Description

       

   <Desc/Clms Page number 1> 
 



  "Robinet rotatif pour le débit de liquides sous pression" 
Cette invention concerne un robinet rotatif pour le débit de liquides sous pression, entre autre de boissons et plus particulièrement de la bière, et essentiellement constitué d'un corps central   91i   présente : a) un conduit d'entrée du liquide sous pression et un conduit de sortie à l'air libre ; b) un boisseau cylindrique ou sphérique logé dans une chambre cylindrique ou sphérique   enserré-entre des   pièces latérales et présentant un passage peur permettre l'écoulement du liquide sous pression entre les conduits d'entrée et de sortie de ce liquide ; c) une manette d'actionnement du boisseau précité, prolongée par une pièce en forme d'étrier. 



   Des robinets comportant des éléments constitutifs tels qu'énoncés ci-dessus ou techniquement équivalents sont connus. 



   Un but de l'invention est de remédier aux inconvénients que peuvent présenter ces robinets, inconvénients qui se résument essentiellement   couse   détaillés ci-dessous : 1. Par manque de trou d'air et sous pression atmosphérique, une quantité non négligeable de liquide ne s'échappe pas complètement du robinet après chaque fermeture de celui-ci. La vidange du conduit de sortie ne se fait que goutte à goutte et dure un certain temps qui est généralement trop long. 



  2. Lorsqu'un orifice pour permettre l'entrée d'air, en 

 <Desc/Clms Page number 2> 

 position fermée du robinet, est prévu autour du boisseau le joint assurant l'étanchéité autour du trou d'air ne peut être atteint qu'en démontant totalement le robinet. 



  3. Dans les conditions exposées au point 2 un canal à air n'est jamais entièrement situé en dehors du circuit sous pression du liquide. 



   Pour remédier aux inconvénients des robinets existants détaillés ci-dessus le robinet salon l'invention est caractérisé en ce que dans le corps du robinet précité, en dehors de la chambre cylindrique ou sphérique précitée, est ménagé un canal qui met en communication l'air extérieur avec le conduit de sortie précité un orifice étant ménagé dans la pièce latérale adjacente pour alternativement correspondre avec le canal précité, en position fermée du robinet, et s'en écarter, en position ouverte de celui-ci. 



   Dans une forme de réalisation caractéristique de l'invention le passage précité permettant l'écoulement du liquide au travers du boisseau précité est un passage coudé selon un angle qui correspond à celui que forment entre eux les conduits d'entrée et de sortie précités. 



   Une caractéristique particulière du robinet réside dans le fait qu'un passage additionnel s'entend radialement au travers du boisseau précité pour mettre en communication le conduit d'entrée avec le passage coudé précité, dans la position dans laquelle la communication entre les conduits d'entrée et de sortie est interrompue et cela dans le but d'équilibrer la pression en amont avec celle qui règne dans le passage coudé. 



   D'autres détails et avantages de l'invention ressortiront de la description qui sera donnée ci-après d'un robinet pour le débit de liquides 

 <Desc/Clms Page number 3> 

 sous pression selon l'invention. Cette description n'est donnée qu'à titre d'exemple et ne limite pas l'invention. Les notations de référence se rapportent aux figures ci-jointes. 



   La figure 1 est une vue en coupe longitudinale du robinet selon l'invention, en position fermée. 



   La figure 2 est une vue analogue du robinet, en position ouverte. 



   La figure 3 est une vue en coupe selon la ligne III-III de la figure 1. 



   Le robinet représenté par ces figures est essentiellement constitué par un corps qui comprend un conduit d'entrée 2 pour le liquide sous pression et de sortie 3 pour le liquide à l'air libre. 



   Entre ces deux conduits est logé le boisseau 4 qui est actionné entre les positions "ouverte"et"fermée"par la manette 5. Cette manette 5 est prolongée par une pièce en forme d'étrier 6 qui, de plus, est enserrée entre deux pièces latérales 7 qui complètent le corps central 1 du robinet. Des vis à tête noyée 8 solidarisent le boisseau 3 de la pièce en forme d'étrier 6 et les pièces latérales 7. 



