1.01 Air compressor
2.01 Pressure regulation valve
4.03 Four circuit protection valve
a Supply pressure
Operation
The air, compressed by the compressor (1.01) is pushed into the pressure regulation valve (2.01).
After the regulation of the pneumatic pressure is done by the pressure regulation valve (2.01), the compressed air goes to the four circuit valve (4.03) which distributes it to the diverse pneumatic circuits of the brake system (service brake, parking brake, auxiliary circuits etc.), as well as guarantees a minimal pressure on all circuits.
