Abstract

The fluid dispenser has two units (2,3) able to be moved relative to each other to control a piston unit (20) and valves (13,23,45) by permanent magnets. The magnetism of the magnets brings about a return movement to the initial position. The magnets are immersed in the fluid or have the fluid flowing round them. They serve as an energy store with a magnetic field and two magnetic poles to produce magnetic force. One of them may be fixed to a base body and the other one may be movable between two stops.

At the much narrower than the housing 6 An inlet pipe or riser pipe 12 can have one end connect the other end to the bottom of the tank sucks in and that as a separate component in the nozzle 11 used or formed in one piece with the nozzle 11 is. Essentially all arrangements and components of the Discharge device lie in an axis 10, parallel to which formed the arrangements 1 to 6 elongated are.

Der Einlaßverschluß ist hier durch ein Ventil 13 gebildet, das in Abhängigkeit vom Mediendruck bzw. von den gegenseitigen Stellungen der Einheiten 2, 3 öffnet und schließt. Der innerhalb des Gehäuses 6 bewegbare Ventilkörper 14 weist eine nach innen gerichtet konische Schließfläche für den anderen Ventilkörper 15 auf, der einteilig mit dem Gehäuse 6 als in Axialansicht ringförmiger Übergang des Gehäusemantels 18 in den Stutzen 11 ausgebildet ist und so den Einlaß 9 begrenzt. Durch den äußersten Mantel 18 des Gehäuses 6 ist ein Druck- bzw. Pumpraum 16 begrenzt, welcher am inneren Ende vom Ventil 13 und am äußeren Ende von einem Kolben 19 einer Kolbeneinheit 20 bzw. von den Schließflächen eines weiteren Ventiles 23 begrenzt ist. Der Innenumfang des Mantels 18 bildet eine Laufbahn 17 zur abgedichteten Führung des Verdrängers bzw. Kolbens 19, welcher an der Laufbahn 17 nur ringlinienförmig mit nur einer oder mehreren Kolbenlippen abgedichtet geführt sein kann.The inlet closure is formed here by a valve 13, depending on the media pressure or the mutual Positions of units 2, 3 open and close. The Valve body 14 movable within the housing 6 an inwardly conical closing surface for the another valve body 15, which is integral with the housing 6 as an annular transition of the housing shell in axial view 18 is formed in the nozzle 11 and so the inlet 9th limited. Through the outermost jacket 18 of the housing 6 is a pressure or pump space 16, which is at the inner end from the valve 13 and at the outer end of a piston 19 one Piston unit 20 or from the closing surfaces of another Valves 23 is limited. The inner circumference of the jacket 18 forms a raceway 17 for the sealed guidance of the displacer or piston 19, which on the raceway 17 only ring-shaped with only one or more piston lips can be guided sealed.

