HIGH-PRESSURE COMPRESSOR AND SYSTEM WITH A HIGH-PRESSURE COMPRESSOR

Description

[0001] A high-pressure compressor and a system with a high-pressure compressor are described, which are designed to compress a gas or gas mixture. background

[0002] According to the general technical understanding, "high pressure" refers to the high-pressure compression of gases and gas mixtures at a compression of 40 bar or more above atmospheric pressure.

[0003] The high-pressure compressor and system described herein can be used for the high-pressure compression of flammable or oxidizing gases or gas mixtures. An example of a flammable gas is hydrogen. An example of an oxidizing gas is oxygen. Flammable or oxidizing gas mixtures can contain hydrogen and oxygen.

[0004] Various applications require gases and gas mixtures at high pressures. In some cases, these pressures range from several hundred bar to over 1000 bar. For example, applications in energy-generating facilities or mobile applications (e.g., vehicles) require gases or gas mixtures at pressures of several hundred bar. Difficulties arise in the compression of the gases or gas mixtures, and conventional solutions have disadvantages. State of the art

[0005] Known compressors for gases and gas mixtures, for example, are designed as piston compressors and feature a linearly movable piston that compresses a gas or gas mixture introduced into a receiving chamber by reducing the size of the receiving chamber, thus compressing it. The compressed gas or gas mixture is then discharged and fed to a specific application.

[0006] Such piston compressors are particularly disadvantageous because, due to the moving piston, a seal is provided that seals the piston against a wall bordering the receiving chamber. However, this seal cannot provide a complete seal because there is constant movement between the components to be sealed, and it is subject to enormous wear due to the frequent movement.

[0007] Furthermore, such a compressor requires a lot of installation space - depending on the compression ratio.

[0008] FR 787 226 A discloses a compressor or diaphragm pump intended for the compression of gases, wherein a diaphragm oscillates in a generally biconical chamber. The diaphragm is preferably designed as a metal diaphragm and arranged between two plates. Both the metal diaphragm and the plates have concentric, annular corrugations. Radial grooves for the removal of gases and the distribution of the liquid, corresponding to the profile of these corrugations, are open for the supply and return of the liquid in the upper and lower parts of the corrugations of the plate.

[0009] FR 46 022 E is a subsequent application to FR 787 226 A and indicates that the metal membrane now has concentric annular waves, while the surface of the plates facing the membrane is smooth, i.e., free of waves.

[0010] DE 199 01 893 C1 discloses a diaphragm pump with a hydraulically driven diaphragm. The diaphragm is designed to be wave-shaped in the radial direction. The wavelength and / or amplitude of the wave-shaped diaphragm varies in the radial direction. Task

[0011] In contrast, the task is to provide a solution for high-pressure compression of gases and gas mixtures that both eliminates the disadvantages of the prior art and provides an alternative to the prior art that is simple in design and allows for high compression of gases and gas mixtures in a small installation space. Thus, a solution for high-pressure compression is to be provided that does not have any moving components that primarily serve for compression and are in contact with the environment. Solution

[0012] The above-mentioned object is achieved by a high-pressure compressor having the features of patent claim 1.

[0013] The high-pressure compressor is designed as a diaphragm compressor and thus compresses the gas or gas mixture introduced into the media chamber through the deformation of the diaphragm. Advantageously compared to piston compressors, such a diaphragm compressor does not have a seal connected to moving components, thus eliminating leakage problems. The diaphragm can, for example, be tightly installed in the housing, with one or more additional sealing means being provided. For example, the diaphragm can be clamped between two plates, with sealing discs or rings provided between the housing plates and the metal diaphragm. However, such sealing means are not mandatory.

[0014] The high-pressure compressor is designed so that, in a first neutral position, the diaphragm is in contact with the inner wall of the compressor chamber. Thus, the space available for introducing the gas or gas mixture encompasses both the media chamber and the compressor chamber. The entire volume of the high-pressure compressor is thus available for compression.

[0015] After a gas or gas mixture is introduced through at least one second connection, the supply is interrupted and the line is sealed. Compression then occurs, with an incompressible medium (e.g., water, (hydraulic) oil, etc.) being introduced into the media chamber through at least one first connection. The pressure exerted on the diaphragm via the medium corresponds to the pressure on the gas or gas mixture side, resulting in compression within the housing of the high-pressure compressor without differential pressure. This means that the pressure acting on the diaphragm within the housing is equal on both sides. As soon as the amount of incompressible medium exceeds a threshold value, the metal diaphragm "snaps over," causing the diaphragm to deform.The threshold value is determined according to the dimensions of the housing and the media chamber as well as the compressor chamber, the material for the membrane, the amount of gas or gas mixture introduced and the prevailing pressure across the medium as well as the design of the membrane.

