En general, tal proyección de líquido limpiador consiste en un chorro de reducido diámetro, con un caudal y presión adecuados a la envergadura del parabrisas, o en una pulverización de líquido limpiador. Los medios de proyección de líquido limpiador basados en la proyección de un chorro sobre un punto del parabrisas tienen como inconveniente que la distribución de líquido limpiador sobre la superficie del parabrisas es realizada por la acción de las raquetas al cabo de varios ciclos. Además, se requiere un caudal de líquido limpiador sensiblemente elevado. Por otro lado, los medios de proyección de líquido limpiador basados en la pulverización de éste solucionan los inconvenientes derivados de un elevado consumo, ya que en cada operación de limpieza del parabrisas el caudal de líquido limpiador utilizado es mucho menor del que precisan los medios de proyección basados en la proyección de un chorro, pero presentan como inconveniente, bajo ciertas condiciones, el producir una elevada dispersión del líquido limpiador, lo que dificulta la operación de limpieza del parabrisas.Multiple embodiments of jets for windshield washers of motor vehicles are known which, essentially, consist of a spout body fixed to the body of the vehicle, frequently fixed to the engine hood, and by means of projection of cleaning liquid, capable of being oriented. - two to obtain a point or zone of projection of liquid on the suitable windshield to facilitate the action of the cleaning rackets. In general, such a projection of cleaning fluid consists of a jet of small diameter, with a flow and pressure suitable to the wingspan of the windshield, or a spray of cleaning fluid. The projection means of cleaning fluid based on the projection of a jet on a point of the windshield have the disadvantage that the distribution of cleaning liquid on the surface of the windshield is carried out by the action of the rackets after several cycles. In addition, a substantially high flow of cleaning fluid is required. On the other hand, the projection means of cleaning liquid based on the spraying of this one solve the inconveniences derived from a high consumption, since in each windshield cleaning operation the flow of cleaning liquid used is much lower than that required by the means of projection based on the projection of a jet, but present as inconvenient, under certain conditions, producing a high dispersion of the cleaning fluid, which makes the windshield cleaning operation difficult.

El dispositivo según la invención proyecta en forma de abanico el líquido limpiador sobre el parabrisas del vehículo, consiguiendo de este modo por un lado producir una distribución de líquido limpia- dor sobre la superficie del parabrisas facilitando la acción de las raquetas, ya que el líquido limpiador alcanza al parabrisas en una franja que sin solución de continuidad se extiende en una amplitud dada por la proyección en abanico, y por otro lado que el consumo de líquido limpiador, a igualdad de resultados en cuanto a nivel de limpieza del parabrisas, no alcance los valores de consumo que requieren los sistemas de proyección de chorro.The characteristics described above of the projection device object of the invention, provide an innovative solution to the aforementioned drawbacks presented by the known embodiments of projection devices, based in the projection of a jet of cleaning fluid or in the spray of cleaning liquid on the windshield of the vehicle.

Además, el orificio 30 está provisto en su fondo de una ranura 34 adaptada para recibir el resalte 13 del primer cuerpo de proyección 1. En la Fig. 9 aparece representado en sección el acoplamiento de la unidad de proyección 3 al cuerpo de surtidor 4 y en ella se aprecia que el acoplamiento configura una cámara de entrada 33 en la que desemboca el orificio 32 de la boquilla 6, y la conducción de líquido limpiador 23 configurada por el acoplamiento de los cuerpos de proyección 1 y 2. Además, la ranura 34 en el fondo del orificio 30 del cuerpo de surtidor 4 recibe al resalte 13 del primer cuerpo de proyección 1 de la unidad de proyección 3.In Figs. 7 and 8 it can be seen that the dispenser body 4 has a general prismatic shape and is provided with a transverse hole 30, sized to receive the projection unit 3 shown in Fig. 5, and an outlet opening 31 adapted for allow passage through the fan projection of cleaning liquid from the projection unit 3. The hole 30 establishes hydraulic communication with the conduction of cleaning liquid to the projection device through a hole 32 of the nozzle 6. In addition, the hole 30 is provided at its bottom with a groove 34 adapted to receive the projection 13 of the first projection body 1. In Fig. 9 the coupling of the projection unit 3 to the dispenser body 4 is shown in section and it is appreciated that the coupling configures an inlet chamber 33 into which the hole 32 of the nozzle 6, and the cleaning liquid line 23 configured by the coupling of the projection bodies 1 and 2. In addition, the groove 34 at the bottom of the hole 30 of the dispenser body 4 receives the projection 13 of the first projection body 1 of the projection unit 3 .
