Description

The present invention relates in the broadest sense 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 statements should be made in advance of the following: If the term "gas" is used in the text of the present description of the invention and the claims, this term currently primarily means the gas "air" for purely practical economic reasons, but is From a purely physical-technical point of view, the present invention is in no way restricted to the use of air as the gas used. Rather, from a purely physical-technical point of view, any gas, for example so-called “biogas”, can be used for carrying out 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 therefore by no means restricted to the gas air alone, although at least currently the use of the gas air is by far the predominant advantage over the physical and practical reasons for purely current economic reasons. Technically easily possible - and under certain conditions also economically very sensible - use of other gases, such as any hydrocarbon gases, is given.

Gas compressed to above atmospheric pressure and in particular air compressed above atmospheric pressure, which is often simply referred to as “compressed air”, has been very important for well over a hundred years and has a wide variety of practical applications in industrial technology. Compressed air has also been used as an energy store and drive means for well over a hundred years, for example in compressed air-powered locomotives on mine railways. With the currently advancing so-called "energy turnaround" and the associated increasing 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 growing ever greater, with the help of which one can temporarily excess wind turbines and solar energy systems Energy provided and not immediately usable by electrical energy end consumers can be stored and retrieved later when required, ie when the wind turbines and solar energy systems are just producing too little 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 bottles or compressed air tanks by means of an air compressor. To put it quite simply, this compressed air, which can be stored and stored for any length of time, can then later be released again at any time and serve as a drive means for driving an electrical energy generator. Such devices referred to as “compressed air energy storage systems” are, for example, already in the DE 10 2013 105 186 A1 or in the US 2012/0210705 A1 described.

For compressing air or, more generally, for compressing gas, conventional electrically driven solid-state mechanical screw compressors and conventional electrically driven solid-state mechanical piston compressors have been known and millions of times in use worldwide. In addition, in the prior art there are also different and somewhat unconventional hydraulic air compression devices with double-acting cylinders in which a piston slides back and forth and in which one cylinder chamber is filled with air, while the other cylinder chamber is filled with high pressure by means of an electrically driven one Pump oil is 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 the DE 10 2013 105 186 A1 described as part of the compressed air energy storage system presented in this publication. The latter, from the DE 10 2013 105 186 A1 Known hydraulic air compression device preferably runs very slowly, but the heat generated during air compression, which actually represents a loss of efficiency as such, can be absorbed very well and stored, for example, in the form of heated water. However, the in the DE 10 2013 105 186 A1 described hydraulic air compression device is still a conventional electrically driven solid-state mechanical air compressor, such as an electrically driven solid-state mechanical screw compressor or an electrically driven solid-state mechanical piston compressor, useful as a prefiller and for a really efficient operation of the DE 10 2013 105 186 A1 hydraulic air compression device described even absolutely necessary.

Quite generally and completely independent of those described above 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 run as long as possible for optimal operation and should be switched off and on again as little as possible. On the other hand, a conventional electrically driven solid-state mechanical piston compressor must not regularly be expected to operate significantly more than fifteen minutes without a cooling break.

Such operational restrictions are subject to the DE 10 2013 105 186 A1 Although not described hydraulic air compression device, ie it can both easily withstand continuous operation and an operating mode in which it is switched on and off several times in a row within very short time intervals, but works in the DE 10 2013 105 186 A1 The hydraulic air compression device described above is preferred only very slowly, which is on the one hand an advantage for heat storage, as already indicated above, but on the other hand this is definitely with regard to some time-critical applications, for example with regard to the often time-critical application in an air pressure energy storage system for the power grid -Buffer storage of energy from solar power plants and wind turbines, can be disadvantageous.

The conversion of the energy stored in the form of compressed air into electrical energy is identical to that in the DE 10 2013 105 186 A1 The compressed air energy storage system described is basically possible without further ado, but this has in the DE 10 2013 105 186 A1 described compressed air energy storage system has a serious disadvantage. This compressed air energy storage system requires too much solid material for the piston - seen in relation to the working capacity of the compressed air used in it. 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 too sluggish.

The object of the invention is to provide a new type of hydraulic piston device which can be used at least for the purpose of gas compression and which, in general speaking, then works as a hydraulic gas compression device according to the principle of the "double-acting cylinder" mentioned in the previous paragraph , but is designed in a special way so that it makes pre-filling of gas by means of an electrically driven solid-state mechanical screw compressor or by means of an electrically driven solid-state mechanical piston compressor superfluous, requires as little energy as possible, i.e. works more efficiently than previous such gas compression systems or air compression systems, without Problems can work both in continuous operation and in intermittent operation and is less sluggish than that in the DE 10 2013 105 186 A1 hydraulic air compression device described. A further object of the invention is to provide a new type of compressed gas energy conversion device in which the new type of hydraulic piston device mentioned in the previous sentence is used as an essential component. In addition, the invention is based on the object of providing a novel compressed gas energy conversion heat exchanger device which is suitable as a basis for building a compressed gas energy conversion device which does not work as sluggishly as that in FIG DE 10 2013 105 186 A1 described compressed air energy storage system. In addition, the invention is based on the object of providing a novel compressed gas energy conversion heat exchanger device precursor device which is suitable both for operational interconnection with the above-mentioned novel compressed gas energy conversion heat exchanger device according to the invention as its precursor, and - if desired - autonomously, ie can also be operated for energy conversion purposes, but without a downstream compressed gas energy conversion heat exchanger device. Finally, the invention is also based on the object of providing a novel compressed gas energy conversion device in which the aforementioned novel compressed gas energy conversion heat exchanger device and the aforementioned novel compressed gas energy conversion heat exchanger preliminary stage device are used.

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

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

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

Now, by means of a pump, more oil is drawn from the oil tank via the third fluid connection device 29 into the fifth chamber 23 pumped in. Because of the incompressibility of the oil, this leads to the fact that, starting from the in the 1 to 4th The assumed starting position shown is the piston rod 14th with the first piston 15th , the second piston 16 , the third piston 17th and the fourth piston 18th moved to the right. Correspondingly, the oil from the fourth chamber is released at the same time 22nd via the second liquid connection device 28 conveyed out into the oil tank. The one in the sixth chamber 24 any air is via the twelfth gas connection device 46 from the sixth chamber 24 pressed out and fed to the compressed air storage device. The air from the second chamber 20th and the air from the eighth chamber 26th is via the third gas line 43 or via the fourth gas line 44 through the tenth gas connection device 42 through into the third chamber 21 pressed and there forms an excess air pressure. The latter happens even when the volume of the third chamber is enlarged 21 because there are two chambers - namely the second chamber 20th and the eighth chamber 26th - in only one - namely the third chamber 21 - work into it. The excess air pressure in the third chamber 21 accordingly helps the air out of the sixth chamber 24 through the twelfth gas connection device 46 to squeeze out and also the oil from the fourth chamber 22nd through the second fluid connection device 28 to squeeze out. The piston stroke is the piston rod 14th tuned so that the movement of the piston rod 14th in the picture of 1 to 4th to the right continues until both the second chamber 20th as well as the fourth chamber 22nd as well as the sixth chamber 24 as well as the eighth chamber 26th each have a volume of almost zero. Meanwhile, the first chamber has 19th via the first gas connection device 31 Air sucked in, and the seventh chamber 25th has over the third gas connection device 33 Air sucked in. Accordingly, at the end of the movement of the piston rod 14th in the picture of 1 to 4th to the right both the first chamber 19th as well as the third chamber 21 as well as the fifth chamber 23 as well as the seventh chamber 25th assumed their maximum possible volume. This is then both in the first chamber 19th as well as in the seventh chamber 25th Air under atmospheric pressure. In the third chamber 21 there is air with a pressure above atmospheric pressure, i.e. compressed air, and the fifth chamber 23 contains oil.

