Abstract

The throughflow controlling unit is a valve unit (10) or similar, possibly with two valves (31,32), i.e. a first valve (31) and second valve (32) upstream from the first. In the overhead position of the dispenser (1) and the downwardly directed flow direction, the media throughflow device is cut off by the second valve. The valves have at least one valve seat (33,34) together with first and second valve bodies (35,36) movable relatively to each other and in relation to the housing (4). The second valve body is formed as a driver for the first valve body. To at least one valve seat (33,34) a radial clearance-free guide (51) for the corresponding valve body connects. The guide has peripherally distributed projections (52) and preferably at least one valve body in each position is radial clearance-free centred in relation to the valve seat.

Description

Die Erfindung betrifft einen Spender, insbesondere für fließfähige Medien. Sie können gasförmig, pulverförmig, pastös und/oder insbesondere flüssig sein. Der Spender wird zum Austrag des Mediums mit einer einzigen Hand sowohl getragen als auch betätigt. Seine Ventilanordnung reagiert auf Lageänderungen des Spenders, beispielsweise durch Gravitation, mit unterschiedlichen Ventilstellungen.The invention relates to a donor, in particular for flowable media. They can be gaseous, powder, be pasty and / or in particular liquid. The donor will to discharge the medium with one hand both worn as well as operated. Its valve arrangement reacts changes in the donor's position, for example due to gravity, with different valve positions.

Solche Ventileinheiten können als Auslaßventil, Belüftungsventil, Mischventil o. dgl. der Förder-, Druck- oder Pumpenkammer des Spenders zugeordnet sein. Auch kann die volumenvariable Druckkammer bei ihrer Vergrößerung bzw. Evakuierung aus einem Speicher durch dieses Ventil hindurch mit dem Medium gefüllt werden. Der stromaufwärts liegende Ventilkörper ist nur durch Gravitation in seine Schließstellung zu überführen, während der stromabwärts bzw. näher bei der Druckkammer liegende Ventilkörper durch Überdruck in der Druckkammer in seine Schließstellung überführt wird. Ggf. ist auch eine demgegenüber umgekehrte Anordnung der Ventile bzw. Ventilkörper denkbar. Such valve units can be used as an outlet valve, ventilation valve, Mixing valve or the like of the delivery, pressure or pump chamber assigned to the donor. Also the volume variable Pressure chamber when it is enlarged or evacuated from a store through this valve with the Medium to be filled. The upstream valve body is closed only by gravity transfer while the downstream or closer to the Valve body lying in the pressure chamber due to excess pressure in the Pressure chamber is transferred to its closed position. Possibly. is also a reverse arrangement of the valves or Valve body conceivable.

Bei solchen Spendern kann nachteilig sein, daß das Ventil in einer Endstellung, beispielsweise der Schließstellung, blockiert oder verzögert reagiert, wenn der Ventilkörper durch Unterdruck o. dgl. in seinen Ventilsitz so hineingezogen wird, daß selbst ein höherer Unterdruck auf der anderen Seite nicht sofort ausreicht, ihn aus seinem Sitz herauszuheben. Dies gilt insbesondere für das erste Ventil, welches als Überdruck- oder Rückschlagventil unter dem Überdruck in der Förderkammer schließt und beim Evakuieren dieser Kammer für deren Füllung sofort öffnen sollte. Es kann aber auch für das zweite Ventil gelten.With such dispensers it can be disadvantageous that the valve in an end position, for example the closed position, blocked or responded delayed when the valve body pulled into its valve seat by vacuum or the like is that even a higher negative pressure on the other Side is not immediately sufficient to lift it out of its seat. This applies in particular to the first valve, which as Pressure or check valve under the pressure in the Delivery chamber closes and when evacuating this chamber for whose filling should open immediately. But it can also for that second valve apply.

Ein Spander für Medien gemäß Oberbegriff des Anspruchs 1 ist Beispielsweise aus der FR-A-2- 390 213 bekannt.A spander for media according to the preamble of claim 1 is for example known from FR-A-2- 390 213.

