Description

The present invention broadly relates to the technical field of gas compression devices, the field of compressed gas energy storage technology and the technical field of compressed gas energy conversion devices.

In general, the following is expressly stated before the further explanations: If the term "gas" is used in the text of the present description of the invention and the patent claims, this term currently primarily means the gas "air" for purely practical economic reasons, however the present invention is by no means limited to the use of air as the gas used from a purely physical and technical point of view. Rather, from a purely physical and technical point of view, any gas, for example so-called “biogas”, can be used for the implementation of the invention described below. The use of the term "gas" in the text of the present description of the invention and the patent claims is by no means to be understood as being restricted solely to the gas air, although at least at present the use of the gas air is by far the predominant preference over the physical the use of other gases, such as any hydrocarbon gases, which is technically possible without further ado - and under certain conditions also makes very good economic sense.

Gas compressed above atmospheric pressure and in particular air compressed above atmospheric pressure, which is often simply referred to as "compressed air", has had great importance and a wide variety of practical applications in industrial technology for well over a hundred years. Compressed air has also been used as an energy store and as a means of propulsion for well over a hundred years, for example in compressed air-driven locomotives on mine railways. With the currently advancing so-called "energy transition" and the associated ever-widening spread of wind turbines and solar energy systems, the electrical energy production of which is naturally subject to very strong fluctuations over time, the need for such energy storage devices is increasing, with the help of which wind turbines and solar energy systems can temporarily be used in excess store energy provided and not immediately usable by electrical energy end consumers and retrieve it later when required, ie when the wind turbines and solar energy systems just don't provide enough electrical energy to cover the electrical energy consumption via the power grid. There are various types of such energy storage devices in the prior art, including those in which the energy is stored in the form of compressed air, which is filled into compressed air cylinders or compressed air tanks by means of an air compressor. To put it very simply, this compressed air, which can be stored and stored in this way for basically any length of time, can then be released again later at any time and can be used as a drive means for driving an electric energy generator. Devices of this type, referred to as “compressed air energy storage systems”, are already, for example, in DE 10 2013 105 186 A1 , in the DE 10 2015 222 983 A1 , in which - not previously published - DE 10 2019 002 370 A1 or in the U.S. 2012/0210705 A1 described. Gas compressor devices that are technically related to this in a certain way are described in AT 10 225 E, of DE 43 28 264 A1 , the US 3,942,323A and the EP 0 193 498 A2 .

For compressing air or more generally for compressing gas, conventional electrically driven solid mechanical screw compressors and conventional electrically driven solid mechanical piston compressors have been known for many decades and are in use by the millions worldwide. Also found in the prior art are different and somewhat unconventional hydraulic air compression devices with double-acting cylinders in which a piston slides back and forth and one cylinder chamber is filled with air while the other cylinder chamber is filled with high pressure by means of an electrically powered pump oil is being pumped. As soon as the oil pressure in one cylinder chamber is higher than the pressure of the air in the chamber opposite the cylinder chamber just mentioned, this air is compressed and, for example, filled into compressed air storage bottles provided for it. Such a hydraulic air compression device just mentioned is for example in DE 10 2013 105 186 A1 described as part of the compressed air energy storage system presented in this publication. This latter, from the DE 10 2013 105 186 A1 Although the known hydraulic air compression device preferably runs only very slowly, the heat generated during air compression, which actually represents a loss of efficiency as such, can be collected very well and stored, for example, in the form of heated water. However, for the operation of in the DE 10 2013 105 186 A1 described hydraulic air compression device is still a conventional electrically powered solid state mechanical air compressor, such as an electrically powered solid state mechanical screw compressor or an electrically powered solid-mechanical piston compressor, useful as a pre-filler and for really efficient operation of the DE 10 2013 105 186 A1 described hydraulic air compression device even absolutely necessary.

In general and completely independently of the above-described possible uses of conventional electrically driven solid-state mechanical screw compressors and conventional electrically driven solid-state mechanical piston compressors, these two types of conventional compressors just mentioned have the following operational restrictions: A conventional electrically driven solid-state mechanical screw compressor must and should run as long as possible for optimal operation be switched off and on again as little as possible. On the other hand, a conventional electrically driven solid-state mechanical piston compressor should not be expected to operate for significantly more than fifteen minutes without a cooling break.

Such operational restrictions are subject to the DE 10 2013 105 186 A1 Described hydraulic air compression device not, ie they can tolerate both readily continuous operation as well as an operating mode in which they are repeatedly switched on and off again within very short time intervals, but works in the DE 10 2013 105 186 A1 The hydraulic air compression device described preferably only very slowly, which on the one hand is definitely an advantage for heat storage, as already indicated above, but on the other hand, with regard to some time-critical applications, for example with regard to the frequently also time-critical application in an air pressure energy storage system for the power grid - Buffer storage of energy from solar energy systems and wind turbines, can be disadvantageous.

The conversion of the energy stored in the form of compressed air into electrical energy is with the in the DE 10 2013 105 186 A1 Compressed air energy storage system described in principle readily possible, but has in the DE 10 2013 105 186 A1 compressed air energy storage system described a serious disadvantage. It is in this compressed air energy storage system - seen in relation to the workability of the compressed air used therein - too much solid material required for the piston. The piston is therefore too heavy, the ratio of the piston mass to the working capacity of the compressed air is too poor and the operation of the entire system is therefore too sluggish.

In the - not previously published - DE 10 2019 002 370 A1 are already several compared to the one in the DE 10 2013 105 186 A1 Compressed air energy storage system described described significantly improved and expanded compressed gas energy conversion devices, including in particular a compressed gas energy conversion heat exchanger device and a compressed gas energy conversion heat exchanger device precursor device.

• Als Beispiel einer Startposition wird die in den 1 bis 4 gezeigte Position der Kolbenstange 14 angenommen, bei welcher sich der erste Kolben 15 ungefähr in der Mitte des ersten Hohlzylinders 2, der zweite Kolben 16 ungefähr in der Mitte des zweiten Hohlzylinders 5, der dritte Kolben 17 ungefähr in der Mitte des dritten Hohlzylinders 8 und der vierte Kolben 18 ungefähr in der Mitte des vierten Hohlzylinders 11 befinden. Die vierte Kammer 22 und die fünfte Kammer 23 sind jeweils voller Öl. In der ersten Kammer 19, der zweiten Kammer 20, der dritten Kammer 21, der sechsten Kammer 24, der siebenten Kammer 25 und der achten Kammer 26 befindet sich Luft auf Atmosphärendruck.

The first exemplary embodiment of the hydraulic piston device 1 functions in its operating mode as the first air compression device 1, for example, as follows:

• As an example of a starting position in the 1 until 4 The position of the piston rod 14 shown is assumed, in which the first piston 15 is approximately in the center of the first hollow cylinder 2, the second piston 16 approximately in the center of the second hollow cylinder 5, the third piston 17 approximately in the center of the third hollow cylinder 8 and the fourth piston 18 are approximately in the middle of the fourth hollow cylinder 11. The fourth chamber 22 and the fifth chamber 23 are each full of oil. In the first chamber 19, the second chamber 20, the third chamber 21, the sixth chamber 24, the seventh chamber 25 and the eighth chamber 26 there is air at atmospheric pressure.

The valve device belonging to the first liquid connection device 27 is closed. The valve device belonging to the second liquid connection device 28 is open. The valve device belonging to the third fluid connection device 29 is open. The valve device belonging to the fourth liquid connection device 30 is closed. The valve device belonging to the first gas connection device 31 is open. The valve device belonging to the second gas connection device 32 is closed. The valve device belonging to the third gas connection device 33 is open. The valve device belonging to the fourth gas connection device 34 is closed. The valve device belonging to the fifth gas connection device 35 is closed. The valve device belonging to the sixth gas connection device 38 is closed. The valve device belonging to the seventh gas connection device 39 is open. The valve device belonging to the eighth gas connection device 40 is closed. The valve device belonging to the ninth gas connection device 41 is open. The valve device belonging to the tenth gas connection device 42 is open. The valve device belonging to the eleventh gas connection device 45 is closed. The valve device belonging to the twelfth gas connection device 46 is open.

Further oil is then pumped from the oil tank via the third liquid connection device 29 into the fifth chamber 23 by means of a pump. Due to the incompressibility of the oil, this means that, starting from the in the 1 until 4 assumed starting position shown, the piston rod 14 moves with the first piston 15, the second piston 16, the third piston 17 and the fourth piston 18 to the right. Accordingly, at the same time, the oil is conveyed out of the fourth chamber 22 via the second fluid connection device 28 into the oil tank. The air in the sixth chamber 24 is pressed out of the sixth chamber 24 via the twelfth gas connection device 46 and fed to the compressed air storage device. The air from the second chamber 20 and the air from the eighth chamber 26 via the third gas line 43 and the fourth Gas line 44 is pressed through the tenth gas connection device 42 into the third chamber 21 and forms an excess air pressure there. The latter happens even when the volume of the third chamber 21 increases because two chambers—namely the second chamber 20 and the eighth chamber 26—act in only one—namely the third chamber 21. The excess air pressure in the third chamber 21 accordingly helps to force the air out of the sixth chamber 24 through the twelfth gas connection device 46 and also to force the oil out of the fourth chamber 22 through the second liquid connection device 28 . The piston stroke of the piston rod 14 is coordinated such that the movement of the piston rod 14 in the image of 1 until 4 to the right lasts until both the second chamber 20 and the fourth chamber 22 as well as the sixth chamber 24 and the eighth chamber 26 each have a volume of almost zero. Meanwhile, the first chamber 19 has sucked in air via the first gas connection device 31 and the seventh chamber 25 has sucked in air via the third gas connection device 33 . Accordingly, at the end of the movement of the piston rod 14 have in the picture 1 until 4 to the right both the first chamber 19 and the third chamber 21 and the fifth chamber 23 and the seventh chamber 25 assumed their maximum possible volume. In this case, air is then at atmospheric pressure both in the first chamber 19 and in the seventh chamber 25 . The third chamber 21 contains air at a pressure above atmospheric pressure, ie compressed air, and the fifth chamber 23 contains oil.

