Opfindelsen angår en indretning til afgivelse af viskose koncentrater af foranderlig viskositet i nøjagtigt doserbare mængder af foranderligt indstilleligt volumen, navnlig til drikkevareautomater, dels med en 5 ringformet, såsom elektromagnetisk arbejdende, drivindretning med aksialt bevægeligt drivelement, og dels med et udleveringsafsnit omfattende en pumpeenhed med et pumpekammer, med et indløb og et udløb, hvor indløbet kan tilsluttes en beholder for koncentratet, og hvor 10 der i pumpekammerets afgrænsning indgår en elastisk bælg, der kan sammentrykkes af drivelementet, hvilken pumpeenhed er indrettet med organer ved pumpekammerets indløb og udløb til sikring af en ensrettet strømning gennem pumpekammeret, hvilke organer omfatter mindst 15 én kontraventil ved pumpekammerets indløb, og hvilket pumpekammer udvides aksialt under udnyttelse af fjedervirkning fra bælgen.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device for delivering viscous concentrates of variable viscosity in accurately dispensable amounts of changeable adjustable volume, in particular to beverage dispensers, partly with an annular such as electromagnetic working, drive device with axially movable drive member, and partly with a dispensing section. a pumping chamber, having an inlet and outlet, where the inlet can be connected to a container for the concentrate, and wherein the delimitation of the pumping chamber includes an elastic bellows which can be compressed by the drive element, which pump unit is arranged with means at the pump inlet and outlet for protection. of a unidirectional flow through the pumping chamber, which means comprises at least one check valve at the inlet of the pumping chamber, and which pumping chamber is axially widened utilizing spring action from the bellows.
En indretning af denne art er kendt fra GB-of-fentliggørelsesskrift nr. 2.037.255. Det drejer sig dér 20 om en indretning, der først og fremmest er bestemt for indbygning i drikkevareautomater, og som derfor er underkastet betydelige indskrænkninger med hensyn til såvel doseringsvolumen som indretningens indbygningsplads.A device of this kind is known from GB Patent Specification No. 2,037,255. 20 is a device which is primarily intended for incorporation in beverage vending machines, and which is therefore subject to significant restrictions on both the dosage volume and the device's installation space.
Ved den kendte indretning med elastisk deformer-25 bart udleveringsafsnit er doseringsnøjagtigheden forholdsvis lille, idet det elastisk deformerbare afsnit deformerer sig ukontrollerbart under pumpetrykket. Disse deformationer bliver desto større jo større pumpekammerets volumen er. Ved små formændringer er materialets 30 formelastiske tilbagestillingskraft for det meste for lille til at sikre en nøjagtig tilbagestilling af pumpekammerets bevægelige elementer til udgangsstillingen.In the known device with elastically deformable dispensing section, the dosage accuracy is relatively small, the elastically deformable section deforming uncontrollably under the pump pressure. These deformations become larger the larger the volume of the pump chamber. In the case of small mold changes, the mold elastic reset force of the material 30 is usually too small to ensure an accurate reset of the pump chamber moving elements to the initial position.
Dette indvirker uheldigt på doseringsprocessens nøjagtighed og reproducerbarhed. Med den nævnte kendte ind-35 retning kan der derfor kun ske en doseret afgivelse af forholdsvis store volumener med en kun forholdsvis lille gentagelsesfrekvens. Ved et forholdsvis stort volumen 2 151118 skal der her forstås et volumen på f.eks. 0,4 cm .This adversely affects the accuracy and reproducibility of the dosing process. Therefore, with the known device, a dosed delivery of relatively large volumes with a relatively low repetition frequency can only occur. By a relatively large volume 2, here is meant a volume of e.g. 0.4 cm.
Opfindelsen har til opgave at udforme den indledningsvis omtalte indretning på en sådan måde, at der med stor nøjagtighed kan afgives en forudbestemt lille 5 væskemængde for hvert pumpeslag, selv om pumpeslagene udføres med høj cyklusfrekvens.It is the object of the invention to design the device mentioned in the introduction in such a way that a predetermined small amount of liquid can be dispensed for each pump stroke with great accuracy, although the pump stroke is performed at a high cycle frequency.
