FIELD: automotive engineering.
SUBSTANCE: device comprises a first valve unit for creating high pressure at the control port of the compressor via compressor control line, a second valve unit to open regeneration line connected to the compressor control line, and a discharge valve unit for discharging the feeding line, and which control port is connected to the regeneration line. Method of compressed air supply device operation includes stages when high pressure is created at the control port of the compressor, the discharge valve unit is opened, the discharge valve unit is blocked and the pressure on the control port of the compressor is released.
EFFECT: improved device reliability.
