Definitions

  • the present disclosure generally relates pressure regulators, and more specifically to magneto strictive actuated pressure regulators.
  • Aircraft survival systems such as passenger emergency evacuation and the life support oxygen systems, use the stored pressurized gas in pressurized cylinders. There is a preference for extended service life of the pressurized gas cylinder with low maintenance effort and cost.
  • the pressurized gas cylinders use valve modules that are directly assembled to the pressurized gas cylinder that include provisions for filling the gas cylinder, preserving the filled gas cylinder, and discharging the pressurized gas.
  • the valve modules are connected to the pressurized gas cylinder using a threaded interface and static seals at the interface.
  • the interface seals and the valve internal seals are prone to have minute leakage causing loss of gas from the cylinder over time.
  • the current storage system is periodically overhauled and the gas filled to desired levels. This involves considerable maintenance efforts with additional cost for each aircraft and across a fleet of aircraft.

  • an actuator for use with a pressurized gas bottle that prevents pressurized gas within the gas bottle from leaking out of the gas bottle.
  • the actuator is coupled to the gas bottle to prevent pressurized gas from being released from the gas bottle.
  • the actuator is coupled to the gas bottle enabling the gas bottle to be refilled and/or pressurized after releasing the pressurized air from the gas bottle.
  • the actuator includes a solenoid, a magneto strictive material, and a drive rod to maintain the seal of the pressurized gas bottle and to open the pressurized gas bottle.
  • the drive rod extends through the magneto strictive material and into the actuator.
  • the solenoid surrounds the magneto strictive material.
  • the drive rod may be further coupled to a lifter and/or sleeve to provide a downward pressure on a fracture disk welded to an opening of the gas bottle. A downward pressure from the lifter and/or sleeve may provide an equalizing force to an upward pressure from the pressurized gas. In various embodiments, this equalizing force prevents the pressurized gas from leaking out the gas bottle.
  • the solenoid is energized by a DC power source.
  • the solenoid generates a magnetic field in response to being energized by the DC power source.
  • the magnetic field aligns the molecules of the magneto strictive material, causing the magneto strictive material to stretch, or elongate.
  • the actuator prevents the magneto strictive material from elongating in a downward direction, therefore the magneto strictive material elongates in an upward direction.
  • the elongation of the magneto strictive material provides an upward force on the drive rod, causing the drive rod to move upward, thereby releasing the downward force on the gas bottle, and more specifically, on the fracture disk.
  • the pressurized gas in the gas bottle ruptures the fracture disk in response to the downward force of the drive rod being removed.
  • lifter and/or sleeve are forced upward by the pressurized gas leaving the gas bottle.
  • the pressurized gas may exit the actuator through an opening in the actuator.
  • the solenoid may be energized for a short period of time such as for about 0.5 seconds to about 1 second.
  • the lifter and/or sleeve may further include a locking mechanism to lock the actuator in an open position to allow the pressurized gas to exit the gas bottle.
  • System 100 includes a gas bottle 102 having a fill valve 104 located in the bottom region (e.g., the negative y-direction), a neck 106 including an opening 108 in the top region (e.g., the y-direction), and a fracture disk 110.
  • Fill valve 104 may be welded to gas bottle 102 and be in an open state prior to filling gas bottle 102. After filling gas bottle 102 becomes pressurized, closing fill valve 104 and sealing gas bottle 102.
  • Fracture disk 110 may be welded within neck 106, and more specifically within opening 108, to prevent the pressurized gas from exiting gas bottle 102.
  • Gas bottle 102 filled and pressurized with gas may be referred to as a hermetically sealed type of gas bottle.
  • Fracture disk 110 may be a thin metallic disk that is either cold welded or fusion welded directly or indirectly to gas bottle 102.
  • Gas bottle 102 is then filled to desired pressure level using fill valve 104.
  • Fill valve 104 is then sealed closed, achieving a hermetically sealed gas bottle 102. It is understood that there may be other ways to achieve a hermetically sealed pressurized gas bottle.
  • An actuator 112 is connected to neck 106 of gas bottle 102.
  • Actuator 112 includes an actuator body 114, including an outlet 116, and a drive rod assembly 118 for activating actuator body 114.
  • actuator 112 may be threaded and screw onto neck 106 of gas bottle 102.
  • actuator 112 may be welded to neck 106 of gas bottle 102.
  • Drive rod assembly 118 activates actuator body 114 in response to an electric charge. Actuator body 114 breaks fracture disk 110 allowing the pressurized gas in gas bottle 102 to exit through neck 106, and more specifically opening 108, and through outlet 116.
  • Actuator 200 may be an example of actuator 112 described above with respect to FIG. 1 .
  • Actuator 200 includes a drive body 202, a drive rod 204, a solenoid 206, a magneto strictive material 208, leads 210, a spring 212, an actuator body 214, a lifter 216, and a sleeve 218.
  • Actuator body 214 further includes a first cavity recess 220 and a second cavity recess 222.
  • Sleeve 218 further includes metallic balls 224 configured to lock into first cavity recess 220 or second cavity recess 222.
  • Drive body 202 houses solenoid 206, magneto strictive material 208, and a top portion of drive rod 204 (e.g., the y-direction).
  • Magneto strictive material 208 surrounds the top portion of drive rod 204 and includes a hole through which drive rod 204 passes.
  • the top portion of drive rod 204 may have a flared portion 226 to prevent drive rod 204 from passing completely through magneto strictive material 208 (e.g., in the negative y-direction).
