Title:
WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2018/146542
Kind Code:
A8
Abstract:
A wind mill for generating wind power, for the conversion of said wind power into electricity and for conserving gained wind power for later use, said wind mill us comprising a rotor or a propeller which is communicating with a 1st axle, for generating a turning moment for said 1st axle, said rotor or propeller is rotating in a flow of wind, further comprising a pump, which is communicating with said 1st axle, This is accomplished by said wind mill is communicating with a Motor, the last mentioned is comprising said pump which is comprising a piston-chamber combination, said combination is comprising a chamber which is bounded by an inner chamber wall, and comprising a piston in said chamber to be engagingly movable relative to said chamber wall at least between a first position and a second position of said chamber, said chamber having cross-sections of different cross-sectional area's at the first and second longitudinal positions, and at least substantially continuously differing cross-sectional area's at intermediate longitudinal positions between the first and second longitudinal positions, the cross-sectional area at said second longitudinal position being smaller than the cross-sectional area at said first longitudinal position, for pressurization of a fluid, and is communicating with said 1st axle, a pressure storage vessel is communicating with said pump, for storage of compressed fluid, and said Motor is communicating with a generator, said generator is providing electricity for the use by electric apparatus and/or the Mains. Said wind mill is further comprising a selection and controlling device, wherein said device is selecting the amount of electric power to direct use for electric apparatus and/or the Mains, and is controlling process parameters of both conversions: those of wind power into pressurized fluid, and / or pressurized fluid into electricity.
