Abstract

UNA BOMBA DE INYECCION DE COMBUSTIBLE DE TIPO DISTRIBUIDOR TIENE UN PISTON TUBULAR DE BOMBEO PRINCIPAL (14) Y UN PISTON AUXILIAR (25) MANEJABLE DE FORMA SINCRONICA MEDIANTE UNA LEVA (16). TAMBIEN SE PROPORCIONA UNA VALVULA DE DESCARGA MANEJABLE MEDIANTE LA PRESION DEL FLUIDO (26) QUE SE ABRE CUANDO LA PRESION DEL FLUIDO DESARROLLADA POR EL PISTON AUXILIAR (25) SE HACE SUFICIENTEMENTE ALTA. EL FLUIDO DESPLAZADO POR EL PISTON AUXILIAR (25) PROVOCA EL MOVIMIENTO DE UNA LANZADERA (40) Y EL MOVIMIENTO DE LA LANZADERA SE INTERRUMPE PARA PROVOCAR EL FUNCIONAMIENTO DE LA VALVULA DE DESCARGA (26), MEDIANTE UN CIERRE HIDRAULICO QUE SE CREA CUANDO EL MOVIMIENTO DE LA LANZADERA CIERRA UNA TRAYECTORIA DE ESCAPE (49,50) DESDE EL EXTREMO DEL CILINDRO (37) EN EL QUE ESTA SITUADA.
