摘要： 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.

摘要： An exemplary method of actuating an operational device includes activating a propellant in a pyrotechnic pressure generator, the pyrotechnic pressure generator comprising 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, the propellant located in a chamber between the first end and the barrier, a gas outlet orifice through the barrier providing gas communication between the chamber, and a port at the second end in communication with the operational device; producing a gas in the chamber in response to activating the propellant, the gas escaping through the gas outlet orifice into the bore and the gas applying a force to the piston; moving the piston in a stroke from a position proximate to the barrier to a position proximate to the second end; communicating a pressure to the operational device that is equal to or greater than an operating pressure of the operational device in response to moving the piston; and actuating the operational device in response to communicating the pressure to the operational device.

摘要： A slip device includes a housing forming an axial bore, an upper set of slips spaced axially above a lower set of slips, and a rack and pinion actuator radially moving the upper set of slips and the lower set of slips between a retracted position and an extended position to grip a tubular disposed in the bore. The upper set of slips and the lower set of slips can be oriented to resist downward movement of the gripped tubular and to permit upward movement of the gripped tubular. One of the upper set of slips and the lower set of slips can be oriented to resist upward movement of the gripped tubular and the other of the upper set of slips and the lower set of slips can be oriented to resist downward movement of the gripped tubular.
