摘要： A straight-through flow muffler (10) is shown. A cylindrical housing (11) has an inlet (13a), an outlet (14a), and a pair of axially aligned, longitudinally spaced tubes (15, 16) extending from the inlet and outlet into the center of the muffler housing. Imperforate baffles (17, 18) separate the muffler housing into a plurality of attentuation chambers (20, 21, 22) surrounding the tubes (15, 16). A pair of sonic chokes (25, 26) are mounted in series in the tubes. The baffles and a pattern of perforations in the tubes cooperate to block flow between chambers except through the sonic chokes (25, 26) while permitting fluid communication between the tubes and the individual chambers.

摘要： An exhaust muffler comprising an outer body having open ends which are enclosed by heads. An exhaust gas inlet tube is mounted in an opening in one head, while an outlet tube is mounted in an opening in the opposite end. The adjacent ends of the inlet and outlet tubes are spaced apart within the body. A baffle is secured to the inner end of the inlet tube, closing off the tube, and the peripheral edge of the baffle is spaced from the body to provide an annular passage. Exhaust gas and sound energy entering the inlet pipe are directed outwardly by the baffle through perforations in the tube, and the gas then passes through the annular passage and is discharged from the body through the outlet tube.

摘要： A muffler (10) for reducing the noise level of gases passing therethrough is disclosed. The muffler (10) includes a housing (12) including a longitudinally extending wall (14) and a pair of opposite end walls (16, 18). Baffle plates (32, 38, 42) divide the interior space of the housing (12) into a Helmholtz resonator chamber (34), a flow chamber (36), an inlet broad band attenuator chamber (40) and an outlet broad band attenuator chamber (44). An inlet tube (20) extends through an inlet port (21) in the end wall (16), through a hole (48) in the baffle plate (38) and through a hole (50) in the baffle plate (32). An outlet tube (22) passes through an outlet port (23) in the end wall (18), through a hole (52) in the baffle plate (42) and through a hole (54) in the baffle plate (32). Exhaust gases enter the muffler (10 ) through the inlet tube (20), pass through holes (62) into the flow chamber (36) and exit the muffler (10) through the outlet tube (22). Broad band attenuation of noise being carried by the exhaust gases occurs in the inlet and outlet attenuation chambers (40, 44) and in a nozzle member (80). Narrow band noise attenuation occurs in the Helmholtz resonator chamber (34).

摘要： A muffler and spark arrester for use on an internal combustion engine has an outer tube extending along an axis between an inlet and an outlet. A perforate inner tube is disposed coaxially within the outer tube and merges therewith adjacent the inlet and is in effect connected thereto near the outlet by a partially toroidal end wall. Sound absorbing material is lodged between the inner and outer tubes. A plurality of nested, partially toroidal cups is disposed coaxially adjacent the end wall. A resonator-arrester chamber is coaxially nested with the toroidal cups. A central tube is held by a gas barrier wall coaxially within a portion of the inner tube. The parts are held together by an axially extending through bolt.

摘要： A vehicle exhaust system is disclosed in which a soundattenuating device in the form of a quarter-wave tuner is incorporated within an exhaust gas pipe. A partition of sheetlike construction extends axially of the pipe over a predetermined length and extends transversely from wall to wall with its opposite edges in contact therewith to separate the space into first and second portions. In the tuner structure the length is approximately equal to one-fourth of the wavelength of the sound energy to be attenuated and the upstream end of the partition is located at a pressure point corresponding to the wavelength to be attenuated and the downstream end of the partition is closed. The pipe is formed with protuberances on the internal surface such as would result from indentations of the wall and the protuberances are arranged along the length of the pipe to retain the sheetlike partition in place in engagement with the wall of the pipe. This construction permits the location of the partition in an exhaust gas pipe to form a sound-attenuating structure in either a straight or curved section of the pipe so that the pipe and the attenuating structure may be fit into the available space under the vehicle body.
摘要翻译：公开了一种车辆排气系统，其中四分之一波长调谐器形式的声衰减装置并入排气管内。板状构造的隔板在预定长度上沿管道轴向延伸，并且横向地从壁延伸至壁，其相对边缘与其接触，以将空间分离成第一和第二部分。在调谐器结构中，长度近似等于要衰减的声能的波长的四分之一，并且隔板的上游端位于与要衰减的波长相对应的压力点处，并且隔板的下游端关闭了。管道在内表面上形成有突起，例如由壁的凹陷引起的，并且突起沿着管的长度布置，以将片状分隔件保持在与管壁接合的位置。这种结构允许隔板在排气管中的位置在管的直管或弯曲部分中形成声音衰减结构，使得管和衰减结构可以装配在车体下的可用空间中。

摘要： Sound and resonance apparatus for systems engaged in dissipating gases under varying temperature, pressure and velocity conditions. The present invention is directed to control systems adapted to muffle and/or silence the explosive sound of gas emulsion under elevated temperature, pressure and high velocities as in exhaust gases emitted from various engines such as combustion engines, industrial tubular structures, firearms and the like by directing said gas into a muffler device or system having a concave end of a helicoidally formed body by casting or provided by a strip wound into a number of helicoidal cones; namely, and helicoidal cones having their transverse surfaces inclined, pitched or sloped at an angle within controlled limits to the axis of the helicoid and distance between the base and apex of each of said helicoid cones; namely, the frustums, by which is meant a spatially formed helicoidal cone being within prescribed spaced limits in order to effect maximum efficient as to resonance and sound control and the beneficial utilization of the exhaust gases to do work.
