Furthermore, this passage plate is in airtight contact with the connection area by a second connecting surface which is particularly aligned parallel to the narrow side surface. Within the passage plate, a plurality of coupling passages are formed, each of which is formed for coupling between one valve assembly within the valve assembly and one passage opening within the passage opening. 【0006】 In particular, having one or more valve modules, Each of the valve modules has a valve housing, This valve housing is positioned on each of the aforementioned connection points in a region, with its narrow side surface, and Within this valve housing, one duct, or multiple ducts aligned parallel to each other, are formed. It is intended that the duct opening of the duct is located at the valve housing end face within a common duct opening plane that is aligned laterally with respect to the narrow side surface. Furthermore, the valve module system includes at least one valve assembly, The valve assembly is housed in one of the ducts of the valve housing, At the end face of the valve assembly, which is located within the region of the duct opening, A first valve connection portion and a second valve connection portion are formed. 【0007】 Within the first control passage assigned to the first valve connection and / or the second control passage assigned to the second valve connection, The valve seat, Electrically controllable, and the closed position and before the valve seat. Defendant A valve member is positioned which is movable between an open position for the seat. In that case, The valve housing is equipped with a passage plate, This passage plate is sealed by the first connecting surface to the valve housing end face and / or the valve assembly, and in particular, it is sealed in contact with the end face of the valve assembly, and The passage plate is sealed and abuts against the connection area by a second connecting surface which is aligned parallel to the narrow side in particular. Within the passage plate, a plurality of coupling passages are formed, and each of these coupling passages is intended to be formed for coupling the first valve connection and the second valve connection with a single passage opening. 【0008】 The primary function of the support plate is to mechanically secure at least one valve module, and more particularly, multiple valve modules, in which the multiple valve modules are arranged adjacent to each other, preferably with sides facing each other along a direction of alignment. Advantageously, the valve housing of the valve module has two sides aligned parallel to each other, where these sides are joined by narrow sides, where at least one of these narrow sides is formed for contact with the connection portion of the support plate. Advantageously, it is intended that this narrow side surface is formed flat, and that the corresponding connecting portion on the support plate is similarly formed flat. 【0009】 Within the support plate, multiple fluid passages extend, formed for the supply or discharge of fluid to or from passage openings provided within the connection area of ​​the connection portion. Advantageously, the valve housing is sized such that it does not obstruct the connection area with the passage openings realized therein, thus ensuring free access to the passage openings when the valve housing is mounted on the support plate. 【0010】 The valve housing may be formed, for example, in a rectangular parallelepiped shape and may have a plurality of ducts that are spaced apart from each other at a certain pitch and oriented parallel to each other, particularly at end faces that are oriented perpendicular to the narrow sides intended for contact on the support plate. The parallel orientation of these ducts is given by the fact that each of these ducts extends into the valve housing along its extension axis in the manner of a recess, and that the extension axes of these ducts are oriented parallel to each other. Furthermore, the duct outlet openings, also referred to as duct openings, are intended to be located within a common duct opening plane, aligned laterally to the narrow side. Advantageously, these ducts are formed with a certain contour, at least partially, along their respective extension axes, and this contour is intended to be selected so that a valve assembly can be inserted into each of these ducts. 【0011】 The valve assembly comprises a first valve connector and a second valve connector, each of which demarcates one outlet opening for its assigned control passage. It is intended that the first control passage is assigned to the first valve connector, and the second control passage is assigned to the second valve connector. Furthermore, within at least one control passage, a valve seat and an electrically controllable valve member that is movable between a closed position for the valve seat and an open position for the valve seat are arranged, and so it is intended that the cross-sectional area of ​​each control passage can be changed. Advantageously, the valve member is intended to release the maximum cross-sectional area of ​​the control passage in the open position and to completely close the control passage in the closed position. 【0012】 Furthermore, the valve module system includes a replaceable passage plate, and the challenges with this passage plate are... The intention is to form a fluidly communicating connection between each valve assembly and the assigned connection region having a passage opening provided therein. For this purpose, the passage plate has a first connecting surface which seals tightly against the outlet opening of the duct or the end face of a valve assembly housed within the respective duct, and in particular, The connection between the first valve connection and the coupling passage formed within the passage plate, particularly the first coupling passage 43, and This ensures a sealed connection between the second valve connection and the coupling passage or first coupling passage formed in another passage plate. In this configuration, it is intended that the coupling passage is in a state of fluid communication with each of the passage openings in the connection region at a second coupling surface oriented parallel to the narrow side surface of the valve housing, and that this second coupling surface is in airtight contact with the connection region. Advantageously, the passage plate is intended to be formed in a rectangular parallelepiped shape, and the first and second connecting surfaces are each formed flat and aligned perpendicularly to each other. 