Abstract

UN APARATO DE SUMINISTRO DE COMBUSTIBLE PARA SUMINISTRAR COMBUSTIBLE A UN MOTOR DE ENCENDIDO POR COMPRESION COMPRENDE UN ELEMENTO DE DISTRIBUIDOR ROTATORIO (11) QUE TIENE UN PASO DE DISTRIBUCION (13) QUE PUEDE TENER A SU VEZ UNOS PUERTOS DE SALIDA (14) CONECTADOS CON LAS BOQUILLAS DE INYECCION DEL MOTOR. EL COMBUSTIBLE ES SUMINISTRADO AL PASO DE DISTRIBUCION DESDE UN ACUMULADOR (20) BAJO EL CONTROL DE UNA VALVULA (18). EL ACUMULADOR ES CARGADO CON COMBUSTIBLE POR MEDIO DE UNA BOMBA DE ALTA PRESION (8) QUE ES UNA BOMBA ACCIONADA POR UNA LEVA Y EL COMBUSTIBLE ES SUMINISTRADO A LA BOMBA DE ALTA PRESION POR UNA BOMBA DE BAJA PRESION (31). SE PROPORCIONA UNA VALVULA (34) PARA CONTROLAR LA PRESION DE SALIDA DE LA BOMBA DE BAJA PRESION DE MANERA QUE LA CANTIDAD DE COMBUSTIBLE SUMINISTRADO A LA BOMBA DE ALTA PRESION PUEDA SER VARIADA CON EL OBJETIVO DE CONTROLAR LA PRESION DE COMBUSTIBLE DENTRO DEL ACUMULADOR. EL APARATO COMPRENDE ADEMAS UN SEGUNDO ACUMULADOR (73) DESDE EL QUE SE PUEDE SUMINISTRARCOMBUSTIBLE PARA PERMITIR LA DISTRIBUCION DEL COMBUSTIBLE A UNA PRESION INFERIOR.
