Patent ID: 8740590

Claim:
An apparatus comprising: a gas compressor system, the gas compressor system having one or more cylinders fluidly connected to suction piping at an input side and discharge piping at an output side, gas flowing through interior passageways defined by the suction and discharge piping; a side branch absorber connected to the suction or discharge piping for reducing gas pulsations associated with the gas compressor system; the side branch absorber comprising a Helmholtz resonator and therefor having a volume housing defining an interior space filled with a fluid which acts as a spring, and having a relatively narrow inlet reducer filled with the fluid which acts as a mass attached to the spring; the inlet reducer extending from the suction or discharge piping to the volume housing; and a hyperbolic horn internal to the volume housing, the horn having a large diameter at a first end and tapering to a smaller diameter near a second end, the horn first end attached to the inlet reducer, the horn increasing a mass reactance of the side branch absorber.
