Abstract

UNA BOMBA DE INYECCION DE COMBUSTIBLE LIQUIDO INCLUYE UN PISTON (21) QUE PUEDE SER DESPLAZADO POR LA PRESION DEL FLUIDO PARA CAMBIAR EL REGLAJE DE UN ANILLO DE LEVAS DEL APARATO CON EL FIN DE MODIFICAR LA SINCRONIZACION DEL SUMINISTRO DE COMBUSTIBLE LIQUIDO. UN ELEMENTO DE PISTON (55) ESTA DISPUESTO CON EL FIN DE SITUAR EL PISTON (21) EN UNA POSICION PARTICULAR CUANDO EL MOTOR ESTA FRIO Y SE NECESITA ACELERACION. EL ELEMENTO DE PISTON PUEDE DESPLAZARSE ANGULARMENTE Y HAN SIDO PREVISTOS UNOS MEDIOS ORIFICIOS (58, 60) Y (56, 59) EN EL ELEMENTO DE PISTON Y EN SU CILINDRO (52) DE TAL MANERA QUE, EN UNA POSICION ANGULAR, LAS EXTREMIDADES OPUESTAS DEL ELEMENTO DE PISTON ESTEN SOMETIDAS A LA MISMA PRESION DE FLUIDO Y QUE, EN OTRAS POSICIONES ANGULARES, UNA EXTREMIDAD DEL CILINDRO CONTIENE FLUIDO A UNA PRESION MAS ELEVADA PARA HACER QUE EL ELEMENTO DE PISTON SE DESPLACE A PARTIR DE LA PRIMERA EXTREMIDAD DEL CILINDRO CON EL FIN DE SITUAR EL PISTON EN LA POSICION DESEADA.