【0013】 Depending on the assignment provided for each coupling passage between the first valve connection part and one or more passage openings in the connection area, as well as between the second valve connection part and one or more passage openings in the connection area, different functions can be configured for each valve assembly, or for a plurality of valve assemblies belonging to each valve module. For this purpose, in particular, it is intended to select a passage plate with a corresponding course of the coupling passage from a plurality of differently configured passage plates, and to assign this passage plate to each valve module and to the assigned connection area. 【0014】 Advantageous further configurations of the invention are the subject of the dependent claims. 【0015】 It is expedient if the passage plate abuts in a sealed manner against the end face of the valve housing penetrated by the duct opening and delimits a pressure chamber together with the duct, in which at least one of the valve assemblies is accommodated. For example, a plate-shaped elastomeric sealing material is arranged between the passage plate and the end face of the valve housing penetrated by the duct and having a duct opening formed at its end face of the valve housing, where this sealing material forms a common pressure chamber for all ducts covered by the passage plate, or each duct covered by the passage plate forms a separate pressure chamber, or groups of these ducts are intended to form a common pressure chamber. Optionally, in the assembled state, the end face of the passage plate facing the end face of the valve housing is provided with a ring-shaped sealing material made of an elastomeric material for each, which is formed for the individual sealing of each duct opening, and thus it is intended that a separate pressure chamber is provided for each valve assembly. In yet another option, each of these duct openings is surrounded by a ring-shaped seal made of a rubber-elastic material, and the end face of the passage plate is sealingly pressed against this seal in the assembled state, so that, likewise, a dedicated pressure chamber is intended to be provided for each valve assembly. Advantageously, it is intended that a common pressure load or negative pressure load for each pressure chamber is effected via a corresponding connecting passage in the passage plate. 【0016】 In an alternative embodiment, the valve assembly sealingly abuts against the inner surface of the duct by means of a circumferentially extending seal and delimits a pressure chamber together with the duct, and a supply connection coupled to the pressure chamber is formed at the end face of the valve housing or of the valve assembly, and this supply connection is intended to be coupled to a connecting passage in the passage plate so as to be in fluid communication. Advantageously, the valve assembly is formed in the manner of a cartridge or a cartridge, which, viewed by themselves, do not have functionality in the individual state, but rather are only placed in the functional state for the first time by being assembled into the duct of the valve housing. This should be attributed to the fact that the valve assembly does not have any specific, pressure-sealed housing, but rather has to rely on a sealed accommodation in the duct. For this purpose, it is intended that the valve assembly sealingly abuts against the inner surface of the duct by means of a circumferentially extending seal and, thereby, delimits a pressure chamber by the duct. Starting from this pressure chamber, a first control passage assigned to a first valve connection and a second control passage assigned to a second valve connection extend. Furthermore, as in the first control passage, the second control passage is also intended to have one valve seat and an electrically controllable valve member in each. A supply connection is provided for supplying compressed air, process gas, a process gas mixture, or negative pressure to the pressure chamber, and through this supply connection, fluid can be supplied to the pressure chamber by excess or negative pressure. When sealing is performed between the passage plate and the valve housing, the supply connection is formed in the passage plate and is intended to be in fluid communication with the assigned passage opening within the connection area via an assigned coupling passage within the passage plate. Insofar as the valve assembly is sealed within each duct by a surrounding sealing material, and only in this way is the pressure chamber partitioned, the supply connection can be selectively formed on the valve housing or the end face of the valve assembly, and in this case, it is in fluid communication with an assigned connecting passage in the passage plate and is coupled to an assigned passage opening in the connection area. 【0017】 Advantageously, the support plate is intended to have a connecting surface, at least a portion of the fluid passage opening at this connecting surface, and at least one fluid connection portion being assigned to the fluid passage opening at the connecting surface. Fluid passages that open at the connecting surface and each having one fluid connection portion enable the connection of fluid conduits, particularly flexible fluid ducts, which can themselves be connected to, for example, a compressed air source, a negative pressure supply source, or a working connection portion of a compressed air consumption unit. Accordingly, the fluid coupling portion forms a fluid-technical connection between the valve module system and the assigned supply device or compressed air consumption unit. Advantageously, each fluid passage formed within the support plate is intended to open at the coupling surface and be equipped with the assigned fluid coupling portion. 