Description
Sanitärarmatur für Wasserhähne Sanitary fitting for taps
Die Erfindung bezieht sich auf eine berührungslos betätig¬ bare Sanitärarmatur mit einem Wasserauslauf, einem Misch¬ ventil und einem diesem nachgeschalteten, durch einen annäherungsempfindlichen Sensor gesteuerten Absperrventil, das durch eine mittels eines Steuergerätes in Abhängigkeit von den Steuersignalen des Sensors erregbaren mit einem Anker versehenen Magnetspule betätigbar ist.The invention relates to a contactlessly operated sanitary fitting with a water outlet, a mixing valve and a shut-off valve which is connected downstream thereof and is controlled by an proximity sensitive sensor and which is provided with an armature by a solenoid provided with an armature by means of a control device as a function of the control signals of the sensor can be actuated.
Durch die DE-OS 25 13 092 ist eine Sanitärarmatur dieser Art, die vielfach in öffentlich zugänglichen Waschräumen eingesetzt werden, um eine Betätigung eines Absperrhahnes von Hand auszuschließen, bekannt. Das in das Zulaufrohr eingesetzte Absperrventil ist hierbei als Magentventil ausgebildet und mit einem elektrischen Schaltelement als Steuergerät zusammengeschaltet, durch das bei An¬ näherung einer Person das Magnetventil geöffnet wird und somit ohne Handberührung Wasser aus dem Auslaufstück austritt. Die Versorgung des elektrischen Schaltelementes sowie des Magnetventils mit elektrischer Energie kann durch Anschließen an das allgemeine Stromnetz bewerk¬ stelligt werden.From DE-OS 25 13 092 a sanitary fitting of this type, which are often used in publicly accessible washrooms, to rule out the actuation of a shut-off valve by hand, is known. The shut-off valve inserted into the inlet pipe is designed as a magnetic valve and is connected to an electrical switching element as a control device, by means of which the magnetic valve is opened when a person approaches and water thus emerges from the outlet piece without manual contact. The electrical switching element and the solenoid valve can be supplied with electrical energy by connecting to the general power network.
./ . Abgesehen davon, daß die mittels elektrischer Anschlu߬ kabel vorzunehmenden Verbindungen leicht zu lösen sind und die Armatur somit auf sehr einfache Weise außer Betrieb zu setzen ist, wird, sobald durch den Sensor ein Impuls abgegeben und das Absperrventil geöffnet wird, dem Stromnetz elektrische Energie entnommen. Die Betriebs¬ und Wartungskosten dieser bekannten, in den meisten An¬ wendungsfällen häufig in Betrieb befindlichen Armaturen sind daher erheblich. Auch ist der Bauaufwand groß, da der Magnetspule des Absperrventils eine andere Spannung zuzu¬ führen ist als durch das Stromnetz zur Verfügung gestellt wird und mitunter aufwendige Vorkehrungen zur Vermeidung von Unfällen zu treffen sind../. Apart from the fact that the connections to be made by means of electrical connecting cables are easy to disconnect and the fitting can thus be put out of operation in a very simple manner, as soon as a pulse is emitted by the sensor and the shut-off valve is opened, electrical energy is taken from the power supply system . The operating and maintenance costs of these known fittings, which are frequently in operation in most applications, are therefore considerable. The construction effort is also great since the solenoid of the shut-off valve is to be supplied with a different voltage than is made available by the power supply and sometimes complex measures have to be taken to avoid accidents.
Aufgabe der Erfindung ist es daher, die Sanitärarmatur der vorgenannten Gattung in der Weise auszubilden, daß diese nahezu wartungsfrei arbeiten und keine Betriebs¬ kosten entstehen und daß mutwillige Beschädigungen durch Dritte weitgehend ausgeschlossen sind. Vor allem soll kein Anschluß an ein Stromnetz erforderlich, aber dennoch eine zuverlässige Betriebsweise sichergestellt sein. Auch soll trotz geringen baulichen Aufwandes eine Uπfallgefahr durch elektrischen Strom ausgeschlossen sein.The object of the invention is therefore to design the sanitary fitting of the aforementioned type in such a way that it works almost maintenance-free and there are no operating costs and that deliberate damage by third parties is largely excluded. Above all, no connection to a power grid should be required, but reliable operation should nevertheless be ensured. In spite of the low construction effort, a risk of accident by electrical current should also be excluded.
