Abstract

UN APARATO DE BOMBEO DE COMBUSTIBLE PARA EL SUMINISTRO DE COMBUSTIBLE A UN MOTOR DE COMBUSTION INTERNA QUE TIENE UNA PLURALIDAD DE EMBOLOS DE BOMBEO (19) ALOJADOS EN UNAS CAVIDADES RESPECTIVAS (17). LOS EMBOLOS SE PUEDEN MOVER HACIA ADENTRO DE LAS CAVIDADES PERO DURANTE TAL MOVIMIENTO UNO DE LOS EMBOLOS SE MUEVE A UNA POSICION EXTERIOR EN QUE UN CONDUCTO PARA EL SUMINISTRO DE COMBUSTIBLE (21) QUE SE COMUNICA CON UN CONDUCTO DE SUMINISTRO DE COMBUSTIBLE (21) QUE SE COMUNICA CON UN ORIFICIO DE SALIDA DEL COMBUSTIBLE (22) QUEDE AL DESCUBIERTO RESPECTO A LA CAMARA DE TRABAJO DE BOMBEO (20) DEFINIDA EN LOS EXTREMOS INTERIORES DE LAS CAVIDADES. CADA CAVIDAD TIENE UN CONDUCTO DE SUMINISTRO ASOCIADO A LA MISMA. HAY UN DISCO DE LEVAS (25) PARA PROVOCAR EL MOVIMIENTO HACIA ADENTRO DE LOS EMBOLOS Y EL DISCO DE LEVAS TIENE UNOS LOBULOS DE LEVAS (26) EN SU SUPERFICIE PERIFERICA INTERNA SI BIEN A UNO DE LOS LOBULOS DE LEVAS LE SUSTITUYE UNA RANURA QUE PERMITE QUE LOS EMBOLOS SE MUEVAN HACIA AFUERA POR TURNOS PARA DISTRIBUIR EL COMBUSTIBLE A LOS ORIFICIOS DE SALIDA QUE CUANDO SE ENCUENTRAN EN FUNCIONAMIENTO QUEDAN CONECTADOS A LAS BOQUILLAS DE INYECCION DE UN MOTOR.