Die Kolbeneinheit 20 weist einen einteilig mit dem napfförmigen Kolben 19 ausgebildeten und gegenüber diesem verengten Kolbenhals 21 auf, welcher von einem gegenüber dem Innenumfang des Kolbens 19 wesentlich verengten Längskanal 22 durchsetzt ist. Das Auslaßventil 23 weist wie das Ventil 13 zwei gegeneinander in eine Öffnungs- und eine Schließstellung bewegbare Ventilkörper 24, 25 auf, deren zusammenwirkende Schließflächen innerhalb des Kolbens 19 bzw. Kolbenhalses 21 liegen können und entweder in der Schließstellung aneinander anschlagen oder gemäß Fig. 14 Bestandteil eines Schieberventiles sind. In diesem Fall kann statt des Kolbenhalses 21 ein den Ventilkörper 25 einteilig enthaltender Kanalschaft 26 vorgesehen sein, auf welchem der Ventilkörper 24 verschiebbar und in seinen beiden Stellungen durch Anschlag o. dgl. festgelegt ist. In der Schließstellung schließt der Ventilkörper einen Querkanal 27 im Ventilkörper 25 und dieser Querkanal 27 ist mit einem Längskanal 28 leitungsverbunden. Das äußere Ende des Gehäuses 6, 18 kann mit einem gesonderten, von der Kolbeneinheit 20, 21 durchsetzten Deckel 29 verschlossen sein. Dieser Verschluß kann auch einteilig mit dem Mantel 18 ausgebildet sein.The piston unit 20 has a one-piece with the cup-shaped Piston 19 trained and narrowed relative to this Piston neck 21, which of one opposite the inner circumference of the piston 19 substantially narrowed longitudinal channel 22 is enforced. The outlet valve 23 has like the valve 13 two against each other in an open and a closed position movable valve body 24, 25, the cooperating Closing surfaces within the piston 19 or piston neck 21 can lie and either in the closed position to each other stop or part of a slide valve according to FIG. 14 are. In this case, instead of the piston neck 21 the channel body 26 containing the valve body 25 in one piece be provided on which the valve body 24 is slidable and in its two positions by stop or the like. is set. The valve body closes in the closed position a transverse channel 27 in the valve body 25 and this Cross channel 27 is line-connected to a longitudinal channel 28. The outer end of the housing 6, 18 can with a separate, cover 29 penetrated by the piston unit 20, 21 to be introverted. This closure can also be made in one piece the jacket 18 may be formed.

Gemäß den Figuren 1 und 2 sind die beiden Einheiten 2, 4 und 3, 5 ständig in Rückhubrichtung zu ihrer Ausgangsstellung durch zwei Bauteile 31, 32 mit ferromagnetischen Eigenschaften belastet, welche einander unter Magnetkraft dadurch abstoßen, daß sie mit den gleichen Magnetpolen einander zugekehrt bzw. voneinander abgekehrt sind. Die Bauteile 31, 32 können ringförmig um die Achse 10 an der Außenseite des Grundkörpers 4, 6 bzw. 5 angeordnet sein sowie gleiche Innen- und/oder Außenweite haben. Sie bewirken eine bei Annäherung, nämlich beim Arbeitshub, progressiv ansteigende Federkraft und können in der betätigten Endstellung entweder aneinander anschlagen oder mit einem Spaltabstand voneinander liegen. Sie sind hier im Bereich des Endes 8 bzw. eines Befestigungsgliedes vorgesehen, welches zur Lagesicherung der Einheit 2, 4 an dem Speicherhals dient und durch den Grundkörper 4 bzw. den Deckel 29 gebildet sein kann.According to Figures 1 and 2, the two units 2, 4 and 3, 5 constantly in the return stroke direction to their starting position by two components 31, 32 with ferromagnetic properties which loaded each other under magnetic force thereby repel that they have the same magnetic poles each other have turned or turned away from each other. The components 31, 32 can be ring-shaped around the axis 10 on the outside of the Base body 4, 6 and 5 may be arranged and the same interior and / or have outside width. They cause you to come closer, namely during the working stroke, progressively increasing spring force and can either touch each other in the actuated end position strike or be a gap apart. You are here in the area of the end 8 or a fastening member provided to secure the position of unit 2, 4 serves on the storage neck and through the base body 4 or the lid 29 can be formed.

