  • the partition wall 3 has a groove 12 at its upper end. In this groove 12 engages the Middle web 13 of the insert 10 a. This center bar 13 can reach the upper end of the Insert 10 run.
  • the passage openings have a shape which causes the two components of the chambers 4 and 5 already on entering the Mixing chamber 14 of the mixing cannula 9 are mixed together.
  • two lateral passage openings 15 extend coaxially through the insert 10 to the upper end of the insert 10.
  • From the Outlet opening 8 of the chamber 4 extend two further passage openings 16 coaxially to the upper end of the insert 10.
  • the lower Entrance of the passage opening 17 communicates with the outlet opening 7 of the chamber 5, during the entrance of the passage opening 18 with the outlet opening 8 of the chamber. 4 communicated.
  • the passage openings 17, 18 each have an obliquely extending lip 19, 20, whose slopes are opposite to each other.
  • the Partition 3A in turn has a groove 12A into which the lower end of the central web 13A intervenes. This central web 13A extends axially through the insert 10A.
  • the Outlet opening 7 A communicates the passage opening 17 A, while with the Outlet opening 8A, the passage opening 18A communicates.
  • the lower part of the Mixing cannula 9A overlaps the insert 10A.
  • the passage opening 17A has a first Output 21 on.
  • the passage opening 18A also has a first outlet 22.
  • the Passage opening 17A comprises a circumferential direction of the insert 10A Channel 23, which opens into a second outlet 21A.
  • the passage opening 18A has also a running in the circumferential direction of the insert 10 A channel 24, the in a second output 22A opens.
  • the channels 23, 24 are by radially extending Wall parts 26 separated from each other. Their ends are located on the inner wall of the lower Part of the mixing cannula 9A, wherein this lower part engages over the insert 10A.
  • the channels 23, 24 are bounded on the outside by the inner wall 25 of the lower part of the mixing cannula 9A.
  • the channel 23 opens in the output 21A, while the channel 24 opens at the output 22A.
  • Output 21A has its output 22A displaced radially outwards, while the output 21A is offset radially outwards
  • Output 21A is offset radially outward to the output 22.
  • the outputs 21, 21A communicate with the passage opening 17A, while the outputs 22, 22A with the Passage opening 18 A communicate.
  • These outputs 21, 21A and 22, 22A are respectively circular segment-shaped, wherein the respective radially outer output 21A, 22A occupies a larger angular range than the adjacent output 21, 22.
  • the channels 23, 24 and the associated outputs 21A and 22A are respectively from the inner wall 25th limited.
