Description

Die Erfindung betrifft einen Luftzuführblock für eine Webmaschine nach dem Oberbegriff von Anspruch 1.The invention relates to an air feed block for a loom according to the preamble of claim 1.

Ein Luftzuführblock der eingangs genannten Art ist aus der WO 97/29231 bekannt. Der Luftzuführblock ist zwischen einer Druckluftzuführeinrichtung und einem Paar von Hauptblasdüsen angeordnet, die einen Schußfaden in ein Webfach eintragen. Der bekannte Luftzuführblock enthält einen an die Druckluftzufuhr angeschlossenen Eingang und einen an das Paar Hauptblasdüsen angeschlossenen Ausgang. Eingang und Ausgang sind mittels im Luftzuführblock vorhandenen Kanälen miteinander verbunden, wobei in den Luftzuführblock ein schaltbares Schließventil und ein einstellbares Drosselventil integriert sind. Wenn eine Webmaschine eine größere Anzahl unterschiedlicher Schußfäden verarbeiten soll, so ist eine entsprechend große Anzahl von Paaren von Hauptblasdüsen und auch eine entsprechend große Anzahl an Luftzuführblöcken erforderlich.An air supply block of the type mentioned is from the WO 97/29231 known. The air supply block is disposed between a compressed air supply means and a pair of main blowing nozzles which insert a weft yarn into a shed. The known air supply block includes an input connected to the compressed air supply and an output connected to the pair of main blowing nozzles. The input and output are connected to each other by means of existing channels in the air supply block, wherein in the air supply block, a switchable closing valve and an adjustable throttle valve are integrated. If a weaving machine is to process a larger number of different weft threads, then a correspondingly large number of pairs of main blowing nozzles and also a correspondingly large number of air feed blocks are required.

Der Erfindung liegt die Aufgabe zugrunde, einen Luftzuführblock der eingangs genannten Art so auszubilden, daß relativ viele Hauptblasdüsen mit Druckluft versorgt werden können, ohne daß für die Druckluftversorgung ein sehr großer Bauraum erforderlich ist.The invention has for its object to form a Luftzuführblock of the type mentioned so that a relatively large number of Hauptblasdüsen can be supplied with compressed air without a very large space is required for the compressed air supply.

Diese Aufgabe wird dadurch gelöst, daß an einer Längsseite eines im wesentlichen quaderförmigen Grundkörpers zwei Ausgänge vorgesehen sind, denen jeweils eigene schaltbare und einstellbare Ventile zugeordnet sind.This object is achieved in that two outputs are provided on a longitudinal side of a substantially cuboid base body, each of which own switchable and adjustable valves are assigned.

Die Erfindung bietet den Vorteil, daß mittels eines Luftzuführblockes zwei Sätze von Hauptblasdüsen mit Druckluft versorgbar sind, so daß der benötigte Bauraum relativ gering ist. Derartige Luftzuführblöcke eignen sich besonders gut für die Verwendung in Luftdüsenwebmaschinen, bei denen mehrere unterschiedliche Schußfäden verarbeitet werden.The invention offers the advantage that two sets of main blowing nozzles can be supplied with compressed air by means of an air feed block, so that the required space is relatively low. Such Luftzuführblöcke are particularly well suited for use in air jet looms, in which several different weft threads are processed.

In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß der Grundkörper auf zwei einander gegenüberliegenden Längsseiten frei von Eingängen, Ausgängen und Ventilantrieben ist. Dadurch ist es möglich, die Luftzuführblöcke dicht nebeneinander zu montieren, so daß der Platzbedarf weiter verringert werden kann.In a further embodiment of the invention it is provided that the main body is free of inputs, outputs and valve actuators on two opposite longitudinal sides. This makes it possible to mount the Luftzuführblöcke close together, so that the space requirement can be further reduced.

In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß der oder die Eingänge, die Kanäle und die Ausgänge im wesentlichen in einer gemeinsamen Längsebene des Grundkörpers angeordnet sind. Auf diese Weise läßt sich die Breite des Grundkörpers des Luftzuführblockes in Querrichtung beschränken, so daß dann auf relativ kleinem Raum eine relativ große Anzahl derartiger Luftzuführblöcke untergebracht werden kann.In a further embodiment of the invention it is provided that the one or more inputs, the channels and the outputs are arranged substantially in a common longitudinal plane of the base body. In this way, the width of the body of the Luftzuführblockes can be limited in the transverse direction, so that then a relatively large number of such Luftzuführblöcke can be accommodated in a relatively small space.

