Abstract

BOMBA DE INYECCION DE COMBUSTIBLE LIQUIDO. UNA BOMBA DE INYECCION DE COMBUSTIBLE LIQUIDO DEL TIPO DE DISTRIBUIDOR GIRATORIO, TIENE UN PISTON 21 ACCIONABLE POR LA PRESION DEL FLUIDO, QUE ESTA CONECTADO CON UN ANILLO DE LEVAS DE LA BOMBA CON EL FIN DE AJUSTAR LA SINCRONIZACION. LA CIRCULACION DEL FLUIDO HACIA EL INTERIOR Y HACIA EL EXTERIOR DE UNA EXTREMIDAD DEL FLUIDO QUE CONTIENE EL PISTON SE CONTROLA POR MEDIO DE UN ELEMENTO DE VALVULA 29 QUE PUEDE DESLIZARSE EN UN AGUJERO FORMADO EN EL PISTON. EL ELEMENTO DE VAVULA ESTA EQUILIBRADO POR LA PRESION Y SU POSICION ESTA DETERMINADA POR MEDIO DE PISTONES DE CONTROL 41, 43 EN RESPUESTA A LAS VARIACIONES DE PRESION DEL FLUIDO. EL PISTON ESTA SOMETIDO A FUERZAS DE REACCION CUANDO LOS SEGUIDORES DE LEVA DE LA BOMBA ENTRAN EN CONTACTO CON LAS CARAS DELANTERAS DE LOS LOBULOS DE LA LEVA Y UNA VALVULA ESFERICA 39 SE OPONE AL MOVIMIENTO DEL PISTON. UNAS FUERZAS DEREACCION OPUESTAS SE PRODUCEN CUANDO LOS SEGUIDORES DE LEVA SE DESPLAZAN POR ENCIMA DE LASCRESTAS DE LOS LOBULOS DE LA LEVA Y LA CIRCULACION RESTRINGIDA PROCEDENTE DE LA OTRA EXTREMIDAD DEL CILINDRO SE OPONE AL MOVIMIENTO DEL PISTON.
