Abstract

EL DISPENSADOR COMPRENDE UN PRIMER (11) CILINDRO, UN PRIMER PISTON (2) HUECO DISPUESTO DESLIZABLEMENTE EN EL PRIMER CILINDRO, UN SEGUNDO CILINDRO (12) COAXIAL CON EL PRIMER CILINDRO (11) Y FORMANDO UNA PROLONGACION DE EL DE MENOR DIAMETRO, TENIENDO LA PARED INTERIOR DEL SEGUNDO CILINDRO (12) UNA CAVIDAD (13) ANULAR HORIZONTAL ALARGADA EN LA UNION DEL PRIMER Y SEGUNDO CILINDROS, UN SEGUNDO PISTON (3) DISPUESTO DESLIZABLEMENTE EN EL SEGUNDO CILINDRO (12), UN VASTAGO (4) VERTICAL DISPUESTO DESLIZABLEMENTE DENTRO DEL PRIMER PISTON (2) Y ENGANCHADA AL SEGUNDO PISTON (3) Y UN MUELLE (6) QUE SE EXTIENDE DENTRO DEL SEGUNDO CILINDRO (13) ENTRE SU EXTREMO INFERIOR Y EL EXTREMO INFERIOR DEL SEGUNDO PISTON (3). EL PRIMER PISTON (2) ESTA DOTADO CON UN ALARGAMIENTO (14) INTERMEDIO, DEFINIENDO SUS EXTREMOS UNA PORCION SUPERIOR (27A) Y UNA PORCION (27B) INFERIOR. LA PORCION SUPERIOR (27A) SE EXTIENDE DESLIZABLEMENTE SOBRE Y DENTRO DEL PRIMER CILINDRO (11) Y LA PORCION INFERIOR (27B) SE EXTIENDE DESLIZABLEMENTE DENTRO DEL PRIMER CILINDRO (11) Y EL SEGUNDO CILINDRO (12). EL ALARGAMIENTO (14) CONECTA PERIFERICAMENTE Y DEFINE UN PRIMER SELLO (S1) SIN FRACTURAS CON LA SUPERFICIE INTERIOR DEL PRIMER CILINDRO (11). EL SEGUNDO PISTON (3) CONECTA PERIFERICAMENTE Y DEFINE UN SEGUNDO SELLO (S2) CON LA SUPERFICIE INTERIOR DEL SEGUNDO CILINDRO (12), ESTANDO SIN FISURAS EL SEGUNDO SELLO (S2) EXCEPTO CUANDO EL SEGUNDO PISTON (3) SE ALINEA CON Y, SEPARADA DE, LA CAVIDAD ANULAR (13). LA PORCION INFERIOR (27B) DEL PRIMER PISTON (2) ESTA DOTADO CON UNA PLURALIDAD DE RANURAS VERTICALES (30) O RANURAS (31) HELICOIDALES.THE DISPENSER COMPRISES A FIRST (11) CYLINDER, A FIRST PISTON (2) HOLLOW ARRANGED SLOWLY IN THE FIRST CYLINDER, A SECOND CYLINDER (12) COAXIAL WITH THE FIRST CYLINDER (11), FORMING A PROLONGATION OF IT OF THE LOWEST DIAMETER, INSIDE WALL OF THE SECOND CYLINDER (12) A HORIZONTAL CANCELL (13) NARROWED IN THE JOINT OF THE FIRST AND SECOND CYLINDERS, A SECOND PISTON (3) SLIDELY IN THE SECOND CYLINDER (12), VERTICALLY DISPOSED OF THE FIRST PISTON (2) AND ATTACHED TO THE SECOND PISTON (3) AND A SPRING (6) THAT EXTENDS WITHIN THE SECOND CYLINDER (13) BETWEEN ITS LOWER END AND THE LOWER END OF THE SECOND PISTON (3). THE FIRST PISTON (2) IS EQUIPPED WITH AN INTERMEDIATE EXTENSION (14), DEFINING ITS ENDS A SUPERIOR PORTION (27A) AND A LOWER PORTION (27B). THE UPPER PORTION (27A) SLIDELY EXTENDS OVER AND INSIDE THE FIRST CYLINDER (11) AND THE LOWER PORTION (27B) SLIDELY EXPANDS INSIDE THE FIRST CYLINDER (11) AND THE SECOND CYLINDER (12). THE EXTENSION (14) CONNECTS PERIPHERALLY AND DEFINES A FIRST SEAL (S1) WITHOUT FRACTURES WITH THE INNER SURFACE OF THE FIRST CYLINDER (11). THE SECOND PISTON (3) PERIPHERALLY CONNECTS AND DEFINES A SECOND SEAL (S2) WITH THE INNER SURFACE OF THE SECOND CYLINDER (12), THE SECOND SEAL (S2) IS WITHOUT FISSURES WHEN THE SECOND PISTON (3) IS ALIGNED WITH AND, SEPARATED OF, THE RING CAVITY (13). THE LOWER PORTION (27B) OF THE FIRST PISTON (2) IS EQUIPPED WITH A PLURALITY OF VERTICAL SLOTS (30) OR SLOTS (31) HELICAL.
