Abstract

The control, for equipment which uses compressed air or water at pressure with a fine grained abrasive material to clean contaminated surfaces, is mounted on a single hand held pistol with trigger (2) which incorporates a mixer and nozzle (3). Water at high pressure is delivered to the pistol (2) through a pump (1) and pipe (E1). An air compressor (4) supplies air to a material tank (6) and sends an air/material mixture to the mixer (3) by Venturi effect. Water is controlled by the pistol trigger and a lever on the same pistol controls the flow of material using a tank valve (V1) and pipe (A7).

Description

La présente invention concerne un dispositif de commande d'une installation de nettoyage de surfaces contaminées au moyen d'un jet composé d'air, d'une matière de projection à grain fin et d'un liquide, ladite installation comprenant un compresseur d'air, un réservoir contenant la matière de projection mis sous pression par ledit compresseur, un appareil d'alimentation et mise sous pression dudit liquide, ledit dispositif de commande étant une poignée munie d'une gâchette commandant l'arrivée ou l'arrêt du liquide sous pression dans un dispositif muni d'une buse et également alimenté par la matière de projection mélangée avec l'air comprimé.The present invention relates to a device for control of a surface cleaning installation contaminated with a jet of air, a fine-grained projection material and a liquid, said installation comprising an air compressor, a tank containing the projection material placed under pressure by said compressor, an apparatus supply and pressurization of said liquid, said control device being a handle provided a trigger controlling the arrival or stop of the pressurized liquid in a device fitted with a nozzle and also supplied with spray material mixed with compressed air.

Il est connu depuis plusieurs années l'utilisation d'installations pour le nettoyage de surfaces, notamment de façades d'immeubles ou de monuments contaminées volontairement (grafitis) ou involontairement par la pollution atmosphérique, voire le passage du temps. De telles installations comprennent essentiellement l'utilisation d'un jet d'air sous pression comprenant une matière de projection à grain fin et l'utilisation d'un liquide qui est, la plupart du temps, de l'eau claire. L'installation comprend donc un compresseur d'air alimentant un réservoir dans lequel se trouve la matière à projeter et un surpresseur d'eau, le liquide et l'air comprimé avec la matière de projection arrivant dans un dispositif comprenant une buse permettant de projeter un jet contre la surface à décontaminer. It has been known for several years the use facilities for cleaning surfaces, including facades of buildings or monuments voluntarily contaminated (grafitis) or unintentionally by air pollution or even the passage of time. Such facilities basically include the use of a jet pressurized air comprising a material of fine grain projection and the use of a liquid which is mostly clear water. The installation therefore includes an air compressor supplying a tank in which the material to be sprayed and a water booster, the liquid and compressed air with the projection material arriving in a device comprising a nozzle allowing to project a jet against the surface to decontaminate.

Un des avantages de ce procédé est le fait qu'il n'utilise pas de matières chimiques dont l'élimination pose des problèmes complémentaires.One of the advantages of this process is the fact that it does not use chemicals whose elimination poses additional problems.

On a apporté des améliorations concernant la construction de la buse afin de donner au jet des propriétés mécaniques améliorant la décontamination des surfaces, ainsi qu'aux différents procédés déterminant la pression optimale et le mélange réfrigérant air et matière de projection. Il est évident que lorsqu'il s'agit de nettoyer des surfaces qui s'étalent sur plusieurs mètres de hauteur, les appareils relativement lourds tels que le compresseur, le surpresseur d'eau, le réservoir se trouvent au sol ou sur un véhicule qui se déplace, tandis qu'une personne tient un dispositif de projection qui se présente sous la forme d'une poignée à travers laquelle on commande essentiellement l'arrivée d'eau. L'arrivée de l'air avec la matière de projection est commandée par une commande de sécurité dite "homme mort" actionnée en permanence par l'utilisateur pour permettre l'arrêt de l'arrivée de l'air sous pression. Cette double commande pour le liquide et air comprimé que l'on trouve dans plusieurs installations de ce type est relativement encombrante et rend difficile le travail, notamment lorsqu'on se trouve sur des échaffaudages. Le réglage de la pression du circuit pneumatique, ainsi que du débit de la matière à projeter se fait par un opérateur resté près du réservoir.Improvements have been made to the construction of the nozzle in order to give the jet mechanical properties improving the decontamination of surfaces, as well as to the various determining processes the optimal pressure and the air coolant mixture and projection material. It is obvious that when is to clean surfaces that spread over several meters in height, the devices relatively heavy such as the compressor, the water booster, the tank are on the ground or on a vehicle that moves while a person is holding a device projection which is in the form of a handle through which you basically control the water supply. The arrival of air with the matter of projection is controlled by a safety command called "dead man" permanently activated by the user to allow the arrival of pressurized air. This double command for the liquid and compressed air found in many installations of this type is relatively bulky and makes work difficult, especially when found on scaffolding. Pressure adjustment of the pneumatic circuit, as well as the flow of the material to be sprayed is done by an operator who remains close of the tank.

