Patent attributes
An exemplary gas generator driven hydraulic accumulator includes an elongated body having a first end, a second end, and a bore extending axially from a barrier to the second end; a piston slidably disposed in the bore; in use a gas generator located in a chamber between the first end and the barrier; an orifice through the barrier providing fluid communication between the chamber and the bore; in use a hydraulic fluid disposed in the bore between the piston and the second end whereby the hydraulic fluid is exhausted under pressure through a discharge port in response to activation of the gas generator; and in use a one-way flow control device connected in a flow path of the discharge port to permit one-way flow of the hydraulic fluid from the bore and to block return fluid from through the discharge port into the bore.
