    To reduce the speed of air being sucked towards a compressor turbine wheel, typically an exhaust gas supercharger turbine for an internal combustion engine, guide vanes (18) are located in the path of air being supplied to an inlet (3) of the compressor (1) which are positioned to impart a rotating component of motion to the air stream of air column being supplied to the compressor, the guide vanes extending essentially perpendicularly to the plane of radially positioned damping elements (14), while being inclined with respect to a radial line (19) passing through the axis of rotation of the compressor and, typically, of the housing (8) which has an air-pervious circumferential wall (8). The speed of air being supplied to the turbine thus can be reduced below Mach 1, thereby increasing the efficiency of operation of the turbine while substantially reducing its noise level.

    The inventors refer to turbocompressor building, in particular, to the mufflers of the noise of turbocompressors.
    The aim of the invention is to reduce the noise level.
    FIG. 1 shows a silencer of a turbocharger, a longitudinal section} in FIG. 2 shows the node I in FIG. 11 in FIG. 3 is the same, an embodiment of the metal core in the form of an annular steel plate; FIG. four - ; the same, the embodiment of the metal core with holes mi

    The metal cores 7 are provided with openings 12, and the blades 9 are arranged with axles arranged in them (Fig. 4).
    Blades can be equipped with a shell 13 of sound-absorbing material (Fig. 6.8).
    The blades 9 may be located at equal angles to the radius R of the housing 1.
    The blades 9 can be located to the radius R of the housing 1 at different angles.
    When the turbocharger is operating, the flow
    FIG. 5 is a section A-A in FIG. 1, of the working fluid through the air filter making the blades flat, in FIG. 6 is the same embodiment of the blades of constant thickness in FIG. 7 - the same, the embodiment of the blades profile t | in fig. 8 - then 20, an embodiment of the blades, provided with a shell of sound-absorbing material.
    The noise of the turbocharger includes a housing 1 connected to the inlet pipe 2 of the turbocharger, air filter elements 3 located on the periphery of the body 1 and noise absorbing elements located behind them, made in a series of flat annular discs with axial gaps relative to each other and - Nok 4, 5 of the housing 1 and the screws fixed with respect to the latter by means of clamping screws 6, each disk consisting of a metal core 7 and oGi MBKH 8 of sound-absorbing material and provided with an input guide vane 9, and spaced elements 10 are placed in the gaps. axial clearances and are oriented in the axial direction perpendicular to the discs, and in the circumferential direction - at an angle to the radius of the wheel 11.
    In this case, the blades 9 can be flat (Fig. 5).
    The blades 9 may have a constant inu (Fig. 6).
    Each blade 9 can be made in one piece with one of the adjacent cores 7 (FIG. 2).
    Each metal core 7 can be made in the form of an annular steel plate and the blades 9 are attached to one of its sides (FIG. 3).
    The main elements 3 and the noise absorbing elements located downstream enter the inlet of the turbo-compressor 2 and then to the wheel 11 of the turbo-compressor. Due to the presence of the inlet guide vanes 9, the direction of the intake flow of the working fluid is changed, a vortex flow is created, as a result, the input flow rate to the turbo-compressor wheel 11 is reduced, thereby reducing the noise level.
    In addition, the noise level can be reduced by supplying the blades 9 with a shell 13 of sound-absorbing material or, depending on the required distribution of the flow turbulence at the entrance to the wheel 11 of the turbocharger, by varying the angle of the blades to the radius of the housing 1.