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

Now oil is drawn from the oil tank via the first liquid connection device by means of the pump 27 into the fourth chamber 22nd pumped in. Because of the incompressibility of the oil, this leads to the 1 to 4th the piston rod 14th with the first piston 15th , the second piston 16 , the third piston 17th and the fourth piston 18th now moved to the left. Correspondingly, the oil from the fifth chamber is released at the same time 23 via the fourth fluid connection device 30th conveyed out into the oil tank. The one in the third chamber 21 Any air is via the eleventh gas connection device 45 from the third chamber 21 pressed out and fed to the compressed air storage device. The air from the first chamber 19th and the air from the seventh chamber 25th is via the first gas line 36 or via the second gas line 37 through the fifth gas connection device 35 through into the sixth chamber 24 pressed and there forms an excess air pressure. The latter happens even when the volume of the sixth chamber is enlarged 24 because there are two chambers - namely the first chamber 19th and the seventh chamber 25th - in only one - namely the sixth chamber 24 - work into it. The excess air pressure in the sixth chamber 24 accordingly helps the air out of the third chamber 21 through the eleventh gas connection device 45 to squeeze out and also the oil from the fifth chamber 23 through the fourth fluid connection device 30th to squeeze out. The piston stroke is the piston rod 14th tuned so that the movement of the piston rod 14th in the picture of 1 to 4th to the left continues until both the first chamber 19th as well as the third chamber 21 as well as the fifth chamber 23 as well as the seventh chamber 25th each have a volume of almost zero. Meanwhile the second chamber has 20th via the sixth gas connection device 38 Air sucked in, and the eighth chamber 26th has about the eighth gas connection device 40 Air sucked in. Accordingly, at the end of the movement of the piston rod 14th in the picture of 1 to 4th to the left both the second chamber 20th as well as the fourth chamber 22nd as well as the sixth chamber 24 as well as the eighth chamber 26th assumed their maximum possible volume. This is then both in the second chamber 20th as well as in the eighth chamber 26th Air under atmospheric pressure. In the sixth chamber 24 there is air with a pressure above atmospheric pressure, therefore compressed air, and the fourth chamber 22nd contains oil.

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

Now oil is drawn from the oil tank via the third fluid connection device by means of the pump 29 into the fifth chamber 23 pumped in. Because of the incompressibility of the oil, this leads to the 1 to 4th the piston rod 14th with the first piston 15th , the second piston 16 , the third piston 17th and the fourth piston 18th now moved to the right again. Correspondingly, the oil from the fourth chamber is released at the same time 22nd via the second liquid connection device 28 conveyed out into the oil tank. The one in the sixth chamber 24 any air is via the twelfth gas connection device 46 from the sixth chamber 24 pressed out and fed to the compressed air storage device. The air from the second chamber 20th and the air from the eighth chamber 26th is via the third gas line 43 or via the fourth gas line 44 through the tenth gas connection device 42 through into the third chamber 21 pressed and there forms an excess air pressure. The latter happens even when the volume of the third chamber is enlarged 21 this is because two chambers - namely the second chamber 20th and the eighth chamber 26th - in only one - namely the third chamber 21 - work into it. The excess air pressure in the third chamber 21 accordingly helps the air out of the sixth chamber 24 through the twelfth gas connection device 46 to squeeze out and also the oil from the fourth chamber 22nd through the second fluid connection device 28 to squeeze out. The piston stroke is the piston rod 14th tuned so that the movement of the piston rod 14th in the picture of 1 to 4th to the right continues until both the second chamber 20th as well as the fourth chamber 22nd as well as the sixth chamber 24 as well as the eighth chamber 26th each have a volume of almost zero. Meanwhile, the first chamber has 19th via the first gas connection device 31 Air sucked in, and the seventh chamber 25th has over the third gas connection device 33 Air sucked in. Accordingly, at the end of the movement of the piston rod 14th in the picture of 1 to 4th to the right both the first chamber 19th as well as the third chamber 21 as well as the fifth chamber 23 as well as the seventh chamber 25th assumed their maximum possible volume. This is then both in the first chamber 19th as well as in the seventh chamber 25th Air under atmospheric pressure. In the third chamber 21 there is air with a pressure above atmospheric pressure, i.e. compressed air, and the fifth chamber 23 contains oil.

After completing the just described stroke of the piston rod 14th in the picture of 1 to 4th the valve devices are then moved to the right in preparation for the renewed stroke of the piston rod 14th switched to the left as it was above before the description of the stroke of the piston rod 14th has been explained to the left. This is how the piston rod moves 14th with the first piston 15th , the second piston 16 , the third piston 17th and the fourth piston 18th back and forth, and alternately at the eleventh gas connection device 45 or at the twelfth gas connection device 46 Compressed air provided, which either - as described above - can be fed to a compressed air storage device, which, however, can also instead be fed to any compressed air consumer, for example a blower device or a pneumatic hammer device. In other exemplary embodiments of the hydraulic piston device according to the invention 1 also be provided, the eleventh gas connection device 45 and the twelfth gas connection device 46 to be provided with such valve devices that a user can optionally decide operationally whether the straight from the respective eleventh or twelfth gas connection device 45 , 46 exiting compressed air is either introduced into a compressed air storage device or compressed air is supplied to a consumer.

6th shows schematically and not to scale a second embodiment of the hydraulic piston device according to the invention 1 . This second embodiment of the hydraulic piston device according to the invention 1 works in principle exactly like the one above with reference to the 1 to 4th described first embodiment of the hydraulic piston device according to the invention 1 , but differs from this in the arrangement and the proportions of the four hollow cylinders 2 , 5 , 8th , 11 which results in improved operational properties.

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

The in 6th illustrated second embodiment of the hydraulic piston device according to the invention 1 all have four hollow cylinders 2 , 5 , 8th , 11 each the same length. The second hollow cylinder 5 and the third hollow cylinder 8th 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 . The diameter of the first hollow cylinder is particularly preferred 2 to make at least twice as large as the diameter of the second hollow cylinder 5 . Of course, the size of the first piston must also correspond accordingly 15th and the size of the fourth piston 18th must be adjusted to ensure that these are still closely attached to the inner wall of the first hollow cylinder 2 or the fourth hollow cylinder 11 snugly and furthermore a pneumatically tight separation of the first chamber 19th from the second chamber 20th or the seventh chamber 25th from the eighth chamber 26th guarantee. The advantage of such in 6th construction shown compared to that in 1 to 4th The construction shown for the generation of compressed air consists in that in the second exemplary embodiment of the piston device according to the invention 1 when the piston rod moves 14th to the right the second chamber 20th with a large volume and the eighth chamber 26th with a large volume in the third chamber 21 , which has a much smaller volume, act into it, so that a significantly higher air overpressure in the third chamber 21 can be achieved than in the first embodiment of the piston device according to the invention 1 . The same applies to the movement of the piston rod 14th to the left: In the second exemplary embodiment of the piston device according to the invention 1 act when the piston rod moves 14th to the left the first chamber 19th with a large volume and the seventh chamber 25th with a large volume in the sixth chamber 24 , which has a much smaller volume, into it, so that a significantly higher air overpressure in the sixth chamber 24 can be achieved than in the first embodiment of the piston device according to the invention 1 .

In very general terms, the proportions of the four hollow cylinders are given 2 , 5 , 8th , 11 to each other always in relation to the gas pressure or air pressure that can be achieved in the end with gas or air compression.

This in 6th illustrated second embodiment of the hydraulic piston device according to the invention 1 is also set up so that the first hollow cylinder 2 and the second hollow cylinder 5 sit directly next to each other so that the second end wall 4th and the third end wall 6th at least partially coincide. The third hollow cylinder is also located 8th and the fourth hollow cylinder 11 directly to each other, so that the sixth end wall 10 and the seventh end wall 12th at least partially coincide. In terms of sealing technology, such a structure offers significant advantages over that in the 1 to 4th shown structure of the first embodiment of the hydraulic piston device according to the invention 1 , in which all four hollow cylinders 2 , 5 , 8th , 11 are arranged completely separately from each other and accordingly a higher sealing-technical effort has to be made.

In a further exemplary embodiment, not shown in the figures, of the hydraulic piston device according to the invention 1 it is provided that the diameter of the piston rod 14th over the length of the piston rod 14th varies across such that the piston rod 14th immediately following the first piston 15th towards the second piston 16 has a larger diameter than immediately following the second piston 16 towards the first piston 15th and that also the piston rod 14th immediately following the fourth piston 18th towards the third piston 17th has a larger diameter than immediately following the third piston 17th towards the fourth piston 18th down. Such a constructive measure provides an even further improved support for gas or air compression.