Weitere Merkmale und Vorteile der Erfindung, insbesondere bezüglich der Unterbringung der Luftzuführblöcke auf kleinem Raum ergeben sich aus den weiteren Unteransprüchen.Further features and advantages of the invention, in particular with regard to the accommodation of the Luftzuführblöcke in a small space resulting from the other dependent claims.

Der in Fig. 1 bis 3 dargestellte Luftzuführblock 1 für eine Luftdüsenwebmaschine besitzt einen quaderförmigen Grundkörper mit rechteckigem Querschnitt, der zwei Drucklufteingänge 2 und 3 aufweist, die sich an einer Längsseite 4 befinden. Zwei Druckluftausgänge 5 und 6 befinden sich an der gegenüberliegenden Längsseite 7. Die Längsseite 4 ist bei der dargestellten Ausführungsform die Unterseite, während die Längsseite 7 die Oberseite des Luftzuführblockes 1 ist. Der Luftzuführblock 1 enthält Kanäle 8, 9 und 10, die den Eingang 2 mit dem Ausgang 5 verbinden. In entsprechender Weise verbinden Kanäle 11, 12 und 13 den Eingang 3 mit dem Ausgang 6. In der Verbindung zwischen dem Eingang 2 und dem Ausgang 5 sind ein schaltbares Schließventil 14 und ein einstellbares Drosselventil 15 angeordnet. In entsprechender Weise sind zwischen dem Eingang 3 und dem Ausgang 6 ein schaltbares Schließventil 16 und ein einstellbares Drosselventil 17 angeordnet.1 to 3 for an air jet loom has a cuboid base body with a rectangular cross-section, which has two compressed air inputs 2 and 3, which are located on a longitudinal side 4. Two compressed air exits 5 and 6 are located on the opposite longitudinal side 7. The longitudinal side 4 is in the illustrated embodiment, the bottom, while the longitudinal side 7 is the top of the air supply block 1. The air supply block 1 contains channels 8, 9 and 10, which connect the input 2 to the output 5. Similarly, channels 11, 12 and 13 connect the input 3 to the output 6. In the connection between the input 2 and the output 5, a switchable closing valve 14 and an adjustable throttle valve 15 are arranged. In a corresponding manner, a switchable closing valve 16 and an adjustable throttle valve 17 are arranged between the input 3 and the output 6.

Die beiden Eingänge 2 und 3, die beiden Ausgänge 5 und 6 sowie die Kanäle 8 bis 12 sind im wesentlichen in einer Längsebene 24 des Zuführblockes 1 angeordnet. Diese Längsebene 24 verläuft lotrecht zu den genannten Längsseiten 4 und 7. Die beiden Ausgänge 5 und 6 sind in einem geringeren Abstand zueinander angeordnet als die beiden Eingänge 2 und 3. In Bezug auf eine lotrecht zu den Längsseiten 4, 7 in der Längsebene 24 verlaufende Mitte 25 liegen der Eingang 2, der Ausgang 5 und die Kanäle 8, 9 und 10 spiegelsymmetrisch zu dem Eingang 3, dem Ausgang 6 und den Kanäle 11, 11 und 13. Die Kanäle 8 bis 13 sind beispielsweise in den Luftzuführblock 1 eingearbeitete Bohrungen.The two inputs 2 and 3, the two outputs 5 and 6 and the channels 8 to 12 are arranged substantially in a longitudinal plane 24 of the feed block 1. This longitudinal plane 24 is perpendicular to the said longitudinal sides 4 and 7. The two outputs 5 and 6 are at a smaller distance With respect to a perpendicular to the longitudinal sides 4, 7 in the longitudinal plane 24 extending center 25 of the input 2, the output 5 and the channels 8, 9 and 10 are mirror-symmetrical to the input 3, the output 6 and the channels 11, 11 and 13. The channels 8 to 13, for example, in the air supply block 1 incorporated holes.