[0016] For this purpose, the diaphragm is designed to allow snap-on action, which represents a significant advantage over known compressor designs. In particular, this allows the diaphragm to be deformed by the incompressible medium until it rests against, or almost completely against, an inner wall of the compressor chamber. This achieves high compression because the gas or gas mixture can be compressed by essentially the entire volume of the high-pressure compressor, consisting of the volume of the media chamber and the volume of the compressor chamber. This results in higher compression than with known devices.

[0017] The deformation of the membrane can be achieved by stretching the metal membrane, whereby the membrane is designed accordingly with regard to its construction and / or internal structure so that the required deformation is achieved.

[0018] Further advantageous embodiments result from further developments which are defined by the subclaims.

[0019] In further embodiments, the compressor chamber and the media chamber can have essentially equal volumes. According to the invention, the membrane can be structured to allow the metal membrane to "snap" and deform. The structure supports the "snap" and enables deformation. Snapping can occur suddenly or gradually.

[0020] Structured training encompasses all measures that affect the deformation of the membrane in at least one area by influencing its material. For example, structures can be achieved through mechanical deformation or by changing the internal structure of the metal or metal alloy of the membrane.

[0021] In further embodiments, the membrane can have radially extending elevations and depressions that form a structure on the metal membrane. The membrane can be essentially designed similarly to a "loudspeaker" and have corresponding ridges and waves.

[0022] In further embodiments, the membrane can be designed as a geometrically shaped disc and referred to as such, wherein the geometric shape also includes the structures mentioned above.

[0023] In further embodiments not covered by the present invention, the compressor chamber and / or the media chamber could substantially have the shape of a spherical segment and the membrane could form the base area of ​​the spherical segment. The corresponding inner walls of the compressor chamber and the media chamber are substantially concave and thus have a curved inner side. The structured membrane can then, for example, rest against the curved inner walls, wherein after complete deformation of the membrane on the corresponding inner wall either centrally circumferential grooves can be created or the membrane can be deformed to such an extent that it is in surface contact with the corresponding inner wall. The compressed gas or gas mixture can then be pressed into at least one channel in the housing, which is connected to the second connection.

[0024] In yet further embodiments not covered by the present invention, the substantially concavely shaped inner walls of the compression chamber and the media chamber could have grooves or the like extending towards the center, the depth and width of which can increase or decrease, so that during gradual compression by deformation of the membrane, the compressed gas or gas mixture is pressed into the grooves or the like and discharged from there after complete deformation of the membrane, thereby taking into account the fact that the membrane rests against the inner wall of the compression chamber in the fully deformed state. This also applies accordingly to the introduction of the incompressible medium when the membrane rests against the inner wall of the media chamber.

[0025] According to the invention, the compressor chamber and / or the media chamber are essentially designed in the shape of a stepped pyramid or cone, and the membrane of the compressor chamber and / or the media chamber has corresponding steps. This can result in a stepwise deformation of the membrane, whereby during the deformation process upon compression of the gas or gas mixture, the steps of the membrane come into contact with the corresponding steps of the media chamber or compressor chamber.

[0026] The membrane can be deformable to such an extent that it comes from an initial position into contact with the inner wall of the compressor chamber and / or the media chamber.

[0027] In further embodiments, the housing of the high-pressure compressor can be constructed in layers and have at least a first compressor head with the compressor chamber and a second compressor head with the media chamber, wherein the membrane is arranged between the first compressor head and the second compressor head.

[0028] The layered structure provides a simple design for the high-pressure compressor. Furthermore, the assembly of the high-pressure compressor is straightforward. For example, the individual layers can be secured together with screws or similar fasteners, with the screws or similar fasteners passing through holes in the respective layers. Furthermore, the layered structure offers the possibility of clamping the diaphragm between the individual layers and making the interior of the housing completely gas-tight using additional sealing elements.