Der Erfindung liegt die Aufgabe zugrunde, einen Spender zu schaffen, bei welchem Nachteile bekannter Ausbildungen bzw. der beschriebenen Art vermieden sind und der insbesondere auch bei miniaturisierter Bauweise und extrem geringen Wandungsdicken seiner Bauteile stets eine sehr sichere Ventilfunktion gewährleistet.The invention has for its object to a donor create the disadvantages of known training or of the type described are avoided and in particular even with miniaturized construction and extremely small Wall thicknesses of its components are always very safe Valve function guaranteed.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Erfindungsgemäß sind Mittel vorgesehen, durch welche die Masse- bzw. Bewegungsenergie des einen Ventilkörpers dazu verwendet wird, den anderen Ventilkörper aus seiner Anschlagstellung, insbesondere seiner Schließstellung, herauszuheben oder herauszustoßen. Dadurch können der erste oder zweite Ventilsitz bzw. Ventilanschlag auch quer oder radial federnd nachgiebig ausgebildet sein und in Schließ- bzw. Anschlagstellung mit Radialspannung am zugehörigen Ventilkörper anliegen, was dessen genauer Zentrierung und sicherer Abdichtung zugute kommt. Die Dicke der den ersten oder zweiten Ventilsitz bildenden Wandung kann unter 1,5 bzw. einem oder 0,8 Millimeter und zweckmäßig zwischen 0,5 und 0,6 Millimeter liegen. So geben sie bei Radialspiel unter dem Anlagedruck des Ventilkörpers leicht nach. Der Sitz kann sich über seinen ganzen Umfang eng an die Form des an ihm anliegenden Bereiches des Ventilkörpers anpassen. Die genannte Wandungsdicke ist zweckmäßig kleiner als die Dicke der Wandung, welche die Förderkammer am Umfang begrenzt. Die Ventilwandung liegt vorteilhaft versenkt bzw. mit Radialabstand innerhalb eines Außenkörpers.This object is solved by the features of claim 1. According to the invention, means are provided by which the Mass or kinetic energy of a valve body is used, the other valve body from its stop position, especially its closed position or push out. This allows the first or second Valve seat or valve stop also springing transversely or radially be flexible and in the closed or stop position with radial tension on the associated valve body concern what its precise centering and secure sealing benefits. The thickness of the first or second Valve seat-forming wall can be under 1.5 or one or 0.8 millimeters and expediently between 0.5 and 0.6 millimeters lie. So they give in radial play under the system pressure of the valve body slightly. The seat can be over his entire circumference closely to the shape of the area adjacent to it adjust the valve body. The wall thickness mentioned is suitably smaller than the thickness of the wall, which the Delivery chamber limited in scope. The valve wall lies advantageously sunk or with a radial distance within a Outer body.

Besonders vorteilhaft ist es, wenn für den ersten oder zweiten Ventilkörper eine Führung vorgesehen ist. Sie ist über den gesamten Bewegungsweg dieses Ventilkörpers im wesentlichen oder vollständig radialspielfrei. So kann der Ventilkörper ohne Querbewegungen sehr schnell von einer Anschlagstellung in die andere überführt werden. Die Führung kann durch mindestens drei oder fünf über den Umfang verteilte Vorsprünge gebildet sein, z.B. durch Längskantenflächen. Diese reichen über den gesamten Bewegungsweg des Ventilkörpers. An ihnen gleitet dieser Ventilkörper bei seinen Bewegungen stets gleitet. Zwischen den Vorsprüngen kann das Medium durch die zugehörige Ventilkammer von deren Einlaß bis zu deren Auslaß strömen. Entlang des zweiten Ventilkörpers ist dabei zweckmäßig der Strömungswiderstand bzw. die Strömungsgeschwindigkeit kleiner als entlang des ersten Ventilkörpers.It is particularly advantageous if for the first or a guide is provided for the second valve body. she is over the entire path of movement of this valve body in essential or completely free of radial play. So he can Valve body without cross movements very quickly by one Stop position to be transferred to the other. The leadership can be distributed across the scope by at least three or five Projections, e.g. through longitudinal edge surfaces. These extend over the entire movement path of the valve body. This valve body slides on them as it moves always glides. Between the protrusions that can Medium through the associated valve chamber from its inlet to flow to the outlet. Along the second valve body the flow resistance or the flow velocity is expedient smaller than along the first valve body.

