Definitions

  • the present invention relates to a valve for selectively closing and selectively opening a gas cartridge for a water carbonator, wherein the valve is adapted 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 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 CO 2 cartridges, for soda makers.
  • Such soda makers are also referred to as carbonators and typically have a gas cartridge connection via which the gas cartridge, or the valve of the gas cartridge, can be connected to the soda maker.
  • the valve of the gas cartridge can then be optionally opened via an actuating device on the soda maker in order to remove gas, in particular CO 2 , from the gas cartridge and feed it to a container with liquid to be carbonated, for example drinking water.
  • Such a valve for a gas cartridge comprises a cartridge connection opening, via which gas can be filled into and removed from a receiving space of the gas cartridge.
  • 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.
  • this valve has at least one external connection opening, 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 carbonator.
  • the object of the present invention is to provide a valve or a gas cartridge in which lateral recoil forces are reduced.
  • 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 can be filled with gas as desired.
  • 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 of the at least one gas outlet element movably arranged on the valve housing. when the gas outlet element is in the extraction position.
  • the outlet opening is 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 act parallel to the longitudinal direction. In this way, recoil forces perpendicular to the longitudinal direction can be reduced or avoided. In this respect, if the gas cartridge with the valve is arranged upright in a water carbonator, lateral forces when gas is extracted are reduced.
  • the outlet opening of the gas outlet element is arranged in the removal position such that the gas can escape in a direction away from the cartridge connection opening.
  • the valve comprises a plurality of gas outlet elements which are arranged on the valve housing so as to be movable between a rest position and a removal position and have an outlet opening, wherein the plurality of gas outlet elements protrude from the valve housing in the removal position, so that the outlet opening is arranged on the outside and 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 outlet opening is arranged inside the valve housing in the rest position. In the rest position, the outlet opening is arranged so as to be protected from environmental influences. Gas can be prevented from flowing out through the outlet opening in the rest position.
  • the outlet opening is covered in the rest position, in particular by the valve housing, so that the gas outlet element can be moved from the rest position to the removal position by an overpressure in an interior of the valve housing.
  • gas can thus be prevented from flowing out through the outlet opening.
  • the gas can cause an overpressure in the interior of the valve housing, which pushes the gas outlet element from the rest position towards the removal position.
  • the overpressure can be caused by actuating the valve, so that as a result of the actuation the pressure in the interior of the valve housing increases, as a result of this pressure increase the gas outlet element is transferred to its removal position and the gas can then flow out of the valve in the removal position of the gas outlet element.
  • the gas outlet element is movable in a direction arranged obliquely, in particular perpendicularly, to the longitudinal axis between the rest position and the removal position.

  • the interaction of the stop of the gas outlet element and the stop surface defines an end position beyond which the gas outlet element cannot be moved out of the valve housing.
  • the gas outlet element comprises a gas channel connected to the outlet opening, which has a course that is angled, in particular by 90°.
  • the gas channel within the gas outlet element initially runs from the outlet opening in a direction parallel to the longitudinal axis of the valve and bends at a bend point, in particular by 90°, so that the channel has a course after the bend point that is arranged obliquely, in particular perpendicular to the longitudinal axis of the valve.

  • the tappet can be preloaded by a spring element in a direction away from the cartridge connection opening.
  • a retaining element in particular an annular one, is arranged on the valve housing, via which the valve can be secured in a gas cartridge connection of a water carbonator.

  • 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 of the at least one gas outlet element. It is therefore not necessary to move the at least one outlet element into the removal position in order to fill the gas cartridge. Instead, the outlet element can be arranged in the rest position for filling 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, wherein the actuating element has 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 both to apply a pressure force in the direction of the longitudinal axis to activate the extraction of gas - in particular by means of an activation element of a water carbonator - and to introduce gas into the valve in the direction of the longitudinal axis during filling.
  • the valve has an inlet closure element which is prestressed by a second spring element into a closed position in which the inlet closure element closes the filling opening, wherein the second spring element is designed such that the inlet closure element by applying a predetermined gas pressure to the filling opening, it can be brought into an open position in which the filling opening is open for the introduction of gas.
  • the pre-stressed inlet closure element thus provides a filling partial valve in the manner of a check valve, which holds gas in the valve and lets in 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 pre-tensioned into a closed position in which the cartridge closure element closes a passage between the filling opening and the cartridge connection opening, wherein the cartridge closure element can be moved by the inlet closure element of the valve in the direction of an open position in which the passage between the filling opening and the cartridge connection opening is open for the introduction of gas.
  • the cartridge closure element can also be brought 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 of the at least one gas outlet element and the cartridge connection opening.
  • 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 invention further relates to a method for filling a gas cartridge as 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 outlet opening of the at least one gas outlet element in a direction parallel to the longitudinal axis of the valve.

  • the inlet closure element 24 is pushed into the position shown in the Fig. 6 shown closed position, in which the inlet closure element 24 closes the filling opening.
  • the spring element 25 is configured such that the inlet closure element 24 can be brought into an open position by applying a predetermined gas pressure to the filling opening 17, in which the filling opening 17 is opened for the introduction of gas.
  • gas can be introduced through the filling opening 17 into the interior of the valve housing 11 and then guided through the passage in the insert 26 in the direction of the cartridge connection opening 15.
  • a detailed representation of a gas outlet element 12 of a valve 10 is shown, which is connected to a gas cartridge connection of a water carbonator.
  • the gas cartridge connection comprises a sealing device 200, 200 ⁇ , which rests against the outer contour of the valve 10 and seals an area around the outlet opening 16.
  • the sealing device has an upper sealing section 200 which seals above the outlet opening 16 and a lower sealing section 200' which seals below the outlet opening 16.
  • a sealed space 201 is thus created, in which the gas flowing out of the outlet opening 16 parallel to the longitudinal direction L is received.
  • This sealed space 201 can be designed in such a way that the gas is discharged in a direction oblique to the longitudinal axis L, see arrow B.
  • the gas can then be conducted, for example via a line, to a carbonation device of the water carbonator, via which the gas can be introduced into a container filled with water.
  • FIG. 10 and 11 show conditions that occur when filling the Fig. 1 shown gas cartridge 1 can be taken in via the filling opening 17 on the side of the valve 10 opposite the cartridge connection opening 15 in order to seal a fluid connection between the outlet opening 16 of the gas outlet elements 12 and the environment. This is necessary in order to prevent an undesired escape of the gas via the outlet openings 16 when gas is introduced via the filling opening 17. Rather, the gas introduced into the valve 10 via the filling opening 17 can then be guided into the receiving space of the gas cartridge 1 via the cartridge connection opening 15.
  • the gas outlet elements 12 are fixed in their rest position via a locking element 300.
  • the locking element 300 can be arranged on the outer contour of the valve housing 11 in such a way that an undesired extension of the gas outlet element 12 is prevented.
  • the gas outlet elements 12 can be either in their rest position or - as shown - in the removal position.
  • a sealing element 301 is arranged on the outer contour of the valve housing 11, which seals the area around the outlet opening 16 from the environment.
