ABSTRACT:
Apparatus and method for selectively determining the resonant frequency of a gas compressor including a compressor drive motor and a muffler in a generally spaced relationship, and an apparatus mechanically linking the compressor drive motor and the muffler. The apparatus as disclosed in one embodiment includes two conical frustums as wedge members, each having an axial bore accommodating a single non-resilient shaft for joining the conical frustums such that the shaft may be adjusted to force the wedge members closer together, biasing the muffler with respect to the compressor drive motor, and thereby adjusting the resonant frequency of the compressor structure to a determined resonant frequency.