Gemäß der Erfindung wird dies dadurch erreicht, daß zur Stromversorgung der Magnetspule des Absperrventils sowie des Steuergerätes dieses unmittelbar oder über einen in die Sanitärarmatur integrierten Akkumulator oder eine Batterie an eine oder mehrere Solarzellen angeschlos¬ sen ist.According to the invention, this is achieved by connecting the solenoid of the shut-off valve and the control unit directly or via an accumulator or a battery integrated in the sanitary fitting to one or more solar cells.
Angebracht ist es hierbei, die Solarzellen unmittelbar in den Waserauslauf, beispielsweise einen Wasserhahn, auf einer oder mehreren Außenseiten einzusetzen, vorzugsweise auf dessen vertikal nach oben gerichteten AußenseiteIt is appropriate here to insert the solar cells directly into the water outlet, for example a water tap, on one or more outer sides, preferably on the outer side thereof pointing vertically upwards
• /. anzuordnen. Selbstverständlich können die Solarzellen aber auch außerhalb der Sanitärarmatur an einer licht¬ intensiven Stelle angeordnet werden.• /. to arrange. Of course, the solar cells can also be arranged outside the sanitary fitting at a light-intensive point.
Damit das Absperrventil mit einem sehr schwachen durch Solarzellen erzeugbaren Strom betrieben werden kann, ist es angebracht, dieses in der Weise auszubilden, daß dieses einen zwischen dessen Zuleitung und dessen Ableitung eingesetzten, beidseitig von dem zuströmenden Wasser be¬ aufschlagbaren Ventilkörper, beispielsweise in Form einer im Randbereich eingespannten und mit eirier durchströmbaren Öffnung versehenen Rollmembran aufweist, deren Hubbewe¬ gungen durch ein mit einer durch den Ventilkörper, vorzugs¬ weise zentrisch hindurchgeführten Zweigleitung zusammen¬ wirkenden und durch den Anker der Magnetspule beeinflu߬ barem nach Art einer Dichtung ausgebildeten Steuerglied auslösbar sind, wobei in der Magnetspule des Absperr¬ ventils ein mit einem Permanentmagneten zusammenwirkender Polkern ortsfest angeordnet sein sollte, an dem der Anker über eine Feder abgestützt ist.So that the shut-off valve can be operated with a very weak current that can be generated by solar cells, it is appropriate to design it in such a way that it has a valve body inserted between its supply line and its discharge line, which can be acted upon on both sides by the inflowing water, for example in the form of a valve body has in the edge region clamped and provided with an air-flowable opening, the stroke movements of which can be triggered by a control element which acts in the manner of a seal and cooperates with a branch line which is passed through the valve body, preferably centrally, and which can be influenced by the armature of the solenoid , wherein in the magnetic coil of the shut-off valve a pole core interacting with a permanent magnet should be arranged in a fixed position, on which the armature is supported by a spring.
Zweckmäßig ist es ferner, das Steurgerät als inrgrierte Schaltung zu gestalten, in die mittels eines in den Wasser¬ auslauf eingebauten Schalters eingegriffen werden *kann.It is also expedient to design the control device as an integrated circuit which can be intervened * by means of a switch built into the water outlet.
Werden bei einer Sanitärarmatur der vorgenannten Art gemäß der Erfindung zur Stromversorgung an das Steuer¬ gerät Solarzellen unmittelbar oder über einen in die Sanitärarmatur integrierter Akkumulator angeschlossen, so ist es möglich, die Sanitärarmatur unabhängig von einem Stromnetz zu betreiben. Dadurch wird nicht nur deren Einsatzbereich erweitert, da diese auch an Stellen angeordnet werden kann, denen nur unter Schwierigkeiten elektrische Energie aus einem Strom¬ netz zuzuführen ist, sondern es wird mit hoher Wahr¬ scheinlichkeit auch ausgeschlossen, daß auf einfacheIf in a sanitary fitting of the aforementioned type according to the invention for the power supply to the control device solar cells are connected directly or via an accumulator integrated in the sanitary fitting, it is possible to operate the sanitary fitting independently of a power supply. This not only expands their field of application, since it can also be arranged at locations to which electrical energy can be supplied only with difficulty from a power supply network, but it is also highly unlikely that there will be any problems in simple
• / . Weise mutwillige Beschädigungen vorzunehmen sind. Irgend¬ welche Verbindungskabel, die leicht durchtrennt werden können, sind nämlich nicht mehr vorhanden, die vorschlags¬ gemäß ausgebildete Saπitärarmatur arbeitet demnach nahezu wartungsfrei.• /. Wanton damage. Any connection cables that can be easily cut are no longer present, and the sanitary fitting designed according to the proposal therefore operates almost maintenance-free.
