Abstract
The assembly comprises a body wherein there are defined a chamber, a supply valve adapted to connect the chamber to a pressure source or to the atmosphere, and a vent valve adapted to allow or prevent the connection of the chamber to the atmosphere. The valves are provided with control solenoids to which respective electronic switches are coupled. The assembly also comprises electronic control devices adapted to provide, as a function of the values of at least one input signal, logic control signals to the electronic switches so as to control, through the valves, the value of the pressure in the chamber. The control means comprise two processing and control devices independent of one another, both receiving the input signal and designed to execute strategies for controlling the pressure in the chamber, equivalent to one another.
