5. The apparatus according to claim 4 , wherein the liquid outlet is connected to the first section by means of a liquid trap.
6. The apparatus according to claim 5 , wherein the liquid trap comprises a duct from the liquid outlet to an inlet opening in the first section, wherein the liquid outlet is arranged higher than a lower end of the inlet opening and lower than an upper end of the inlet opening.
7. The apparatus according to claim 4 , wherein the pipe comprises a fifth section connecting the fourth section to the vent.
8. The apparatus according to claim 7 , wherein the fifth section is at least partly inclined upwardly.
9. The apparatus according to claim 7 , wherein the cooling means act on the fourth section and the fifth section.
10. The apparatus according to claim 7 , wherein a filler is arranged in the fifth section.
11. The apparatus according to claim 7 , wherein the fourth section comprises a first cooling jacket and the fifth section comprises a second cooling jacket, wherein the first cooling jacket comprises an inlet at one end and a connection to the second jacket at another end.
12. The apparatus according to claim 1 , wherein the pipe has an inner diameter of 25 mm or less.
13. The apparatus according to claim 3 , wherein the pipe comprises a fourth section which is inclined downwardly and connects the second section and a liquid outlet.
14. The apparatus according to claim 5 , wherein the pipe comprises a fifth section connecting the fourth section to the vent.
15. The apparatus according to claim 6 , wherein the pipe comprises a fifth section connecting the fourth section to the vent.
16. The apparatus according to claim 8 , wherein the cooling jacket act on the fourth section and the fifth section.
17. The apparatus according to claim 8 , wherein a filler is arranged in the fifth section.
18. The apparatus according to claim 9 , wherein a filler is arranged in the fifth section.
19. The apparatus according to claim 8 , wherein the fourth section comprises a first cooling jacket and the fifth section comprises a second cooling jacket, wherein the first cooling jacket comprises an inlet at one end and a connection to the second jacket at another end.
20. The apparatus according to claim 9 , wherein the fourth section comprises a first cooling jacket and the fifth section comprises a second cooling jacket, wherein the first cooling jacket comprises an inlet at one end and a connection to the second jacket at another end.