It is true that the individual special exemplary embodiments of the hydraulic piston device according to the invention, which are described in more detail here, have been described above 1 explained above all with reference to the use or compression of the gas air, but it should be emphasized at this point 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 in the hydraulic piston device according to the invention 1 can be used and condensed by them.

The same applies to the naming of oil as in the hydraulic piston device according to the invention 1 liquid to be used. It is true that, for purely practical economic reasons, oil is often used as a liquid in the hydraulic piston device according to the invention 1 used, but the operation of the hydraulic piston device according to the invention 1 in principle easily possible with any other liquid, for example with water.

As in the case of the hydraulic piston device according to the invention described in detail above 1 can accordingly of course also with the compressed gas energy conversion device according to the invention 50 air, for example, can be used as the gas. But it is also with the compressed gas energy conversion device according to the invention 50 just as well 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 in the invention hydraulic piston device 1 can be used.

The same applies to the compressed gas energy conversion device according to the invention 50 liquid to be used. For purely practical economic reasons, oil is often used as the liquid in the compressed gas energy conversion device according to the invention 50 used, but the operation of the compressed gas energy conversion device according to the invention 50 in principle easily possible with any other liquid, for example with water.

Both described above from a purely constructive point of view Embodiments of the compressed gas energy conversion device according to the invention 50 work like this:

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

The one to the first gas connection device 31 associated valve device that belongs to the second gas connection device 32 associated valve device that belongs to the third gas connection device 33 associated valve device that belongs to the fourth gas connection device 34 valve device belonging to the sixth gas connection device 38 associated valve device that belongs to the seventh gas connection device 39 valve device belonging to the eighth gas connection device 40 associated valve device and the ninth gas connection device 41 belonging valve device are open and remain - at least for the purposes of the following functional description of the two in the 5 or. 7th Embodiments shown 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. 7th Embodiments shown of the compressed gas energy conversion device 50 can still readily be seen, the first chamber 19th , the second chamber 20th , the seventh chamber 25th and the eighth chamber 26th For example, they can simply be used to collect relaxing and consequently cooling compressed air from the compressed air storage device and to pass cold air to a consumer, or they can - when the compressed gas energy conversion device according to the invention is in operation 50 in a warm environment or in a warm partial environment - can be used to simply suck in warm outside air and pass it through to a consumer of warm air. The possibilities mentioned in the previous paragraph are, however, only possible side effects that - if desired - when operating the compressed gas energy conversion device according to the invention 50 can be exploited with, but do not necessarily have to be exploited.

Absolutely essential for the operation of the compressed gas energy conversion device according to the invention 50 are, however, the second hollow cylinder 5 with the third chamber 21 and the fourth chamber 22nd as well as the third hollow cylinder 8th with the fifth chamber 23 and the sixth chamber 24 .

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

The one for the fifth gas connection device 35 The associated valve device is initially open. Also for the eleventh gas connection device 45 The associated valve device is initially open. Accordingly, compressed air is drawn from the compressed air storage device through the eleventh gas connection device 45 into the third chamber 21 initiated, which causes the piston rod 14th with the four pistons fixed on it 15th , 16 , 17th , 18th in the views of the 5 or. 7th moved to the right. Accordingly, the sixth chamber becomes air 24 through the fifth gas connection device 35 pushed out and through the seventh gas line 55 the consumer device 59 , which uses the air thermally and / or mechanically and / or chemically, supplied. The consumer device just mentioned 59 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 according to the invention to be described further below 60 , 146 or, for example, an exemplary embodiment of a pressurized gas energy conversion heat exchanger device upstream device according to the invention to be described further below 137 , 138 , 149 or, for example, an exemplary embodiment of a compressed gas energy conversion device according to the invention to be described further below. At the same time there is the one from the sixth chamber 24 forced out air through the eighth gas line 57 on the air side of the second pressure control valve device 56 which air pressure and oil pressure regulate against each other.

During the just mentioned movement of the piston rod 14th with the four pistons fixed on it 15th , 16 , 17th , 18th in the views of the 5 or. 7th to the right there is also oil from the fourth chamber 22nd pressed out and reaches the first liquid connection device 27 and the first liquid line 47 to a machine to be driven by flowing oil 48 which can be, for example, a turbine driving an electric generator. In doing so, the oil flow is through the first liquid line 47 via the second pressure control valve device 56 , which regulates air pressure and oil pressure against each other, controlled, because the first fluid connection device 27 communicates through the first liquid line 47 , the fourth liquid line branching off from it 58 and the second pressure regulating valve device 56 , which regulates air pressure and oil pressure against each other, with the fifth gas connection device 35 .

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

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

The valve devices are now switched over as follows: The one for the eleventh gas connection device 45 The associated valve device is closed. The one for the tenth gas connection device 42 The associated valve device is opened. The one to the fifth gas connection device 35 belonging valve device 35 will be closed. The valve device belonging to the twelfth gas connection device 46 will be opened. The one to the fourth fluid connection device 30th The associated valve device is closed. The one to the second fluid connection device 28 The associated valve device is opened. The one to the first fluid connection device 27 The associated valve device is closed. The one to the third fluid connection device 29 The associated valve device is opened.

Accordingly, compressed air is now from the compressed air storage device through the twelfth gas connection device 46 into the sixth chamber 24 initiated, which causes the piston rod 14th with the four pistons fixed on it 15th , 16 , 17th , 18th in the views of the 5 or. 7th moved to the left. Accordingly, air is released from the third chamber 21 through the tenth gas connection device 42 pushed out and over the fifth gas line 51 the consumer device 59 , which uses the air thermally and / or mechanically and / or chemically, supplied. At the same time the one from the third chamber is standing 21 forced out air through the sixth gas line 53 on the air side of the first pressure control valve device 52 which air pressure and oil pressure regulate against each other.

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

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

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

The valve devices are now switched back to their respective starting positions, namely as follows: The one for the eleventh gas connection device 45 The associated valve device is opened. The one for the tenth gas connection device 42 The associated valve device is closed. The one to the fifth gas connection device 35 The associated valve device is opened. The valve device belonging to the twelfth gas connection device 46 will be closed. The one to the fourth fluid connection device 30th The associated valve device is opened. The one to the second fluid connection device 28 The associated valve device is closed. The one to the first fluid connection device 27 The associated valve device is opened. The one to the third fluid connection device 29 The associated valve device is closed.

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

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

That in the 8th , 9 and 10 Shown embodiment of the compressed gas energy conversion heat exchanger device 60 works like this:

• It is assumed for the present exemplary embodiment that the compressed gas energy conversion heat exchanger device 60 is mounted vertically, the fifth liquid line 81 So starting from the sixth hollow cylinder 66 extends upwards and the eighth hollow cylinder 68 - screwed to the fifth piston at the top 69 and screwed to the sixth piston at the bottom 70 - is at the bottom dead center. The fifth piston is located here 69 on the first middle part 64 and on the second middle part 65 on, and the sixth piston 70 lies on the tenth front wall 63 at. The sixth liquid line 82 is on her of the seventh hollow cylinder 67 remote end to one in the 8th , 9 and 10 not shown connected oil tank. The one to the tenth liquid line 97 The associated valve device is open and therefore allows for a stroke of the fifth piston 69 upwards a suction of oil from the oil tank into the thirteenth chamber 75 via the sixth liquid line 82 , the seventh hollow cylinder 67 , the sixth hollow cylinder 66 and the fifth liquid line 81 . The one to the ninth liquid line 96 The associated valve device is closed, as is that of the seventh liquid line 94 The associated valve device is closed. The one to the eighth liquid line 95 The associated valve device is open.

The eighth liquid line 95 leads in the present embodiment compressed gas energy conversion heat exchanger device according to the invention 60 to a motor which is driven by the oil that is present at the stroke of the sixth piston 70 up through the eighth liquid line 95 is pushed through towards him. That through the eighth liquid line 95 Generally speaking, oil pushed through is used to perform work.

