Abstract: A muffler having an inner shell of two deep-drawn inner sheet metal plates laid one atop the other and a housing shell of at least two deep-drawn outer sheet metal plates laid one atop the other. The inner shell has an encircling edge while the housing shell has an encircling housing flange with a lock seam connection which seals the housing shell. The edge of the inner shell is designed so that it barely touches the wall of the housing shell and is held in a spring-like fashion only between clamping creases of the housing shell.

Abstract: A sound attenuating muffler useful with an internal combustion engine, preferably for marine applications, contains an insert comprising an arrangement of annular sound reflecting surfaces defining an inner chamber into which engine exhaust gases flow in a first direction and one or more directors to divert the axial flow of gases and sound waves in a second direction past these sound reflecting surfaces. As the sound waves are reflected off of these surfaces back into the muffler interior, attenuation of the sound is achieved. The gases exit the muffler to the atmosphere through an outer chamber surrounding the inner chamber. A method of assembling the component parts of the insert is also described.

Abstract: A sound attenuating device is provided for attenuating noise in an exhaust system. The attenuating device includes an inlet end, an outlet end and a constricted portion therebetween. In use, the attenuating device may be disposed in a tubular housing or may be an integral portion of a tail pipe, connecting pipe, or muffler. Further, a sound suppressing system is described including one or more attenuating regions including attenuating devices. The attenuating regions are spaced to attenuate desired frequencies. Expansion chambers formed between attenuating regions contribute to sound suppression.

Abstract: An engine exhaust system for a small watercraft. The engine is fixed to a hull through a damper, while an expansion chamber is fixed directly to the hull. An exhaust port of the engine and an inlet of expansion chamber are connected by an exhaust pipe, and the inlet of expansion chamber and an outlet of exhaust pipe are connected by a fitting with thermal durability and flexibility. In the case where the expansion chamber is followed by a muffler, at least a latter half of the expansion chamber is inserted into the muffler.

Abstract: A muffler is provided comprising an array of tubes and a stamp formed external shell surrounding the tubes. The external shell is stamp formed to define at least one chamber surrounding at least portions of the tubes. The chamber extends away from peripheral portions of the external shell to define a three-dimensional volume. The chamber is characterized by a plurality of inwardly directed V-shaped grooves, with each groove extending continuously between opposed spaced apart locations on the periphery of each chamber. The grooves preferably define a parallel array of substantially identical grooves. The grooves strengthen the walls of the chamber and efficiently prevent shell noise.

Abstract: A muffler construction having improved sound attenuation characteristics. A tapered tubular metal screen is disposed within the outlet conduit of a muffler and has a axis concentric with the axis of the conduit. The screen has a closed end preferably facing in a downstream direction with respect to gas flow, and the opposite open end of the screen is attached to the conduit. The screen acts to reduce the sound levels without increasing the overall size of the muffler and with a minimum increase of weight.

Abstract: An exhaust dissipator device for a rocket exhaust has an inlet for connection to the exhaust and a plurality of smaller exhaust orifices spaced around its surface to dissipate the flow into a plurality of smaller jets. A deflector surface in the direction of exhaust flow into the container acts to further dissipate the flow and deflect it out of its original path. This may comprise an internal surface of the container, or a separate deflector plate spaced from the container surface.
