Firearm suppressor

Abstract

The suppressor uses an elastic outer housing or sleeve that temporarily expands and contracts under the pressure impulse of the propellant gases to help reduce the sound signature of the report. During discharge, the elastic housing or sleeve expands beyond its relaxed normal shape, but quickly contracts and returns to its original shape and dimension. The expansion of the elastic housings and sleeves temporarily increases the internal volume of the suppressor providing a mechanical control of the internal pressure reduction and sound attenuation without the need for increased suppressor dimensions.

I claim: 
     
         1 . A suppressor for a firearm having a barrel, the suppressor comprising:
 a suppressor body mountable to the firearm barrel for receiving a discharged round therethrough, the suppressor body having a suppressor interior thereof, the suppressor body having a first suppressor end mountable to the firearm barrel and a second suppressor end opposite the first suppressor end through which the round and discharge gases exit the suppressor,   the suppressor body constructed in part of an elastic material that allows the suppressor housing to temporarily expand and contract during the discharge of the firearm such that the volume of the housing interior increases and decrease under the influence of pressure within the housing interior.   
     
     
         2 . The suppressor of  claim 1  wherein the suppressor body includes an elongated rigid tubular housing having at least one vent opening therein between the first suppressor end and the second suppressor end, and a elastic sleeve mounted over the housing between the first suppressor end and the second suppressor end. 
     
     
         3 . The suppressor of  claim 2  wherein the sleeve expands outward from the housing during the discharge of the firearm. 
     
     
         4 . The suppressor of  claim 2  wherein the suppressor body includes a pair of clamps holding the sleeve to the housing.
