On the other hand, the compressor impeller 20 of side, the other end has multiple blade 20a at peripheral part.This blade 20a is configured in and is arranged at the rear that air guides suction air importing road (air-breathing stream) 24 of shell 14.Suck air importing road 24 to be connected with vortex chamber 25 via compressor impeller 20, and the firing chamber that vortex chamber 25 imports Lu Eryu motor via not shown suction air connects.
The upstream side that above-mentioned exhaust turbine supercharger 10 is sucking air importing road 24 possesses pressurized machine silencing apparatus 30.This pressurized machine silencing apparatus 30 suck for the suction air be arranged on for compressor section compression is inhaled into air import road 24 front end (upstream side), namely suck the device of entrance part upstream side that air imports road 24, and have by make suction air by and to air stream carry out rectification filter function, absorb noise elimination function because sucking the noise that air produces.
In addition, with regard to this pressurized machine with regard to silencing apparatus 30, the air-breathing housing arranged in the mode of the periphery surrounding muffler body 31 (air intake housing) H is connected with the outside air intake duct road (not shown) for importing the low air of temperature from outboard.Therefore, this turbosupercharger 10 becomes the pressurized machine silencing apparatus of the outboard aspirated mode possessing air-breathing housing H.
Like this, pressurized machine silencing apparatus 30 shown in Fig. 1 is configured to, possesses the air-breathing housing H linked with outside air intake duct road, and, by being installed on the air suction inlet of exhaust turbine supercharger (intensifier body) 10, carry out the noise elimination via sucking the air-breathing that air importing road 24 sucks from the outside of the radiation direction being benchmark with the rotor shaft of intensifier body.
And, at the pressurized machine of present embodiment with in muffler body 31, be provided with the multiple sound absorption separators 2 becoming muffler element at the entrance part of air-breathing stream 24.
The periphery being present in the axis of rotor shaft 15 of this sound absorption separator 2 and periphery not opposed with the wall 32,33 of muffler body 31 adopts this metal of aluminium, and around surrounded by the periphery wall Pm be made up of the perforated metal being formed with multiple through hole.In addition, the periphery wall Pm of sound absorption separator 2 is formed with mutually bending round about two curved parts 2a, 2b.Therefore, each sound absorption separator 2 entirety is in roughly Z-shaped section shape.
This sound absorption separator 2 configures in the mode diminished relative to inspiratory flow direction flow path resistance.
Namely, when using the sound absorption separator 2 in present embodiment, with top 2a (the curved part 2a of two of the curved part be configured in roughly Z-shaped section shape, the convex form portion of the curved part of the radial outside in 2b) facing one direction (more specifically, as shown in Figure 5, the top 2a of the curved part of whole sound absorption separators 2 when observing from rotor shaft all towards left (in other embodiments, the top 2a of the curved part of whole sound absorption separator 2 when observing from rotor shaft all towards the right side)) compare, when the top 2a of curved part of the separator 2 that is configured to absorb sound become downstream side, inspiratory flow direction towards (the arrow F3 namely in Fig. 1 towards) time, flow path resistance diminishes.
Therefore, in the pressurized machine silencing apparatus 30 possessing air-breathing housing H, during the observing from rotor shaft of the top 2a of the curved part of the separator 2 that is configured to absorb sound at least partially towards different from other separators 2 that absorb sound.
At this, when being specifically described the configuration of the sound absorption separator 2 in present embodiment, the sound absorption separator 2 of Fig. 1 is configured to, with the axis L of the Suction gas inlet opening Hi of air-breathing housing H (such as, axis by the axis of rotor shaft and the center of Suction gas inlet opening) be border, the top 2a of the curved part of sound absorption separator 2 towards with rotor shaft be benchmark become different towards.In other words, absorb sound separator 2 curved part top 2a towards being configured to centered by axis L, section shape is roughly symmetrical.In this case, the axis L of Suction gas inlet opening Hi is set to the shaft angle degree becoming θ 1 with horizontal line.This shaft angle degree θ 1 is the scope of 0 ~ 90 degree, and the angle θ 2 of outlet side is also from 0 degree to θ 1.Therefore, when shaft angle degree θ 1 is close to 0 degree, in appearance, absorb sound separator 2 curved part top 2a towards sometimes becoming roughly laterally zygomorphic configuration centered by axis L.
In addition, the pressurized machine silencing apparatus 30 of present embodiment also can arrange demarcation strip not interfere the flowing of air-breathing in air-breathing housing with making.Be more preferably, also on the axis L of Suction gas inlet opening Hi and the position contrary with the position of the Suction gas inlet opening Hi in air-breathing housing arranges demarcation strip 40, thus the flowing interfering air-breathing can be prevented.
