  • Methods and system for generating electrical power from a pressurized fluid source
    Patent number: 6407465
    Abstract: A pressurized fluid system provides electrical power to a load and includes a fluid motor, a generator, an energy storage device and a controller. The system supplies fluid to the fluid motor, which provides a generator with power producing a voltage used to supply power to a load and provide energy to the energy storage device. The controller selects which of various sources within the system provides fluid to the fluid motor based on the operating mode of the system. When fluid supplied to the fluid motor is discontinued, the energy storage device discharges providing power to the load.
