Description

The invention relates to a valve carrier of a valve arrangement, comprising a valve carrier strip extending in a longitudinal direction in which at least two main fluid channel systems are formed, each comprising a main fluid channel passing through the valve carrier strip in the longitudinal direction and a plurality of branch fluid channels branching away from the main fluid channel at a distance from each other, the valve carrier strip being alongside on the outside has a mounting surface, which is divided into a plurality of consecutively in the longitudinal direction, provided for equipping with valve units placement locations, each of which opens a branch fluid channel of each main fluid channel system.

The invention further relates to a valve arrangement equipped with such a valve carrier and a method for producing the valve carrier.

From the EP 2 047 111 B1 It is known to provide a valve assembly with a valve carrier of the type mentioned above, which has a plate-shaped valve carrier strip, which is equipped with a plurality of successively arranged in a longitudinal direction of the valve carrier valve units. In the valve carrier strip a plurality of main fluid channel systems are formed, which serve the supply and discharge of a controllable by the valve units fluidic pressure medium. Each main fluid channel system has a main fluid passage extending longitudinally through the valve carrier bar and a plurality of branch fluid passages branching from the main fluid passage leading to discrete areas of a mounting surface of the valve carrier bar which serve as placement locations at which the valve units are mounted. The valve carrier strip is a one-piece body, which is manufactured depending on the application in the desired length and width. Alternatively, to allow for a simple variation in the length of the valve carrier, the valve carrier may have a modular construction and may be composed of valve carrier modules mounted one on the other in the longitudinal direction.

A valve arrangement with a modular design in its longitudinal direction valve carrier is also from the WO 2009/127223 A1 known.

The invention has for its object to take measures that favor the variability of the structure of a valve carrier in a simple manner.

To solve this problem, it is provided in a valve carrier of the type mentioned above, that the valve carrier strip consists of several alongside angestücketen one-piece profile bars, in each of which one of the Hauptfluidkanalsysteme is formed and together define the assembly area by each profile bar along the outside a in the Has longitudinally extending strip-shaped mounting surface portion of the mounting surface, to which the branch fluid channels of the formed in the profile bar main fluid channel system.

The object is further achieved by a valve arrangement which has a valve carrier formed in the aforementioned sense and which has a plurality of valve units, which are each mounted on one of the loading locations of the valve carrier strip of the valve carrier and which have internal valve channels which are in the Placement areas are fluidly connected to the there branching branch fluid channels of the main fluid channel systems of the valve carrier.

The object is further achieved by a method by which a valve carrier and / or a valve assembly of the structure defined above is produced and which is characterized in that the profile bars are cut to length in the appropriate length for the valve carrier bar of a rod-shaped starting material, the internal Having output channel structure, which corresponds in nature to a Hauptfluidkanalsystem, whereupon the profile bars to form the valve carrier strip are attached alongside each other.

The inventively designed and manufactured valve carrier has a modular valve carrier strip, wherein the modularity is present in a direction perpendicular to the longitudinal direction of the valve carrier transverse direction. The valve carrier strip is composed of a plurality of one-piece profiled bars, which are attached to each other alongside each other and together define the assembly area provided for equipping with valve units. The placement surface is composed of several juxtaposed transverse to the longitudinal direction mounting surface sections, which have a strip-like shape and are each formed by a strip-shaped outer surface portion of the profile bar in question. Each profile bar is formed in the interior with one of the several main fluid channel systems, the branch fluid channels of which open out to form the strip-shaped component surface area formed on the relevant profile bar. In the juxtaposed state of the profile bars, the centers of the main fluid channels of the individual main fluid channel systems are expediently located in a common plane. The profile bars are easy to manufacture and can be tailored to the desired length for the valve carrier strip length of a rod-shaped starting material with simple manufacturing technology. The modular structure favors a decentralized production of valve carriers, Bar-shaped starting material is very easy to transport to different production sites, where the individual desired blanks can be made without special manufacturing knowledge. According to the selected number of profile bars valve carrier strips for valve assemblies of different types can be made, which differ in particular in the functionality of the valve units from each other. For example, a valve support bar can be composed of two adjoining profile bars when a valve carrier bar equipped with two main fluid channel systems is required. This is particularly the case when the associated valve units have a 3/2-valve functionality. However, it is also possible, for example, to attach three profile bars to one another in order to obtain a valve carrier strip with three main fluid channel systems, which is advantageous in connection with valve arrangements whose valve units have a 5/2 functionality or a 5/3 functionality.

Advantageous developments of the invention will become apparent from the dependent claims.

