Abstract

The invention relates to a dispensing device comprising a hollow body that is divided into a depressurisation chamber and a dispensing chamber by means for converting the pressure variations of the pressurisation chamber into variations in the volume of the dispensing chamber, said conversion means taking the form of an elastomer that has a cavity which forms the dispensing chamber itself. The depressurisation chamber is connected to an inlet cock that has a narrowing and terminates in an inlet valve, and the dispensing chamber is connected to an intermediate section of a secondary circuit, which intermediate section terminates at each end in corresponding check valves that extend the secondary circuit into an impulse section and an aspiration section, the aspiration section being connected to a store of the product to be dispensed. The closure of the inlet valve reduces the volume of the dispensing chamber by compressing the elastomer, thereby expelling the fluid to be dispensed.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Se conocen numerosos dispositivos dispensadores del tipo que nos ocupa. Así, el documento ES 2159392T3 describe un dispositivo dosificador para añadir un esterilizante a una red de suministro de agua a fin de proporcionar agua esterilizada a los consumidores. El dispositivo comprende un depósito de esterilizante y un sistema de control que a partir de una medida de caudal transmite las órdenes oportunas para mantener una concentración de esterilizante prefijada, operándose mediante aire comprimido. El documento ES 1049300U describe un dosificador de desinfectantes para aparatos sanitarios que utiliza una bomba accionada por un motor a pilas. Como en el caso anterior, se precisa una fuente de energía externa. Numerous dispensing devices of the type in question are known. Thus, document ES 2159392T3 describes a dosing device for adding a sterilant to a water supply network in order to provide sterilized water to consumers. The device comprises a sterilant tank and a control system that, based on a flow measurement transmits the appropriate orders to maintain a pre-fixed sterilizer concentration, operating with compressed air. The document ES 1049300U describes a disinfectant dispenser for sanitary appliances that uses a pump driven by a battery-operated motor. As in the previous case, an external energy source is required.
Son conocidos asimismo, otros dispositivos que no precisan energía externa. Así el documento US 5,692,250 se refiere a la dispensación automática de un líquido desinfectante en aparatos sanitarios de vacío sin cisterna, del tipo de los utilizados en aviación. La energía para mover la bomba dispensadora proviene de las variaciones de presión del circuito de agua potable de a bordo, utilizado para la limpieza de la taza del sanitario. Esta bomba dispensadora está conectada después de la válvula de apertura del circuito y vierte a la taza del sanitario, con lo que la presión varía entre un valor cero y la plena presión estática del circuito de agua principal, lo que constituye un salto excesivamente importante y brusco de la presión. Esto unido a la constitución mecánica de la bomba, un pistón flotante cargado con un resorte, conduce a una operación ruidosa y a la aparición de constantes averías. Other devices that do not require external energy are also known. Thus, US Pat. No. 5,692,250 refers to the automatic dispensing of a liquid disinfectant in sanitary vacuum devices without tanks, of the type used in aviation. The energy to move the dispensing pump comes from the pressure variations of the on-board potable water circuit, used to clean the toilet bowl. This dispensing pump is connected after the opening valve of the circuit and pours into the sanitary cup, whereby the pressure varies between a zero value and the full static pressure of the main water circuit, which constitutes an excessively important jump and abrupt pressure. This coupled with the mechanical constitution of the pump, a floating piston loaded with a spring, leads to a noisy operation and the appearance of constant breakdowns.
El documento ES 2377092B1 describe un dispositivo muy próximo al anterior, pero adaptado a los sanitarios habituales con cisterna. En este caso, las cámaras impulsoras de la bomba presentan ambas una entrada y una salida, lo que complica aún más los problemas mecánicos y de estanqueidad de los pistones flotantes que constituyen el corazón del sistema. El dispositivo se ubica, como en el caso anterior, detrás de la válvula de entrada y descarga, lo que da lugar a varios problemas: The document ES 2377092B1 describes a device very close to the previous one, but adapted to the usual toilets with cistern. In this case, the pump chambers have both an inlet and an outlet, which further complicates the mechanical and sealing problems of the floating pistons that make up the heart of the system. The device is located, as in the previous case, behind of the inlet and discharge valve, which gives rise to several problems:
• El salto de presión, entre la presión estática del circuito principal y cero es demasiado alto y, sobre todo, brusco.  • The pressure jump, between the static pressure of the main circuit and zero is too high and, above all, abrupt.
• La dispensación del producto se produce en el momento de la apertura de la válvula de descarga, por lo que la actuación del desinfectante es muy corta y transitoria, siendo barrido por la descarga posterior del agua de limpieza proveniente del circuito principal. Esto se agrava en el caso de sanitarios sin cisterna.  • The dispensing of the product occurs at the moment of the opening of the discharge valve, so that the disinfectant's action is very short and transient, being swept by the subsequent discharge of the cleaning water from the main circuit. This is worse in the case of toilets without cistern.