After completion of the stroke of the piston rod 14 in the image of 1 until 4 The valve devices are switched to the right as follows: The valve device belonging to the first liquid connection device 27 is opened. The valve device belonging to the second liquid connection device 28 is closed. The valve device belonging to the third liquid connection device 29 is closed. The valve device belonging to the fourth liquid connection device 30 is opened. The valve device belonging to the first gas connection device 31 is closed. The valve device belonging to the second gas connection device 32 is opened. The valve device belonging to the third gas connection device 33 is closed. The valve device belonging to the fourth gas connection device 34 is opened. The valve device belonging to the fifth gas connection device 35 is opened. The valve device belonging to the sixth gas connection device 38 is opened. The valve device belonging to the seventh gas connection device 39 is closed. The valve device belonging to the eighth gas connection device 40 is opened. The valve device belonging to the ninth gas connection device 41 is closed. The valve device belonging to the tenth gas connection device 42 is closed. The valve device belonging to the eleventh gas connection device 45 is opened and the compressed air located in the third chamber 21 is fed to the compressed air storage device. The valve device belonging to the twelfth gas connection device 46 is closed.

Oil is now pumped from the oil tank via the first liquid connection device 27 into the fourth chamber 22 by means of the pump. Due to the incompressibility of the oil, this leads to the fact that the 1 until 4 the piston rod 14 with the first piston 15, the second piston 16, the third piston 17 and the fourth piston 18 is now moved to the left. Accordingly, at the same time, the oil is conveyed out of the fifth chamber 23 via the fourth liquid connection device 30 into the oil tank. The air located in the third chamber 21 is pressed out of the third chamber 21 via the eleventh gas connection device 45 and fed to the compressed air storage device. The air from the first chamber 19 and the air from the seventh chamber 25 is pressed via the first gas line 36 or via the second gas line 37 through the fifth gas connection device 35 into the sixth chamber 24 and forms an excess air pressure there. The latter happens even when the volume of the sixth chamber 24 increases because two chambers—namely the first chamber 19 and the seventh chamber 25—act in only one—namely the sixth chamber 24. The excess air pressure in the sixth chamber 24 accordingly helps to press the air out of the third chamber 21 through the eleventh gas connection device 45 and also to press out the oil from the fifth chamber 23 through the fourth liquid connection device 30 . The piston stroke of the piston rod 14 is coordinated such that the movement of the piston rod 14 in the image of 1 until 4 to the left lasts until both the first chamber 19 and the third chamber 21 as well as the fifth chamber 23 and the seventh chamber 25 each have a volume of almost zero. Meanwhile, the second chamber 20 has sucked in air via the sixth gas connection device 38 and the eighth chamber 26 has sucked in air via the eighth gas connection device 40 . Accordingly, at the end of the movement of the piston rod 14 have in the picture 1 until 4 to the left both the second chamber 20 and the fourth chamber 22 and the sixth chamber 24 and the eighth Chamber 26 assumed its maximum volume. In this case, air is then at atmospheric pressure both in the second chamber 20 and in the eighth chamber 26 . The sixth chamber 24 contains air at a pressure above atmospheric pressure, ie compressed air, and the fourth chamber 22 contains oil.

After completion of the stroke of the piston rod 14 in the image of 1 until 4 to the left, the valve devices are switched back to their first position described above, namely: The valve device belonging to the first liquid connection device 27 is opened. The valve device belonging to the second liquid connection device 28 is closed. The valve device belonging to the third liquid connection device 29 is closed. The valve device belonging to the fourth liquid connection device 30 is opened. The valve device belonging to the first gas connection device 31 is closed. The valve device belonging to the second gas connection device 32 is opened. The valve device belonging to the third gas connection device 33 is closed. The valve device belonging to the fourth gas connection device 34 is opened. The valve device belonging to the fifth gas connection device 35 is opened. The valve device belonging to the sixth gas connection device 38 is opened. The valve device belonging to the seventh gas connection device 39 is closed. The valve device belonging to the eighth gas connection device 40 is opened. The valve device belonging to the ninth gas connection device 41 is closed. The valve device belonging to the tenth gas connection device 42 is closed. The valve device belonging to the eleventh gas connection device 45 is opened. The valve device belonging to the twelfth gas connection device 46 is closed.

Oil is now pumped from the oil tank via the third liquid connection device 29 into the fifth chamber 23 by means of the pump. Due to the incompressibility of the oil, this leads to the fact that the 1 until 4 the piston rod 14 with the first piston 15, the second piston 16, the third piston 17 and the fourth piston 18 is now moved to the right again. Accordingly, at the same time, the oil is conveyed out of the fourth chamber 22 via the second fluid connection device 28 into the oil tank. The air in the sixth chamber 24 is pressed out of the sixth chamber 24 via the twelfth gas connection device 46 and fed to the compressed air storage device. The air from the second chamber 20 and the air from the eighth chamber 26 is pressed via the third gas line 43 or via the fourth gas line 44 through the tenth gas connection device 42 into the third chamber 21 and forms an excess air pressure there. The latter happens even when the volume of the third chamber 21 increases because two chambers—namely the second chamber 20 and the eighth chamber 26—act in only one—namely the third chamber 21. The excess air pressure in the third chamber 21 accordingly helps to force the air out of the sixth chamber 24 through the twelfth gas connection device 46 and also to force the oil out of the fourth chamber 22 through the second liquid connection device 28 . The piston stroke of the piston rod 14 is coordinated such that the movement of the piston rod 14 in the image of 1 until 4 to the right lasts until both the second chamber 20 and the fourth chamber 22 as well as the sixth chamber 24 and the eighth chamber 26 each have a volume of almost zero. Meanwhile, the first chamber 19 has sucked in air via the first gas connection device 31 and the seventh chamber 25 has sucked in air via the third gas connection device 33 . Accordingly, at the end of the movement of the piston rod 14 have in the picture 1 until 4 to the right both the first chamber 19 and the third chamber 21 and the fifth chamber 23 and the seventh chamber 25 assumed their maximum possible volume. In this case, air is then at atmospheric pressure both in the first chamber 19 and in the seventh chamber 25 . The third chamber 21 contains air at a pressure above atmospheric pressure, ie compressed air, and the fifth chamber 23 contains oil.

After completion of the stroke of the piston rod 14 just described in the picture 1 until 4 to the right, the valve devices are then switched over in preparation for the repeated stroke of the piston rod 14 to the left, as has already been explained above before the description of the stroke of the piston rod 14 to the left. The piston rod 14 then moves back and forth with the first piston 15, the second piston 16, the third piston 17 and the fourth piston 18, and compressed air is alternately provided at the eleventh gas connection device 45 or at the twelfth gas connection device 46 which either - as described above - can be supplied to a compressed air storage device, but which can also instead be supplied to any consumer of compressed air, for example a blower device or a compressed air hammer device. In other exemplary embodiments, the hydraulic piston device 1 can also be provided, the eleventh Gas connection device 45 and the twelfth gas connection device 46 are to be provided with such valve devices that a user can optionally decide operatively whether the compressed air just emerging from the respective eleventh or twelfth gas connection device 45, 46 is either introduced into a compressed air storage device or supplied to a consumer of compressed air .

6 shows schematically and not to scale a second embodiment of the hydraulic piston device 1 known as such from the prior art. This second embodiment of the hydraulic piston device 1 functions in principle in exactly the same way as the one above with reference to 1 until 4 described first embodiment of the hydraulic piston device 1, but differs from this by the arrangement and the proportions of the four hollow cylinders 2, 5, 8, 11, which results in improved operational properties.

In the case of the above with reference to the 1 until 4 All four hollow cylinders 2, 5, 8, 11 described in the first exemplary embodiment of the hydraulic piston device 1 have the same shape and size, and each one of the four hollow cylinders 2, 5, 8, 11 is arranged separately from the others, so that there are three spatial There are sections in which the piston rod 14 is located outside of any hollow cylinder 2, 5, 8, 11 (see in this respect 1 until 4 ). Such a design of the hydraulic piston device 1 is quite possible as an exemplary embodiment, it actually works and is well suited for explaining the basic functioning of the hydraulic piston device 1, but such a design is far from optimal for the purposes of gas compression or air compression.

At the in 6 shown second embodiment of the hydraulic piston device 1, all four hollow cylinders 2, 5, 8, 11 each have the same length. The second hollow cylinder 5 and the third hollow cylinder 8 each have the same diameter. The first hollow cylinder 2 and the fourth hollow cylinder 11 each have the same diameter, and the diameter of the first hollow cylinder 2 is larger than the diameter of the second hollow cylinder 5. It is particularly preferred to make the diameter of the first hollow cylinder 2 at least twice as large as the diameter of the second hollow cylinder 5. The size of the first piston 15 and the size of the fourth piston 18 must of course also be adjusted accordingly in order to ensure that they continue to fit closely to the inner wall of the first hollow cylinder 2 and the fourth hollow cylinder 11 snuggly and continue to ensure a pneumatically tight separation of the first chamber 19 from the second chamber 20 and the seventh chamber 25 from the eighth chamber 26. The advantage of such in 6 shown construction compared to in the 1 until 4 The construction shown for generating compressed air is that in the second exemplary embodiment of the piston device 1, when the piston rod 14 moves to the right, the second chamber 20 with a large volume and the eighth chamber 26 with a large volume flow into the third chamber 21, which has a much smaller volume , act in such a way that a significantly higher excess air pressure can be achieved in the third chamber 21 than in the first embodiment of the piston device 1. The same also applies to the movement of the piston rod 14 to the left: In the second embodiment of the piston device 1 act during movement of the piston rod 14 to the left, the first chamber 19 with a large volume and the seventh chamber 25 with a large volume into the sixth chamber 24, which has a much smaller volume, so that a significantly higher excess air pressure is achieved in the sixth chamber 24 can than in the first exemplary embodiment of the piston device 1 .

Generally speaking, the size ratios of the four hollow cylinders 2, 5, 8, 11 to one another are always in relation to the gas pressure or air pressure that can be achieved at the end of the gas or air compression.

This in 6 The second exemplary embodiment of the hydraulic piston device 1 shown is also set up such that the first hollow cylinder 2 and the second hollow cylinder 5 are seated directly against one another, so that the second end wall 4 and the third end wall 6 coincide at least partially. In addition, the third hollow cylinder 8 and the fourth hollow cylinder 11 sit directly against one another, so that the sixth end wall 10 and the seventh end wall 12 coincide at least partially. Such a structure offers significant advantages in terms of sealing technology compared to the 1 until 4 shown structure of the first embodiment of the hydraulic piston device 1, in which all four hollow cylinders 2, 5, 8, 11 are arranged completely separately from each other and correspondingly a higher sealing technology effort must be operated.

