Abstract

An air intake silencer includes a box-shaped expansion chamber constructed of identically dimensioned, separable havles respectively connected to a carburetor intake system and a tubular intake member. In a basic form of the silencer, the tubular intake member includes a metal tube mounted in the expansion chamber and having a single elongate opening in communication with the interior of the chamber, the tube being connected so as to form a continuation of a hose located exteriorly of the chamber. For obtaining more effective silencing, air distribution and filtering the basic form of the silencer may be altered by dividing the expansion chamber in half with a perforated baffle plate and/or by substituting a perforated metal tube for the aforedescribed metal tube.