Gemäß Fig. 3 ist das Ventil 23 mit seinen Schließflächen innerhalb des Kolbenhalses 21 und gegenüber dem Kolben 19 nach außen versetzt angeordnet. Der Ventilkörper 24 ist am Innenumfang 22 des Kolbenschaftes 21 verschiebbar geführt und begrenzt mit diesem Längskanäle, die durch Nuten im Außenumfang des Ventilkörpers 24 gebildet sein können. Der Ventilkörper 25 liegt an der Innenseite des Ventilkörpers 24 und ist in den einteiligen Kolbenbauteil 19, 21 eingesetzt oder einteilig mit diesem ausgebildet sowie von einem zentralen Längskanal durchsetzt, dessen äußeres Ende seinen Ventilsitz bildet. Auf der vom Ventilkörper 25 abgekehrten äußeren Seite des Ventilkörpers 24 liegt ein Bauteil 30 mit ferromagnetischen Eigenschaften, welcher den Ventilkörper 24 in Richtung zur Schließstellung abstößt, durch Umfangsverpressung festsitzend im Hals 21 befestigt und durchgehend von dem Kanal 28 durchsetzt ist.3, the valve 23 with its closing surfaces inside the piston neck 21 and opposite the piston 19 arranged outwards. The valve body 24 is on Inner circumference 22 of the piston skirt 21 guided and limited with this longitudinal channels by grooves in the outer circumference of the valve body 24 can be formed. The valve body 25 lies on the inside of the valve body 24 and is used in the one-piece piston component 19, 21 or formed in one piece with this and from a central Longitudinal channel penetrates, the outer end of its valve seat forms. On the outer side facing away from the valve body 25 of the valve body 24 is a component 30 with ferromagnetic Properties which the valve body 24 in the direction pushes to the closed position, stuck due to circumferential pressing fixed in the neck 21 and continuous from the channel 28 is enforced.

Wird durch Verschiebung des Kolbens 19 im Raum 16 ein Überdruck erzeugt, so wirkt dieser innerhalb des Längskanales im Ventilkörper auf die konische Kolben- und Schließfläche des unter der Magnetkraft in Schließstellung stehenden Ventilkörpers 24. Übersteigt die Druckkraft die Magnetkraft, so wird der Ventilkörper 24 in Richtung zum Bauteil 30 nach außen vom Ventilsitz abgehoben und das Medium strömt nacheinander aus dem Ventilkörper, entlang der konischen Stirnfläche des Ventilkörpers 24, durch dessen Längskanäle, in den erweiterten Raum zwischen den Körpern 24, 30, in den Kanal 28 und von dort ventilfrei bis zum Medienauslaß, an welchem es vollständig von der Austragvorrichtung 1 abgelöst wird. Der Kanal 28 ist wesentlich enger als der Raum zwischen den Körpern 24, 30. Der Ventilkörper 24 ist wie der hülsenförmige Bauteil 30 durchgehend nur aus ferromagnetischem Werkstoff hergestellt und zwischen den beiden Körpern 24, 30 befindet sich keinerlei Abschirmung o. dgl., welche die Wirkung des Magnetfeldes schwächen könnte. Auch in der öffnungsstellung wird der Körper 24 durch die Magnetkraft im Abstand vom Körper 30 gehalten. If the piston 19 is displaced in the space 16, there is an overpressure generated, this acts within the longitudinal channel in Valve body on the conical piston and closing surface of the valve body under the magnetic force in the closed position 24. If the compressive force exceeds the magnetic force, then the valve body 24 in the direction of the component 30 from the outside The valve seat is lifted and the medium flows out one after the other the valve body, along the conical face of the Valve body 24, through the longitudinal channels, in the expanded Space between the bodies 24, 30, in the channel 28 and from there valve-free up to the media outlet, at which it is complete is detached from the discharge device 1. Channel 28 is much narrower than the space between the bodies 24, 30. The valve body 24 is like the sleeve-shaped component 30 consistently made only of ferromagnetic material and there is none between the two bodies 24, 30 Shielding or the like, which affects the effect of the magnetic field could weaken. Also in the open position Body 24 by the magnetic force at a distance from body 30 held.

