El sistema comprende un órgano de control que determina en todo momento cual es el estado de cada cámara, el color que está llenando la cámara y el estado de cada válvula . Cuando deba retornarse una cámara a un estado transparente habrá que hacer siempre un drenaje previo del conducto inferior y su "lavado" mediante la impulsión del fluido transparente, más ligero, a la cavidad del último color que ha circulado por ella, de modo que alcanzada la cavidad color y líquido transparente, por flotación se producirá la incorporación del fluido transparente al depósito correspondiente y por su mayor densidad el descenso del líquido coloreado, que quedará confinado en su correspondiente cavidad.

• Al menos una bomba (10,11) para desplazamiento de los fluidos en cada uno de los conductos superior e inferior;  • At least one pump (10,11) for moving the fluids in each of the upper and lower conduits;
• Un conjunto de válvulas (8a,8b,9a,9b); al menos habrá una válvula que conectará el conducto inferior (3) con las conducciones con cada uno de las cavidades (6, 7) de los fluidos coloreados y con las cámaras a colorear; según la realización representada, las válvulas (8a, 8b, 9a, 9b) son válvulas de tres vías, con una vía de comunicación entre las cámaras (1,2) y las cavidades (6,7), y el conducto inferior; y otras dos vías que comunican el paso del conducto inferior a uno y otro lado de la correspondiente válvula; de este modo, en cada válvula puede cerrarse el paso a cada de las cavidades/cámaras y permitir el paso a lo largo del conducto inferior, conectar el conducto inferior con una cámara y/o cavidad o quedar totalmente cerradas en sus tres bocas o dos de ellas.  • A set of valves (8a, 8b, 9a, 9b); at least there will be a valve that will connect the lower conduit (3) with the conduits with each of the cavities (6, 7) of the colored fluids and with the chambers to be colored; according to the represented embodiment, the valves (8a, 8b, 9a, 9b) are three-way valves, with a communication path between the chambers (1,2) and the cavities (6,7), and the lower conduit; and two other ways that communicate the passage of the lower conduit on either side of the corresponding valve; in this way, each valve can close the passage to each of the cavities / chambers and allow the passage along the lower conduit, connect the lower conduit with a chamber and / or cavity or be completely closed in its three mouths or two of them.
Las cámaras estarán siempre llenas con un fluido, bien un fluido transparente, bien un fluido coloreado; dichos fluidos tienen distinta densidad, de modo que uno, normalmente el transparente, flota sobre el otro, normalmente los coloreados. The cameras will always be filled with a fluid, either a transparent fluid, or a colored fluid; said fluids have different density, so that one, normally the transparent, floats on the other, normally the colored ones.
El procedimiento para el cambio de color de la cámara (1,2) comprende, según el estado actual, las siguientes etapas; The procedure for changing the color of the camera (1,2) comprises, according to the current state, the following steps;
• Limpieza del conducto inferior, retornando el fluido coloreado a la cavidad correspondiente por la acción de una bomba (11); en esta fase las válvulas de las cámaras y de las cavidades que no correspondan al color que se está limpiando quedarán cerradas, y se producirá un flujo desde el depósito hasta la cavidad (6,7) correspondiente al color que se está retirando; debido a la flotación del fluido transparente respecto al fluido coloreado, una vez alcanzada la cavidad o el conducto vinculado a ella, se producirá un burbujeo hacia arriba, de modo que se estabilizará quedando el fluido transparente arriba, en el depósito, y el fluido coloreado confinado en la cavidad correspondiente; la cantidad de fluido coloreado nunca debe ser mayor que la capacidad de la correspondiente cavidad; • Cleaning the lower duct, returning the colored fluid to the corresponding cavity by the action of a pump (11); in this phase the valves of the chambers and of the cavities that do not correspond to the color being cleaned will be closed, and a flow will be produced from the reservoir to the cavity (6,7) corresponding to the color that is being removed; due to the floating of the transparent fluid respect to the colored fluid, once the cavity or the conduit connected to it is reached, an upward bubbling will take place, so that it will stabilize leaving the transparent fluid above, in the reservoir, and the colored fluid confined in the corresponding cavity; the amount of colored fluid should never be greater than the capacity of the corresponding cavity;
• Apertura de las válvulas que conectan la cámara a colorear y la cavidad provista del color correspondiente con el conducto inferior; • Opening of the valves that connect the chamber to be colored and the cavity provided with the corresponding color with the lower duct;
• Aspiración desde el conducto superior por medio de una bomba (10) del fluido transparente para el llenado de la cámara correspondiente con un fluido coloreado, o bien aspiración desde el conducto inferior para el vaciado del fluido coloreado; • Aspiration from the upper duct by means of a pump (10) of the transparent fluid for filling the corresponding chamber with a colored fluid, or suction from the lower duct for emptying the colored fluid;
• Cierre de la válvula que conecta la cámara a colorear; las otras permanecen cerradas, a excepción de la válvula que conecta la cámara con el fluido coloreado y el conducto inferior; apertura de las válvulas que permiten el paso por el conducto inferior, en tanto que sea necesario;  • Closing of the valve that connects the camera to be colored; the others remain closed, with the exception of the valve that connects the chamber with the colored fluid and the lower conduit; opening of the valves that allow the passage through the lower conduit, as long as it is necessary;
• Limpieza por barrido mediante la impulsión del fluido por medio de la bomba (11), que lo toma del depósito y lo incorpora en la cavidad del color correspondiente.  • Cleaning by sweeping by means of the fluid supply by means of the pump (11), which takes it from the tank and incorporates it in the cavity of the corresponding color.
