Abstract

UNA PIEZA DE FUNDICION DE CABEZA DE CILINDRO DE UNA SOLA PIEZA, QUE TIENE PASADIZOS COLOCADOS DE MANERA FIABLE PARA LA ADMISION DE CARBURANTE, PARA EVACUACION Y PARA REFRIGERANTE, ESTA FORMADO DE VARIOS ELEMENTOS CENTRALES DE UNA SOLA PIEZA INTESENGRANADORES QUE TIENEN UN NUCLEO DE CHAQUETA REFRIGERANTE DE UNA SOLA PIEZA, UN NUCLEO DE ESCAPE DE UNA SOLA PIEZA Y UN NUCLEO DE ADMISION DE CARBURANTE DE UNA SOLA PIEZA, TODOS ELLOS COLOCADOS DE MANERA FIABLE Y SUJETOS ENTRE SI EN UN MONTAJE DE NUCLEO INTEGRAL. ES MEJOR QUE HAYA UN ELEMENTO DE NUCLEO ADICIONAL QUE TENGA VARIAS SUPERFICIES DE APOYO Y CELEBRACION DE NUCLEO QUE CASEN LAS SUPERFICIES INTERCONECTORAS DEL NUCLEO DE CHAQUETA DE AGUA DE UNA SOLA PIEZA, EL NUCLEO DE ESCAPE DE UNA SOLA PIEZA Y EL NUCLEO DE ADMISION DE UNA SOLA PIEZA Y SOPORTE DICHOS NUCLEOS EN SU LUGAR UNO RESPECTO AL OTRO, PUDIENDO TENER EL NUCLEO DE ADMISION VARIAS SUPERFICIES DE INTERCONEXION PARA CERRAR LOS DISTINTOS ELEMENTOS DE NUCLEO EN UN MONTAJE DE NUCLEO UNITARIO. DICHO APARATO DE FUNDICION DE CABEZA DE CILINDRO PUEDEN TENER PAREDES INTEGRALES QUE FORMAN UNA CAVIDAD COLECTORA DE ADMISION LARGA, ABIERTA, EN EL LATERAL DE LA CABEZA DE CILINDRO. LAS PIEZAS DE FUNDICION, INCLUIDAS ESTAS CABEZAS DE CILINDRO, PUEDEN ESTAR PROVISTAS DE CAVIDADES LARGAS, ESTRECHAS, ABIERTAS QUE TIENEN LONGITUDES QUE SON MUCHAS VECES SUS ANCHURAS, FORMADAS DE PAREDES UNIFORMES DE METAL DE FUNDICION, SIN ELEMENTOS EXTRAÑOS, MEDIANTE EL USO DE UN ELEMENTO DE NUCLEO DE DOS PIEZAS LARGO, ESTRECHO QUE TIENE UNA PARTE DE SOPORTE DEL ELEMENTO DE NUCLEO INTERIOR QUE ESTA COLOCADA PARA PERMITIR EL ESCAPE DEL GAS GENERADO DURANTE LA FUNDICION A LA ATMOSFERA. DICHAS CAVIDADES ABIERTAS LARGAS Y ESTRECHAS ESTAN HECHAS DE PAREDES METALICAS DE FUNDICION QUE PERMITEN SER UTILIZADAS COMO RESERVAS DE FLUIDO HIDRAULICO FIABLES QUE CONTIENEN PRESIONES EN EXCESO DE 3.000 PSI (LIBRAS POR PULGADA CUADRADA).