Le but de la présente invention est de proposer un dispositif de commande pour une telle installation permettant d'améliorer les conditions de travail sans diminuer l'efficacité des mesures de sécurité et diminuer les coûts d'utilisation de l'installation. The purpose of the present invention is to provide a control device for such an installation improving working conditions without decrease the effectiveness of security measures and reduce the costs of using the installation.

Le dispositif de commande selon la présente invention est caractérisé par le fait que ledit dispositif de commande est muni d'un organe de commande contrôlant le dispositif d'alimentation et de purge en air comprimé dudit réservoir, ledit organe comprenant un élément de mise en état de fonctionnement dudit organe et un dispositif de mise en action commandé par ladite gâchette.The control device according to the present invention is characterized in that said device for control is provided with a control member controlling the compressed air supply and purge device of said reservoir, said member comprising an element of put into working condition of said organ and a actuation device controlled by said trigger.

L'avantage du dispositif de commande selon la présente invention est le fait que la commande de circuit pneumatique, plus précisément la mise sous pression et la purge du réservoir est commandée à distance directement par la même gâchette qui commande le liquide.The advantage of the control device according to the present invention is the fact that circuit control pneumatic, more specifically pressurization and the tank drain is remotely controlled directly by the same trigger which controls the liquid.

Pour permettre de neutraliser l'arrivée d'air et conserver uniquement la projection du liquide, le dispositif comprend d'abord un élément de mise en état de fonctionnement de l'organe et un contacteur qui vient en deuxième position pour permettre la mise en action de l'organe.To neutralize the air intake and keep only the liquid projection, the device first includes a conditioner of operation of the organ and a contactor which comes in second position to allow the setting organ action.

Selon une variante d'exécution, ledit organe est purement pneumatique et selon une variante préférée d'exécution, il comprend deux distributeurs pneumatiques, dont le premier est muni d'un interrupteur du type à bascule et le deuxième d'un contacteur sous la forme d'une bille.According to an alternative embodiment, said member is purely pneumatic and according to a preferred variant of execution, it includes two distributors tires, the first of which is fitted with a rocker type switch and the second one contactor in the form of a ball.

L'organe de commande pourrait également être purement électrique et, dans ce cas, il suffirait de disposer d'un interrupteur électrique suivi d'un contacteur actionné par la gâchette. The controller could also be purely electric and, in this case, it would suffice to have an electric switch followed by a contactor trigger operated.

Dans ce type d'installation, on utilise plus volontiers le circuit de commande pneumatique en évitant l'alimentation électrique pour des raisons évidentes de sécurité, notamment à cause de la présence de liquide.In this type of installation, we use more readily the pneumatic control circuit avoiding power supply for obvious reasons of safety, especially because of the presence of liquid.

La présente invention propose également d'autres améliorations rendant plus facile la commande de l'installation et moins onéreuse, au moins sur le plan de l'utilisation.The present invention also provides other improvements making it easier to order installation and less expensive, at least in terms of of use.

