Abstract

CONJUNTO BOMBA-INYECTOR PARA REALIZAR A LA VEZ EL DOSIFICADO Y LA INYECCION DE COMBUSTIBLE EN UN MOTOR DE COMBUSTION INTERNA. CONSTA DE UN CONDUCTO DE TRANSFERENCIA SITUADO EN EL EMBOLO-AGUJA, CUYO EXTREMO SUPERIOR ESTA EN COMUNICACION CON EL CONJUNTO DE RETORNO DE COMBUSTIBLE Y SU EXTREMO INFERIOR ESTA ABIERTO, CUANDO DICHO EMBOLO-AGUJA SE ENCUENTRA EN SU POSICION ELEVADA, MIENTRAS QUE EN LA POSIOCION BAJA DEL EMBOLO-AGUJA EL EXTREMO INFERIOR DE DICHO CONDUCTO ESTA OBTURADO; DE UN ANILLO DOSIFICADOR MONTADO EN FORMA EN UNA CAMARA ANULAR DEL CUERPO INYECTOR, Y DE UNOS ORGANOS DE REGULACION DE LA POSICION DE DICHO ANILLO DOSIFICADOR, QUE PERMITEN AJUSTAR LA CANTIDAD DE COMBUSTIBLE A INYECTAR.
