Abstract:
A process of making an electromechanical device utilizing a working fluid comprising the steps of:introducing a high pressure liquid or supercritical fluid into an electromechanical device utilizing or working fluid having a size no greater than about 10 microns from a source of said liquid or supercritical fluid under thermodynamic conditions consistent with the maintenance of said fluid in the liquid or supercritical state; stopping said introduction of said liquid or supercritical fluid when the pressure of said fluid in said electromechanical device equals the pressure of said liquid or supercritical fluid source; closing, concurrently with said fluid introduction stoppage, said ingress and egress into said electromechanical device; and adjusting said thermodynamic conditions to ambient wherein said working fluid in said electromechanical device is retained in the high pressure liquid or supercritical state.
