    摘要: The tunable resonator is coupled to the engine speed control such that the resonator is set to a different frequency range when the engine speed is changed. The frequency range is changed by opening and closing necks and/or changing the effective volume of the resonator.

    摘要: A fluid compressor includes a compressor inlet for receiving a medium, a compressor for compressing the medium, a compressor outlet for discharging the compressed medium and a compressor muffler. The compressor muffler includes a housing defining an inner space, an inlet for receiving a compressed medium, a muffling structure located in the inner space, wherein the muffling structure has a plurality of chambers for receiving the compressed medium from the inlet, an outlet for discharging the compressed medium and a flow path located in the inner space; The flow path communicates the inlet with the muffling structure and the muffling structure with the outlet; A method for reducing any noise-generating frequencies present in a compressed medium is additionally presented.
