Abstract
A muffler apparatus has an outer housing for being attached to a motorcycle or the like. Disposed internally of the housing is a passageway assembly having a connecting tube with a flare for being connected to an exhaust pipe and a perforated tube connected to the connecting tube. A solid tube, opened at both of its ends, is rigidly affixed to the interior of the perforated tube in concentric relationship. The solid tube extends through at least a portion of the length of the perforated tube. Alternatively, several solid tubes in either clustered or concentric arrangements may be used in place of the single solid tube.
Claims8
A muffler having an entrance port and an exit port for being coupled to a source of noise having a gas passageway member through which gas flows, the muffler comprising:
- a housing for being coupled at one of its ends to the gas passageway member;
- a perforated tube attached to the interior of the housing for interiorly of the perforated tube a first straight unobstructed passageway through the housing;
- and
- at least one solid non-perforated tube, each nonperforated tube opened at both of its ends for defining a second straight unobstructed passageway through the nonperforated tube, the non-perforated tube being positioned longitudinally in the first straight unobstructed passageway whereby the gas flows freely without substantial obstruction through both the first and second unobstructed passageways between the entrance and exit ports of the muffler.
An improved muffling device between an entrance port and an exit port having interiorly a substantially straight first unobstructed gas passageway through which a gas flows for muffling the sound generated by a source of noise, the improvement comprising at least one open-ended solid, non-perforated tube longitudinally attached in the interior of the first unobstructed gas passageway, each a non-perforated tube having a substantially straight second unobstructed gas passageway therethrough whereby the gas flows freely without substantial obstruction through both the first and second unobstructed gas passageways between the entrance and exit ports of the muffler device.
