FIELD: engines and pumps.
SUBSTANCE: invention relates to turbo-supercharger driven by exhaust gases for ICE (3). It has bypass channel (4) to bypass the turbine (5). Bypass valve (2) is arranged in bypass channel (4) between pressure exhaust gas pipe (10) and turbine (5) crosswise section (6). Bypass valve (2) is retained axially by valve stem while its plate in as-closed state can abut on valve seat so that valve plate side connected with valve stem faces the pressure line (10). Besides, moving pressure plate displacing to turbosupercharger case recess (13) is made at bypass valve.
EFFECT: decreased bypass valve driving force.
