Description

Container for receiving, storing and dispensing liquids and viscous substances, in particular drinking water or fuel, and its use

The present invention relates to a container for receiving, storing and dispensing liquids and viscous substances, in particular drinking water or fuel, and its use.

Such containers are well known. According to the prior art, such containers are often also used as tanks in the aerospace sector and in particular in weightless space. Aerospace aerospace containers generally have very individual and specific conditions, such as a very simple, yet compact and reliable design, the lowest possible mass, a simple and safe operating principle for conveying liquids and viscous substances in weightlessness As complete as possible liquid discharge, a space and space-saving design, optimal space utilization, no inadmissible absorption of foreign media, such as propellant gas, low production costs and the like, provided. With all this, multiple applications of such containers are often excluded due to their structural design. As a result, however, so far only solutions have been proposed which do not meet these requirements, at least not sufficiently.

For example, so-called flexible bladders, ie bubbles or diaphragms, are used predominantly for drinking water tanks. The sometimes conflicting demands for on the one hand compatibility with the common in space travel drinking water qualities (sterilization) and on the other hand elasticity for a safe deformation / folding of the bladder or the diaphragm, are currently not solved satisfactorily. On the one hand, complicated film laminates are used, which in unfavorable cases leads to delamination between the layers, which causes the Function of the film severely impaired (see, for example, Apollo program). On the other hand, monolithic membranes are used (see ATV = Automated Transfer Vehicle), wherein the Durchstellen / emptying does not always work satisfactorily due to the lack of elasticity of the material used. Due to the system, there is always a residual amount of liquid in these drinking water tanks which can not be expelled and thereby unnecessarily increases the unusable mass of a spacecraft.

For example, US 3,246,580 A discloses a rotatable fluid displacement device, such as a servo device, having two adjacent toroidal chambers and an arcuate punch element displaceable therein by means of rotational drive. Both chambers are of the same size and are each provided with a connection for introducing or discharging a fluid. Between the respective chamber and the engaging in this chamber end of the punch element is a foldable stuffing box, comparable to a flexible Bladder arranged. The foldable stuffing box acts to completely absorb the fluid in one chamber via the associated port upon displacement of the stem member and at the same time to completely expel the fluid from the other chamber via the associated port, and vice versa.

Furthermore, from US 3,446,435 A a dumbbell-shaped double-piston for ejecting a stored liquid is known, which, guided by an inner wall of a spiral liquid reservoir, with the aid of compressed gas, presses against the upstream liquid. This tank system requires increased manufacturing accuracy, especially with regard to a constant bending radius. Because the originally circular line or tank cross sections deform during bending and take on elliptical cross sections. The disadvantage is that this double piston can tilt beyond even small manufacturing inaccuracies and leaks can occur. In addition, the gap is the ses double piston, in which the connecting rod is arranged, not usable, that is filled with neither pressurized gas nor the auszubringenden liquid. This in turn leads to an increasing volume loss with increasing size of this tank system.

Finally, US Pat. No. 4,533,067 A describes a device for storing and discharging a primary fluid, which device comprises a tubular tank with two cup-shaped pistons arranged separate from one another and displaceable between an inlet opening and an outlet opening. For their displacement, the interiors of the pistons are pressurized by a secondary fluid. Each piston hangs from an extendable, folded umbrella, similar to an accordion. The screen serves as a heat shield when using hot compressed gases. The separated training of the two pistons on the one hand and the screen itself on the other hand can always lead to tilting of the piston in their displacement within the tank and thus completely abolish its functionality or at least significantly affect.

In that regard, these known containers and devices for receiving, storing and dispensing liquids and viscous substances with forced ejection have all proved to be disadvantageous due to their structural design in practice. Not least due to a large number of individual components, their design and, consequently, their production make themselves very expensive. In addition, either a complete discharge of liquids and viscous substances is not possible or a volume utilization is insufficient. Of particular disadvantage are their limited functional and reliability. In addition, multiple applications are not provided.

The present invention is therefore based on the object, a container for receiving, storing and dispensing liquids and viscous substances, in particular drinking water or fuel to provide, with which can avoid the above disadvantages, which is therefore structurally particularly simple, at the same time compact and stable and very lightweight, a high volume utilization of existing space, great flexibility in their structural design and high Austreib -Efficiency has a very high reliability and is extremely inexpensive to manufacture, and to provide its use.

