Abstract

Improvements in servo boosters for vehicle brake systems, where the load actuation element is movable by the induction of differential pressure of fluid in a mobile internal wall, which divides a booster box into at least two fluid chambers, regulating the differential pressure by a valve comprising a flexible valve closure element which is located within a central bore in the valve body element located within the housing, with one end of the closure element providing a surface adapted to cooperate in a manner selective with a pair of valve seats in order to regulate the differential pressure through said wall, characterized by the fact that the load actuation element mechanically couples to the valve body and that the movement of the load actuation element goes followed by the valve body.