Particularly cost-effective, the valve carrier can be realized from individual profiled bars, if exactly one of the main fluid channel systems is formed in each profile bar. In principle, however, it would be possible to form a plurality of main fluid channel systems extending alongside one another in at least one of the profile rods.

As already mentioned, the valve carrier strip can be composed of exactly two or more than two with their long sides together attached one-piece profile bars. It is therefore possible in the production of the possibility of customization of the valve support bar to the given requirements.

The distribution pattern of the channel openings of the branch fluid channels present on the strip-shaped component surface sections is preferably identical for all profile rods. In this way, there is the advantageous possibility to produce all profile bars from one and the same rod-shaped starting material.

Regardless of the identical distribution pattern of the channel mouths of the branch fluid channels, there may be an axial offset of the channel mouth rows between the individual profile rods, so that the distance from this end face to the first channel mouth of the row of channel openings in the case of the several profile rods differs starting from one end side of the profile rods. As a result, channel openings belonging to the respective same placement space lie on an oblique opening distribution line with respect to the longitudinal direction of the valve carrier. This orientation is advantageous in connection with some types of valve units. In addition, particularly compact transverse dimensions of the valve carrier strip can be realized in this way.

The described offset of the distribution patterns of the channel mouths of the individual profile bars can be realized, for example, very simply by using at least two identical profile bars which have the same distribution pattern at channel mouths of the branch fluid channels, but the distribution patterns of the channel mouths are closer to one of the two end faces of the channel openings start each profile bar and the profile bars are set with reverse longitudinal alignment to each other or are

At least one profiled bar of the plurality of profiled bars of the valve carrier strip is expediently provided with valve attachment holes which open out to its component surface section and which can be used to fix valve units arranged at the placement locations. These valve mounting holes are expediently blind hole-type threaded holes, each having an internal thread, into which a fastening screw acting on the associated valve unit can be screwed. The hole openings of the valve mounting holes are preferably regularly distributed in the longitudinal direction of the valve carrier strip such that at least one or even a plurality of valve mounting holes is or are associated with each assembly station.

In principle, a plurality of profile bars or all profile bars of the valve carrier strip can be provided with valve attachment holes. However, preference is given to an embodiment in which only one of the several integral profile bars of the valve carrier strip has the valve mounting holes. As has been proven, this is sufficient to still sufficiently tightly and fluid-tightly fix the valve units to the mounting surface.

The profile bars have each other, viewed in the longitudinal direction, expediently the same outer contour. This favors the production of all profiled bars from one and the same rod-shaped starting material. In addition, this provides the ability to attach the profile bars in any order alongside each other to produce a valve support bar.

In principle, the profile bars could at least partially have a round outer contour. However, a total of prismatic design of the profile bars is considered to be particularly advantageous, so that the longitudinal outer circumferential surface of the relevant profile bar composed of several in-plane strip-shaped outer surface sections. The existing between in the circumferential direction of the profile bar outer surface portions existing corner or edge portions may of course be rounded. Adjacent profile bars are attached to one another with strip-shaped outer surface sections facing one another, wherein a further strip-shaped outer surface section of each profile bar oriented in this respect preferably forms one of the strip-shaped loading surface sections which contribute to the formation of the assembly area.

Particularly advantageous is a rectangular outer contour of the profile bars is considered. Each profile bar is thereby formed as a square bar with possibly rounded longitudinal edges. The production of such a design is particularly simple and favors the modular combination of the profile bars with each other.

The valve carrier expediently has two end caps, which are attached to the opposite end faces of the valve carrier strip. Preferably, the profile bars are held together by the two end covers transversely to the longitudinal direction of the valve carrier. In this context, it is advantageous if the profile bars apart from the end caps have no mutual attachment. This saves additional fasteners on the profiled bars. For example, no direct screw connection between the adjacent profile bars is required.

For example, the end caps can be fixed purely frictionally to at least one and preferably to each profile bar. For example, the end cover can be plugged in front of the arrangement of profiled bars in this context or plugged into the arrangement of profiled bars frontally. There is the alternative possibility of fixing the end caps in the longitudinal direction in a form-fitting manner, for example solely by a screw connection or preferably by a latching connection, on at least one of the profile rods. This positive fastening can also be combined with a frictional connection.

In order to mechanically hold together the profiled bars which are attached to one another in a particularly simple manner for forming the valve carrier, it is advantageous if each end cap has one attachment post per profile bar, which dips into the end face of a main fluid channel of the profile bar and is radially supported within the main fluid channel on the profile bar. As a result, the profiled bars attached to one another are immovably fixed relative to one another, mediating the end covers, transversely to the longitudinal direction of the valve carrier.

