Description

Container for dispensing fluid, comprising a pressure control device with activation step

The known container comprises a pressure vessel in an interior space containing a fluid to be discharged and equipped with pressure regulating means. In the pressure cylinder, the first chamber is formed such that the gas is introduced at a relatively high pressure, while the outflow opening is closed by the closing member. The closure member is slightly rod-shaped and is surrounded by an O-ring in the outflow opening so as to be sealed tightly, and the rod-shaped member is formed with a circumferential groove. The second chamber facing the first chamber in the pressure cylinder is formed so as to be closed to the side base of the first chamber by a membrane to which the rod-shaped member is attached through one end, and the adjustment pressure in the second chamber is a gas. Acted by. A third chamber is formed between the first chamber and the second chamber, and the rod-shaped member extends through the third chamber and has an opening portion in which a fluid passage is formed between the third chamber and the inner space of the container.

In a known device of the third chamber, when a desired pressure such as, for example, an adjustment pressure is applied, the groove is located in the third chamber and the outflow opening is closed by a rod-shaped member. When the fluid is discharged from the interior space the internal pressure will be reduced, thus corresponding pressure in the third chamber will also be reduced. As a result, the membrane-shaped wall portion of the second chamber will deform in the direction of the first chamber, thereby further moving the rod-like member in the axial direction in the first chamber. When the groove is moved to the height of the O-ring, the gas may leak under pressure from the first chamber to the third chamber and back through the groove to the interior of the vessel. As a result, the pressure in the third chamber rises so that the membrane-shaped wall portion deforms against the adjustment pressure, thereby moving together with the rod-shaped member from the first chamber. When the rod-shaped member is hermetically enclosed by the O-ring, the gas can no longer leak out of the first chamber, and the pressure conditions in the third chamber and in the interior space are again equal to the desired pressure, here the regulating pressure. .

This known container has the disadvantage that when the pressure is adjusted already the control pressure is established in the second chamber and furthermore the adjusting means acts directly on the closing member so that the gas flows out of the first chamber. This is because the pressure of the third chamber will always be lower than the adjustment pressure of the second chamber when the adjustment takes place under normal pressure. To clarify this problem, it is intended to attach a pressure regulator so that the adjustment pressure is equilibrated and fill the vessel under excess pressure, but this is technically complicated and disadvantageous.

The present invention relates to a container of the type described in the preamble of the claim, which container is known from French patent A-2690142.

It is an object of the present invention to provide a container of the type described in the preamble which retains the advantages while eliminating the disadvantages described above. In the end, the device according to the invention is characterized by the features according to claim 1.

In the device according to the invention, the advantage is achieved that the adjusting means is at least functionally separated from the closing member before use. This means, for example, that the movement of the adjusting means does not move the closing member to the open position at the pressure of the third chamber, which is relatively low relative to the adjusting pressure, during assembly and filling of the container, which is always closed before use. It means. Only when a certain operating step is carried out the desired adjustment pressure is obtained in the second chamber during use, and when the pressure in the third chamber decreases relative to the adjustment pressure, as described in the introduction, the closing member is preferred to open the pressure fluid. A functional coupling is obtained between the control means and the closure member so that it can be moved to a position. Then, the operation step is deliberately performed in order for the pressure regulation to be applied.

In addition, the pressure regulation used in the device according to the invention has the advantage that the pressure medium can be easily stored and transported without the risk of flowing out of the first chamber. Thus, important technical safety and economic advantages are achieved. Furthermore, the device according to the invention can be assembled and filled at a particularly preferred normal ambient pressure, since it allows the use of conventional assemblies and filling lines and no special pressure equipment is required.

In a first preferred embodiment, the container according to the invention is characterized by the feature according to claim 2.

