FIELD: engines and pumps.
SUBSTANCE: gas feed system for radial-flow compressor "dry" gas dynamic seals comprises at least one filter communicated, on one side, with pressure pipeline and, on the other side, by gas feed pipeline. Note here that said communication between filer and pressure pipeline is made up of two parallel pipelines with check valves communicated with pressure pipelines, one upstream of shut-off valve and another one downstream of said valve, while compressor bypass line incorporates gas bleeder pipeline.
EFFECT: feed of cleaned buffer gas in operation at low compression ratio, longer life, ease of maintenance and repair.