Der erste und der zweite Ventilkörper weisen zweckmäßig ein gegenüber dem Medium größeres spezifisches Gewicht auf. Er kann Metall, wie Stahl, enthalten. Zur Erhöhung der Masse kann der Ventilkörper nur im Kern aus dem Metall bestehen. Zur Erhöhung der genannten elastischen Stoßwirkung auf den anderen Ventilkörper kann auch seine Stoßfläche bzw. sein Außenumfang aus dem Metall bestehen. Die Ventilsitze bzw. deren Wandungen können wie alle übrigen Wandungen des Spendergehäuses oder der Kolbeneinheit aus Kunststoff bestehen. Die Ventilkörper können eine Bau- bzw. Montageeinheit dadurch bilden, daß sie permanent unmittelbar miteinander über eine Verbindung verbunden sind, welche sich mit mindestens einem der Ventilkörper gegenüber den Ventilsitzen mitbewegt. The first and the second valve body expediently have a greater specific gravity than the medium. He can contain metal such as steel. To increase the mass the valve body can only consist of the metal in the core. To increase the elastic impact on the other valve body can also be its abutting surface or The outer circumference consist of the metal. The valve seats or the walls of which, like all other walls of the dispenser housing or the piston unit are made of plastic. The valve body can be a construction or assembly unit form that they permanently with each other directly over a Connection that is connected to at least one the valve body moves with respect to the valve seats.

In weiterer Ausgestaltung der Erfindung ist mindestens ein Ventilkörper, insbesondere der stromaufwärts oder weiter von der Förderkammer entfernt liegende zweite Ventilkörper durch Leitmittel für die Medienströmung davor geschützt. Dadurch wird er durch die Medienströmung entgegen seiner Gewichtskraft nicht aus seinem zugehörigen Sitz herausgehoben und gegen den anderen Sitz angelegt. Diese Leitmittel können eine Abschirmung umfassen. Sie deckt den Ventilkörper über den größten Teil seiner Grundfläche gegenüber unmittelbare Beaufschlagung der gegen ihn gerichteten Medienströmung ab und führt diese Medienströmung nur in einem Ringkanal um den Ventilkörper herum. Die Medienströmung tritt in die Ventilkammer dieses Ventilkörpers quer ein, nämlich radial unmittelbar gegen die zugehörige Wandung und zwischen deren Vorsprünge gerichtet. Zweckmäßig tritt dabei das Medium nur aus einer einzigen Öffnung aus, welche um die Ventilachse einen Bogenwinkel von weniger als 180° oder 90° einnimmt. Diese Öffnung ist vorteilhaft über ihren gesamten Umfang einteilig begrenzt, beispielsweise von der Leitfläche der genannten Leitmittel. So kann auch die Abschirmung einteilig mit der Wandung dieser Ventilkammer ausgebildet sein.In a further embodiment of the invention, at least one Valve body, especially the upstream or further from through the delivery chamber distant second valve body Guides for the media flow protected from this. Thereby it becomes opposed to its weight by the media flow not lifted out of its associated seat and against the other seat. These guidelines can include a shield. It covers the valve body most of its footprint versus immediate Actuation of the media flow directed against him and only leads this media flow in an annular channel around the Valve body around. The media flow enters the valve chamber this valve body transversely, namely radially directly against the associated wall and between its Projections directed. The medium only expediently occurs from a single opening that extends around the valve axis takes an arc angle of less than 180 ° or 90 °. This opening is advantageous over its entire scope limited in one piece, for example by the guide surface of the mentioned guidelines. The shielding can also be made in one piece be formed with the wall of this valve chamber.

Die Wand 46 weist durchgehend konstante Wandungsdicke auf. Sie liegt wie ihr Tragabschnitt 45 berührungsfrei innerhalb des Mantels 41. Die Wandungen 41, 42, 43, 45 sind einteilig miteinander ausgebildet.The wall 46 is on both end faces or as a whole in Axial section at an obtuse angle and tapering to a point educated. Its outer face forms the conical recessed seat 38. Your interior, opposite to 12 as The end surface protruding from the cone forms a guide surface 49 for the media flow flowing to the unit 10. The wall 46 has a constant wall thickness throughout. she lies like their support section 45 without contact within the shell 41. The walls 41, 42, 43, 45 are in one piece with one another educated.

