초록 ▼

A muffler of the Helmholtz resonator type has a housing surrounding a main gas flow conduit, the gas flow conduit having an apertured zone within the housing wherein apertures extend through the conduit wall, the shape of the conduit wall at the apertured zone being so varied that gas flows through

대표청구항 ▼

A muffler comprising a housing having end plates, stiffeners between the end plates, said stiffeners containing apertures which extend therethrough, a generally circular section conduit extending through said housing and being supported by said stiffeners and said end plates, said housing and conduit defining therebetween a muffler space, an apertured zone extending along part of said conduit between said stiffeners wherein apertures through the conduit wall provide gas flow passages between the space within the conduit and the muffler space, the apertured zone having depressions in the conduit wall which vary its shape from a circular to a non-circular shape which comprises a throat, the dimensions being such that, when gas flows through said conduit, there is a first gas flow from the upstream end of the apertured zone into the muffler space and back into the throat of the conduit, a second gas flow from the downstream end of the apertured zone into the muffler space and back into the throat of the conduit, and a third gas flow from the upstream end of the apertured zone through the muffler space and back into the conduit through some of the apertures which are in the downstream end of the apertured zone.