Die Ausbildung nach Fig. 4 ist insbesondere für sogenannte Einmal-Austragvorrichtungen geeignet, bei welchen der Kolben 19 keinen Saug- bzw. Rückhub ausführt, sondern nur in einer Richtung zu bewegen ist, da sich die gesamte gespeicherte Medienmenge von vornherein im Raum 16 befindet. Entlang der Laufbahn 17 können beabstandete Abschnitte bzw. Bauteile 31 mit ferromagnetischen Eigenschaften bzw. gleichen oder unterschiedlichen Feldstärken vorgesehen sein, zwischen welchen Abschnitte etwa gleicher Länge ohne ferromagnetische Eigenschaften vorgesehen sind. Alle Abschnitte können unmittelbar durch den einteiligen Mantel 18 gebildet sein und bis an die Lauffläche 17 reichen. In der Ausgangsstellung gemäß Fig. 4 wird der Kolben 19 durch einen Abschnitt 31 lagegesichert. Wird er dann durch manuelle Betätigung in Hubrichtung nach außen geringfügig bewegt, so wird er von diesem Abschnitt abgestoßen und vom nächsten angezogen, wodurch das Medium aus dem Raum 16 in Richtung zum Medienauslaß ausgestoßen wird. Der Kolben 19 kann dabei in einem Zug an mehreren Abschnitten 31 vorbeilaufen oder vom jeweils nachfolgenden Abschnitt 31 wieder in einer weiteren Ausgangslage gesichert werden, aus welcher er dann in der beschriebenen Weise wieder für den nächsten Hubschritt ausgelöst wird. Eine solche Anordnung ist Fig. 5 zu entnehmen.4 is particularly for so-called Disposable discharge devices are suitable, in which the piston 19 does not perform a suction or return stroke, but only in one The direction to move is because the entire stored Amount of media is in the room 16 from the outset. Along the Raceway 17 can have spaced sections or components 31 with ferromagnetic properties or the same or different field strengths can be provided between which sections about the same length without ferromagnetic Properties are provided. All sections can immediately be formed by the one-piece jacket 18 and up reach the tread 17. In the starting position according to 4, the piston 19 is secured in position by a section 31. It is then operated manually in the stroke direction slightly moved to the outside, so he is moved by this Section repelled and attracted by the next, causing the Medium ejected from space 16 towards the media outlet becomes. The piston 19 can in one go to several Pass sections 31 or from the following one Section 31 secured again in a further starting position , from which he then again in the manner described is triggered for the next lifting step. Such The arrangement is shown in Fig. 5.

Gemäß Fig. 6 sind zwei Einheiten bzw. Bauelemente gegeneinander verdrehbar und durch zwei Bauteile 31, 32 mit ferromagnetischen Eigenschaften in einer oder mehrerer gegenseitigen Drehlagen gesichert. In der gesicherten Drehlage können die beiden Bauteile 31, 32 unter der Magnetkraft vorgespannt aneinander anliegen, wenn sie mit entgegengesetzten Polen einander zugekehrt sind. Die Bauteile 31, 32 sind ringsegmentförmig und je einer der Magnete ist an einem der Grundkörper 4, 5 o. dgl. festsitzend angeordnet. Die beiden Körper 4, 5 können manuell entgegen der magnetischen Haltekraft der Bauteile 31, 32 gegeneinander verdreht und dann z.B. erst axial gegeneinander zur Durchführung des Austraghubes bewegt werden, weil eine solche Bewegung in der magnetgesicherten Stellung durch Anschlagflächen formschlüssig verhindert ist.6, two units or components are against each other rotatable and by two components 31, 32 with ferromagnetic Properties in one or more mutual Secured rotational positions. In the secured rotational position, the biased both components 31, 32 under the magnetic force abut each other when facing opposite poles are facing each other. The components 31, 32 are ring segment-shaped and one of the magnets is on one of the basic bodies 4, 5 or the like. Arrested. The two bodies 4, 5 can manually against the magnetic holding force of the Components 31, 32 rotated against each other and then e.g. first moved axially against each other to carry out the discharge stroke be because of such movement in the magnetically backed Position is positively prevented by stop surfaces.