   Une rotation de la manette provoque we rotation correspondante des éléments qui viennent d'être décrits. 



   Le boisseau 4 est traversé par un passage coudé 9 qui met en communication les conduits d'entrée 2 et de sortie 3, lorsque le robinet est en position"ouverte". En position"fermée"la communication entre les conduits 2 et 3 est évidemment interrompue. Cette position est représentée à la figure 1. Des joints toriques 10 et 11 assurent l'étanchéité indispensable entre le boisseau 4 et le conduit de sortie 3, d'une part, et entre le boisseau 4 et le 

 <Desc/Clms Page number 4> 

 corps central 1 du robinet, d'autre part. Un autre joint torique,   il,   est prévu plus en aval à hauteur d'un ajutage 12 qui maintient le bec verseur 13 du robinet. 



   Le canal 14 qui caractérise essentiellement l'invention, est ménagé en dehors du boisseau 4, canal dont une extrémité débouche dans le conduit de sortie 3 tandis que l'autre débouche latéralement dans le corps central 1 du robinet face à un trou 15 ménagé dans la pièce latérale adjacente 7, en position"fermée"du robinet. Cette position est représentée à la figure 3 où l'on remarque la présence d'un petit joint torique 16. Il est à remarquer que le canal 14 est fixe dans le corps tandis que le trou 15 tourne avec la pièce latérale 7. 



   Pour mettre le robinet en position ouverte il faut faire tourner la manette 5 et la pièce 7 qui lui est solidaire, ce qui déplace le trou 15. 



  Donc en position ouverte le canal 14 ne débouche plus vis à vis du trou 15 (qui a tourné) mais devant la pièce 7, le canal 14 est ainsi obturé et le joint torique 16 assure l'étanchéité du canal 14 pendant que le robinet débite. 



   La disposition du canal 14 en dehors du boisseau 4 met donc celui-ci en dehors du circuit du liquide sous pression. L'accès à son joint torique 16 est extrêmement aisé. Le démontage du robinet proprement dit n'est donc pas requis pour le remplacement de ce joint torique 16. 



   Enfin, dans le but de réaliser un mélange intime du liquide adhérant au boisseau avec le liquide sous pression, le boisseau du robinet selon l'invention présente un passage additionnel 19 qui met le passage coudé 9 en communication avec le liquide sous pression en amont du boisseau 4. 

 <Desc/Clms Page number 5> 

 



   De la description qui vient   d'drue   donnée il résulte qu'une solution efficace est fournie aux divers problèmes que pose l'entretien d'un robinet du type décrit ci-dessus.

  "Rotary valve for the flow of pressurized liquids"
This invention relates to a rotary valve for the flow of pressurized liquids, inter alia drinks and more particularly beer, and essentially consisting of a central body 91i has: a) an inlet pipe for the pressurized liquid and a conduit air outlet; b) a cylindrical or spherical plug housed in a cylindrical or spherical chamber clamped-between side pieces and having a passage to allow the flow of liquid under pressure between the inlet and outlet conduits of this liquid; c) a lever for actuating the above-mentioned plug, extended by a stirrup-shaped part.



   Valves comprising constituent elements as stated above or technically equivalent are known.



   An object of the invention is to remedy the drawbacks that these taps can have, drawbacks which are essentially summed up in detail below: 1. By lack of air hole and under atmospheric pressure, a non-negligible quantity of liquid does not '' does not escape completely from the tap after each closing of it. The draining of the outlet pipe is only done drop by drop and lasts a certain time which is generally too long.



  2. When an orifice to allow the entry of air,

 <Desc / Clms Page number 2>

 closed position of the tap, is provided around the plug the seal ensuring the seal around the air hole can only be reached by completely dismantling the tap.



  3. Under the conditions set out in point 2, an air channel is never entirely located outside the circuit under liquid pressure.