Die Ventilantriebe 20 der beiden schaltbaren Schließventile 14 und 16 befinden sich auf der Längsseite 4 des Grundkörpers zwischen den Eingängen 2 und 3. Sie befinden sich ebenfalls in der bereits erwähnten Längsebene 24 und sind ebenfalls spiegelsymmetrisch zu der Mitte 25 angeordnet.The valve drives 20 of the two switchable closing valves 14 and 16 are located on the longitudinal side 4 of the main body between the inputs 2 and 3. They are also in the already mentioned longitudinal plane 24 and are also arranged mirror-symmetrically to the center 25.

Den schaltbaren Schließventilen 14, 16 ist jeweils ein Ventilsitz 26 zugeordnet, der zu dem Kanal 9 bzw. 12 gehört. Ein Ventilstößel 18 wird mittels einer Feder 19 gegen den Ventilsitz 26 angedrückt, um die Verbindung zwischen einem Eingang 2 oder 3 und einem Ausgang 5 oder 6 abzusperren. Als Ventilantrieb 20 dient jeweils ein Elektromagnet, der dem Ventilstößel 18 zugeordnet ist und von dem Ventilsitz 26 abhebt, um das Ventil zu öffnen. Die Ventilstößel 18 der Schließventile 14 und 16 liegen jeweils in der Verlängerung des zugehörigen Ausgangs 5 und 6 und verlaufen parallel zueinander.The switchable closing valves 14, 16 are each assigned a valve seat 26 which belongs to the channel 9 or 12. A valve stem 18 is pressed against the valve seat 26 by means of a spring 19 in order to shut off the connection between an input 2 or 3 and an output 5 or 6. As the valve drive 20 is in each case an electromagnet, which is associated with the valve stem 18 and lifts off the valve seat 26 to open the valve. The valve tappets 18 of the closing valves 14 and 16 are each in the extension of the associated output 5 and 6 and parallel to each other.

Die einstellbaren Drosselventile 15 und 17 besitzen jeweils eine Spindel 21, die mittels eines Linearmotors 22 axial verstellbar ist. Das Ende 23 der Spindel 21 ragt jeweils in den zugehörigen Kanal 10 und 13. Durch die Einstellung der Position der Spindel 21 in den Kanälen 10 und 13 wird die von dem Eingang 2 zum Ausgang 5 oder von dem Eingang 3 zu dem Ausgang 6 strömende Druckluft gedrosselt, indem der Strömungsquerschnitt des jeweiligen Kanals 10 oder 13 verändert wird, wie dies in der WO 97/29231 beschrieben ist. Die Drosselventile 15 und 17 und insbesondere die Spindeln 21 liegen ebenfalls in der bereits erwähnten Längsebene 24 und sind ebenfalls spiegelsymmetrisch zueinander bezüglich der Mitte 25 angeordnet.The adjustable throttle valves 15 and 17 each have a spindle 21 which is axially adjustable by means of a linear motor 22. The end 23 of the spindle 21 protrudes into the respective channel 10 and 13. By adjusting the position of the spindle 21 in the channels 10 and 13, the compressed air flowing from the input 2 to the output 5 or from the input 3 to the output 6 throttled by the flow cross-section of the respective channel 10 or 13 is changed, as shown in the WO 97/29231 is described. The throttle valves 15 and 17 and in particular the spindles 21 are also in the already mentioned longitudinal plane 24 and are also arranged mirror-symmetrically with respect to the center 25.

An dem Gehäuse des Linearmotors 22 des Drosselventils 17 ist eine elektrische Steckverbindung 31 angeordnet. Von der Steckverbindung 31 führen elektrische Leitungen 32, 33, 34, 35 zu den Schließventilen 14, 16 und den Drosselventilen 15, 17. An die Steckverbindung 31 wird ein nicht dargestelltes elektrisches Kabel angeschlossen, das zu einer Steuereinheit der Webmaschine führt. Die Verwendung nur einer Steckverbindung 31 für beide Schließventile 14, 16 und beide Drosselventile 15, 17 ist für die Montage des Luftzuführblocks 1 zusammen mit den zugehörigen Teilen auf einer Webmaschine und für die Anbringung der erforderlichen elektrischen Anschlüsse von Vorteil. Die elektrischen Leitungen 32, 33 und 34 sind in einer Längsnut 38 verlegt, die in der die Oberseite bildenden Längsseite 7 vorgesehen ist. Die Leitungen 32 und 33 sind jeweils durch eine Bohrung 36 und 37 des Luftzuführblocks zu den Ventilantrieben 20 der Schaltventile 14, 16 geführt.On the housing of the linear motor 22 of the throttle valve 17, an electrical connector 31 is arranged. Of the connector 31 lead electrical lines 32, 33, 34, 35 to the closing valves 14, 16 and the throttle valves 15, 17. To the connector 31, a non-illustrated electrical cable is connected, which leads to a control unit of the loom. The use of only one connector 31 for both closing valves 14, 16 and both throttle valves 15, 17 is for the assembly of the air supply block 1 together with the associated parts on a loom and for the attachment of the required electrical connections of advantage. The electrical lines 32, 33 and 34 are laid in a longitudinal groove 38, which is provided in the top side forming the upper side 7. The lines 32 and 33 are each guided through a bore 36 and 37 of the air supply block to the valve actuators 20 of the switching valves 14, 16.