The one for the thirteenth gas connection device 98 The associated valve device is open, so when the fifth piston is lifted 69 up the one in the ninth chamber 71 air from the ninth chamber 71 via the thirteenth gas connection device 98 can escape. This then becomes the ninth chamber 71 simply vented to the outside atmosphere, or that from the ninth chamber 71 Pressed out, partially relaxed air is passed to the next consumer, the above-mentioned next consumer, for example, also again, in terms of apparatus, a compressed gas energy conversion heat exchanger device according to the invention 60 , 146 or, for example, an exemplary embodiment of a pressurized gas energy conversion heat exchanger device upstream device according to the invention to be described further below 137 , 138 , 149 or, for example, an exemplary embodiment of a compressed gas energy conversion device according to the invention to be described further below.

Also the tenth gas pipe 78 is open to the forwarding of air to the next consumer, which, as already mentioned, for example again a compressed gas energy conversion heat exchanger device according to the invention 60 , 146 or, for example, an exemplary embodiment of a pressurized gas energy conversion heat exchanger device upstream device according to the invention to be described further below 137 , 138 , 149 or, for example, an exemplary embodiment of a compressed gas energy conversion device according to the invention to be described further below.

Via the ninth gas line 77 is now compressed air from a cylinder of a preliminary stage or a similar device, for example from an embodiment of the hydraulic piston device according to the invention 1 or of an embodiment of the compressed gas energy conversion device according to the invention 50 Volume and pressure-optimized in the thirteenth chamber 75 directed. There the air expands and pushes the eighth hollow cylinder 68 with the fifth piston 69 and the sixth piston 70 up. At the same time, the fourteenth gas connection device 99 Air with the same or different pressure into the tenth chamber 72 be directed. This air acts on the sixth piston 70 and increases the force with which the eighth hollow cylinder 68 is pushed up. The twelfth chamber 74 meanwhile was filled with warm oil. During this “work cycle” with the piston stroke direction upwards, the eleventh chamber sucks 73 via the tenth liquid line 97 from the oil tank full of warm oil again. This oil is via the sixth liquid line 82 further through the seventh hollow cylinder 67 , through the second middle part 65 and through the sixth hollow cylinder 66 into the fifth liquid line 81 sucked. At the same time, the oil is drawn from the twelfth chamber 74 via the eighth liquid line 95 pressed to the consumer or to the engine driven by oil. This process continues until the fifth piston 69 the ninth front wall 62 , i.e. top dead center, is reached.

As soon as the fifth piston 69 the ninth front wall 62 , i.e. top dead center, opens the line to the ninth liquid line 96 belonging valve device, closes the tenth liquid line 97 belonging valve device, opens the one to the seventh liquid line 94 belonging valve device and closes the eighth liquid line 95 belonging valve device.

Now the “work cycle” begins with the piston stroke direction downwards, which basically runs in a mirror image of the “work cycle” described in the penultimate paragraph with the piston stroke direction upwards: Compressed air is now via the thirteenth gas connection device 98 and tenth gas line 78 fed. The ninth gas line 77 opens to the next consumer. The fourteenth gas connection device 99 vented or goes to the next consumer. Oil is now due to the downward movement of the fifth piston 69 through the seventh liquid line 94 pushed through to the oil powered motor.

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

Even with the example of 11 Air is used as gas and oil as liquid, and the relaxing air is warmed up by the warm oil to prevent icing.

Via a first compressed gas supply line 100 and the ninth gas line 77 becomes in the thirteenth chamber 75 Compressed air conducted. The amount resulting from the pressure of the compressed air introduced will be like this dimensioned so that after reaching the last expansion stage, the pressure is reached that is necessary to serve the next consumer or to ensure that the desired air temperature is reached.

The eighth hollow cylinder 68 with the sixth piston 70 and the fifth piston 69 is pushed up. In doing so, oil is drawn from the twelfth chamber 74 via the eighth liquid line 95 directed to the motor / consumer. At the same time, the eleventh chamber sucks 73 full of oil from the oil tank via the tenth liquid line 97 . The thirteenth gas connection device is here 98 from the ninth chamber 71 opened to the consumer via a first exhaust air line 104 .

A second compressed gas supply line 101 is closed, an eleventh gas line 102 is closed and a twelfth gas line 103 is opened.

Air flows out of the fourteenth chamber 76 via the tenth gas line 78 continue on the twelfth gas line 103 and the fourteenth gas connection device 99 into the tenth chamber 72 . Pressure equalization occurs in the fourteenth chamber 76 and the tenth chamber 72 . A second exhaust line 105 is closed.

Has the eighth hollow cylinder 68 with its fifth piston 69 and the sixth piston 70 reaches top dead center, then close the first compressed gas supply line 100 and the first exhaust duct 104 , and it opens the eleventh gas line 102 .

Compressed air now flows out of the thirteenth chamber 75 into the ninth chamber 71 and creates pressure equalization.

Now the twelfth gas line closes 103 and open the second exhaust duct 105 and the second compressed gas supply line 101 .

Via the second compressed gas supply line 101 and the tenth gas line 78 is now in the fourteenth chamber 76 Compressed air conducted. This leads to the eighth hollow cylinder 68 with the fifth piston 69 and the sixth piston 70 is pressed down. This is where oil is drawn from the eleventh chamber 73 via the seventh liquid line 94 directed to the motor / consumer. At the same time, the twelfth chamber sucks 74 full of oil from the oil tank via the ninth liquid line 96 .

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

16 shows a further embodiment of a compressed gas energy conversion heat exchanger device according to the invention 146 which is opposite to the above with reference to the 8th to 11 described embodiment of the compressed gas energy conversion heat exchanger device according to the invention 60 is provided with some additional components that allow some control of the operation of the compressed gas energy conversion heat exchanger device 146 enable in thermal terms. The background to this additional technical measure is that, with regard to changing ambient temperatures at the place of use of a compressed gas energy conversion heat exchanger device according to the invention and / or with regard to possibly changing operating requirements in the technical-technological environment of a compressed gas energy conversion heat exchanger device according to the invention during the Use of the compressed gas energy conversion heat exchanger device according to the invention can be useful and sometimes it may even be absolutely necessary to control the temperature of the exhaust air or the exhaust gas in a targeted manner. While it can be advantageous, for example, in the deepest winter when outside temperatures are very cold, to have as high an exhaust air temperature as possible so that the compressed gas energy conversion heat exchanger device does not partially freeze and thus perhaps even the exhaust air can be used to heat any rooms, the same high exhaust air temperature can be used in midsummer with high outside temperatures it can be useless or even counterproductive and completely undesirable. At least the risk of partial freezing of the compressed gas energy conversion heat exchanger device is lower in high summer than in deep winter, and it can therefore be more advantageous from an energetic point of view when considering the overall system in which the compressed gas energy conversion heat exchanger device is used To leave heat in the oil for further use there, while in winter it can be quite 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 liquid as a heat transfer medium. Accordingly, providing thermal control is advantageous and desirable. For this purpose, the in 16 illustrated further embodiment of the compressed gas energy conversion heat exchanger device according to the invention 146 in addition to the in 8th components already shown the following provided: a thirteenth liquid line 147 which at one end to the sixth liquid line 82 connected and arranged so that this thirteenth liquid line 147 is able to take liquid from the sixth liquid line 82 to the ninth liquid line 96 and to the tenth liquid line 97 without the liquid on its way to the ninth liquid line 96 and to the tenth liquid line 97 the seventh hollow cylinder 67 , the liquid passage device 85 and the sixth hollow cylinder 66 passes through, the connection of the thirteenth liquid line 147 to the sixth liquid line 82 with a first flow control valve device 148 is provided, which is controllable and designed such that by means of the first flow control valve device 148 can be controlled which proportion of a liquid tank via the sixth liquid line 82 at the first flow control valve device 148 incoming liquid flow into the seventh hollow cylinder 67 and what proportion in the thirteenth liquid line 147 is conducted, the control possibility of the first flow control valve device 148 this includes at least the possibility to control whether the one with her via the sixth liquid line 82 incoming liquid flow completely into the seventh hollow cylinder 67 or completely into the thirteenth liquid line 147 is directed. This is in 16 illustrated special embodiment of the compressed gas energy conversion heat exchanger device according to the invention 146 specially set up so that here the thirteenth liquid line 147 with her from the first flow control valve device 148 far end into the fifth fluid line 81 flows out.

