Air supply system

Abstract

An air supply system is provided that can reduce noise of a compressor and over a wider frequency band, along with the space and cost. The air supply system includes a compressor that draws in gas to discharge the drawn in gas at an increased pressure, an intake flow path 43 in which the gas drawn in by the compressor flows, a discharge flow path 44 in which the gas discharged from the compressor 41 flows, and rectification apparatuses 45 A and 45 B that are disposed in the vicinity of the compressor 41 in the intake flow path 43 and the discharge flow path 44 , respectively, and that rectify gas flowing therein.

1 . An air supply system, comprising: 
 a compressor which draws in gas to discharge the gas drawn in, at an increased pressure;    an intake flow path through which the gas drawn in by the compressor flows;    a discharge flow path through which the gas discharged from the compressor flows; and    a first rectification apparatus disposed in the vicinity of the compressor in the discharge flow path and rectifies the gas flowing therein.    
   
   
       2 . The air supply system according to  claim 1 , further comprising: a second rectification apparatus disposed in the vicinity of the compressor in the intake flow path and rectifies the gas flowing therein.  
   
   
       3 . The air supply system according to  claim 1 , 
 wherein the first rectification apparatus is abutted with a discharge outlet of the compressor.    
   
   
       4 . The air supply system according to  claim 1 , 
 wherein the first rectification apparatus has a maximum length in a direction along which the discharge flow path extends resulting in a pressure drop by the first rectification apparatus within an acceptable range.    
   
   
       5 . The air supply system according to  claim 1 , 
 wherein the first rectification apparatus has a honeycomb structure comprised of a plurality of rectification channels extending along the discharge flow path, and a number of the rectification channels to a cross-sectional area of the discharge flow path is maximum resulting in the pressure drop by the first rectification apparatus within the acceptable range.    
   
   
       6 . An air supply system, comprising: 
 a compressor which draws in gas to discharge the gas drawn in, at an increased pressure;    an intake flow path through which the gas drawn in by the compressor flows;    a discharge flow path through which the gas discharged from the compressor flows; and    a rectification apparatus disposed in the vicinity of the compressor in the intake flow path and rectifies the gas flowing therein.
