초록 ▼

A nozzle for delivering texturized fibrous material into a chamber of a muffler has a body including a texturized fibrous material passageway and a separate directional jet passageway. A method of filling a chamber of a muffler with texturized fibrous material includes the steps of extending a wand into the muffler so that a nozzle on the wand is received in the chamber, discharging a stream of texturized fibrous material into the chamber from a first passageway of the nozzle and discharging a directional jet into the stream of texturized fibrous material from a second passageway of a nozzle whereby the stream of texturized fibrous material is redirected into a desired filling direction to more efficiently fill the chamber.

1. An apparatus for filling a muffler with texturized fibrous material, comprising: a texturizing gun;a first air source providing air under pressure to said texturizing gun;a fibrous material source providing fibrous material to said texturizing gun;a secondary air source also providing air under pressure; anda wand and nozzle assembly having proximal end and a distal end with an axis A extending between said proximal end and said distal end, said wand and nozzle assembly including: a first passageway for receiving texturized fibrous material from said texturizing gun and directing a stream of texturized fibrous material toward a chamber of said muffler along a first path; anda second passageway for receiving air under pressure from said second air source and directing a directional jet along a second path into said stream of texturized fibrous material so as to redirect said stream of texturized fibrous material in a desired filling direction,wherein said first passageway is operable to discharge said stream of texturized fibrous material toward said chamber at an angle of at least 90 degrees relative to said axis A, andwherein said desired filing direction resulting from impacting said stream of texturized fibrous material with said directional jet forms an acute angle of less than 90 degrees relative to said axis A. 2. The apparatus of claim 1, wherein said desired filling direction forms an acute angle D with said axis A. 3. The apparatus of claim 1 wherein said second path is parallel to said axis A. 4. A method of filling a chamber of a muffler with texturized fibrous material, comprising: extending a wand into said muffler so that a nozzle on said wand is received in said chamber, said nozzle including a proximal end and a distal end with an axis A extending between said proximal end and said distal end;discharging a stream of texturized fibrous material at an angle of at least 90 degrees relative to said axis A toward said chamber from a first passageway of said nozzle; anddischarging a directional jet into said stream of texturized fibrous material from a second passageway of said nozzle to redirect said stream of texturized fibrous material into an acute angle of less than 90 degrees relative to said axis A. 5. The method of claim 4, further comprising: inserting said nozzle into said muffler through a pipe; andextending said nozzle from an end of said pipe so as to project into said chamber. 6. The method of claim 5, including rotating said nozzle about said axis A while discharging said stream of texturized fibrous material. 7. The method of claim 6, further including sealing an opening in an internal baffle of a muffler by plugging said opening with said distal end of said nozzle. 8. The method of claim 7, further including plugging said end of said pipe with said proximal end of said nozzle. 9. The method of claim 4, further including providing said nozzle in said chamber adjacent a first wall and directing texturized fibrous material from said nozzle toward a second, opposite wall so as to more evenly distribute and efficiently fill said chamber in the texturized fibrous material. 10. The method of claim 4, further including increasing or decreasing pressure of said directional jet relative to pressure of said stream of texturized material in order to adjust a filling direction of said redirected stream of texturized fibrous material. 11. The method of claim 10, further including changing said filling direction during filling of said chamber with texturized fibrous material.
