Abstract
A resonator for a vehicle, which reduces intake noise by using a resonance chamber for frequency tuning, includes an outer pipe having a first outer pipe with an inlet for introducing external air and a second outer pipe with an outlet for discharging the air introduced into the inlet to outside, an inner pipe disposed inside the outer pipe and having a plurality of slits for giving a passage of air, and an expansion pipe inserted between the outer pipe and the inner pipe to partition a space between the outer pipe and the inner pipe into a plurality of spaces and thus partition the resonance chamber into a plurality of regions.
Claims14
A resonator for a vehicle, which reduces intake noise by using a resonance chamber for frequency tuning, the resonator comprising:
- an outer pipe having a first outer pipe with an inlet for introducing external air and a second outer pipe with an outlet for discharging the air introduced into the inlet to outside;
- an inner pipe disposed inside the outer pipe and having a plurality of slits for giving a passage of air;
- and
- an expansion pipe inserted between the outer pipe and the inner pipe to partition a space between the, outer pipe and the inner pipe into a plurality of spaces and thus partition the resonance chamber into a plurality of regions.
The resonator for a vehicle according to claim
- wherein there is provided just a single expansion pipe, and
- wherein one end of the expansion pipe is disposed to be spaced apart from the outer pipe by a predetermined distance to form an interval serving as a passage of air.
