Multiple Gas Generator Driven Pressure Supply

摘要

A pressure supply device in accordance to one or more aspects includes an elongated body having an internal bore extending from a power end to a discharge end having a discharge port, two or more gas generators connected to the power end and a hydraulic fluid disposed in the bore between a piston and the discharge end. The ignition of one of the gas generators drives the piston to exhaust a partial volume of the hydraulic fluid that is less than the total operational volume of the hydraulic fluid under pressure to operate at a connected device.

1. A pressure supply device, comprising:
an elongated body having an internal bore extending from a power end to a discharge end having a discharge port; a first gas generator and a second gas generator connected to the power end; a piston movably disposed in the internal bore; and a hydraulic fluid disposed in the internal bore between the piston and the discharge end, wherein a portion of the hydraulic fluid is exhausted under pressure through the discharge port in response to actuation of one or more of the first and the second gas generators.