【0018】 In yet another embodiment of the present invention, The connection region has a first outlet opening, and the first fluid passage to which it belongs is connected to a first working connection portion located on the connecting surface, and The connection region has a second outlet opening, and the second fluid passage to which it belongs is connected to a second working connection portion located on the connecting surface, and The connection region has a third outlet opening, and the third fluid passage to which it belongs is connected to a first fluid connection portion, particularly a compressed air connection portion, located on the connecting surface, and It is intended that the connection region has a fourth outlet opening, and that the fourth fluid passage to which it belongs is connected to a second fluid connection portion, in particular an exhaust connection portion, located on the connecting surface. 【0019】 This configuration, with outlet openings provided in connection regions and connecting portions located on the connecting surfaces, can realize a typical operating method for a valve module system. For example, it is intended that a compressed air source is connected to a first fluid connection portion on the connecting surface, and that this compressed air source is coupled to a plurality of third outlet openings within a plurality of connection regions via an assigned third fluid passage. In the same manner, this also applies to a second fluid connection formed on the connecting surface, which is connected to a plurality of fourth outlet openings in a plurality of connection regions via a fourth fluid passage and can be used, for example, as an exhaust passage. In contrast, the first fluid passage and the second fluid passage are intended to be direct connections between a first or second outlet opening assigned to a single connection area and a first or second working connection assigned to the connecting surface. 【0020】 In a more advantageous configuration, A sealing material, preferably formed in the shape of a plate, is disposed between the second connecting surface of the passage plate and the connecting region. This sealing material is intended to be formed for individual seals between the outlet opening and the respective coupling passages. To this end, advantageously, a sealing material manufactured from a rubber-elastic material and having at least a rubber-elastically formed sealing region is permeated by a plurality of passages, each of which serves to ensure a fluid connection between the connecting passage and the assigned outlet opening, with each sealing portion formed extending around each passage to ensure a seal for this fluidly communicating connection. 【0021】 In yet another embodiment of the present invention, The passage plate has individual fluid connections between the first valve connection, the second valve connection, and the supply connection, respectively, and the coupling passages assigned to each valve assembly housed within the valve housing. That is intended. This ensures that for each valve assembly, there is fluid separation between the first valve connection, the second valve connection, and the supply connection within the passage plate and the support plate. Conversely, adjacent valve assemblies located within a common valve housing may be intended to access one or more coupling passages formed within a passage plate, similarly through their respective first valve connections, second valve connections, or supply connections. 【0022】 Within the first control passage, When a valve seat and a valve member that is electrically controllable and movable between a closed position for the valve seat and an open position for the valve seat are arranged, In the second control passage, When a valve seat and a valve member that is electrically controllable and movable between a closed position for the valve seat and an open position for the valve seat are provided, It is advantageous. This allows the fluid communication between the pressure chamber and the first valve connection, and between the pressure chamber and the second valve connection, to be adjusted or completely blocked, depending on the position of the respective valve members. In this case, the first valve member assigned to the first control passage and the second valve member assigned to the second control passage can be controlled by corresponding electrical signals, independently of each other, in order to allow individual adjustment of the cross-sectional area for the second control passage, as with the first control passage. 【0023】 In an advantageous further configuration of the present invention, The aforementioned passage plate, It has a first connecting passage, This first coupling passage is connected to the first valve connector of the first valve assembly and to the first valve connector of the second valve assembly. It has a second connecting passage, This second coupling passage is connected to the second valve connection portion of the first valve assembly and the second valve connection portion of the second valve assembly. It has a third connecting passage, This third coupling passage is coupled to the supply connection portion of the first valve assembly, and It has a fourth connecting passage, This fourth coupling passage is coupled to the supply connection portion of the second valve assembly. That is intended. For example, a first coupling passage is connected to a coupling passage formed within the support plate and opening at the connecting surface, and this coupling passage is intended to be referred to as a first working passage. Furthermore, a second coupling passage is connected to a fluid passage formed within the support plate and opening at the connecting surface, and this fluid passage is intended to be referred to as a second working passage. In this case, a first valve assembly, each having two 2 / 2 directional control valves, and a second valve assembly, each similarly having two 2 / 2 directional control valves, together form a 4 / 3 directional control valve that can be operated in the form of a full bridge structure (Vollbrueckenstruktur). As a result, as long as the third coupling passage is connected to a compressed air source and the fourth coupling passage is formed as an exhaust connection, ventilation or exhaust can be guaranteed for the first coupling passage and the second coupling passage, respectively. 