Wie das in Fig. 1 gezeigt ist, sind auf einem Druckluftbehälter 27 mehrere Luftzuführblöcke 1 jeweils mit Schrauben 28 befestigt. Der Druckluftbehälter 27 ist in seiner Mitte mit einer rinnenartigen Vertiefung versehen, in welche die Ventilantriebe 20 der Schaltventile 14 und 16 hineinragen. Seitlich von dieser rinnenartigen Vertiefung besitzt der Druckluftbehälter 27 mehrere Ausgänge 29, 30, an welche die Eingänge 2, 3 eines Luftzuführblocks 1 anschließen. Bei der dargestellten Ausführungsform sind vier Luftzuführblöcke 1 auf dem Druckluftbehälter 27 montiert. Die Ausgänge 29 und 30, in deren Bereich kein Luftzuführblock 1 angebracht ist, sind mit Verschlußstopfen 43 verschlossen.As shown in Fig. 1, a plurality of Luftzuführblöcke 1 are each secured with screws 28 on a compressed air tank 27. The compressed air tank 27 is provided in its center with a groove-like depression into which the valve actuators 20 of the switching valves 14 and 16 protrude. Laterally of this groove-like depression of the compressed air tank 27 has a plurality of outputs 29, 30, to which the inputs 2, 3 of an air supply block 1 connect. In the illustrated embodiment, four air supply blocks 1 are mounted on the compressed air tank 27. The outputs 29 and 30, in the area no air supply block 1 is mounted, are closed with plugs 43.

Zu den Schließventilen 14, 16 sowie zu den Drosselventilen 15, 17 sind nicht dargestellte Abdichtungsmittel vorgesehen, die ein Ausströmen von Druckluft aus dem Zuführblock 1 in diesem Bereich verhindern. Darüber hinaus sind auch Schrauben 66 vorhanden, um die Ventilantriebe 20, 22 an dem Luftzuführblock 1 zu befestigen. In den gebohrten Kanälen 8 und 11 sind an den nicht benutzten Enden Verschlußstopfen 39, 40 vorgesehen. Die Ausgänge 5, 6 sind mit nur schematisch dargestellten Anschlüssen 41, 42 versehen, die beispielsweise an den Luftzuführblock 1 angeklebt sind. Diese Anschlüsse 41, 42 dienen zum Anschluß von Leitungen, die zu einer oder einem Paar von hintereinander geschalteten Hauptblasdüsen führen. Bei einer abgewandelten Ausführungsform sind Anschlüsse 41, 42 vorgesehen, die mit Gewindeansätzen in entsprechende Gewinde der Ausgänge 5, 6 eingeschraubt sind.To the closing valves 14, 16 and to the throttle valves 15, 17 sealing means, not shown, are provided which prevent leakage of compressed air from the feed block 1 in this area. In addition, screws 66 are also provided to fasten the valve drives 20, 22 to the air supply block 1. In the drilled channels 8 and 11 are at the unused ends plugs 39, 40 are provided. The outputs 5, 6 are provided with only schematically illustrated terminals 41, 42 which are glued, for example, to the air supply block 1. These ports 41, 42 serve to connect lines which lead to one or a pair of main blowing nozzles connected in series. In a modified embodiment, terminals 41, 42 are provided, which are screwed with threaded projections in corresponding threads of the outputs 5, 6.

