second push rods are guided in front and rear guides and the actuation mechanism is arranged between the front and rear guides.

12. The two-component dispenser in accordance with claim 11 , wherein at least one of the rear guides is a guide for the actuation mechanism.

13. The two-component dispenser in accordance with claim 1 , wherein the actuation mechanism is actuated by a trigger lever connected thereto.

14. The two-component dispenser in accordance with claim 13 , wherein the trigger lever comprises a yoke with the first and second push rods being guided through an opening of the yoke of the trigger lever.

15. The two-component dispenser in accordance with claim 13 , wherein the trigger lever is connected to the actuation mechanism via a reducer transmission.

16. The two-component dispenser in accordance with claim 15 , wherein the actuation mechanism is arranged in a first plane comprising the first and second push rods, and the trigger lever or the reducer transmission are arranged in or symmetrically with respect to the first plane.

17. The two-component dispenser in accordance with claim 15 , wherein the trigger lever or the reducer transmission is mounted in a housing of the two-component dispenser at at least one pivot point.

18. The two-component dispenser in accordance with claim 15 , wherein the reducer transmission comprises a connection part and a gear arm arrangement.

19. The two-component dispenser in accordance with claim 18 , wherein the gear arm arrangement comprises a yoke with the first push rod guided through an opening of the yoke of the gear arm arrangement.

20. The two-component dispenser in accordance with claim 18 , wherein the gear arm arrangement comprises a yoke with the first push rod guided through an opening of the yoke of the gear arm arrangement, and an open end of the yoke of the trigger lever is connected to an open end of the yoke of the gear arm arrangement.