In this embodiment, the adjusting means of the first position is free to move relative to the closing member over a selected distance without the closing member being operated. This means that the volume of the second chamber can change within the selected range, for example, as a result of the pressure change without the pressure fluid leaking out of the first chamber. The actuating step allows the closing member to act at least temporarily through an open passage between the first chamber and the third chamber to actuate the control means when the volume change of the second chamber is particularly increased. The coupling means can be moved to the second position to be engaged. For example, the container can be filled and the pressure regulating device can be fitted with a coupling means in the first position so that unwanted discharge of the pressure fluid from the first chamber can be prevented while the container can be ready for use through the operating steps. The actuation step may be chosen such that this step may be influenced by the consumer himself and / or may be performed by the manufacturer or retailer.

In this embodiment, the first and second coupling means are formed such that they can be moved to a first position where they are functionally separated so that the first portion can move relatively freely relative to the second portion without operating the closure member. . When only the first and second engagement means are moved to the second position where they are functionally coupled, the closure member can be moved to the open position by the movement of the adjustment means. The required operating steps can be obtained, for example, by mechanical means such as vigorous movement of the first and second parts relative to each other, but preferably at least as much as the regulating pressure of the second chamber while using the pressure of the third chamber. Obtained by the air method by temporarily raising above the high working pressure.

It is desirable for the pressure of the second chamber to be at least approximately equal to 1 bar, approximately equal to the ambient pressure, before the operating step, in which the movable part of the wall is put in too much and further extension.

The invention also relates to a process for the manufacture of a container adapted to discharge a fluid under a substantially constant pressure, characterized by the feature according to claim 6.

Simply in this way, the pressure regulator can be filled with a pressure medium, such as a gas, and in turn can be formed without the risk of an undesirable flow of pressure fluid from the first chamber into the surroundings. In fact, the closing member always keeps the first chamber closed while the adjusting means cannot at least open the first chamber yet. When only the adjusting means is functionally coupled to the closing member via the actuation step, the pressure regulation can be formed by the opening and closing of the controlled closing member.

In a first preferred embodiment, the method according to the invention is also characterized by the feature according to claim 7.

By having at least a second part adjacent the closure member for the container and mounting the first part of the container at some distance from the second part, they are separated from the container before use. Further, by making the second part movable relative to the first part, the pressure regulator can be operated by engaging the first and second parts through movement. By means of the closure members interacting with each other, the adjusting means will form the desired internal pressure of the container. In this case, when the container is filled, the pressure can already be applied to the internal space which is approximately equal to the adjusting pressure of the second chamber. Thus, the adjusting means will be in a neutral position before engaging the first and second parts.

In another preferred embodiment, the method according to the invention is characterized by claim 9.

In this embodiment the pressure in the interior space of the vessel is temporarily controlled, for example by introducing pressure gas, particularly significant additional carbon dioxide, into the headspace of the vessel such that the control means is operated and moved to an active and functionally connected position in communication with the closure member. Mostly elevated. Since the headspace will usually be relatively small, only a relatively small amount of gas needs to be additionally introduced so that the pressure decreases relatively quickly, i.e. it can be easily absorbed by the beverage. Then, the opening part and the closing part of the closing member are adjusted to be operated by the pressure regulating device. In addition, it is evident that for example, a deformation of the wall portion of the container in the direction of the inner space or the expansion of the balloon-shaped member of the container can reduce the head space to obtain a desired increase in pressure.

The required operating steps can be easily carried out by the manufacturer, for example, by introducing significant carbon dioxide or by modifying the walls of the container immediately after filling the container and during or after closing the container. In addition, means may be provided for the consumer to carry out this operating step, for example by means of a small or small device corresponding to the internal or external gas cartridge and the opening of the discharge means or the like.

As the pressure fluid of the device or method according to the invention, preferably, the gas is in particular carbon dioxide or a gas containing carbon dioxide, but other pressure fluids such as liquids can also be used. In addition, the pressure fluid can be obtained by chemically gathering acids such as calcium, (heavy) carbonate, and citric acid, and many modifications are possible. In this connection, for example, the (heavy) carbonate or other calcium salt product can be stored in a third chamber at least on the opposite side of the closure member.

Another embodiment and method of a container according to the invention is described in the other dependent claims.

For clarity of the invention, embodiments of the vessel and the pressure regulating device and method will be further described with reference to the drawings.

