ABSTRACT:
A refrigeration generation system wherein a frequency modulating mechanical resonator is positioned between a pressure wave generator and a cryocooler and serves to reduce the frequency of the oscillating gas emanating from the pressure wave generator so that it more closely comports with a more efficient operating frequency of the cryocooler.