The attachment stubs are preferably sleeve-shaped, which contributes to a saving of material and which also offers the possibility of using the attachment stubs for the delimitation of a cover lid passing through the cover fluid channel, which can be used or used for fluid passage through the end cap.

The attachment piece expediently carries on its outer circumference a sealing ring pressed against the inner peripheral surface of the associated main fluid channel. This results in a fluid-tight seal of the main fluid channel systems to the surrounding atmosphere in the transition region between the profiled bars and the end caps.

Preferably, at least one and preferably each of the two end covers is penetrated by at least one fluid channel designated as a cover fluid channel. Each cover fluid channel has an axial mouth facing the valve carrier strip, which is referred to as an axial inner mouth and which communicates with one of the main fluid channels. If the cover fluid channel penetrates a sleeve-shaped attachment stub, the axial inner opening is expediently located on the end face of this attachment stub. Each cover fluid channel also has an outer mouth facing away from the valve carrier strip, in particular oriented in the longitudinal direction, through which a supply and / or discharge of a fluidic pressure medium into a main fluid channel system or from a main fluid channel system can be performed. The end caps can be used in this way to the central fluid supply and / or fluid disposal with respect to the mounted on the valve carrier bar valve units.

At least one cover fluid channel has at its outer mouth expediently via a fluid line connection device or via a silencer. The installation of a silencer, in conjunction with the use of compressed air, allows for a silent discharge of the pressure medium to the atmosphere. A fluid line connection device allows a simple connection of a fluid line, for example a fluid hose, connected to an external pressure source. The fluid line connection device is expediently a plug connection piece, into which a fluid line to be connected can be plugged under sealing and preferably releasably. Alternatively, a fluid line connection device for example, be formed by a mounting thread.

It is advantageous if the valve carrier has fastening means, which are designated for better distinction as a valve carrier fastening means and which cause the end cap and the profile bars are held together firmly. Such valve carrier fastening means can in principle be designed so that they are effective directly between a cover plate and at least one profiled bar. However, an embodiment is considered more advantageous in which the valve carrier fastening means are designed to fix the valve carrier on a separate support structure, for example on a wall-like support structure, for example on a grooved plate. The valve carrier fastening means are preferably located exclusively on the two end caps and contain, for example, at least one fastening hole through which a fastening screw can be passed, with which the respective end cap can be fixed to a support structure independently of the profile rods.

It is advantageous if the valve carrier fastening means are arranged or attack exclusively on the end caps, so that the profile bars experience no direct attachment to a support structure, but are fixed or fixed exclusively to a support structure through the intermediary of the end cover.

A valve arrangement equipped with the valve carrier according to the invention has a plurality of valve units which are each designed to control the flow of a fluid and which are respectively, in particular releasably, mounted on one of the mounting locations of the valve carrier strip. Each valve unit is equipped with internal valve channels which communicate with the branching fluid channels opening out there in the area of the assigned placement space. As a result, a fluid exchange between the valve units and each main fluid channel system is possible.

Each valve unit expediently has at least one valve channel, which represents a working channel, which can be connected to a fluidic consumer to be actuated by the valve unit, in particular with a drive which can be actuated by fluid force. These working channels are preferably formed in the valve units such that they do not lead to the assembly surface, but rather to an easily accessible outer surface of the valve unit, so that a fluid line leading to a consumer can be connected directly to the respective valve unit. This offers the advantageous and preferably also used possibility of being able to dispense with working channels provided for connection to consumers in the profiled bars of the valve carrier strip.

In the manufacture of a valve carrier or valve assembly equipped with a valve assembly expediently resorted to a rod-shaped starting material, which has the outer contour of the profile bars and in the axially continuous designed as an output channel structure channel structure which corresponds in nature to a Hauptfluidkanalsystem. The rod-shaped starting material has a greater axial length than any profiled bar used to make a valve carrier bar, this starting material preferably having a multiple of the axial length of a profiled bar. From this rod-shaped starting material then length sections can be cut off, which form the profile bars. The same are then only attached to each other to form a valve carrier strip alongside each other.

From the consumer back flowing pressure medium is in each case through one of the discharge channels 8c discharged to the associated pressure sink.

All valve channels 8th open into an interior of the valve housing 4 trained valve chamber 14 in which the valve member 5 extends.

The valve carrier 2 has a longitudinal extent with a longitudinal axis 15 , whose axial direction as a longitudinal direction 15a is denoted and in the drawing by the same dashed line as the longitudinal axis 15 indicated.

The valve carrier 2 has a rigid valve carrier strip 16 , It has the same longitudinal axis 15 and longitudinal direction 15a like the valve carrier 2 all in all.