Til opnåelse heraf er indretningen ifølge opfindelsen ejendommelig ved, at pumpekammeret er afgrænset af to stive hulcy-10 lindriske dele, der kan bevæges i aksial retning i forhold til hinanden, og som via bælgen er forbundet med hinanden og i det mindste ved enden af pumpeslaget understøtter bælgen formbestandigt udvendig fra, at bælgen er forsynet med en fold, der med sin 15 kam strækker sig radialt indad, at pumpekammeret er anbragt i forlængelse af og i anlæg med drivelementet, der strækker sig gennem den centrale ringåbning i drivindretningen, at bælgens aksiale udvidelse frembringes ved fje-20 dervirkning fra bælgen selv og en eventuel fjederindretning , og at slaglængden og fjederkraften, der bestemmer bælgens udvidelse, er indstillelig på en sådan måde, at pumpekammerets volumen kan sammentrykkes med en cyklus-25 frekvens på mellem 10 og 1Q0 Hz.To achieve this, the device according to the invention is characterized in that the pump chamber is bounded by two rigid hollow cylindrical parts which can be moved in axial direction relative to each other and which are connected to each other via the bellows and at least at the end of the pump stroke. supports the bellows mold-resistant exterior from the bellows being provided with a fold extending radially inwardly with its cam, the pump chamber being extended and in contact with the drive element extending through the central ring opening in the drive device, the axial bellows expansion is produced by spring action from the bellows itself and any spring device, and the stroke and spring force determining the expansion of the bellows are adjustable in such a way that the volume of the pump chamber can be compressed with a cycle frequency of between 10 and 1Q0 Hz .
Med denne udformning er der skabt en konstruktion, der - som det også vil fremgå af det følgende - opfylder de stillede krav og derved har væsentlige tekniske fordele i sammenligning med den kendte konstruktion til 30 lignende formål.With this design, a structure has been created which - as will also be apparent from the following - meets the requirements set and thereby has significant technical advantages in comparison with the known construction for similar purposes.
Indretningen ifølge opfindelsen muliggør, at delene, der begrænser pumpekammerets indstillelige volumen, sammen med drivelementet kan anbringes inden for det snævre område, som strækker sig gennem drivindret-35 ningen. Ved en sådan indretning kan man følgelig udnytte 3 151118 den sædvanlige centrale åbning til anbringelse af delene, der begrænser pumpekammeret, og drivelementet. Der sker herved en betydelig reduktion af indretningens indbygningsvolumen i aksial retning, uden at de radiale di-5 mensioner forøges i forhold til, hvad der gør sig gældende ved den kendte indretning.The device according to the invention allows the parts limiting the adjustable volume of the pump chamber together with the drive element to be placed within the narrow area extending through the drive device. Accordingly, in such a device, the usual central aperture can be utilized for placing the parts limiting the pump chamber and the drive element. Thereby, there is a considerable reduction of the device's volume of installation in the axial direction without increasing the radial dimensions in relation to what is known in the known device.
Udformningen ifølge opfindelsen muliggør, at det pr. pumpecyklus fortrængelige volumen kan gøres meget lille - ikke kun i radial retning, men også i aksial 10 retning. Alligevel opnås der en meget høj nøjagtighed med hensyn til doseringsprocessens volumendosering og reproducerbarhed. Dette muliggøres først og fremmest af den omstændighed, at det andet område, der begrænser pumpekammeret, består dels af en bælg med en fold, der 15 med sin kam strækker sig radialt indad, og dels af to stive hulcylindriske dele, der er forbundet med hinanden via denne ene fold. Herved understøttes folden - i det mindste ved enden af pumpeslaget - mod formændringer udadtil, idet den på dette tidspunkt er indesluttet 20 fuldstændigt af de to stive hulcylindriske dele. Herved indvirkes der ikke uheldigt på bevægeligheden og fleksibiliteten af bælgen, f.eks. ved friktion. Følgen er en afgørende forbedring af volumennøjagtigheden af den pr. cyklus afgivne mængde. Den samtidigt sikrede lette be-25 vægelighed fører til en høj reproducerbarhed af udleveringsprocessen såvel som en meget høj udleveringsfrekvens på mindst 10 Hz. Slaglængden og forspændingskraften, der med en forudbestemt kraft holder de hulcylindriske dele tvunget fra hinanden i retning af deres 30 hvilestilling, kan derved vælges således, at indretningens bevægelige enhed fuldt og sikkert kan gennemløbe den forudbestemte slaglængde med en frekvens på indtil 1QQ Hz.The design according to the invention enables pump cycle displaceable volume can be made very small - not only in the radial direction, but also in the axial direction. Yet, a very high accuracy is achieved in terms of volume dosing and reproducibility of the dosing process. This is primarily made possible by the fact that the second area limiting the pump chamber consists partly of a bellows having a fold extending radially inwardly with its cam, and partly of two rigid hollow cylindrical portions connected to each other. via this one fold. Hereby, the fold - at least at the end of the pump stroke - is supported against outward shape changes, at this point being completely enclosed by the two rigid hollow cylindrical parts. This does not adversely affect the movement and flexibility of the bellows, e.g. by friction. The result is a significant improvement in the volume accuracy of the per. quantity delivered cycle. The simultaneous ease of movement leads to a high reproducibility of the dispensing process as well as a very high dispensing frequency of at least 10 Hz. The stroke length and the bias force which with a predetermined force keep the hollow cylindrical parts forced apart in the direction of their resting position can thus be chosen so that the movable unit of the device can fully and safely pass through the predetermined stroke length at a frequency of up to 1QQ Hz.