En effet, en fonction de l'état de contamination de la surface, il est quelquefois nécessaire de régler la pression du circuit pneumatique et, dans ce cas, une personne doit se trouver près du réservoir pour effectuer ce travail en fonction des indications données par la personne qui effectue le traitement de la surface à décontaminer. Cette manière de procéder présente l'inconvénient de devoir faire appel à une deuxième personne ou prévoir que la personne qui effectue le traitement arrête son travail pour aller effectuer ces réglages et revenir.Indeed, depending on the contamination state of the surface, it is sometimes necessary to adjust the pressure of the pneumatic circuit and, in this case, a no one should be near the tank to perform this work as directed data by the person carrying out the processing of the surface to be decontaminated. This way of proceeding has the disadvantage of having to call upon a second person or provide that the person who performs treatment stops work to go make these settings and return.

En utilisant soit un circuit électrique, soit de préférence pneumatique, un régulateur de pression est également installé sur le dispositif de commande, ce qui permet à l'utilisateur de connaítre la pression du circuit pneumatique et la modifier à volonté.Using either an electrical circuit or preferably pneumatic, a pressure regulator is also installed on the control device, this which allows the user to know the pressure of the pneumatic circuit and modify it at will.

Un autre élément qui peut également être selon une variante d'exécution incorporé au dispositif de commande est une commande du dispositif réglant le débit de la matière de projection. Cette commande peut être électrique, mais elle est, de préférence, pneumatique pour les mêmes raisons que précédemment. Another element which can also be according to a variant embodiment incorporated into the command is a command of the device regulating the projection material flow. This command can be electric, but it is, preferably, pneumatic for the same reasons as above.

L'invention sera maintenant décrite plus en détail à l'aide du dessin annexé.The invention will now be described in more detail at using the attached drawing.

La figure 1 est une vue tout à fait schématique d'une installation utilisant la commande selon la présente invention.Figure 1 is a completely schematic view of a installation using the command according to this invention.

La figure 2 est une vue éclatée et de côté du dispositif de commande selon la présente invention.Figure 2 is an exploded side view of the control device according to the present invention.

La figure 3 est une vue schématique de côté du dispositif de commande.Figure 3 is a schematic side view of the control device.

La figure 4 est une vue en plan de la partie inférieure du dispositif de commande selon la présente invention.Figure 4 is a plan view of the bottom of the control device according to the present invention.

A la figure 1, on a représenté de manière tout à fait schématique les principaux éléments d'une installation de décontamination de surfaces munis du dispositif de commande selon la présente invention.In Figure 1, there is shown quite schematic the main elements of an installation for decontamination of surfaces fitted with the control according to the present invention.

Une alimentation en eau E passe dans un dispositif de surpression 1 et à travers un tuyau E1 alimente le dispositif de commande 2, lequel au moyen d'une gâchette commande le passage ou l'arrêt d'eau vers un dispositif de mélange 3.A water supply E passes through a device for overpressure 1 and through a pipe E1 feeds the control device 2, which by means of a trigger controls the passage or stopping of water to a mixing device 3.

Un compresseur d'air 4 alimente à travers un tuyau A1 un assécheur d'air 5. A travers un tuyau A2 l'air ainsi asséché passe d'abord à travers un dispositif de régulation de pression d'air R1 et par la suite il est dirigé par un tuyau A5 dans une cuve de pression 6 à travers une vanne de remplissage V1. Le réservoir 6 contient un produit de projection présentant des grains fins utilisés pour le nettoyage des surfaces. Un autre tuyau A3 conduit l'air asséché à la sortie du réservoir 6 munie d'une vanne V2 à travers laquelle le produit de projection est poussé grâce à la pression subsistant dans le réservoir, et l'aspiration (effet Venturi) dans le tuyau A4. Ainsi à travers un tuyau A4, le produit à projeter est mélangé avec l'air comprimé et arrive au dispositif de mélange 3 muni d'une buse, à travers laquelle est projeté contre la surface à décontaminer.An air compressor 4 feeds through a pipe A1 an air dryer 5. Through a pipe A2 the air thus dried out first passes through a device for regulation of air pressure R1 and thereafter it is directed by an A5 pipe in a pressure tank 6 to through a filling valve V1. The tank 6 contains a projection product with grains purposes used for cleaning surfaces. Another pipe A3 leads the dried air out of the tank 6 provided with a valve V2 through which the product of projection is pushed thanks to the remaining pressure in the tank, and the suction (Venturi effect) in the A4 pipe. Thus through an A4 pipe, the product to spray is mixed with compressed air and arrives at the mixing device 3 provided with a nozzle, through which is projected against the surface to be decontaminated.