At its right angle to the longitudinal axis 15 oriented outside has the valve carrier strip 16 one preferably in one to the longitudinal axis 15 parallel plane extending assembly area 17 on. The assembly area 17 is in several in the longitudinal direction 15a successively arranged placement places 17a divided, the example without a mutual demarcation into each other and in 7 only for the sake of clarity are delimited from each other by dotted lines.

The valve carrier strip 16 is with the valve units 3 stocked. For this purpose is at each placement place 17a one of the valve units 3 with its mounting surface 13 set in advance.

The valve carrier strip 16 has one to the longitudinal axis 15 right-angled vertical axis 18 whose axial direction is a height direction 18a defined as the vertical axis 18 itself indicated by a dot-dash line. preferably defines the height direction 18a the normal direction of the assembly area 17 ,

One to the longitudinal axis 15 and to the vertical axis 18 right-angled transverse axis 22 the valve carrier strip 16 defines a width direction indicated by the same dot-and-dash line 22a the valve carrier strip 16 ,

The valve carrier strip 16 is interspersed with several fluid channel systems, each for better distinction as a Hauptfluidkanalsystem 23 be designated. The valve carrier 2 of the 1 to 7 is with three internal main fluid channel systems 23 equipped while the valve carrier 2 according to 8th via only two internal main fluid channel systems 23 features. The various main fluid channel systems 23 point inside the valve carrier strip 16 no fluidic connection with each other.

Each main fluid channel system 23 has a main fluid channel 24 that extends in the longitudinal direction 15a linear through the valve carrier strip 16 extends through. The valve carrier strip 16 has two opposite each other in the longitudinal direction 15a oriented axial faces 25 to which each main fluid channel 24 with mutually opposite Kanalendabschnitten 24a opens.

The main fluid channels 24 extend parallel to each other. Their channel centers are preferably located in a common channel center level 26 coming from the longitudinal axis 15 and from the transverse axis 22 is stretched.

From each main fluid channel 24 branches, in the longitudinal direction 15a spaced apart locations, a plurality of fluid channels, for better distinction as branch fluid channels 27 be designated. Each main fluid channel 24 forms together with its branching branch fluid channels 27 one of the main fluid channel systems 23 ,

The branch fluid channels 27 are arranged so that to each placement place 17a a branch fluid channel 27 each main fluid channel system 23 with a canal mouth 27a opens. The same to the main fluid channel system 23 belonging canal estuaries 27a the branch fluid channels 27 are in the longitudinal direction 15a aligned in a linear row. The in the longitudinal direction 15a measured distances between in the longitudinal direction 15a successive channel mouths 27a the branch fluid channels 27 are preferably identical throughout.

Thus flows to every placement place 17a a branch fluid channel 27 each main fluid channel system 23 out. Each for the same placement space 17a belonging canal estuaries 27a are in the width direction 22a spaced apart from each other and suitably lie on a common imaginary Mündungsverteillinie 28 ,

The canal mouths 27a the branch fluid channels 27 have within the respectively assigned placement place 17a such a distribution that each branch fluid channel 27 with one of the mounting surface 13 ausmündenden valve channels 8th the one on the relevant placement place 17a assembled valve unit 3 flees. This results in a paired fluid connection between the at each placement place 17a branching branch fluid channels 17 and the opposite mounting surface 13 ausmündenden valve channels 8th ,

Accordingly, each valve unit 3 in the area of the assembly area 17 with every main fluid channel system 23 fluidly connected.

One of the main fluid channel systems 23 defines a feeder system 23a and is in operation of the valve assembly 1 to the common fluid supply all on the valve carrier 2 mounted valve units 3 used. Each additional main fluid channel system 23 forms a relief channel system 23b , about all of them on the valve carrier 2 mounted valve units 3 can be relieved of pressure together or vented together. When equipped with three main fluid channel systems 23 is expediently the middle main fluid channel system 23 as a feed channel system 23a used, what on the embodiment of the 1 to 7 true.

In the valve carrier strip 16 are several valve mounting holes 32 trained to the assembly area 17 lead out and be used to the assembly area 17 attached valve units 3 independently of each other on the valve carrier strip 16 to fix. To every placement place 17a opens at least one such valve mounting hole 32 from, where by example at each placement place 17a two valve mounting holes 32 are provided.

Every valve unit 3 is in the height direction 18a of at least one fixing screw 33 interspersed, down over the mounting surface 13 protrudes and in one of the valve mounting holes 32 is fixed. The valve mounting holes 32 are expediently designed as a respective inner thread having blind hole threaded holes, in which the associated fastening screw 33 can be screwed directly. Each fixing screw 33 has a screw head 33a with which they are from above on the valve body 4 supports, so that the associated valve unit 3 with the fastening screw tightened 33 in the area of the mounting surface 13 with the assembly area 17 is tense.