Med indretningen ifølge opfindelsen opnår man så-35 ledes to betydelige fordele, nemlig en væsentlig reduk- 4 151118 tion af den for indretningen nødvendige indbygningsplads såvel som en væsentligt højere doseringsnøjagtig-hed. Større mængder, der skal afgives, lader sig derved let og nøjagtigt sammensætte ud fra et tilsvarende an-5 tal af sådanne pumpecykler. Den høje pumpefrekvens sikrer, at substansen, der skal doseres, afgår som en praktisk taget ensartet strøm fra indretningens udleveringsåbning. Det er ved indretningen ifølge opfindelsen særlig fordelagtigt, at den til enhver tid forhåndenværende 10 netfrekvens kan anvendes umiddelbart som styrestørrelse for pumpekrekvensen. Dette fører til en enorm forenkling af anordningen. Denne er særlig robust, såfremt udleveringsafsnittets første område, dvs. pumpeenheden, der strækker sig gennem den centrale åbning i drivindret-15 ningen, er udformet som et stift føringsrør for de hulcylindriske dele.Thus, with the device according to the invention, two significant advantages are achieved, namely a substantial reduction of the installation space required for the device as well as a substantially higher dosing accuracy. Larger amounts to be dispensed are thereby easily and accurately composed from a corresponding number of such pump cycles. The high pump frequency ensures that the substance to be dispensed exits as a practically uniform flow from the dispensing opening of the device. It is particularly advantageous in the device according to the invention that the available grid frequency can be used at any time immediately as control size for the pump frequency. This leads to a huge simplification of the device. This is particularly robust if the first area of the delivery section, ie. the pump unit extending through the central opening of the drive device is configured as a rigid guide tube for the hollow cylindrical portions.
En anden fordelagtig udførelsesform for indretningen ifølge opfindelsen er ejendommelig ved, at de stive hulcylindriske dele er udformet som slagbegræns-20 ningsanslag, der endesidigt kommer i gensidigt anlæg.Another advantageous embodiment of the device according to the invention is characterized in that the rigid hollow cylindrical parts are designed as impact limiting stops which end up in reciprocal abutments.
Ved en indstilling af pumpekammerets volumen sikres der herved alligevel, at bælgen - i det mindste ved enden af pumpeslaget - er indesluttet fuldstændigt af de hulcylindriske dele.By adjusting the volume of the pump chamber, it is thus nevertheless ensured that the bellows - at least at the end of the pump stroke - is completely enclosed by the hollow cylindrical parts.
25 Den ene af de to hulcylindriske dele kan være indsat fast i føringsrøret. Den anden hulcylindriske del er derimod fordelagtigt forbundet fast med det tilsvarende hulcylindrisk udformede drivelement til en bevægelsesenhed. Denne kan med fordel også omfatte kontra-30 ventilen, der befinder sig ved indløbssiden, og som følgelig deltager i bevægelserne under pumpeprocessen. Indretningen ifølge opfindelsen egner sig på grund af sit lille pladsbehov - også uden videre for senere udrustning af kendte automater, for så vidt deres do-35 seringsindretninger har en elektromagnetisk ringspole.One of the two hollow cylindrical parts may be inserted firmly into the guide tube. The second hollow cylindrical portion, on the other hand, is advantageously connected firmly to the corresponding hollow cylindrical shaped drive member for a moving unit. This may advantageously also include the check valve located at the inlet side, which consequently participates in the movements during the pumping process. The device according to the invention is suitable because of its small space requirement - even without later for later equipment of known machines, insofar as their dosing devices have an electromagnetic ring coil.

Denne udrustning respektive omstilling medfører, at der kan gås over fra den sædvanlige tidsstyrede dosering til en mængde- eller volumenstyret dosering.This equipment or conversion means that the usual time-controlled dosing can be switched to a volume- or volume-controlled dosing.
Opfindelsen forklares nærmere i det følgende 5 under henvisning til tegningen, hvor fig. 1 viser i vertikalsnit en til oplagring, transport og udlevering tjenende beholder, hvortil der hører en indretning ifølge opfindelsen med et udleveringsafsnit, 10 fig. 2 udleveringsafsnittet i større skala, med de tilhørende enkeltdele vist i en fra hinanden udtrukket stilling, og fig. 3 i vertikalsnit en anden udførelse af udleveringsafsnittet .The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 is a vertical sectional view of a container for storage, transport and delivery, to which a device according to the invention has a dispensing section; FIG. 2 shows the dispensing section on a larger scale, with the associated individual parts shown in a pulled apart position, and FIG. 3 in vertical section another embodiment of the dispensing section.
