Definitions
- Valve for a gas cartridge gas cartridge for a water soda maker and method for filling such a gas cartridge
- the present invention relates to a valve for selectively closing and selectively opening a gas cartridge for a soda maker, the valve being adapted to retain a gas in the gas cartridge when it is closed and to provide fluid connection to the gas cartridge when it is opened, wherein the valve comprises a valve housing having a cartridge connection opening aligned along a longitudinal axis of the valve so that gas can flow into and out of the cartridge in the direction of the longitudinal axis.
- valves are used on gas cartridges, in particular ( ⁇ -cartridges, for soda makers.
- Such water soda makers are also referred to as carbonizers and typically have a gas cartridge connection via which the gas cartridge, or the valve of the gas cartridge, can be connected to the water soda maker.
- the valve of the gas cartridge can then optionally be opened via an actuating device of the water soda maker in order to remove gas, in particular CO2, from the gas cartridge and supply it to a container with liquid to be carbonated, for example drinking water.
- Such a valve for a gas cartridge is known from DE 20 2020 005 533 U1.
- the known valve includes a cartridge connection opening through which gas can be filled into a receiving space of the gas cartridge and removed from it.
- This cartridge connection opening is arranged along a direction parallel to the longitudinal axis, so that gas can flow into and out of the receiving space of the gas cartridge in the direction of the longitudinal axis.
- at least one external connection opening is provided in this valve, which opens laterally to the longitudinal axis, so that the gas can flow out of the valve in a direction perpendicular to the longitudinal axis when it is removed from the water soda maker.
- the object of the present invention is to provide a valve or a gas cartridge in which lateral recoil forces are reduced.
- a valve for selectively closing and selectively opening a gas cartridge for a soda maker is proposed, the valve being designed to hold a gas in the gas cartridge when it is closed and to provide a fluid connection to the gas cartridge when it is open , wherein the valve comprises a valve housing having a cartridge connection opening aligned along a longitudinal axis of the valve such that gas can flow into and out of the gas cartridge in the direction of the longitudinal axis, and wherein the valve housing comprises at least one outlet opening, which externally and arranged along a direction parallel to the longitudinal axis in such a way that gas can flow out of the valve in the direction parallel to the longitudinal axis.
- the valve according to the invention is designed to be selectively closed and selectively opened, so that gas can be removed from the gas cartridge and the gas cartridge filled with gas optionally.
- the valve When the valve is closed, the gas can be held in the gas cartridge.
- a fluid connection to the gas cartridge, in particular a receiving space of the gas cartridge is provided so that removal or filling can take place.
- the gas can be removed from the gas cartridge via the outlet opening, the outlet opening being arranged on the outside and oriented in such a way that gas flows out of the valve in a direction parallel to the longitudinal axis of the valve housing, so that any recoil forces caused by the outflow are parallel to the Act longitudinally. In this way, recoil forces perpendicular to the longitudinal direction can be reduced or avoided.
- the Gas cartridge with the valve in a soda maker reduces lateral forces when removing gas.
- the outlet opening is arranged such that the gas can escape in a direction that points away from the cartridge connection opening.
- valve housing has exactly one outlet opening, which is arranged on the outside and along a direction parallel to the longitudinal axis in such a way that gas can flow out of the valve in the direction parallel to the longitudinal axis.
- outlet openings can be provided, for example two, three, four, five or six.
- the at least one outlet opening is arranged at a distance from the longitudinal axis.
- the outlet opening By arranging the outlet opening in this way, the gas can be released from the gas cartridge both in the direction parallel to the longitudinal axis and in a region of the valve spaced from the longitudinal axis, for example in a lateral edge region of the valve.
- the valve can have a cylindrical shape and the at least one outlet opening can be located in the radial direction from the cylinder axis.
- a ratio of the distance of the outlet opening from the longitudinal axis to a distance of the outlet opening from an outer contour of the valve housing arranged parallel to the longitudinal axis is in the range from 10 to 1000, preferably in the range 10 to 150, particularly preferably in Range 25 to 100.

- the ratio mentioned is particularly preferably in the range from 40 to 50, for example 45.
- the choice of such a ratio can contribute to that the gas flows out of the valve in an area laterally distant from the longitudinal axis, but the gas flows out of the valve parallel to the longitudinal axis.