1 is a schematic side cross-sectional view of a container 1 in the form of a generally cylindrical can in which a beverage 2 is to be placed in the interior space 4. The head space 6 of the vessel 1 can be filled with carbon dioxide gas, for example, and the pressure regulating device 8 of the vessel 1 comprises a pressure vessel 10, a valve assembly 12 and an open outlet 14. Is made of. The gas is stored at a relatively high pressure in the pressure vessel 10 which will be described further below. By the valve assembly 12 which will be described further below, the gas may be introduced into the inner space 4 of the vessel 1 for regulating the pressure from the pressure vessel 10 via the pressure regulator 8. In the embodiment shown in FIG. 1, the side wall of the container 1 is arranged with a tab 16 through which the beverage 2 can be discharged from the interior space 4.

In the side cross-sectional view of FIG. 2 there is shown a part of a pressure regulating device 8 filed in the same and described in more detail in a Dutch patent application entitled "A vessel with a pressure regulating device for discharging fluid". This embodiment is intended to illustrate the general principle of operation of such a pressure regulating device 8.

In this embodiment, the pressure regulating device 8 consists of a first housing 18, an intermediate portion 22 and a second housing 52. The valve 94 in the middle portion 22 is conventionally used for spray cans such as aerosol containers and similar devices, which valves are known in practice. Although a suitable embodiment of the valve 94 is shown in FIG. 2, other types of valves can of course also be used in the pressure regulator according to the invention. Thus, for example, a female valve or a tilting valve may be used instead of the male valve shown. In the embodiment shown, the valve 94 is in tight connection with the intermediate portion 22, with the third chamber 86 having a fourth chamber 86 in which the compression spring 42 is received therein by biasing means. Housing 95, whereby the valve is inclined to the closed position. The rod-shaped member 96 passes through the collar 98 and is partitioned between the connecting portion 22 and the upper end of the spring 42 and extends to a point outside the connecting portion 22. A portion located outside the connecting portion 22 is formed in the form of a hole in which the shaft bore 36 is blocked, and a radial bore 37 is formed on the collar 98 and ends in the shaft bore 36. In the position shown, the radial bore 37 is closed by the sealing ring 39 of the intermediate portion 22. The second housing 52 on the intermediate part 22 is mounted to the appropriate snap means 48, 50. Inside the second housing 52, the second chamber 60 is separated from the third chamber 62 by an axially movable piston 58, and the third chamber 62 opens the open outlet 64. It communicates with the internal space 4 of the container 1 through. At the bottom of the piston 58, a cylindrical portion 95 is formed with a shaft bore 98, which can be fitted and fixed appropriately on the upper end of the rod-shaped member 96. A collar 99 is formed in the shaft bore 98 supported at the upper end of the rod-shaped member 96 at the side base portion of the piston 58. The radial bores 97 extend from the shaft bore 98 such that the shaft bore 98 is in fluid communication with the third chamber 62.

As explained in more detail in the same Dutch patent application described above, the adjustment pressure in the second chamber 60 is reduced when the pressure in the third chamber 62 and the interior space 4 decreases below the desired minimum pressure. ) Increases in volume and at least the piston 58 moves, and the rod-shaped member 96 moves downward against the spring pressure of the spring 42 in the direction of the first chamber 24. Accordingly, the first chamber 24 and the third chamber via the open passage 28, the fourth chamber 86, the radial bore 37, the shaft bores 36 and 98, and the radial bores 97. Communication of the fluid is achieved between the chambers 62.

In the first chamber, an appropriate amount of gaseous pressure medium, in particular carbon dioxide, is stored under overpressure. The first chamber 24 in the first housing 18 is preferably usually of activated carbon, such as activated carbon fiber 26, which has a high suction and suction force, for example against pressure gas, especially for gases containing carbon dioxide or carbon dioxide. Is filled. As a result, a particularly large amount of pressure gas can be filled in the first chamber 24 in proportion to the pressure attainable. This provides the advantage that the first chamber 24 can be relatively small but contain sufficient gas. The use of such activated carbon is described in the Dutch patent application 1009654, which the applicant has already filed, which is introduced here by reference only.