Des weiteren ist von Vorteil, daß dem Stromnetz zum Be¬ trieb der Armatur keine elektrische Energie zu entnehmen ist, diese versorgt sich vielmehr gewissermaßen selbst, in dem Lichtenergie in elektrische Energie umgewandelt und in dem Akkumulator gespeichert wird. Betriebskosten fallen demnach nicht an. Und da der Akkumulator auf die Betriebsspannung der Magnetspule des Absperrventils ausge¬ legt werden kann, sind durch die gegebene elektrische Spannung bedingte Unfälle, ohne daß besondere Vorkehrungen zu treffen sind, auch bei unsachgemäßer Behandlung ausge¬ schlossen, des weiteren ist eine Transformation der elektrischen Energie nicht erforderlich. Bei geringem Bauaufwand ist somit ein vielseitiger stöungsfreier Ein¬ satz der vorschlagsgemäß ausgebildeten Sanitärarmatur gegeben.A further advantage is that no electrical energy can be drawn from the power supply for operating the fitting, it rather supplies itself to a certain extent by converting light energy into electrical energy and storing it in the accumulator. Accordingly, there are no operating costs. And since the accumulator can be designed for the operating voltage of the solenoid of the shut-off valve, accidents caused by the given electrical voltage can be ruled out, even without improper handling, without special precautions, and furthermore a transformation of the electrical energy is possible not mandatory. A versatile, trouble-free use of the sanitary fitting designed according to the proposal is thus possible with little construction effort.
In der Zeichnung ist ein Ausführungsbeispiel der gemäß der Erfindung ausgebildeten Saπitärarmatur dargestellt, das nachfolgend im einzelnen erläutert ist. Hierbei zeigt:In the drawing, an embodiment of the sanitary fitting designed according to the invention is shown, which is explained in detail below. Here shows:
Figur 1 den Aufbau der Sanitärarmaturen in schematischer Darstellung,FIG. 1 shows the structure of the sanitary fittings in a schematic representation,
Figur 2 den Wasserhahn nach Figur 1 mit in diesen eingesetzten Solarzellen in vergrößerter Darstellung undFigure 2 shows the faucet of Figure 1 with solar cells used in this in an enlarged view and
Figur 3 einen Axialschnitt durch das bei dem Wasser- hahn nach Figur 1 vorgesehenen Abperrventil. Die in Figur 1 dargestellte und mit 1 bezeichnete Sani¬ tärarmatur weist ein Mischventil 11 sowie ein diesem nachgeschaltetes Absperrventil 12 auf, das mittels eines Sensors 13, ohne daß eine Berührung der Sanitärarmatur 1 erforderlich ist, steuerbar ist. Das aus einer Kaltwasser¬ leitung 2 und einer Warmwasserleitung 3 über Leitungen 4 und 5 dem Mischventil 11 zugeführte Wasser wird in diesen entsprechend der eingestellten Wasserverteilung gemischt und kann aus einem über einem Waschbecken 10 angeordneten als Wasserhahn ausgebildeten Wasserauslauf 7, dem das gemischte Wasser über eine Wasserleitung 6' zugeführt wird, ausströmen, sobald das über eine Leitung 6 mit dem Mischventil 11 verbundene Absperrventil 12 in Abhängigkeit von einem von dem Sensor 13 abgegebenen Impuls geöffnet wird3 shows an axial section through the shut-off valve provided in the water tap according to FIG. The sanitary fitting shown in FIG. 1 and designated 1 has a mixing valve 11 and a shut-off valve 12 connected downstream thereof, which can be controlled by means of a sensor 13 without touching the sanitary fitting 1. The water supplied to the mixing valve 11 from a cold water line 2 and a hot water line 3 via lines 4 and 5 is mixed in this in accordance with the water distribution set and can be arranged from a water outlet 7 arranged above a wash basin 10 and designed as a tap, to which the mixed water can be fed via a Water line 6 'is supplied, flow out as soon as the shut-off valve 12 connected to the mixing valve 11 via a line 6 is opened as a function of a pulse emitted by the sensor 13