El funcionamiento del dispositivo de proyección de líquido limpiador para surtidores de lavaparabrisas de vehículos automóviles objeto de la invención se describe seguidamente. La unidad de proyección 3 puede ser girada alrededor de su eje longitudinal en ambos sentidos, por deslizamiento del resalte 13 del primer cuerpo de proyección 1 a través de la ranura 34 del fondo del orificio 30 del cuerpo de surtidor 4, empleando para ello, por ejemplo, un destornillador aplicado a la ranura 6 prevista al efecto en el primer cuerpo de proyección 1. El giro de la unidad de proyección 3 permite adaptar la posición de la boca de salida 29 de líquido limpiador a la posición y dimensiones del parabrisas del vehículo y se realiza entre dos posiciones, fijadas precisamente por los extremos de la ranura 34, con el fin de evitar que un giro excesivo de la unidad de proyección 3 llegase a provocar la obturación de la boca de salida 29 por el propio cuerpo de surtidor 4.The operation of the projection device for cleaning fluid for windshield washer dispensers of motor vehicles object of the invention is described below. The projection unit 3 can be rotated about its longitudinal axis in both directions, by sliding the projection 13 of the first projection body 1 through the groove 34 at the bottom of the hole 30 of the dispenser body 4, using For example, a screwdriver applied to the groove 6 provided for this purpose in the first projection body 1. The rotation of the projection unit 3 makes it possible to adapt the position of the outlet mouth 29 of cleaning fluid to the position and dimensions of the windshield of the vehicle and is carried out between two positions, fixed precisely by the ends of the groove 34, in order to prevent excessive rotation of the projection unit 3 from causing the outlet 29 to be sealed by the dispenser body 4 itself .
Durante la operación de limpieza del parabrisas, el líquido limpiador alcanza la cámara de entrada 33, configurada por el acoplamiento de la unidad de proyección 3 con el cuerpo de surtidor 4, a través del orificio 32 de la boquilla 6; seguidamente, los planos inclinados 11 y 18 del primer y segundo cuerpos de proyección 1 y 2, respectivamente, determinan una embocadura de direccionamiento del líquido limpiador hacia el conducto 23, formado por el acoplamiento de los cuerpos de proyección 1 y 2. La acción del regruesamiento central 22 determina la formación de dos corrientes independientes de líquido limpiador, que atraviesan las porciones primera 26, segunda 27 y tercera 28 de respectivos pasos 24, para converger fi- nalmente ambas corrientes en la cámara de salida 25, donde se forma una única corriente que es proyectada al exterior en abanico por la boca de salida 29 de la unidad de proyección 3, atravesando la abertura 31 del cuerpo de surtidor 4. During the windshield cleaning operation, the cleaning fluid reaches the inlet chamber 33, configured by coupling the projection unit 3 with the dispenser body 4, through the hole 32 of the nozzle 6; then, the inclined planes 11 and 18 of the first and second projection bodies 1 and 2, respectively, determine a directional mouth of the cleaning liquid towards the duct 23, formed by the coupling of the projection bodies 1 and 2. The action of the central thickening 22 determines the formation of two independent streams of cleaning liquid, which pass through the first 26, second 27 and third 28 portions of respective steps 24, to finally converge both streams in the outlet chamber 25, where a single current that is projected to the outside in a fan through the outlet 29 of the projection unit 3, passing through the opening 31 of the dispenser body 4.