In a further exemplary embodiment of the hydraulic piston device 1, which is not shown in the figures, the diameter of the piston rod 14 varies over the length of the piston rod 14 in such a way that the piston rod 14 is immediately adjacent to the first piston 15 in the direction of the second piston 16 out has a larger diameter than immediately bar following the second piston 16 in the direction of the first piston 15 and that, in addition, the piston rod 14 immediately following the fourth piston 18 in the direction of the third piston 17 has a larger diameter than immediately following the third piston 17 in Direction to the fourth piston 18 out. Such a design measure provides even further improved support for the gas or air compression.

Although the individual specific exemplary embodiments of the hydraulic piston device 1 described in more detail here have been explained above, above all with reference to the use or compression of the gas air, it should be emphasized at this point that any other gas, for example Biogas and/or methane and/or any hydrocarbon gas and/or a mixture of hydrocarbon gases and/or a mixture of air and one or more hydrocarbon gases can be used in the hydraulic piston device 1 and compressed by it.

The same applies to the naming of oil as the liquid to be used in the hydraulic piston device 1 . Although oil is often used as a liquid in the hydraulic piston device 1 for purely economic reasons, the operation of the hydraulic piston device 1 is in principle also readily possible with any other liquid, for example water.

The use of the hydraulic piston device 1 for the purpose of gas compression has been described above, and the hydraulic piston device 1 is always designed and suitable for this purpose.

However, the known as such from the prior art hydraulic piston device 1 can also be an essential part as such also from the prior art, namely from the DE 10 2019 002 370 A1 known compressed gas energy conversion device 50 and then not only - as described above - are operated in the gas compression mode, but also vice versa, namely in the gas expansion mode.

5 shows a first embodiment of the compressed gas energy conversion device 50, and 7 shows a second embodiment of the compressed gas energy conversion device 50. The difference between these two just mentioned embodiments of the compressed gas energy conversion device 50 is that in 5 shown first embodiment of the compressed gas energy conversion device 50 is constructed on the basis of in the 1 until 4 illustrated first embodiment of the hydraulic piston device 1 and in 7 shown second embodiment of the compressed gas energy conversion device 50 is constructed on the basis of in 6 illustrated second embodiment of the hydraulic piston device 1.

Since both the first exemplary embodiment of the hydraulic piston device 1 and the second exemplary embodiment of the hydraulic piston device 1 have already been described in great detail above, the 5 and 7 are considered together, and in the following the focus is placed solely on the description of those components of compressed gas energy conversion device 50 which are identical in the first exemplary embodiment of compressed gas energy conversion device 50 and in the second exemplary embodiment of compressed gas energy conversion device 50, so that in the following there is no further distinction between the 5 and 7 or between the first exemplary embodiment of the compressed gas energy conversion device 50 and the second exemplary embodiment of the compressed gas energy conversion device 50 .

The compressed gas energy conversion device 50 has a hydraulic piston device 1 as an essential component, the latter being able to be constructed, for example, like the first exemplary embodiment of the hydraulic piston device 1 already described in detail above (cf 5 ) or, for example, like the second exemplary embodiment of the hydraulic piston device 1 already described in detail above (cf 7 ). The compressed gas energy conversion device 50 also has a compressed gas storage device--not shown in the figures--and a liquid storage device--also not shown in the figures.

The eleventh gas connection device 45 is connected to the compressed gas storage device and set up by means of the valve device belonging to the eleventh gas connection device 45 in such a way that the eleventh gas connection device 45 is used for introducing compressed gas from the compressed gas storage device into the third chamber 21 when the valve is set appropriately.

The twelfth gas connection device 46 is connected to the compressed gas storage device and set up by means of the valve device belonging to the twelfth gas connection device 46 such that the twelfth gas connection device 46 with a correspondingly suitable valve setting for one lead compressed gas from the compressed gas storage device in the sixth chamber 24 is used.

The second liquid connection device 28 is connected to the liquid storage device and is set up by means of the valve device belonging to the second liquid connection device 28 in such a way that the second liquid connection device 28 is used to suck liquid from the liquid storage device into the fourth chamber 22 when the valve position is appropriate.

The fourth liquid connection device 30 is connected to the liquid storage device and is set up by means of the valve device belonging to the fourth liquid connection device 30 in such a way that the fourth liquid connection device 30 is used for sucking liquid from the liquid storage device into the fifth chamber 23 with a correspondingly suitable valve setting.

The first liquid connection device 27 is set up by means of the associated valve device in such a way that the first liquid connection device 27, with a correspondingly suitable valve setting, serves to introduce liquid from the fourth chamber 22 into a first liquid line 47, which is designed in such a way that it can be introduced into it and liquid flowing through it to a machine 48 to be driven by the flowing liquid, wherein this machine 48 can be, for example, a drive device for an electrical energy generator.

The third liquid connection device 29 is set up by means of the associated valve device in such a way that the third liquid connection device 29, with a correspondingly suitable valve setting, is used to introduce liquid from the fifth chamber 23 into a second liquid line 49, which is set up in such a way that it can be introduced into it and liquid flowing through it to a machine 48 to be driven by the flowing liquid, which machine can be, for example, a drive device for an electrical energy generator.

The tenth gas connection device 42 is set up by means of the associated valve device in such a way that the tenth gas connection device 42 serves to introduce gas from the third chamber 21 into a fifth gas line 51 with a correspondingly suitable valve setting.

There is also a first pressure control valve device 52, which regulates gas pressure and liquid pressure against one another, is connected to the fifth gas line 51 on the gas side by means of a sixth gas line 53 and is connected to the second liquid line 49 on the liquid side by means of a third liquid line 54.

The fifth gas connection device 35 is set up by means of the associated valve device in such a way that the fifth gas connection device 35 serves to introduce gas from the sixth chamber 24 into a seventh gas line 55 with a correspondingly suitable valve setting.

There is also a second pressure control valve device 56, which regulates gas pressure and liquid pressure against one another, is connected to the seventh gas line 55 on the gas side by means of an eighth gas line 57 and is connected to the first liquid line 47 on the liquid side by means of a fourth liquid line 58.

The fifth gas line 51 also leads to a consumer device 59 which uses gas from the fifth gas line 51 thermally and/or mechanically and/or chemically.

The seventh gas line 55 also leads to a consumer device 59, which originates from the seventh gas line 55 and uses gas thermally and/or mechanically and/or chemically.

As in the case of the hydraulic piston device 1 described in detail further above, the compressed gas energy conversion device 50 can of course also use air as the gas, for example. However, it is also just as possible with compressed gas energy conversion device 50 for any other gas, for example biogas and/or methane and/or any hydrocarbon gas and/or a mixture of hydrocarbon gases and/or a mixture of air, instead of or together with air and one or more hydrocarbon gases can be used in the hydraulic piston device 1.

The same applies to the liquid to be used in the compressed gas energy conversion device 50 . Although oil is often used as the liquid in the compressed gas energy conversion device 50 for purely practical economic reasons, the compressed gas energy conversion device 50 can in principle also be operated with any other liquid, for example water.

Both exemplary embodiments of the compressed gas energy conversion device 50 described above from a purely structural point of view function as follows:

Imagine that, based on the views of the 5 and the 7 , initially the piston rod 14 may be in its most left-shifted position. Accordingly, the first chamber 19, the third chamber 21, the fifth chamber 23 and the seventh chamber 25 initially each have their smallest possible volume, while the second chamber 20, the fourth chamber 22, the sixth chamber 24 and the eighth chamber 26 initially their respective have the largest possible volume. The second chamber 20, sixth chamber 24 and eighth chamber 26 are each initially filled with gas, while the fourth chamber 22 is initially filled with liquid. Air may be used as the gas in the exemplary embodiments of the compressed gas energy conversion device 50 to be described here, and oil may be used as the liquid in the exemplary embodiments of the compressed gas energy conversion device 50 to be described here.

The valve device belonging to the first gas connection device 31, the valve device belonging to the second gas connection device 32, the valve device belonging to the third gas connection device 33, the valve device belonging to the fourth gas connection device 34, the valve device belonging to the sixth gas connection device 38, the valve device belonging to the seventh gas connection device 39 belonging valve device, the valve device belonging to the eighth gas connection device 40 and the valve device belonging to the ninth gas connection device 41 are open and remain - at least for the purposes of the following functional description of the two in the 5 or. 7 shown embodiments of the compressed gas energy conversion device 50 - also constantly open. As can be seen from the following functional description of the two in the 5 or. 7 As will be readily apparent from the exemplary embodiments of compressed gas energy conversion device 50 shown, the first chamber 19, the second chamber 20, the seventh chamber 25 and the eighth chamber 26 can, for example, simply be used to collect compressed air from the compressed air storage device that is relaxing and consequently cooling to pass cold air through to a consumer, or they can--when the compressed gas energy conversion device 50 is operated in a warm environment or in a warm part of the environment--can be used to simply draw in warm outside air and pass it through to a consumer of warm air. However, the options mentioned in the previous paragraph are only possible side effects which—if desired—can also be used during the operation of the compressed gas energy conversion device 50, but do not necessarily have to be used.

However, the second hollow cylinder 5 with the third chamber 21 and the fourth chamber 22 and the third hollow cylinder 8 with the fifth chamber 23 and the sixth chamber 24 are absolutely essential for the operation of the compressed gas energy conversion device 50.

The valve device belonging to the tenth gas connection device 42 is initially closed. The valve device belonging to the twelfth gas connection device 46 is initially also closed. The valve device belonging to the second liquid connection device 28 is initially closed, while the valve device belonging to the first liquid connection device 27 is initially open. The valve device associated with the third fluid connection device 29 is initially closed, and the valve device associated with the fourth fluid connection device 30 is initially open.

The valve device belonging to the fifth gas connection device 35 is initially open. The valve device belonging to the eleventh gas connection device 45 is also initially open. Accordingly, compressed air is introduced from the compressed air storage device through the eleventh gas connection device 45 into the third chamber 21, with the result that the piston rod 14 with the four pistons 15, 16, 17, 18 fixed to it in the views of FIG 5 or. 7 moved to the right. Accordingly, air is pressed out of the sixth chamber 24 through the fifth gas connection device 35 and fed via the seventh gas line 55 to the consumer device 59, which uses the air thermally and/or mechanically and/or chemically. The consumer device 59 just mentioned can be, for example, a turbine driving an electric generator or, for example, an exemplary embodiment of a compressed gas energy conversion heat exchanger device 60, 146 to be described further below or, for example, an exemplary embodiment of a compressed gas energy conversion heat exchanger device preliminary stage device 137 to be described further below. 138, 149 or, for example, an exemplary embodiment of a compressed gas energy conversion device to be described further below. At the same time, the air pressed out of the sixth chamber 24 is present via the eighth gas line 57 on the air side of the second pressure control valve device 56, which regulates air pressure and oil pressure against one another.

