Abstract

Etapa de control de una servoválvula del tipo de chorro que comprende un eyector (20; 120) para expulsar un chorro de fluido y que es desplazable enfrente de un deflector (6; 106) capaz de generar un diferencial de presión que se puede explotar para desplazar un distribuidor (3) de la servoválvula y en la cual el eyector (20; 120) se extiende radialmente en voladizo desde una columna (21; 121), la columna (21; 121) teniendo un primer extremo que se puede empotrar sobre la servoválvula (23; 123) y por el cual el fluido es introducido en el interior de la columna (21; 121), la columna (21; 121) estando provista de un segundo extremo (24; 124) sometido a la solicitación de un motor de par (26; 126) para torcer selectivamente la columna (21; 121) en un sentido o en otro alrededor de una posición de reposo caracterizada por que la columna (21; 121) es de una pieza, el eyector (20; 120) estando fijado en un extremo de una tubería (130) que se extiende radialmente desde la columna (21; 121) estando en comunicación fluídica con un orificio central (22; 122) de la columna (21; 121) por el cual el eyector (20; 120) es alimentado con fluido.