15 Opfindelsen forklares i det følgende ved et ud førelseseksempel i form af en éngangsbeholder, der tjener til såvel oplagring og transport som doseret udlevering, og hvortil der hører en indretning ifølge opfindelsen med et udleveringsafsnit 4, fig. 1, der for-20 trinsvis er forbundet vedvarende med beholderen og derfor bortkastes sammen med denne. Der er altså tale om en beholder fremstillet som masseartikelvThe invention is explained in the following by an exemplary embodiment in the form of a disposable container which serves both storage and transport as well as dosed dispensing, and to which a device according to the invention has a dispensing section 4, fig. 1, which is preferably permanently connected to the container and therefore discarded therewith. This is a container made as a bulk article
Beholderen kan bestå af et ydre hylster og en indre fleksibel pose, der optager væsken, og som under ud-25 leveringen foldes tilsvarende sammen. I dette tilfælde kræver udleveringen ingen luftning af beholderen. Der kan imidlertid også være tale om en i hovedsagen stiv beholder, hvortil der med henblik på udlevering hører en betjenelig luftningsindretning.The container may consist of an outer casing and an inner flexible pouch which receives the liquid and which during delivery is folded accordingly. In this case, the dispensing does not require aeration of the container. However, it may also be a substantially rigid container to which a reliable aeration device belongs.
30 Beholderen er fortrinsvis bestemt til såvel op tagelse, oplagring og transport som udlevering af organiske koncentrater.Preferably, the container is intended for both uptake, storage and transport as well as delivery of organic concentrates.
I eksemplet i fig. 1 er beholderen udformet med et ydre hylster 1 og en fleksibel sammenfaldende påfyld-35 ningsbeholder 2. Denne beholder har et mundstykke 3, hvortil udleveringsafsnittet 4 fortrinsvis er fastgjort vedvarende. I fig. 1 er beholderen vist i den 6 151118 stilling, i hvilken den befinder sig under den doserede udlevering af væsken. I denne stilling strækker udleveringsafsnittet 4 sig gennem en central åbning i en drivindretning 5 i form af en elektromagnetisk ring-5 spole, der f.eks. kan være indbygget fast i en drikkevareautomat eller -dispenser. Den elektromagnetiske ring-spole 5 er sluttet til et tilsvarende styreaggregat, som f.eks. muliggør drivning af ringspolen 5 med netfrekvensen, hvor antallet af frekvenssvingninger, som 10 ringspolen 5 skal følge, kan indstilles på styreaggregatet.In the example of FIG. 1, the container is formed with an outer casing 1 and a flexible collapsible filling container 2. This container has a nozzle 3, to which the dispensing section 4 is preferably permanently attached. In FIG. 1, the container is shown in the 6 position in which it is located during the dosed delivery of the liquid. In this position, the dispensing section 4 extends through a central opening in a drive device 5 in the form of an electromagnetic ring-5 coil, e.g. may be built into a beverage dispenser or dispenser. The electromagnetic ring coil 5 is connected to a corresponding control unit, such as e.g. enables driving of the ring coil 5 at the grid frequency, where the number of frequency oscillations that the ring coil 5 must follow can be set on the control unit.
Udleveringsafsnittet 4 har et stift føringsrør 6, der består af formstof, og som med sin øvre ende er forbundet vedvarende med beholderens mundstykke 3.The dispensing section 4 has a rigid guide tube 6, which is made of plastic material, which with its upper end is connected permanently to the nozzle 3 of the container.
15 Føringsrøret 6 har over sin større længde et tværsnit, der udvider sig via en ansats 35, fig. 2, og som er frit ved den nedre ende. Til føringsrøret 6 hører der et stift endedæksel 26, der har en central udløbsstuds 27. I det viste eksempel er føringsrørets to dele 6 20 og 26 forbundet med hinanden via et navformet ventillegeme 20, der på sin omkreds har en ringflange 22, som føringsrøret respektive lukkedækslet 26 kan trykkes fast op til fra begge ender. På denne måde bliver det navformede ventillegeme 20 samtidig forbundet 25 stift .med føringsrøret 6 og lukkedækslet 26.15 The guide tube 6 has over its greater length a cross-section which extends via an abutment 35, fig. 2, which is free at the lower end. The guide tube 6 includes a rigid end cover 26 having a central outlet nozzle 27. In the example shown, the two parts 6 20 and 26 of the guide tube are connected to each other via a hub-shaped valve body 20, which at its perimeter has an annular flange 22 the closure cover 26 can be pressed firmly up from both ends. In this way, the hub-shaped valve body 20 is simultaneously connected rigidly to the guide tube 6 and the closure cover 26.
