The appliance has at least one indexing device 2c-2d capable of interacting with at least one complementary part 1e-5 formed directly on or attached to the female tubular element 1 being shaped to ensure blocking of the tube 2 heightwise as required according to a position corresponding to a predetermined and calibrated quantity of the product to be sampled.

Description

L'addition, conformEment au brevet principal, concerne un appareil pour aspirer et refouler un fluide, notamment liquide. Addition, according to the main patent, relates to an apparatus for sucking and discharging a fluid, in particular liquid.

L'addition se rattache au secteur technique des moyens de pompage en général. The addition is related to the technical sector of pumping means in general.

On rappelle que selon le brevet principal, on a voulu baliser un appareil conformé pour permettre de pr6-rXgler une quantité variable quelconque de liquide de fanon à pouvoir ef fectuer plusieurs prélèvements successifs correspondant au réglage choisi, sans entre obligé de contrbler à chaque fois la quantité prélevée
A cet effet, l'appareil est remarquable en ce qu'il comprend un corps tubulaire dans lequel est monté avec capacité de coulissement un second corps tubulaire ; à l'intérieur du second corps est monté axialement et à libre coulissement, un organe de manoeuvre présentant en bout un piston susceptible de coopérer avec l'alésage du premier corps femelle de sorte qu'en fonction du positionnement variable en hauteur du second corps tubulaire à l'intérieur du corps femelle, le piston se trouve à une certaine distance d'un ajutage formé dans le fond du corps femelle pour correspondre à la quantité de liquide désirée que l'on prélève par aspiration dans une chambre dudit corps résul- tnt du positionnement relatif des deux corps tubulaires, l'or- gane de manoeuvre 'étant rappelé automatiquement en position par un ressort
Selon l'addition, à partir de cette conception de base, on a voulu encore améliorer les caractéristiques de lap- pareil, notamment pouvoir régler à volonté, d'une manière bien précise et indéréglable, une quantité variable de produit à prélever En effet, pour certains produits spéci+iques, il est né-' cessaire et absolu que la dose prélevée corresponde très exactement aux prescriptions de quantité imposées
Dans ce but, le corps tubulaire dans lequel coulisse la tige du piston, présente un moyen d'indexation susceptible de coopérer, avec au moins une partie complémentaire formée sur le corps tubulaire femelle, ladite partie étant formée à une distance (xl) du fond du corps femelle tandis que le moyen d'inde- xation est disposé par rapport à l'extrémité du piston en appui sur son siège, à une distance (x2) égale, en position d'indexa- tion, à la différence entre (xl) et la distance (x) entre l'ex- trémité dudit piston et le fond du corps femelle, correspondant à la quantité désirée et étalonnée de produit à prélever
Ces caractéristiques sont décrites ci-après en référence aux figures des dessins dans lesquelles
la figure 1 est une vue en perspective de l'appareil selon l'addition,
la figure 2 est une vue en coupe longitudinale de l'appareil indexé en position minimum de prélèvement,
la figure 3 est une vue semblable à la figure 2 en position de prélèvement maximum,
la figure 4 est une vue en coupe partielle illustrant une variante de réalisation
On rappelle pour - une meilleure compréhension de la description, que l'appareil comprend un corps ou élément tubulaire femelle (1 > recevant à libre coulissement un tube coaxial ( A l'intérieur du tube (2) est montée une tige coulissante (3 > recevant en bout et en débordement, un piston (4) coopérant dans l'alésage du tube (1). Une collerette circulaire de préhen- sion (lc) est formé en débordement de la partie supérieure du tube (1)
Selon l'addition, le tube (?) présente en débordement un moyen d'indexation (2C), sous forme d'un ergot par exemple, coopérant avec des parties complémentaires (le) formés sur le corps tubulaire (
Par exemple, ces parties (le) sont des échancrures formées dans l'épaisseur du tube (1) et transversalement à partir d'une lumière (lf) dans laquelle peut coulisser l'ergot (2c) u fur et a mesure de lenfoncement du tube C2) à l'intérieur du tube (1).La lumière (1f) est rectiligne libre des dessins) ou éventuellement hélicoïdale et est formée en fonction de l'extré- mité supérieure du tube (1), Chaque échancrure (le) correspond a une graduation compte-tenu de la quantité de produit a prélever