- the at least one outlet opening is designed in the shape of a ring segment, in particular in the shape of a segment of a circular ring, or in the shape of a ring, in particular in the shape of a circular ring.
- the ring segment-shaped or annular outlet opening allows the gas to flow out of the valve concentrically to the longitudinal axis.

- the valve housing has a sealing element, in particular a sealing ring, for sealing the housing sleeve from the housing core, which is arranged on a side of the housing sleeve opposite the outlet opening.
- the sealing element can be used to seal the gap between the housing core and the housing sleeve on the side opposite the outlet opening, so that an undesirable outflow of gas is prevented by other means than through the outlet opening.
- the housing core has a feed channel which is arranged transversely, in particular perpendicularly, to the longitudinal direction and opens into a mouth in an intermediate space between the housing sleeve and the housing core.
- a fluid connection between an interior of the valve housing and the outlet opening or between the cartridge connection opening and the outlet opening can be provided via the supply channel.
- the space between the housing sleeve and the housing core preferably extends parallel to the longitudinal direction and has the at least one outlet opening.
- the housing core has a larger cross-sectional width, in particular a larger diameter, on a side of the mouth facing the cartridge connection opening than on a side of the mouth facing away from the cartridge connection opening. Due to the different cross-sectional widths on the sides of the mouth, the outflowing gas, which flows through the feed channel, can be redirected in the direction parallel to the longitudinal axis and flow out of the outlet opening in this direction.
- a step can be provided on the outer contour of the housing core, which is arranged at the level of the mouth of the feed channel. If the housing core is cylindrical in the area of the mouth, it has a larger diameter on a side of the mouth facing the cartridge connection opening than on a side of the mouth facing away from the cartridge connection opening.
- a groove is arranged in the outer contour of the housing core, which runs parallel to the longitudinal direction, in particular exactly one groove.

- the retaining element preferably protrudes from the valve housing in a direction oblique, in particular perpendicular, to the longitudinal axis of the valve housing. If the valve is inserted into the gas cartridge connection of the soda maker, for example by a movement in the direction of the longitudinal axis, the retaining element can be engaged behind by a holding element of the soda maker and thereby the valve or the gas cartridge can be fixed to the soda maker.
- a pressure relief valve in particular comprising a rupture disk, is arranged on the valve housing, which is configured to allow excess pressure existing in the area of the cartridge connection opening to escape.
- the rupture disk is preferably configured in such a way that it bursts at a predetermined excess pressure in the area. When the rupture disk ruptures, a connection can be established between the cartridge connection opening and the environment.
- the pressure relief valve preferably comprises an external pressure relief outlet opening which opens laterally to the longitudinal axis.
- the valve has a cartridge closure element which is biased into a closed position, in which the cartridge closure element closes a passage between the outlet opening and the cartridge connection opening, the cartridge closure element being activated by an actuating element of the Valve can be moved towards an open position in which the passage between the outlet opening and the cartridge connection opening is opened for discharging gas.
- the actuating element of the valve is preferably movable along the longitudinal axis.
- the actuating element can be actuated by an activation element of a soda maker that interacts with the actuating element, for example by an activation pin, when the valve or the gas cartridge is connected to a gas cartridge connection of the water soda maker.
- the cartridge closure element is preferably prestressed in the direction of the closed position by means of a first spring element.
- the first spring element can be designed as a helical spring, preferably as a helical compression spring.
- the aforementioned open position of the cartridge closure element can also be used to open a passage between the cartridge connection opening and any filling opening of the valve housing for introducing gas into the gas cartridge.
- the valve housing has a filling opening on a side opposite the cartridge connection opening, through which gas can flow into the valve in the direction of the longitudinal axis. The filling opening is thus aligned along a longitudinal axis of the valve.
- the filling opening offers the advantage that it is not necessary to fill the gas cartridge via the outlet opening.
- the valve housing has a filling opening on a side opposite the cartridge connection opening, through which gas can flow into the valve in the direction of the longitudinal axis, the actuating element having the filling opening.
- the actuating element has a dual function: on the one hand, it can be used to actuate the gas extraction, in particular pressed in, and it provides a filling opening for filling the gas cartridge. It is therefore possible to apply both a pressure force that activates the removal of gas in the direction of the longitudinal axis - in particular through an activating element of a water soda maker - and also to introduce gas into the valve in the direction of the longitudinal axis during filling.