I det yderligere afsnit af føringsrøret 6 er der med frit spillerum optaget et andet lignende navformet ventillegeme 8, så dette kan bevæge sig frit i aksial retning i føringsrøret 6. På en foroven mod 30 beholderen 1 vendende, studsformet ende af ventillegemet 8, der består af formstof, er der fast anbragt et drivelement 7 bestående af en magnetiserbar bøsningsdel i form af et ringanker, der med sin nedre ringformede endeside ligger an mod en ansats 9 på 35 ventillegemet 8. Ventillegemet 8 og ringankeret 7 danner således en stiv enhed, der som antydet med en 7 151118 dobbeltpil 31 kan bevæges aksialt opad og nedad i føringsrøret 6.In the further section of the guide tube 6, another similar clearance-shaped valve body 8 is accommodated so that this can move freely in the axial direction in the guide tube 6. On a top-facing, stud-shaped end of the valve body 8, which consists of of resin, a drive member 7 is constituted permanently of a magnetizable bushing member in the form of an annular anchor which, with its lower annular end face, abuts an abutment 9 of the valve body 8. The valve body 8 and annular 7 thus form a rigid unit which as indicated by a double arrow 31 can be moved axially upwards and downwards in the guide tube 6.
De mod hinanden vendende ender af ventillegemerne 8 og 20 har optage- og fastgørelsesafsnit 10, 11 5 respektive 19, 21 for bøsningsformede ender 16 re spektive 18 af et hulcylindrisk legeme i form af en bælg 15. I det viste eksempel består bælgen 15 af et elastisk materiale og er derved samtidig udformet som et elastisk fjederelement. Bælgen 15 har dels for-10 tykkede endeafsnit 16 og 18 til fastgørelse på de to ventillegemer 8 og 20, og dels et fortyndet afsnit, som befinder sig i en radialt indadragende fold 17. Forbindelsen mellem de navformede ventillegemer 8 og 20 via bælgen 15 bevirker, at der mellem disse 15 dele indesluttes et forudbestemt doseringsvolumen. Udgangsstørrelsen af dette volumen bestemmes af bælgen 15's tilbagestillingskraft i forbindelse med føringsrøret 6's indvendige ansats 35, mod hvilken den øvre ringformede endeflade af ringankeret 7 ligger an i 20 hvilestillingen.The opposite ends of the valve bodies 8 and 20 have receiving and fastening sections 10, 11 and 19, 21 respectively for bush-shaped ends 16 respectively 18 of a hollow cylindrical body in the form of a bellows 15. In the example shown, the bellows 15 consists of a elastic material and is thereby simultaneously formed as an elastic spring element. The bellows 15 has partly thickened end portions 16 and 18 for attachment to the two valve bodies 8 and 20 and partly a diluted portion which is in a radially inwardly folding fold 17. The connection between the hub-shaped valve bodies 8 and 20 via the bellows 15 causes that between these 15 parts a predetermined dosage volume is enclosed. The output size of this volume is determined by the reset force of the bellows 15 in connection with the inner shoulder 35 of the guide tube 6 against which the upper annular end face of the ring anchor 7 abuts in the resting position.
I det viste eksempel har hvert ventillegeme 8 respektive 20 en central boring 12 respektive 24, hvori der kan indsættes skaftet af et paddehatformet ventilelement 14 respektive 25, som består af et 25 elastisk materiale. Den kegleformede fortykkelse ved skaftets ende bevirker, at ventilelementet fastlåses til det navformede ventillegeme. Den læbeformede omkredskant af det tallerkenformede hoved af ventilelementet 14 respektive 25 lægger sig under det veks-30 lende tryk tætnende an mod den indvendige endeflade af det navformede ventillegeme 8 respektive 20. I dette indre område findes der flere gennemgangsboringer 13 respektive 23, som er anbragt på kranslignende måde, og via hvilke væsken kan passere ind i respek-35 tive ud fra doseringsvolumenet. Den elastiske forspæn-ding af materialet af de paddehatformede ventilelementer 14 respektive 25 er tilstrækkelig til under sta- 8 151118 bile forhold at hindre en gennemgang af væske gennem boringerne 13 respektive 23. Det er kun, hvis der optræder trykændringer, der går ud over de statiske forhold, at de læbeformede omkredskanter af ventilelementer-5 nes tallerkenformede hoveder løfter sig fra den centrale endeflade af de navformede ventillegemer 8 respektive 20, for derved at muliggøre væskestrømning.In the example shown, each valve body 8 and 20, respectively, has a central bore 12 and 24, respectively, into which the shaft of a mushroom-shaped valve element 14 and 25, respectively, consisting of a resilient material can be inserted. The cone-shaped thickening at the end of the shaft causes the valve member to lock to the hub-shaped valve body. The lip-shaped circumferential edge of the plate-shaped head of the valve member 14 and 25, respectively, seals under the alternating pressure sealingly against the inner end surface of the hub-shaped valve body 8 and 20. In this inner region, there are several passage bores 13 and 23, respectively, arranged in a coronary manner, and through which the liquid can pass into respective from the dosage volume. The elastic bias of the material of the mushroom-shaped valve elements 14 and 25, respectively, is sufficient to prevent fluid flow through the bores 13 and 23., respectively, under pressure conditions, only if pressure changes occur beyond the static, that the lip-shaped circumferential edges of the plate-shaped heads of the valve members 5 rise from the central end surface of the hub-shaped valve bodies 8 and 20, respectively, to enable fluid flow.