Other pressure fluids may be included in the first chamber, such as, for example, liquid under pressure or instead of carbon dioxide. Alternatively, the reactant may be included in the first chamber capable of reacting with the second reactant to form a pressure medium such as carbon dioxide. These may be for example acid products and citric acid products such as citric acid and (heavy) carbonate, while the second reaction element is stored in the first chamber or the third chamber and at least the closing member away from the first chamber when the pressure decreases. It can react only in the third chamber on the side. In this case, the reaction between the elements does not occur until the closing member is temporarily adjusted into the open position when the pressure decreases in the interior space of the vessel and is sufficient to move the elements together or to form the desired gas. Pressure changes occur. Other reactions can also occur appropriately, especially depending on the medium to be discharged.

When fluid communication is established between the first chamber 24 and the third chamber 62 described above, the gas flows out under pressure and flows through the open passage 64 into the interior space 4 of the vessel, thus. The internal pressure will increase. Moreover, the pressure of the third chamber 62 will rise so that the piston 58 moves back up, so that the pressure increase of the second chamber 60 causes the rod-shaped member to move back to the position shown in FIG. And smaller until the radial opening 37 is closed by the ring 39. Thus, with such a pressure regulator, the desired pressure in the interior space 4 of the vessel 2 will be maintained continuously. In fact, if the fluid is discharged from the vessel, the pressure in the interior space 4 and the third chamber 62 will decrease and the piston will move down for the pressure regulation described above.

In the illustrated embodiment, the piston 58 is coupled to the rod-shaped member 96 when the second housing 52 is engaged with the first housing 18. This makes the active and functional engagement between the piston 58 and the valve 94 flexible. This means that when the formed assembly is not stored and assembled under a sufficiently large ambient pressure, the valve 94 is adjusted to open immediately and gas will flow around in the first chamber 24.

In order to eliminate this drawback, a container according to the invention is proposed, which functionally separates the piston 58 or similar adjusting means from the valve 94 or similar closing member, and removes this functional coupling only after the operating step. It is supposed to be effective. With reference to FIGS. 3 to 12 a number of exemplary embodiments of such adjusting devices with actuation steps will be described, wherein the adjusting means used therein is for example the Dutch described above filed on the same date by the applicant. It may be represented in various ways as shown in the patent application.

3 shows a portion of a preferred embodiment of the container 101 according to the invention in cross section with a portion of a pressure regulator as shown for example in FIGS. 1 and 2. Frequently, it will be apparent that other embodiments of the pressure regulating device according to the invention in the container 101 can also be used.

3a shows a portion of the wall 103 of the container 101 with an opening 115 therein, in which a movable closure means 117 is sealed with a rubber ring 119 or similar sealing member. Are interlocked and accommodated. The first housing 118 of the pressure regulating device 108 is positioned so that the pressure regulating device 108 is mounted and mounted at a distance slightly below the opening 115 by suitable suspension means 121. The first chamber side base in the closing means 117 has a space 123 in which the second housing 152 can be fixed to be tightened slightly so that the sub coupling means 150 extends at a distance from the other coupling means 148. ) Is formed concave. Next, the axial bore 198 is similarly positioned at a distance from the rod-shaped member 196. In this position, the valve 194 cannot be pressurized and at least cannot be opened such that no gas can flow from the first chamber 124 into the interior space 104.

The closing member 117 is formed with a discharge channel 125, the one end is connected to the cavity 123 and the other end may be connected to the hose 127, for example, can be connected to the tapping means or similar devices. have. The cavity is formed with a series of ribs 128, which keep the end wall 156 of the second housing 152 away from the walls of the cavity 123 in the axial and radial directions. Thus, during use, the beverage 2 can flow past the second housing 152 into the discharge channel 125 regardless of the position of the closure means 117.