Gemäß Fig. 7 liegt das Ventil 23 mit seinen Schließflächen außerhalb des Kolbenhalses 21 in dem demgegenüber erweiterten und an das innere Ende einteilig anschließenden Kolbenmantel. Der Ventilkörper 24 ist plattenförmig mit durchgehend konstanter Dicke, so daß eine oder beide Schließflächen durchgehend eben sein können. Während gemäß Fig. 3 der Ventilkörper 25 nicht aus ferromagnetischem Werkstoff, sondern aus einem anderen Kunststoff besteht, hat der Ventilkörper 25 gemäß Fig. 7 ferromagnetische Eigenschaften und seine Pole sind so ausgerichtet, daß er den Ventilkörper 24 zur Schließstellung belastet. Der durch Verpressung festsitzend in den Kolbenmantel eingesetzte Körper 25 kann über das innere Ende des Kolbens 19 in den Mantel 18 vorstehen und an den Raum 16 mit seinem demgegenüber verengten Längskanal unmittelbar anschließen, ohne daß er abgedichtet an der Laufbahn 17 geführt ist. Zwischen dem nutfreien Außenumfang des Ventilkörpers 24 und dem Innenumfang des Kolbenmantels ist ein ringförmiger Durchlaßkanal für das Medium frei. In der Öffnungsstellung kann der Ventilkörper 24 an Gegenanschlägen des Kolbenbauteiles 20 so anschlagen, daß der Leitungsweg in den Kanal 22 freibleibt. Sobald der Druck im Raum 16 sinkt, schließt der Ventilkörper 24 unter der Magnetkraft das Ventil 23 sofort wieder. Der Ventilkörper 24 ist nicht von Durchlässen durchsetzt.7, the valve 23 is located with its closing surfaces outside of the piston neck 21 in the opposite expanded and to the inner end integrally connected piston jacket. The valve body 24 is plate-shaped with a constant constant Thickness, so that one or both closing surfaces are continuous can be even. 3 of the valve body 25 not from ferromagnetic material, but from one other plastic, the valve body 25 has according to Fig. 7 ferromagnetic properties and its poles are like this aligned that he the valve body 24 to the closed position loaded. The one stuck in the piston skirt by pressing inserted body 25 can over the inner end of the Piston 19 protrude into the jacket 18 and to the room 16 with directly connect its narrow channel, in contrast, without being sealed on the track 17 is. Between the groove-free outer circumference of the valve body 24 and the inner circumference of the piston skirt is annular Passage channel free for the medium. In the open position the valve body 24 can on counter stops of the piston component 20 so that the route into duct 22 remains free. As soon as the pressure in room 16 drops, the closes Valve body 24 immediately under the magnetic force, the valve 23 again. The valve body 24 is not penetrated by passages.