[0029] In general, the deformability of the diaphragm has the advantage that a greater deflection can be achieved compared to simple, disc-like diaphragms. This means that a significantly higher compression of a gas or gas mixture can be achieved in a small installation space, particularly compared to disc-like, non-deformable diaphragms. The greater deflection of the diaphragm also makes it possible to reduce the frequency of the diaphragm, i.e. the movements of the diaphragm in the directions required for compression, whereby the performance in relation to the amount of compressed gas or gas mixture provided is at least as great as with a comparable, non-deformable diaphragm. Lower frequencies have a particularly positive effect on the service life of the diaphragm and thus of the high-pressure compressor. The deformability of the diaphragm can be achieved in particular through the structured design, as stated above in various embodiments.

[0030] The above-mentioned object is also achieved by a compressor system for high-pressure compression of a gas or gas mixture, comprising at least one high-pressure compressor according to one of the above-mentioned embodiments, a gas or gas mixture supply, a gas or gas mixture storage, a medium supply and conveying means for conveying a gas or gas mixture and an incompressible medium and control means for regulating the flow of the gas or gas mixture and the incompressible medium via associated lines, wherein the high-pressure compressor has a housing that surrounds a compressor chamber and a media chamber, wherein the compressor chamber and the media chamber are separated from each other in the housing by a membrane, the high-pressure compressor has at least one first connection opening into a media chamber, the first connection being connected to the media supply via associated lines and corresponding conveying and / or control means, so that an incompressible medium can be introduced from the media supply via the first connection into the media chamber and from the media chamber into the media supply, the high-pressure compressor has at least one second connection opening into the compressor chamber, the at least one second connection being connected to the gas or gas mixture supply and the gas or gas mixture storage via associated lines and corresponding conveying and / or control means,so that a gas or gas mixture can be introduced from the gas or gas mixture supply into the compressor chamber and from the compressor chamber into the gas or gas mixture storage, and the incompressible medium can be pressurised via associated conveying and / or control means, so that a deformation of the membrane and thereby a compression of the gas or gas mixture contained in the compressor chamber can be achieved, for which purpose lines to and from the gas or gas mixture supply, the gas or gas mixture storage and the media supply can be closed off via corresponding control means.

[0031] In an advantageous embodiment of the compressor system, the pressurization of the medium within the at least one media chamber can be carried out via the conveying means, which convey the less compressible medium into the at least one media chamber. The conveying means are designed, for example, as a piston and / or a pump. It is particularly advantageous if one conveying means is designed as a pump, so that the piston can be completely omitted. With such an advantageous embodiment, a system without a piston can be used as the conveying and / or pressurizing means.

[0032] In a further advantageous embodiment, the media circuit and the medium conveyed and conveyed through it can be heated and / or air-conditioned at least in the region of the at least one first connection. This advantageously achieves a viscosity of the incompressible medium such that no counterpressure is generated on the conveying means when flowing into the at least one media chamber via the at least one first connection.

[0033] The system offers the possibility of high-pressure compression of a gas or gas mixture with at least one high-pressure compressor. Due to the large displacement of the diaphragm, this compressor requires fewer load cycles to compress the same amount of gas compared to a conventional compressor. The delivery and control systems also have reduced delivery and control cycles. This allows for a simpler system design. It also simplifies system control.

[0034] Further advantages, features and design options emerge from the following description of figures of non-limiting embodiments. Brief description of the drawings

[0036] Elements provided with the same reference numerals in the drawings essentially correspond to one another unless otherwise stated. Furthermore, components that are not essential to understanding the technical teaching disclosed herein are omitted. Reference numerals will not be repeated for all elements already introduced and illustrated, provided that the elements themselves and their function have already been described or are known to a person skilled in the art. Detailed description of implementation examples

[0037] The figures show an exemplary embodiment of a high-pressure compressor 100, a compressor system 500, and a method for high-pressure compression in a compressor system 500, which are described below by way of example. These are possible embodiments of the technical teaching disclosed herein. The embodiments shown and described below are therefore not limiting and may additionally include features or alternatives specified herein.

[0038] Fig. 1 shows an exploded view of a high-pressure compressor 100. The high-pressure compressor 100 can be used, for example, to compress a gas, such as hydrogen, or a gas mixture. This involves high-pressure compression of the gas. In this context, high-pressure compression refers to pressures of approximately 40 bar and above.

[0039] Conventional high-pressure compressors feature a sliding piston to generate the high pressures. The piston is moved a relatively large distance within a cylindrical tube to achieve the high compression of the gas.

