LOCOMOTIVE COMPRESSED AIR DRYING PLANT Russian patent published in 2007 - IPC B60T17/02 B60T13/26 

FIELD: railway transport.

SUBSTANCE: invention relates to supply of compressed air to pneumatic systems of rolling stock. Proposed plant contains compressor 1 with drive electric motor 2 controlled by pressure relay 3. Connected in succession to compressor 1 are check valve 4, heat exchanger 5, pressure pipeline 7, two parallel-connected absorbers 8, 9 with cutoff valves 10, 11 at input and blowoff valves 14, 15 controlled by electromagnetic valves 16, 17 and check valves 19, 24 at output of each absorber 8, 9. Plant contains also dry air main line with air collector 21. Regeneration air main line with cutoff valve is installed between check valves 19, 24 and absorbers 8, 9. Regeneration air main line is furnished with two-position distributing valve 25 with two inputs, each being connected to output of one of absorbers 8, 9 and one output connected by pipeline 28 through check valve 29 with restrictor 30 parallel to check valve to regeneration air reservoir-accumulator 6 containing heat exchanger 5 connected by one end with compressor 1 and by other end with pressure pipeline 7. Two-position distributing valve 25 is controlled by electromagnetic valves 31, 32 by signals from control unit 33.

EFFECT: increased economy of adsorption plant.