The at the assembly area 17 existing hole openings 32a of the Valve fixing holes 32 So are so regular in the longitudinal direction 15a along the valve carrier strip 16 distributed that to every placement place 17a one or more valve mounting holes 32 assigned.

Between each valve unit 3 and the assembly area 17 is an at least partially rubber-elastic sealing device 34 incorporated. It causes a sealed to the environment fluid connection between the mounting surface 13 ausmündenden valve channels 8th and the branch fluid channels 27 , The one fitting place 17a associated sealing device 34 may be a contiguous sealing unit or according to the embodiments of several individual sealing elements 34a put together, each between one of the valve channels 8th and one of the branch fluid channels 27 are used.

Preferably, the sealing device 34 on the valve body 4 mounted so that it forms together with this a uniform handle assembly. The sealing device 34 acts on the assembly area 17 preferably with flat surface portions together, each one of the channel mouths 27a the branch fluid channels 27 frame.

An essential feature of the valve carrier 2 is that the valve carrier bar 16 from several side by side attached one-piece profile bars 35 consists. This results in a modular construction of the valve carrier strip 16 in a direction to the longitudinal direction 15a right-angled direction. The profile bars 35 are especially in the width direction 22a arranged side by side so that they are in a common profile level 36 lie by the longitudinal direction 15a and from the width direction 22a is stretched.

In each of the profile bars 35 is one of the main fluid channel systems 23 educated. Accordingly, each profile bar 35 in its longitudinal direction from a main fluid channel 24 interspersed and, in a transverse direction to that of the main fluid channel 24 communicating branch fluid channels 27 ,

Every profile bar 35 has a longitudinal axis 37 , where the longitudinal axes 37 the profile bars 35 parallel to each other and to the longitudinal direction 15a are aligned. Every profile bar 35 has one around the longitudinal axis 37 around outer peripheral surface 38 and lies with one in the longitudinal direction 15a over the entire length of the profile bar 35 extending strip-shaped outer peripheral surface portion 38a its outer peripheral surface 38 on an outer circumferential surface section facing it 38a every profile bar immediately adjacent to it 35 at.

The assembly area 17 the valve carrier strip 16 is in the width direction 22a alongside each other equipped component surface sections 42 together, each of an outer peripheral surface portion 38b every profile bar 35 are formed. These strip-shaped mounting surface sections 42 extend continuously between the two axial end faces 25 and lie in a common plane, which is preferably perpendicular to the vertical axis 18 runs.

Every placement place 17a is therefore made up of a longitudinal section of the component surface section 42 every profile bar 35 together.

Preferably, the number of profile bars corresponds 35 the number of main fluid channel systems 23 , It is then in every profile bar 35 exactly one of the main fluid channel systems 23 educated.

Accordingly, the valve carrier strip has 16 in the embodiment of the 1 to 7 over three profile bars 35 and in the embodiment of 8th over only two profile bars 35 ,

In principle, every profile bar 35 with to his strip-shaped assembly surface section 42 opening out valve mounting holes 32 be provided. In both embodiments, the number of valve mounting holes 32 equipped profile bars 35 but less than the total number of profile bars 35 , which contributes to a reduction in manufacturing costs. Specifically, in each case only a single profile bar is used 35 in the area of its component surface section 42 with the valve mounting holes 32 equipped, wherein it is in the embodiment of the 1 to 7 around the middle profile bar 35 is.

Preferably, that profile bar 35 with the valve mounting holes 32 equipped, whose main fluid channel system 23 as feed channel system 23a is being used.

The profile bars have one another 35 expediently the same outer contour, which in turn allows a cost-effective production, because the same starting material can be used.

It is particularly advantageous if the profile bars 35 according to the illustrated embodiments in a direction to the longitudinal direction 15a or to the axial direction of the longitudinal axis 37 considered rectangular cross section have a rectangular outer contour. With such a prismatic profiling of the profile bars 35 let yourself a valve carrier strip 16 realize, which has a plate-like, preferably flat structure. In such a case, not only the mounting surface sections are 42 just trained, but also the abutting outer peripheral surface portions 38a in the width direction 22a each directly adjacent profile bars 35 , The abutting outer surface sections 38a preferably extend in one to the mounting surface sections 42 right-angled plane.

Notwithstanding the illustrated embodiments, the profile bars 35 for example, have a different prismatic shape, for example, they have a hexagonal outer contour. The design of the profile bars 35 however, rectangular rectangular bars are considered to be particularly advantageous.

