Abstract
Tobera de inyección de combustible, para suministrar éste a un motor de encendido por compresión, que comprende un miembro valvular axialmente desplazable dentro de un ánima, cuyo miembro valvular está configurado para su cooperación con un asiento a fin de impedir el flujo de combustible a través de un orificio de salida, un pistón alojado dentro de un cilindro formado como prolongación del ánima, teniendo tales pistón y cilindro un diámetro menor que este ánima y acoplándose el pistón al miembro valvular; medios valvulares para controlar la presión máxima en el extremo del cilindro alejado del ánima y medios de paso que incluyen una válvula sin retorno a través de la cual el combustible desplazado desde el espacio definido por el miembro valvular, el pistón y las paredes del ánima y el cilindro puede fluir hasta el extremo del cilindro alejado del ánima, siendo tal la disposición que, cuando el motor está parado, la fuerza debida a la presión del combustible que actúa sobre el pistón serásensiblemente nula y, al ponerse en marcha el motor, la presión en el extremo del cilindro alejado del ánima ascenderá gradualmente al suministrase combustible al mismo desde dicho espacio, determinando así un incremento en la presión de apertura de la tobera.