Foroven er slaglængden for konstruktionsenheden, der består af ventillegemet 8 og ringankeret 7, be-10 grænset af føringsrøret 61 s indvendige ansats 35.Above, the stroke of the structural unit, consisting of the valve body 8 and the ring anchor 7, is limited by the inner shoulder 35 of the guide tube 61.
Forneden bestemmes enhedens slag ved, at den nedre endekant af det navformede ventillegeme 8's del 10 -under nedadbevægelsen - støder mod den øvre ringformede endekant af det navformede ventillegeme 20's del 21.Below, the stroke of the unit is determined by the lower end edge of the portion 10 of the hub-shaped valve body 8 - during the downward movement - abutting the upper annular end edge of the portion 21 of the hub-shaped valve body 20.
15 Ved valg af længden af delene 10 og 21 kan slaglængden 30 for den bevægelige enhed 7,8- ved uændret opbygning - let ændres og indstilles nøjagtigt. Ved den mod hinanden rettede bevægelse af ventillegemerne 8 og 20 indeslutter delene 10 og 21 bælgen 15 udvendig 20 fra på formbestandig måde, så bælgen ikke kan udvide sig radialt udad.15 When selecting the length of the parts 10 and 21, the stroke length 30 of the movable unit 7,8- with unchanged structure - can be easily changed and adjusted precisely. In the reciprocal movement of the valve bodies 8 and 20, the portions 10 and 21 enclose the bellows 15 externally 20 in a shape-resistant manner so that the bellows cannot extend radially outwards.
Fig. 1 viser - hovedsagelig i originalstørrelse - delene, der indgår i en foretrukken udførelsesform, hvorved slaglængden i praksis dog snarere vælges mindre, 25 end der er vist i fig. 1. Væskemængden, der passerer ud fra studsen 27, bestemmes af antallet af pumpeslagene, som bevirkes af netfrekvensen. Denne væskemængde kan derfor indstilles nøjagtigt, idet navnlig enkeltvolumenet, der afgives for hvert pumpestød, kan indstilles 30 overordentligt nøjagtigt - selv ved en meget lille størrelse. I udleveringsafsnittet er væsken afskærmet hermetisk mod indvirkning fra luftens oxygen. Det vil ses, at konstruktionen er overordentlig enkel og billig i fremstilling, og at den arbejder meget pålideligt. Be-35 tjeningen er navnlig meget enkel og sikker og kan ikke føre til tilsmudsning af de omliggende dele.FIG. 1 shows - mainly in the original size - the parts which form part of a preferred embodiment, in which case, however, the stroke length is, in practice, rather chosen less than 25 shown in FIG. 1. The amount of fluid passing out from the plug 27 is determined by the number of pump strokes caused by the grid frequency. This amount of liquid can therefore be precisely adjusted, in particular the single volume delivered for each pump shock can be set extremely accurately - even at a very small size. In the dispensing section, the liquid is hermetically shielded from the action of the oxygen of the air. It will be seen that the design is extremely simple and inexpensive in manufacture and that it works very reliably. In particular, the Be-35 operation is very simple and safe and cannot lead to contamination of the surrounding parts.
Slagbegrænsningen kan også sikres ved hjælp af andre anslagsdele, f.eks. føringsrøret.The impact limitation can also be ensured by means of other impact components, e.g. transfer tube.

For at undgå radiale formændringer af bælgen 15 i området af den radialt indadragende fold er det fordelagtigt, såfremt der til folden eller til hver fold hører en stiv støttering i området af foldens indad-5 visende kam.In order to avoid radial shape changes of the bellows 15 in the region of the radially inwardly folding, it is advantageous if a folding or each fold has a rigid support ring in the region of the inwardly facing cam.
Det er først og fremmest særlig gunstigt, såfremt man lader foldens kam forløbe skrueformet. I dette tilfælde kan der til kammen høre et støtteelement i form af et fjederelement, som forløber skrueformet og kun kan 10 sammentrykkes aksialt, og som samtidig tjener til aksial forspænding af bælgen 15. Bælgen behøver da ikke at være formelastisk i sig selv, når blot den består af et tilstrækkeligt fleksibelt materiale.First of all, it is particularly advantageous if you let the fold of the fold go helical. In this case, the cam may comprise a support member in the form of a spring member which extends helically and can only be axially compressed, and which simultaneously serves to axially bias the bellows 15. The bellows need not then be elastic in itself when it consists of a sufficiently flexible material.
