Abstract

UN DISPOSITIVO DE INYECCION QUE TRABAJA CON INYECCION PREVIA E INYECCION PRINCIPAL CONTIENE PARA LA INYECCION PREVIA UNA CAMARA (15) DE PRESION FAMILIARIZADA EN UN EMBOLO (8) HUECO. PARA LA INDUCCION DE LA INYECCION PREVIA SE DESPLAZA EL EMBOLO (8) AXIALMENTE PARA SUPERAR UN ESPACIO (A) Y CON ELLO SE DISPONE DEL EFECTO DE UN TOPE, CON LO CUAL UN EMBOLO (13) DE INMERSION REDUCE EL VOLUMEN DE LA CAMARA (15) DE PRESION PARA LA ELEVACION DE LA PRESION DEL COMBUSTIBLE SOBRE LA PRESION DE INYECCION PREVIA. EL PROCESO DE INYECCION PREVIA SE TERMINA CUANDO SE SUPERA EL ESPACIO (A) Y EL EFECTO DE UN TOPE, EVITANDOSE UNA REDUCCION DE PRESION A TRAVES DE UNA VIA DE CORRIENTE LARGA.
