Muffler for attenuating noise produced by a pneumatic device, having a conduit path for maximun noise reduction

Abstract

A muffler for attenuating noise produced by a pneumatic device. The muffler includes a housing, a base and a acoustic absorption insert. The housing defines an upstream and a downstream end, with the down stream end being closed. Further the housing defines a pathway that forces the air thru a maximum pathway thru the acoustic material. This pathway thru a directing conduit forces airflow and sound waves into the acoustic absorption material. Finally, the absorption insert material is disposed within the housing and includes a web of micro-fibers configured to absorb sound waves. This muffler can be utilized with any pneumatic devices to reduce the overall sound level of the device. with Has a reduced over all size compared to existing mufflers, and Uses a distinct design to maximize the absorption pathway. A pneumatic muffler that uses a distinct pathway to direct sound wave thru a sound absorption material.

1 . A muffler for attenuating noise produced by a pneumatic device. The muffler includes a housing, a base and a acoustic absorption insert. The housing defines an upstream and a downstream end, with the down stream end being closed. Further the housing defines a pathway that forces the air thru a maximum pathway thru the acoustic material. This pathway thru a directing conduit forces airflow and sound waves into the acoustic absorption material. Finally, the absorption insert material is disposed within the housing and includes a web of micro-fibers configured to absorb sound waves. This muffler can be utilized with any pneumatic devices to reduce the overall sound level of the device. comprising:  
   
   
       2 . A muffler of  claim 1 , where the housing defines a pathway for attenuating noise produced by a pneumatic device using a distinct conduit design to maximize the absorption pathway.  
   
   
       3 . A muffler of  claim 1  wherein the housing includes a side wall extending between the upstream and down stream end, the side wall forming a continous barrier to contain sound waves from leaving the interior of the housing.  
   
   
       4 . A muffler of  claim 1  for attenuating noise produced by a pneumatic device having reduced over all size compared to existing mufflers.  
   
   
       6 . A muffler of  claim 1  for attenuating noise produced by a pneumatic device wherein the housing and the base define a conduit the runs to approxemly 0.50 of the end of the housing.  
   
   
       7 . A muffler of  claim 1  for attenuating noise produced by a pneumatic device. The muffler includes a housing, a base and a acoustic absorption insert. The housing defines an upstream and a downstream end, with the down stream end being dosed. Further the housing defines a pathway that forces the air thru a maximun pathway thru the acoustic material. This pathway thru a directing tube forces airflow and sound waves into the acoustic absorbation material. Finally, the absorption insert material is disposed within the housing and includes a web of micro-fibers configured to absorb sound waves. This muffler can be utilizd with any pneumatic device to reduce the overall sound level of the device. comprising:  
   
   
       8 . A muffler of  claim 1  for attenuating noise produced by a pneumatic device. The muffler includes a housing, a base and a acoustic absorption insert. The housing defines an upstream and a downstream end, with the down stream end being closed. Further the housing defines a pathway that forces the air thru a maximun pathways thru the acoustic material. This pathway thru a directing tube forces airflow and sound waves into the acoustic absorbation material. Finally, the absorption insert material is disposed within the housing and includes a web of micro-fibers configured to absorb sound waves. This muffler can be utilized with any pneumatic device to reduce the overall sound level of the device.  
   
   
       9 . A muffler of  claim 1  that due to the micro-fiber nature of the absorbing material has non-icing qualities when used on a pneumatic device.