The first flow control valve device 148 can for example have a thermostatic valve.

It is particularly preferably provided that the first flow control valve device 148 is set up so that, in addition to the control option already mentioned, the complete introduction of the with her via the sixth liquid line 82 incoming liquid flow either into the seventh hollow cylinder 67 or in the thirteenth liquid line 147 can also be controlled in such a way that it uses the sixth liquid line 82 can split incoming liquid flow, so that part of the liquid in the seventh hollow cylinder 67 and at the same time another part of the liquid enters the thirteenth liquid line 147 arrives, wherein an associated flow division ratio can be controlled continuously and / or in steps. The first flow control valve device controls 148 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 where the gas flows. A temperature measurement is preferred where the gas has already "worked", ie has already expanded.

This measurement or measurements just mentioned is / are advantageously set up, for example, in such a way that, if a gas temperature measurement is used to control the first flow control valve device 148 is made, this gas temperature measurement at least in one area of the ninth gas line 77 takes place, which of the second middle part 65 is further spaced than from the eleventh end wall 79 , and that provided a liquid temperature measurement for controlling the first flow control valve device 148 is made, this liquid temperature measurement at least either in the fifth liquid line 81 takes place or in a region of the sixth hollow cylinder 66 takes place, which of the second middle part 65 is further spaced than from the eleventh end wall 79 .

The control of the first flow control valve device 148 can for example take place 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 illustrated special embodiment of the compressed gas energy conversion heat exchanger device according to the invention 146 in thermal terms, for example, it can be done as follows: First is the first flow control valve device 148 , which can be a thermostatic valve, set so that everything on that thermostatic valve via the sixth liquid line 82 incoming oil exactly as in the embodiment of 8th permanently provided and in that embodiment, due to the technical structure provided there, no other way possible, in the seventh hollow cylinder 67 is steered and proceeded from there exactly as it is referred to above 8th was described, moved on. If by means of a measurement of the temperature of the exhaust air, which is in the area of the ninth gas line 77 takes place where the ninth gas pipe 77 the eleventh front wall 79 If it is determined that the temperature of the exhaust air is higher than necessary or permitted due to any previously defined conditions, the thermostatic valve mentioned in the previous sentence is controlled mechanically or electromechanically in such a way that it the oil supply from the sixth liquid line 82 into the seventh hollow cylinder 67 whole or for Part interrupts and instead the one from the sixth liquid line 82 incoming oil accordingly wholly or partly into the thirteenth liquid line 147 and from there then into the ninth liquid line 96 and the tenth liquid line 97 leads. To the ninth liquid line 96 and to the tenth liquid line 97 the oil as such arrives in both the embodiment of FIG 8th as well as in the embodiment of 16 always. While in the embodiment of 8th however, only a single path is permanently provided for the oil there, there is in the embodiment of FIG 16 two different routes for the oil to the ninth liquid line 96 and to the tenth liquid line 97 , whereby it can be controlled which route the oil should take or how the oil is distributed quantitatively over the two possible routes. The less oil in the seventh hollow cylinder 67 and from there via the liquid passage device 85 to the sixth hollow cylinder 66 flows, the less heat can there - in the "piston interior" - from the oil to the tenth gas line 78 and the ninth gas line 77 air flowing through it. If the oil flow is completely interrupted on the route just mentioned, this accordingly has an interruption in the supply of heat to the tenth gas line 78 and the ninth gas line 77 result in air flowing through. The temperature of the exhaust air falls accordingly when - as already described a little further above in the present paragraph - the mentioned thermostatic valve - ie the first flow control valve device 148 - the oil supply from the sixth liquid line 82 into the seventh hollow cylinder 67 completely or partially interrupts and instead that from the sixth liquid line 82 incoming oil accordingly wholly or partly into the thirteenth liquid line 147 leads. The exhaust air is then heated less, is released into the environment in a “cooler” way or is used for further purposes. If at some point later the exhaust air temperature should be regarded as too low, then the position of the said thermostatic valve - ie the first flow control valve device 148 - be changed so that again more or even all of the oil that flows through the sixth liquid line 82 at the first flow control valve device 148 arrives, in the seventh hollow cylinder 67 and in this way the one in the tenth gas line 78 and in the ninth gas line 77 the flowing air is supplied with heat or more heat.

• It is initially in the eighteenth chamber 116 Oil and in the fifteenth chamber 113 Air. The one for the fifteenth gas connection device 117 The associated valve device is opened so that air from the fifteenth chamber 113 via the fifteenth gas connection device 117 can escape. The one for the sixteenth gas connection device 118 The associated valve device is opened in such a way that compressed air flows through the sixteenth gas connection device 118 into the sixteenth chamber 114 can be introduced. The one for the sixth fluid connection device 122 The associated valve device is closed. The one to the eighth fluid connection device 120 The associated valve device is open. The one to the fifth fluid connection device 121 The associated valve device is open, and that of the seventh fluid connection device 119 The associated valve device is closed.

Now through the sixteenth gas connection device 118 Compressed air into the sixteenth chamber 114 introduced, resulting in a lifting of the second piston rod 109 including the seventh piston 110 and the eighth piston 111 leads. Accordingly, the air from the fifteenth chamber becomes 113 through the fifteenth gas connection device 117 pushed out the oil from the eighteenth chamber 116 is through the eighth fluid connection device 120 pushed out, and through the fifth fluid connection device 121 becomes oil in the seventeenth chamber 115 sucked into it. The sixteenth chamber cools down 114 The compressed air released into it is released when the pressure is released, but is done by the eighth piston 111 therethrough a heat exchange with that in the eighteenth chamber 116 located oil, which is regularly warm or at least has room temperature, so that in this way the temperature drop in the air is at least mitigated when relaxing.

Once the second piston rod 109 with the eighth piston fixed on it 111 and the seventh piston fixed on it 110 has reached its top dead center, becomes the fifteenth gas connection device 117 belonging valve device switched so that compressed air into the fifteenth chamber 113 through the fifteenth gas connection device 117 can be introduced. The one for the sixteenth gas connection device 118 The associated valve device is switched over in such a way that the air from the sixteenth chamber 114 through the sixteenth gas connection device 118 can be led out. The one for the sixth fluid connection device 122 The associated valve device is opened. The one to the eighth fluid connection device 120 The associated valve device is closed. The one to the fifth fluid connection device 121 The associated valve device is closed, and that of the seventh fluid connection device 119 The associated valve device is opened.

Now through the fifteenth gas connection device 117 Compressed air into the fifteenth chamber 113 introduced, resulting in a stroke of the second piston rod 109 including the seventh piston 110 and the eighth piston 111 leads down. Accordingly, the air from the sixteenth chamber becomes 114 through the sixteenth gas connection device 118 pushed out through it, the oil from the seventeenth chamber 115 is through the seventh fluid connection device 119 pushed out, and through the sixth fluid connection device 122 will oil the eighteenth chamber 116 sucked into it. The fifteenth chamber cools down 113 The compressed air released into it is released when the pressure is released, but is done by the seventh piston 110 therethrough a heat exchange with that in the seventeenth chamber 115 located oil, which is regularly warm or at least has room temperature, so that in this way the temperature drop in the air is at least mitigated when relaxing.

Once the second piston rod 109 with the eighth piston fixed on it 111 and the seventh piston fixed on it 110 has reached its bottom dead center again, becomes the sixteenth gas connection device 118 The associated valve device is switched over again in such a way that compressed air flows through the sixteenth gas connection device 118 into the sixteenth chamber 114 can be introduced. The one for the fifteenth gas connection device 117 The associated valve device is switched so that air from the fifteenth chamber 113 via the fifteenth gas connection device 117 can escape. The one for the sixth fluid connection device 122 The associated valve device is closed. The one to the eighth fluid connection device 120 The associated valve device is opened. The one to the fifth fluid connection device 121 The associated valve device is opened, and that of the seventh fluid connection device 119 The associated valve device is closed.