During the above-mentioned movement of the piston rod 14 with the four pistons 15, 16, 17, 18 fixed to it in the views of FIG 5 or. 7 oil is also pressed out of the fourth chamber 22 to the right and passes through the first fluid connection device 27 and the first fluid sigkeitsleitung 47 to be driven by flowing oil machine 48, which can be, for example, an electric generator driving turbine. The oil flow through the first liquid line 47 is controlled via the second pressure control valve device 56, which regulates air pressure and oil pressure against one another, because the first liquid connection device 27 communicates via the first liquid line 47, the fourth liquid line 58 branching off therefrom, and the second pressure control valve device 56, which supplies air pressure and oil pressure against each other, with the fifth gas connection device 35.

In addition, in the movement just mentioned, the piston rod 14 with the four pistons 15, 16, 17, 18 fixed to it in the views of FIG 5 or. 7 sucked to the right oil from the oil storage device via the fourth liquid connection device 30 into the fifth chamber 23 inside.

Once in the views of 5 or. 7 When the piston rod 14 with the four pistons 15, 16, 17, 18 fixed to it has reached its rightmost position, the first chamber 19, the third chamber 21, the fifth chamber 23 and the seventh chamber 25 each have their largest possible volume , while the second chamber 20, the fourth chamber 22, the sixth chamber 24 and the eighth chamber 26 have each assumed their smallest possible volume. The first chamber 19, the third chamber 21 and the seventh chamber 25 are each filled with air, while the fifth chamber 23 is filled with oil.

The valve device belonging to the tenth gas connection device 42 is opened. The valve device 35 belonging to the fifth gas connection device 35 is closed. The valve device 46 belonging to the twelfth gas connection device is opened. The valve device belonging to the fourth liquid connection device 30 is closed.

Accordingly, air is pressed out of the third chamber 21 through the tenth gas connection device 42 and fed via the fifth gas line 51 to the consumer device 59, which uses the air thermally and/or mechanically and/or chemically. At the same time, the air pressed out of the third chamber 21 is present via the sixth gas line 53 on the air side of the first pressure control valve device 52, which controls the air pressure and oil pressure against one another.

During the above-mentioned movement of the piston rod 14 with the four pistons 15, 16, 17, 18 fixed to it in the views of FIG 5 or. 7 to the left, oil is also pressed out of the fifth chamber 23 and reaches the machine 48 to be driven by flowing oil via the third liquid connection device 29 and the second liquid line 49, which machine can be, for example, a turbine driving an electric generator. The oil flow through the second liquid line 49 is controlled via the first pressure control valve device 52, which regulates air pressure and oil pressure against one another, because the third liquid connection device 29 communicates via the second liquid line 49, the third liquid line 54 branching off from it, and the first pressure control valve device 52, which regulates air pressure and oil pressure against each other, with the tenth gas connection device 42.

In addition, in the movement just mentioned, the piston rod 14 with the four pistons 15, 16, 17, 18 fixed to it in the views of FIG 5 or. 7 Oil is sucked to the left from the oil storage device via the second liquid connection device 28 into the fourth chamber 22 .

Once in the views of 5 or. 7 the piston rod 14 with the four pistons 15, 16, 17, 18 fixed to it has again reached its position, which has been moved as far to the left as possible, the first chamber 19, the third chamber 21, the fifth chamber 23 and the seventh chamber 25 each have their respective positions again assumed the smallest possible volume, while the second chamber 20, the fourth chamber 22, the sixth chamber 24 and the eighth chamber 26 have each assumed their largest possible volume again. The second chamber 20, the sixth chamber 24 and the eighth chamber 26 are each filled with air, while the fourth chamber 22 is filled with oil.

The valve devices are now switched back to their respective initial position, namely as follows: The valve device belonging to the eleventh gas connection device 45 will be opened. The valve device belonging to the tenth gas connection device 42 is closed. The valve device belonging to the fifth gas connection device 35 is opened.

The valve device belonging to the second liquid connection device 28 is closed. The valve device belonging to the first liquid connection device 27 is opened. The valve device belonging to the third liquid connection device 29 is closed.

Accordingly, compressed air from the compressed air storage device is again introduced through the eleventh gas connection device 45 into the third chamber 21, which means that the piston rod 14 with the four pistons 15, 16, 17, 18 fixed to it in the views of FIGS 5 or. 7 moves to the right and the corresponding functional sequence is repeated as already described above with regard to the corresponding movement of the piston rod 14 to the right.

The piston rod 14 moves back and forth with the four pistons 15, 16, 17, 18 fixed to it and converts the energy stored in the compressed air storage device in the form of compressed air in the consumer device 59, which uses gas thermally and/or mechanically and/or or used chemically, as well as in the machine 48 to be driven by flowing liquid into other forms of energy.

• Es wird für das vorliegende Ausführungsbeispiel davon ausgegangen, dass die Druckgasenergiewandlungs-Wärmetauscher-Einrichtung 60 senkrechtstehend montiert ist, die erste Flüssigkeitsleitung 81 sich also ausgehend von dem zweiten Hohlzylinder 66 nach oben erstreckt und der vierte Hohlzylinder 68 - oben verschraubt mit dem ersten Kolben 69 und unten verschraubt mit dem zweiten Kolben 70 - sich am unteren Totpunkt befindet.

Die zur dritten Flüssigkeitsleitung 97 gehörende Ventileinrichtung ist geöffnet und ermöglicht daher bei einem Hub des ersten Kolbens 69 nach oben ein Ansaugen von Öl aus dem Öltank in die fünfte Kammer 75, und zwar über die vierte Flüssigkeitsleitung 82, den dritten Hohlzylinder 67, den zweiten Hohlzylinder 66 und die erste Flüssigkeitsleitung 81.

That in the 8th , 9 and 10 The embodiment shown of the compressed gas energy conversion heat exchanger device 60 works as follows:

• For the present exemplary embodiment, it is assumed that the compressed gas energy conversion heat exchanger device 60 is mounted vertically, i.e. the first liquid line 81 extends upwards, starting from the second hollow cylinder 66, and the fourth hollow cylinder 68 is screwed to the first piston 69 at the top and bolted down to the second piston 70 - is at bottom dead center. The first piston 69 rests against the first center part 64 and the second center part 65 , and the second piston 70 rests against the second end wall 63 . The fourth liquid line 82 is at its end facing away from the third hollow cylinder 67 to a in the 8th , 9 and 10 not shown oil tank connected. The valve device belonging to the third liquid line 97 is open and therefore allows oil to be sucked in from the oil tank into the fifth chamber 75 when the first piston 69 strokes upwards, specifically via the fourth liquid line 82, the third hollow cylinder 67, the second hollow cylinder 66 and the first liquid line 81. The valve device belonging to the second liquid line 96 is closed, and the valve device belonging to the fifth liquid line 94 is also closed. The valve device belonging to the sixth liquid line 95 is open.

In the present exemplary embodiment of the compressed gas energy conversion heat exchanger device 60, the sixth liquid line 95 leads to a motor which is driven by the oil which is pressed up through the sixth liquid line 95 towards the second piston 70 when it strokes. The one pushed through the sixth liquid line 95 Generally speaking, oil is used to do work.

The valve device belonging to the first gas connection device 98 is opened so that when the first piston 69 lifts upwards, the air in the first chamber 71 can escape from the first chamber 71 via the first gas connection device 98 . The first chamber 71 is then simply vented to the outside atmosphere, or the partially expanded air pressed out of the first chamber 71 is routed to the next consumer, with the next consumer just mentioned also being a compressed gas energy conversion heat exchanger device 60, 146 in terms of equipment, for example or, for example, an exemplary embodiment of a compressed gas energy conversion heat exchanger device preliminary stage device 137, 138, 149 to be described further below or, for example, an exemplary embodiment of a compressed gas energy conversion device to be described further below.

The second gas line 78 is also open for forwarding air to the next consumer, which, as already mentioned, can, for example, also be a compressed gas energy conversion heat exchanger device 60, 146 or, for example, an exemplary embodiment of a compressed gas energy conversion heat exchanger device to be described further below. Device precursor device 137, 138, 149 or, for example, an exemplary embodiment of a compressed gas energy conversion device to be described further below.

Compressed air from a cylinder of a preliminary stage or a similar device, for example from an exemplary embodiment of the hydraulic piston device 1 or from an exemplary embodiment of the compressed gas energy conversion device 50, is now conducted via the first gas line 77 into the fifth chamber 75 in an optimized quantity and pressure. The air expands there and pushes the fourth hollow cylinder 68 with the first piston 69 and the second piston 70 upwards. At the same time, air with the same or different pressure can be fed into the second chamber 72 via the second gas connection device 99 . This air acts on the second piston 70 and increases the force with which the fourth hollow cylinder 68 is pushed upwards. Meanwhile, the fourth chamber 74 was filled with warm oil. During this "work cycle" with the piston stroke direction upwards, the third chamber 73 is again sucked full of warm oil via the third liquid line 97 from the oil tank. This oil is further sucked via the fourth liquid line 82 through the third hollow cylinder 67 , through the second central part 65 and through the second hollow cylinder 66 into the first liquid line 81 . At the same time, the oil is pressed out of the fourth chamber 74 via the sixth fluid line 95 to the consumer or to the engine driven by oil. This process lasts until the first piston 69 reaches the first end wall 62, ie top dead center.

As soon as the first piston 69 has reached the first end wall 62, i.e. top dead center, the valve device belonging to the second liquid line 96 opens, the valve device belonging to the third liquid line 97 closes, the valve device belonging to the fifth liquid line 94 opens and closes the valve device belonging to the valve device belonging to the sixth liquid line 95 .

Now the "working stroke" begins with the piston stroke direction downwards, which basically runs as a mirror image of the "working stroke" described in the penultimate paragraph with the piston stroke direction upwards: Compressed air is now supplied via the first gas connection device 98 and the second gas line 78. The first gas line 77 opens to the next consumer. The second gas connection device 99 vents or goes to the next consumer. Oil is now forced through the fifth fluid line 94 to the oil driven motor due to the downward movement of the first piston 69 .

Based on 11 a further functional example of the operation of a compressed gas energy conversion heat exchanger device 60 will now be described. 11 shows schematically and not to scale the longitudinal section through the exemplary embodiment of the compressed gas energy conversion heat exchanger device from FIG 8th , where in 11 additionally supply lines for gas are shown.

