Definitions

  • the invention relates to a pressure vessel according to the features of the preamble of claim 1.
  • the pressure vessel comprises a vessel body with a vessel bottom arranged at a lower end and formed in one piece with the vessel body, an end piece arranged at an upper end of the vessel body and formed in one piece with the vessel body and having an opening, an end piece arranged on the outside of a wall surrounding the opening of the end piece Connection geometry, wherein the wall forms a connection with the connection geometry, which is set up to be or be coupled to a corresponding further connection in a media-tight manner, a fastening structure for a valve formed on the inside of the wall surrounding the opening of the end piece, and a fastening structure in an overpressure opening of the End piece or an overpressure opening of the container body arranged overpressure protection.
  • a CO2 capsule and a device for automatically filling the capsule are described.
  • a one-way valve to be mounted on a 12 g CO2 capsule a 12 g CO2 capsule with a one-way valve created by installing a one-way valve and a filling device for filling the 12 g CO2 capsule with liquid carbon dioxide gas.
  • a device for use in paintballing includes a modified pressure bottle having a valve assembly "integrally" mounted in its neck and independent of the connection structure for connecting the bottle to a paintball marker.
  • the invention is based on the object of specifying a new type of pressure vessel.
  • a pressure vessel has a vessel body. At an upper end of the container body, an end portion is formed integrally with the container body. This end area, which is designed in one piece with the container body, can also be referred to as an end piece. The end area has an opening.
  • the pressure vessel also has a fastening structure for a valve, which is formed on the inside of a wall surrounding the opening of the end region.
  • two outflow openings are formed in the wall surrounding the opening of the end region, in particular opposite one another.
  • the pressure vessel for example a pressurized gas vessel, allows the valve or a valve function to be integrated into the end region and in particular enables the pressure vessel to be coupled directly, media-tight, to a further connection, for example a connection of an application.
  • this enables a medium located in the container body, for example gas, for example carbon dioxide, to flow out laterally.
  • the medium flows through the valve and then out through the two outflow openings in the wall and into the application.
  • the solution according to the invention is therefore particularly suitable for applications in which such a lateral outflow is required.
  • the solution according to the invention achieves a smaller overall height since the valve can be or is almost completely arranged in the container body. For example, only a collar-shaped upper section of a valve body of the valve protrudes from the container body, which is in sealing contact with an end face of the wall of the end region.
  • the pressure vessel also has the valve, which is arranged in the end region, in particular is screwed into it.
  • the valve is designed, for example, as a check valve.
  • a valve body of the valve has, in particular, exactly one passage opening, which is formed radially from an inside toward an outside of the valve body. This enables the valve body to be manufactured easily.
  • the valve body is particularly stable, since it has only a single passage opening and thus additional weakening caused by several passage openings is avoided.
  • the valve body can therefore be formed, for example, with less material expenditure and/or from another, in particular less expensive, material, for example from aluminum or brass.
  • the valve can have a plurality of such passage openings, which are each formed radially from the inside toward the outside of the valve body.
  • the passage opening or the respective passage opening in the valve body is positioned in particular at the level of the outflow openings in the end area. This ensures short flow paths between the passage opening in the valve and the two outflow openings.
  • the through-opening or the respective through-opening can also be offset in height relative to the height of the outflow openings in the end region.
  • the passage opening opens into a distributor groove formed circumferentially on the outside of the valve body and/or an inner opening edge of the respective outflow opening is arranged on a groove bottom of a distributor groove formed circumferentially on the inside of the wall of the end region.
  • the distributor groove is designed to be correspondingly wide or there is a connecting channel between the through-opening or the respective through-opening and the distributor groove or there is another fluidic connection between the through-opening or the respective through-opening and the distributor groove are provided.
  • the fastening structure has an internal thread arranged on the inside of the wall.
  • the valve body has an external thread that corresponds to the internal thread of the fastening structure.
  • the valve body When screwed into the internal thread, in particular completely, d. H. up to a predetermined end position, screwed-in state, the valve body is arranged in the area of the opening of the end area, protrudes from the opening into the end area, lies against the end area in a media-tight manner and has a receiving opening.
  • a sealing tappet is arranged in the receiving opening, which in a closed position closes the passage opening in a media-tight manner, i. H. either directly or indirectly closed media-tight, and releases the passage opening in an open position.
  • the valve has in particular a support element which is connected to the valve body or formed on the valve body and a spring element which is arranged inside the valve body and which is supported at a first end on the support element and at an opposite second end on the sealing tappet, the spring element being displaced during a movement of the sealing tappet is stretched from the closed position into the open position, in particular is compressed.
  • valve body With the valve body and the other valve components, which are held inside or on the valve body, allows a particularly simple assembly of the valve as a whole in the end area. Since, in contrast to solutions with a separate valve known from the prior art, the valve does not have a holding function, the valve body can be dimensioned significantly weaker in terms of its material thickness and quantity of material.
  • At least one seal is arranged between the valve body and the end area.
  • a seal is arranged between the valve body and the end area above and below the passage opening.
  • the seal above the passage opening is a Prevents the medium from flowing out of the opening in the end area upwards out of the container body.