【0024】 In a selective further configuration of the present invention, The aforementioned passage plate, It has a first connecting passage, This first coupling passage connects the first valve connector and the second valve connector of the first valve assembly, and It is connected to the first valve connector and the second valve connector of the second valve assembly, It has a second connecting passage, This second coupling passage is coupled to the supply connection portion of the first valve assembly, and It has a third connecting passage, This third coupling passage is coupled to the supply connection portion of the second valve assembly. That is intended. In this case, the supply of compressed air is guaranteed through the second coupling passage, and exhaust is intended through the third coupling passage. Therefore, in the first coupling passage, the compressed air consumption section connected to the working connection of the first coupling passage can be selectively vented by the control of the first valve assembly and exhausted by the control of the second valve assembly, and in both cases, twice the flow rate can be provided to each. This is because exhaust, as well as venting, can be performed through two independently controllable valve members of each valve assembly. 【0025】 In yet another selective embodiment, The aforementioned passage plate, It has a first connecting passage, This first coupling passage is connected to the first valve connector of the first valve assembly and to the first valve connector of the second valve assembly. It has a second connecting passage, This second coupling passage is coupled to the second valve connector of the first valve assembly and the second valve connector of the second valve assembly, and It has a third connecting passage, This third coupling passage is connected to the supply connection portion of the first valve assembly and the supply connection portion of the second valve assembly. That is intended. In this embodiment of the passage plate, a compressed air consumption unit may be supplied to the first or second coupling passage by the second valve assembly, similar to the first valve assembly, where both of these compressed air consumption units are supplied exclusively by compressed air and no exhaust is intended. This type of compressed air consumption unit can be formed, for example, as a compressed air motor. 【0026】 In yet another embodiment of the present invention, The aforementioned passage plate, It has a first connecting passage, This first coupling passage is connected to the first valve connector and the second valve connector of the first valve assembly, and to the first valve connector and the second valve connector of the second valve assembly. It has a second connecting passage, This second coupling passage is connected to the supply connection portion of the first valve assembly and to the supply connection portion of the second valve assembly. That is intended. In this embodiment of the passage plate, for example, pressure supply to a compressed air consumption section may be performed, in which both valve assemblies selectively shut off or open the fluidly communicating connection between a second coupling passage coupled to a compressed air source and a first coupling passage used as a working connection. In this case, the first valve assembly and the second valve assembly may be used for flow control. 【0027】 In yet another embodiment of the present invention, The valve member is coupled to a piezo drive device, particularly a piezo bending body. The aforementioned piezo drive device is connected to a voltage supply device, and this voltage supply device is electrically coupled to a control device. This control device is intended to be formed to provide control signals for controlling the piezo drive device. Highly accurate proportional valve functions can be achieved by piezoelectric drive units, particularly piezoelectric bends formed in a strip shape (with or without a conductive intermediate layer, monomorph, bimorph, or trimorph). In this case, a valve member formed as a sealing element is intended to be mounted in the end region of the piezoelectric drive unit, and this piezoelectric drive unit is housed in a fixed position within a valve assembly, for example, via a spring-elastically formed three-point support. A piezoelectric drive device, particularly a piezoelectric bending body, requires a voltage to induce deformation, and this voltage must be supplied from a voltage supply device. This voltage supply device is electrically coupled to a control device, which regulates the amount of electrical energy that should be supplied to the piezoelectric drive device by the voltage supply device. Advantageously, the high-voltage supply and control devices are intended to be formed as components of an electronic circuit, in which case the control device is formed in particular as a microprocessor. Particularly advantageously, the voltage supply and control devices are intended to be arranged and formed on a common printed circuit board (PCB). 【0028】 In the fluid passage formed within the support plate, A group of sensors consisting of a pressure sensor, temperature sensor, flow sensor, and humidity sensor has been assigned. The sensor is purposeful if it is electrically coupled to a control device and is formed to provide an electrical sensor signal. Sensors can be used to detect, for example, the supply pressure of a compressed air source, the working pressure for a compressed air consumption unit, or the temperature, volumetric flow rate, and moisture content of a gas flowing in a fluid passage. Electrical sensor signals provided by the sensors are supplied to a control device via sensor wires, where they can be processed. For example, a control device may be configured to perform pressure control for the dominant fluid pressure within a fluid passage. To this end, corresponding control of a valve assembly fluidly connected to the fluid passage is performed. 【0029】 Advantageously, the pressure sensor is intended to be coupled to a sensor passage, which branches off from the fluid passage. Such sensor passages, which may also be called stub conduits, allow for reliable pressure detection for the dominant pressure within the fluid passage, while avoiding the unwanted inclusion of dynamic pressure proportions because no significant fluid flow exists within the sensor passage. This allows for potentially more accurate measurement results compared to sensors directly placed within the fluid passage. 