Un autre tuyau A6 fournit l'air asséché au dispositif de commande 2. L'air ainsi arrivé est utilisé pour commander à travers un organe approprié et un tuyau A7, la vanne V1 de mise sous pression du réservoir 6, ou de purge. La vanne V1 est agencée pour soit mettre sous pression le réservoir, soit la purger.Another hose A6 supplies the dried air to the device 2. The air thus arrived is used for order through an appropriate device and A7 pipe, the valve V1 for pressurizing the tank 6, or purge. The valve V1 is arranged to either put under pressure the tank, or purge it.

Selon une variante préférée d'exécution, la commande 2 est munie d'un dispositif de mesure et de régulation à distance de la pression du circuit pneumatique. Dans ce but, on agit sur le régulateur de pression R1 (à travers un tuyau A9) au moyen d'un régulateur R2 dont est équipé le dispositif de commande 2.According to a preferred variant of execution, the command 2 is fitted with a measurement and regulation device distance from the pneumatic circuit pressure. In this goal, we act on the pressure regulator R1 (at through a pipe A9) by means of a regulator R2 of which is equipped with the control device 2.

Selon une autre variante d'exécution, il est prévu de pouvoir commander le débit de la matière de projection à travers la vanne V2. Dans ce but, à travers un double tuyau A8 et un organe approprié se trouvant sur le dispositif de commande 2, on règle le débit du produit passant à travers la vanne V2.According to another alternative embodiment, provision is made for ability to control flow of spray material through valve V2. For this purpose, through a double hose A8 and a suitable member located on the control device 2, the product flow is adjusted passing through valve V2.

Nous nous occuperons maintenant plus en détail de la partie de l'installation 2, ainsi que des différents organes de commande pneumatiques. We will now deal in more detail with the part of installation 2, as well as the different pneumatic controls.

A la figure 2, nous avons représenté vu de côté le dispositif de commande 2 de manière schématique. Il s'agit d'une poignée 201 munie d'une gâchette 202 qui commande au moyen d'un interrupteur à ressort ou à piston conventionnel de type connu, la sortie du liquide à travers l'orifice 203 de la commande 2. L'alimentation en liquide se fait à travers la ligne E1. L'orifice 203 est habituellement connecté à un dispositif de dérivation 204 en forme de T. Les deux autres extrémités du T sont reliées à un robinet T1, respectivement T2. Le robinet T1 permet de commander l'alimentation avec le liquide du dispositif de mélange 3. Ce dispositif de mélange 3 est alimenté par l'air comprimé à travers le tuyau d'air A4. Le deuxième robinet T2 est relié à un raccord coudé 205 muni d'un gicleur 206. L'utilisation du robinet T2 et du gicleur 206 est bien entendu optionnelle, néanmoins utile lorsqu'on désire gicler uniquement avec le liquide la surface sans passer à travers le dispositif de mélange 3.In Figure 2, we have shown seen from the side the control device 2 schematically. he it is a handle 201 provided with a trigger 202 which control by means of a spring switch or conventional piston of known type, the outlet of the liquid through the opening 203 of the control 2. The liquid supply is done through the line E1. Port 203 is usually connected to a T-shaped bypass device 204 Both other ends of the T are connected to a tap T1, respectively T2. The T1 tap allows to control the liquid supply of the mixing device 3. This mixing device 3 is supplied by air compressed through the air hose A4. The second tap T2 is connected to an elbow fitting 205 provided with a nozzle 206. The use of the T2 tap and the nozzle 206 is of course optional, however useful when you want to squirt only with the liquid the surface without passing through the mixing device 3.

