Definitions

  • the present disclosure generally relates opening gas cylinders and, more specifically, to opening compressed gas cylinders.
  • Aircraft survival systems such as passenger emergency evacuation slides and life support oxygen systems use the pressurized gas stored in cylinders.
  • compressed gas cylinders use a valve module that is directly assembled to the cylinder that allows the compressed gas to exit the cylinder.
  • the valve may also be used to fill the cylinder with gas.
  • the valve is prone to leaking air from the cylinder over time.
  • the valve is generally attached to the cylinder using a threaded interface and a static seal at the threaded interface that may be prone to leaking over time.
  • regular maintenance is scheduled to overhaul and maintain the cylinder and valve including refilling the cylinder to compensate for the gas that has leaked. Maintenance may further involve replacing the static seals with new static seals. This maintenance increases the down time and cost of the compressed gas cylinders.
  • the actuator includes an actuation chamber configured to receive pressurized gas, the actuation chamber at least partially defined by a top wall and a bottom wall, a cutter body disposed within the actuation chamber between the top wall and the bottom wall, the cutter body including a top portion and a bottom portion, a cutting edge extending from the bottom portion of the cutter body, and a spring disposed between the top portion of the cutter body and the bottom wall of the actuation chamber.
  • the actuation chamber is further defined by a sidewall extending from the top wall to the bottom wall and circumferentially around the cutter body and the top portion of cutter body contacts the sidewall of the actuation chamber.
  • the actuator for opening a hermetically sealed cylinder further includes an O-ring disposed circumferentially around the top portion of the cutter body and between the top portion of the cutter body and the sidewall of the actuation chamber.
  • the actuator for opening a hermetically sealed cylinder further includes a leak vent fitting extending through the sidewall and into the actuation chamber.
  • the spring is configured to move from an uncompressed state to a compressed state in response to the cutter body moving in a first direction.
  • the cutter body moves in the first direction in response to a force exerted on the top surface of the cutter body.

  • a system including a cylinder having an opening, a fracture disk coupled to the cylinder and over the opening, and an actuator configured to break the fracture disk.
  • the actuator includes an actuation chamber configured to receive pressurized gas, the actuation chamber is partial defined by a top wall and a bottom wall, a cutter body disposed within the actuation chamber between the top wall and the bottom wall, the cutter body including a top portion and a bottom portion, a cutting edge extending from the bottom portion of the cutter body and configured to break the fracture disk in response to moving in a first direction, and a spring disposed between the top portion of the cutter body and the bottom wall of the actuation chamber.
  • the actuation chamber is further defined by a sidewall extending from the top wall to the bottom wall and circumferentially around the cutter body and the top portion of cutter body contacts the sidewall of the actuation chamber.
  • the actuator further includes an O-ring disposed circumferentially around the top portion of the cutter body and between the top portion of the cutter body and the sidewall of the actuation chamber.
  • the system further includes a pressure cartridge disposed adjacent the actuator, the pressure cartridge configured to force pressurized gas into the actuation chamber.
  • the spring is configured to move from an uncompressed state to a compressed state in response to the pressurized gas in the actuation chamber moving the cutter body in the first direction.
  • the actuator further includes a second cutting edge extending from the bottom portion of the cutter body, the second cutting edge separated from the cutting edge by a distance.
  • the cylinder holds a second pressurized gas and the actuator further includes a gas outlet to vent the second pressurized gas from the cylinder in response to the fracture disk being broken.
  • a system including a cylinder having an opening, a fracture disk coupled to the cylinder and over the opening, and an actuator configured to break the fracture disk.
  • the actuator includes an actuation chamber configured to receive pressurized gas, the actuation chamber is partial defined by a top wall and a bottom wall, a cutter body disposed within the actuation chamber between the top wall and the bottom wall, the cutter body including a top portion and a bottom portion, a central stem extending through the cutter body and contacting the fracture disk, a cutting edge extending from the bottom portion of the cutter body and configured to break the fracture disk in response to moving in a first direction, and a spring disposed between the top portion of the cutter body and the bottom wall of the actuation chamber.
  • the actuator further includes a second cutting edge extending from the bottom portion of the cutter body, wherein there is a distance between the cutting edge and the second cutting edge.
  • the central stem further extends between the cutting edge and the second cutting edge.
  • the actuator further includes a compression spring disposed between the central stem and the top wall of the actuation chamber.
  • the fracture disk further includes a notch formed in a bottom surface of the fracture disk, the notch configured to be inline with the cutting edge.
  • the cutter body is configured to move independent of the central stem.
  • references to "a,” “an” or “the” may include one or more than one and that reference to an item in the singular may also include the item in the plural. Further, all ranges may include upper and lower values and all ranges and ratio limits disclosed herein may be combined.
  • the hermetically sealed compressed gas cylinder may be filled from a port in the bottom of the cylinder or similar method.
  • the port may be designed such that the cylinder is sealed after being filled.
  • the actuation device disclosed herein uses a solenoid operated pressure cartridge to operate a cutter having a knife edge interface.
  • the cutter is assembled inside a manifold that is connected to the hermetically sealed compressed gas cylinder.
  • the cutter knife edge is initially located a distance away from the fracture disk.
  • the cutter knife edge is pushed toward the fracture disk in response to pressurized gas being released from the pressure cartridge by the solenoid. This ruptures the fracture disk and allows the gas in the hermetically sealed compressed gas cylinder to flow out.
