Abstract

SE PRESENTA UN DISTRIBUIDOR DE ADMISION (4) PARA UN MOTOR DE COMBUSTION INTERNA (1) QUE TIENE UNO O MAS CILINDROS, QUE CONSTA DE UN NUMERO DE CONDUCTOS DE ADMISION FIJOS (10) IGUAL AL NUMERO DE CILINDROS. LOS CONDUCTOS DE ADMISION FIJOS (10) SE EXTIENDEN DESDE LOS CILINDROS HASTA UNA CAJA DE DISTRIBUCION (6) DEFINIDA POR UNA PRIMERA Y UNA SEGUNDA MITAD DE UNA CUBIERTA (7, 8) UNIDAS A LO LARGO DE UN PLANO DE SEPARACION (A). LA CAJA DE DISTRIBUCION (6) COMUNICA CON EL EXTERIOR A TRAVES DE UNA CAMARA DE ADMISION (9) OBTENIDA EN LA SEGUNDA MITAD DE LA CUBIERTA (8). LOS CONDUCTOS DE ADMISION FIJOS (10) ESTAN ADAPTADOS PARA COOPERAR CON PARTES MOVILES DE LOS CONDUCTOS (24) QUE ESTA SITUADAS DENTRO DE LA CAJA DE DISTRIBUCION Y PUEDE MOVERSE ENTRE UNA PRIMERA POSICION (B) QUE ESTA EN CONTACTO CON LOS CONDUCTOS DE ADMISION FIJOS (10) PARA FORMAR UN CONDUCTO SIMPLE, LARGO QUE COMUNICA CON LA CAMARA DE ADMISION Y UNA SEGUNDA POSICION (C) EN LA CUAL LAS PARTES MOVILES DE LOS CONDUCTOS (24) DEFINEN UNASEGUNDA CAMARA DE ADMISION (32) CON LOS CONDUCTOS FIJOS (10).