Les éléments de la commande décrits jusqu'ici sont tout à fait conventionnels et connus de l'homme de l'art.The control elements described so far are all completely conventional and known to those skilled in the art.

En partant de cette commande conventionnelle, l'inventeur a apporté un certain nombre de modifications permettant de réaliser la présente invention.Starting from this conventional order, the inventor brought a number of modifications enabling this invention.

Dans un premier temps, on a disposé de part et d'autre de la poignée 201, deux distributeurs pneumatiques 207, 208. Le distributeur pneumatique 207 est muni d'une commande à levier 209, tandis que le distributeur pneumatique 208 est muni d'un interrupteur à bille qui sera actionné par la gâchette 202 au moyen d'un organe 210.At first, we arranged on both sides handle 201, two pneumatic distributors 207, 208. The pneumatic distributor 207 is provided with a lever control 209, while the distributor pneumatic 208 is fitted with a ball switch which will be actuated by trigger 202 by means of a member 210.

Les fonctions de ces distributeurs pneumatiques 207 et 208 seront expliquées par la suite en relation avec l'ensemble de la commande.The functions of these pneumatic distributors 207 and 208 will be explained later in relation to the entire command.

Le distributeur 207 aurait pu être une simple vanne comme il sera également expliqué par la suite.Distributor 207 could have been a simple valve as will also be explained later.

Sur la partie inférieure de la poignée 201, on a fixé une platine 211 sur laquelle sont fixés cinq raccords pneumatiques 212 à 215b. Ces raccords ont été représentés de manière schématique et leur but est de s'assurer que les différents tuyaux d'arrivée d'air comprimé utilisés pour commander les différents éléments à distance aboutissent à une partie fixe d'une poignée pour faciliter le travail et empêcher que ces différents tuyaux puissent s'emmêler.On the lower part of the handle 201, we fixed a plate 211 on which five fittings are fixed tires 212 to 215b. These fittings have been shown schematically and their purpose is to make sure that the different air supply pipes tablet used to control the different remote elements lead to a fixed part of a handle to facilitate work and prevent these different pipes may get tangled.

Sur un des côtés de la platine est fixé un régulateur de pression R2 présentant une entrée 216 et une sortie 217. Sur le raccord 212 abouti le tuyau A6. Sur l'autre extrémité du raccord 212 est montée un raccord en T ou en cinq branches (1 entrée, 4 sorties) 219. Le choix d'une pièce en T ou en cinq branches dépend du nombre de fonctions qu'on veut contrôler à distance comme il sera expliqué par la suite. La pièce de raccord 219 est reliée au moyen d'un tuyau non représenté à l'entrée 207a du distributeur 207, tandis que sa sortie 207b est reliée par un flexible à l'entrée 208a du distributeur 208. La sortie 208b est reliée par un flexible au raccord 214, lequel de son côté est relié à un tuyau A7 aboutissant à la commande de la vanne V1 du réservoir 6. Ainsi, lorsque l'interrupteur à bascule 209 laisse passer l'air comprimé à travers le distributeur 207, le distributeur 208 est alimenté et une pression sur la bille 208 à travers la gâchette 202 et l'organe 210 laisse passer l'air dans le tuyau A7 commmandant l'ouverture de la vanne d'alimentation V1 du réservoir 6, ce qui permet de commander l'arrivée du jet avec la matière de projection dans le dispositif 3 à travers le tuyau A4. En lâchant la gâchette 202 ou en basculant l'interrupteur 209, la vanne V1 se met en position de purge du réservoir.On one side of the plate is fixed a regulator pressure switch R2 having an inlet 216 and an outlet 217. On fitting 212 leads to pipe A6. On the other end of fitting 212 is mounted a T-fitting or in five branches (1 entry, 4 exits) 219. The choice of a T-piece or in five branches depends on the number of functions that we want to control remotely as it will be explained later. Connection piece 219 is connected by means of a pipe not shown at the inlet 207a of distributor 207, while its outlet 207b is connected by a hose to the inlet 208a of the distributor 208. The outlet 208b is connected by a hose to the connection 214, which in turn is connected to an A7 pipe leading to the control of the tank valve V1 6. So when the toggle switch 209 leaves pass the compressed air through the distributor 207, the distributor 208 is energized and pressure on the ball 208 through trigger 202 and member 210 allows air to pass through the controlling A7 pipe opening of the tank supply valve V1 6, which makes it possible to control the arrival of the jet with the projection material in device 3 through the pipe A4. By releasing trigger 202 or flipping switch 209, valve V1 goes to position drain the tank.

