ABSTRACT:
A fluid pressure ratio transformer which may be utilized to couple pressure variations in a working fluid operating at a given input pressure ratio to a fluid coupled load operating at a different required output pressure ratio. The device is self-modulating to pump-load, whether operating at fixed stroke or fixed frequency. The pressure ratio transformer comprises a housing and a positive displacement element within the housing dividing the housing interior into first and second chambers, each of which is filled with a compressible fluid. The working fluid in the first chamber is subjected to periodic pressure oscillations while the fluid in the second chamber is either coupled to a fluid load or may itself be the pumped fluid. The effective spring coefficients and the mass of the piston are matched to the frequency of operation so that the piston oscillates at its natural frequency. The displacement element operates as in inertial resonant compressor capable of producing the needed pressure ratio transformation (typically pressure ratio amplification) between the two chambers.