[0040] The high-pressure compressor 100 described herein has the advantage over known high-pressure compressors in that the device is relatively small and, moreover, no moving components are provided that are in contact with the environment. This ensures a gas-tight design. Furthermore, there is no abrasion and thus no destruction of sealing means as in the prior art because optionally provided seals are not moved, and in other designs, seals can be omitted. The component intended for compressing a gas, in the form of a membrane 200 made of metal or a metal alloy, is arranged within a housing 120 of the high-pressure compressor 100 and is therefore not in contact with the environment.

[0041] The high-pressure compressor 100 from Fig. 1has a housing 120 having a first compressor head 300 and a second compressor head 400. In the illustrated embodiment, the compressor heads 300 and 400 are identically constructed, so that descriptions of one of the compressor heads 300, 400 also apply to the other compressor head 300, 400. In further embodiments not shown, however, the compressor heads 300, 400 may also differ from one another, particularly in the design and arrangement of connections, etc.

[0042] The compressor heads 300, 400 are made of metal or a metal alloy and each have a solid plate 310, 410. The design of the compressor heads 300, 400 is in Fig. 2 shown.

[0043] The material used for the compressor heads 300, 400 can be, for example, stainless steel or a stainless steel alloy, such as a stainless steel alloy of group 316 L.

[0044] The compressor heads 300, 400 each have a compressor chamber 330 and a media chamber 430 on the opposite sides when assembled. The compressor chamber 330 serves to accommodate a gas or gas mixture that is compressed. The media chamber 430 serves to accommodate a medium required for the deformation of the diaphragm 200 to compress the gas or gas mixture.

[0045] Here, the compressor chamber 330 and the media chamber 430 primarily serve to introduce the gas / gas mixture or the medium into the chambers. During high-pressure compression, the diaphragm 200 is displaced in such a way that it comes into contact with the opposing inner walls of the compressor chamber 330 and the media chamber 430. Thus, a gas / gas mixture or a medium can also be accommodated in the space spanned by the compressor chamber 330 or the media chamber 430 within the compressor heads 300, 400 through a corresponding deformation of the diaphragm 200.

[0046] In the illustrated embodiment, the compressor chamber 330 and the media chamber 430 are configured to have steps 332, 432. The steps 332, 432 allow the membrane 200 to substantially fully contact the inner walls of the compressor chamber 330 and the media chamber 430.

[0047] The membrane 200, which is made of a metal or a metal alloy, is arranged between the compressor heads 300, 400. Particularly suitable materials are precious metals or precious metal alloys, preferably a stainless steel alloy of group 316 L. The membrane 200 is structured. The structuring of the membrane 200 enables the deformation of the membrane 200 such that it can come into contact with both the inner wall of the compressor chamber 330 and the inner wall of the media chamber 430. For this purpose, the membrane 200 has beads 210, as shown in Fig. 8 shown schematically.

[0048] During high-pressure compression, the membrane 200 can be deformed due to the beads 210 so that it gradually comes into contact with the stepped inner walls of the compression chamber 330 and the media chamber 430.

[0049] The design of the membrane 200 therefore makes it possible to use the entire volume within the housing 120 of the high-pressure compressor 100, consisting of the compressor chamber 330 and the media chamber 430, for the compression of a gas / gas mixture.

[0050] This allows for an adjustment of the compression ratio of gases or gas mixtures, depending on the design of the high-pressure compressor 100 and its components. In particular, the deformability of the diaphragm 200 is crucial for compression. The greater the deformability, the greater the compression. For this purpose, the diaphragm 200 can have a variety of structures required for deformation. In contrast to simple metal diaphragms, which can only be deflected slightly in one direction, for which purpose they are concave or convex ("bowl-like") in every initial position - depending on the definition - the diaphragm 200 can also assume a neutral position ( Fig. 8) and deformed from the neutral position in both directions. The structures in the diaphragm 200 and the beads 210 also allow the diaphragm 200 to maintain the deformed positions without any further force being applied.

[0051] To deform the membrane 200 for the high-pressure compression of a gas / gas mixture introduced via the compression chamber 330, an incompressible medium is introduced under pressure via the media chamber 430. This ensures that the pressure exerted by the medium on the membrane 200 exerts a correspondingly high pressure on the gas / gas mixture, which is then compressed. For example, water or (hydraulic) oil can be used as the incompressible medium.