Then compressed air is again passed through the sixteenth gas connection device 118 into the sixteenth chamber 114 let into it, and the stroke cycle of the second piston rod already described above 109 including the seventh piston 110 and the eighth piston 111 upwards begins again.

This in 13th Shown second embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 138 Although it differs in some details from the above-described first exemplary embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 137 , however, the same or substantially the same parts are in the 12th and 13th each provided with the same reference numerals.

This in 13th illustrated second embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 138 points to the in 12th illustrated first embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 137 additionally a tenth hollow cylinder 124 on, which is inside the ninth hollow cylinder 106 is arranged to pass through the opening in the third central part 112 extends therethrough and at its one end through an opening in the thirteenth end wall 107 through and at its other end through an opening in the fourteenth end wall 108 through over the thirteenth front wall 107 or over the fourteenth front wall 108 extends beyond. Another special feature of the second exemplary embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 138 is that the second piston rod is the first piston tube 123 is formed, which is the tenth hollow cylinder 124 encloses, hydraulically-pneumatically sealing on the tenth hollow cylinder 124 hugs and is designed so that it sits on the tenth hollow cylinder 124 can slide back and forth. Accordingly, both the seventh piston are of course 110 as well as the eighth piston 111 each provided with a hole through which the tenth hollow cylinder 124 extends, and both the seventh piston 110 as well as the eighth piston 111 cling to the tenth hollow cylinder with a hydraulic-pneumatic seal 124 and are designed to work with the first piston tube 123 on which they are fixed, on the tenth hollow cylinder 124 can slide back and forth. Furthermore, as a special feature of the second exemplary embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 138 an eleventh fluid line 125 provided, which for the purpose of liquid transport both to the fifth liquid connection device 121 as well as to the sixth fluid connection device 122 as well as at that end of the tenth hollow cylinder 124 , which over the thirteenth front wall 107 protrudes, is connected. Via a twelfth liquid line 126 , which for the purpose of liquid transport to that end of the tenth hollow cylinder 124 , which over the fourteenth front wall 108 protrudes, is connected, liquid, for example oil, can enter the tenth hollow cylinder 124 are pressed in and from there via the eleventh liquid line 125 both to the fifth fluid connection device 121 as well as to the sixth fluid connection device 122 flow there.

From a comparison of the 12th and 13th it becomes immediately and readily clear that - apart from the purely constructive differences outlined - the second exemplary embodiment of the pressurized gas energy conversion heat exchanger device upstream device according to the invention 138 in principle functions in exactly the same way as the first exemplary embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention, which is described in detail above in terms of its mode of operation 137 . However, due to the pressure gas energy conversion heat exchanger device upstream device according to the invention in the second exemplary embodiment 138 through the tenth hollow cylinder 124 oil flowing through a larger and better arranged surface for the heat exchange between the liquid and the gas is available, so that in the second embodiment of the inventive compressed gas energy conversion heat exchanger device preliminary stage device 138 an even better heat exchange effectively takes place during operation than in the first exemplary embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 137 .

17th shows a third embodiment of a compressed gas energy conversion heat exchanger device upstream device according to the invention 149 which is opposite to the above with reference to the 13th described second embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 138 is provided with some additional components that provide some control over the operation of the compressed gas energy conversion heat exchanger pre-stage device 149 enable in thermal terms. The background to this additional technical measure is that, with regard to changing ambient temperatures at the place of use of a compressed gas energy conversion heat exchanger device preliminary stage device according to the invention and / or with regard to possibly changing operating requirements in the technical-technological environment of a compressed gas energy conversion heat exchanger device according to the invention Pre-stage device can be useful during the use of the compressed gas energy conversion heat exchanger device pre-stage device and sometimes it may even be absolutely necessary to control the temperature of the exhaust air or the exhaust gas in a targeted manner. While it can be advantageous, for example, in the deepest winter when the outside temperature is very cold, to have the highest possible exhaust air temperature so that the compressed gas energy conversion heat exchanger pre-stage device does not partially freeze and thus perhaps even - if, for example, the compressed gas energy conversion heat exchanger pre-stage device is autonomous , ie is operated without a downstream compressed gas energy conversion heat exchanger device - the exhaust air can be used to heat any room, the same high exhaust air temperature in high summer at high outside temperatures can be useless or even entirely counterproductive and entirely undesirable. At least the risk of partial freezing of the compressed gas energy conversion heat exchanger device upstream device is lower in high summer than in deep 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 upstream device is used to leave more heat in the oil in summer for further use there, while in winter it may 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 liquid as a heat transfer medium. Accordingly, providing thermal control is advantageous and desirable. For this purpose, the in 17th illustrated third embodiment of the inventive compressed gas energy conversion heat exchanger device pre-stage device 149 in addition to the in 13th The following components already shown are provided: a fourteenth liquid line 150 which with one end to the twelfth liquid line 126 connected and set up so that this fourteenth liquid line 150 is able to get liquid from the twelfth liquid line 126 to the fifth fluid connection device 121 and to the sixth fluid connection device 122 to conduct without the liquid on its way to the fifth liquid connection device 121 and to the sixth fluid connection device 122 the tenth hollow cylinder 124 passes through, the connection of the fourteenth liquid line 150 to the twelfth liquid line 126 with a second flow control valve device 151 is provided, which is controllable and designed such that by means of the second flow control valve device 151 can be controlled what proportion of one of the twelfth liquid line 126 at the second flow control valve means 151 incoming liquid flow into the tenth hollow cylinder 124 and what proportion in the fourteenth liquid line 150 is conducted, the control possibility of the second flow control valve device 151 this includes at least the possibility to control whether the liquid line with her is via the twelfth fluid line 126 incoming liquid flow completely into the tenth hollow cylinder 124 or completely into the fourteenth liquid line 150 is directed. This is in 17th illustrated third embodiment of the inventive compressed gas energy conversion heat exchanger device pre-stage device 149 specially set up so that here the fourteenth fluid line 150 with theirs from the second flow control valve device 151 distant end into the eleventh fluid line 125 flows out.

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

It is particularly preferably provided that the second flow control valve device 151 is set up in such a way that, in addition to the aforementioned control option, the complete initiation of the with her over the twelfth Liquid line 126 incoming liquid flow either into the tenth hollow cylinder 124 or in the fourteenth liquid line 150 is also controllable in such a way that it uses the twelfth liquid line with her 126 can split incoming liquid flow, so that part of the liquid in the tenth hollow cylinder 124 and at the same time another part of the liquid enters the fourteenth liquid line 150 arrives, wherein an associated flow division ratio can be controlled continuously and / or in steps. The second flow control valve device controls 151 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 where the gas flows. A temperature measurement is preferred where the gas has already "worked", ie has already expanded.

This measurement or measurements just mentioned is / are advantageously set up, for example, in such a way that, if a gas temperature measurement is used to control the second flow control valve device 151 is carried out, this gas temperature measurement at least either in the area of the fifteenth gas connection device 117 or in the area of the sixteenth gas connection device 118 takes place or in an area of the fifteenth chamber 113 which from the third middle part 112 is further spaced than from the thirteenth end wall 107 or in an area of the sixteenth chamber 114 which from the third middle part 112 is further spaced than from the fourteenth end wall 108 , and that provided a liquid temperature measurement for controlling the second flow control valve device 151 is made, this liquid temperature measurement at least either in the eleventh liquid line 125 takes place or in a region of the tenth hollow cylinder 124 which from the third middle part 112 is further spaced than from the thirteenth end wall 107 .

