Abstract

Cilindro de mando, en particular para sistemas de frenado hidráulico de vehículos automóviles, que comprende un taladro (12) formado por un cuerpo (10) y en el que desliza, al menos, un pistón (20) primario provisto de un conducto (58) de compensación, susceptible de poner en comunicación una cámara (24) de presión del cilindro de mando con un depósito de fluido a presión cuando el cilindro de mando está en posición de reposo, siendo interrumpida dicha comunicación por un segundo pistón (16) durante el accionamiento del cilindro de mando por un vástago (18) de mando, que actúa sobre el segundo pistón (16) y que desliza en el taladro (12) del cilindro de mando, solicitando un primer muelle (28) de compresión al pistón (20) primario hacia una posición trasera de reposo, estando dispuesto un segundo muelle (42) de compresión entre el pistón (20) primario y el segundo pistón (16) y solicitando a este último hacia una posición trasera de reposo, siendo la carga elástica previa, en reposo, del primer muelle (28) de compresión superior a la carga elástica previa, en reposo, del segundo muelle (42) de compresión, caracterizado porque las posiciones trasera de reposo del pistón (20) primario y del segundo pistón (16) son definidas por el mismo tope (36) solidario con el cuerpo (10) del cilindro de mando.
