Abstract : A muffler for an air powered turbine drive includes a cone section made of a perforated metal, a plurality of layers of sintered material on the inner surfaces of the cone section, an inner housing section substantially surrounding the cone section, an inner baffle wall between the inner housing section and the inner cone section, and an outer housing section substantially surrounding the inner housing section. Air entering the muffler through the cone section passes outwardly through the walls of the cone section and is then redirected several times before passing outwardly from the outer housing section in order to attenuate the noise in the air leaving the muffler without creating excessive muffler pressure.