This object is achieved in device-technical terms in a surprisingly simple manner by the features of claim 1.

Due to the configuration of the container according to the invention for receiving, storing and dispensing liquids and viscous substances, in particular drinking water or fuel, with a jacket and at least one partition, which is arranged in an interior of the container substantially perpendicular to the central or longitudinal axis of the container and the Interior of the container is divided into at least two approximately equal chambers, wherein the at least two chambers each have an inlet opening in the region of one end of a chamber for introducing a pressure medium and an outlet opening in the region of the other end of the same chamber for discharging and discharging the liquids and viscous Communicating substances with the environment of the container, wherein in the at least two chambers each have a piston for forming two mutually separated chamber spaces arranged and perpendicular to the central or longitudinal axis of the container and between the associated inlet opening and the outlet opening of a chamber is displaceable, and wherein the pistons of the at least two chambers via a common at least one partition wall of the container by cross / s connecting rod or connecting element rigidly rigidly connected or at least withstand and about the at least one partition and the inside of the container in the at least two chambers are guided stable against tilting, is a particularly simple, also compact and stable Construction of the container of low weight achieved. In addition, in this context, an improved center of gravity prediction can be achieved by more favorable slosh behavior, ie sloshing of the liquids and viscous substances is ruled out, which in turn is important for a design of a vehicle, in particular a spacecraft, overall. At the same time, the container according to the invention has a high (volume) utilization of available installation space. By the container according to the invention, the existing installation space is used optimally and thus achieved a considerable mass savings. Namely, if a (already existing) "gusset" skilfully exploited, at the same time the structural mass for the accommodation of the container is reduced. In addition, the container according to the invention structurally very flexibly design. The container according to the invention can be designed in any desired shape and / or size. This, in turn, opens up the most versatile possible uses. Furthermore, the invention has a very high Austreib efficiency, ie the amount of unused remaining in the container liquids and viscous substances is very low. In particular, the container according to the invention is extremely reliable in function and operation. Accordingly, a malfunction or failure of individual components due to the simple design are largely excluded. At the same time, failure due to deformations that are not conducive to "bubble" material is safely prevented. Furthermore, a residue-free cleaning and emptying can be made possible with the container according to the invention. Finally, the production of the container according to the invention is simple and due to low tolerance requirements little labor intensive and is therefore extremely inexpensive.

Further advantageous details of the container according to the invention are described in claims 2 to 22.

Of great importance for a very simple and thus cost-effective design on the one hand and a high functional Reliability as well as very good dosing accuracy on the other are the features of claim 2. Thereafter, the pistons of the at least two chambers by pressurizing at least one of the pistons of the at least two chambers by means of in the inlet openings associated chamber chamber introduced air or gas introduced as the pressure medium for Dispensing and dispensing the liquids and viscous substances from the chamber openings assigned to the outlet openings together displaceable. Accordingly, it is fundamentally sufficient already to apply one of the pistons of the at least two chambers or several of the pistons in the presence of further chambers with the pressure medium. As a rule, a pressure to be applied to the respective piston (s) can therefore be selected to be smaller.

Alternatively, however, it is readily possible, according to claim 3, the piston of the at least two chambers by pressurization of samtliche piston of the at least two chambers by means of in the inlet openings associated chamber chambers introduced air or gas introduced as a pressure medium for discharging and discharging the liquids and to move viscous substances together from the chamber openings assigned to the outlet openings.

Furthermore, it is provided according to the invention that air or gas can be introduced via the inlet openings according to claim 4. If, for example, only one of the pistons of the at least two chambers or some of the pistons is acted upon by the pressure medium in the presence of further chambers, it is possible via the inlet openings, which are assigned to those chambers in which pistons are located, to which no pressure medium acts. Air or gas from the environment of the container in the appropriate chamber chambers introduced or sucked. Likewise, air or gas can be introduced into these chamber chambers, which is / s consumed or disposed of in any other way.

Advantageously, over the Auslassoffnungen the Liquids and viscous substances according to claim 5 continuously or discontinuously from the at least two chambers ausbringbar.

Of additional advantage, the liquids and viscous substances according to claim 6 metered from the at least two chambers can be discharged via the outlet openings.

According to claim 7, the inlet openings are each arranged in the region of the one end of the at least two chambers and the outlet openings each in the region of the other end of the at least two chambers.

