Abstract:
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.

Claim (Index 1):
Pneumatic braking system for a railway vehicle, comprising a pneumatic circuit for supplying a pneumatic braking pressure to at least one brake cylinder, including\n 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 said at least one brake cylinder, said 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 said at least one brake cylinder, independently of the conditions of said solenoid charging and discharge valves; the system comprising further an electric emergency line on which in normal operation there is a voltage which drops when emergency braking is activated; the system being characterized in that said solenoid brake release valve is coupled to said electric emergency line through at least one controlled electric switch, so that the solenoid brake release valve can be energized by a controlled closure of said switch when a voltage is present on said electric emergency line and the solenoid brake release valve is de-energized when said switch is opened, as well as when the voltage on the electric emergency line drops, independently of the condition of said switch.