Beide Enden des Kanales 44, der ebenfalls einteilig mit den genannten Wandungen ausgebildet sein könnte, sind gleich ausgebildet. Sie weisen unebene Endflächen, hier in Radialansicht jeweils eine einzige, stumpfwinklig V-förmige Vertiefung auf. Deren Flanken reichen bis zum Außenumfang und gehen dazwischen konkav ausgerundet ineinander über. Das eine Ende 47 schlägt an der Fläche 49 an. Seine Vertiefung reicht höchstens bis an die Innenseite der Wandung 42. Das andere Ende 48 liegt im Bodenbereich des Speichers 9. An die Innenseite der Wand 42 sowie an die Fläche 49 schließt eine Übertrittsöffnung für das Medium, nämlich ein Austritt 50 an. Er durchsetzt die Wand 45 radial und ist durch die Fläche 49 in Austrittsrichtung stetig erweitert. Der den Austritt 50 umgebende Öffnungsrand kann durchgehend in einer zur Achse 10 parallelen Ebene liegen. Die Wandungen 45, 46 haben dann in Axialansicht die Form eines Ring- bzw. Kreisabschnittes mit einem Bogenwinkel von mehr als 200° bzw. 250°.Both ends of the channel 44, which is also in one piece with the mentioned walls could be formed are the same educated. They have uneven end faces, here in a radial view a single, obtuse-angled V-shaped recess on. Their flanks extend to the outer circumference and go in between concave rounded into each other. One end 47 strikes surface 49. Its deepening is enough at most to the inside of the wall 42. The other End 48 lies in the bottom area of the store 9. On the inside the wall 42 and the surface 49 closes one Transfer opening for the medium, namely an outlet 50. It penetrates the wall 45 radially and is through the surface 49 continuously expanded in the exit direction. The exit 50 surrounding opening edge can be continuous in one to the axis 10 parallel plane. The walls 45, 46 then have in axial view the shape of a ring or circle section with an arc angle of more than 200 ° or 250 °.

Der einzige Austritt 50 ist radial bzw. geringfügig in Richtung 12 geneigt gegen den Innenumfang der Wand 41 gerichtet. So wird die den Ringraum um den Vorsprung 45 füllende Flüssigkeit an der Wand 41 in Richtung 12 umgelenkt und gelangt entlang der Kugel 36 strömend zum Durchlaß 39. Dabei wird die Kugel 36 aus dem Sitz 38 nicht herausgehoben. Die sphärisch gekrümmte Oberfläche der Kugel 36 liegt nur mit einem gegenüber ihrem Durchmesser wesentlich kleineren, insbesondere nur etwa halb so großen Kleinkreis und in der Achse 11 nicht am Sitz 38 an. So kann sie in Ruhelage an diesem Sitz 38 nicht wie in einer becherartigen Aufnahme verklemmen. Die ringförmigen, vom Körper 35 begrenzten Strömungsquerschnitte sind bei geöffneten Ventilen 31, 32 stets wesentlich kleiner als die ringförmig vom Körper 36 begrenzten Strömungsquerschnitte.The only outlet 50 is radial or slightly in Direction 12 inclined towards the inner circumference of the wall 41. Thus, the one that fills the annular space around the projection 45 Liquid deflected on the wall 41 in the direction of 12 and flows along the ball 36 to the passage 39 the ball 36 is not lifted out of the seat 38. The spherically curved surface of the ball 36 lies only with a much smaller diameter in particular only about half the small circle and in the Axis 11 not on seat 38. So it can be in the rest position this seat 38 not as in a cup-like receptacle jam. The ring-shaped, bounded by the body 35 Flow cross sections are when the valves 31, 32 are open always much smaller than that of body 36 limited flow cross sections.