  • the seal below the passage opening prevents the medium from flowing between the wall of the end region and the valve body and thus past the valve in the direction of the outflow openings in the wall of the end region.
  • two seals for example in the form of an O-ring or a shaft seal, are also arranged between the valve body and the sealing tappet.
  • a seal is arranged above the passage opening in order to prevent the medium from flowing out of the receiving opening upwards, so that it is ensured that the medium flows out laterally exclusively via the two lateral outflow openings.
  • the other seal is arranged below the passage opening.
  • the passage opening is fluidically connected to the receiving opening and the sealing plunger in the closed position closes the receiving opening and thus also the passage opening in a media-tight manner and in the open position releases the receiving opening at least in sections and thereby also releases the passage opening.
  • the through-opening is thus closed media-tight in particular indirectly by means of the sealing plunger in the closed position, in that the receiving opening and thereby the through-opening fluidically connected thereto are closed in a media-tight manner.
  • the support element and/or the valve body has an inflow opening.
  • the inflow of a medium located inside the container body at least when the sealing plunger is in the open position, into the receiving opening in the valve body and thus at least when the valve tappet is in the open position, allows the medium to flow in the direction of the passage opening.
  • the valve body has a pressure equalization opening. This enables the valve tappet to be moved into the open position and back into the open position, particularly when the support element is closed, with pressure equalization taking place between an area of the receiving opening below the sealing tappet and the interior of the container body.
  • the container body has a container bottom which is arranged at a lower end and is formed in one piece with the container body.
  • a particularly high level of pressure stability is achieved with little effort, in particular with little material expenditure, since connections, for example weld seams, which represent weak points, are avoided.
  • the container body has, in particular, a connection geometry arranged on the outside of a wall surrounding the opening of the end region, for example an external thread, a latching arrangement or a quick-release fastener, the wall forming a connection with the connection geometry, which is set up to be coupled with a corresponding further connection in a media-tight manner to become or to be.
  • a connection geometry for example a so-called ACME thread, at the end area, the valve can be omitted as a separate component.
  • connection geometry at the end area and thus at the pressure vessel due to the design of the connection geometry at the end area and thus at the pressure vessel, a reliable and improved media tightness can be achieved, which results in particular from a reduction in the number of joints and their sealing compared to the solutions known from the prior art with a separate valve. Furthermore, assembly costs are reduced.
  • a seal provided in the prior art for sealing the valve from the pressure vessel in particular a so-called O-ring, can also be omitted, which also results in a reduction in the number of individual parts and a reduction in costs.
  • the valve Due to the integration of the valve in the pressure vessel and the formation of the external thread in the end area, the valve no longer has to be made of brass.
  • both the pressure vessel, i. H. the container body with container base and the end area, as well as the components of the valve are made of aluminum.
  • the valve is made of brass or another material, for example.
  • the vessel body and the end area are produced together from a material blank in a roll-forming process.
  • the Fastening structure for the valve and in particular also the connection geometry by means of machining and/or forming, in particular during the roll forming process, and/or applying material and/or other suitable processes in the area of the end region.
  • the two outflow openings are formed in the wall of the end area.
  • the valve is then attached to the end area in the area of the opening.
  • the pressure vessel can be produced particularly easily and with high quality using the roll forming process.
  • the production of the fastening structure and the fastening of the valve can also be implemented particularly easily, reliably and at low cost.
  • the pressure vessel can, for example, additionally have an overpressure safety device.
  • this overpressure protection is arranged in the valve.
  • this overpressure protection is arranged, for example, in an overpressure opening formed in the bottom of the container.
  • a corresponding design of the container base for example with a corresponding depression, this enables an integrated arrangement of the overpressure safety device without it protruding beyond an outer edge of the pressure container. This increases protection against mechanical damage to the overpressure protection.
  • a required installation space for accommodating the pressure vessel in an application can be reduced and assembly of the pressure vessel in the installation space is simplified.
  • the overpressure protection includes, for example, a bursting disk, which is secured, for example, with a screw including a vent bolt.
  • a design of the overpressure protection is particularly simple, inexpensive and reliable.
  • the overpressure protection is designed for a triggering pressure of 250 bar.
  • any other triggering pressure values are also possible.
  • the bursting disk is fluidically coupled to an interior of the pressure vessel and is, for example, at the edge of the screw held, within which a vent bolt is formed or arranged. If the triggering pressure is exceeded, the bursting disk is mechanically destroyed and releases a fluidic connection between the vent bolt and the interior of the pressure vessel, so that fluid, for example gas, located within the pressure vessel can escape.
  • the overpressure opening includes an internal thread that corresponds to an external thread of the screw and into which the screw is screwed.
  • the internal thread is produced by machining.
  • the internal thread can also be produced in a forming process, for example a roll forming process, during the shaping of the container bottom.
  • other methods for producing the internal thread are also possible.
  • the overpressure opening in the vessel bottom is produced by means of machining and/or forming, in particular during the roll forming process, and/or the application of material and/or other suitable methods, and the overpressure safety device is then attached to the overpressure opening.