【0030】 In a selective embodiment of a valve module system, The fluid passage formed within the support plate has a constricted portion. A first pressure sensor, formed for providing a pressure-dependent electrical first sensor signal, is assigned to the first end region of the throttling portion, and, A second pressure sensor, formed for providing a second pressure-dependent electrical sensor signal, is assigned to the second end region of the throttling portion, and The first pressure sensor and the second pressure sensor are electrically coupled to the control device, which is configured for processing the signals from the first and second sensors. That is intended. In this embodiment, the throttling section, the first pressure sensor, and the second pressure sensor form a device for measuring the flow rate in the fluid passage. In this case, it is not necessary for the throttling section to have a reduced cross-sectional area compared to the other fluid passages. Rather, it is sufficient that the flow resistance of the throttling section is known in order to enable detection of the pressure difference based on the sensor signals of the sensors located at the ends of the throttling section, and from there, to enable calculation of the desired flow rate. It is equally possible that, selectively, a single pressure sensor is intended to be pneumatically coupled to a first end region of the throttling section and a second end region of the throttling section, and to be formed for detecting differential pressure across the throttling section. 【0031】 Advantageous embodiments of the present invention are illustrated in the figures.

[Modes for carrying out the invention] 【0033】 The valve module system 1 shown in Figure 1 is intended for the fluid supply of compressed air to multiple (not shown) compressed air consumption units, and is shown in an incomplete state for the purpose of clarifying the structure of the valve module system. For illustrative purposes, the valve module system 1 may have a support plate 2 to which multiple valve modules 4, arranged in a row along an axis 15 alongside the communication unit 3, and assigned passage plates 5 may be attached. For illustrative purposes, as shown in Figure 1, only one passage plate 5 is assigned to one of these valve modules 4, while the other valve modules 4 do not have passage plates 5 for illustrative purposes. Communication unit 3, in particular, OPC Integrated Architecture (OPC UA (Open Platform Communication Unified Architecture)), Bus communication system The I / O link allows for data exchange with, for example, a higher-level control device, particularly a programmable logic controller (speicherprogrammierbaren Steuerung (SPS)), or with the control level (Leitebene) or the cloud. This enables the connection of valve module system 1 to a communication system (not shown) consisting of a group of elements. 【0034】 Each valve module of the valve module 4 is equipped with a valve housing 6, within which, specifically exemplary, four ducts 7 are formed, intended for housing a group of valve structural components 18 formed in a cartridge or tube shape. The contour of each valve structural component group 18 is matched to the contour of the duct 7 without the valve assembly 18, as shown in Figure 1, so that the valve structural component group 18 can be inserted into each duct 7. In this configuration, the valve assembly 18 is configured such that it can only be used to control fluid flow when it is installed within the duct 7. Accordingly, the valve assembly 18 is provided with a circumferentially extending seal 28, which is configured for a sealed contact with the inner surface 29 of the duct 7. In this way, the valve assembly 18 and the duct 7 partition a pressure chamber 30, which is illustrated in more detail in Figure 4. 【0035】 A first valve connection portion 20, a second valve connection portion 21, and a supply connection portion 31 are formed on the end face 19 of the valve assembly 18, which are illustrated in more detail in the detailed view of Figure 2. Exemplarily, the first valve connection portion 20 and the second valve connection portion 21 each have one rubber-elastic sealing material 32, while the supply connection portion 31 is intended to be formed as a rectangular connection portion within the end face 19 of the valve assembly 18, exemplarily. The valve assemblies 18 are inserted into the ducts 7 of the valve housings 6 such that the end faces 19 of each valve assembly 18 are aligned flush with the duct opening plane 10 of the valve housings 6. In this case, the duct opening plane 10 is the plane in which the duct openings 9 of the ducts 7 are located. 【0036】 Exemplarily, the valve housing 6, which is formed in a rectangular parallelepiped shape, is placed on a flat connecting surface 11, which is formed in a planar manner, exemplarily, by narrow side surfaces 8 that are aligned perpendicular to the duct opening plane 10. The valve housing 6 is fixed to the support plate 2 by fixing means (not shown), and a predetermined position is provided on the support plate 2 for each valve housing 6, and this position is also referred to as the connecting portion 12. This connection portion 12, in a very exemplary manner, includes a rectangular connection area 13, which is not covered by the valve housing 6 and opens at a plurality of passage openings 14. As illustrated in more detail in Figure 4, each of these passage openings 14 is connected to fluid passages 33 to 36 formed within the support plate 2. For the fluid communication between the valve assembly 18 and the passage openings 14 within the connection region 13, one passage plate 5 is provided for each valve module 4, in which case, for the sake of clarity, only one of these passage plates 5 is shown in Figure 1. 【0037】 The passage plate 5 is fixed in each valve housing 6 and at the connection portion 12 of the support plate 2 in a manner not shown in more detail, and ensures a liquid-tight connection between the first valve connection portion 20, the second valve connection portion 21, and the supply connection portion 31 of each valve assembly 18 and the respective assigned passage opening 14. 