Ramming tip according to claim 1, characterized in that the ramming tip (1) has a substantially rotationally symmetrical outer shape, wherein the axis of rotation (R) runs substantially in the driving direction (E). 3. Ramming point according to one of claims 1 or 2, characterized in that the circular arc (12) of the circular segment or circular ring segment extends over 70° to 90°. 4. Ramming tip according to one of claims 1 to 3, characterized in that a plurality of concrete discharge channels (10), preferably three concrete discharge channels (10), are provided. 5. Ramming tip according to claim 4, characterized in that two concrete exit channels (10) of the plurality of concrete exit channels (10) are arranged in cross-section to the driving direction (E) along the inner wall (5) of the ramming tip (1) at substantially equal distances from each other. 6. Ramming point according to one of claims 1 to 5, characterized in that at least one radially inwardly projecting support device (13) for centering and / or positionally stable fixing of the driven pile (2) is provided on the inner wall (5). 7. Ramming point according to claim 6, characterized in that the at least one radially inwardly projecting support device (13) is designed as a plurality of support ribs. 8. Pile driver according to one of claims 1 to 7, characterized in that at least one second support web (6') with a second support surface (7') for an end face (8') of a pile end (4') is arranged on the inner wall (5) of the pile driver (1), wherein in the driving direction (E) the distance (T') of the second support surface (7') from the edge (11) of the pile driver (1) is greater than the distance (T) of the first support surface (7) from the edge (11) of the pile driver (1). 9. Ramming tip according to one of claims 1 to 8, characterized in that an outer diameter (D) of the ramming tip (1) decreases substantially continuously in the driving direction (E). 10. Ramming point according to one of claims 1 to 9, characterized in that the ramming point (1) is made in one piece. 11. Ramming point according to one of claims 1 to 10, characterized in that the ramming point (1) is made at least partially, preferably completely, of cast iron.

[0003] II. In all other respects, the counterclaim for nullity is dismissed.