[0052] Both the compressor chamber 330 and the media chamber 430 each have at least one connection 320, 420 through which the gas / gas mixture or the medium is supplied and discharged. In further embodiments, separate connections can be provided for supplying and discharging the gas / gas mixture or the medium.

[0053] The supply and discharge take place centrally in the central area of ​​the compressor chamber 330 or the media chamber 430. In particular, the second connection 320 for supplying gas / a gas mixture can be designed such that, starting from a central supply opening in the second connection 320 on the outside of the compressor head 300, the connection 320 merges into a plurality of smaller channels that have a smaller diameter compared to the inlet diameter. These channels then protrude into the compressor chamber 330 via corresponding openings. This prevents a localized, central load on the membrane 200 during the inflow / outflow of the gas / gas mixture or the medium. By dividing the central inlet into many smaller channels, the load is distributed. These openings in the compressor chamber 330 and in the media chamber 430 can extend over an area that corresponds, for example, to three times the diameter of the connection 320, 420.Preferably, the openings of these channels can only open into the area which has the greatest depth in relation to the volume of the compressor chamber 330 or the media chamber 430.

[0054] The supply and discharge of gas / gas mixture and the medium is controlled via appropriate valves.

[0055] The diaphragm 200 itself is arranged between the opposing flat surfaces of the cylinder heads 300, 400 and the plates 310, 410. The diaphragm 200 has a planar extension that is larger than the planar extension of the compressor chamber 330 and the media chamber 430. Thus, the diaphragm 200 rests against the plates 310, 410 in the installed state.

[0056] The two cylinder heads 300, 400 and the diaphragm 200 arranged therebetween are connected to one another via fastening means 110. The plates 310, 410 have through-openings 314, 414 through which threaded rods 112 are guided. The cylinder heads 300, 400 and the diaphragm 200 can be connected to one another and the diaphragm 200 can be clamped using nuts 114 and washers 116. This seals the compressor chamber 330 and the media chamber 430 from the environment. At least one sealing ring can additionally be arranged in the area of ​​the contact surfaces between the compressor heads 300, 400 and the diaphragm 200. Furthermore, structures can also be provided in the contact surfaces of the compressor heads 300, 400, which partially deform the diaphragm 200 when connected. Furthermore, the membrane 200 may also have structures required for this purpose, in addition to the structures required for the deformation.

[0057] Fig. 2shows different views of a first and second compressor head of the high pressure compressor of Fig. 1 Walls 312, 412 are located between the openings 314, 414. The design of the compressor heads 300, 400 is selected such that they have a sufficiently thick wall around the compressor chamber 330 and the media chamber 430. The wall thickness is to be determined with regard to the internal pressure during high-pressure compression.

[0058] Fig. 3 shows a schematic representation of a compressor system 500 with a high pressure compressor 100 according to the embodiment of Fig. 1 .

[0059] In further embodiments not shown, a compressor system 500 can also be provided with a modification of the Fig. 1The compressor system 500 can be operated with the high-pressure compressor 100 shown, which falls under the technical teaching described herein. Finally, a compressor system 500 can in principle also comprise several high-pressure compressors 100, which are connected, for example, in parallel or in series.

[0060] In addition to the high-pressure compressor 100, the compressor system 500 includes lines and control devices, as well as valves, a piston 510, and a tank 514 containing an incompressible medium. The tank 514, the piston 510, and a pump 512 are part of a media circuit, which in turn is part of the compressor system 500.

[0061] The compressor system 500 has a gas or gas mixture circuit which, in addition to the lines for the supply and discharge of the gas or gas mixture, has control devices, valves, a reservoir 520 in which the gas or gas mixture is stored for the high-pressure compression, and a connection to any application 530.

[0062] The compressor system 500 also includes pressure relief valves that allow gas to escape into the atmosphere if critical, adjustable pressures in the system are exceeded. In the illustrated embodiment of the compressor system 500, a gas or gas mixture is compressed from a pressure of at least 10 bar in the reservoir 520 to approximately 1200 bar, so that a gas or gas mixture with a pressure of approximately 1200 bar is provided to the application 530.