For all profiled bars 35 is expediently the distribution pattern of the strip-shaped mounting surface sections 42 outgoing channel mouths 27a the branch fluid channels 27 identical. As a result, a particularly rational production is possible.

In a preferred manufacturing process, they become the same valve support bar 16 belonging profile bars 35 obtained from one and the same type of bar-shaped starting material. This rod-shaped stock has a length equal to the length of each profile bar 35 exceeds and in particular a multiple of the length of each profile bar 35 having. This rod-shaped stock is machined to be traversed by an exit channel structure, which in nature is a major fluid channel system 23 equivalent. This means that the rod-shaped starting material is interspersed over its entire length by a rod longitudinal channel, from which a plurality of transverse channels branches off at regular intervals. To produce a profile bar, this bar-shaped starting material is cut to the desired length, wherein the cut in the respective profile bar 35 existing longitudinal portion of the rod longitudinal channel a main fluid channel 24 and those in the cut profile bar 35 existing transverse channels, the branch fluid channels 27 form.

After being cut to length from the bar-shaped starting material, the profile bars with the outer circumferential surface sections facing one another become 38a for the formation of the valve carrier strip 16 attached to each other.

Can be seen in this way valve carrier strips 16 realized with individual length and width tailored to the respective application.

The to the same valve carrier strip 16 belonging profile bars 35 have the same length among each other. They are arranged alongside one another in such a way that they are in the longitudinal direction 15a lying at the same height and pointing in the same direction faces 25a the profile bars 35 in one and the same, to the longitudinal axis 15 perpendicular plane. The lying on the same axial side faces 25a the profile bars 35 together form one of the two axial end faces 25 the valve carrier strip 16 ,

As in particular from 7 is clearly visible, there is the advantageous possibility, the distribution pattern of the strip-shaped mounting surface sections 42 existing canal estuaries 27a the branch fluid channels 27 at adjacent profile bars 35 in the longitudinal direction 15a offset form each other. This can be achieved that the Mündungsverteillinie 28 to the same placement place 17a belonging canal estuaries 27a relative to the longitudinal direction 15a runs obliquely or is inclined. This is the easiest way to realize that by the profile bars 35 so cuts off in their preparation of the rod-shaped starting material that different distances of each first channel mouth 27a the channel mouth row to each associated end face 25a of the profile bar 35 available. Sets the valve carrier bar 16 from three profiled bars 35 together, can the inclined muzzle distribution line 28 be realized very simply by the fact that the two outer profile bars 35 be arranged with rotated by 180 ° longitudinal alignment.

The valve carrier 2 contains besides the valve carrier strip 16 forming profiled bars 35 expediently also two end covers 43 , each at one of the two axial end faces of the valve carrier strip 16 or the valve carrier strip 16 forming profile bars 35 are attached. This end cover 43 expediently act as a fixing agent, which is the profile bars attached to each other alongside each other 35 in all directions transverse to the longitudinal direction 15a stick together. When the end cap 43 frontally on the profile bars 35 are mounted, there is a profiled bar end cap assembly, which is both with mounted valve units 3 as well as without assembled valve units 3 can be handled uniformly, for example, on any support structure 44 to assemble.

Exemplary is such a support structure 44 shown in the form of a support plate, wherein the design of the support structure 44 however basically is arbitrary. With the help of valve carrier fasteners 45 can the valve carrier 2 on the supporting structure 44 be attached so that not only the valve carrier 2 as such is mounted on site, but at the same time the profile bars 35 and the end covers 43 to hold the profiled bar end cap assembly firmly together.

Exemplary are the valve carrier fasteners 45 on the two end caps 43 arranged. They include, for example, one or more perforated attachment tabs 45a and also in this regard separate mounting screws 45b passing through the fastening straps 45a reach through and, for example, with the participation of sliding blocks, with the support structure 44 are screwed to the end cap 43 including that of the end covers 43 held profile bars 35 with the supporting structure 44 to tense.

To the profile bars 35 easy and effective to fix in their relative position, has each end cap 43 at its the profiled bars 35 axially facing inside 46 one of the number of profile bars 35 corresponding number of in the longitudinal direction 15a protruding attachment piece 47 on. Every attachment piece 47 is coaxial with a main fluid channel 24 of the axially opposite profile bar 35 aligned and emerges from the axial end face 25 . 25a in the associated main fluid channel 24 one. The attachment sockets 47 are with their outer contour to the inner contour of Kanalendabschnitte 24a adjusted, so that an all-round radial support between the attachment piece 47 and of the profile bars 35 formed wall of the respective associated main fluid channel 24 established.

