De modo esencial, la válvula con conjunto de bomba objeto de la presente invención está constituida por tres piezas de forma general cilíndrica de dos o más diámetros encajados entre sí, poseyendo la primera de ellas una estructura de dos cilindros sucesivos, quedando fijada entre el tapón del recipiente portador de la substancia a dosificar y el borde del gollete del propio recipiente, mientras que la segunda pieza está destinada a actuar como émbolo principal, deslizando por su parte superior en el interior de la primera pieza y presentando un extremo terminal de menor diámetro guiado en la parte de menor diámetro de la primera pieza y presentando en su zona intermedia un diámetro asimismo intermedio con las lumbreras principales de llenado y de salida del producto, y la tercera pieza está formada por un vástago hueco solidario del asa-boquilla de salida y que presenta asimismo una estructura cilíndrica con dos diámetros distintos sucesivos deslizando el diámetro mayor, dotado de nervios periféricos de tope, en el interior de la parte de émbolo de la segunda pieza, mientras que el extremo asimismo cilíndrico de dicha tercera pieza es susceptible de encajar en el extremo terminal de menor diámetro de la segunda pieza, presentando además un resalte en forma de anillo intermedio susceptible de llegar a establecer tope en una zona conjugada de la segunda pieza. Dicha tercera pieza presenta un tabique transversal que separa el recinto hueco de la parte superior, en comunicación con la boquilla de salida, con respecto al extremo terminal susceptible de encajar en la parte más estrecha de la segunda pieza. Dicha tercera pieza presenta por encima del mencionado tabique intermedio unas lumbreras de comunicación de una cámara intermedia receptora del producto a dosificar, determinada principalmente por las paredes internas de la primera pieza tubular, con la parte superior del vástago hueco que comunica con la boquilla de salida.Essentially, the valve with set of pump object of the present invention is constituted by three general cylindrical pieces of two or more diameters fitted each other, the first one having a structure of two successive cylinders, being fixed between the container cap carrier of the substance to be dosed and the edge of the neck of the own container, while the second piece is intended for act as the main plunger, sliding along its top in the inside the first piece and presenting a terminal end of smaller diameter guided in the part of smaller diameter of the first piece and presenting in its intermediate zone a diameter likewise intermediate with the main filling and outlet ports of the product, and the third piece is formed by a hollow stem solidarity of the handle-outlet nozzle and presenting also a cylindrical structure with two different diameters successive sliding the larger diameter, equipped with nerves stop peripherals, inside the piston part of the second piece, while the cylindrical end of said third piece is likely to fit into the terminal end of smaller diameter of the second piece, also presenting a protrusion in intermediate ring shape capable of reaching a stop in a conjugate area of the second piece. That third piece It has a transverse partition that separates the hollow enclosure from the upper part, in communication with the outlet nozzle, with with respect to the terminal end likely to fit in the most part Narrow of the second piece. Said third piece presents by above the mentioned intermediate partition some louvres of communication of an intermediate chamber receiving the product to dose, determined primarily by the internal walls of the first tubular piece, with the upper part of the hollow stem that communicates with the outlet nozzle.

Las posiciones de tope axial superior e inferior de la segunda pieza, portadora del cuerpo del émbolo principal, se establecen respectivamente por un resalte interno del tapón de cierre del recipiente portador de producto a dosificar y un resorte interno de la primera pieza del dispositivo, que determina el tope de desplazamiento inferior al incidir el cuerpo del émbolo sobre el mismo.The upper and lower axial stop positions of the second piece, carrier of the main piston body, is set respectively by an internal shoulder of the cap closure of the product carrier to be dosed and a spring internal of the first piece of the device, which determines the stop of lower displacement when the piston body falls on the same.