D'une manière importante, l'échancrure inférieure
(le) est située à une distance (xl) du fond du corps (1) tandis que l'ergot (2c) est disposé par rapport à l'extrémité du piston (g) en position d'appui sur son siège, à une distance (x2).Cette distance (x2), en position d'indexation de l'ergot dans l'échancrure correspondante, est égale à la différence entre
(x1) et la distance (x), entre l'extrémité du piston (43 et le fond du corps (1), ce qui correspond à une quantité étalonnée de produit à prélever.It is recalled that according to the main patent, it was desired to mark a shaped apparatus to allow pre-adjust any variable amount of dewax liquid to be able to make several successive samples corresponding to the chosen setting, without having to check every time the quantity withdrawn
For this purpose, the apparatus is remarkable in that it comprises a tubular body in which is mounted with sliding capacity a second tubular body; inside the second body is mounted axially and freely sliding, an actuator having at the end a piston capable of cooperating with the bore of the first female body so that depending on the variable positioning in height of the second tubular body inside the female body, the piston is at a distance from a nozzle formed in the bottom of the female body to correspond to the desired quantity of liquid which is taken by suction in a chamber of said body. relative positioning of the two tubular bodies, the actuating organ being automatically recalled in position by a spring
According to the addition, from this basic design, it has been desired to further improve the characteristics of the device, in particular to be able to adjust at will, in a very precise and foolproof manner, a variable quantity of product to be sampled. for certain specific products it is necessary and absolute that the dose taken corresponds exactly to the quantity requirements imposed.
For this purpose, the tubular body in which the piston rod slides, has an indexing means capable of cooperating, with at least one complementary portion formed on the female tubular body, said portion being formed at a distance (xl) from the bottom of the female body while the means of inde- xation is disposed relative to the end of the piston resting on its seat, at a distance (x2) equal, in the indexing position, to the difference between (xl ) and the distance (x) between the end of said piston and the bottom of the female body, corresponding to the desired and calibrated quantity of product to be sampled
These characteristics are described below with reference to the drawing figures in which
FIG. 1 is a perspective view of the apparatus according to the addition,
FIG. 2 is a longitudinal sectional view of the apparatus indexed in the minimum sampling position,
FIG. 3 is a view similar to FIG. 2 in the maximum sampling position,
FIG. 4 is a partial sectional view illustrating a variant embodiment
It is recalled for - a better understanding of the description, that the apparatus comprises a body or female tubular element (1> receiving a sliding coaxial tube (inside the tube (2) is mounted a sliding rod (3> receiving end and overflow, a piston (4) cooperating in the bore of the tube (1) A circular gripping flange (1c) is formed in overflow of the upper part of the tube (1)
According to the addition, the tube (?) Has overflow an indexing means (2C), in the form of a lug for example, cooperating with complementary parts (1c) formed on the tubular body (
For example, these parts (1c) are notches formed in the thickness of the tube (1) and transversely from a lumen (1f) in which the pin (2c) can slide as and when the tube C2) inside the tube (1). The light (1f) is rectilinear free of the drawings) or possibly helical and is formed according to the upper end of the tube (1), each notch (the) corresponds to a graduation taking into account the quantity of product to be sampled
Importantly, the lower indentation
(le) is located at a distance (xl) from the bottom of the body (1) while the lug (2c) is arranged relative to the end of the piston (g) in the support position on its seat, at a distance distance (x2) .This distance (x2), in indexing position of the lug in the corresponding notch, is equal to the difference between
(x1) and the distance (x), between the end of the piston (43 and the bottom of the body (1), which corresponds to a calibrated amount of product to be taken.

