Abstract:
1. A turbine generator regenerative braking system for braking a rotating shaft, said braking system comprising: a rotating shaft of a piece of machinery; at least one hydraulic fluid pump operatively connected to said rotating shaft so that said rotating shaft powers the at least one pump; a hydraulic fluid circuit having one end in fluid communication with the at least one hydraulic pump and a second end comprising an adjustable-outlet jet nozzle; an hydraulic fluid turbine generator positioned near said jet nozzle and having an electrical power output; wherein the at least one hydraulic fluid pump supplies hydraulic fluid to the jet nozzle so that the jet nozzle sprays hydraulic fluid on a turbine portion of the turbine generator to generate electricity; wherein said turbine portion comprises multiple stages and said jet nozzle is moveable to spray different of said multiple stages; and wherein said rotating shaft is slowed by powering said at least one pump.
