摘要： A sound deflecting muffler for deflecting and absorbing sound waves associated with exhaust gases of an internal combustion engine includes a casing having a muffler body defining an interior area and defining an inlet opening operatively connected to the internal combustion engine for receiving exhaust gases into the interior area and defining an outlet opening in communication with the interior area for directing the exhaust gases downstream from the interior area. The casing includes a pair of sound baffles that define a flow path for the exhaust gases flowing between the inlet and outlet of the muffler body, each sound baffle being perforated and having an arcuate configuration such that the flow path narrows at a midpoint. A first sound deflector is positioned in the flow path proximate the inlet end so as to deflect a portion of the exhaust gases toward the pair of sound baffles.

摘要： An exhaust muffler in which the anti-scattering property of a sound deadening element is high and for which shaping is not required and a sound deadening element for use with the exhaust muffler. An exhaust muffler includes an expansion chamber into which exhaust gas of an engine is introduced, and a sound deadening element in which the expansion chamber is inserted. The sound deadening element is configured from a knitted article formed by knitting continuous fibers of glass fiber. The exhaust muffler further includes an inner pipe inserted in a spaced relationship from an inner circumferential wall of the expansion chamber in the expansion chamber and configured to introduce the exhaust gas therethrough. The sound deadening element is disposed between an outer circumferential wall of the inner pipe and the inner circumferential wall of the expansion chamber.

摘要： A muffler (1) for an exhaust system of a motor vehicle internal combustion engine has a housing (2), with an exhaust gas inlet (4) and an exhaust gas outlet (5), including a circumferentially extending jacket (16) and end panels (14, 15) each axial ends. A chamber (18) in the housing interior (3), through which exhaust gas flows during operation, is axially limited by intermediate panels (20, 21) at axial ends. The thermal load on the jacket (16) is reduced with an insulating shell (29), arranged in the housing interior, extending in the circumferential direction (17) along the jacket (16). The two intermediate panels (20, 21) are supported on the insulating shell (29), each with an outer panel edge (30, 31). The insulating shell (29) is supported radially on the jacket (16) with a shell edge (33). An insulating gap (35) is formed radially between the jacket and the insulating shell.

摘要： A muffler for mounting to a handheld pneumatic tool, such as a die grinder. The muffler comprises a hollow open-ended casing having an inner wall lined with a thick layer of an insulating material. The muffler is sleeve mounted about a coupler positioned between an exhaust end of the pneumatic tool and an air adapter supplying compressed air to the pneumatic tool for operation thereof. A plate comprising a plurality of perforations is positioned at a first face of the casing adjacent the air adapter. A biasing member is further placed between the plate and the air adapter for biasing a second face of the casing against the exhaust end. In this manner, during operation of the pneumatic tool, released air expelled at the exhaust end is directed through the casing to reduce a level of the noise at the exhaust end.