Mit der dargestellten Ausführungsform des Luftzuführblockes 1, bei welchem die Eingänge 2, 3, die Ausgänge 5, 6, die Kanäle 8 bis 13 und die Ventile 14 bis 17 im wesentlichen in der gleichen Längsebene 24 angeordnet sind, läßt sich ein Luftzuführblock 1 mit relativ geringer Breite B in Querrichtung schaffen, so daß eine kompakte Anordnung mehrerer derartiger Luft zuführblöcke 1 möglich ist. Bei der Verwendung üblicher Ventile und Durchmesser ist es möglich, einen Luftzuführblock 1 mit einer Breite B in der Größenordnung von 30 mm auszubilden.With the illustrated embodiment of the air supply block 1, in which the inputs 2, 3, the outputs 5, 6, the channels 8 to 13 and the valves 14 to 17 are arranged substantially in the same longitudinal plane 24, an air supply block 1 can be relative to create small width B in the transverse direction, so that a compact arrangement of several such air supply blocks 1 is possible. When using conventional valves and diameters, it is possible to form an air supply block 1 having a width B of the order of 30 mm.

Die Luftzuführblöcke 1 mit zwei Ausgängen 5, 6 und zugehörigen Ventilen sind besonders für die Verwendung bei einer Luftdüsenwebmaschine geeignet. Bei diesen Luftdüsenwebmaschinen ist es vorteilhaft, Hauptblasdüsen in gerader Anzahl vorzusehen, da der gleiche Schußfadentyp beispielsweise von zwei Spulen geliefert und somit von zwei Hauptblasdüsen oder zwei Paaren von hintereinandergeschalteten Hauptblasdüsen entsprechend der Offenbarung der WO 97/29231 in ein Webfach eingetragen wird. Falls dennoch eine ungerade Anzahl von Ausgängen gewünscht werden sollte, so ist es ohne weiteres möglich, einen der Ausgänge 5 oder 6 mit einem Verschlußstopfen zu verschließen. Selbstverständlich kann auch die Steuerung so ausgebildet werden, daß das zugehörige Schließventil 14 oder 16 ständig geschlossen bleibt.The air supply blocks 1 with two outputs 5, 6 and associated valves are particularly suitable for use with an air jet loom. In these air jet looms, it is advantageous to provide main jet nozzles in even numbers, since the same type of weft yarn is supplied, for example, by two bobbins and thus by two main blowing nozzles or two pairs of cascaded main blowing nozzles according to the disclosure of US Pat WO 97/29231 is entered in a shed. If, however, an odd number of outputs should be desired, then it is readily possible to close one of the outputs 5 or 6 with a stopper. Of course, the controller can be designed so that the associated closing valve 14 or 16 remains permanently closed.

Die Ausgänge 5 und 6 sind in einem Abstand zueinander angeordnet, der beispielsweise mit dem Abstand von Einläßen zu Hauptblasdüsen übereinstimmt, wie dies beispielsweise in der nicht vorveröffentlichten belgischen Patentanmeldung BE 9700465 korrespondierend zu WO 98/54 385 der Anmelderin offenbart ist. Damit sind die Luftzuführblöcke 1 insbesondere für die Verwendung bei Hauptdüsenvorrichtungen geeignet, wie sie in der genannten belgischen oder der internationalen Patentanmeldung offenbart sind.The outputs 5 and 6 are arranged at a distance from one another, which coincides, for example, with the distance from inlets to main blowing nozzles, as for example in the non-prepublished Belgian patent application BE 9700465 corresponding to WO 98/54385 the applicant is disclosed. Thus, the air supply blocks 1 are particularly suitable for use with main jet devices as disclosed in said Belgian or International patent application.