In order to prepare for use of the pressure regulating device 108 in the container 101 according to FIG. 3, the closing means 117 has only to be moved in the direction of the interior space 104, and thus the second means by the coupling means 148, 150. The housing 152 is fixedly pressed onto the first housing 118, and at the same time the shaft bore 198 is pressed onto the rod-shaped member 196. This ready state is shown in Figure 3b. The closing means 117 can be moved back up but can optionally be locked in the pushed down position. In the state shown in FIG. 3B, the pressure of the inner space 104 will be adjusted in the manner described below according to the adjustment pressure of the second chamber 160 and the pressure of the third chamber 162.

In a variant of the embodiment according to FIG. 3, which is not shown, the closing means 117 consists of a valve which closes the discharge channel 125 in the state shown in FIGS. This valve opens automatically when the closing means 117 of FIG. 3A or 3B is pushed down, thereby achieving the advantage that the closing means 117 can act simultaneously as the tab 116. However, outlet channel 125 may also be removed when other tabs are formed, such as shown in FIG. 1.

In addition, in the embodiment shown in FIG. 3, the piston may be connected to the rod-shaped member 196 such that the chamber 160 is reduced only prior to operation and is reduced only when the closing means 117 is pressed down.

4 shows that the housing 252 for the second chamber 260 is connected to the valve 294, while the piston 258 extends to the open end of the housing 252 away from the first chamber 224 and the wall of the container. Another embodiment that can be fixed in two positions relative to 203 is shown. On the left side of FIG. 4, the piston 258 is fixed in an upper position such that the second chamber 260 is relatively large and generally pressure free, and the housing 252 remains stationary. By pushing the piston 258 to the position shown on the right side of FIG. 4, the piston is supported on the wall 203 by the fingers 253, and the volume of the second chamber 260 is significantly such that the desired adjustment pressure is obtained. Is reduced. The change in the pressure of the inner space 204 to a value below the adjustment pressure causes the housing 252 to immediately move downwardly from the piston 258, so that the valve 294 can be discharged from the first chamber 224. Will be activated.

FIG. 5 shows an embodiment of a control device according to the invention in which the first chamber 324 is provided with a valve 394, which is a male valve in the illustrated embodiment, although this valve is a female valve. It can also be a tilting valve. The second chamber 360 is formed in a housing 352 in which the piston 358 is suitably fitted and accommodated with the sealing O-ring 370. The stem 366 is firmly connected with the piston 358 and extends in the direction of the valve 394, and the free end 367 of the stem 366 is not in contact with the valve 394. The generally cylindrical intermediate portion 369 has a first end secured to the valve 394 and a plurality of open passages that form a fluid connection between the first chamber 324 and the third chamber 304 when the valve is opened. A circumferential wall with 397 is provided. The intermediate portion 369 is formed adjacent to the second open end away from the first chamber with an expanded portion 371 with a shoulder 373. The free end 367 of the stem 366 has elastic fingers 377 extending into the bore 375 of the intermediate portion 369 and inclined outward. In the first position shown in FIG. 5, the fingers 377 are in contact with the inside of the narrower portion of the bore 375 between the valve 394 and the shoulder 373. This is the minimum distance the piston 358 is determined on the one hand between the free end 367 and the valve 394 and on the other hand the distance determined by the position of the fingers 377 and the shoulder 373. This means that it can be moved freely. Indeed, when the piston 358 is further moved in the housing 352 in the direction of the end wall 356 to or above the distance indicated by the dashed line, the free ends of the fingers 377 are subsequently generated. When descending movements occur they will be on the shoulder 373 and move outward so that they are caught on the upper surface of the shoulder 373. Accordingly, the fingers 377 and the shoulder 373 form the first and second coupling means. When the piston 358 is moved down in the position indicated by the dashed line, as the volume of the second chamber 360 increases, the intermediate portion 369 will move down with it and thus the valve 394 will open. .

From the position of the piston 358 shown by the solid line in FIG. 5, which disables the valve 394, the valve can be moved to the use position by an actuation step. As a result, for example, the pressure in the third chamber 304 temporarily rises from the outside so that the piston 358 moves up to the position indicated by the dotted line, so that the adjustment pressure in the second chamber 360 is at least approximated. As a result, the fingers 377 are moved over the shoulder 373 and an operating position when used is obtained. Again, this may be accomplished, for example, by mechanically pushing the piston 358 up to the position indicated by the dashed line.