Jede Kugel 35, 36 ist über ihren gesamten, zur Achse 11 parallelen Bewegungsweg gegenüber dem Gehäuse 4 durch gesonderte Führungen genau zentriert. Beispielsweise die Kugel 36 mit der Führung 51. Hierzu sind am Innenumfang der Wand 41 sechs gleichmäßig über den Umfang verteilte Vorsprünge 52, beispielsweise Axialrippen vorgesehen. Sie schließen einteilig an die Wandungen 41, 42, 45, 46 an. An den der Achse 11 gegenüberliegenden Längskantenflächen ist die Kugel 36 geführt. Die Vorsprünge 52 versteifen somit auch die Wandungen 41 bis 43 und 45, 46 gegeneinander. Zwischen den Vorsprüngen sind Kanäle gebildet. Sie verhindern Rotationsströmungen um die Kugel 36 und daher deren Mitnahme durch die Strömung. Die Vorsprünge 52 reichen annähernd bis zum nächstliegenden Sitz 34. Eine entsprechende Führung für die Kugel 35 ist auch vom stromabwärts liegenden Ende des Sitzes 33 bis zum Sitz 37 vorgesehen. Hier haben die Vorsprünge eine kleinere Höhe. Wie Fig. 2 zeigt, kann dem Durchtritt 50 diametral gegenüberliegend eine Rippe 53 vorgesehen sein. Sie versteift die Wandungen 45, 46 unmittelbar gegeneinander, schließt an die Fläche 49 an und verhindert ebenfalls Wirbel bzw. Drehströmungen.Each ball 35, 36 is over its entire axis 11 parallel movement path relative to the housing 4 by separate Guides exactly centered. For example, the ball 36 with the guide 51. For this purpose, on the inner circumference of the wall 41 six projections 52 evenly distributed over the circumference, provided for example axial ribs. They close in one piece to the walls 41, 42, 45, 46. On the axis 11 opposite longitudinal edge surfaces is the ball 36 guided. The projections 52 thus also stiffen the walls 41 to 43 and 45, 46 against each other. Between the ledges channels are formed. They prevent rotation currents around the ball 36 and therefore its entrainment by the Flow. The projections 52 extend approximately to the nearest one Seat 34. A corresponding guide for the ball 35 is also from the downstream end of the seat 33 to provided for seat 37. Here the ledges have one smaller height. 2 shows, the passage 50 can be diametrical a rib 53 may be provided opposite. she stiffen the walls 45, 46 directly against each other, connects to surface 49 and also prevents eddies or three currents.

Der stromaufwärts liegende Endabschnitt 54 des Ansatzes 28 ist erst ab dem Widerlager 30 entgegen Richtung 12 am Außenund Innenumfang verengt. So ist er von seinem freien Ende und in Richtung 12 über die Sitze 30, 33, 37 hinaus gegenüber dem Innenumfang der Wandung 41 und der Führung 51 berührungsfrei. Entgegen Richtung 12 wird die Mantelwandung 54 bis einschließlich des Sitzes 33 dünner, dann geringfügig dicker und im Bereich des Sitzes 34 wieder dünner. So läßt sie sich elastisch rückfedernd unter dem Anlagedruck der Kugel 35 bzw. 36 verformen und dicht an die Kugel anlegen, ohne durch Anschlag am Gehäuseteil 7 daran gehindert zu sein. Der mittlere Abstand zwischen den voneinander wegweisenden Sitzen 33, 34 ist kleiner als die Hälfte oder ein Drittel des Kugeldurchmessers. Der ist seinerseits kleiner als 5 mm und größer als 2 mm. Der Abstand zwischen den einander zugekehrten Sitzen 37, 38 ist höchstens vier- oder dreimal so groß wie dieser Kugeldurchmesser. So ergeben sich sehr kurze Steuerwege der Ventile 31, 32. Der Steuerweg der Kugel 35 ist aber wesentlich kleiner als der der Kugel 36. Der größte Zentrumsabstand zwischen den Kugeln 35, 36 ist kleiner als das Dreifache oder Doppelte ihres Durchmessers. Beide Kugeln sind gleich ausgebildet und gleich groß. Sie können ohne weiteres gegeneinander ausgetauscht werden. Die Feder 55 bildet mit ihrer Endwindung den Sitz 37. Sie stützt sich mit ihrem anderen, stromabwärts liegenden Ende am Körper 23 wie an der Fläche 30 stets axial vorgespannt ab.The upstream end portion 54 of the boss 28 is only from the abutment 30 against direction 12 on the outside and Narrow inside circumference. So it is from its free end and towards 12 across seats 30, 33, 37 opposite the inner circumference of the wall 41 and the guide 51 without contact. Contrary to direction 12, the jacket wall 54 to including the seat 33 thinner, then slightly thicker and thinner again in the area of the seat 34. So it can be resiliently resilient under the contact pressure of the ball 35 or 36 deform and lay close to the ball without going through Stop on the housing part 7 to be prevented. The average distance between the pioneering seats 33, 34 is less than half or a third of that Ball diameter. For its part, it is smaller than 5 mm and larger than 2 mm. The distance between the facing each other Sitting 37, 38 is at most four or three times as big as this ball diameter. So there are very short ones Control paths of the valves 31, 32. The control path of the ball 35 is but much smaller than that of the ball 36. The largest Center distance between the balls 35, 36 is less than three times or twice their diameter. Both balls are equally trained and of the same size. You can without further exchanged against each other. The spring 55 forms the seat 37 with its end turn. It supports itself with its other, downstream end on the body 23 like always axially biased on surface 30.

