Patent ID: 7344145

Claim:
A device for treating compressed air, to be installed in a motor vehicle, the device comprising: an air inlet for air coming from a compressed-air source; at least one air outlet connected to at least one reservoir configured to supply a service brake system; a set of electropneumatic components distributing compressed air from the compressed-air source bound for the at least one reservoir; an electronic command and control unit, configured to operate said set of electropneumatic components, the command and control unit being connected to a communication bus; at least one supplementary air outlet for directly providing compressed air at a control pressure to at least one actuator of a pneumatic suspension system of one axle; a supplementary set of electropneumatic components associated with and upstream of the supplementary air outlet, the set receiving compressed air at a supply pressure and applying the control pressure to the compressed air to selectively fully operate the at least one actuator; and said command and control unit comprising operating means configured to operate the supplementary set of electropneumatic components based on the information originating from the communication bus, whereby full operation of the at least one actuator is directly controlled by the device.