6 schematically illustrates another embodiment in which a bore 475 is formed in the stem 466, which is connected to the piston 458 such that the bore 475 has a closed end 479. have. The bore 475 adjacent the open end 481 has an enlarged portion 471 such that the shoulder 473 is formed at a distance from the blocked end 479. The intermediate portion 469 has a first end fixed to the valve 494, which in this embodiment is a female valve, and fluid connection between the first chamber 424 of the container and the interior space 404 when the valve is opened. A passage 497 is formed, and the middle portion 469 has elastic fingers 477 inclined outward. When the free ends of the fingers 477 are secured together, they can slide into the relatively narrow portion of the bore 475 between the closed end 479 and the shoulder 473, and the fingers 477 move the piston 458. It can move freely in the longitudinal direction to be possible without this actuated valve 494. Only when the volume of the chamber 460 is significantly reduced and the piston is moved so that the free ends 483 of the fingers 477 are moved below the shoulder 473, the fingers 477 have the free ends 483 at the shoulders 473. Can expand to catch). In this position, movement of the piston 458 in the direction of the valve 494 ends at the intermediate portion 469 which is pressed down along it to open the valve 494. A first, second position of the first and second engagement means formed on the stem 466, and at least the shoulder 473, the intermediate portion 469, and at least the fingers 477 are connected to the separated first position; It is indicated by the dotted line at the location.

7 shows a part of the adjusting means according to FIG. 6 with the stem 466 in which the piston 458 is divided into two parts 466a and 466b. The first cylindrical portion 466a is firmly connected to the piston 458 and has a flange 461 extending inwardly with an opening at the free end. The second portion 466b of the stem 466 extends through the opening at an end located within the first stem portion 466a and provides adequate guidance when the second stem portion 466b is moved to the maximum. And an extension that abuts against the flange 461. The bore 475 of the second stem portion 466b forms a shoulder 473 by having an extension adjacent to the outer free end. Although not shown in FIG. 7, the fingers 477 of the intermediate portion 469 as shown in FIG. 6 can be received back in the bores 475 in the first and second positions. In this embodiment, the piston 458 allows the second stem portion 466b to move freely relative to the first stem portion 466a relative to the distance S, thereby making the valve 494 inoperable. The advantage of obtaining more free movement with the connecting means 477,473 of the position is achieved. The valve 494 can be actuated only when the inner end of the second stem portion 466b is in contact with the piston 458a and the fingers 477 are in contact with the shoulder 473.

8 shows another embodiment of a piston 458 with a stem 466 for use in the pressure regulator according to FIG. 6. Ridges 485 in the extensions 471 of the bores 475 extend from the shoulders 473 in the direction away from the piston 458 and the closed end 479 of the bores 475, which are ridges 485. ) Is included in extension 471. In this embodiment, the free ends 483 of the fingers 477 will have to pass through the edge 487 of the ridge 485 to be able to contact the shoulder 473 from the separated first position to the connected second position. . This achieves the advantage that the piston 458 has to be moved relative to the housing 425 over a relatively large distance, ie the volume of the second chamber 460 is significantly reduced, which is clearly more necessary for the desired regulating pressure. Do. In addition, this means that the chances of undesirable operation are significantly reduced and safety is further improved.