The same applies to the measures of claim 12, according to which the pistons of the at least two chambers are each designed such that a communication between the two separate chamber chambers of a chamber is excluded. By these measures, contact of the pressure medium is blocked with the recorded stored liquids and viscous substances. A bubble-free spreading or discharging and thus discharging the liquids and viscous substances from the container according to the invention is made possible.

Accordingly, the pistons of the at least two chambers in this context may be provided according to claim 13, preferably with a sliding seal, in particular at least one sliding seal, for Abstutzung on the inside of the container.

In the following description of various embodiments of a container 10 according to the invention for receiving, storing and dispensing liquids and viscous substances, in particular drinking water and fuel or fuel, corresponding, identical components are each provided with identical reference numerals.

The container 10 according to the invention can advantageously be used for receiving, storing and dispensing liquids and viscous substances, in particular drinking water and fuel or fuel, in vehicles, preferably in aircraft or aeronautical aircraft, for example in aircraft and spacecraft , In this context, the container 10 of the invention is particularly suitable for use in space, as liquids and viscous substances due to the weightlessness not able to automatically directed to a defined location to flow. In addition, the container 10 according to the invention can also be used in watercraft, preferably in a submarine or hovercraft, or in land vehicles, preferably in a passenger car, lorry or motorhome.

In Fig. 1 is a first embodiment of a container 10 shown according to the invention. The container 10 is formed in the form of a Torusabschnittes.

The container 10 comprises a jacket 12 and at least one partition wall 14.

The partition wall 14 of the container 10 is disposed in the interior 16 of the container 10, substantially perpendicular to the central or longitudinal axis 18 of the container 10. Furthermore, divides the partition 14, the interior 16 of the container in at least two about the same size and most preferably in equal chambers 20, 20 '.

In the embodiment of the inventive container 10 shown in FIG. 1, two chambers 20, 20 'are provided. In this case, the at least two chambers 20, 20 'each communicate via an inlet opening 22, 22' for introducing a pressure medium and an outlet opening 24, 24 'for discharging and discharging the liquids and viscous substances with the environment of the container 10. The inlet openings 22, 22 'are each arranged in the region of one end 26, 26' of a chamber 20, 20 '. In contrast, the outlet openings 24, 24 'are arranged in the region of the other or opposite end 28, 28' of the same chamber 20, 20 '.

In the exemplary embodiment shown in FIG. 1, the inlet openings 22, 22 'are located respectively at the right end 26, 26' of the chambers 20, 20 ', i. The outlet openings 24, 24 'are present at the left end 28, 28' of the chambers 20, 20 ', i. adjacent to the end-left container wall or the partition wall 14 of the container 10, mounted.

In the at least two, ie in the present execution in the two chambers 20, 20 'is in each case a piston 30, 30' arranged to two mutually separated chamber spaces 32, 34 and 32 ', 34', ie inlet-side chamber space 32, 32 'and outlet side chamber spaces 34, 34 'to form. The pistons 30, 30 'are each arranged perpendicular or substantially perpendicular to the central or longitudinal axis 18 of the container 10 and adapted to the cross section of the interior 16 thereof. The pistons 30, 30 'are displaceable between the associated inlet openings 22, 22' and outlet openings 24, 24 'of a chamber 20, 20' according to arrow 35.

The two pistons 30, 30 'of the two chambers 20, 20' are rigidly connected to each other via a common connecting rod 36, which passes through the partition wall 14 of the container 10. The connecting rod 36 is adapted to the shape of the container 10, here formed in particular bent. The central or longitudinal axis 38 of the connecting rod 36 coincides with the central or longitudinal axis 18 of the container 10. The movement of the at least two pistons 30, 30 'is strictly coupled via the connecting rod 36. The inflowing and outflowing fluid streams correspond to each other.

In a very advantageous manner, the two pistons 30, 30 'on the partition 14 on the one hand and the inside 40 of the container 10 in the two chambers 20, 20' on the other hand guided tilt-stable.

