摘要： A sound absorption device in accordance with this invention includes an enclosure loosely containing hollow beads. Preferably, the hollow beads have openings, and differ with respect to the volume of the hollow space defined by the walls of the beads, the wall thicknesses of the beads, the size of the openings of the beads and/or the number of openings on the beads. Through Helmholtz resonance, vorticity and tortuous path scattering, the beads damp sound waves over a broad range of frequencies. Preferably, the beads are formed from a material able to withstand relatively high temperatures, such as ceramic or nickel. The beads can thus be used to damp sound in applications which generate significant heat in addition to sound, such as aircraft engines, rocket motors or other loud, heat-generating sources, for example. Also, by forming the beads from a material with a relatively low thermal conductivity, the beads can also be used for thermal insulation in addition to sound absorption.

摘要： The present invention is a noise reduction apparatus for use in the exhaust system of an internal combustion engine which absorbs acoustical energy from the pressurized exhaust gases while minimizing restrictions on the exhaust gases as they flow therethrough. The relatively unrestricted exhaust gas flow provided by the present invention significantly reduces the build up of back pressure and the associated drop in power and performance of the engine. At the same time, by absorbing acoustical energy from the exhaust gases, the noise level of the exhaust system is reduced. The present noise reduction apparatus includes a housing operatively adapted for being disposed in the exhaust system of an internal combustion engine, and a plurality of generally concentric and radially spaced tubular sections disposed inside of the housing. Each tubular section is adapted with a porous wall which allows exhaust gases to flow therethrough. A plurality of sound absorbing layers are also disposed inside the housing. Each layer is operatively adapted to allow exhaust gases to flow therethrough while absorbing acoustical energy from exhaust gases coming in contact with the layer. Each layer is also operatively associated with one tubular section to allow exhaust gases to flow through the housing, from one end to the other, without having to flow through one of the sound absorbing layers.
摘要翻译：本发明是一种用于内燃机的排气系统中的降噪装置，其吸收来自加压废气的声能，同时最大限度地减少排气在流过其中时的限制。由本发明提供的相对不受限制的废气流显着地减少了背压的积累以及发动机功率和性能的相关下降。同时，通过从排气中吸收声能，减少排气系统的噪声水平。本降噪装置包括可操作地适于设置在内燃机的排气系统中的壳体和设置在壳体内部的多个大致同心且径向间隔开的管状部分。每个管状部分都具有允许废气流过其中的多孔壁。多个吸声层也设置在壳体内。每个层可操作地适于允许废气流过其中，同时从与该层接触的废气吸收声能。每个层还可操作地与一个管状部分相关联，以允许废气从一端到另一端流过壳体，而不必流过吸声层之一。

摘要： Muffler-filter apparatus for reducing both sound and particulates from exhaust gases from an engine. The apparatus includes resonating chambers, flow distribution means and a cellular ceramic core filter module. Filter regeneration mechanism includes a heating element for heating the carbon on the inlet end of the ceramic core to combustion temperature. Particulate ignition resulting in regeneration occurs when combustion air is provided. In alternate embodiments, combustion air first flows through a preheater system. A processor unit with particular logic controls the apparatus. The particular method of regeneration depends on the application in which the muffler-filter is used.

摘要： A muffler of the expansion type comprises an inlet pipe and an outlet pipe connected with each other through a main body. Minimization of pressure pulsation is achieved by a variety of means including appropriately-located apertures in those portions of the walls of said pipes within said main body, an apertured partition within said main body so located that exhaust gas passes through said partition, and appropriate tapering of said pipes. A foamed, heat-resistant material may be positioned over said apertures in said walls of said pipes. Pipe constructions suitable for mass production and pipe-to-main body constructions free of the danger of separation during prolonged use are shown.