Las cámaras están formadas por la unión de dos o más palcas de vidrio que dejan entre cada par, una cámara estanca, susceptible de ser inundada a voluntad con un fluido coloreado con el color elegido, o con el fluido transparente que se usa para limpiar el circuito y que no se mezclen los colores. The chambers are formed by the union of two or more glass plates that leave between each pair, a sealed chamber, capable of being flooded at will with a colored fluid with the chosen color, or with the transparent fluid used to clean the circuit and that the colors do not mix.
Aún cuando se representa, a título de ejemplo, la invención para dos colores y dos cámaras, obviamente el número de unos y otras no queda limitado por la exposición dada. Una determinada cámara puede estar coloreada con uno u otro color, y un color puede llenar más de una cámara . Even when the invention for two colors and two cameras is represented, by way of example, obviously the number of some and others is not limited by the given exposure. A certain camera can be colored with one or another color, and one color can fill more than one camera.
Las bombas y válvulas serán normalmente de alimentación eléctrica, pero podrían ser hidráulicas o mediante otro accionamiento. The pumps and valves will normally be electrical, but could be hydraulic or by another drive.
Está previsto que al menos uno de los circuitos esté provisto de un intercambiador de calor para el enfriamiento de los fluidos y de los circuitos por los que circulan, tanto para un correcto funcionamiento como para mantener en el interior una temperatura adecuada. It is planned that at least one of the circuits be provided with a heat exchanger for the cooling of fluids and circuits by those who circulate, both for proper operation and to maintain an adequate temperature inside.
Del mismo modo está previsto que el circuito incluya un medio calefactor, por ejemplo un conjunto de resistencias, para el calentamiento del fluido, evitando congelaciones, y manteniendo un correcto funcionamiento del mismo y una temperatura en el interior del recinto en el que se sitúan. In the same way it is foreseen that the circuit includes a heating means, for example a set of resistances, for heating the fluid, avoiding freezing, and maintaining correct operation thereof and a temperature inside the room in which they are located.
Conforme a una opción adicional, alguna de las cámaras podrá estar provista de un dispositivo de iluminación tangencial o perimetral, por ejemplo mediante un conjunto de LED dispuestos en el marco portador de dichas cámaras. According to an additional option, some of the cameras may be provided with a tangential or perimeter lighting device, for example by means of a set of LEDs arranged in the frame carrying said cameras.
Según la invención, se incluye también un órgano de control que automatiza las operaciones de llenado de las cámaras desde arriba o desde abajo con uno u otro color, accionamiento de las bombas y drenaje de los circuitos para evitar las mezclas de colores. Bastará indicar que color se desea obtener en una determinada cámara (o en un conjunto de cámaras) para que el sistema realice automáticamente todas las operaciones necesarias desde el estado actual hasta que sea llenada con el color deseado. According to the invention, there is also included a control organ that automates the operations of filling the chambers from above or from below with one or another color, actuating the pumps and draining the circuits to avoid mixing colors. It will be enough to indicate what color you want to obtain in a certain camera (or in a set of cameras) so that the system automatically performs all the necessary operations from the current state until it is filled with the desired color.
