Abstract

A muffler assembly, for use in the exhaust systems of vehicles or machinery using internal combustion engines, particularly piston or Wankel rotary types, consisting of either a square or round(ed) tube, with perforated baffles folded at angles, affixed within it.

1 . An exhaust muffler of simplified design, comprising a tube with gang of folded, angled and perforated baffles affixed in it. The angled design of the baffles allowing more surface area to be exposed to the cross-sectional area of the tube, such that they do not represent an appreciable resistance.  
     
     
         2 . Folded angled baffles in  claim 1 , in which the perforations are flanged slots, allowing the pulsations of gas traveling through them to be aimed.  
     
     
         3 . Folded angled baffles in  claim 1 , in which they are modular, such that once a size and shape is determined for a given tube, the same dimensions may be used for all the baffles used in that tube.  
     
     
         4 . Folded angled baffles in  claim 1 , in which their orientation can be rotated, in relation to each other, such that the flow of gasses through them may swirl in conjunction with the rotation of orientation.  
     
     
         5 . Folded angled baffles in  claim 1 , in which they may be used in differing numbers, spacings and orientations, to allow flexibility within the design, to allow use for a wide range of applications.  
     
     
         6 . The tube in  claim 1 , which may not deviate greatly from the overall size of the exhaust system, allowing flexiblity in placement, within the undercarriage of an automobile, for example.  
     
     
         7 . The tube in  claim 1 , which may be square or round in cross-section, or any range of shapes that allow the use of the folded angled baffles, such that the resulting design flexibility is a benefit to the designers of the overall exhaust system.