Si le robinet T1 est ouvert, le liquide passe également dans le dispositif 3 et le jet comprend l'air, le liquide et la matière à projeter. Si l'on désire arrêter la projection, il suffit de relâcher la poignée, ce qui empêche le passage d'air comprimé par la sortie 208b et la vanne V1 est fermée, ce qui arrête l'alimentation avec la matière à projeter, ainsi que le liquide. Si on veut utiliser la poignée pour uniquement un jet de liquide, il suffit de fermer le distributeur pneumatique 207 au moyen de la bascule 209 et appuyer sur la gâchette, ce qui permettra à travers soit le dispositif 3, soit le gicleur 206, la sortie du liquide. En lâchant la gâchette 202, on interrompt simultanément l'alimentation en liquide et en air, ainsi que la matière à projeter.If the valve T1 is open, the liquid also passes in device 3 and the jet includes air, liquid and the material to be sprayed. If we want stop the projection, just release the handle, preventing the passage of compressed air by outlet 208b and valve V1 is closed, which stops feeding with the material to be sprayed, as well as liquid. If you want to use the handle for only a jet of liquid, just close the dispenser pneumatic 207 by means of rocker 209 and press on the trigger, which will allow through either the device 3, i.e. the nozzle 206, the outlet of the liquid. By releasing trigger 202, we interrupt simultaneously supplying liquid and air, as well as the material to be projected.

La gâchette 202 remplace avantageusement sous la pression de l'eau ou d'un ressort la commande "homme mort" car ladite pression pousse la gâchette en position de repos interdisant les passages pneumatique et hydraulique vers la buse.The trigger 202 advantageously replaces under the water or spring pressure the "man" command dead "because said pressure pushes the trigger rest position preventing pneumatic passages and hydraulic to the nozzle.

Il est évident que le distributeur pneumatique 209 pourrait également être remplacé par un simple robinet que l'on ferme ou on l'ouvre. Néanmoins, un tel robinet ou vanne est relativement encombrant et si on se contente d'un petit robinet il est difficile à manier par l'utilisateur qui porte souvent des gants de travail épais. Un interrupteur à bascule est plus facile à manier et l'interrupteur 207 est de petite taille.It is obvious that the pneumatic distributor 209 could also be replaced by a simple tap that you close or open. Nevertheless, such a tap or valve is relatively bulky and if we happy with a small tap it is difficult to handle by the user who often wears gloves thick work. A toggle switch is more easy to handle and switch 207 is small cut.

Cette commande pneumatique aurait pu être également remplacée par une commande purement électrique, les distributeurs 207 et 208 étant un interrupteur électrique conventionnel suivi d'un contacteur qui serait également actionné par la gâchette 202. Le désavantage de cette solution est qu'il n'est pas toujours aisé d'amener l'électricité à l'endroit de travail et, d'autre part, la présence du liquide demande la mise en place de mesures de sécurité importantes pour éviter les accidents.This pneumatic control could also have been replaced by a purely electric control, the distributors 207 and 208 being a switch conventional electric followed by a contactor which would also be triggered by trigger 202. The disadvantage of this solution is that it is not always easy to bring electricity to the place of work and, on the other hand, the presence of liquid requests the implementation of security measures important to avoid accidents.