In der Normallage ist die Strömung 12 nach oben gerichtet, da der Speicher 9 unterhalb des Betätigungskopfes liegt. Bei manueller Betätigung entgegen Richtung 12 werden zunächst die Ventile 26, 31 durch die Schubbewegung bzw. den Überdruck in der Kammer 20 geschlossen. Danach wird das Medium in der Kammer 20 komprimiert und nach Öffnung des Ventiles 22 über den Auslaßkanal 21 in den Betätigungskopf und durch dessen Düse ins Freie ausgetragen. Während des gesamten Vorhubes kann über das Ventil 24 und die Öffnung 25 atmosphärische Luft in den Speicher 9 angesaugt werden. Mit Beginn des Rückhubes schließt das Ventil 22. So wird im weiteren Verlauf die Kammer 20 evakuiert, dadurch das Ventil 31 geöffnet und das Medium nacheinander durch das Rohr 44, die Öffnung 50, die Ventilkammer 56, den Durchlaß 39 und den Sitz 37 in die Kammer 20 angesaugt. Die die Kugel 36 stets aufnehmende Kammer hat eine größere Weite als die die Kugel 35 stets aufnehmende Kammer. Dadurch werden die unterschiedlichen Durchlaßquerschnitte erreicht. Während des gesamten Vor- und Rückhubes verbleibt die Kugel 36 auf dem Sitz 38. Am Ende des Rückhubes öffnet zuerst das Ventil 26. Unmittelbar darauffolgend schließt das Ventil 24. Ein weiterer Pumpzyklus dieser Art kann nun beginnen.In the normal position, the flow 12 is directed upwards because the memory 9 is below the actuating head. at manual actuation against direction 12 are the first Valves 26, 31 by the thrust movement or the excess pressure in the chamber 20 closed. Then the medium in the Chamber 20 compresses and after opening the valve 22 over the outlet channel 21 in the actuating head and through it Nozzle discharged outdoors. During the entire preliminary stroke can be atmospheric via the valve 24 and the opening 25 Air is sucked into the memory 9. With the beginning of the The return stroke closes the valve 22 the chamber 20 evacuated, thereby opening the valve 31 and the medium successively through the tube 44, the opening 50, the valve chamber 56, the passage 39 and the seat 37 in the Chamber 20 sucked. The ball 36 always receiving Chamber has a larger width than the ball 35 always receiving chamber. This makes the different Passage cross sections reached. Throughout the pre and Return stroke, the ball 36 remains on the seat 38. At the end of Return stroke first opens valve 26. Immediately afterwards closes valve 24. Another pump cycle of this kind can now begin.