The container 10 is initially almost completely filled with appropriate liquid or corresponding viscous substance which is to be taken up, stored and dispensed during operation. In this case, the liquid or the viscous substance is located completely in the two outlet-side chamber flaps 34, 34 'of each chamber 20, 20'. The two pistons 30, 30 'are insofar completely or in the illustrated embodiment of the container 10 of FIG. 1 adjacent to the one, right end 26, 26' of the two chambers 20, 20 'retracted. In the embodiment of Fig. 1 therefore not quite because the Emlassoffnungen 22, 22 'are arranged slightly offset to illustrate the principle of operation of the container according to the invention 10 to the Auslassoffnungen 24, 24'. The dispensing or ejection or ejection of the liquid or of the viscous substance from the two outlet-side chamber spaces 34, 34 "of the chambers 20, 20 'can take place continuously or discontinuously via the outlet openings 24, 24' of the container 10. In particular, FIG inventive design of the container 10 and a metered dispensing or dispensing or expelling the liquid or the viscous substance ensured.

For this purpose, a depression of the container 10 is provided. In this case, the pistons 30, 30 'of the two chambers 20, 20' by pressurization of all or present the two pistons 30, 30 'of the two chambers 20, 20' together in the direction of the arrow 35 slidably. The pressurization takes place by means of air or gas as pressure medium via the two inlet-side chamber chambers 32, 32 ', which via the inlet openings 22, 22' and inlet lines (not shown) with a corresponding device for generating pressure, such as a pump or the like, optionally under Intermediate arrangement of a memory for the print medium (both also not shown) are connected for communication. The pressure medium in the form of air or gas is introduced via the inlet openings 22, 22 'corresponding to the arrows 42, 42' in the two inlet-side chamber chambers 32, 32 'under pressure.

Without being shown in detail, however, a common displacement of the pistons 30, 30 'of the two chambers 20, 20' in the direction of the arrow 35 is possible by merely one of the pistons 30, 30 'via the associated inlet-side chamber space 32 or 32 'is pressed or pressurized. Due to the rigid connection of the two pistons 30, 30 'with each other, ie via the connecting rod 36, there is automatically also a displacement of the unpressurized piston 30' or 30th In such a case, a binding due to formation of a negative pressure in the corresponding inlet-side chamber space 32 'and 32, respectively, the corresponding inlet opening 22' or 22 communicates with the environment, for example, to circulate ambient air into the inlet chamber 22 'or 32. lassseitigen chamber space 32 'and 32 introduce. Alternatively, a communication via the inlet lines (not shown) with a memory conceivable, from which an intermediately stored, (temporarily) to be disposed of medium, such as air with low or consumed oxygen content, etc., can be deducted.

The outlet ports 24, 24 'associated with the exhaust chamber chambers 34, 34' may, without being shown in detail, be located in exhaust conduits (not shown) for discharging the liquid or viscous substance, respectively. Via the outlet lines, the liquid or the viscous substance, for example, a metering device for taking water or drinking liquid or a separator for driving the vehicle, such as a spacecraft, fed (not shown in detail). The liquid or the viscous substance is then discharged via the outlet openings 24, 24 'of the two chambers 20, 20' according to the arrows 44, 44 '.

1, the partition 14, which subdivides the interior 16 of the container 10 into at least two chambers 20, 20 'of equal size, is designed such that a communication between the at least two chambers 20, 20' is achieved. is excluded. For this purpose, the partition wall 14, as shown schematically, is provided with a sliding seal 46, in which the connecting rod 36 is slidably mounted. The sliding seal 46 may comprise, for example, at least one sliding seal or the like or an elastic sealing element.

In addition, the pistons 30, 30 'of the at least two chambers 20, 20' are likewise each formed in such a way that communication between the two chamber chambers 32, 34 or 32 ', 34' of a chamber 20, 20 'separated from one another is excluded , For this purpose, the pistons 30, 30 'are provided with a sliding seal 48 in order to brace the pistons 30, 30' on the inner side 40 of the container 10 so as to be stable against tilting and to drive. The sliding seal 48 may in this context be provided with at least one sliding seal or the like or another elastic sealing element.

The container 10, which is shown in Fig. 1, is lightweight construction and / or corrosion resistant. The container 10 and in particular its jacket 12 is for this purpose made of metal, in particular of steel, stainless steel, aluminum, titanium, an alloy thereof and / or a combination thereof and preferably for pressure stiffening with a coating 54 made of plastic, in particular fiber-reinforced plastic, and / or fiber composite material provided. Alternatively, the container 10 and in particular its jacket 12 may also be formed entirely from plastic, in particular fiber-reinforced plastic, and / or fiber composite material.