9 and 9a are cutaway side cross-sectional and partial front views, showing another embodiment of a control means for a container according to the invention. In this embodiment, an intermediate portion 569 having a passage 597 is fixed to the valve 594 of the first chamber 524, and an elastic finger 577 is mounted on the intermediate portion 569. In the position shown in FIG. 9, the elastic finger 577 is selectively inclined to the left, and the reason is described below. The piston 558 with the piston ring 570 is attached with a stem 566 with two bores positioned laterally with respect to each other. In FIG. 9, the first bore 575a located on the left side has a depth S ₁ , and the second bore 575b located on the right side has a depth S ₂ greater than the depth S ₁ . Having depth, the depth begins at the open end 581 of the bores 575 away from the piston 558. The elastic finger 577 at the end has a head 591 represented by a cross bar in the illustrated embodiment. The first bore 575a is separated from the second bore 575b by a partition 595 that terminates at a distance away from the open end 581. A slightly flexible flap 593 adjacent the open end 581 of the bore is connected to the side of the first bore 575a and extends inclined with respect to the opposing wall of the second bore 575b. The flap 593 is formed with a slot 593a through which the finger 577 extends, and the head 591 is in contact with the sides of the fork-shaped flap 593 ends of the piston 558.

A separate first position is shown in FIG. 9, where the head 591 extends into the second bore 575b between the blocked end and the flap 593, and the piston 558 is the end of the partition 595. It is free to move beyond the height determined by the distance between 599 and the closed end 579b of the second bore 575b. When the piston 558 is moved up until the head 591 extends below the edge 599, the head will be guided into the first bore 575a by the flap 593. Subsequently, when the piston 558 is moved down again, the head 591 is received in the first bore 575a and contacts the closed end 579a of the first bore 575a. When the piston 558 moves further down the valve 594 will be actuated via the finger 577 and the flap 593 prevents the possibility that the head 591 will fall out of the bore 575. Moreover, the flap 593 is located very close to the edge 599 of the partition 595 so that the head 591 will not move easily between them as the head moves up along the flap 593. As a result, the head 591 is prevented from moving back to the second bore 575b. Further, the flap 593 may optionally be omitted when the finger 579 is sufficiently inclined in the direction of the first bore 575a.

10 and 10a are, respectively, a partial side cross-sectional view and a perspective view, showing another embodiment of the actuating device according to the invention, which is particularly suitable for use with a tilting valve. These tilting valves, in which the open passage can be opened or closed by tilting the operating system, are actually known and are not described further here. In this embodiment, the tilting valve 694 connected with the first chamber 624 has an actuation stem 669 with an expansion head 667, and the head 667 preferably has a convex top. The housing 652 of the second chamber 660 houses a piston 658 to which the stem 666 is fixed. The piston 658 has a direction of movement P which extends at an angle, preferably at right angles, to the center line L of the tilting valve 694 and the actuation stem 669, and the stem 666 of the piston 658. The first fork 690 and the second fork 692 are provided. FIG. 10A is a perspective view of a stem with a first fork 690 and a second fork 692, shown with an actuation stem 669 with an extension head 667. The first fork 690 and the second fork 692 are located in parallel planes at some distance from each other. In the neutral position shown in FIG. 10A this distance is indicated as D ₁ . Each fork 690,692 consists of two split ends, with intervening slots 690a, 690b, each of which slots open at the end away from the piston 658. These slots 690a and 690b have a width that is greater than the thickness of the actuation system 669 but less than the width of the head 667. Thus, the two forks 690 and 692 can slide over the actuation system 669 between the valve 694 and the head 667. The first fork 690 is shorter than the second fork 692 as in the slots formed therein, and the closed end 679a of the first slot 690a is at a distance away from the piston 658. It is greater than the distance between the piston and the closed end of the second slot 690b.

Figure 10 shows the upper part of the actuator in a separate first position, in which a first fork 690 that is somewhat elastically deformed is supported over the knob 667. The deformation of the materials and the fork is selected such that movement of the piston 658 in the direction P is possible without the operating system 669 and is thus performed. From this position, the device can be operated by moving the piston 658 in the direction of the end wall 656 so that the free end of the first fork 690 can pass through the head 667. The elastic deformation stress of the first fork 690 will be returned to the plane V to extend below the bottom of the head 667. As a result, the actuation stem 669 will be received in the first slot 690a when the piston 658 returns in the direction of the valve 694. When the piston 658 moves further in the direction away from the end wall 656 and the volume of the chamber 660 increases, the blocked end 679a is in contact with the actuation stem 669 and further moved longitudinally relative to the top. It moves along the operating system 669 to be inclined with respect to the axis (L). Accordingly, the tilting valve 694 will be opened, and gas may flow from the first chamber 624 into the internal space 604. When the pressure in the interior space 604 increases, the piston 658 moves backwards, thereby reducing the second chamber 660 so that the tilting valve 694 can be returned to the closed position. Optionally, the guide ring 667a of the actuation stem 669 between the valve 624 and the head 667 has at least a second fork 692 guided with the valve 694, as indicated by the dashed line in FIG. Guided between rings 667a may be obtained to obtain a much better position.

