Abstract

A servo reinforcer assembly for vehicle brake systems, in which a movable wall is subjected to differential pressure controlled by valve means, which comprise a valve body provided with an axial hole, inside which a valve control member works with a non-round cross-sectional portion, a support clapper for allowing the pallet to pass over said portion, the shapes of said portion and opening being such that the plate is prevented from passing over the portion in the reverse direction when the plate passes over the plate. Portion in the reverse direction when the plate has been rotated a certain suitable angle with respect to the opening, characterized in that the valve body is provided with a recess (48) disposed substantially in transverse position, inside which a key (49) provided is received of free play connection with the valve control member (21) and which cooperates with the diaphragm support plate (7) to prevent rotate with respect to the aforementioned portion (41) to a position in which the plate can pass over said portion, having the appropriate means (56) to keep the key in its position.
