Abstract
A muffler may comprise a casing having an internal volume, an inlet and an outlet, and a diverter plate dividing the internal volume into a first chamber and a second chamber. The diverter plate may comprise a baffle wall portion and at least one diverter having a deflecting surface oriented at an angle to the baffle wall portion. The baffle wall includes at least one aperture allowing fluid communication between the first chamber and the second chamber. The diverter is preferably suspended with respect to the casing, wherein no portion of the diverter directly contacts the casing.
Claims22
A muffler comprising:
- a casing having an internal volume, an inlet and an outlet;
- and
- a diverter plate dividing the internal volume into a first chamber and a second chamber, the diverter plate comprising a baffle wall portion, a first diverter, a second diverter and a connecting member that is separate and distinct from the baffle wall portion, the baffle wall portion having a first aperture allowing fluid communication between the first chamber and the second chamber, the first diverter having a deflecting surface oriented at a first angle to the baffle wall portion, a first portion of the connecting member attached to the first diverter and a second portion of the connecting member attached to the second diverter;
- wherein the first diverter is positioned such that exhaust gasses flowing through the first aperture are deflected against the deflecting surface.
A muffler comprising:
- a casing having an internal volume, an inlet and an outlet;
- and
- a diverter plate dividing the internal volume into a first chamber and a second chamber, the first chamber having the inlet, the second chamber having the outlet, the diverter plate comprising a first diverter, a second diverter and a baffle wall portion having at least one aperture, the first diverter and the second diverter oriented at equal but opposite angles with respect to the baffle wall portion, the at least one aperture allowing fluid communication between the first chamber and the second chamber;
- wherein the first diverter and the second diverter extend into the second chamber.
A method of making a muffler comprising:
- providing a casing having an internal volume;
- providing a diverter plate comprising a baffle wall portion, a first diverter, a second diverter and a connecting member that is separate and distinct from the baffle wall portion, the baffle wall portion having an aperture, each diverter having a deflecting surface oriented at an angle to the baffle wall portion, a first portion of the connecting member attached to the first diverter and a second portion of the connecting member attached to the second diverter;
- orienting the diverter plate within the internal volume of the casing such that the diverter plate divides the internal volume into a first chamber and a second chamber, the aperture allowing fluid communication between the first chamber and the second chamber;
- and
- securing the diverter plate to the casing.
