FIELD: machine building.
SUBSTANCE: proposed diffuser assembly is arranged at turbo machine radial-flow compressor outlet and comprises diffuser with inlet and outlet ring flanges integrated by vanes and distributor with multiple vanes at radially inner circular wall surrounded by outer casing. Inlet ring flange radially outer edge rests on said outer casing. Elastically deformable means are arranged between distributor vane radially outer edges to impede air leaks between outer casing and radially outer vane edges. Said elastically deformable means comprises annular sheet spaced from outer casing, its part resting on radially outer vane edges and its edge resting on casing. Another invention of this set relates to elastically deformable annular sheet incorporated with aforesaid diffuser shaped to truncated cone with taper edges. One more invention relates to turbojet or turboprop incorporating above described diffuser.
EFFECT: decreased vibration, higher operating performances.