Das Einlaßventil 13 gemäß Fig. 7 ist ähnlich dem anhand Fig. 3 beschriebenen Ventil ausgebildet. Der ringscheibenförmige Bauteil 33 mit ferromagnetischen Eigenschaften ist durch Verpressung o. dgl. festsitzend und axial anschlagbegrenzt in den Innenumfang des Mantels 18 eingesetzt. Dieser Bauteil 33 belastet den Ventilkörper 14 nach innen zur Schließstellung, da er gegenüber dem Körper 14 nach außen versetzt ist und die Körper 14, 33 mit gleichen Polen einander zugekehrt sind. Beim Rückhub der Kolbeneinheit 20 wird der Raum 16 vergrößert, dadurch im Raum 16 ein Unterdruck erzeugt und der Körper 14 in Richtung zur öffnungsstellung bzw. zum Bauteil 33 belastet, bis er vom Ventilkörper 15 abhebt. Dadurch fließt Medium aus dem Speicher durch das Ende 7 und den Einlaß 9 entlang des Außenumfanges des Körpers 14 in den Raum zwischen den Körpern 14, 33 durch die zentrale Ringöffnung des Körpers 33, so daß der Raum 16 mit Medium vollständig gefüllt wird. Mit Ende des Rückhubes schließt das Ventil 13 unter der Magnetkraft von selbst wieder. Beim nächsten darauffolgenden Arbeitshub wird das Medium in der beschriebenen Weise unter Öffnungen des Ventiles 23 aus dem Raum 16 zum Medienauslaß verdrängt.7 is similar to that with reference to FIG. 3 valve formed. The washer-shaped Component 33 with ferromagnetic properties is through Pressing or the like. Fixed and axially limited in the inner circumference of the jacket 18 used. This component 33 loads the valve body 14 inwards to the closed position, since it is offset from the body 14 and the Bodies 14, 33 with the same poles face each other. On the return stroke of the piston unit 20, the space 16 is enlarged, thereby generating a vacuum in space 16 and the Body 14 in the direction of the open position or the component 33 loaded until it lifts off the valve body 15. Thereby medium flows from the memory through the end 7 and the Inlet 9 along the outer periphery of body 14 into the room between the bodies 14, 33 through the central ring opening of the body 33 so that the space 16 with medium completely is filled. At the end of the return stroke, the valve 13 closes under the magnetic force by itself again. At the next subsequent working stroke, the medium is described in the Way under openings of the valve 23 from the space 16 to Media outlet displaced.

Fig. 9 zeigt wie die Figuren 3, 7 und 8 Differenzdruck-Ventile 13, 23, von denen das Einlaßventil 13 ähnlich demjenigen nach Fig. 7 ausgebildet ist. Der Ventilkörper 24 führt hier seine Öffnungsbewegung entgegengesetzt zu Fig. 3 nach innen gerichtet aus und der Bauteil 34 mit ferromagnetischen Eigenschaften bzw. dessen wirksamer Pol liegt gegenüber dem Ventilkörper 24 axial nach innen versetzt, so daß er in den Raum 16 frei hineinragt. Die beiden Körper 24, 34 bilden eine in sich geschlossene Kolben-Zylindereinheit mit einem stets geschlossenen und vom Medium freien, volumenveränderbaren Trocken- bzw. Druckraum, welcher von den gleichen Polseiten der beiden Magnet-Bauteile 24, 34 begrenzt ist. Der Ventilkörper 24 weist einen erweiterten Kolbenbund auf, welcher abgedichtet in einer napfförmigen Vertiefung in der äußeren Stirnseite des Bauteiles 34 gegen den Gasdruck im Trockenraum verschiebbar geführt ist. Der Bauteil 34 greift durch Verpressung o. dgl. festsitzend in den Innenumfang der Kolbenmanschette 19 ein und begrenzt mit dieser Längskanäle, welche den Raum 16 mit dem Ringraum in der Kolbenmanschette 19 ständig verbinden.9 shows, like FIGS. 3, 7 and 8, differential pressure valves 13, 23, of which the inlet valve 13 is similar to that 7 is formed. The valve body 24 leads here its opening movement opposite to Fig. 3 after directed from the inside and the component 34 with ferromagnetic Properties or its effective pole is opposite Valve body 24 offset axially inward so that it in the Room 16 protrudes freely. The two bodies 24, 34 form one self-contained piston-cylinder unit with one always closed and volume-free, free from the medium Drying or pressure room, which from the same pole sides of the two magnetic components 24, 34 is limited.

