Abstract

Un servofreno de vacio mejorado, para uso de los vehículos automóviles, el cual tiene una caja de vacio en la que hay un tabique móvil y un tubo que une a las superficies de los extremos, dividiendo el tabique móvil a la paja de vacia en la cámara de vacío en una cámaras de vacío en una cámara de vacio y auna cámara de trabajo siendo la presión de la cámara de trabajo controlable por medio de una válvula, y en la que une una válvula, y en que una fuerza que es proporcional a la diferencia de presión de una y otra cámara actúa sobre el tabique móvil, el cual tiene un cierre estando y puede deslizarse con relación al tubo, estando mecánicamente conectado al alojamiento de la válvula del interior de tubo por medio de unos miembros transversales guiados en unas ranuras axiales que tiene el tubo, caracterizado porque la parte del tubo (10) que es interior a la cámara de vacío (31) tiene unas ranuras longitudinales (30) porque del lado del vacío del tabique móvil (34, 35) hay dispuestos unos miembros transversales 841), porque como cierre hermético entre el tabique móvil 834) y el tubo (10) hay un diafragma arrollable (35) el cual cubre con estanquidad las ranuras longitudinales (30) al desplazarse el tabique móvil hacia la cámara de vacío.
