Method for filling a muffler cavity

摘要

A method for filling a muffler with a fibrous material is disclosed. The muffler includes partitions which form a first chamber and second chamber, and a first muffler pipe having an outlet end. A filling aperture at one end of the second muffler pipe is positioned in the first muffler chamber. The second muffler pipe has a filling sleeve therein, the filling sleeve having a filling discharge opening that coordinates with the filling aperture of the second muffler pipe. The first muffler chamber is filled with fibrous material by applying a vacuum source to the first muffler pipe, which draws the fibrous material through the filling aperture. The filling aperture of the second muffler pipe is then positioned into the second muffler chamber, and the second muffler chamber is filled in the same manner as the first muffler chamber. The filling sleeve is then removed from the second muffler pipe.

1. A method for filling a muffler with a fibrous material, the muffler including a muffler shell, a first partition which forms a first chamber and a second chamber within the muffler shell, and a first muffler pipe having an outlet end, the outlet end being operatively connected to the first chamber and the second chamber, the method comprising the steps of:
(a) positioning a second muffler pipe in the first muffler chamber, the second muffler pipe having a first end and a second end, the second muffler pipe having a filling aperture, the second muffler pipe having a filling sleeve positioned therein, the filling sleeve having a filling discharge opening that is aligned with the filling aperture of the second muffler pipe, thereby forming a flow path for the fibrous material to flow through the second muffler pipe and into the first muffler chamber, wherein a diameter of the filling sleeve is nearly equal to a diameter of the second muffler pipe; (b) filling the first muffler chamber by applying a vacuum source to the first muffler chamber by way of the outlet end of the first muffler pipe, thereby drawing the fibrous material through the filling aperture; (c) moving and positioning the second muffler pipe into the second muffler chamber; (d) filling the second muffler chamber by applying a vacuum source to the second muffler chamber by way of the outlet end of the first muffler pipe, thereby drawing the fibrous material through the filling aperture; and (e) removing the filling sleeve from the second muffler pipe.