11 shows a simple embodiment of a device according to the invention for operating the tilting valve 794. In this embodiment, the piston 758 defining the second chamber 760 in the housing 752 consists of a stem 766 having an obliquely formed free end 781. The tilting valve 794 of the first chamber 724 is similarly formed with an engaging portion 769 having a free end 783 formed at an oblique angle, and the stem 766 is guided by a guide portion 757. 752). When expanding the second chamber 760, the stem 766 is moved downward in the direction of the tilting valve 794. Interacting obliquely formed ends 781 and 783 will cause the tilting valve 794 to tilt from the closed position to the open position. This method may also be used in the embodiments shown above when the tilting valves are used in place of the valves or the actuating means shown.

Fig. 12 shows another embodiment of the pressure regulating device 808 according to the present invention, in which the recess 872 of the first housing 818 is provided with an opening passage 828 with a shaft bore 836. ) Is formed. The closing member 840 in the form of a ball is pushed to the seating portion 834 by the inclined means 842, extending from the closing member 840 through the shaft bore 836 to the recess 872. The pin 880 is provided. The inclined means 842 and the closing member 840 are housed in a fourth chamber 886 with inlet openings 888 ending in the first chamber 824. Accordingly, the recess 872 can be located at a relatively large distance from the wall of the first housing 818. In this embodiment, the second housing 852 is received in the recess 872 to have an end wall 856 supported at the bottom 878 of the recess. In this embodiment, the piston 858 is a cylinder having an outer circumference that corresponds approximately to the inner circumference of the second housing 852 with an intervening portion of the piston ring 870 to be fitted or a similar gas and liquid imparting seal. The second chamber 860 is further formed between the piston 858 and the end wall 856. At the end of the piston 858 away from the second chamber 860 is an adjusting means 866 formed as a disk 867 with cutting cone edges 890 and 892. This disk 867 has, for example, an outer diameter approximately corresponding to the inner diameter of the recess 872, while the minimum diameter of the truncated conical edges 890, 892 is approximately equal to the diameter of the piston 858.

A lower conical edge 892 having a piston 858 in a neutral position, ie a separated position, at which a low pressure in the second chamber 860 acts, is disposed on the upper side of the pin 880. Thus, the closing member 840 cannot be actuated by the piston 858 because it is pushed out by the spring 842. The piston 858 will be pushed down when the pressure is significantly raised at least temporarily in the third chamber 862, thereby reducing the second chamber 860 and raising the pressure therein. The piston 858 will then be temporarily inflated and pushed past the pin 880 opposite the spring 842. After the piston 858 has passed, the closing member 840 will be pushed back to the closed position so that the regulating device 808 is activated. When the pressure in the third chamber 862 is again reduced below the adjustment pressure, the piston 858 will be pushed upwards, thereby increasing the pressure in the third chamber 862 and in the interior space of the vessel. A fluid connection is formed between the first chamber 824, the opening 888, the fourth chamber 886, and the outflow opening 828. When the pressure in the inner space is sufficiently raised again, the piston 858 is pushed back to the position shown in FIG. 12 and the closing member is closed again.

In principle, the actuating devices according to the invention provide for uncontrollable flow of gas from the first chamber to the third chamber when the regulating pressure in the second chamber drops, for example by leakage, and in the container at least in the third chamber. The actuation means is forced to the closed position to simply and effectively prevent the rise in pressure. Thus, the safety of the container according to the invention, which consists of at least the pressure regulator to be used therein, is even more improved.
