A variable engine muffler comprising an interior acoustic chamber and peripheral conduit elements defining a conduit through the muffler. A peripheral conduit element may be movable over a range from closed a position where the conduit is closed to the acoustic chamber and to an open position where the conduit is open to the acoustic chamber.
Claims15
An engine muffler, comprising:
- a housing;
- a chamber interior of the housing;
- an inlet for receiving engine exhaust;
- an outlet for discharging the engine exhaust;
- a conduit defining a periphery of a pathway for fluid communication between the inlet and outlet;
- said conduit comprising a first peripheral member defining a first part of the pathway periphery and a second peripheral member disposed in a first position defining a second part of the pathway periphery;
- and
- said second peripheral member movable from the first position to a second position in which said conduit and chamber are in fluid communication through a space between the first member and second member.
