ABSTRACT:
A muffler for reducing the sounds of combustion gases exhausted from an internal combustion engine including an elongated fluid passage extending between an inlet and an outlet such that the outlet is in fluid communication with the inlet. Further, the inlet being connectable with the gases exhausted from the engine and the outlet being connectable with the atmosphere. The muffler further including an outer tank surrounding the passage and a tubular connector having a first end in fluid connection with the passage and a second end in fluid connection with the tank such that the connector produces a fluid connection between the passage and the tank. The connectors having a perforated resistance plate to restrict the fluid flow between said passage and said sound chamber thereby reducing the severity of the sound or fluid pulses entering and exiting said sound chamber, perforations in said perforated plate forming an open portion of said plate and said open portion being less than 60 percent.
