Abstract

UNA BOQUILLA DE INYECCION DE COMBUSTIBLE COMPRENDE UN COMPONENTE DE VALVULA ACCIONADA POR PRESION DE COMBUSTIBLE (10A) QUE SE INCLINA EN CONTACTO CON UN ASIENTO (9) MEDIANTE UN MEDIO FLEXIBLE (11). LA BOQUILLA COMPRENDE TAMBIEN UN COMPONENTE DE VALVULA DE REBOSAMIENTO (22) QUE TIENE UNA CABEZA (22A) QUE SE INCLINA EN CONTACTO CON UN ASIENTO MEDIANTE UN MEDIO FLEXIBLE (11). LA CABEZA DE LA VALVULA DE REBOSAMIENTO SE LEVANTA DEL ASIENTO MEDIANTE LA APLICACION DE COMBUSTIBLE A PRESION A UNA PARTE DE EMBOLO (24) DEL COMPONENTE DE VALVULA DE REBOSAMIENTO. CUANDO LA CABEZA DE LA VALVULA DE REBOSAMIENTO SE LEVANTA DEL ASIENTO, EL COMBUSTIBLE SE DERRAMA DE LA ENTRADA DE LA BOQUILLA A UN SUMIDERO.
