Abstract:
1. A unitary device for treating compressed air, to be installed in an industrial vehicle comprising a motor vehicle able to haul a trailer, including: an air inlet for air coming from a compressed-air source; at least one air outlet connected to a reservoir or reservoirs intended to supply a service brake system; a set of electropneumatic components distributing compressed air from the compressed-air source bound for the reservoir or reservoirs; an electronic command and control unit, to operate said set of electropneumatic components, the command and control unit being connected to a computer communication bus and to various electrical components; a supplementary air outlet for directly providing compressed air at a variable control pressure to an actuator or actuators of a parking brake system of the motor vehicle; a supplementary set of electropneumatic components associated with and upstream of the supplementary air outlet which set receives compressed air at a supply pressure and applies the variable control pressure to the compressed air to selectively fully operate the actuator or actuators; and operating means incorporated into the electronic command and control unit, to operate the supplementary set of electropneumatic components on the basis of information originating from the computer communication bus and/or from various electrical components, whereby full operation of the actuator or actuators of the parking brake system is directly controlled by the device rather than by a dispersed pressure control component.