【0038】 In a selective modification of one valve module 84, as shown at the top in the arrangement of valve modules 4, 84 in Figure 1, individual seals for each duct 7 are ensured upon contact with the passage plate 5 by a sealant 17 located in a recess of the valve housing end face 16, which extends circumferentially in a ring shape around each duct opening 9. In this case, since the pressure chamber is partitioned by the passage plate 5, the sealant 17, and the duct 7, the sealant 28 and the supply connection 31 provided in the valve assembly 18 can be omitted. This is because the supply from the valve assembly 18 can be achieved by a supply duct 40 located within the passage plate and opening into the pressure chamber, as shown in Figure 3. 【0039】 As is also shown in a general manner in Figure 4, the fluid passages 33 to 36 formed within the support plate 2 terminate at the end face of the support plate 2, which is also called the connecting surface. Each of the fluid passages 33 to 36 opens at the connecting surface 77 of the support plate 2, and at that time, one fluid connection portion 73, 74, 75, 76 is formed in each, and this fluid connection portion is equipped with a fluid connection portion not shown, which enables the connection of, for example, a fluid duct not shown. 【0040】 Figure 3 shows a schematic perspective view of the passage plate 5. The passage plate 5 has four valve connections 37 in total, and these valve connections are arranged at the same pitch, just as they are with respect to the duct 7 within the valve housing 6. Each of these valve connections 37 is provided for a liquid-tight connection to an assigned valve assembly 18. For example, each of these valve connections 37 includes a first housing perforation 38, a second housing perforation 39, and a supply duct 40. In this case, the first housing perforation 38 is used to house the sealant 32 of the first valve connection 20, while the second housing perforation 39 is used for the sealed housing of the sealant 32 of the second valve connection 21. The supply duct 40 can be used for a liquid-tight connection with the supply connection portion 31 at the end face 19 of the valve assembly 18 when the passage plate 5 is used in conjunction with the valve module 4. When the passage plate 5 is used in conjunction with the valve module 84, the supply duct 40 is used for supplying fluid to the pressure chamber partitioned by the passage plate 5, the sealant 17, and the duct 7. 【0041】 The surface of the passage plate 5, which is advantageously flat and includes a valve connection portion 37, is also referred to as the first connecting surface 41. A second connecting surface 42, which is precisely oriented perpendicular to the first connecting surface 41 and has a flat surface, is used for resting on the connecting area 13 of the connection portion 12. At the second connecting surface 42, the first connecting passage 43, the second connecting passage 44, the third connecting passage 45, and the fourth connecting passage 46 are open. Each of the connecting passages 43 to 46 is in a fluidly connected state to one of the two housing perforations 38, 39 or to the supply duct 40, in a manner that will be described in more detail below. 【0042】 Exemplarily, a sealing plate 47 is positioned between the second connecting surface 42 and the connecting region 13, and this sealing plate is intended to be manufactured from a rubber-elastic material, also exemplarily. This sealing plate 47 is perforated by holes 48 corresponding to the arrangement of the connecting passages 43 to 46 within the passage plate 5, and these holes thereby ensure a fluidly connected connection between the passage opening 14 and the connecting passages 43 to 46 within the passage plate 5. 【0043】 As can be seen from the schematic illustration in Figure 4, the valve assembly 18, together with the duct 7, partitions the pressure chamber 30, and this pressure chamber is in a fluidly connected state with the supply connection 31. Within the nozzle carrier 51 belonging to the valve assembly 18, whose outer end face forms the end face 19 of the valve assembly 18, a supply passage 52, a first control passage 53, and a second control passage 54 are formed. In this configuration, the supply passage 52 connects the supply connection 31 to the pressure chamber 30. The first control passage 53 connects the first valve connection 20 to the first valve seat 55. The second control passage 54 connects the second valve connection 21 to the second valve seat 56. A first valve member 57, formed as, for example, a rubber-elastic sealing element, is sealed and placed on the first valve seat 55 as shown in Figure 4. The first valve member 57 is attached to a first piezo element 59, which is formed as a piezo-bent body, and is fixed to the cartridge housing 22 of the valve assembly 18 at the end region opposite to the first valve member 57. In the same manner, as shown in Figure 4, a second valve member 58, similarly formed as a rubber-elastic sealing element, is sealed and placed on the second valve seat 56 of the nozzle carrier 51 and connected to a second piezo element 60, the second piezo element being fixed to the cartridge housing 22 at its end. 【0044】 When the first piezoelectric element 59 is loaded with voltage, bending of the first piezoelectric element 59 is induced, and this bending lifts the first valve member 57 from the first valve seat 55, thus releasing the fluid connection between the pressure chamber 30 and the first valve connection 20. In the same manner, the same applies to the second piezoelectric element 60, which can be bent by voltage, and in this bent position, the second valve member 58 is lifted from the second valve seat 56 to release the fluid connection between the pressure chamber 30 and the second valve connection 21. For supplying these voltages to the first piezoelectric element 59 and the second piezoelectric element 60, an electrically connected wire 61, schematically shown, is provided, which is electrically coupled to the control board 62. A control device 63 is located on the control board 62, and this control device comprises a microprocessor and a voltage generator in a manner not shown in more detail, and the voltage generator is configured for controlling the supply of voltage to cause the desired curvature of the first piezoelectric element 59 and / or the second piezoelectric element 60, depending on a control program running within the microprocessor and on sensor signals as described in more detail below. 