Also in the example of 11 Air is used as the gas and oil as the liquid, and the expanding air is heated by the warm oil to prevent icing.

Compressed air is fed into the fifth chamber 75 via a first compressed gas supply line 100 and the first gas line 77 . The quantity resulting from the pressure of the compressed air introduced is measured in such a way that after the last expansion stage has been reached, the pressure is reached that is necessary to serve the next consumer or to ensure that the desired air temperature is reached.

The fourth hollow cylinder 68 with the second piston 70 and the first piston 69 is pushed upwards. Here, oil from the fourth chamber 74 via the sixth fluid line 95 to Motor / consumers led. At the same time, the third chamber 73 is filled with oil from the oil tank via the third liquid line 97. The first gas connection device 98 is opened from the first chamber 71 to the consumer via a first exhaust air line 104.

A second compressed gas supply line 101 is closed, a third gas line 102 is closed and a fourth gas line 103 is open.

Air flows from the sixth chamber 76 via the second gas line 78 via the fourth gas line 103 and the second gas connection device 99 into the second chamber 72. Pressure equalization occurs in the sixth chamber 76 and the second chamber 72. A second exhaust air line 105 is closed.

When the fourth hollow cylinder 68 has reached top dead center with its first piston 69 and the second piston 70, the first compressed gas supply line 100 and the first exhaust air line 104 close and the third gas line 102 opens.

Compressed air now flows from the fifth chamber 75 into the first chamber 71 and equalizes the pressure.

The fourth gas line 103 now closes and the second exhaust air line 105 and the second compressed gas supply line 101 open.

Compressed air is now fed into the sixth chamber 76 via the second compressed gas supply line 101 and the second gas line 78 . This results in the fourth hollow cylinder 68 being pressed downwards with the first piston 69 and the second piston 70 . In the process, oil is routed from the third chamber 73 via the fifth fluid line 94 to the engine/consumer. At the same time, the fourth chamber 74 is sucked full of oil from the oil tank via the second liquid line 96.

With this circuit, the "energy yield" from the displaced oil is very low in the sense that the kinetic energy that can be obtained from the displaced oil for possible conversion into electrical energy is very low, because the circuit works with dynamic pressure and the movement of the oil is correspondingly slow displaced oil.

16 shows an embodiment of a compressed gas energy conversion heat exchanger device 146 according to the invention, which compared to the above with reference to the 8th until 11 described, known from the prior art embodiment of the compressed gas energy conversion heat exchanger device 60 is provided with some additional components that allow a certain control of the operation of the compressed gas energy conversion heat exchanger device 146 in thermal terms. The background to this additional technical measure is that with regard to ambient temperatures that change over time at the place of use of a compressed gas energy conversion heat exchanger device and/or with regard to operating requirements that may change over time in the technical and technological environment of a compressed gas energy conversion heat exchanger device during the use of the Compressed gas energy conversion heat exchanger device can be useful and sometimes may even be absolutely necessary to specifically control the temperature of the exhaust air or exhaust gas. While, for example, in the depths of winter with very cold outside temperatures, it can be quite advantageous to have the highest possible exhaust air temperature, so that the compressed gas energy conversion heat exchanger device does not partially freeze and the exhaust air can perhaps even be used to heat any rooms, the same high exhaust air temperature be useless or even counterproductive and completely undesirable in midsummer with high outside temperatures. At least the risk of a partial freezing of the compressed gas energy conversion heat exchanger device is lower in midsummer than in the dead of winter, and it can therefore be advantageous from an energetic point of view when considering the overall system in which the compressed gas energy conversion heat exchanger device is used, more in summer To keep heat in the oil for further use there, while in winter it may well be necessary to transfer more heat from the oil to the air or to the other gas, if used. If the exhaust air temperature is too high, an unnecessarily large amount of energy in the form of heat is withdrawn from the oil or the liquid as a heat transfer medium. Accordingly, the provision of a thermal control capability is advantageous and desirable. For this purpose, the in 16 illustrated embodiment of the compressed gas energy conversion heat exchanger device 146 according to the invention in addition to the in 8th components already shown, the following is provided: a seventh liquid line 147, one end of which is connected to the fourth liquid line 82 and set up such that this seventh liquid line 147 is able to transfer liquid from the fourth liquid line 82 to the second liquid line 96 and to the third liquid line 97 without the liquid passing through the third hollow cylinder 67, the liquid conduction device 85 and the second hollow cylinder 66 on its way to the second liquid line 96 and to the third liquid line 97, with the connection of the seventh liquid line 147 to the fourth liquid line device 82 is provided with a flow control valve device 148, which is controllable and designed in such a way that the flow control valve device 148 can be used to control what proportion of a liquid flow arriving from the liquid tank via the fourth liquid line 82 at the flow control valve device 148 into the third hollow cylinder 67 and what proportion into the seventh liquid line 147, with the ability of the flow control valve device 148 to control at least the possibility of controlling whether the liquid flow arriving at it via the fourth liquid line 82 is fed completely into the third hollow cylinder 67 or completely into the seventh liquid line 147. That's in 16 The special exemplary embodiment of the compressed gas energy conversion heat exchanger device 146 according to the invention that is shown is specially set up in such a way that here the seventh liquid line 147 opens into the first liquid line 81 with its end remote from the flow control valve device 148 .

The flow control valve assembly 148 may include a thermostatic valve, for example.

Provision is particularly preferably made for the flow control valve device 148 to be set up in such a way that, in addition to the already mentioned control option for the complete introduction of the liquid flow arriving at it via the fourth liquid line 82, it can also be controlled either into the third hollow cylinder 67 or into the seventh liquid line 147 that it can divide the liquid flow arriving at it via the fourth liquid line 82, so that part of the liquid gets into the third hollow cylinder 67 and at the same time another part of the liquid gets into the seventh liquid line 147, with an associated flow distribution ratio being stepless and/or in levels can be controlled. In this case, the flow control valve device 148 controls the liquid flow as a function of a gas and/or liquid temperature measurement. If the control just mentioned is to be based on a gas temperature measurement, this can in principle be carried out at any point at which the gas flows. A temperature measurement is preferred where the gas has already “worked”, i.e. has already expanded.

Advantageously, this measurement or measurements just mentioned is or are set up, for example, in such a way that, if a gas temperature measurement is carried out to control the flow control valve device 148, this gas temperature measurement is carried out at least in a region of the first gas line 77 which is further away from the second central part 65 than from the third end wall 79, and that, if a liquid temperature measurement is taken to control the flow control valve device 148, this liquid temperature measurement takes place at least either in the first liquid line 81 or in an area of the second hollow cylinder 66 which is spaced further away from the second central part 65 than from the third end wall 79.

The flow control valve device 148 can be controlled, for example, mechanically and/or electromechanically and/or magnetically and/or electromagnetically and/or electronically and/or optically and/or electro-optically and/or in any other technically suitable manner.

The control of the 16 The illustrated special exemplary embodiment of the compressed gas energy conversion heat exchanger device 146 according to the invention from a thermal point of view can, for example, take place as follows: First, the flow control valve device 148, which can be a thermostatic valve, is set in such a way that all oil arriving at that thermostatic valve via the fourth liquid line 82 is exactly as in the embodiment of 8th permanently provided and in that embodiment due to the technical structure provided there otherwise not possible, is directed into the third hollow cylinder 67 and from there exactly as it is above with reference to 8th was described, moved on. If a measurement of the temperature of the exhaust air, which takes place in the area of the first gas line 77 where the first gas line 77 penetrates the third end wall 79, determines that the temperature of the exhaust air is higher than is necessary or permitted on the basis of any previously defined conditions, the thermostatic valve mentioned in the previous sentence is controlled mechanically or electromechanically in such a way that it completely or partially interrupts the oil supply from the fourth fluid line 82 to the third hollow cylinder 67 and instead the oil arriving from the fourth fluid line 82 is fully or partially fed into the seventh liquid line 147 and from there then into the second liquid line 96 and the third liquid line 97. The oil as such reaches the second liquid line 96 and the third liquid line 97 both in the embodiment of FIG 8th as well as in the embodiment of FIG 16 always. While in the embodiment of FIG 8th however, there is permanently only one way for the oil to go there, in the embodiment of FIG 16 for the oil two different ways to the second liquid line 96 and the third liquid sigkeitsleitung 97, which can be controlled, which path the oil should take or how the oil is distributed in terms of quantity on the two possible paths. The less oil flows into the third hollow cylinder 67 and from there via the liquid ducting device 85 to the second hollow cylinder 66, the less heat can be transferred there - i.e. in the "piston interior" - from the oil to the air flowing through the second gas line 78 and the first gas line 77 will. If the flow of oil is completely interrupted in the way just mentioned, this accordingly results in an interruption in the supply of heat to the air flowing through the second gas line 78 and the first gas line 77 . The temperature of the exhaust air drops accordingly if - as already described in this paragraph a little further above - the aforementioned thermostatic valve - i.e. the flow control valve device 148 - completely or partially interrupts the oil supply from the fourth liquid line 82 into the third hollow cylinder 67 and instead switches it off the fourth liquid line 82 leads the oil arriving in full or in part into the seventh liquid line 147 . The exhaust air is then heated less, is discharged "cooler" into the environment or used for other purposes. If at some point later the exhaust air temperature should be considered to be too low, the position of said thermostatic valve - ie the flow control valve device 148 - can then be changed in such a way that more or even all of the oil which arrives at the flow control valve device 148 via the fourth liquid line 82 passed into the third hollow cylinder 67 and in this way the air flowing in the second gas line 78 and in the first gas line 77 is supplied with heat or more heat.

• Es befindet sich anfänglich in der vierten Kammer 116 Öl und in der ersten Kammer 113 Luft. Die zu der ersten Gasanschlusseinrichtung 117 gehörende Ventileinrichtung ist geöffnet derart, dass Luft aus der ersten Kammer 113 über die erste Gasanschlusseinrichtung 117 entweichen kann. Die zu der zweiten Gasanschlusseinrichtung 118 gehörende Ventileinrichtung ist geöffnet derart, dass Druckluft durch die zweite Gasanschlusseinrichtung 118 in die dritte Kammer 114 hineingeführt werden kann. Die zu der zweiten Flüssigkeitsanschlusseinrichtung 122 gehörende Ventileinrichtung ist geschlossen. Die zu der vierten Flüssigkeitsanschlusseinrichtung 120 gehörende Ventileinrichtung ist geöffnet. Die zu der ersten Flüssigkeitsanschlusseinrichtung 121 gehörende Ventileinrichtung ist geöffnet, und die zu der dritten Flüssigkeitsanschlusseinrichtung 119 gehörende Ventileinrichtung ist geschlossen.