As a result, by providing a further outlet-side chamber space 34 'in the inventive container 10 (virtually around the connecting rod 36), the volume of this chamber space 34' can also be fully utilized. In contrast to a known (single) Kolbenbehalter thus let the total available volume of space in the inventive container 10 so almost double.

The embodiment of the container 10 according to the invention, which is shown in FIG. 2, differs from the embodiment of the container 10 shown in FIG. 1 primarily in that the container is not in the form of a torus section but in the form of a Torus is formed in total.

In this way, the volume of the liquid or viscous substance which is to be stored, stored and dispensed in the container 10 is increased. In this case, the container 10 of the embodiment according to FIG. 2 comprises a total of three chambers 20, 20 ', 20 ", in which likewise three pistons 30, 30', 30" are truncated and guided so as to be stable against tilting. The pistons 30, 30 ', 30''are rigidly connected to one another via a circular connecting rod or a circular connecting element 36'. The central or longitudinal axis 38 'of the connecting element 36' in turn coincides with the central or longitudinal axis 18 of the container 10.

In contrast to the embodiment of the inventive container according to FIG. 1, moreover, the inlet openings 50, 50 ', 50 "and the outlet openings 52, 52', 52" are each radially in the partition wall 14 of the total of three chambers 20 , 20 ', 20''arranged. The inlet openings 50, 50 ', 50''and the outlet openings 52, 52', 52 '' thus extend radially 14 in the partition wall, the liquid or viscous substances from the chamber raumen 34, 34 ', 34' ^• according to the arrows 44 , 44 ', 44''are expelled by air or gas introduced into the chamber chambers 32, 32', 32 '' corresponding to the arrows 42, 42 ', 42''.

FIG. 3 schematically shows yet another embodiment of the container 10 according to the invention. Accordingly, the container 10 is configured as a tube cylinder closed at the end, in which a total of three chambers 20, 20 ', 20 "are accommodated. Each of the three chambers 20, 20 ', 20' 'is in turn associated with a piston 30, 30', 30 '', which are rigidly connected to each other via a common straight connecting rod 36 ''. The Emlassoffnungen 22, 22 ', 22' 'and the Auslassoff- openings 24, 24', 24 '' are again in shape, design, dimension and arrangement as those of the embodiment of the container of FIG. 1 formed. The central or longitudinal axis 38 '' of the connecting rod 36 '' coincides with the central or longitudinal axis 18 of the container 10.

Moreover, the embodiments of Behalters 10 according to FIGS. 1 to 3 with those of the other Figs. 1 to 3 uberem agree.

Finally, FIGS. 4A to 4C show an alternative embodiment of the embodiment of the invention shown in FIG Behmdungsgemaßen container 10, which has a rigid connection between the piston 30, 30 'and the connecting rod 36.

Accordingly, a torque-fixed connection is provided which reliably prevents tilting of the respective piston 30, 30 ', but at the same time permits a certain tolerance compensation. The connection between the pistons 30, 30 'and the connecting rod 36 is thus designed so that in each case a moment can be transmitted. It can be designed so that a lateral displacement of the connecting rod 36 relative to the associated piston 30, 30 ', and vice versa, is possible. This embodiment has the advantage that manufacturing tolerances of Behalters 10 and its jacket 12 can be compensated in this way, with further tilting of the piston 30 and 30 'is prevented.

In this case, for example, a disc-shaped element 56 is attached to the connecting rod 16. On the piston 30, 30 ', a sheet metal or the like receiving element 58 is attached, which preferably receives the disk-shaped element 56 without play and / or in which the disk-shaped element 56 in a plane parallel to the surface 60 of the piston 30, 30' translationally move ,

The present invention is not limited to the illustrated embodiment of the container 10. Thus, it is readily conceivable to form the container 10 according to the invention in the form of an ellipsoid, Cassini tanks or the like. A polygonal shape of Behalter 10 is basically possible. Finally, a torque-tight connection, with a corresponding modification of the structural design of the inventive container 10, which is shown in FIGS. 4A to 4C, can also be transferred to the embodiments of FIGS. 2 and 3, so that the pistons 30, 30 ' , 30 '' and the connecting element 36 'and / or the connecting rod 36' 'are connected to each other with a rigid torque.
