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 compressed gas are filled, for example, for gas filling of creamers, for inflating bicycle tires or for making carbonated drinks be used.
- Drusolcheckgaskapsetn Such Drusolcheckgaskapsetn are known. So shows, for example CH-A 511 396, which as the next State of the art eye becomes, a compressed gas capsule consisting of a hollow body and a used therein check valve.
- the check valve has a Valve body, which is provided with a longitudinal bore, in which a Valve pin is guided displaceably.
- the valve pin In filled with compressed gas state of Pressurized 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 pushed inwards, with tongues on the outside at the edge of the valve pin are provided, which are bent outwards, thereby avoiding is that the valve pin can be pressed too far inward.
- pressure gas capsules which after the Filling be closed by a membrane, which when opening must be punctured. These compressed gas capsules can only once be used and then thrown away and also disposed of become.
- the object of the present invention is now a To create compressed gas capsule, which several times after emptying in easier Can be refilled without having to replace parts, and in which the functionality is full even after multiple use is guaranteed.
- the stops are in the form of projections formed, which integrally formed on the existing of a plastic valve body are.
- the valve body can be produced in one operation be, the valve pin is pressed into the valve body, wherein the projections elastically recede and after inserting the valve pin go back to its original shape.
- the hollow body consists of a metallic Material, wherein at least its surface is corrosion resistant is. This ensures in particular in the multiple reusability, that the condition of the compressed gas capsule also in aesthetic terms remains optimal.
- a further advantageous embodiment of the compressed gas capsule is in that the connection between the hollow body and the valve body takes place in such a way that that provided between valve body and valve pin sealing point within of the hollow body is arranged so that damage to the valve body outside the hollow body no effect on the tightness of Have compressed gas capsule.
- the compressed gas capsule 1 is shown, which consists of a with a Opening 2 provided hollow body 3 consists.
- This hollow body 3 is made made of a metallic material, wherein at least the surface corrosion resistant is. Inserted into the opening 2 is the check valve. 4
- This check valve 4 consists of a valve body 5, with a continuous longitudinal bore 6 is provided, in which a constriction 7 is provided.
- the constriction 7 is at its end, which is against the Hollow body is directed towards, designed as a truncated cone 8, which is against the Hollow body 3 expands out.
- valve pin 9 In the longitudinal bore 6 of the valve body 5, a valve pin 9 is inserted.
- This valve pin 9 has a thickening 10, as against the inside of the hollow body 3 is 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 on each other. This is done automatically by the overpressure of the in the Compressed gas capsule 1 filled CO2 gas. In this state, as shown in Fig. 1 is shown, the valve pin 9 is in its first end position.
- the protruding into the hollow body 3 end portion of the valve body 5 has three projections projecting radially inwards into the longitudinal bore 6 12, wherein in the illustration according to FIG. 1, only one is visible.
- the valve body 5 is made of a plastic, the projections 12 are formed directly on the valve body 5. Prevent these projections 12 that the valve pin 9 against the inside of the hollow body 3 out of the Can move out valve body 5. Through these projections 12, as a stop act, the second inner end position of the valve pin 9 in the longitudinal bore 6 of the valve body 5 fixed.
- valve pin 9 When inserting the valve pin 9 in the valve body 5 is the Valve pin 9 pressed over the projections 12, and since the valve body 5 made made of a plastic which has a certain elasticity, soft 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. Thereafter, this area of the valve body 5 takes the original Form, the valve pin 9 is trapped.
- the check valve 4 is inserted into the opening 2 of the hollow body 3.
- a groove 13 is pressed over the entire circumference, whereby the desired connection is achieved.
- This groove 13 comes in one Area of the valve body 5 to lie, from the inside of the hollow body 3 seen from outside the constriction 7 is located. This is especially the sealing area of the check valve 4 optimally protected, a Damage of the over the hollow body 3 projecting portion of the valve body 5, for example by dropping, has no influence on the sealing point, the compressed gas can not escape.
- the valve pin 9 has on to the widening truncated cone 11th adjoining end region on a flange-shaped thickening 14. These flange-shaped thickening 14 comes on three flats 15 to the plant, the along the displacement of the valve pin 9 distributed over the circumference and running parallel in the longitudinal bore 6 are mounted. In the sectional view 1, only one of these flats 15 is visible.
- Valve pin 9 can extend inwards.
- FIG. 4 shows a detail of a device 17 in which the receiving part 18 is arranged for the compressed gas capsule.
- This device 17 for example, a cream blower, a pumping 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 inserted, which has a sealing jacket 21 on the inside. To the projecting into the opening 19 portion of the hollow pin 20th a sealing ring 22 is placed.
- the receiving part 18 can now be the compressed gas capsule 1 with the Fit non-return valve 4.
- the valve pin 9 is in its first End position, that is, the hollow body 3 is tightly closed, the interior the hollow body 3 is filled with the pressurized gas.
- the plant for refilling the inventive pressure gas capsules 1 could comprise a receiving part which corresponds to the receiving part 18 Fig. 4 and 5 corresponds, wherein only instead of a sealing jacket 21 another embodiment of the hollow bolt 20 would have to be done.
- the Gas cylinder 1 could thus in the same way in the receiving part of a Refilling system are used, as shown in FIG. 5 is shown, the hollow pin would also push back the valve pin, 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 Pressurized gas capsule would immediately pressed into the sealing position.
- the receiving part 18 according to 4 and 5 to change such that the sealing ring 22 is not around the Hollow pin 21 is placed, but in a corresponding groove in the opening 19 could be inserted, whereby the seal between receiving part 18th and valve body would take place on the outside thereof.