The control of the second flow control valve device 151 can for example take place 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 17th illustrated third embodiment of the inventive compressed gas energy conversion heat exchanger device pre-stage device 149 In thermal terms, for example, it can be done as follows: First is the second flow control valve device 151 , which can be a thermostatic valve, set in such a way that everything on that thermostatic valve is via the twelfth liquid line 126 incoming oil exactly as in the embodiment of 13th permanently provided and in that embodiment, due to the technical structure provided there, no other way possible, in the tenth hollow cylinder 124 is steered and proceeded from there exactly as it is referred to above 13th was described, moved on. If by means of a measurement of the temperature of the exhaust air, which is in the area of the fifteenth gas connection device 117 takes place, it is determined that the temperature of the exhaust air is higher than necessary or permitted due to any previously defined conditions, the thermostatic valve mentioned in the previous sentence is controlled mechanically or electromechanically in such a way that the oil supply from the twelfth liquid line is controlled 126 into the tenth hollow cylinder 124 completely or partially interrupts and instead that from the twelfth liquid line 126 incoming oil accordingly in whole or in part in the fourteenth liquid line 150 and from there to the fifth fluid connection device 121 and to the sixth fluid connection device 122 leads. To the fifth fluid connection device 121 and to the sixth fluid connection device 122 the oil as such arrives in both the embodiment of FIG 13th as well as in the embodiment of 17th always. While in the embodiment of 13th however, only a single path is permanently provided for the oil there, there is in the embodiment of FIG 17th two different paths for the oil to the fifth fluid connection device 121 and to the sixth fluid connection device 122 , whereby it can be controlled which route the oil should take or how the oil is distributed quantitatively over the two possible routes. The less oil in the tenth hollow cylinder 124 flows, the less heat can be transferred from the oil to the one in the sixteenth chamber 114 and those in the fifteenth chamber 113 any air present are transferred. If the oil flow is completely interrupted on the path just mentioned, this accordingly has an interruption in the supply of heat to the one in the sixteenth chamber 114 and those in the fifteenth chamber 113 resulting air. The temperature of the exhaust air falls accordingly when - as already described a little further above in the present paragraph - the mentioned thermostatic valve - ie the second flow control valve device 151 - the oil supply from the twelfth liquid line 126 into the tenth hollow cylinder 124 completely or partially interrupts and instead that from the twelfth liquid line 126 incoming oil accordingly in whole or in part in the fourteenth liquid line 150 leads. The exhaust air is then heated less, is released into the environment in a “cooler” way or is used for further purposes. If later, the exhaust air temperature should be regarded as too low, the position of the said thermostatic valve - ie the second flow control valve device 151 - be changed so that again more or even all of the oil that flows through the twelfth liquid line 126 at the second flow control valve means 151 arrives, in the tenth hollow cylinder 124 and in this way the one in the sixteenth chamber 114 and the one in the fifteenth chamber 113 heat or more heat is fed back into the air.

With reference to the 14th and 15th Exemplary embodiments of compressed gas energy conversion devices according to the invention are described below.

A compressed gas energy conversion device according to the invention differs from the compressed gas energy conversion devices known from the prior art in that it has at least one group of two, which comprises a compressed gas energy conversion heat exchanger device according to the invention and a compressed gas energy conversion heat exchanger device upstream device according to the invention, which is the compressed gas energy conversion heat exchanger device Preliminary stage is operationally upstream, has. It is very 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 just as well 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 practical economic reasons, but the compressed gas energy conversion device according to the invention can in principle also be operated with any other liquid, for example with water.

The purpose of the compressed gas energy conversion device according to the invention in its different 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 relieving 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 the figures of the present application, all fluid connections or oil connections that are welded or otherwise fastened to the hollow cylinders or that are guided through channels in the central part are provided with check valves, so that the desired required fluid flow or flow is always achieved without electrically or pneumatically controlled valves. Oil flow is achieved. If a chamber becomes full, the valve to the motor / consumer closes due to the resulting negative pressure 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, with the resulting overpressure opening the corresponding valve and at the same time closing the valve to the liquid tank / liquid storage container or oil tank / oil storage container. Basically, this system works like a heart, and the check valves can be viewed as 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 preliminary stage 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 according to the invention is optimally also connected upstream of this whole 50 although the latter is not absolutely necessary. The compressed air is in the compressed gas energy conversion device 50 regulated as precisely as possible to the desired pressure or, if necessary, readjusted in the compressed gas energy conversion heat exchanger pre-stage device by equipping the piston rod or a piston with a position measuring system that allows, after a previously calculated distance covered by the pistons, the to close the respective gas inlet valve in order to use the expansion of the compressed air.

As a compressed gas energy conversion heat exchanger device upstream device in the embodiment of the compressed gas energy conversion device according to the invention from 14th the first embodiment of the compressed gas energy conversion heat exchanger device upstream device according to the invention 137 used, which was already mentioned above with reference to 12th had been described. This first embodiment of the compressed gas energy conversion according to the invention Pre-stage heat exchanger device 137 consists of the ninth hollow cylinder 106 that goes through the third middle section 112 is divided into two equal halves. Through this third middle section 112 guides the second piston rod 109 , at the ends of which the seventh piston 110 and the eighth piston 111 are mounted. This creates four chambers. Between the thirteenth front wall 107 and the seventh piston 110 the fifteenth chamber 113 for air. Between the seventh piston 110 and the third middle part 112 the seventeenth chamber 115 for oil. Between the third middle section 112 and the eighth piston 111 the eighteenth chamber 116 for oil and between the eighth piston 111 and the fourteenth front wall 108 the sixteenth chamber 114 for air.

If necessary, the second piston rod can be used to improve the heat exchanger function 109 the compressed gas energy conversion heat exchanger precursor device as a first piston tube 123 be designed or by the first piston tube 123 be replaced. Through this first piston tube 123 as well as through the thirteenth front wall 107 and the fourteenth front wall 108 and the third middle part 112 becomes the tenth hollow cylinder 124 out through which oil can then be sucked in and so the fifteenth chamber 113 and the sixteenth chamber 114 in which there is air can also be "heated" from the inside (cf. 13th shown second embodiment of the compressed gas energy conversion heat exchanger device pre-stage device 138 ).

In the further description, however, for the sake of simplicity, the oil is simply drawn in via the fifth fluid connection device 121 and the sixth fluid connection device 122 went out without the special possibility of sucking in the oil via the twelfth liquid line 126 , the tenth hollow cylinder 124 and the eleventh liquid line 125 to mention.

In the ideal case, compressed air is now obtained from the compressed air storage tank via the compressed gas energy conversion device 50 regulated to the desired pressure and thus fed to the compressed gas energy conversion heat exchanger device pre-stage device, for example via the fifteenth gas connection device 117 . This becomes the fifteenth chamber 113 filled with compressed air, and accordingly the seventh piston 110 , the second piston rod 109 and the eighth piston 111 pressed down. The sixteenth gas connection device 118 is open to the tenth gas line 78 .

The seventh fluid connection device is meanwhile 119 , from which an oil pressure line leads to an oil motor, is opened. The eighth fluid connection device 120 is closed. The fifth fluid connection device 121 is closed, and the sixth fluid connection device 122 is open for the purpose of sucking in oil.

The compressed air supply to the sixteenth gas connection device 118 is of course closed. Has the eighth piston 111 the fourteenth front wall 108 reached, the compressed air supply to the fifteenth gas connection device closes now at the latest 117 , and a connecting line opens from the fifteenth gas connection device 117 to the ninth gas line 77 .

The compressed gas energy conversion heat exchanger device 60 is now starting to work just as it is referring to above 11 has been described. Once this working cycle has been carried out, the sixteenth gas connection device is now connected 118 to the tenth gas line 78 closed and the sixteenth gas connection device 118 pressurized. The eighth piston 111 and the seventh piston 110 are now accordingly pushed upwards until the seventh piston 110 has reached the thirteenth end wall.

The seventh fluid connection device is here 119 closed to the oil motor. The eighth fluid connection device 120 is open and connected to the oil motor via a pressure line. The fifth fluid connection device 121 is open to suck in oil, and the sixth fluid connection device 122 is closed.

The compressed air supply now becomes the sixteenth gas connection device 118 closed and the connection to the tenth gas line 78 open. The rest of the process is then as above with reference to FIG 11 described.

It is of course not absolutely necessary to stop the compressed air supply when the top or bottom dead center of the seventh piston is reached 110 and the eighth piston 111 to interrupt. In particular when the pressures available are low, it can be useful to maintain the supply of compressed air until the compressed gas energy conversion heat exchanger device has also performed the desired work cycle in whole or in part.

