Abstract
Complementary dished members cooperate to define an elongated shell that is divided into front and rear compartments by a partition wall. A U-shaped stamping divides the rear compartment into three aligned and communicated chambers and reinforces the rear shell wall. Gas enters an end one of the chambers through a perforated inlet tube that extends through the rear shell wall, thence flows successively through the other two chambers and into the front compartment. The inlet tube, the U-shaped stamping and the partition wall are so apertured that in the course of such flow the gas is alternately dispersed and recombined. The front compartment is longitudinally divided into two elongated passages through which gas flows lengthwise, in succession, in passing to an outlet in the front shell wall.
