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.

Vehicle braking assembly

Electro-pneumatic assembly, particularly for a pneumatic braking installation for railway vehicles

The pneumatic braking system comprises a pneumatic circuit for supplying a pneumatic braking pressure to at least one brake cylinder, and includes a pneumatic solenoid charging valve and a pneumatic solenoid discharge valve adapted to cause an increase and a reduction, respectively, of the pneumatic pressure acting upon the at least one brake cylinder, the solenoid valves being controlled by an electronic braking control unit; a solenoid brake release valve adapted to cause, when energized, a complete discharge of the pneumatic pressure applied to the at least one brake cylinder, independently of the conditions of the solenoid charging and discharge valves; and an electric emergency line on which in normal operation there is a voltage which drops when emergency braking is activated.
