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.
Claims20
A method, comprising:
- using a pressure supply device (PSD) to actuate a hydraulic customer, the PSD comprising a cylinder extending from a first end to a discharge end, a moveable piston disposed in the cylinder and separating a reservoir from a gas chamber, multiple gas generators in communication with the gas chamber, the hydraulic customer in communication with the reservoir, wherein in a first position the piston is located proximate to the first end and the reservoir contains hydraulic fluid, and in a second position the piston is located proximate to the discharge end, the using comprising:
- 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 via a customer flow path between the reservoir and the customer;
- resetting the piston to a first position by transferring a resetting hydraulic fluid into the reservoir via a reset flow path between the reservoir and an external fluid source comprising the resetting hydraulic fluid;
- and
- exhausting gas and condensate from the gas chamber in response to resetting the piston to the first position via a vent in communication between the gas chamber and a dump.

- actuating the customer in response to receiving the pressurized hydraulic fluid via a flow path between the reservoir and the customer;
- resetting the piston to first position by transferring a resetting hydraulic fluid into the reservoir via a reference pressure source in communication with the customer through a reset valve, wherein the resetting hydraulic fluid is the pressurized hydraulic fluid discharged to the customer;
- and
- exhausting gas and condensate from the gas chamber in response to resetting the piston to the first position via a vent in communication between the gas chamber and a dump.