  • a bottom portion of drive rod 204 (e.g., the negative y-direction) has a threaded interface 228. Threaded interface 228 of drive rod 204 connects to lifter 216.
  • actuator 200 As illustrated in FIG. 2A , actuator 200, and more specifically lifter 216 and sleeve 218, is in a down, or closed state.
  • a bottom portion of sleeve 218 e.g., the negative y-direction
  • metallic balls 224 are locked into first cavity recess 220, and spring 212 is elongated, providing a downward force (e.g., in the negative y-direction) onto lifter 216 and sleeve 218.
  • a bottom portion of lifter 216 exerts a downward force (e.g., in the negative y-direction) on sleeve 218, keeping sleeve 218 adjacent to fracture disk 110.
  • Pressurized gas within gas bottle 102 exerts an upward (e.g., in the y-direction) force on fracture disk 110.
  • the force of sleeve 218 against fracture disk 110 balances the force of the pressurized gas within gas bottle 102.
  • Leads 210 are connected to a power supply and provide power to solenoid 206.
  • a magnetic field is generated by solenoid 206 in response to power being provided by leads 210.
  • the magnetic field causes magneto strictive material 208 to elongate linearly (e.g., in the y-axis), as illustrated in FIG. 2B .
  • a bottom portion of magneto strictive material 208 is supported by drive body 202 and restricts movement of magneto strictive material 208, therefore magneto strictive material 208 elongates and extends in an upward direction (e.g., the y-direction) away from drive body 202.
  • the elongation of magneto strictive material 208 provides a pushing force on drive rod 204, and more specifically, on flared portion 226 of drive rod 204, causing drive rod 204 to translate upward (e.g., in the y-direction).
  • the upward translation of drive rod 204 pulls lifter 216 upward (e.g., in the y-direction) due to drive rod 204 and lifter 216 being connected by threaded interface 228.
  • the upward translation of lifter 216 compresses spring 212.
  • the movement of lifter 216 releases metallic balls 224, allowing metallic balls 224 to move radially inward and out first cavity recess 220.
  • the downward force (e.g., the negative y-direction) provided by sleeve 218 onto fracture disk 110 is removed in response to the bottom portion of lifter 216 disengaging from sleeve 218.
  • the upward force (e.g., the y-direction) of the pressurized gas within gas bottle 102 ruptures fracture disk 110, forcing sleeve 218 upward (e.g., the y-direction) and locks metallic balls 224 into second cavity recess 222, as illustrated in FIG. 2B .
  • the pressurized gas in gas bottle 102 exits gas bottle 102, through actuator body 214, and out through an outlet 230.
  • outlet 230 may be coupled to a tube, hose, or other member to further direct the pressurized gas.
  • Solenoid 206 may be de-energized, returning magneto strictive material 208 to its original form while sleeve 218 remains in an open state due to metallic balls 224 being locked in second cavity recess 222.
  • magneto strictive material 208 may be a terbium-dysprosium-iron alloy, such as the alloy known in the industry as Terfenol-D. In various embodiments, magneto strictive material 208 may be a nickel-manganese-gallium alloy. In various embodiments, magneto strictive material 208 may have a stretch performance of about 0.5% to about 8%, or about 1% to about 1.5% for some alloys and about 5% to about 6% for other alloys. That is, magneto strictive material 208 elongates to a length about 0.5% to about 8% longer than its initial state in response to a magnetic field.
  • Actuator 300 may be an example of actuator 112 described above with respect to FIG. 1 .
  • Actuator 300 includes similar components to actuator 200 described above with respect to FIGS. 2A and 2B , including a drive body 302, a drive rod 304, a solenoid 306, a magneto strictive material 308, leads 310, a spring 312, an actuator body 314, a lifter 316, and a sleeve 318.
  • Actuator body 314 further includes a first cavity recess 320 and a second cavity recess 322.
  • Sleeve 318 further includes metallic balls 324 configured to lock into first cavity recess 320 or second cavity recess 322.
  • actuator 300 further includes a fill valve 350 and a cavity 352 for housing a pressure regulator.
  • gas bottle 102 may be filled using fill valve 350.
  • actuator 300 is in a closed, or down, state, as described above with respect to FIG. 2A .
  • actuator 300 maintains a pressure equilibrium between pressurized gas in gas bottle 102 and sleeve 318 of actuator 300.
  • This pressure equilibrium allows pressurized gas to be stored in gas bottle 102 with little to no gas leaking from gas bottle 102.
  • Leads 310 provide power to solenoid 306.
  • Solenoid 306 generates a magnetic field in response to being energized by power received through leads 310.
  • Magneto strictive material 308 elongates, extending upward (e.g., in the y-direction) in response to the magnetic field generated by solenoid 306, as illustrated in FIG. 3B .
  • magneto strictive material 308 As magneto strictive material 308 elongates, it exerts an upward force (e.g., the y-direction) on drive rod 304 which in turn exerts an upward force on lifter 316 causing lifter 316 to move upward.
  • the pressure equilibrium is disrupted by lifter 316 move upward (e.g., the y-direction).
  • the force exerted on fracture disk 110 by the pressurized gas in gas bottle 102 causes fracture disk 110 to break, or rupture.
  • the pressurized gas forces sleeve 318 upward (e.g., the y-direction) causing metallic balls 324 to move from first cavity recess 320, as illustrated in FIG. 2A , and to lock in place in second cavity recess 322, as illustrated in FIG. 2B .
  • the pressurized air in gas bottle 102 can exit gas bottle 102 through actuator 300 and out through the pressure regulator in cavity 352.