[0063] The compression process in the compressor system 500 via the high pressure compressor 100 is shown in the Fig. 4-7 shown and is described below with reference to the Fig. 4-7 described. Filling the high-pressure compressor 100 (Fig. 4)

[0064] The gas side or compressor chamber 330 of compressor head 300 is filled with gas from reservoir 520. For this purpose, the valve of reservoir 520 and a valve 522 are opened, allowing gas to be supplied to compressor chamber 330 via second connection 320. Gas is stored in reservoir 520 at a pressure of at least 10 bar. Membrane 200 is deflected toward the water side, i.e., toward media chamber 430, and pump 512 in the media circuit pumps the medium (water) back into tank 514, which serves as a water reservoir, for this step.

[0065] A relief line of the media circuit from the cylinder of the piston 510 is opened and due to the higher pressure on the gas side (compressor chamber side), the membrane 200 is completely applied to the inner wall of the media chamber 430 of the compressor head 400 and the head of the piston 510 is moved to its starting position. Hub into the application (Fig. 5)

[0066] The inlet valve 522 on the gas side is closed, and the valve 526 for application 530 is opened. At the same time, the circuit in the media circuit back to tank 514 and the relief line are closed, and the water is forced into the rear side of the cylinder of piston 510, whereby more volume is pumped via the water side of the high-pressure compressor 100 into the compressor head 400. This volume change ensures a compression of the gas on the gas side and thus a pressure increase in application 530. Step 1 to relieve pressure on the high-pressure compressor 100 (Fig. 6)

[0067] The valve 526 for the gas application 530 is closed. The water circuit in the media circuit back to the tank 514 is opened, and in parallel, the relief line into the tank 514 is opened. Due to the pressure applied on the gas side of the high-pressure compressor 100, the head of the piston 510 is pushed back a little to its original position depending on the prevailing pressure, and the escaping water is collected in the tank 514. Step 2 to relieve pressure on the high-pressure compressor 100 (Fig. 7)

[0068] The relief line to tank 514 remains open, and pump 512 continues to pump back into tank 514. The valve 524 for pressure relief on the gas side is opened, and due to the small volumes, the pressure can be reduced quite quickly, or the diaphragm 200 can be deflected further toward the water side.

[0069] The valve 522 can then be opened again and the valve 524 can be closed to relieve pressure in order to supply gas again into the compression chamber 330 of the cylinder head 300 and to perform high-pressure compression.

[0070] In Fig. 8 Schematic representations of an exemplary embodiment of a diaphragm 200 for a high-pressure compressor 100 are shown. The diaphragm 200 is designed as a metal diaphragm and has structural elements that enable deformation. These are structures of the diaphragm 200 that enable deformation such that the diaphragm 200 comes into contact with both the inner wall of the compressor chamber 330 and the inner wall of the media chamber 430, and can also assume a neutral position.

[0071] This can be achieved by structuring with beads 210, as shown in the figures. However, it is additionally or alternatively possible to modify the internal structure of the membrane 200 by introducing additional materials or by weakening areas that are crucial for fulfilling the required properties, instead of geometrically shaping the membrane 200 to achieve the required deformability.

[0072] In one embodiment of the compressor system, the valve 522 and the valve 524 and the valve 526 may be designed as a check valve.

[0073] Fig. 9 shows a schematic diagram of high pressure compression in a compressor system 500 having a high pressure compressor 100.

[0074] In a first step S1, the high-pressure compressor 100 is filled from the reservoir 520 (see Fig. 4 ). For this purpose, the corresponding valves are opened or closed.

[0075] In step S2, the stroke takes place in the application 530 (see Fig. 5 ) from the high-pressure compressor 100.

[0076] In step S3, a first intermediate step is carried out to relieve the pressure of the high-pressure compressor 100 (see Fig. 6 ), whereby the supply of gas from the high-pressure compressor 100 to the gas application 530 is closed.

[0077] In step S4, a second intermediate step is carried out to relieve the pressure of the high-pressure compressor 100 (see Fig. 7 ), whereby pressure relief on the gas side occurs by opening the valve 524 and reducing the pressure.

[0078] In step S5, a switchover occurs for a new filling of the high-pressure compressor 100, for which the valve 522 is opened again and the valve 524 is closed for pressure relief.

[0079] The above process can be repeated over and over to achieve continuous high pressure compression for various applications.

[0080] Advantageously, the entire internal space in the housing 120 of the high-pressure compressor 100 is used for compression. Furthermore, only the membrane 200 is moved or deformed within the housing 120, so that, on the one hand, the space required for compression is not dependent on the compression process via moving components, and, furthermore, a substantially complete sealing of the compression chamber from the environment is achieved.
