Definitions

  • the present invention relates to a compressed gas capsule according to the preamble of claim 1.
  • Such compressed gas capsules for example with CO2 as a compressed gas filled, for example for gas filling of cream blowers, for inflating bicycle tires or for making carbonated beverages be used.
  • Compressed gas capsules of this type are known.
  • CH-A 511 396 a compressed gas capsule, which consists of a hollow body and a there is a check valve used.
  • the check valve has one Valve body, which is provided with a longitudinal bore in which a Valve pin is slidably guided.
  • the valve pin In the state filled with compressed gas Compressed gas capsule, the valve pin is pressed into a front end position, in which it is pressed against a sealing lip, the compressed gas capsule is sealed.
  • the valve pin is used to fill or empty the compressed gas capsule pushed inwards, with tongues on the outside on the edge of the valve pin are provided, which are bent outwards, thereby avoided the valve pin can be pushed in too far.
  • compressed gas capsules which after Filling can be closed with a membrane, which when opening must be pierced. These compressed gas capsules can only be used once must be used and then thrown away and also disposed of will.
  • the object of the present invention is now a Pressurized gas capsule to create the multiple after emptying in easier Can be refilled without parts having to be replaced, and in which the functionality is full even after repeated use is guaranteed.
  • the stops are advantageously in the form of projections formed, which is molded onto the valve body made of a plastic are. This allows the valve body to be manufactured in one operation be, the valve pin is pressed into the valve body, the projections shrink elastically and after inserting the valve pin go back to the original form.
  • the hollow body advantageously consists of a metallic one Material, at least the surface of which is corrosion-resistant is. This ensures, particularly in the case of multiple reusability, that the condition of the compressed gas capsule also in aesthetic terms remains optimal.
  • connection between the hollow body and the valve body takes place in such a way that the sealing point provided between the valve body and valve pin within of the hollow body is arranged so that damage to the valve body outside of the hollow body no impact on the tightness of the Have compressed gas capsule.
  • the compressed gas capsule 1 is shown, which consists of a Opening 2 provided hollow body 3 exists.
  • This hollow body 3 is made made of a metallic material, at least the surface being corrosion-resistant is.
  • the check valve 4 is inserted into the opening 2.
  • This check valve 4 consists of a valve body 5, which with a continuous longitudinal bore 6 is provided, in which a constriction 7 is provided.
  • the narrowing 7 is at its end region, which against the Hollow body is directed as a truncated cone 8, which is against the Hollow body 3 expanded.
  • a valve pin 9 is inserted into the longitudinal bore 6 of the valve body 5.
  • This valve pin 9 has a thickening 10, which as against the inside of the hollow body 3 widening truncated cone 11 is formed.
  • the truncated cone 11 of the valve pin 9 and the truncated cone 8 of the valve body 5 are sealed in the closed state of the check valve 4 pressed together. This is done automatically by the overpressure in the Compressed gas capsule 1 filled with CO2 gas. In this state, as shown in FIG. 1 is shown, the valve pin 9 is in its first end position.
  • the end region of the valve body protruding into the hollow body 3 5 has three projections projecting radially inwards into the longitudinal bore 6 12, only one being visible in the illustration according to FIG. 1.
  • the valve body 5 is made of a plastic, the projections 12 are formed directly on the valve body 5. These projections 12 prevent that the valve pin 9 against the inside of the hollow body 3 from the Can extend valve body 5. Through these projections 12, which act as a stop act, the second inner end position of the valve pin 9 in the longitudinal bore 6 of the valve body 5 set.
  • valve pin 9 When inserting the valve pin 9 in the valve body 5, the Valve pin 9 pressed over the projections 12, and since the valve body 5 from is made of a plastic that has a certain elasticity the projections 12 together with the lower edge of the valve body 5 elastic back until the thickening 10 of the valve pin 9 these projections 12th has run over. Then this area of the valve body 5 takes the original one Form, the valve pin 9 is caught.
  • a groove 13 is pressed over the entire circumference, whereby the desired connection is reached.
  • This groove 13 comes in one Area of the valve body 5 to lie, which is from the inside of the hollow body 3 seen from outside the constriction 7. This is especially the sealing area of the check valve 4 optimally protected, a Damage to the area of the valve body projecting beyond the hollow body 3 5, for example by dropping it, has no influence on the sealing point, the compressed gas cannot escape.
  • valve pin 9 points to the expanding truncated cone 11 subsequent end region on a flange-shaped thickening 14.
  • This flange-shaped thickening 14 comes on three flats 15 to the plant along the displacement of the valve pin 9 distributed over the circumference and are mounted in parallel in the longitudinal bore 6. In the sectional view 1, only one of these flats 15 is visible.
  • valve pin 9 is held in the central axis of the longitudinal bore 6, the one or escaping gas finds the passage in the between the flats 15 remaining gap-shaped openings 16, creating an optimal Function of this check valve is achieved.
  • FIG. 4 shows a section of a device 17, in which the receiving part 18 is arranged for the compressed gas capsule.
  • This facility 17 can, for example, a cream blower, a pump device for a bicycle tube or a device for carbonating liquids.
  • the Receiving part 18 has an opening 19, in which in a known manner Hollow pin 20 is used, which has a sealing jacket 21 on the inside. Around the area of the hollow bolt 20 protruding into the opening 19 a sealing ring 22 is placed.
  • the receiving part 18 can now be the compressed gas capsule 1 with the Put on check valve 4.
  • the valve pin 9 is in its first End position, that is, the hollow body 3 is sealed, the interior of the hollow body 3 is filled with the compressed gas.
  • the system for refilling the compressed gas capsules according to the invention 1 could comprise a receiving part which corresponds to the receiving part 18 4 and 5 corresponds, only instead of a sealing jacket 21 a different configuration of the hollow bolt 20 would have to take place.
  • the Pressurized gas container 1 could thus in the same way in the receiving part Refilling system can be used, as is essentially in Fig. 5th is shown, the hollow pin would also push the valve pin back, the gas could flow in the opposite direction and the compressed gas capsule fill up.
  • the valve pin 9 by the pressure of the gas in the Compressed gas capsule would be pressed immediately into the sealing position.