【0045】 In optional embodiments not shown for the piezoelectric elements, these piezoelectric elements occupy a curved position in the neutral position without voltage load, so that the valve member or sealing element assigned to each is lifted from its respective valve seat, and is subjected to deformation upon voltage application, which is intended to cause the assigned valve member or sealing element to be sealed and pressed onto its respective valve seat. 【0046】 As can be further inferred from the illustration in Figure 4, the passage plate 5 is, quite exemplarily, permeated by four coupling passages 43 to 46 in general, and it is intended that these coupling passages can be coupled in various configurations to the respective first valve connection 20 and second valve connection 21 of the assigned valve assembly 18, as well as to the respective supply connection 31 of the respective valve assembly 18. From the illustration in Figure 4, it can be seen that the four passage openings 14 in total are fluidly connected to fluid connection parts, referred to as fluid connection parts 73 to 76, which are not shown in more detail, via the fluid passages 33 to 36 assigned to each of them. Furthermore, it is intended that the fluid connection parts 73 to 76 are located on the connecting surface 77 of the support plate 2. As can be seen from Figure 1, both fluid connectors 73 and 74 are located far apart from the fluid connectors 75 and 76 that are themselves assigned to their respective valve modules. For clarification of the relationship between fluid connectors 74 through 76, these fluid connectors are shown in Figure 4 within a common drawing plane. 【0047】 Exemplary, a silencer 78 is positioned at the first fluid connection 73, and therefore, the allocated first fluid passage 33 may also be referred to as an exhaust passage. A compressed air source 79 is attached at the second fluid connection 74, and therefore, the second fluid passage 34 may also be referred to as a supply passage. At the third fluid connection section 75, the first working conduit 80 of the compressed air consumption section 82 is attached, and therefore, the assigned third fluid passage 35 may also be referred to as the first working passage. At the fourth fluid connection section 76, the second working conduit 81 of the compressed air consumption section 82 is attached, and therefore, the assigned fourth fluid passage 36 may also be referred to as the second working passage. Exemplarily, the compressed air consumption unit 82 is formed as a reciprocating pneumatic cylinder and is intended to provide bidirectional linear motion. 【0048】 As shown in Figure 4, fluid passages 33 to 36 within the support plate 2 and coupling passages 43 to 46 within the passage plate 5 are adapted to each other so that, for example, compressed air supplied from a compressed air source 79 is supplied to the first coupling passage 43 through a second fluid passage 34. The passage plate 5 is formed so that compressed air from the compressed air source 79 is supplied to the supply connections 31 of both lower valve assemblies 18 located within the valve housing 6. Exemplarily, it is intended that each first valve connection of the first valve connection 20 of all valve assemblies 18 is connected to a third coupling passage 45, which in turn is connected to a third fluid passage 35 of the support plate 2 and opens to a third fluid connection 75, to which the second working conduit 81 of the compressed air consumption unit 82 is connected, as shown in Figure 4. Furthermore, a first fluid passage 33 provided for exhaust is connected to a second coupling passage 44, and this second coupling passage is intended to be connected to the supply connection portions 31 of both upper valve assemblies 18 located within the valve housing 6. Exemplarily, each second valve connection of the second valve connection 21 of all valve assemblies 18 is connected to a fourth coupling passage 46, which in turn is connected to a fourth fluid passage 36, which opens to a fourth fluid connection 76. Exemplarily, it is intended that the first working conduit 80 of the compressed air consumption unit 82 is connected to the fourth fluid connection 76. Both lower valve assemblies 18, housed within the valve housing 6 by a pre-provided fluid connection via the passage plate 5, are used for freely selectable ventilation of either the first work conduit 80 or the second work conduit 81. Both upper valve assemblies 18, housed within the valve housing 6, are used for freely selectable exhaust of either the first work conduit 80 or the second work conduit 81. 【0049】 Accordingly, the fluid connection of the four valve assemblies is configured such that the ventilation and exhaust functions for each of the two work conduits 80 and 81 can be redundantly generated by two valve assemblies 18 each, and thus, although a reduced flow rate must be tolerated, the maintenance of each ventilation or exhaust function is also guaranteed in the event of failure of one of these valve assemblies 18. 【0050】 To enable the measurement and detection of the flow process for the compressed air consumption unit 82, a throttling section 65 is provided within the third fluid passage 35, and this throttling section has a defined flow resistance. A first pressure sensor 66 and a second pressure sensor 67 are provided at the end region of each throttling section 65, and these pressure sensors are electrically coupled to the control device 63 via assigned sensor wires 86 and 87. Each of the pressure sensors 66 and 67 supplies an electrical sensor signal to the control device 63 via its assigned sensor wires 86 and 87. As a result, the control device 63 can detect the pressure difference between the first pressure sensor 66 and the second pressure sensor 67, and can determine the flow rate through the third fluid passage 35 based on the well-known flow resistance of the throttling section 65. 【0051】 Within the fourth fluid passage, a third pressure sensor 68 and a flow measuring device 69 are arranged, connected to a control device 63 via sensor wires 88 and 89, and similarly formed to provide sensor signals to the control device 63. For example, the use of the third pressure sensor 68 in combination with the flow measuring device 69 enables direct flow measurement within the fourth fluid passage 36. 