If it is assumed that in the exemplary embodiments of the compressed gas energy conversion heat exchanger device preliminary stage device 137, 138, 149 to be described here, air is used as the gas and oil is used as the liquid and that the first exemplary embodiment of the compressed gas energy conversion heat exchanger device preliminary stage device 137 to be described here as in 12 shown with the first hollow cylinder 106 standing vertically with the second end wall 108 at the bottom and the first end wall 107 at the top and the piston rod 109 with the second piston 111 fixed thereon and the first piston 110 fixed thereon initially in position at its lower end Dead center is, this first embodiment of the compressed gas energy works conversion heat exchanger device pre-stage device 137 as follows:

• There is initially oil in the fourth chamber 116 and air in the first chamber 113 . The valve device belonging to the first gas connection device 117 is open in such a way that air can escape from the first chamber 113 via the first gas connection device 117 . The valve device belonging to the second gas connection device 118 is open in such a way that compressed air can be fed through the second gas connection device 118 into the third chamber 114 . The valve device belonging to the second fluid connection device 122 is closed. The valve device belonging to the fourth liquid connection device 120 is open. The valve device belonging to the first liquid connection device 121 is open, and the valve device belonging to the third liquid connection device 119 is closed.

Compressed air is now introduced into the third chamber 114 through the second gas connection device 118 , which causes the piston rod 109 together with the first piston 110 and the second piston 111 to be raised. Accordingly, the air in the first chamber 113 is pushed out through the first gas port 117, the oil in the fourth chamber 116 is pushed out through the fourth fluid port 120, and oil is sucked into the second chamber 115 through the first fluid port 121. Although the compressed air expanded into the third chamber 114 cools down during expansion, heat exchange takes place through the second piston 111 with the oil in the fourth chamber 116, which is usually warm or at least has room temperature, so that on this In any case, the temperature drop in the air during relaxation is mitigated.

As soon as the piston rod 109 with the second piston 111 fixed on it and the first piston 110 fixed on it has reached its top dead center, the valve device belonging to the first gas connection device 117 is switched in such a way that compressed air enters the first chamber 113 through the first gas connection device 117 can be introduced. The valve device belonging to the second gas connection device 118 is switched in such a way that the air can be guided out of the third chamber 114 through the second gas connection device 118 . The valve device belonging to the second liquid connection device 122 is opened. The valve device belonging to the fourth liquid connection device 120 is closed. The valve device belonging to the first liquid connection device 121 is closed and the valve device belonging to the third liquid connection device 119 is opened.

Compressed air is now introduced into the first chamber 113 through the first gas connection device 117, which leads to a downward stroke of the piston rod 109 together with the first piston 110 and the second piston 111. Accordingly, the air in the third chamber 114 is pushed out through the second gas port 118, the oil in the second chamber 115 is pushed out through the third fluid port 119, and oil is drawn into the fourth chamber 116 through the second fluid port 122. Although the compressed air expanded into the first chamber 113 cools down during expansion, heat is exchanged through the first piston 110 with the oil in the second chamber 115, which is usually warm or at least has room temperature, so that In any case, the temperature drop in the air during relaxation is mitigated.

As soon as the piston rod 109 with the second piston 111 fixed on it and the first piston 110 fixed on it has reached its bottom dead center again, the valve device belonging to the second gas connection device 118 is switched over again in such a way that compressed air flows through the second gas connection device 118 into the third chamber 114 can be introduced. The valve device belonging to the first gas connection device 117 is switched in such a way that air can escape from the first chamber 113 via the first gas connection device 117 . The valve device belonging to the second liquid connection device 122 is closed. The valve device belonging to the fourth liquid connection device 120 is opened. The valve device belonging to the first liquid connection device 121 is opened and the valve device belonging to the third liquid connection device 119 is closed.

Compressed air is then let in again through the second gas connection device 118 into the third chamber 114, and the above-described lifting cycle of the piston rod 109 together with the first piston 110 and the second piston 111 begins again.

This in 13 The second exemplary embodiment shown of the compressed gas energy conversion heat exchanger device-preliminary device 138 differs in some details from the first exemplary embodiment of the compressed gas energy conversion heat exchanger described above shear device-precursor device 137, but like or substantially like parts are in the 12 and 13 each provided with the same reference numerals.

This in 13 illustrated second embodiment of the compressed gas energy conversion heat exchanger device preliminary device 138 has compared to in 12 The illustrated first exemplary embodiment of the compressed gas energy conversion heat exchanger device preliminary stage device 137 also has a second hollow cylinder 124, which is arranged inside the first hollow cylinder 106, extends through the opening in the central part 112 and at one end extends through an opening in the first End wall 107 and extends at its other end through an opening in the second end wall 108 through the first end wall 107 and the second end wall 108 addition. A further special feature of the second exemplary embodiment of the compressed gas energy conversion heat exchanger device preliminary stage device 138 is that the piston rod is designed as a piston tube 123 which encloses the second hollow cylinder 124, hydraulically-pneumatically seals against the second hollow cylinder 124 and is designed in such a way that it can slide back and forth on the second hollow cylinder 124 . Accordingly, of course, both the first piston 110 and the second piston 111 are each provided with a hole through which the second hollow cylinder 124 extends, and both the first piston 110 and the second piston 111 nestle hydraulically-pneumatically sealingly against the second hollow cylinder 124 and are designed in such a way that they can slide back and forth on the second hollow cylinder 124 together with the piston tube 123 on which they are respectively fixed. Furthermore, as a special feature of the second embodiment of the compressed gas energy conversion heat exchanger device preliminary stage device 138, a first liquid line 125 is provided which, for the purpose of liquid transport, is connected both to the first liquid connection device 121 and to the second liquid connection device 122 and to that end of the second hollow cylinder 124, which projects beyond the first end wall 107, is connected. Via a second liquid line 126, which for the purpose of transporting liquid is connected to that end of the second hollow cylinder 124 which protrudes beyond the second end wall 108, liquid, for example oil, can be pressed into the second hollow cylinder 124 and from there via the first liquid line 125 both flow towards the first liquid connection device 121 and also to the second liquid connection device 122 .

From a comparison of 12 and 13 It becomes immediately and readily clear that - apart from the purely constructive differences presented - the second exemplary embodiment of the compressed gas energy conversion heat exchanger device preliminary stage device 138 functions in principle in the same way as the first exemplary embodiment of the compressed gas energy conversion heat exchanger device described in detail above in terms of its function. Prestage device 137. However, due to the oil flowing through the second hollow cylinder 124 in the second exemplary embodiment of the compressed gas energy conversion heat exchanger device prestage device 138, a larger and better arranged surface area is available for the heat exchange between the liquid and the gas, so that in the second Embodiment of the compressed gas energy conversion heat exchanger device precursor device 138 effectively takes place during operation a much better heat exchange than in the first embodiment of the Dr Compressed gas energy conversion heat exchanger device pre-stage device 137.

17 shows an embodiment of a compressed gas energy conversion heat exchanger device preliminary device 149 according to the invention, which compared to the above with reference to the 13 described second embodiment of the compressed gas energy conversion heat exchanger device precursor device 138 is provided with some additional components that allow a certain control of the operation of the compressed gas energy conversion heat exchanger device precursor device 149 in thermal terms. The background to this additional technical measure is that with regard to ambient temperatures that change over time at the place of use of a compressed gas energy conversion heat exchanger device, preliminary device and/or with regard to operating requirements that may change over time in the technical-technological environment of a compressed gas energy conversion heat exchanger device, preliminary device During the use of the compressed gas energy conversion heat exchanger device, it can be useful and sometimes even absolutely necessary to control the temperature of the exhaust air or the exhaust gas in a targeted manner. While, for example, in the depths of winter when outside temperatures are very cold, it can be quite advantageous to have the highest possible exhaust air temperature, so that the compressed gas energy conversion heat exchanger device preliminary stage does not partially freeze and thus perhaps even - if, for example, the compressed gas energy conversion heat exchanger device preliminary stage device is autonomous ie without downstream compressed gas energy conversion heat exchanger device is operated - the exhaust air can be used to heat any premises, the same high exhaust air temperature in midsummer with high outside temperatures can be useless or even quite counterproductive and completely undesirable. At least the risk of partial freezing of the compressed gas energy conversion heat exchanger device preliminary device is lower in midsummer than in the dead of winter, and it can therefore be advantageous from an energetic point of view when considering the overall system in which the compressed gas energy conversion heat exchanger device preliminary stage device is used to leave more heat in the oil for further use in summer, while in winter it may well be necessary to transfer more heat from the oil to the air or to the other gas that may be used. If the exhaust air temperature is too high, an unnecessarily large amount of energy in the form of heat is withdrawn from the oil or the liquid as a heat transfer medium. Accordingly, the provision of a thermal control capability is advantageous and desirable. For this purpose, the in 17 illustrated embodiment of the compressed gas energy conversion heat exchanger device preliminary stage device 149 in addition to the in 13 components already shown, the following is provided: a third liquid line 150, one end of which is connected to the second liquid line 126 and set up in such a way that this third liquid line 150 is able to convey liquid from the second liquid line 126 to the first liquid connection device 121 and to the second liquid connection device 122 without the liquid passing through the second hollow cylinder 124 on its way to the first liquid connection device 121 and to the second liquid connection device 122, with the connection of the third liquid line 150 to the second liquid line 126 being provided with a flow control valve device 151, which is controllable and is designed in such a way that the flow control valve device 151 can be used to control which proportion of a liquid from the second liquid line 126 in the flow control valve device 15 1 incoming liquid flow into the second hollow cylinder 124 and which portion is routed into the third liquid line 150, the control option of the flow control valve device 151 including at least the possibility of controlling whether the liquid flow arriving at it via the second liquid line 126 is completely routed into the second hollow cylinder 124 or is directed completely into the third liquid line 150. That's in 17 The illustrated exemplary embodiment of the compressed gas energy conversion heat exchanger device according to the invention is specially set up in such a way that the third liquid line 150 opens into the first liquid line 125 with its end remote from the flow control valve device 151.

The flow control valve device 151 can have a thermostatic valve, for example.

