摘要： An expansion-type muffler for internal combustion engines, interposed in an exhaust system, and provided with a chamber with a substantial volume. The chamber communicates with the up-stream and down-stream sides of the exhaust system. A plate member is connected with an inner wall of the muffler body, and is provided in the body so that all of the connecting points between the plate member and the inner wall are not disposed in the same plane perpendicular to the longitudinal axis of the muffler body.

摘要： A muffler for internal combustion engines having the interior of an expansion chamber sectioned by a porous plate through which an exhaust inlet pipe is extended. The inlet pipe is closed at its down-stream end and is provided with many perforations in that part of the inlet pipe positioned in the expansion chamber. Such perforations permit the inlet pipe to communicate with the interior of the expansion chamber in the muffler.

摘要： A muffler having a sealed diffusion chamber provided at its front end with an inlet port of a cross section smaller than that of the diffusion chamber. Within the diffusion chamber there is an outlet pipe having a closed front end disposed a fixed distance from the inlet port. The rear end of the outlet pipe communicates with the atmosphere. The walls of the outlet pipe are perforated to permit communication between the diffusion chamber and the interior of the outlet pipe.
