Noise control type intake hose

Abstract

A noise control type intake hose adapted to improve a noise reducing function to increase the productivity and minimize space in the intake system. The noise control type intake hose comprises an intake hose, a hose expanding part formed at a certain portion of the intake hose, an inner cover formed inside the hose expanding part, a wall formed for obtaining a sealed area between the hose expanding part and the inner cover, and an inner hose protruding out from the inner cover to interconnect the inner side of the intake hose and the sealed area.

1 . A noise control type intake hose, comprising: 
 an intake hose;    a hose expanding part formed at a certain portion of said intake hose;    an inner cover formed inside said hose expanding part;    a wall formed for obtaining a sealed area between said hose expanding part and said inner cover; and    an inner hose protruding out from said inner cover for interconnecting the inside of said intake hose and said sealed area.    
   
   
       2 . The intake hose as defined in  claim 1 , wherein said inner hose is extended in length for reducing low-frequency noise emitted from said intake hose.  
   
   
       3 . The intake hose as defined in  claim 1 , wherein said inner hose is shortened in length for reducing high-frequency noise emitted from said intake hose.  
   
   
       4 . The intake hose as defined in  claim 1 , wherein said hose expanding part, said inner cover, said wall, and said inner hose installed in said intake hose are integrally formed by molding.  
   
   
       5 . A noise control intake hose, comprising: 
 an intake hose configured and dimensioned with an expanded portion; and    an inner member couplable with the expanded portion, wherein said inner member is adjustable in length to function as a resonator and reduce intake noise.