Provision is particularly preferably made for the flow control valve device 151 to be set up in such a way that, in addition to the already mentioned possibility of controlling the complete introduction of the liquid flow arriving at it via the second liquid line 126, it can also be controlled either into the second hollow cylinder 124 or into the third liquid line 150 that it can divide the liquid flow arriving at it via the second liquid line 126, so that part of the liquid gets into the second hollow cylinder 124 and at the same time another part of the liquid gets into the third liquid line 150, with an associated flow splitting ratio being continuously variable and/or in levels can be controlled. In this case, the flow control valve device 151 controls the liquid flow as a function of a gas and/or liquid temperature measurement. If the control just mentioned is to be based on a gas temperature measurement, this can in principle be carried out at any point at which the gas flows. A temperature measurement is preferred where the gas has already “worked”, i.e. has already expanded.

Advantageously, this measurement or measurements just mentioned is or are set up such that, if a gas temperature measurement is carried out to control the flow control valve device 151, this gas temperature measurement is carried out at least either in the area of the first gas connection device 117 or in the area of the second gas connection device 118 or in one Area of the first chamber 113 which is spaced further from the central part 112 than from the first end wall 107 or in a region of the third chamber 114 which is spaced further from the central part 112 than from the second end wall 108, and that if a liquid temperature measurement is made to control the flow control valve means 151, this liquid temperature measurement is made at least either in the first liquid line 125 or in a region of the second hollow cylinder 124 which is further spaced from the central part 112 than from d he first end wall 107.

The control of the flow control valve device 151 can, for example, mecha mechanically and/or electromechanically and/or magnetically and/or electromagnetically and/or electronically and/or optically and/or electro-optically and/or in any other technically appropriate manner.

The control of the 17 The illustrated exemplary embodiment of the compressed gas energy conversion heat exchanger device preliminary stage device 149 according to the invention can, for example, take place as follows in thermal terms: First, the flow control valve device 151, which can be a thermostatic valve, is set in such a way that all oil arriving at that thermostatic valve via the second liquid line 126 is exactly as in the embodiment of FIG 13 permanently provided and in that embodiment due to the technical structure provided there otherwise not possible, is directed into the second hollow cylinder 124 and from there exactly as it is above with reference to 13 was described, moved on. If a measurement of the temperature of the exhaust air, which takes place in the area of the first gas connection device 117, determines that the temperature of the exhaust air is higher than is necessary or permitted based on any previously defined conditions, then the thermostatic valve mentioned in the previous sentence becomes mechanical or electromechanical controlled in such a way that it completely or partially interrupts the oil supply from the second fluid line 126 to the second hollow cylinder 124 and instead the oil arriving from the second fluid line 126 correspondingly completely or partially into the third fluid line 150 and from there to the first fluid connection device 121 and leads to the second liquid connection device 122 . The oil as such reaches the first liquid connection device 121 and the second liquid connection device 122 both in the exemplary embodiment in FIG 13 as well as in the embodiment of FIG 17 always. While in the embodiment of FIG 13 however, there is permanently only one way for the oil to go there, in the embodiment of FIG 17 two different paths for the oil to the first fluid connection device 121 and to the second fluid connection device 122, it being possible to control which path the oil should take or how the oil is distributed quantitatively over the two possible paths. The less oil flows into the second hollow cylinder 124 , the less heat can be transferred from the oil to the air in the third chamber 114 and in the first chamber 113 . If the flow of oil is completely interrupted in the way just mentioned, this accordingly results in an interruption in the supply of heat to the air located in the third chamber 114 and to the air in the first chamber 113 . Accordingly, the temperature of the exhaust air drops when - as already described in this paragraph a little further above - the aforementioned thermostatic valve - i.e. the flow control valve device 151 - completely or partially interrupts the oil supply from the second liquid line 126 into the second hollow cylinder 124 and instead switches it off the oil arriving in the second liquid line 126 leads in full or in part into the third liquid line 150. The exhaust air is then heated less, is discharged "cooler" into the environment or used for other purposes. If at some point later the exhaust air temperature should be considered too low, the position of said thermostatic valve - ie the flow control valve device 151 - can then be changed in such a way that more or even all of the oil that arrives at the flow control valve device 151 via the second liquid line 126 passed into the second hollow cylinder 124 and in this way the air in the third chamber 114 and the air in the first chamber 113 is supplied with heat or more heat.

With reference to the 14 and 15 exemplary embodiments of compressed gas energy conversion devices are described below.

A compressed gas energy conversion device according to the invention stands out from the compressed gas energy conversion devices known from the prior art in that it has at least one group of two, which has a compressed gas energy conversion heat exchanger device according to the invention and a compressed gas energy conversion heat exchanger device according to the invention, which the compressed gas energy conversion heat exchanger device as Preliminary stage is operationally upstream, has. In this case, it is particularly preferred to provide two, three, four or more of the groups of two mentioned, these groups of two being combined and interconnected with one another.

Air, for example, can also be used as the gas in the compressed gas energy conversion device according to the invention. But it is also just as possible that instead of or together with air, any other gas, for example biogas and/or methane and/or any hydrocarbon gas and/or a mixture of hydrocarbon gases and/or a mixture of air and one or more Hydrocarbon gases can be used.

With regard to the liquid to be used, oil is often used as the liquid in the compressed gas energy conversion device according to the invention for purely economic reasons, but the operation of the compressed gas energy conversion device according to the invention is in principle without further also possible with any other liquid, for example with water.

The purpose of the compressed gas energy conversion device according to the invention in its various exemplary embodiments is always to provide possible interconnections and combinations of energy conversion devices working with compressed gas to form a combined unit with the aim of expanding stored compressed air as far as possible to atmospheric pressure in order to prevent the strong cooling or freezing avoid and recover as much energy as possible. In all figures of the present application, all liquid connections or oil connections that are welded or otherwise fastened to the hollow cylinders or that are routed through channels in the central part are provided with non-return valves, so that the desired required liquid flow or oil flow can always be achieved without electrically or pneumatically controlled valves. oil flow is reached. If a chamber is sucked full, the valve to the motor / consumer closes due to the resulting vacuum and at the same time the valve to the liquid tank / liquid reservoir or oil tank / oil reservoir opens. Conversely, the opposite chamber is emptied / pressed out to the motor / consumer, whereby the resulting overpressure opens the corresponding valve and at the same time the valve to the liquid tank / liquid reservoir or oil tank / oil reservoir closes. Basically, this system works like a heart, with the check valves being the heart valves.

The basic structure of the compressed gas energy conversion device according to the invention includes as a preliminary stage a compressed gas energy conversion heat exchanger device according to the invention, which supplies the main unit, i.e. the compressed gas energy conversion heat exchanger device according to the invention, with the compressed air precisely matched to pressure and quantity. A compressed gas energy conversion device 50 is optimally connected upstream of this whole, although the latter is not absolutely necessary. The compressed air is adjusted as precisely as possible to the desired pressure in the compressed gas energy conversion device 50 or, if necessary, readjusted in the compressed gas energy conversion heat exchanger device by the piston rod or a piston being equipped with a displacement measuring system that allows, after a previously calculated distance, which the pistons have traveled to close the respective gas inlet valve in order to use the expansion of the compressed air.

In the embodiment of the compressed gas energy conversion device of FIG 14 the first exemplary embodiment of the compressed gas energy conversion heat exchanger device preliminary device 137 is used, which has already been described above with reference to FIG 12 had been described. This first exemplary embodiment of the compressed gas energy conversion heat exchanger device preliminary device 137 consists of the first hollow cylinder 106 which is divided into two equal halves by the central part 112 . The piston rod 109, on the ends of which the first piston 110 and the second piston 111 are mounted, leads through this central part 112. This creates four chambers. Between the first end wall 107 and the first piston 110, the first chamber 113 for air. Between the first piston 110 and the middle part 112 the second chamber 115 for oil. Between the middle part 112 and the second piston 111 the fourth chamber 116 for oil and between the second piston 111 and the second end wall 108 the third chamber 114 for air.

In order to improve the heat exchange function, the piston rod 109 of the compressed gas energy conversion heat exchanger device preliminary device can be designed as a piston tube 123 or can be replaced with the piston tube 123, if necessary. The second hollow cylinder 124 is guided through this piston tube 123 and through the first end wall 107 and the second end wall 108 and the middle part 112, through which oil can then be sucked and thus the first chamber 113 and the third chamber 114, in which there is air , also be "heated" from the inside (cf. the in 13 shown second embodiment of the compressed gas energy conversion heat exchanger device preliminary device 138).

In the further description, however, for the sake of simplicity, it is generally assumed that the oil is sucked in via the first liquid connection device 121 and the second liquid connection device 122, without the special possibility of sucking in the oil via the second liquid line 126, the second hollow cylinder 124 and the first Liquid line 125 to mention.

In the ideal case, compressed air from the compressed air reservoir is now adjusted to the desired pressure via the compressed gas energy conversion device 50 and is thus fed to the compressed gas energy conversion heat exchanger device, e.g. via the first gas connection device 117. The first chamber 113 is filled with compressed air, and the first piston 110, the piston rod 109 and the second piston 111 pressed down. The second gas connection device 118 is open to the second gas line 78.

Meanwhile, the third liquid connection device 119, from which an oil pressure line leads to an oil motor, is open. The fourth liquid connection device 120 is closed. The first liquid connection device 121 is closed and the second liquid connection device 122 is opened for the purpose of sucking in oil.

The compressed air supply to the second gas connection device 118 is of course closed. When the second piston 111 has reached the second end wall 108, the compressed air supply to the first gas connection device 117 closes at this point at the latest, and a connecting line opens from the first gas connection device 117 to the first gas line 77.

The compressed gas energy conversion heat exchanger device 60 now begins to operate as described above with reference to FIG 11 was described. If this working cycle described has been carried out, the connection of the second gas connection device 118 to the second gas line 78 is now closed and the second gas connection device 118 is pressurized. The second piston 111 and the first piston 110 are now correspondingly pushed upwards until the first piston 110 has reached the first end wall 107 .

In this case, the third liquid connection device 119 is closed to the oil motor. The fourth liquid connection device 120 is open and connected to the oil motor via a pressure line. The first liquid connection device 121 is open for suction of oil, and the second liquid connection device 122 is closed.

The compressed air supply to the second gas connection device 118 is now closed and the connection to the second gas line 78 is opened. The rest of the process is then as above with reference to 11 described.