【0052】 As shown in Figure 4, pressure sensors 66 to 68 are each positioned on the mounting surface 100 of the sensor plate 97 at the ends of the stub conduits 93 to 96, and within this sensor plate, the sensor wires 86 to 89, which are shown separately for illustrative purposes, are actually intended to be integrated. Depending on the usage, as shown in Figure 4, it is possible to liquid-tightly close each stub conduit 93 to 96 with the assigned pressure sensors 66 to 68, or to selectively install blind plugs into each stub conduit 93 to 96 unless any pressure measurement or other measurement (temperature measurement, humidity measurement, etc.) is provided for the third fluid passage 35 or the fourth fluid passage 36. As can be further observed from Figure 4, the mounting surface 100 of the sensor plate 97 is positioned to face the lower surface 50 of the support plate 2. 【0053】 Furthermore, a sensor wire 90 is assigned to the control device 63, and this sensor wire is equipped with a plug-in connector 91 at its end. As shown in Figure 4, a sensor cable 98 is plugged into the plug-in connector 91, and this sensor cable is used for electrical coupling between the position sensor 99 assigned to the compressed air consumption unit 82 and the control device 63. 【0054】 In various modifications of the passage plates 24 to 27, as shown in Figures 5 to 8 of these modifications, the connecting passages 43 to 46 formed within each of the passage plates 24 to 27 are provided with reference designations P for a pressure supply section, S for an exhaust section, A for a first working connection section, and B for a second working connection section, which have been more common in aerodynamics for some time. The assignment of functions for each coupling passage 43 to 46 is, accordingly, identical to the schematic illustration shown in Figure 4; however, if, for example, the silencer 78 and the compressed air source 79 are reversed in the first fluid connection 73 and the second fluid connection 74, they can be selected in a similarly different manner. 【0055】 Selectively, the second fluid connection 74, as well as the first fluid connection 73, may be intended to be fitted with a different compressed air source or another source for pressurized gas. In this way, the valve module system can be used, for example, for the delivery of a gas mixture having a variably adjustable ratio of compressed air and pressurized gas. 【0056】 Passage plates 24 to 27 are, quite exemplarily, intended for the connection of two valve assemblies 18, respectively. Depending on the respective usage, in the same manner as in Figure 4, a redundant connection of four valve assemblies 18 may be intended, in which case the connection configurations shown in each case will be redundant and, in particular, mirror-symmetrical within the respective passage plates 24 to 27. 【0057】 In the first modified example of the passage plate 24 shown in Figure 5, the supply connection portion 31 is connected to the first coupling passage 43, the second supply connection portion 31 is connected to the second coupling passage 44, both first valve connection portions 20 are connected to the third coupling passage 45, and both second valve connection portions 21 are connected to the fourth coupling passage 46. Accordingly, one valve assembly 18 is used as an exhaust valve for both coupling passages 45 and 46, while the other valve assembly 18 is used as a vent valve for both coupling passages 45 and 46. 【0058】 In the second modified example of the passage plate 25 shown in Figure 6, the supply connection portion 31 is connected to the first coupling passage 43, and the second supply connection portion 31 is connected to the second coupling passage 44. Furthermore, all valve connection portions 20 and 21 are connected to the third coupling passage 45, while the fourth coupling passage 46 has no connections whatsoever. This type of fluid connection within the passage plate 25 allows for ventilation and exhaust of a compressed air consumption unit (not shown) to be achieved with twice the volumetric flow rate, in which case the compressed air consumption unit could be, for example, an easily operating pneumatic cylinder. 【0059】 In a third modified example of the passage plate 26, as shown in Figure 7, both supply connection portions 31 are connected to the first coupling passage 43, while each first valve connection portion 20 is connected to the third coupling passage 45, and each second valve connection portion 21 is connected to the fourth coupling passage 46. By this means, for example, fluid flow control can be performed for two separate compressed air consumption units that are fluidly coupled to the third coupling passage 45 or the fourth coupling passage 46. 【0060】 In the fourth modified example of the passage plate 27 shown in Figure 8, both supply connection portions 31 are connected to the first coupling passage 43, while all valve connection portions 20, 21 are connected to the third coupling passage 45 and have no connection to the fourth coupling passage 46. By this means, for example, fluid flow control can be performed for a compressed air consumption unit having twice the flow cross-sectional area compared to the passage plate 27, as shown in Figure 7. 【0061】 In the modified mounting shown in Figure 9 for the sensor plate 97 positioned below the support plate 2, it is intended, quite exemplary, that the first stub conduit 93 is closed by a blind plug 70, and that the temperature sensor 71 is assigned to the second stub conduit 94. A pressure sensor 66 is assigned to the third stub conduit 95, and a humidity sensor 72 is assigned to the fourth stub conduit 96. 【0062】 In the modified mounting shown in Figure 10 for the sensor plate 97 positioned below the support plate 2, it is intended, quite exemplary, that the second stub conduit 94, like the first stub conduit 93, is also closed by a blind plug 70, and that the temperature sensor 71 is assigned to the third stub conduit 95 and the humidity sensor 72 to the fourth stub conduit 96. 【0063】 It is possible to assign different sensors to each of the stub conduits 93 to 96 as needed, and in that case, the issue is related to the modification of the mounting for the sensor plate 97, and it is self-evident that no other changes are necessary, especially in the support plate 2.