Under bestemte forudsætninger kan der også gives 15 afkald på kontraventilen 25 ved udløbssiden.Under certain conditions, 15 relief of the check valve 25 can also be given at the outlet side.
Som erstatning for kontraventilen har rummet, der omslutter pumpevolumenet, ved udløbssiden en udløbsstuds, som står i fri forbindelse med pumpevolumenet. Lysningsvidden og længden af denne udløbsstuds er di-20 mensioneret således, at den indre friktion og overfladespænding af koncentratet i udløbsstudsen er tilstrækkelig til, at koncentratsøjlen - ved uændret og ved voksende pumpevolumen - fastholdes aksialt uændret i udløbsstudsen. Det uændrede pumpevolumen befinder sig 25 i en tilstand, hvor kontraventilen 14 ved indløbssiden er lukket. Ved voksende pumpevolumen suges der koncentrat fra beholderen ind i pumpevolumenet.As a replacement for the check valve, the space enclosing the pump volume has an outlet nozzle which is in free communication with the pump volume at the outlet side. The luminous width and length of this outlet nozzle are dimensioned such that the internal friction and surface tension of the concentrate in the outlet nozzle is sufficient to maintain the concentrate column - unchanged and at increasing pump volume - axially unchanged in the nozzle. The unchanged pump volume is in a state where the check valve 14 at the inlet side is closed. With increasing pump volume, concentrate from the container is sucked into the pump volume.
Ved praktiske udførelsesformer for indretningen af denne videreudviklede type androg den indre lys-30 ningsvidde af pumpevolumenet mellem 8 og 12 mm. Slaglængden kunne indstilles mellem 1 og 2 mm. Slagfrekvensen androg 50 Hz, men kunne ændres mellem 10 Hz og 100 Hz uden forstyrrelse af driften. Der blev foretaget forsøg med væsker, der havde viskositeter på mellem 35 1 og 100 enheder (Centipoise). Kontraventilen ved ind løbssiden havde gennemgangsåbninger i form af slidser, der var anbragt i en halvcirkel, og som kunne dækkes af 10 151118 små ventilplader. Det blev konstateret, at der ved en længde på mellem 10 og 40 mm af udløbsstudsen, der erstattede udløbsventilen, og en lysningsvidde af denne studs på mellem 1 og 3 mm ikke var risiko for uddrypning 5 af koncentrat.In practical embodiments of the device of this further developed type, the internal illumination width of the pump volume was between 8 and 12 mm. The stroke length could be set between 1 and 2 mm. The stroke rate was 50 Hz, but could be changed between 10 Hz and 100 Hz without interruption of operation. Experiments were conducted with liquids having viscosities of between 35 1 and 100 units (Centipoise). The check valve at the inlet side had passage openings in the form of slots arranged in a semicircle and which could be covered by 10 small valve plates. It was found that at a length of between 10 and 40 mm of the outlet nozzle replacing the outlet valve and a luminous width of this stud of between 1 and 3 mm there was no risk of ejecting 5 of concentrate.
Uden den korsetlignende understøtning af bælgen optrådte der uregelmæssige bælgudhvælvninger, som indvirkede ugunstigt på doseringsnøjagtigheden. Med den nye korsetlignende understøtning kunne der derimod over-10 holdes volumenmæssige tolerancer af næppe målelig størrelse.Without the corset-like support of the pelvis, irregular pelvic arches appeared which adversely affected the dosage accuracy. By contrast, with the new corset-like support, volume tolerances of barely measurable size could be maintained.
