Abstract
An intake silencer device is described herein. The intake silencer device includes an outer housing and a plurality of sequential arranged expansion chambers separated by walls. The intake silencer device further includes an inner tube positioned in each of the sequential chambers, each of the inner tubes including an opening providing fluidic communication between an interior of the tube and the corresponding expansion chamber, a size of the openings increasing in size sequentially in a downstream direction.
Claims20
An intake silencer device comprising:
- a cylindrical outer housing;
- a plurality of sequentially arranged expansion chambers separated by walls;
- and
- an inner tube positioned in each of the sequential expansion chambers, each of the inner tubes including an opening providing fluidic communication between an interior of the tube and the corresponding expansion chamber, a size of the openings increasing in size sequentially in a downstream direction;
- wherein the inner tube positioned in the expansion chamber at a downstream end of the housing extends only partially from the wall of said expansion chamber and does not axially span a length of the expansion chamber in its entirety, the opening of the inner tube positioned in the expansion chamber at the downstream end of the housing being circular and aligned with a central axis of each of the inner tubes, and
- wherein an inner radius of the cylindrical outer housing does not vary along a length spanning the expansion chambers.
