Abstract

UNA VALVULA QUE CONSTA DE UN CUERPO DE SOPORTE CILINDRICO (1) CON UNA PRIMERA CAVIDAD AXIAL (3) QUE ALOJA UN ELECTROIMAN (4) Y UN NUCLEO (7), Y UN ORIFICIO AXIAL (5) QUE SE COMUNICA CON LA CAVIDAD (3) Y ALOJA UN ANCLAJE (8) INTEGRADO EN UN ENCHUFE MOVIL (9); Y UNA BOQUILLA (12) FIJADA AL CUERPO DE SOPORTE (1) Y EN LA CUAL ESTA FORMADO UN ORIFICIO PARA LA SALIDA DEL COMBUSTIBLE (13) CONTROLADO POR EL ENCHUFE MENCIONADO (9); SE CARACTERIZA PORQUE EL CUERPO DE SOPORTE (1) PRESENTA UNA SERIE DE ORIFICIOS (25) DISEÑADOS PARA PERMITIR LA COMUNICACION EXTERNA, A TRAVES DE LA SUPERFICIE LATERAL (2) DEL CUERPO DE SOPORTE (1), DEL ORIFICIO AXIAL FORMADO DENTRO DEL PROPIO CUERPO (1).A VALVE CONSISTING OF A CYLINDRICAL SUPPORT BODY (1) WITH A FIRST AXIAL CAVITY (3) WHICH HOUSES AN ELECTROMAGNET (4) AND A NUCLEUM (7), AND AN AXIAL HOLE (5) THAT COMMUNICATES WITH THE CAVITY (3 ) AND LODGES AN ANCHOR (8) INTEGRATED IN A MOBILE PLUG (9); AND A NOZZLE (12) ATTACHED TO THE SUPPORT BODY (1) AND IN WHICH A HOLE FOR THE FUEL OUTPUT (13) IS FORMED, CONTROLLED BY THE MENTIONED PLUG (9); IT IS CHARACTERIZED BECAUSE THE SUPPORT BODY (1) PRESENTS A SERIES OF HOLES (25) DESIGNED TO ALLOW EXTERNAL COMMUNICATION, THROUGH THE LATERAL SURFACE (2) OF THE SUPPORT BODY (1), OF THE AXIAL HOLE FORMED WITHIN THE OWN (one).