Bei Überkopflage gemäß Fig. 2 liegt der Betätigungskopf unterhalb des Speichers. Die Kugel 36 fällt daher unter ihrer Gewichtskraft aus dem Sitz 38 in den Sitz 34. Die Kugel 35 fällt unter ihrer Gewichtskraft aus dem Sitz 33 in den Sitz 37. So ist das Ventil 32 geschlossen und das Ventil 31 geöffnet. Beim Vorhub bis zur Hubendstellung gemäß Fig. 2, in welcher der Körper 23 in die Kammer 29 ragt, schließt das Ventil 31 unter dem Druck in der Kammer 20. Dabei hebt die Kugel 35 die Kugel 36 aus ihrem Sitz 34 heraus. Erst dann erreicht sie den Sitz 33. Das Medium wird wieder in der beschriebenen Weise ausgetragen. Dabei ruht während des gesamten Vorhubes die Kugel 36 unter ihrer Gewichtskraft auf der Kugel 35 und berührt diese punktförmig. Beginnt der Rückhub aus der Stellung gemäß Fig. 2, so öffnet zwar zunächst das Ventil 31, indem die Kugel 35 vom Sitz 33 abhebt. Simultan und gleichlaufend rückt jedoch die Kugel 36 unter ihrem Gewicht bis zum Eingriff in den Sitz 34 nach. Erst danach löst sich die Kugel 35 von der Kugel 36 und legt dann einen nochmals höchstens gleichlangen Weg bis zur Anlage am Sitz 37 zurück. Bei nach unten gerichteter Strömungsrichtung 12 ist daher die Einheit 10 durch das Ventil 32 geschlossen. So kann über das Rohr 44 kein Medium in die Kammer 56 angesaugt werden. Vielmehr wird die Kammer 20 trocken evakuiert. 2 is the actuating head below the store. The ball 36 therefore falls below their weight from the seat 38 in the seat 34. Die Ball 35 falls out of seat 33 under its weight the seat 37. So the valve 32 is closed and the valve 31 open. In the forward stroke up to the stroke end position according to FIG. 2, in which the body 23 protrudes into the chamber 29, that closes Valve 31 under the pressure in chamber 20. This raises the Ball 35, ball 36 out of its seat 34. Only it reaches the seat 33. The medium is again in the carried out described manner. It rests during the entire advance stroke the ball 36 under its weight the ball 35 and touches it punctiform. The begins Return stroke from the position shown in FIG. 2, so opens first the valve 31 by lifting the ball 35 from the seat 33. Simultaneously and simultaneously, however, the ball 36 moves under their weight until they engage the seat 34. First then the ball 35 detaches from the ball 36 and then sets one more way of the same length to the facility on Seat 37 back. With the flow direction pointing downwards 12 unit 10 is therefore closed by valve 32. So no medium can be sucked into the chamber 56 via the pipe 44 become. Rather, the chamber 20 is evacuated dry.

Erst wenn das Ventil 26 öffnet wird allein über die Öffnung 25 mit wesentlich höherer Strömungsgeschwindigkeit als über die Ventileinheit 10 das Medium aus dem Speicherraum unmittelbar durch den Mantel 15 in die Kammer 20 angesaugt. Der nächste Vor- bzw. Austraghub kann daher beginnen.Only when the valve 26 opens is the opening alone 25 with a significantly higher flow rate than above the valve unit 10 directly receives the medium from the storage space sucked through the jacket 15 into the chamber 20. The The next advance or discharge stroke can therefore begin.

Es ist auch denkbar, die Sitze 33, 34 gegeneinander gerichtet anzuordnen. Dazwischen wäre nur eine Ventilkugel vorzusehen. Sie kann abwechselnd immer nur einen der Sitze schließen. Ein weiterer, ggf. kugelförmiger Stoßkörper könnte dann stromauf- bzw. stromabwärts der Sitze vorgesehen sein. Er stößt die Ventilkugel aus dem jeweils benachbarten Sitz. Der jeweilige Stoßkörper könnte in der Kammer 29 bzw. 56 bewegbar sein. Beim Umdrehen des Spenders 1 aus der Lage gemäß Fig. 2 in die Lage gemäß Fig. 1 fallen die Kugeln 35, 36 unter ihrem Gewicht wieder zurück in den Sitz 33 bzw. 38. Durch die Führungen 51 arbeiten die Ventile 31, 32 auch in jeder Schräglage des Spenders 1 bzw. der Achse 11.It is also conceivable for the seats 33, 34 to face each other to arrange. Only one valve ball should be provided in between. It can alternately close only one of the seats. On further, possibly spherical impact body could then upstream or downstream of the seats. He pushes the Valve ball from the adjacent seat. The respective The impact body could be movable in the chamber 29 or 56. When turning the dispenser 1 from the position shown in FIG. 2 in the 1, the balls 35, 36 fall below their Weight back into the seat 33 or 38. By the Guides 51, the valves 31, 32 also work in each Oblique position of dispenser 1 or axis 11.

