Pulsation Dampening Apparatus

Abstract: 

This invention relates to improved acoustic filters of the general type employed to dampened pulsations in a flowing fluid stream such as those created by a compressor, a blower, internal combustion engine, and the like. In one of its aspects, it relates to such a filter in which the transmission of resonant frequencies between the filter components is reduced. In still another of its aspects, it relates to such a filter in which certain modes of resonant vibration are discouraged or dampened.