Das in Figur 3 im Schnitt dargestellte Absperrventil 12 weist eine mit Stromanschlüssen 42 versehene Magnetspule 41 sowie einen in diese eingesetzten "verstellbaren Anker 47 auf, an dem ein Steuerglied 48 in Form einer Dichtung befestigt ist. Bei einer Erregung der Magnetspule 41 wird der Anker 47 entgegen der Kraft einer auf diesen einwir¬ kenden Feder 53 verstellt und an einen in der Magnetspule 41 des weiteren angeordneten Polkerπ 50 angelegt, der dazu mit einem Permanentmagneten 51 versehen ist, so daß das Absperrventil 12 geöffnet und das in dem Mischventil 11 aus kaltem und warmem Wasser entsprechend gemischte Wasser über die Wasserablaufleitung 6' dem Wasseraus¬ lauf 7 zuströmen kann.The cut-off valve 12 shown in section in FIG. 3 has a magnet coil 41 provided with current connections 42 and an " adjustable armature 47 inserted therein, to which a control element 48 is fastened in the form of a seal. When the magnet coil 41 is excited, the armature 47 becomes adjusted against the force of a spring 53 acting on it and applied to a further arranged in the magnet coil 41 Polkerπ 50, which is provided with a permanent magnet 51, so that the shut-off valve 12 is opened and that in the mixing valve 11 from cold and warm water corresponding to mixed water can flow to the water outlet 7 via the water outlet line 6 '.
Zur gesteuerten Erregung der Magnetspule 41 des Absperr¬ ventils 12 in Abhängigkeit von den Impulsen des Sensors 13 dient ein als integrierte Schaltung , in die mittels eines an dem Wasserauslauf 7 angebrachten Schalters 9 eingegriffen werden kann, ausgebildetes Steuergerät 14, das über eine Signalleitung 15 mit dem Sensor 13 und eine weitere Leitung 16 mit der Magnetspule 41 verbunden ist. Außerdem ist an das Steuergerät 14 zu dessen Ver¬ sorgung mit elektrischer Energie sowie zur Versorgung der Magnetspule 41 ein als aufladbare Batterie ausgebil¬ deter Akkumulator 17 über eine Leitung 18 angeschlossen.For the controlled excitation of the magnetic coil 41 of the shut-off valve 12 as a function of the pulses from the sensor 13, a control device 14, which is designed as an integrated circuit and can be accessed by means of a switch 9 attached to the water outlet 7, is used, which also has a signal line 15 the sensor 13 and another line 16 connected to the magnetic coil 41 is. In addition, an accumulator 17 designed as a rechargeable battery is connected via a line 18 to the control device 14 for supplying it with electrical energy and for supplying the magnetic coil 41.
Mittels des Steuergerätes 14 wird somit die Wasserzufuhr zu dem Wasserhahn 7 gesteuert und diesem wird entsprechend der Einstellung des Mischveπtils 11 aus kaltem und warmem Wasser gemischtes Wasser zugeführt.The water supply to the tap 7 is thus controlled by means of the control device 14 and this is supplied with mixed water from cold and warm water in accordance with the setting of the mixing valve 11.
Um den Akkumulator 17 unabhängig von einem Stromnetz auf- laden und somit mit elektrischer Energie versorgen bzw. das Steuergerät 14 betreiben zu können, sind, wie dies insbesondere der Figur 2 zu entnehmen ist, in den Wasser¬ hahn 7, vorzugsweise auf dessen oberer Außenseite 8 ein¬ gesetzte Solarzellen 21 vorgesehen, die über eine Leitung 22 mit dem Akkumulator 17 verbunden sind. Gemäß der strichpunktierten Darstellung in Figur 1 können Solar¬ zellen 23 aber auch an einer anderen lichtintensiven Stelle angeordnet und über eine Leitung 24 an den Akkumu¬ lator 17 angeschlossen werden. Die mittels der Solarzellen 21 bzw. 23 umgewandelte elektrische Energie wird in dem Akkumulator 17 gespeichert und bei Bedarf über die Leitung 18 dem in Figur 1 schematisch eingezeichneten Steuergerät 14 zugeführt. Die Sanitärarmatur 1 ist demnach unabhängig von einem Stromnetz stets betriebsbereit und arbeitet nahezu wartungsfrei.In order to be able to charge the accumulator 17 independently of a power supply and thus to supply it with electrical energy or to be able to operate the control device 14, as can be seen in particular in FIG. 2, the tap 7 is preferably located on the upper outside thereof 8 inserted solar cells 21 are provided which are connected to the accumulator 17 via a line 22. According to the dash-dotted illustration in FIG. 1, solar cells 23 can also be arranged at another light-intensive point and connected to the accumulator 17 via a line 24. The electrical energy converted by means of the solar cells 21 or 23 is stored in the accumulator 17 and, if necessary, fed via the line 18 to the control device 14 shown schematically in FIG. The sanitary fitting 1 is therefore always ready for operation regardless of a power supply and works almost maintenance-free.