Of course, it is not absolutely necessary to interrupt the supply of compressed air when the first piston 110 and the second piston 111 reach their top or bottom dead centers. In particular when the available pressures are low, it can make sense to maintain the supply of compressed air until the compressed gas energy conversion heat exchanger device has also completed the desired work cycle in whole or in part.

The combination of the compressed gas energy conversion heat exchanger device according to the invention and the compressed gas energy conversion heat exchanger device according to the invention as a group of two results in an exemplary embodiment of a compressed gas energy conversion device according to the invention. The combination of these two units, i.e. the compressed gas energy conversion heat exchanger device according to the invention and the compressed gas energy conversion heat exchanger device according to the invention, and the associated valves is now referred to below as the "unit". It is possible to use the compressed gas energy conversion heat exchanger device according to the invention or the compressed gas energy conversion heat exchanger device according to the invention individually or jointly or to connect an infinite number of units in series or in parallel.

In particular with reference to 15 and with simultaneous recourse to 14 such a compressed gas energy conversion device will now be described as a further possible exemplary embodiment of the compressed gas energy conversion device, in which two units are connected to one another.

It is assumed that both the first piston 110 and the second piston 111 are initially at top dead center in both units in the compressed gas energy conversion heat exchanger device preliminary stage device. In the respective compressed gas energy conversion heat exchanger device of the two units, the first piston 69 and the second piston 70 are each at bottom dead center.

All valves on both units are closed. The first compressed gas supply line 100 and the second compressed gas supply line 101 are pressurized with gas, e.g. from a storage tank via a pressure reducer or from a compressed gas energy conversion device 50.

Air, for example, can be used as the gas. But it is also just as possible that instead of or together with air, any other gas, for example biogas and/or methane and/or any hydrocarbon gas and/or a mixture of hydrocarbon gases and/or a mixture of air and one or more Hydrocarbon gases can be used.

Stroke 1 opens a first valve 128 on a first quad valve block 127 of the first unit and pressurized gas then flows through a fifth gas line 144 into the first chamber 113 of the compressed gas energy conversion heat exchanger means pre-stage means. The first piston 110 of the compressed gas energy conversion heat exchanger device pre-stage device and the second piston 111 of the compressed gas energy conversion heat exchanger device pre-stage device are pushed to the bottom dead center. In the process, oil is pressed from the second chamber 115 of the compressed gas energy conversion heat exchanger device preliminary stage device via the third liquid connection device 119, from which an oil pressure line leads to the oil motor, to the oil motor.

In this case, the first fluid connection device 121 is closed. The second liquid connection device 122 is open, and the fourth chamber 116 of the compressed gas energy conversion heat exchanger device preliminary stage device sucks up oil via the second liquid connection device 122 .

A fifth valve 133 supply line is closed on a second four-way valve block 132 . A sixth valve 134, a seventh valve 135 and an eighth valve 136 are each opened.

If the first chamber 113 of the compressed gas energy conversion heat exchanger device preliminary device is completely filled with gas, the first valve 128 closes and interrupts the supply of compressed air via the first compressed gas supply line 100.

Now bar 2 begins on the first unit, and at the same time bar 1 begins on the second unit. The second valve 129 opens, the compressed gas from the first chamber 113 of the compressed gas energy conversion device heat exchanger preliminary device flows via the fifth gas line 144 and the sixth gas line 139 and the first gas line 77 into the fifth chamber 75 of the compressed gas energy conversion device heat exchanger device. The first piston 69 of the compressed gas energy conversion heat exchanger device and the second piston 70 of the compressed gas energy conversion heat exchanger device are pushed to the top dead center. In the process, oil is pressed out of the fourth chamber 74 of the compressed gas energy conversion heat exchanger device via the sixth liquid line 95 to the oil motor. The second liquid line 96 is closed and the fifth liquid line 94 to the oil motor is also closed. The third liquid line 97 is open for sucking in oil, so that the third chamber 73 of the compressed gas energy conversion heat exchanger device is sucked full of oil via the third liquid line 97 . The fifth liquid line 94 to the oil motor is closed. At the point in time mentioned at the beginning of this paragraph, i.e. at the beginning of cycle 2 on the first unit and the simultaneous start of cycle 1 on the second unit, it must or can be assumed that in the third chamber 114 the compressed gas energy conversion heat exchanger means pre-stage means of the second unit and air is present in the sixth chamber 76 of the compressed gas energy conversion heat exchange means of the second unit after partial expansion. This air is supplied to the second chamber 72 of the compressed gas energy conversion heat exchanger device of the first unit via a seventh gas line 145 and the second gas connection device 99 . The fifth valve 133 on the second four-way valve block 132 of the second unit is closed, the sixth valve 134 is open, the seventh valve 135 is open and the eighth valve 136 is closed.

Now bar 3 begins on the first unit, and at the same time bar 2 begins on the second unit. On the second four-valve block 132 of the first unit, the fifth valve 133 opens and compressed gas then flows through the eighth gas line 143 into the third chamber 114 of the compressed gas energy conversion heat exchanger device preliminary device. The sixth valve 134 is closed.

The seventh valve 135 and the eighth valve 136 are open so that the sixth chamber 76 of the compressed gas energy conversion heat exchanger device of the first unit and the first chamber 71 of the compressed gas energy conversion heat exchanger device of the second unit can vent or their air to another consumer can be supplied. The second piston 111 of the compressed gas energy conversion heat exchanger device pre-stage device and the first piston 110 of the compressed gas energy conversion heat exchanger device pre-stage device are pushed to the top dead center. In the process, oil is pressed out of the fourth chamber 116 of the compressed gas energy conversion heat exchanger device preliminary stage device via the fourth liquid connection device 120 and an oil pressure line connected thereto to the oil motor.

The first liquid connection device 121 is open, so that the second chamber 115 of the compressed gas energy conversion heat exchanger device preliminary stage device can soak up oil via the first liquid connection device 121 . The third liquid connection device 119 and the second liquid connection device 122 are closed.

At the beginning of cycle 2 of the second unit, the third valve 130 opens in the first four valve block 127 of the first unit, and the still pressurized gas from the fifth chamber 75 of the compressed gas energy conversion heat exchanger device as well as that now by the upward movement of the first Piston 110 of the compressed gas energy conversion heat exchanger device preliminary stage device and the second piston 111 of the compressed gas energy conversion heat exchanger device preliminary stage device - triggered by cycle 3 - gas displaced from the first chamber 113 of the compressed gas energy conversion heat exchanger device preliminary stage device of the first unit now flows via a ninth gas line 142 to the second gas connection device 99 into the second chamber 72 of the compressed gas energy conversion heat exchanger device and there supports the movement of the first piston 69 of the compressed gas energy conversion heat exchanger device and of the second piston 70 of the compressed gas energy conversion heat exchanger device to top dead center during bar 2 of the second unit. If the compressed gas energy conversion heat exchanger device preliminary stage device of the first unit has completed cycle 3 with the reaching of the top dead center of the first piston 110 of the compressed gas energy conversion heat exchanger device preliminary stage device and of the second piston 111 of the compressed gas energy conversion heat exchanger device preliminary stage device, then begins at the first unit bar 4 and the second unit bar 3.

In the first unit, the sixth valve 134 opens on the second quadruple valve block 132, and the compressed gas from the third chamber 114 of the compressed gas energy conversion heat exchanger device preliminary device flows via a tenth gas line 140 and the second gas line 78 into the sixth chamber 76 of the compressed gas energy conversion device. heat exchanger device. The first piston 69 of the compressed gas energy conversion heat exchanger device and the second piston 70 of the compressed gas energy conversion heat exchanger device are pushed to the bottom dead center. In the process, oil is pressed out of the third chamber 73 of the compressed gas energy conversion heat exchanger device via the fifth liquid line 94 to the oil motor.

The third liquid line 97 is closed. The sixth liquid line 95 to the oil motor is also closed.

The second liquid line 96 is open, so that the fourth chamber 74 of the compressed gas energy conversion heat exchanger device can soak up oil via this second liquid line 96 .

At the beginning of cycle 4 of the first unit and cycle 3 of the second unit, the fourth valve 131 opens in the first four-way valve block 127 of the first unit, and the residual compressed gas from the fifth chamber 75 of the compressed gas energy conversion heat exchanger device of the first unit and the second Compressed gas energy conversion heat exchanger means chamber 72 of the second unit may be vented to atmosphere or fed to another consumer.

Now the first unit begins again with cycle 1, and the second unit begins with cycle 4. The seventh valve 135 is opened in the second four-way valve block 132 of the first unit, and via an eleventh gas line 141 and the first gas connection device 98 the first Chamber 71 of the compressed gas energy conversion heat exchanger device of the second unit, the partially expanded compressed gas from the third chamber 114 of the compressed gas energy conversion heat exchanger device preliminary device and the sixth chamber 76 of the compressed gas energy conversion heat exchanger device of the first unit and supports the movement of the first piston 69 of the compressed gas energy conversion heat exchanger device and the second piston 70 of the compressed gas energy conversion heat exchanger device of the second unit in the direction of the bottom dead center during cycle 4. If cycle 4 of the second unit has ended, the second four-way valve block 132 of the first unit opens eighth v valve 136 and releases the residual pressurized gas into the atmosphere or feeds it to the next consumer.

This process described in the previous paragraphs regarding the functioning of the compressed gas energy conversion device is now repeated constantly. The arrival of the pistons at the end points can be determined with a path measuring system, e.g. on the piston rods in the middle parts or with contact switches in the end walls or with non-contact buttons. These switches trigger the next valve switching.

The number of units can be expanded as desired and thus the scope of the compressed gas energy conversion device according to the invention can be increased as desired.

In the above-described exemplary embodiments of the compressed gas energy conversion device with only one group of two or with two groups of two or only one unit or two units, there is always an internal dynamic pressure that does not lead to any loss of performance as long as the "exhaust air" is supplied with further work, e.g Turbine. However, if the "exhaust air" is only to be used thermally (removal of heat), it is advisable to to connect three, four, five or six units or groups of two in a row in order to gain time and ensure that the "exhaust air" is blown off before the next work cycle begins. If the oil motors, which are driven by the individual compressed gas energy conversion heat exchanger devices and by the individual compressed gas energy conversion heat exchanger device preliminary devices, are connected to one another by means of a continuous shaft, and if the intake quantities of the oil motors correspond to the displaced oil quantities of the individual compressed gas energy conversion heat exchanger Devices and the individual compressed gas energy conversion heat exchanger device preliminary devices are compatible, the processes or clocks of the individual units will always run smoothly and harmoniously, and the oil motors then act like a flow divider.
