Abstract

Un dispositivo inyector para la entrega de líquido desde una fuente de alta presion, que comprende un alojamiento, una cámara de presion 2 que consta de un cilindro de presion 4 para acomodar al menos un piston en el mismo y que posee una abertura de extremo frontal 6 para la eyeccion del líquido, la cámara de presion posee resistencia suficiente para mantener la presion del líquido. El dispositivo además comprende una cámara de almacenamiento 16 separada de la cámara de presion para el líquido o componentes precursores de líquido, y un conducto 22 entre la cámara de presion y la cámara de almacenamiento. Se dispone un mecanismo de presurizacion 26 n el alojamiento para aplicar fuerza, directa o indirectamente, sobre el piston en el cilindro de presion, para crear dicha presion de líquido. La cámara de presion, el piston y al menos una parte del conducto están dispuestos como una unidad, en donde dicha unidad y el alojamiento poseen las correspondientes partes de sujecion que permiten la fijacion removible de la unidad respecto al alojamiento en una posicion que permita la conexion de fluido entre la cámara de almacenamiento y la cámara de presion a través del conducto, y permitiendo que el mecanismo de presurizacion actue sobre el piston.An injector device for delivering liquid from a high-pressure source, comprising a housing, a pressure chamber 2 consisting of a pressure cylinder 4 to accommodate at least one piston therein and having a front end opening 6 For the ejection of the liquid, the pressure chamber has sufficient strength to maintain the pressure of the liquid. The device further comprises a storage chamber 16 separated from the pressure chamber for the liquid or liquid precursor components, and a conduit 22 between the pressure chamber and the storage chamber. A pressurization mechanism 26 n is provided in the housing to apply force, directly or indirectly, on the piston in the pressure cylinder, to create said liquid pressure. The pressure chamber, the piston and at least a part of the conduit are arranged as a unit, wherein said unit and the housing have the corresponding fastening parts that allow the removable fixing of the unit with respect to the housing in a position that allows the fluid connection between the storage chamber and the pressure chamber through the conduit, and allowing the pressurization mechanism to act on the piston.
