Abstract

LA INVENCION SE REFIERE A UN METODO PARA CONTROLAR LA ESTANQUEIDAD EN UNA BOMBA DE INYECCION DE COMBUSTIBLE QUE PRESENTA UNA CARCASA DE BOMBA QUE PUEDE CONECTARSE A LA CARCASA DEL MOTOR. PARA COMPROBAR SU ESTANQUEIDAD, LA SALIDA (44) DE LA BOMBA DE INYECCION DE COMBUSTIBLE, QUE DESEMBOCA EN UN ESPACIO ANULAR (23) DIVIDIDO POR JUNTAS DE ESTANQUEIDAD Y QUE GENERALMENTE SE DESCARGA A TRAVES DE UNA CONDUCCION (28), SE OBTURA CON UNA MATERIA ELASTICA QUE SE DISUELVE CUANDO SE CALIENTA EL COMBUSTIBLE Y QUE, POR SU ELASTICIDAD, GARANTIZA LA ESTANQUEIDAD DEL CIERRE (23) HACIA EL INTERIOR DE LA BOMBA, PERMITIENDO ASI SOMETER DICHO ESPACIO ANULAR (23) A UNA PRESION DE PRUEBA A TRAVES DE LA CONDUCCION (28).
