Abstract
An automatic compression brake muffler is provided including a muffler pipe. An auxiliary pipe is connected to the muffler pipe and defines passages which are offset from the muffler pipe. Next provided is a mechanical valve having an open orientation for allowing the passage of air through the entire muffler pipe and a closed orientation for precluding the passage of air through the entire muffler pipe and further forcing air through the auxiliary pipe. Finally, a mechanism is included for transferring the mechanical valve to the closed orientation only when a compression brake is actuated.