Dans le cas de l'échancrure inférieure, la distance (x > correspond à la dose de quantité minimum de produit à prélever. Conséquemment, chaque échancrure est séparée d'une distance (x >
La lumière (1f) est disposée au dessus du piston 3) en position haute, c'est-à-dire en position de prélèvement maxi ou l'ergot (2c) est indexé dans l'échancrure supérieure d'extrémité. En regard de chaque échancrure (le) peuvent entre inscrites les graduations correspondant aux différentes quantités possi bleus de produit à prélever.In the case of the lower indentation, the distance (x> corresponds to the dose of minimum quantity of product to be sampled, consequently each indentation is separated by a distance (x>
The light (1f) is disposed above the piston 3) in the upper position, that is to say in the maximum sampling position or the lug (2c) is indexed in the upper end notch. In front of each notch (the) can between entered the graduations corresponding to the possible possible quantities of product to be taken.

En fonction de la quantité nécessaire de produit a prélever dans la chambre ou réservoir (1b) du tube (13, il suffit d'agir en poussée sur le tube (2) et d'amener l'ergot (2c) qui coulisse librement dans la lumière (1f), dans l'échancrure (le) correspondante en vue de l'indexation en hauteur dudit tube (2). On agit alors comme indiqué dans le brevet, sur la tige du piston (.7. > . Depending on the necessary quantity of product to be taken from the chamber or reservoir (1b) of the tube (13, it is sufficient to act in thrust on the tube (2) and to bring the pin (2c) which slides freely in the light (1f) in the corresponding indentation (1c) for indexing the height of said tube (2), and then acting as indicated in the patent on the piston rod (7).

On souligne que les distances entre chaque échancrure et positionnement (le) et le fond du tube (13 sont rigoureuse- ment calculées et étalonnées pour correspondre a une quantité précise de produit à prélever A noter également, qu'au cours de différentes manipulatons en vue de prélever toujours la mêe quantité de produit affiché, il n'est pas possible de dérégler accidentellement lindexation étant donné que les échancrures, en combinaison avec la lumière, constituent un crantage en hautueur
Eventuellement, pour des applications spécifiques, une seule échancrure peut être nécessaire.It is pointed out that the distances between each indentation and the positioning (the) and the bottom of the tube (13 are rigorously calculated and calibrated to correspond to a precise quantity of product to be sampled. Note also that during different manipulatons in order to to always take the same quantity of product displayed, it is not possible to accidentally disregard the indexing since the indentations, in combination with the light, constitute a notch in height
Optionally, for specific applications, only one indentation may be necessary.

Des varianes de réalisation des moyens d'indexation peuvent entre prévus sans pour cela sortir du cadre de linven- tion.  Variations of realization indexing means can between expected without departing from the framework of linvention.

On en a illustré un exemple à la figure 4 ou le corps tubulaire (7) présente des empreintes en creux du type cannelures (2d) par exemple, espacées de la distance (x) correspondant à la quantité de liquide à prélever et coopérant avec un organe complémentaire souple ou escamotable rapporté dans le corps tubulaire femelle (1 > , par exemple sous la forme d'une rondelle élastique (5) collée sur la collerette (le) et dont le diamètre intérieur est inférieur au diamètre extérieur du corps (2 > afin de bloquer ledit corps (2) dans la position choisie, tout en permettant le coulissement d'une indexation à l'autre par application d'une force complémentaire pour vaincre la résistance de l'indexation.  An example has been illustrated in FIG. 4 where the tubular body (7) has indentations of the groove type (2d) for example, spaced apart by the distance (x) corresponding to the quantity of liquid to be taken and cooperating with a complementary flexible or retractable member reported in the female tubular body (1>, for example in the form of a spring washer (5) glued to the flange (1c) and whose inner diameter is smaller than the outer diameter of the body (2> in order to lock said body (2) in the chosen position, while allowing the sliding of an indexing to the other by applying a complementary force to overcome the resistance of the indexing.
