Energy conversion system using windmill

Claim 2

An energy transfer system comprising: a rotatable windmill responsive to atmospheric wind; an air compressor coupled to the windmill for compressing air as a function of the rotation thereof under the influence of atmospheric wind; means coupled with the compressor for storing air compressed thereby; a prime mover including a piston and cylinder assembly, said piston of the assembly having a control rod responsive to a fluid under pressure, there being a rack on the control rod, and structure coupled to the rack for connecting the same to a workproducing apparatus; a hydraulic motor having a pair of tanks containing a liquid, said tanks being coupled to said prime mover for supplying liquid thereto to thereby actuate said control rod and to maintain it in operation in response to a change in the level of the liquid in said tanks to thereby permit said prime mover to operate said work-producing apparatus, said storing means being in fluid communication with said tanks to supply compressed air thereto for changing said liquid level therein; and a valve responsive to the operation of the prime mover for controlling the flow of compressed air from said storing means into and out of each tank, respectively.

Claim 3

An energy transfer system comprising: a rotatable windmill responsive to atmospheric wind; an air compressor coupled to the windmill for compressing air as a function of the rotation thereof under the influence of atmospheric wind; a tank coupled with the compressor for storing air compressed thereto; an intensifier coupled to the tank for compressing air thereinto as a function of the operation of said air compressor; a prime mover having actuatable means responsive to hydraulic fluid under pressure for operating a work-producing apparatus; a hydraulic motor having tank means containing a hydraulic fluid, said tank means being coupled to said prime mover for supplying hydraulic fluid thereto to thereby actuate said operating means and to maintain it in operation in response to a change in the level of the hydraulic fluid in said tank means to thereby permit said operating means to operate a work-producing apparatus, said storing means being in fluid communication with said tank means to supply compressed air thereto for changing said hydraulic fluid level therein; and valve means responsive to the operation of the prime mover for controlling the flow of compressed air from said storing means to said tank means.

Claim 4

An energy transfer system comprising: a rotatable windmill responsive to atmospheric wind; an air compressor coupled to the windmill for compressing air as a function of the rotation thereof under the influence of atmospheric wind; a tank coupled with the compressor for storing air compressed thereto; an intensifier coupled to the tank for compressing air thereinto as a function of the operation of said air compressor; a prime mover having actuatable means responsive to hydraulic fluid under pressure for operating a work-producing apparatus; a hydraulic motor having tank means containing a hydraulic fluid, said tank means being coupled to said prime mover for supplying hydraulic fluid thereto to thereby actuate said operating means and to maintain it in operation in response to a change in the level of the hydraulic fluid in said tank means to thereby permit said operating means to operate a work-producing apparatus, said storing means being in fluid communication with said tank means to supply compressed air thereto for changing said hydraulic fluid level therein; and valve means responsive to the operation of the prime mover for controlling the flow of compressed air from said storing means to said tank means.
