Abstract

La invencion se relaciona con un servomotor neumatico para un frenado asistido, comprendiendo una cubierta rigida (1) en la que una pared divisora a presion movible (2) define una camara frontal (3) y una camara trasera (4) , un piston neumatico (5) viajando con la pared de particion movible (2), un embolo (8), alojado dentro del piston (5) y manejado por una varilla de control (7) y controlando el estado de la valvula de tres entradas (9), medios de transmision de fuerza (10, 13, 17, 18, 31), adaptados para recibir y transmitir al menos una fuerza de asistencia (Fa), impulsada por una cara frontal (51) del piston (5) cuando la valvula (9) pone la camara trasera (4) bajo una segunda presion (Pa), el embolo (8) incluyendo una seccion frontal 881) comprendiendo medios dc retencion (18, 31) para enlazar la seccion frontal (81) del embolo (8) al piston neumatico (5). De acuerdo a la invencion, los medios de retencion comprende un dispositivo unidireccional de embrague (31, 18) para el manejo de los medios de transmision de fuerza (10, 13, 17), independientemente de la varilla de control (7) y de la seccion trasera del embolo (8) cuando son sesgados por el piston neumatico (5), como un resultado de la actuacion de la varilla de control (7), la velocidad de la cual es mayor que, un valor predeterminado.