Gemäß Fig. 15 ist eine Erfassungs- bzw. Zähleinrichtung vorgesehen, welche zwei gegeneinander schrittweise weiterschaltbare Stellglieder und ggf. eine Anzeige enthält, welche ein der jeweiligen gegenseitigen Schaltstellung entsprechendes Symbol sichtbar macht. Z.B. kann eine Stellvorrichtung die Stellglieder bei jedem Arbeits- bzw. Rückhub gegeneinander um einen Schaltschritt weiterdrehen, so daß die Anzahl der durchgeführten Austraghübe erfaßt wird. Jeweils ein Stellglied ist an jedem der Grundkörper 4, 5 vorgesehen und entweder festsitzend bzw. einteilig mit diesem verbunden oder gegenüber diesem zur Durchführung der Schaltbewegung bewegbar. Die Schaltbewegung ist zweckmäßig eine Drehbewegung um die Achse 10. In Fig. 15 ist eine betätigte Endstellung der Erfassungseinrichtung 44 dargestellt, in welcher der Betätigungsnocken 36 des einen Schalt- bzw. Stellgliedes seitlich benachbart zu Betätigungsnocken 35 des anderen Stellgliedes liegt. Wird der Nocken 36 beim Rückhub nach außen bzw. oben bewegt und verdreht, so gelangt er beim nächsten Arbeitshub in die Lücke zwischen zwei benachbarten Schaltnocken 35. Die Nocken 35, 36 sind Bauteile mit ferromagnetischen Eigenschaften, so daß z.B. in der betätigten Hubendstellung der Austragvorrichtung der Bauteil 36 an einem Bauteil 35 haftet und so diese Stellung sichert, ohne daß hierfür eine federnde Rastmechanik erforderlich wäre. Aus dieser Stellung kann die Erfassungseinrichtung 44 bzw. können die Einheiten 2, 3 dann durch Aufbringen einer entsprechend großen manuellen Kraft wieder in ihre andere Endstellung überführt werden. Die Bauteile 35, 36 können aber auch in jeder Schaltstellung dafür sorgen, daß durch Magnetkraft ein Drehspiel zwischen den Stellgliedern vermieden ist. Ferner kann die Magnetkraft den Nocken 36 mit zugehörigem Stellglied in jeder Schaltstellung zur nächsten hin belasten und dadurch auch ohne gegenseitige mechanische Antriebsverbindung zwischen den Stellgliedern die schrittweise Weiterschaltung bewirken, so daß ein mechanisches Schrittschaltwerk nicht erforderlich ist.15 is a detection or counting device provided, which two incrementally incremental against each other Actuators and, if applicable, an advertisement which one corresponding to the respective mutual switching position Makes the symbol visible. For example, can be an actuator the actuators against each other during each working or return stroke turn by one switching step so that the number of the discharge strokes carried out is recorded. One each Actuator is provided on each of the base bodies 4, 5 and either fixed or connected in one piece with it or movable relative to this for performing the switching movement. The switching movement is expediently a rotary movement the axis 10. In Fig. 15 is an actuated end position of the Detection device 44 shown, in which the actuating cam 36 of a switching or actuator laterally adjacent to actuating cams 35 of the other actuator lies. If the cam 36 on the return stroke to the outside or up moved and twisted, it arrives at the next working stroke into the gap between two adjacent switch cams 35 Cams 35, 36 are components with ferromagnetic properties, so that e.g. in the actuated stroke end position of the discharge device the component 36 adheres to a component 35 and thus securing this position without a resilient Locking mechanism would be required. From this position the Detection device 44 or units 2, 3 can then by applying a correspondingly large manual force be transferred back to their other end position. The Components 35, 36 can also be in any switching position ensure that a rotating play between magnetic forces the actuators is avoided. Furthermore, the magnetic force the cam 36 with an associated actuator in each switching position burden to the next and therefore also without mutual mechanical drive connection between the Actuators that effect step-by-step switching, see above that a mechanical step switch is not required is.

In the area this drying chamber is the jacket 18 transversely from an opening which penetrates the storage interior with the drying room always connected by line. In the starting position it is Valve 45 closed and opens at the start of the working stroke it because the valve body 46 lifts off the valve body 47. This then creates the storage space with the outside atmosphere Connected via the management gap mentioned. According to 14, the valve body 46 can be formed by the component 34 or on its outer side facing away from room 16 be provided.
