Abstract

La presente invención se refiere a una placa detectora de orificio en un inyector de combustible del tipo utilizado para descargar combustible hacia ua cámara de combustión de un motor de combustión internal, la placa directora de orificio siendo de una configuración circular con una superficie de aguas arriba y una superficie opuesta de aguas abajo y que tiene un eje central, y una pluralidad de pasajes de orificio pasantes espaciados, que tienen la entrada de los mismos en la superficie de aguas arroba colocada en una circunferencia de un primer círculo colocado concéntrico con respecto al eje central y que se extiende hacia adentro y hacia abajo con cada uno de los pasajes terminando en una abertura de sañoda en la superficie de aguas abajo que está colocada sobre una circunferencia de un segundo círculo que está colocado concéntrico a dicho eje central y que es de un radio menor que el primer circulo estando colocada cada abertura de salida a una distancia predefinida en la misma abertura de salida a una distancia predefinida en la misma dirección alrededor de la circunferencia del segundo circulo a partir de un punto de dicha circunferencia del segundo circulo a partir de un punto de dicha circunferencia en el cual una línea radial desde la entrada de aguas arriba del pasaje respectivo hacia el eje central intersecta el segundo circulo de modo que cuando el inyector del combustible se utiliza para descargar combustible a partir del mismo, cada uno de los pasajes de orificio dirige una corriente de combustible hacia el eje central caracterizado en que el eje de cada uno de los pasajes del orificio esta colocado en for ma paralela a y separado del plano respectivo que se extiende a través del eje central una distancia menor que la mitad del diámetro de dicho pasaje de orificio, de forma que las corrientes de combustible producidas desde los pasajes de orificio durante el uso del inyector del combustible electromagnético, parcialmente de intersectan una sobre la otra y se combinan para producir un patrón de rociadura cónico angosto, hueco, de combustible, que tiene un ángulo incluído predeterminado, de aproximadamente 10 a 20 grados.