Fig. 3 viser en anden udførelse af de dele, der bestemmer pumpevolumenet. I et cylindrisk hus 40, der med sin øvre ende kan sluttes til beholderen for koncen-15 tratet, er der indsat en øvre bøsning 42, som ved sin øvre ende har en udadragende flange. I den nedre ende af huset 40 findes der en tilsvarende nedre bøsning 43, som er forbundet fast med et dæksel, hvortil der hører en udløbsstuds 49. I det viste eksempel antages, at 20 den nedre bøsning 43 kan glide med spillerum i den nedre ende af huset 40. Den nedre bøsning 43 har også en udadragende flange. Mellem det nedre afsnit af huset 40 og de to studse respektive bøsninger 42 og 43, der er anbragt hovedsagelig i flugt med hinanden, 25 og som består af et stift materiale, såsom formstof, findes der er ringkammer 47. I dette ringkammer er der anbragt en spredefjeder eller forspændingsfjeder 48, der med sine to ender støtter mod flanger på bøsningerne 42 og 43, og som søger at holde de to bøs-30 ninger i den i fig. 3 viste spredestilling. I den viste udførelse er den nedre studs forbundet med en ankerring 45, der kan betjenes ved hjælp af en ikke vist elektromagnetisk indretning på en sådan måde, at den nedre studs 43 kan løftes til anlæg mod den øvre studs 35 42 for udførelse af et pumpeslag. De mod hinanden ven dende ender af de to studse er ved hjælp af en foldemembran 44 forbundet tætnende, men i hovedsagen kraft- \ 151118 11 frit med hinanden. I tilnærmelsesstillingen for de to studse 42 og 43 lukker foldemembranen 44 sig praktisk taget fuldstændigt.FIG. 3 shows another embodiment of the parts which determine the pump volume. In a cylindrical housing 40, which with its upper end can be connected to the container of the concentrate, is inserted an upper bushing 42, which at its upper end has an outwardly extending flange. At the lower end of the housing 40 there is a corresponding lower sleeve 43 which is fixedly secured to a cover to which an outlet plug 49 is attached. In the example shown, it is assumed that 20 the lower sleeve 43 can slip with clearance at the lower end. of the housing 40. The lower bushing 43 also has an outwardly extending flange. Between the lower portion of the housing 40 and the two sockets, respectively, bushings 42 and 43, which are arranged substantially in alignment with each other, 25 and which consists of a rigid material, such as plastic, there is annulus 47. In this annulus there is arranged a spreading spring or biasing spring 48 which, with its two ends, supports flanges on the bushings 42 and 43 and which seeks to hold the two bushings in the one shown in FIG. 3. In the embodiment shown, the lower stud is connected to an anchor ring 45 which can be operated by an electromagnetic device not shown in such a way that the lower stud 43 can be lifted to abut the upper stud 35 42 for performing a pump stroke. . The opposite ends of the two studs are sealed by means of a folding membrane 44, but essentially force-free with each other. In the approximation of the two studs 42 and 43, the folding membrane 44 closes practically completely.
For at hindre, at der i ringkammeret 47 skal op-5 træde trykluftkompressioner i rytme med pumpeslagbevægelserne, kan ringkammeret 47 luftes til yderatmosfæren via slidser eller boringer 50, der skal befinde sig så nær som muligt ved pumpeslagets endestilling for at opnå en kort vej for luften, som bevæges på grund af 10 ændringerne af ringkammeret 47's volumen. I det øvre flangeområde af studsen 42 findes der en ikke vist indløbsventil for pumpekammeret, hvilken ventil kan være udformet som ved den først beskrevne udføreIsesform. Slagbevægelsen for den nedre studs 43 er antydet med 15 en dobbeltpil 46. Arrangementet kan også være således, at de to studse bevæges mod og fra hinanden. Den viste udførelse har den fordel, at der ikke kan trænge koncentrat ind i ringkammeret 47. Studsen 49 kan være udformet således, at der ikke behøver at høre en kontra-20 ventil til pumpevolumenets udløb.To prevent the annular chamber 47 from having compressed air compressions in rhythm with the pump stroke movements, the annular chamber 47 can be vented to the outer atmosphere via slots or bores 50, which must be as close as possible to the pump stroke end position to obtain a short path for the air which is moved due to the 10 changes in the volume of the ring chamber 47. In the upper flange region of the plug 42 there is an inlet valve not shown for the pump chamber, which valve may be configured as in the first described embodiment. The stroke of the lower stud 43 is indicated by a double arrow 46. The arrangement may also be such that the two studs move toward and from each other. The embodiment shown has the advantage that no concentrate can enter the annulus 47. The socket 49 can be designed so that there is no need to hear a counter-valve to the pump volume outlet.
Det vil ses, at et sådant arrangement, der arbejder uafhængigt af den elastiske tilbagestillingskraft af en gummibælg, også kan dosere tilnærmelsesvis pastaformede medier, hvilket ikke kan ske med den tilbage-25 stillingskraft af et formelastisk legeme, som normalt er til rådighed. I dette tilfælde må de magnetiske kræfter opbygges tilsvarende. Analogt hermed kan fjederkraften også bestemmes.It will be seen that such an arrangement, operating independently of the resilient resilience of a rubber bellows, can also dose approximately paste-shaped media, which may not occur with the resilience of a form-elastic body normally available. In this case, the magnetic forces must be built up accordingly. Analogously, the spring force can also be determined.
Det skal sluttelig bemærkes, at man har mulighed 30 for at anvende andre drivindretninger end den elektromagnetisk arbejdende drivindretning 5, som indgår i indretningen ifølge opfindelsen. Man kan f.eks. anvende en ad pneumatisk vej cyklisk arbejdende drivindretning, der indeholder en permanent magnet, som bevæges 35 pneumatisk opad og nedad, og som indvirker på drivindretningens anker.Finally, it should be noted that it is possible to use 30 drives other than the electromagnetically acting drive 5 which is included in the device according to the invention. One can, for example. use a cyclic working drive device by pneumatic path which includes a permanent magnet which is moved pneumatically upwards and downwards and which acts on the drive device's anchor.