La deuxième amélioration apportée par la présente invention est le contrôle et la commande à distance de la pression du circuit pneumatique. Ainsi, à partir de la deuxième branche de la pièce 219 au moyen d'un flexible, l'air est conduit dans l'entrée 216 du régulateur de pression R2 muni d'un affichage 218 et il sort par la sortie 217 pour être par la suite conduit au moyen d'un flexible sur le raccord 213, lequel de son côté est branché sur le tuyau d'air A9 commandant le dispositif de régulation R1. Le régulateur R2 est un élément existant dans le commerce et ne représente aucune caractéristique spécifique à cette application. Ce dispositif permet donc, d'une part, de contrôler la pression du circuit pneumatique et, d'autre part, de la régler en fonction du travail et du résultat obtenu par l'utilisateur. Il s'agit d'une commande interactive facilitant le travail de l'utilisateur, lequel jusqu'à maintenant doit soit être assisté d'une deuxième personne qui règle la pression en fonction des indications directement sur le dispositif R1, soit se déplacer lui-même pour effectuer ce réglage et recommencer.The second improvement brought by this invention is the remote control and command of the pressure of the pneumatic circuit. So from the second branch of room 219 by means of a flexible, the air is led into entry 216 of the R2 pressure regulator with display 218 and it exit via exit 217 to be subsequently driven by means of a hose on connection 213, which of its side is connected to the air hose A9 commanding the regulation device R1. The R2 regulator is a element existing in trade and does not represent no specific features for this application. This device therefore makes it possible, on the one hand, to control the pressure of the pneumatic circuit and, on the other hand, of the pay according to the work and the result obtained by the user. It is an interactive command facilitating the work of the user, who up to now must either be assisted by a second person who regulates the pressure according to indications directly on the R1 device, i.e. move itself to make this adjustment and restart.

Enfin, une dernière amélioration qui pourrait être introduite est le réglage du débit de la matière à projeter. Si ce pilotage à distance de la vanne V2 est désiré, dans ce cas la pièce 219 n'est pas un raccord en forme de T, mais un raccord en cinq branches, la quatrième et la cinquième branches étant reliées à un dispositif non représenté permettant de commander le débit de la vanne V2. Les sorties de ce dispositif qui pourraient être fixées comme le régulateur R2 de l'autre côté de la platine 211 sont reliées aux raccords 215a à 215b de la platine 211, lequel est de son côté relié à travers la double ligne A8 à la commande de la vanne V2. Le dispositif de commande de la vanne V2 peut avantageusement comprendre un vérin à double effet actionné par deux distributeurs à billes comme le distributeur 208. Ainsi, en fonction de la modification du débit souhaitée, on actionne l'un ou l'autre de ces distributeurs pour faire déplacer le piston ouvrant ou fermant la vanne V2. Au lieu de deux distributeurs pneumatiques, on pourrait utiliser deux robinets ou vannes.Finally, a final improvement which could be introduced is the adjustment of the flow rate of the material to project. If this remote control of valve V2 is desired, in this case part 219 is not a fitting T-shaped, but a five-branch fitting, the fourth and fifth branches being connected to a device not shown for controlling the flow rate of valve V2. The outputs of this device which could be set as the R2 regulator of the other side of plate 211 are connected to connections 215a to 215b of plate 211, which is its side connected through the double line A8 to the valve V2 control. The control device the valve V2 can advantageously comprise a cylinder with double effect operated by two ball distributors like the distributor 208. So depending on the modification of the desired flow, one or the other of these distributors to move the piston opening or closing the valve V2. Instead of two pneumatic distributors we could use two taps or valves.

Dans le but de ne pas charger les figures, les flexibles reliant les raccords 212 à 215b aux différents éléments ne sont pas représentés. De même, sur la figure 2, on a uniquement représenté la platine 211 sans les raccords.In order not to load the figures, the hoses connecting fittings 212 to 215b to different elements are not shown. Likewise, in Figure 2, only the plate is shown 211 without fittings.

Il est évident qu'une modification de la poignée 201 de l'origine permettra d'intégrer à l'intérieur plusieurs de ces éléments rendant la commande plus ergonomique.It is obvious that a modification of the handle 201 of the origin will allow to integrate inside several of these elements making the control more ergonomic.