  • the actuation device may include a stem that interfaces with the fracture disk and counteracts the bulge of the fracture disk.
  • the stem may be spring loaded.
  • metal inserts 106 may be formed of a single piece.
  • fracture disk 108 may be cold welded or fusion welded to metal inserts 106.
  • pressurized cylinder 102 is hermetically sealed.
  • pressurized cylinder 102 may be filled with pressurized gas from a bottom portion (e.g., the negative y-direction) of pressurized cylinder 102.
  • Opening 104 has a diameter d1 that may be any suitable size for a pressurized cylinder.
  • diameter d1 may be about 3 cm (about 1.18 inches) to about 30 cm (about 11.8 inches), and more specifically, about 7 cm (about 2.76 inches) to about 15 cm (about 5.91 inches). Larger and smaller values for diameter d1 are contemplated.
  • Actuation device 100 includes a pressure cartridge 110 and a manifold 112, where the manifold 112 is connected to the pressurized cylinder 102.
  • manifold 112 is threaded onto pressurized cylinder 102.
  • Pressure cartridge 110 includes a fill valve 114, a pressure cavity 116, a pressure sensor 118, a spring 120, an air gap 122, a plunger 124, a bottom wall 126 (e.g., in the negative y-direction), and an upper wall 127 (e.g., in the positive y-direction).
  • Fill valve 114 may be used to introduce air into pressure cavity 116 and pressurize the air in pressure cavity 116.
  • fill valve 114 may be a Schrader type valve.
  • fill valve 114 may be another type of valve used to fill a pressurized space, such as pressure cavity 116.
  • Pressure sensor 118 monitors the air pressure in pressure cavity 116 and provides an indication of the readiness of actuation device 100 for use.
  • pressure sensor 118 may be a microelectromechanical system (MEMS) sensor, though other types of pressure sensors are contemplated.
  • Spring 120 provides a downward force (e.g., the negative y-direction) on plunger 124, pressing plunger 124 onto bottom wall 126 thereby sealing pressure cartridge 110.
  • Air gap 122 is formed between plunger 124 and upper wall 127.
  • Cutting edges 138 are separated from one another by a distance d2.
  • distance d2 may be about 1 cm (about 0.394 inch) to about 5 cm (about 1.97 inches), and more specifically, about 2 cm (about 0.787 inch) to about 4 cm (about 1.57 inches).
  • distance d2 may be a percentage of d1 where d2 is about 10% to about 30% of d1, and more specifically, about 15% to about 20% of d1.
  • Cutting edges 138 are separated from fracture disk 108 a distance d3 (e.g., in the y-direction).
  • FIG. 1A illustrates actuation device 100, and more specifically manifold 112, in the closed position with cutting edges 138 above (e.g., in the negative y-direction) fracture disk 108 distance d3.
  • Leak vent fitting 132 vents any air leaked into actuation chamber 130 prevent actuation of cutter body 136, and more specifically, cutting edges 138.
  • FIG. 1B illustrates actuation device 100, and more specifically manifold 112, in the open position with cutting edges 138 pushed through fracture disk 108. In the open position, cutting edges 138 break through fracture disk 108 thereby opening pressurized cylinder 102.
  • distance d2 separates cutting edges 138 provides a gap between cutting edges 138 to avoid inadvertently contacting fracture disk 108'. It should be noted that as diameter d1 of pressurized cylinder 102 increases, the bulge at the center of fracture disk 108' may increase, further reducing distance d4 between fracture disk 108' and cutting edges 138.
  • FIG. 3B illustrates a fracture disk 308' including notches 310 formed therein connected to pressurized cylinder 102 in the pressurized condition.
  • the force from pressurized cylinder 102 may cause bulging, or bowing, of fracture disk 308'.
  • Notches 310 have little to no effect on the integrity of fracture disk 308' allowing fracture disk 308' to remain intact until punctured by cutting edges 138.
  • Actuation device 400 for opening a pressurized cylinder 402 is illustrated.
  • Actuation device 400 includes similar components to those described above with respect to actuation device 100 referenced in FIGS. 1A and 1B , including pressure cartridge 110 and manifold 112 and their respective corresponding components.
  • Actuation device 400 similar to actuation device 100, is connected to pressurized cylinder 402 as described above. Description of repeated components may not be repeated here.
  • Pressurized cylinder 402 has an opening 404 that is sealed by a fracture disk 408. Opening 404 has a diameter d5 that is greater than diameter d1 of opening 104. Accordingly, fracture disk 408 is larger than fracture disk 108. The increased diameter d5 of opening 404 and increased size of fracture disk 408 may result in bulging of fracture disk 408 as described above with respect to FIGS. 2B and 3B .
  • Actuation device 400 further includes a central stem 450 extending through cutter body 136 and in between cutting edges 138 to counteract any bulging that may occur in fracture disk 408.
  • Central stem 450 includes a bottom portion 450a that is in contact with an upper surface of fracture disk 408.
  • Central stem 450 further includes an upper portion 450b that is in contact with a spring 452.
  • Spring provides a downward force (e.g., in the negative y-direction) on central stem 450 causing central stem 450 to exert a downward force (e.g., in the negative y-direction) on fracture disk 408.
  • An O-ring seal 437 may be placed between central stem 450 and cutter body 136 to seal actuation chamber 130 and prevent gas from leaking through during actuation.
