Abstract: An exemplary method includes using a pressure supply device (PSD) to actuate a hydraulic customer includes activating, when in the first position, a first gas generator of the multiple gas generators thereby driving the piston to the second position, pressurizing the hydraulic fluid, and discharging the pressurized hydraulic fluid to the customer; actuating the customer in response to receiving the pressurized hydraulic fluid; resetting the piston to first position by transferring a resetting hydraulic fluid into the reservoir; and exhausting gas and condensate from the gas chamber in response to resetting the piston to the first position.