From the combination of the compressed gas energy conversion according to the invention Heat exchanger device preliminary stage device and the compressed gas energy conversion heat exchanger device according to the invention as a group of two is an embodiment of a compressed gas energy conversion device according to the invention. The combination of these two units, ie the pressurized gas energy conversion heat exchanger device upstream device according to the invention and the pressurized gas energy conversion heat exchanger device according to the invention, and the associated valves is now referred to below as a “unit”. It is possible to use the compressed gas energy conversion heat exchanger device upstream 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 one behind the other or in parallel.

In particular with reference to 15th and with simultaneous recourse to 14th A compressed gas energy conversion device in which two units are interconnected will now be described as a further possible embodiment of the compressed gas energy conversion device according to the invention.

It is assumed that in both units in the compressed gas energy conversion heat exchanger device preliminary stage device according to the invention, both the seventh piston 110 as well as the eighth piston 111 are initially at top dead center. The fifth piston is located in the respective compressed gas energy conversion heat exchanger device of the two units according to the invention 69 and the sixth piston 70 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, for example from a storage container via a pressure reducer or from a compressed gas energy conversion device according to the invention 50 .

Air, for example, can be used as the gas. But it is just as well 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.

Tact 1 opens on a first four-way valve block 127 the first unit a first valve 128 , and pressurized gas then flows through a thirteenth gas line 144 into the fifteenth chamber 113 . The seventh piston 110 and the eighth piston 111 are pushed to bottom dead center. In doing so, oil is drawn from the seventeenth chamber 115 via the seventh fluid connection device 119 , from which an oil pressure line leads to the oil motor, is pressed to the oil motor.

The fifth fluid connection device is here 121 closed. The sixth fluid connection device 122 is open, and via the sixth fluid connection device 122 the eighteenth chamber sucks 116 full of oil.

On a second four-way valve block 132 is a fifth valve 133 Supply line closed. A sixth valve 134 , a seventh valve 135 and an eighth valve 136 are always open.

Air from the sixteenth chamber 114 as well as from the fourteenth chamber 76 the first unit and from the ninth chamber 71 the second unit can now escape into the atmosphere or via the eighth valve 136 another consumer, for example a buoyancy power plant, a turbine or the like, are supplied. Is the fifteenth chamber 113 completely filled with gas, the first valve closes 128 and interrupts the supply of compressed air via the first compressed gas supply line 100 .

Now clock begins 2 at the first unit, and at the same time bar begins 1 on the second unit. The second valve 129 opens the pressurized gas from the fifteenth chamber 113 flows through the thirteenth gas line 144 and the fourteenth gas line 139 and the ninth gas line 77 into the thirteenth chamber 75 . The fifth piston 69 and the sixth piston 70 are pushed to top dead center. Thereby oil is drawn from the twelfth chamber 74 via the eighth liquid line 95 pressed towards the oil motor. The ninth liquid line 96 is closed, and so is the seventh liquid line 94 to the oil motor is closed. The tenth fluid line 97 is open to suck in oil, so that the eleventh chamber 73 via the tenth liquid line 97 soaked with oil. The seventh fluid line 94 to the oil motor is closed. At the time specified at the beginning of this paragraph, ie at the beginning of the measure 2 at the first unit and the simultaneous beginning of the measure 1 on the second unit, must or can be assumed to be in the sixteenth chamber 114 the second unit and in the fourteenth chamber 76 air is present in the second unit after partial relaxation. This air comes in through a nineteenth gas pipe 145 and the fourteenth gas connection device 99 the tenth chamber 72 fed to the first unit. There are on the second four-way valve block 132 the fifth valve of the second unit 133 closed, the sixth valve 134 open, the seventh valve 135 open and the eighth valve 136 closed.

Now clock begins 3rd at the first unit, and at the same time bar begins 2 on the second unit. On the second quadruple valve block 132 of the first unit opens the fifth valve 133 , and pressurized gas then flows through the eighteenth gas line 143 in the sixteenth chamber 114 . The sixth valve 134 is closed.

The seventh valve 135 and the eighth valve 136 are open so that the fourteenth chamber 76 the first unit and the ninth chamber 71 the second unit can be vented or the air can be supplied to a further consumer. The eighth piston 111 and the seventh piston 110 are pushed to top dead center. This is where oil is drawn from the eighteenth chamber 116 via the eighth fluid connection device 120 and pressed an oil pressure line connected to it to the oil motor.

The fifth fluid connection device 121 is open, leaving the seventeenth chamber 115 via the fifth fluid connection device 121 can soak up with oil. The seventh fluid connection device 119 and the sixth fluid connection device 122 are closed.

At the beginning of the bar 2 the second unit opens at the first four-way valve block 127 the third valve of the first unit 130 , and the still pressurized gas from the thirteenth chamber 75 as well as that through the upward movement of the seventh piston 110 and the eighth piston 111 - triggered by the beat 3rd - displaced gas from the fifteenth chamber 113 the first unit now flows through a fifteenth gas line 142 to the fourteenth gas connection device 99 into the tenth chamber 72 and supports the movement of the fifth piston there 69 and the sixth piston 70 to top dead center during the cycle 2 the second unit. Has the compressed gas energy conversion heat exchanger pre-stage device of the first unit the clock 3rd when the seventh piston reaches top dead center 110 and the eighth piston 111 completed, then begins with the first unit bar 4th and clock for the second unit 3rd .

The first unit opens on the second four-way valve block 132 the sixth valve 134 , and the compressed gas of the sixteenth chamber 114 flows through a sixteenth gas line 140 and the tenth gas line 78 into the fourteenth chamber 76 . The fifth piston 69 and the sixth piston 70 are pushed to bottom dead center. This is where oil is drawn from the eleventh chamber 73 pressed through the seventh fluid line to the oil motor.

The tenth fluid line 97 is closed. Also the eighth liquid line 95 to the oil motor is closed.

The ninth liquid line 96 is open, so that the twelfth chamber 74 via this ninth liquid line 96 can soak up with oil.

At the beginning of the measure 4th the first unit and the measure 3rd the second unit opens at the first four-way valve block 127 the fourth valve of the first unit 131 , and the remaining pressurized gas from the thirteenth chamber 75 the first unit and the tenth chamber 72 the second unit can be released into the atmosphere or fed to a further consumer.

Now the first unit starts again with a beat 1 , and the second unit begins with bar 4th . With the second four-fold valve block 132 the seventh valve of the first unit 135 open, and through a seventeenth gas pipe 141 and the thirteenth gas connection device 98 becomes the ninth chamber 71 the second unit, the partially expanded compressed gas from the sixteenth chamber 114 and the fourteenth chamber 76 fed to the first unit and supports the movement of the fifth piston 69 and the sixth piston 70 the second unit in the direction of bottom dead center during the cycle 4th . Is the tact 4th the second unit ends, opens at the second four-fold valve block 132 the eighth valve of the first unit 136 and releases the residual pressure gas into the atmosphere or feeds it to the next consumer.

This sequence described in the previous paragraphs on the mode of operation of the compressed gas energy conversion device is now repeated continuously. The arrival of the pistons at the end points can be determined with a position 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 series of units can be expanded as required and thus the scope of the compressed gas energy conversion device according to the invention can be expanded as required.

In the above-described embodiments of the compressed gas energy conversion device according to the invention 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 fed to further work, e.g. a buoyancy power plant or a turbine. However, if the "exhaust air" is only to be used thermally (extraction of heat), it is advisable to switch between three, four, five or six units or groups of two in a row in order to gain time and to ensure that the "exhaust air" is blown off before the next work cycle begins. If one considers the oil motors, which are operated by the individual compressed gas energy conversion heat exchanger devices and by the individual compressed gas energy conversion Heat exchanger device pre-stage devices are driven, connected to one another by means of a continuous shaft and if the quantities of oil consumed by the oil motors are compatible with the displaced oil quantities of the individual compressed gas energy conversion heat exchanger devices and the individual compressed gas energy conversion heat exchanger device pre-stage devices, the processes or cycles of the individual units always run evenly and harmoniously, and the oil motors then act like a flow divider.
