First claim
Opening claim text (preview).
The invention claimed is: 1. An end cap for a for a piston-cylinder unit comprising: a fastening portion; a base having a through-opening and an inner side opposite an outer cover surface; a seal carried by the base of the end cap; at least one discharge channel extending radially proceeding from the seal, the at least one discharge channel constructed at the end cap on the inner side with respect to the outer cover surface and with respect to the fastening portion. 2. The end cap according to claim 1 , wherein the seal comprises a socket and the at least one discharge channel comprises a channel base constructed so as to be lower in a discharge direction than the socket of the seal. 3. The end cap according to claim 2 , additionally comprising a fastening ring separate from the seal and wherein the seal is held at the end cap by the fastening ring. 4. The end cap according to claim 1 , wherein the at least one discharge channel is constructed as an open groove at the inner side of the end cap. 5. The end cap according to claim 4 , additionally comprising an axial groove in the fastening portion of the end cap, and wherein the open groove adjoins the axial groove. 6. The end cap according to claim 5 , additionally comprising a fastening ring separate from the seal and wherein the seal is held at the end cap by the fastening ring. 7. The end cap according to claim 4 , additionally comprising a fastening ring separate from the seal and wherein the seal is held at the end cap by the fastening ring. 8. The end cap according to claim 1 , wherein the base comprises a wall and wherein the at least one discharge channel is constructed as a tube inside the wall. 9. The end cap according to claim 8 , additionally comprising a fastening ring separate from the seal and wherein the seal is held at the end cap by the fastening ring. 10. The end cap according to claim 1 , additionally comprising a fastening ring separate from the seal and wherein the seal is held at the end cap by the fastening ring.
