Muffler with acoustic absorption insert for limited clearance pneumatic device applications |
摘要 |
A muffler for attenuating noise produced by a pneumatic device having limited clearance. The muffler includes a housing, a base and an acoustic absorption insert. The housing defines an upstream end and a downstream end, with the downstream end being closed. Further, the housing tapers from a maximum width of less than approximately 1.5 inches (38 mm) to the downstream end. The base is secured to the housing at the upstream end and includes a tube for directing airflow and sound waves into the housing. Finally, the acoustic absorption insert is disposed within the housing and includes a web of fibers configured to absorb sound waves. The muffler can be utilized with a pneumatic valve having limited space available for receiving the muffler, providing noise attenuation with minimal back pressure. |