Das Absperrventil 12 ist, wie dies im einzelnen der Figur 3 zu entnehmen ist, in einem Gehäuse 31 eingebaut und besteht aus einem verstellbaren Ventilkörper 35 in Form einer Rollmembran 36, die in ihrem äußeren Randbe¬ reich mit Hilfe zweier Spannringe 33 und 33' zwischen diesen und einem Träger 32 eingespannt ist. Der Spannring 33 ist hierbei mittels Schrauben 34 mit dem Träger 33 fest verbunden. Die Rollmembran 36 liegt bei geschlossenem Absperrventil auf einer Ventilfläche 37 auf und ist mit einem Einsatzstück 38 versehen, das eine Öffnung 39 auf¬ weist. Der Ventilkörper 35 ist somit beidseitig von dem über die Zuleitung 6 zuströmenden sich in den Räumen A und B befindlichen Wasser beaufschlagt.The shut-off valve 12, as can be seen in detail in FIG. 3, is installed in a housing 31 and consists of an adjustable valve body 35 in the form of a rolling membrane 36, which is located in its outer edge region with the aid of two clamping rings 33 and 33 ' this and a support 32 is clamped. The clamping ring 33 is in this case by means of screws 34 with the carrier 33 firmly connected. When the shut-off valve is closed, the rolling membrane 36 rests on a valve surface 37 and is provided with an insert 38 which has an opening 39. The valve body 35 is thus acted upon on both sides by the water flowing in via the supply line 6 and located in the rooms A and B.
Die Magnetspule 41 des Absperrventils 12 ist auf einem Rohr 43 gehalten, das einen Bund 44 aufweist. Mit Hilfe einer Platte 45 und Schrauben 46 ist der Bund 43 zwischen dem Träger 33 und der Platte 45 eingespannt, außerdem ist der Spalt zwischen diesen durch eine Dichtung 44 abge¬ dichtet.The solenoid 41 of the shut-off valve 12 is held on a tube 43 which has a collar 44. The collar 43 is clamped between the carrier 33 and the plate 45 with the aid of a plate 45 and screws 46, and the gap between them is sealed by a seal 44.
Der Polkern 50 ist mit dem Rohr 43 durch eine Schweißnaht 54 fest verbunden und somit ortsfest angeordnet, außerdem ist der Polkern 50 mit einem Außengewinde 56 ausgestattet, auf das eine Mutter 55 aufschraubbar ist. Die Magnetspule 41 kann somit fest auf dem Rohr 43 aufgespannt werden.The pole core 50 is fixedly connected to the tube 43 by means of a weld seam 54 and is thus arranged in a stationary manner. In addition, the pole core 50 is equipped with an external thread 56 onto which a nut 55 can be screwed. The magnetic coil 41 can thus be clamped firmly on the tube 43.
Wird bei geschlossenem Absperrventil 12, wie dies in Figur 3 dargestellt ist, die Magnetspule 41 erregt, so wird der Anker 47 entgegen der Kraft der in einer Bohrung 52 eingesetzten Feder 53 in Richtung des Polkernes 50 ver¬ schoben und wird an diesem durch die Kraft des Permanent¬ magneten 51 festgehalten. Das zwischen dem Polkern 50 und dem Anker 47 befindliche Wasser wird bei dieser Verstellbewegung über einen in diesen und das Steuerglied 48 eingearbeiteten Schlitz 49 herausgedrückt. Die Strom¬ zuführung der Magnetspule 41 ist somit nur kurzzeitig bis zur Anlage des Ankers 47 an dem Polkern 50 aufrecht¬ zuerhalten.If the solenoid 41 is energized when the shut-off valve 12 is closed, as shown in FIG. 3, the armature 47 is displaced in the direction of the pole core 50 against the force of the spring 53 inserted in a bore 52 and is pushed there by the force of the permanent magnet 51 held. The water located between the pole core 50 and the armature 47 is pressed out during this adjustment movement via a slot 49 incorporated therein and the control member 48. The current supply of the magnetic coil 41 can thus only be maintained for a short time until the armature 47 abuts the pole core 50.