- the valve housing has a filling opening on a side opposite the cartridge connection opening, through which gas can flow into the valve in the direction of the longitudinal axis, the filling opening being arranged between an outer contour of the actuating element and an inner contour of the valve housing , wherein the filling opening is designed in particular as a ring.
- This configuration offers the possibility that the actuating element can be used, in particular pressed in, to actuate the gas extraction.
- the actuating element can have one or more internal, in particular lateral, openings which open or open into an intermediate space between the outer contour of the actuating element and the inner contour of the valve housing. Via this internal opening or openings, gas which flows into the valve in the direction of the longitudinal axis can be guided into the actuating element, in particular along a direction transverse, preferably perpendicular, to the longitudinal direction.
- the outlet opening is at a smaller distance from the cartridge connection opening than the filling opening.
- the filling opening is arranged offset from the outlet opening with respect to the longitudinal axis.
- the filling opening can be aligned along the longitudinal axis of the valve, like this that gas can flow into the valve in the direction of the longitudinal axis while the outlet opening is arranged at a distance from the longitudinal axis and and is arranged along a direction parallel to the longitudinal axis such that gas can flow out of the valve in the direction parallel to the longitudinal axis.
- the valve has an inlet closure element which is biased into a closed position by a second spring element, in which the inlet closure element closes a passage between the filling opening and the cartridge connection opening or the filling opening, whereby the second spring element is designed such that the inlet closure element can be moved into an open position by applying a predetermined gas pressure to the filling opening, in which the passage between the filling opening and the cartridge connection opening or the filling opening is opened for introducing gas.
- the prestressed inlet closure element therefore provides a partial filling valve in the manner of a check valve, which holds gas in the valve and admits gas if there is a gas pressure at the filling opening that exceeds the predetermined gas pressure.
- the second spring element can be designed as a helical spring, preferably as a helical compression spring.
- the valve additionally has a cartridge closure element which is biased into a closed position in which the cartridge closure element closes a passage between the filling opening and the cartridge connection opening, the cartridge closure element passing through the inlet -Closing element of the valve can be moved in the direction of an open position, in which the passage between the filling opening and the cartridge connection opening is opened for introducing gas.
- the cartridge closure element can also be moved into its open position. In this way, a fluid connection can be established between the inlet opening and the cartridge connection opening, via which the gas cartridge can be filled.
- the cartridge closure element is preferably the same cartridge closure element, which in the closed position closes a passage between the outlet opening and the cartridge connection opening.
- the valve preferably comprises, in particular in the area of the cartridge connection opening, a thread for connecting the valve to an opening of a gas cartridge.
- the thread is preferably designed as an external thread so that it can be screwed to a corresponding internal thread of the gas cartridge.
- a gas cartridge is also proposed for connecting to a gas cartridge connection of a water soda maker with a valve described above.
- the gas cartridge can achieve the same advantages and effects that have already been explained in connection with the valve according to the invention.
- the gas cartridge preferably has a thread, particularly preferably an internal thread, in particular in the area of an opening, via which the valve is connected.
- the gas cartridge can, for example, be designed in accordance with the DIN EN ISO 7866:2021-05 standard.
- the invention further relates to a method for filling a gas cartridge described above, wherein the valve housing has a filling opening on a side opposite the cartridge connection opening, via which gas is introduced into the valve in the direction of the longitudinal axis.
- the method allows a gas cartridge to be filled by supplying gas along the longitudinal axis of the valve.
- a gas cartridge filled with gas is provided, from which gas can be removed via the at least one outlet opening in a direction parallel to the longitudinal axis of the valve. In this way, when gas is removed, recoil forces perpendicular to the longitudinal direction can be reduced or avoided.
- the valve has an inlet closure element, which is biased by a spring element into a closed position, in which the inlet closure element closes the filling opening, a predetermined gas pressure being applied to the filling opening in order to to move the inlet closure element into an open position.
- the prestressed inlet closure element thus forms a type of check valve, which is opened when the predetermined gas pressure at the inlet opening is exceeded.
- gas can then be introduced into the valve through the inlet opening.
- a fluid connection between the outlet opening and the environment is sealed. For example, it is possible for one or more sealing elements to rest against an outer contour of the valve housing, which seal the outlet opening.