Se conocen también dispositivos que aspiran directamente, desde un depósito, el fluido a dispensar, tal como el descrito en el documento US 2009/0100579 Al, que utiliza un Venturi . Este dispositivo opera de forma continua mientras hay flujo en el circuito principal, por lo que el consumo del fluido a dispensar es muy elevado, con dificultades de regulación. Devices are also known that directly aspirate, from a reservoir, the fluid to be dispensed, such as that described in US 2009/0100579 Al, which uses a Venturi. This device operates continuously while there is flow in the main circuit, so the consumption of the fluid to be dispensed is very high, with regulation difficulties.
En consecuencia, es un objetivo de la presente invención el disponer de un dispositivo dispensador que actúe al final de la descarga, al cortar el flujo en el circuito principal. Accordingly, it is an object of the present invention to provide a dispensing device that acts at the end of the discharge, by cutting off the flow in the main circuit.
Es otro objetivo de la presente invención el disponer de un dispositivo dispensador de accionamiento suave . Y finalmente, es otro objetivo de la presente invención el disponer de un dispositivo dispensador más sencillo y económico, sin problemas de estanqueidad . It is another object of the present invention to provide a soft drive dispensing device. And finally, it is another objective of the present invention to have a simpler and more economical dispensing device, without sealing problems.
DESCRIPCIÓN DE LA INVENCIÓN Para alcanzar los objetivos propuestos se ha concebido un dispositivo dispensador dispuesto antes de la válvula de entrada del circuito principal. De esta forma, el dispositivo dispensador de la invención siempre está presurizado, generándose las variaciones de presión necesarias a su operación mediante una DESCRIPTION OF THE INVENTION To achieve the proposed objectives, a dispensing device disposed before the main circuit inlet valve has been conceived. In this way, the dispensing device of the invention is always pressurized, generating the pressure variations necessary for its operation by means of a
restricción dispuesta en el grifo de entrada que conecta el circuito principal a la válvula de entrada. En el contexto de este documento se entenderá por restriction arranged in the inlet tap that connects the main circuit to the inlet valve. In the context of this document, it shall be understood
"restricción" un tramo de circuito que presenta un diámetro dimensionado para provocar una aceleración del fluido principal cuando la válvula de entrada está abierta. Este diámetro será habitualmente menor que el del resto del circuito principal, y su dimensionamiento estará definido, además de por las condiciones del propio dispositivo, por la pérdida de carga de la válvula de entrada. El fundamento de la invención es sustituir el salto de presión todo o nada de la técnica anterior por un salto de presión menor en valor absoluto y de transición suave, produciéndose la dispensación al final de la descarga, cuando el circuito principal, sin flujo, se encuentra a su máxima presión. "Restriction" a circuit section having a diameter dimensioned to cause an acceleration of the main fluid when the inlet valve is open. This diameter will usually be less than that of the rest of the main circuit, and its sizing will be defined, in addition to the conditions of the device itself, by the loss of load of the inlet valve. The basis of the invention is to replace the pressure jump all or nothing of the prior art by a pressure jump lower in absolute value and smooth transition, producing the dispensation at the end of the discharge, when the main circuit, without flow, is Find your maximum pressure.
El teorema de Bernoulli que define el Bernoulli's theorem that defines the
comportamiento de fluidos en una conducción establece que; (p/dg) + (v2/2g) =k . Fluid behavior in a driving states that; (p / dg) + (v 2 / 2g) = k.
Siendo p la presión, v la velocidad del fluido, d la densidad del fluido, g la aceleración de la  Where p is the pressure, v the velocity of the fluid, d the density of the fluid, g the acceleration of the

De esta forma, si introducimos una restricción en el grifo de entrada del circuito principal, antes de la válvula de entrada, el dispositivo estará siempre presurizado, bien con la presión estática cuando no haya flujo, bien con una presión dependiente de la velocidad de paso del fluido cuando la válvula de entrada del circuito principal esté abierta. La presencia de una restricción permite disponer de un salto de presión suficiente para accionar el dispositivo, pero no In this way, if we introduce a restriction in the inlet tap of the main circuit, before the inlet valve, the device will always be pressurized, either with the static pressure when there is no flow, or with a pressure dependent on the speed of fluid flow when the inlet valve of the main circuit is open. The presence of a restriction allows a sufficient pressure jump to operate the device, but not

La parte dispensadora del dispositivo, es similar a la descrita en la primera variante (Figura 1) del documento US 5,692,250 y comprende un cuerpo hueco, venta osamente cilindrico, dividido en una cámara de presurización y una cámara dispensadora por medios de conversión de las variaciones de presión de la cámara de presurización en variaciones de volumen de la cámara dispensadora, conectándose la cámara de presurización al grifo de entrada en la zona de la restricción y la cámara dispensadora a un circuito secundario que incluye el depósito de fluido a dispensar y un par de válvulas antiretorno que aseguren su circulación según una disposición habitual en hidráulica. The dispensing part of the device is similar to that described in the first variant (Figure 1) of US Pat. No. 5,692,250 and comprises a hollow body, sold cylindrically, divided into a pressurization chamber and a dispensing chamber by means of conversion of the variations of pressure of the pressurization chamber in volume variations of the dispensing chamber, the pressurization chamber being connected to the inlet tap in the restriction zone and the dispensing chamber to a secondary circuit that includes the reservoir of fluid to be dispensed and a pair of anti-return valves that ensure their circulation according to a usual arrangement in hydraulics.
