ABSTRACT:
Resonator type mufflers of this invention utilize multiple chambers with inductor tubes between the chambers, and specific size and spatial relationships among the tubes and chambers. In one form of muffler suitable for industrial applications or vehicular use, elongated inductor tubes passing from one chamber to a second chamber have downstream ends spaced about 3/4 inch from the end wall of the second chamber, which has a central opening with area at least as large as the combined areas of the inductor tubes. For industrial mufflers which are required to be short, there is only one set of coextensively positioned inductor tubes, but for longer mufflers as on motorcycles, an elongated primary inductor preferably is used in addition, as a primary resonator stage. In another embodiment of a muffler particularly for motorcycles, first and second inductor tubes overlap within a second chamber in a particular space-saving arrangement, which also lends itself to muffler core replacement in housings of generally standard configuration.