Each main fluid channel 24 has expediently a circular cross-section. In adaptation to it also have the attachment pipe 47 a circular outer contour. In principle, however, it would be conceivable to have the cross-sectional contours of the main fluid channels 24 and the attachment socket 47 to provide with a different shape, such as oval or polygonal.

Every attachment piece 47 wearing in the region of its outer circumference expediently a sealing ring 48 , preferably as an independent component on the attachment piece 47 fitted and in a retaining groove on the outer circumference of the attachment piece 47 is fixed. Every sealing ring 48 lies on the one hand sealing on the outer circumference of the attachment piece 47 and on the other hand, on the inner periphery of the associated main fluid passage 24 on, so that a fluid outlet in the transition region between the end cap 43 and the profile bars 35 is excluded.

The end covers 43 be used for mounting on the valve carrier strip 16 with her inside 46 advance axially to the end face 25 set, with the attachment stubs 47 into the channel end sections 24a be plugged in. The end covers 43 So are in the context of a simple plug-in mounting on the valve carrier bar 16 fixable. Previously, the valve carrier bar 16 forming profile bars 35 in the desired parallel arrangement with its outer peripheral surface portions 38a attached to each other.

The mutual distances between the individual attachment stubs 47 are particularly chosen so that after their insertion into the main fluid channels 24 the profile bars 35 abut each other. The occurring mutual support between the profile bars 35 automatically causes a rotation-proof alignment of the profile bars 35 with respect to their longitudinal axes 37 , Tolerance may occur, the case that between the adjacent profile bars 35 There is a minimal gap, which is harmless in terms of mutual support, especially the profile bars 35 through the end covers 43 transverse to the longitudinal direction 15a held together.

The final assembly of the profiled bar end cap assembly is provided by the valve carrier fasteners 45 After fixing to an external support structure 44 is done. As an aside, it should be mentioned that this support structure 44 also a part of the valve carrier 2 can be.

Preferably, fixing measures are taken by which each end cap 43 regardless of the attachment to a support structure 44 in the longitudinal direction 15a immovable at the of the one-piece profile bars 35 assembled valve carrier strip 16 is fixed. This axial fixation is preferably frictional and / or positive. A positive fixation is done in particular by locking. Each end cap 43 could in principle with at least one of the profile bars 35 also screwed to a positive locking in the longitudinal direction 15a to obtain, which is not the case in the embodiment.

In the embodiment results in a frictional fixation through the in the Kanalendabschnitte 24a the main fluid channels 24 attached under radial prestressing attachment piece 47 , The radial bias results in particular from the sealing rings 48 between the outer circumference of the respective associated attachment stub 47 and the inner surface of the associated main fluid channel 24 are elastically compressed.

In principle, it would suffice the end covers 43 exclusively by this frictional connection on the valve carrier strip 16 axially fix. This fixation can then be used as a prefix until the entire profile bar end cap assembly via the end cap 43 on a supporting structure 44 is final fixed.

In the embodiment, the frictional prefixing is by a longitudinal direction 15a supports a positive engagement causing locking fixation.

A particularly advantageous type of locking is realized in the embodiment and best of the 2 . 5 and 7 seen. Here is at least one and preferably at exactly one attachment piece 47 an axially projecting latching arm 52 formed, the - in particular in the region of its free end - a radially projecting locking projection 53 has and is radially deflectable under elastic deformation. In the inner circumference of the main fluid channel 24 is a detent recess 54 introduced, in which the locking projection 53 engages when the associated attachment piece 47 in the channel end section 24a is plugged in and the associated end cap 43 on the front surfaces 25a is applied.

The insertion depth of the end cover 43 with respect to the main fluid channels 24 is suitably by a on the inside 46 the end cover 43 trained stop surface 55 limited in the on the valve carrier strip 16 assembled state of the end cover 43 on the faces facing her 25a the profile bars 35 is applied. Preferably, the stop surface 55 on a preferably plate-shaped component of a basic body 56 of the end cover 43 formed, on which also the attachment piece 47 are integrally formed.

The axial distance of the locking projection 53 from the stop surface 55 and the axial distance of the detent recess 54 from the frontal area 25 . 25a are preferably coordinated so that the end cover 43 in with the valve carrier strip 16 locked state with the face 25 the valve carrier strip 16 are axially braced.

In particular, if by locking only a prefixing of the end cover 43 should be done, it is sufficient if the associated locking means 52 . 53 . 54 only on a mounting socket 47 and in a main fluid channel 24 are formed. In the embodiment, this is the case.