   To overcome the drawbacks of the existing taps detailed above, the living room tap the invention is characterized in that in the aforementioned tap body, apart from the aforementioned cylindrical or spherical chamber, a channel is formed which places the air in communication outside with the aforementioned outlet conduit an orifice being formed in the adjacent lateral part to alternately correspond with the aforementioned channel, in the closed position of the valve, and to deviate therefrom, in the open position thereof.



   In a characteristic embodiment of the invention the aforementioned passage allowing the liquid to flow through the aforementioned plug is a bent passage at an angle which corresponds to that formed between them the aforementioned inlet and outlet conduits.



   A particular characteristic of the tap resides in the fact that an additional passage is understood radially through the aforementioned plug to put in communication the inlet conduit with the aforementioned bent passage, in the position in which the communication between the conduits inlet and outlet is interrupted and this in order to balance the pressure upstream with that prevailing in the bent passage.



   Other details and advantages of the invention will emerge from the description which will be given below of a tap for the flow of liquids.

 <Desc / Clms Page number 3>

 under pressure according to the invention. This description is given by way of example only and does not limit the invention. The reference notations refer to the attached figures.



   Figure 1 is a longitudinal sectional view of the valve according to the invention, in the closed position.



   Figure 2 is a similar view of the valve, in the open position.



   Figure 3 is a sectional view along line III-III of Figure 1.



   The valve represented by these figures essentially consists of a body which comprises an inlet pipe 2 for the liquid under pressure and an outlet pipe 3 for the liquid in the open air.



   Between these two conduits is housed the plug 4 which is actuated between the "open" and "closed" positions by the handle 5. This handle 5 is extended by a piece in the shape of a stirrup 6 which, moreover, is clamped between two side pieces 7 which complete the central body 1 of the tap. Countersunk screws 8 secure the plug 3 of the stirrup-shaped part 6 and the lateral parts 7.



   A rotation of the lever causes the corresponding rotation of the elements which have just been described.



   The plug 4 is crossed by a bent passage 9 which connects the inlet 2 and outlet 3 conduits, when the valve is in the "open" position. In the "closed" position the communication between the conduits 2 and 3 is obviously interrupted. This position is shown in Figure 1. O-rings 10 and 11 provide the essential seal between the plug 4 and the outlet conduit 3, on the one hand, and between the plug 4 and the

 <Desc / Clms Page number 4>

 central body 1 of the tap, on the other hand. Another O-ring, it, is provided further downstream at the height of a nozzle 12 which holds the spout 13 of the tap.



   The channel 14, which essentially characterizes the invention, is formed outside of the plug 4, a channel one end of which opens into the outlet conduit 3 while the other opens laterally into the central body 1 of the valve facing a hole 15 formed in the adjacent side piece 7, in the "closed" position of the valve. This position is shown in FIG. 3 where we note the presence of a small O-ring 16. It should be noted that the channel 14 is fixed in the body while the hole 15 rotates with the lateral part 7.



   To put the valve in the open position, turn the handle 5 and the part 7 which is integral with it, which moves the hole 15.



  So in the open position the channel 14 no longer opens with respect to the hole 15 (which has turned) but in front of the part 7, the channel 14 is thus closed and the O-ring 16 ensures the sealing of the channel 14 while the tap is delivering .



   The arrangement of the channel 14 outside the plug 4 therefore puts the latter outside of the circuit of the pressurized liquid. Access to its O-ring 16 is extremely easy. Disassembly of the valve itself is therefore not required for the replacement of this O-ring 16.



   Finally, in order to achieve an intimate mixture of the liquid adhering to the plug with the pressurized liquid, the valve plug according to the invention has an additional passage 19 which places the bent passage 9 in communication with the pressurized liquid upstream of the bushel 4.

 <Desc / Clms Page number 5>

 



   From the description which has just been given, it follows that an effective solution is provided to the various problems posed by the maintenance of a tap of the type described above.
