Abstract

Boquilla de inyección de combustible para motores de encendido por compresión, de la clase usada para suministrar combustible a un espacio de combustión de un motor de encendido por compresión y que comprende una cabeza de boquilla formada por un cuerpo cilíndrico escalonado cuyo extremo mayor define una superficie de estanqueidad para cooperar con una superficie de estanqueidad complementaria formada en un extremo de un cuerpo de boquilla, una tuerca de retención cooperante con un escalón del cuerpo cilíndrico y que se une a rosca con el cuerpo de la boquilla para retener a dichas superficies de estanqueidad en contacto estanco, un agujero formado en el cuerpo cilíndrico, un asiento definido alrededor del extremo del agujero alejado del cuerpo cilíndrico y una salida de combustible a partir de dicho extremo del agujero, un miembro de válvula deslizable en el agujero y configurado para cooperar con el asiento con el fin de impedir el flujo del combustible a través de dicha salida, una ranura circunferencial definida en la pared de dicho agujero, al menos un paso de entrada de combustible que se extiende a partir de dicha superficie de estanqueidad hasta dicha ranura, una holgura definida entre el miembro de válvula y la pared del agujero entre la ranura y el asiento, fluyendo el combustible a través de dicha salida y un anillo dispuesto alrededor de dicho cuerpo cilíndrico, estando dicho anillo bajo tensión cuando coopera con el cuerpo con el fin de generar un esfuerzo de compresión en el cuerpo cilíndrico para reducir de este modo el esfuerzo de tracción al que es sometido el material del cuerpo en la región de la ranura circunferencial cuando se suministra combustible bajo presión a través de dicho peso.