Bei der Ausführungsform nach Fig. 4 sind an die Ausgänge 5, 6 Bohrungen 44, 45 angeschlossen, die ihrerseits mit zur Längsseite 7 führenden Bohrungen 46, 47 verbunden sind. Die Bohrungen 44 und 46 liegen bezüglich der Mitte 25 spiegelsymmetrisch zu den Bohrungen 45 und 47. Die Enden der Bohrungen 44 und 45 sind mittels Verschlußstopfen 48, 49 verschlossen. Die Bohrungen 44 bis 47 liegen ebenfalls im wesentlichen in der Längsebene 24 des Luftzuführblocks 1. Die Bohrungen 46 und 47 sind mit Anschlüssen 50, 51 für nicht dargestellte Leitungen versehen, die beispielsweise an den Luftzuführblock 1 angeklebt sind. Über die Bohrungen 46 und 47 kann beispielsweise Druckluft mit relativ geringem Druck zugeführt werden, die dann über die Bohrungen 44 oder 45 zum Ausgang 5 oder 6 strömt. Ähnlich der Ausführungsform nach Fig. 8 kann auch an den Bohrungen 46 oder 47 ein Druckfühler angebracht werden, um den Druck der aus dem Luftzuführblock 1 strömenden Druckluft zu messen.In the embodiment of FIG. 4, bores 44, 45 are connected to the outlets 5, 6, which in turn are connected to bores 46, 47 leading to the longitudinal side 7. The holes 44 and 46 are with respect to the center 25 mirror-symmetrical to the holes 45 and 47. The ends of the holes 44 and 45 are closed by means of plugs 48, 49. The holes 44 to 47 are also located substantially in the longitudinal plane 24 of the air supply block 1. The bores 46 and 47 are provided with terminals 50, 51 for lines not shown, which are glued, for example, to the air supply block 1. For example, compressed air at relatively low pressure can be supplied via bores 46 and 47, which then flows via bores 44 or 45 to exit 5 or 6. Similar to the embodiment of FIG. 8, a pressure sensor can also be attached to the bores 46 or 47 in order to measure the pressure of the compressed air flowing out of the air supply block 1.

In Fig. 5 und 6 ist eine abgewandelte Ausführungsform ähnlich Fig. 4 dargestellt, bei welcher zu dem Ausgang 5 Bohrungen 52, 53 und 54 geführt sind, wobei die Bohrungen 52 und 53 an ihren Enden mit Verschlußstopfen 55, 56 verschlossen sind. Die Bohrungen 52, 53, 54 liegen etwas außerhalb der erwähnten Längsebene 24. Da sie jedoch relativ kleine Abmessungen aufweisen, haben sie nur wenig Einfluß auf die Gesamtbreite B des Luftzuführblocks 1. Diese Breite wird im wesentlichen durch die Ventiltriebe und/oder die Sitze 26 der Schließventile 14, 16 bestimmt.In Fig. 5 and 6, a modified embodiment similar to Fig. 4 is shown, in which to the output 5 bores 52, 53 and 54 are guided, wherein the bores 52 and 53 are closed at their ends with plugs 55, 56. The bores 52, 53, 54 are slightly outside the mentioned longitudinal plane 24. However, since they have relatively small dimensions, they have little influence on the overall width B of the air supply block 1. This width is substantially by the valve trains and / or the seats 26th the closing valves 14, 16 determines.

In Fig. 7 ist eine Ausführungsform dargestellt, die weitgehend der Ausführungsform nach Fig. 2 entspricht, so daß gleiche Teile mit den dort verwendeten Bezugsnummern verzeichnet sind. Der Luftzuführblock 1 enthält jedoch nur einen Eingang 72 für Druckluft, der in der Längsebene 24 des Luftzuführblockes 1 liegt. Dieser Eingang 72 ist an einem in einer Seitenwand der rinnenförmigen Aussparung des Druckluftbehälters 72 befindlichen Ausgang 76 angeschlossen. Der Eingang 72 ist über Kanäle 74, 8, 9 und 10 mit dem Ausgang 5 und über Kanäle 74, 8, 9 , 75, 12 und 13 mit dem Ausgang 6 verbunden. Der Kanal 75 verbindet hierbei die Kanäle 9 und 12. Der Kanal 74 verbindet den Eingang 72 mit dem Kanal 8. Das Ende des Kanals 74 ist mit einem Verschlußstopfen 77 verschlossen.In Fig. 7, an embodiment is shown, which largely corresponds to the embodiment of FIG. 2, so that the same parts are listed with the reference numbers used therein. However, the air supply block 1 contains only one input 72 for compressed air, which is located in the longitudinal plane 24 of the air supply block 1. This input 72 is connected to a located in a side wall of the channel-shaped recess of the compressed air tank 72 output 76. The input 72 is connected via channels 74, 8, 9 and 10 to the output 5 and via channels 74, 8, 9, 75, 12 and 13 to the output 6. The channel 75 in this case connects the channels 9 and 12. The channel 74 connects the input 72 with the channel 8. The end of the channel 74 is closed with a stopper 77.
