  • the piston 14 and the jacket 36 are in the direction 23 to the jacket 41 or 42 before. So the piston 14 stands over the rest of the body 6, namely the jacket 32 before.
  • the clamping surface 47 has different ones Gradients. In the area where they are in the safety position bears on the counter surface 48, it has the slightest slope.
  • the surface 48 is shaped like a spherical cap Deepening or through the free end face of the Piston 14 formed. On them is the spherical cap-shaped projection 47 adjusted.
  • the two surfaces 47, 48 thus form one spring detachable snap connection of the locking means 50. Das Locking member 49 is therefore unnecessary. From the intervention in the Surface 48, surface 47 falls in both directions 24, 25 as well as transversely to the legs 46 from flat.
  • a blind hole in the channel 13 extends from the surface 48 only over a minor portion of the length of the shaft 15 in the coat 36 into it.
  • the blind hole connects to the floor transverse channels 68 to the inner circumference of the Sheath 36 are directed. From this inner circumference and that Axial channels 69 are delimited on the outer circumference of the shaft 15, the laterally opposite the axis 10 and the channel 13 are offset. At the upstream ends of channels 69 each connects a transverse channel 68. The downstream Ends extend to the associated end of the shaft 15. Die Channels 69 can be formed by longitudinal grooves in the shaft 15 and open into the vortex or swirl device 70. Their Channel depressions are only in the inside of the end wall 71 of the connector 34 provided. The cross section of the channels 69 is much smaller than that of the channels 13, 68.
  • the opening 72 of the channel 13, which passes through the surface 48, is closed pressure-tight by the surface 47. So a manually operated valve is formed and contamination the outlet channel 13, 68, 69, 70 during the Storage is prevented.
  • the cam 49 stands over one of the plate surfaces, namely the wedge surface 47, partially before; 5, the cam 49 protrudes laterally the outsides of the central portion of part 21; 7, the cam 49 is only over the deepest part the area 47 in front, but not over the highest part. 4 can due to the self-locking on a snap lock to be dispensed with.
  • the snap lock is here directly opposite the memory 8 possible.
  • the closing surface 19 is from the outlet 12 to the outer circumference of the memory 8 continuously flat.
  • Part 21 has one Deepening, which is limited throughout its scope is and receives the seal 30. So are the two sides Level 26 the narrow legs 46 and on both sides of it rectangular projections 55, 58 are formed, which adjoin this deepening.
  • the handle 55 stands around the wall 33 and the jacket 41 as a plate or button a measure that is at most as large as half the parallel, narrower extension of the wall 33. So the handle 55 lies at a distance from the outer circumference of the body 5 to 7.
  • Parts 8, 30 could also be made of the same material exist or be formed in one piece with each other.
  • the guide 40 or its openings 51, 52 are exclusive provided in the jacket 42.
  • the memory 8 first in direction 23 in the body 5 and then with this in same direction in the body 7 are used. After that part 21 is used in direction 25. The so educated The assembly can then be attached to the body 6 in the direction 22 become. Only then do the surfaces 47, 48 come into mutual contact Engagement until the axial locking pressure is established. It could also be just bodies 5, 7, 8 as pre-assembled Group are added to the body 6, after which the part 21st is used.
  • the opening movement of part 21 can also be a rotary motion, e.g. around axis 10 or around one Axis 10 laterally offset parallel axis. Also a move across to level 26 is conceivable.
  • the seal only or additionally with radial pressure on the inner circumference of the Apply outlet 12. This allows the seal to snap fit form, which secures the part 21.
  • the seal 30 or the surface 31 can contain germicidal substances, which e.g. are mixed with their material.