Durch die Verstellbewegung des Ankers 47 und des mit diesem verbundenen Steuergliedes 48 wurde eine Zweigleitung 62 geöffnet, die durch einen an dem Ventilkörper 35 angeformten Ansatz 61 hindurchgeführt ist. Dadurch wurde, da das Steuerglied 48 von der Mündung 63 des Ansatzes 61 abgehoben wurde, der Raum B entlastet, das Wasser kann somit aus diesem über die Zweigleitung 62 in die Ablaufleitung 61 abströmen. Dies bewirkt, daß durch den in dem Raum A herrschenden Druck die Roll¬ membran 36 im mittleren Bereich durchgebogen und der Ventilkörper 35 von der Ventilfläche 37 abgehoben wird, das Wasser kann somit in ausreichender Menge unmittelbar von der Zuleitung 6 in die Ablaufleitung 61 gelangen.The adjustment movement of the armature 47 and the control element 48 connected to it made a branch line 62 opened, which is passed through a projection 61 formed on the valve body 35. As a result, since the control element 48 was lifted from the mouth 63 of the extension 61, the space B was relieved, and the water can thus flow out of it via the branch line 62 into the drain line 6 1 . This causes the rolling membrane 36 to be bent in the central region and the valve body 35 to be lifted off the valve surface 37 due to the pressure prevailing in the space A. The water can thus pass directly from the feed line 6 into the drain line 6 1 in sufficient quantity .
Soll das Absperrventil 12 wiederum geschlossen werden, weil beispielsweise durch den Sensor 13 signalisiert wird, daß sich keine Person mehr in dessen Einflußbereich befindet, so ist der Magnetspule 41 über das Steuer¬ gerät 14 lediglich ein umgepolter Stromstoß zuzuleiten. Dadurch wird die Magnetkraft des Permanentmagneten 51 aufgehoben und durch die Kraft der Feder 53 wird das Steuerglied 48 gegen die Mündung 63 des Ansatzes 61 gedrückt. Sobald die Zweigleitung 62 somit verschlossen ist, baut sich in dem Raum B der gleiche Druck auf wie in dem Raum A. Und da die jeweils von Wasser beaufschlagten Flächen unterschiedlich groß bemessen sind, wird der Ventilkörper 35 wiederum auf die Ventilfläche 37 gepreßt, das Absperrventil 12 ist geschlossen. Zum Öffnen undIf the shut-off valve 12 is to be closed again because, for example, the sensor 13 signals that there is no longer any person in its area of influence, the solenoid 41 is only to be supplied with a reversed current surge via the control device 14. As a result, the magnetic force of the permanent magnet 51 is canceled and by the force of the spring 53, the control member 48 is pressed against the mouth 63 of the extension 61. As soon as the branch line 62 is thus closed, the same pressure builds up in the room B as in the room A. And since the areas acted upon by water are of different sizes, the valve body 35 is in turn pressed onto the valve area 37, the shut-off valve 12 is closed. To open and
Schließen des Absperrventils 12, d. h. zur Stromversorgung der Magπetspule 41 ist dieser demnach nur kurzzeitig ein Strom mit geringer Stärke zuzuleiten, der mit Hilfe der Solarzellen 21 bzw. 23 durch Umwandlung von Lichtenergie in elektrische Energie gewonnen werden kann.Closing the shut-off valve 12, d. H. for the power supply of the magnetic coil 41, it is therefore only to be supplied with a current of low intensity for a short time, which current can be obtained with the help of the solar cells 21 or 23 by converting light energy into electrical energy.
Mittels einer Haube 40, die durch eine in ein Innenge¬ winde 58 des Polkernes 50 eingreifenden Schraube 57 ge¬ halten ist, ist die Magnetspule 41 des Absperrventils 12 abgedeckt. The solenoid 41 of the shut-off valve 12 is covered by a hood 40 which is held by a screw 57 which engages in an internal thread 58 of the pole core 50.