Das stromabwärts liegende Ende des Gehäuseteils 7 weist einen gegenüber dem Mantel 41 verdickten Ringflansch auf, der nur über den Außenumfang vorsteht und am Gehäuseteil 5 an einer äußeren Schulterfläche anliegt. Diese ist durch denselben, ringförmigen und quer zur Achse 11 liegenden Übergangs- bzw. Wandungsabschnitt wie die Fläche 27 gebildet. Dieser Wandungsabschnitt verbindet die Mäntel 15, 28 miteinander und bildet an seiner Außenseite über den Umfang mit gegenseitigem Abstand verteilte Vorsprünge bzw. Rippen 57. Zwischen ihnen liegen Nuten. So ist eine sehr sichere Anlage der Endfläche des Mantels 41 an den Kantenflächen der Rippen 57 gewährleistet. Außerdem kann mit einem Werkzeug zwischen die Rippen 57 eingegriffen und dadurch der Gehäuseteil 7 axial vom Gehäuseteil 5 entgegen Richtung 12 wegge drückt werden. The downstream end of the housing part 7 has one compared to the jacket 41 thickened ring flange, which only protrudes over the outer circumference and on the housing part 5 at one outer shoulder surface. This is through the same, annular and transitional or transverse to the axis 11 Wall section formed as the surface 27. This wall section connects the coats 15, 28 to each other and forms on the outside about the perimeter with mutual Spacings distributed between projections or ribs 57. Between them there are grooves. This is a very safe installation of the end face of the jacket 41 guaranteed on the edge surfaces of the ribs 57. You can also use a tool between the ribs 57 intervened and thereby the housing part 7 axially from Housing part 5 are pressed against direction 12 wegge.

Zur Montage kann die Kugel 35 zuerst entgegen Richtung 12 und ohne Überwindung einer Rast- bzw. Schnappstelle in den Ansatz 28 eingesetzt werden. Danach werden die Feder 55 und die Kolbeneinheit 8 sowie danach der Deckel 6 in derselben Richtung in ihre betriebsgerechte Lage eingesetzt. Vor oder nach diesen Montageschritten wird die Kugel 36 entgegen Richtung 12 in den Gehäuseteil 7 eingesetzt. Danach wird der Teil 7 in Richtung 12 über den Ansatz 28 aufgeschoben. Nach dem Einsetzen des so montierten Spenders 1 in den Speicher 9 liegen alle Ventile 10, 22, 24, 26 wie auch die Kammer 20 und die Öffnung 25 stromaufwärts von der Ebene 13. Vom Speicherhals und dem Mantel 15 ist dann ein Ringkanal für die Belüftung des Speicherraumes begrenzt. Die Teile 5 bis 7, 19, 35, 36 sind bis auf die Hülse 54 formsteif.For assembly, the ball 35 can first counter to the direction 12 and without overcoming a rest or snap point in the approach 28 are used. Then the spring 55 and the Piston unit 8 and then the cover 6 in the same Direction used in their operationally appropriate position. Before or after these assembly steps, the ball 36 is countered Direction 12 inserted into the housing part 7. Then the Part 7 pushed in the direction of 12 over the approach 28. To inserting the dispenser 1 thus assembled into the memory 9 are all valves 10, 22, 24, 26 as well as the chamber 20 and opening 25 upstream from level 13. From the storage neck and the jacket 15 is then an annular channel for ventilation of the storage space limited. Parts 5 to 7, 19, 35, 36 are dimensionally stable except for the sleeve 54.

Der hier durch den Deckel gebildete Endabschnitt des Gehäuses 4 kann auch einteilig mit dem Gehäuseteil 5 ausgebildet sein, das dann den Flansch 14 bildet. Alle angegebenen Eigenschaften und Wirkungen können genau oder nur im wesentlichen bzw. etwa wie beschrieben vorgesehen sein und je nach Anforderungen an den Spender auch stark davon abweichen.The end section of the housing formed here by the cover 4 can also be formed in one piece with the housing part 5, which then forms the flange 14. All specified properties and effects can be precise or only essential or be provided as described and depending on requirements to the donor also differ greatly.
