Definitions

  • the invention relates to a valve device for compressed gas packaging according to the preamble of claim 1.
  • valve device is known from DE-OS 43 08 068.
  • a small amount of propellant gas from the Head space of the compressed gas pack is blown by stem and spray head. It becomes the content of the stem and spray head with high pressure emptied and thus stem and spray head after each product removal cleaned. This prevents sticking.
  • the known valve device has the disadvantage that it improper use or if the stem is stuck in one Position that is just below its upper position, an undesired Gas escapes from the compressed gas pack to a complete one Emptying the compressed gas pack can cause blow out of gas when the stem passes this position.
  • the known valve device has the disadvantage that in addition A cleaning process is carried out at the start of a product withdrawal. This cleaning process is not necessary because before, when you have finished Product removal, a cleaning process has already been carried out. Of the second cleaning process leads to excessive gas loss.
  • the invention is based on the object of a valve device for To design compressed gas packaging of the type mentioned at the beginning, that unwanted gas leakage cannot occur, and that only a limited cleaning process after a product removal process occurs.
  • a valve housing of a valve device by means of a spring with respect to a housing surrounding the valve housing upwards deferred, is provided in this upper position in the housing first gas channel closed by a seal of the valve housing, and is a second gas channel between the valve housing and the housing recessed, the first with the valve housing set down Gas channel and through a passage between the valve housing and the Seal of the valve plate is connected to the room.
  • the valve device according to the invention has the advantage that an undesired Gas leakage can not take place, and that only limited Cleaning process occurs after a product removal process.
  • a lockable room for recording and delivering a certain amount of gas is a limited consumption of gas for cleaning the stem and spray head. Only a volume serves a cleaning process.
  • gas is released from the headspace of the Compressed gas packaging passed into the room via the two gas channels, see above that it is filled with gas of high pressure.
  • the gas After your product removal process is the gas through a side opening of the stem and through released the stem to the environment. Doing the stem and one on your stem located spray head cleaned by the gas stream. It takes place only one cleaning process directly after a product removal process. If the stem is not completely raised, there is either no stem Product delivery or just a gas delivery corresponding to the volume of the room.
  • the second gas channel runs parallel to the central axis of the star, it runs the first gas channel in the radial direction away from the central axis of the stone, and limits the seal of the inner housing in its upper position second gas channel down and closes the first gas channel (Claim 2), is a safe interruption of the gas flow in a simple manner possible from the headspace to the stem.
  • the interrupt is particularly safe insofar as it is interrupted twice. To the one between the channels and the other at the passage.
  • a valve device 2 with a Valve body 3 is provided, which consists of a hollow stem 4 and a with the stem 4 connected stem body 5.
  • the Stem 4 protrudes a valve housing 6 out.
  • the valve housing 6 opens into the Compressed gas packaging 1.
  • a valve plate 8 closes the Compressed gas packaging 1 and has an opening 9. Through the opening 9 extends the hollow stem 4.
  • the valve housing 6 is through a Stone 4 surrounding seal 10 sealed against the valve plate 8. Of the Stem 4 has a side opening 11.
  • the opening 11 is almost relaxed spring 7 (right in Figure 1), so if the stem 4 in its upper rest position is connected to a room 12. At a distance a further seal 13 is provided from the upper seal 10.
  • This Seal 13 closes with the valve housing 6.
  • the room 12 is located between the seals 10 and 13.
  • the space 12 is pressed Stem 4 (on the left in FIG. 1) via a passage 14 on the valve housing 6 the head space 16 of the compressed gas pack 1 containing the propellant 15 connected.
  • the valve housing 6 is opposed by means of a spring 17 a housing 18 surrounding the valve housing 6 reset upwards.
  • In this upper position there is a first one provided in the housing 18 Gas channel 19 closed by the seal 13 of the valve housing 6.
  • This gas channel 20 is in the down position Valve housing 6 with the first gas channel 19 and via the passage 14 between the valve housing 6 and the seal 10 of the valve plate 8 with your room 12 connected.
  • the second gas channel 20 runs parallel to Central axis 21 of the stem 4.
  • the first gas channel 19 runs in a radial direction Direction away from the central axis 21 of the stem 4.
  • the seal 22 of the Valve housing 6 delimits second gas channel 20 in its upper position downward and thereby closes the first gas channel 19.
  • the Stem 4 is in its held lower position, its stop 23 against a floor 24th of the valve housing 6 is pressed. At this position, gas 25 is turned off the head space 16 of the compressed gas packaging 1 via the two gas channels 19 and 20 passed into the room 12, so that this with gas 25 high pressure is filled. After the product removal process, the gas 25 becomes after Stem 4 above through the lateral opening 9 of the stem 4 and released by the stem 4 to the environment. A stop 26 limits the return of the stem 4 upwards and seals there analogously to the Seal 13 from a product space 27 opposite the space 12. The gas 25 from room 12 cleans the stem 4. There is only one cleaning process directly after a product removal process.
