  • Fig. 1 shows an apparatus for providing drinkable liquids according to an embodiment of the invention.
  • the device 100 comprises a pressure vessel 110, a pressure reducer 120 and a valve 130.
  • the pressure reducer 120 and the valve 130 are designed as passages through the wall of the pressure vessel 110, so that the pressure reducer 120 and the valve 130 each have a port in the interior 112 of the Pressure vessel 110 and a connection outside of the pressure vessel 110 have.
  • the pressure vessel 110 may receive a pressurizable liquid container 102.
  • the pressure reducer 110 provides a liquid, which bears at a first pressure at a first port 122 of the pressure reducer 120, with a second pressure at a second port 124 of the pressure reducer. The first pressure is higher than the second pressure.
  • the pressure reducer 120 is arranged so that the first port 122 of the pressure reducer 120 can be connected to a pressure-deformable liquid container 102 in the interior 112 of the pressure vessel 110 and the second port 124 of the pressure reducer 120 is accessible from outside the pressure vessel.
  • liquid from a liquid container 102 which is applied to the first port 122 of the pressure reducer 120 at a high first pressure, can be supplied to the second port 124 of the pressure reducer 120 at a lower second pressure.
  • the valve 130 serves to fill at least a portion of a portion of the interior space 112 of the pressure vessel 110 remaining after receiving a pressure-deformable liquid container 102 with a gas having an overpressure, so that a liquid in a pressure-deformable liquid container 102 at the first pressure on the first port 122 of the pressure reducer 120 is applied.
  • the described device 100 provides a simple way to provide liquid, especially under water, comfortably available. For example, an easy-to-handle drinking container for underwater use can be created. But not only under water can find a device according to the concept described application. For example, cyclists or mountaineers can also benefit from being provided with drinkable liquid in such a simple manner.
  • the pressure vessel 110 is designed to be pressure-tight for an overpressure caused by the filling with the gas from the inside, as well as against water from the outside. Accordingly, the pressure reducer 120 and the valve 130 are pressure-tightly integrated into the pressure vessel 110.
  • the pressure vessel 110 may be implemented such that a pressure deformable liquid container 102 may be replaceably received.
  • the pressure vessel 110 may be multi-part, so that it can be opened and a liquid container 102 can be introduced and connected to the pressure reducer 110.
  • the pressure vessel 110 can be closed again reversibly pressure-tight.
  • the pressure deformable liquid container 102 is, for example, a replaceable disposable drinking container and therefore not part of the device 100.
  • the pressure deformable liquid container 102 may not be interchangeable or at least reusable and may be parts of the device 100 , Then, the pressure vessel 110 may for example also be made in one piece.
  • the pressure vessel 110 is at least large enough to accommodate the pressure deformable liquid container 102 therein.
  • the pressure vessel 110 may be configured to receive a pressurizable fluid container 102 having a maximum volume in a filled state of between 0.5 l and 3 l. Is preferred the pressure vessel 110 slightly larger (for example, by 10%, 50%, 100%, 200% or more larger than the liquid container 102 to be accommodated) to still provide sufficient space for filling with gas with overpressure, otherwise when emptying the liquid container 102, the overpressure of the gas would decrease too much and possibly not the entire contents of the liquid container 102 could be emptied.
  • the pressure-deformable liquid container 102 may be, for example, a conventional disposable drinking bag or reusable plastic drinking bags. Thin-walled aluminum containers can also be used, for example, as long as the gas is filled with sufficient overpressure into the interior 112 of the pressure vessel 110 in order to deform the aluminum container and thus to force the liquid out of the aluminum container.
  • the pressure-deformable liquid containers 102 are preferably plastic containers that can easily be deformed, since it can also be ensured here that almost all the liquid can be forced out of the liquid container 102, as long as the gas flows into the interior 112 of the pressure container 110 with sufficient overpressure is filled.
  • the pressure reducer 120 can be implemented in various ways. For example, a classic pressure reducer can be used with a pressure sensor and a valve in which with increasing pressure on the output side via the pressure sensor, the valve is more and more closed. As a result, the pressure on the output side can be kept constant or almost constant.
  • a flow rate limiter is used as a pressure reducer 120.
  • a flow restrictor serves to regulate a predefined, constant or nearly constant flow of liquid.
  • the flow restrictor may limit a flow of liquids such that liquid that is at a first pressure against the first port 122 of the flow restrictor 120 is provided at a second pressure to the second port 124 of the flow restrictor.
  • the first pressure does not have to be constant, but rather also depends on which overpressure the gas was filled in the remaining interior. It is crucial that the fluid is provided by the pressure reducer 120 with a constant or nearly constant second pressure at the second port 124.
  • the pressure reducer should not be confused with a pure on / off valve. With an on / off valve, either no fluid is provided or the fluid becomes heavily dependent on the level of overpressure in the remaining interior provided. This can cause drinking difficulties as well as injuries if the pressure is very high.
  • the pressure reducer 120 provides the liquid at constant or near constant pressure (with a maximum deviation of 20%, 10%, 5% or 1% of the low second pressure) as long as the overpressure in the remaining interior is higher than the pressure the pressure reducer provides the liquid.
  • the pressure reducer 120 thus limits the maximum pressure with which the liquid is provided for drinking.
  • the pressure reducer 120 may limit the maximum pressure at which the fluid is provided to 0.4 bar (second pressure), although the overpressure in the interior (and thus also the fluid at the port of the pressure reducer) e.g. greater than 2 bar.
  • the pressure reducer 120 may be realized as passing through the pressure vessel such that outside the pressure vessel no parts (e.g., drinking tube) are filled or in contact with the liquid under the high first pressure. This can ensure that, for example, bursting of a hose that is under pressure from the fluid of the high pressure side can cause injury.
  • no parts e.g., drinking tube
  • the device can then be realized so that outside the pressure vessel, the liquid occurs only at the low second pressure and only within the pressure vessel, the liquid is under the high first pressure.
  • the valve 130 serves to fill the remaining part of the inner space 112 with gas with overpressure.
  • the gas can be released again from the pressure vessel via the valve in order, for example, to exchange the liquid container 102.
  • the gas for example, air supplied by a compressor under pressure can be used.

This allows a user to see if there is still enough pressure to get fluid. Especially under water at great depths this can be important. In addition, you can before replacing or refilling the liquid container 102 detect whether there is still an overpressure in the interior 112 of the pressure vessel 110.