Venta osamente los medios de conversión de las variaciones de presión de la cámara de presurización en variaciones de volumen de la cámara dispensadora estarán constituidos por una pieza elastómera de forma Selling the means for converting the pressure variations of the pressurization chamber into volume variations of the dispensing chamber will be constituted by an elastomeric piece of shape.
cilindrica que presenta una cavidad que constituye la cámara dispensadora en si. Una tal solución es incapaz de soportar el salto de presión todo o nada del circuito principal pero, sorprendentemente, trabaja con eficacia y suavidad cuando permanece constantemente presurizada, con variaciones de presión controladas. La explicación está no solo en los valores absolutos del salto de presión, sino en que al producirse éstos por variaciones de caudal, la propia inercia del fluido establece cambios de presión progresivos. Aunque la variante anterior, en elastomero, de los medios de conversión de variaciones de presión en variaciones de volumen presenta una sinergia evidente con la utilización de una restricción, pueden utilizarse medios convencionales como pistones flotantes, fuelles o similares en aquellos casos en que las elevadas cylindrical that presents a cavity that constitutes the dispensing chamber itself. Such a solution is unable to withstand the pressure jump all or nothing of the main circuit but, surprisingly, works effectively and smoothly when it remains constantly pressurized, with controlled pressure variations. The explanation is not only in the absolute values of the pressure jump, but in that when these are produced by flow variations, the fluid's own inertia establishes progressive pressure changes. Although the previous variant, in the elastomer, of the means of converting pressure variations into volume variations presents an obvious synergy with the use of a restriction, conventional means such as floating pistons, bellows or the like can be used in those cases where the high
presiones o la agresividad química del fluido a pressures or the chemical aggressiveness of the fluid to
dispensar desaconsejen la utilización de un elastomero. Las ventajas del dispositivo dispensador de la invención son definitivas, así: dispense with the use of an elastomer. The advantages of the dispensing device of the invention are definitive, as follows:
• La dispensación del producto tiene lugar al cerrar la válvula de entrada, en lugar de en su apertura como ocurre en la técnica anterior. Esto permite que, por ejemplo en sanitarios sin cisterna, el producto permanezca en la taza del mismo.  • The dispensing of the product takes place when closing the inlet valve, instead of in its opening as in the prior art. This allows that, for example in toilets without cistern, the product remains in the toilet bowl.
• Presenta un funcionamiento suave y silencioso • Presents smooth and silent operation
• En versión elastomero presenta una gran sencillez mecánica, bajo precio y larga duración. BREVE DESCRIPCIÓN DE LAS FIGURAS • In the elastomer version it has great mechanical simplicity, low price and long duration. BRIEF DESCRIPTION OF THE FIGURES

The inlet tap (5) starts at a connection to the main circuit (12) and ends at an inlet valve (13).
Haciendo referencia ahora a las figuras 3 y 4, describiremos las particularidades de aplicación del dispositivo dispensador de la invención a un sanitario con cisterna (15), en el que, particularizando el caso general, la válvula de entrada (13) se acciona mediante un flotador (14) y un tirador (16) acciona una válvula de fondo (17) para provocar la descarga de la cisterna (15) de forma convencional. El depósito (11) puede ir incorporado en la cisterna (15) o ser exterior a la misma. En este último caso, un solo depósito (11) puede alimentar una pluralidad de sanitarios, con o sin cisterna . Referring now to Figures 3 and 4, we will describe the particularities of application of the dispensing device of the invention to a sanitary with cistern (15), in which, particularizing the general case, the inlet valve (13) is actuated by a float (14) and a handle (16) operates a bottom valve (17) to cause the discharge of the cistern (15) in a conventional manner.