The locking recesses can very easily in a single operation in the introduction of the branch fluid channels 27 be formed. For example, the branch fluid channels 27 be introduced by drilling, wherein the generation of the locking recesses 54 the hole depth is chosen so that the drilling tool through the cross section of the main fluid channel 24 passes and diametrically opposite the respective branch fluid channel 27 a blind hole-like depression in the channel wall brings in, as a detent recess 54 is usable.

Preferably, the main fluid channel 24 at least that profile bar 35 , which is for a locking fixation of a cover 43 is used, in the same distribution grid as the branch fluid channels 27 with detent recesses 54 Mistake. This will be especially good 5 clear. This eliminates the need for an individual production of the locking recesses after cutting a rod-shaped starting material to a profile bar 35 desired length.

The fastening tabs mentioned above 45a the valve carrier attachment means 45 are expediently as one-piece components of the body 56 educated.

At this point it should be mentioned that the end covers 43 preferably made of a plastic material, while the profile bars 35 are suitably made of metal and in particular of an aluminum alloy.

Preferably, at least one end cover is used 43 the supply and / or discharge of the valve units 3 to be controlled pressure medium in the valve carrier 2 and from the valve carrier 2 , This applies to the illustrated embodiments, in which even advantageously both end covers 43 have the functionality of supplying and discharging the fluidic pressure medium. The following explanations refer to both end caps 43 but you can only do it with a single end cover 43 be realized.

Each end cap 43 is, preferably in the longitudinal direction 15a , Passed by at least one fluid channel, for better distinction as a cover fluid channel 57 is designated. This cover fluid channel 57 preferably runs coaxially through one of the attachment stubs 47 through, which is sleeve-shaped in particular in this context. The cover fluid channel 57 features on the end cap 43 in the area of the inside 46 over an inner mouth 58 and in the area of the opposite outside 62 over an outer muzzle 59 , The inner muzzle 58 is from a frontal opening of the attachment piece 47 educated.

Im at the valve carrier bar 16 assembled state of the end cover 43 communicates Cover fluid channel 57 over the inner mouth 58 with one of the main fluid channels 24 ,

Preferably, the end cover 43 one of the number of main fluid channels 24 corresponding number of cover fluid channels 57 optionally, each through one of the sleeve-shaped attachment piece 47 extend through. This allows one and the same end cover 43 the fluid supply and fluid removal with respect to all main fluid channels 24 respectively.

Are both end covers 43 with a corresponding number of cover fluid channels 57 equipped, can provide fluid supply and fluid disposal from both end faces of the valve support bar 16 done here.

There is also the option of both end caps 43 each with one compared to the number of main fluid channels 24 smaller number of cover fluid channels 57 equip so that at least one main fluid channel 24 only one end face and at least one other main fluid channel 24 can be fluidly supplied or disposed of only the other end face.

The outer estuaries 59 those cover fluid channels 57 connected to the main fluid channel 24 a relief channel system 23b communicate, allow a fluid passage to the atmosphere. Preferably, the corresponding outer mouths 59 with silencers 63 stocked.

Those cover fluid channels 57 connected to the main fluid channel 24 of the feed duct system 23a communicate, point to the outside 59 expediently a fluid line connection device 64 on. It allows the particular releasable connection of a fluid line, which is connected to an external pressure source, from which the valve carrier 2 is supplied with the fluidic pressure medium to be controlled. In the fluid line connection device 64 it is in particular a connector device. Alternatively, however, a connection thread can also be provided.

It is understood that the muffler 63 can also be omitted. There is also the option of having a discharge channel 23b communicating cover fluid channels 57 also with a fluid line connection device 64 to provide a captured fluid drain from the valve carrier 2 to enable.

Both the interior estuaries 58 as well as the outer estuaries 59 are expediently to the above-mentioned body 56 arranged.

Each end cap 43 is preferably designed so that apart from the attachment stub 47 no axial overlap with the profiled bars 35 the valve carrier strip 16 is present. According to a non-illustrated embodiment, however, there is the possibility of the main body 56 in the area of the inside 46 to be provided with an axially projecting frame portion whose radial inner contour of the outer contour of the valve carrier strip 16 corresponds and defines an axially open interior, in which the valve carrier strip 16 immersed axially. The valve carrier strip 16 is then peripherally enclosed at its axial end portion of the frame portion, which is a transverse support of the end cover 43 with regard to the valve carrier strip 16 causes. The axial length of the attachment piece 47 is expediently less than that of the frame section.

Will be a fastening nozzle 47 not used for fluid management, he is not necessarily form sleeve-shaped. It can be closed at the front and made of solid material, for example.
