Abstract: An improved thermal relief vent for a fuel tank, and a method of manufacturing the same, includes a thermal relief ring that is used to create a mechanical seal within the vent. The thermal relief ring, at room temperature, is crimped in place by use of the vent cap itself. The crimped thermal relief ring creates a mechanical seal between the vent and the vent cap, up until a predetermined thermal relief point, at which time the thermal relief ring will soften and/or yield and release the vent cap from the vent body.

Abstract: An apparatus and method for rapid fluid venting that includes a burst seal disposed in a venting aperture. The burst seal seals the venting aperture so that fluid flow therethrough is not enabled. A piston defining at least one piston aperture therethrough, the piston being movably disposed proximate the burst seal. At least one actuator, actuatable between a first configuration and a second configuration. The actuator is engaged with the piston such that when the actuator actuates from the first configuration to the second configuration, the actuator impels the piston so that the piston ruptures the burst seal. With the burst seal ruptured, the piston aperture and the venting aperture are in communication so as to enable fluid flow through the venting aperture and the piston aperture.

Abstract: A thermally activated relief valve is used with a compressed gas storage cylinder. A valve body has a passage for communication with the interior of the cylinder. A metal disc sealing the passage has a first side exposed to the interior of the cylinder and a second side opposite the first side. A cutting end of a movable hollow bayonet is positioned in the passage of the valve body adjacent to the second side of the metal disc. A spring biases the bayonet toward the metal disc. A thermal trigger is operably coupled to the bayonet for holding the bayonet in spaced relation to the metal disc until the thermal trigger reaches a predetermined temperature threshold. Upon reaching the predetermined temperature threshold, the thermal trigger releases the bayonet thereby allowing the cutting end of the hollow bayonet to move toward the metal disc under force exerted by the spring to pierce the metal disc and thereby expose a flow path through the hollow bayonet. A portion of a wall of the bayonet, adjacent to the cutting end, is removed to prevent any potential remaining flap of the metal disc from wedging inside the hollow bayonet and blocking the flow path through the hollow bayonet.

Abstract: A non-reclosing overpressure protection device such as a rupture disc provides a non-reclosing opening upon forcible contact with a knife blade. A bellows, having an inlet capable of being sealably connected to a source of pressure (the vacuum system) and an outlet containing the rupture disc, transmits the pressure in the system to the disc. The bellows maintains the disc away from the knife when the pressure is below an overpressure amount, and carries the disc to a position when the pressure is above an overpressure amount where the disc is ruptured by the knife.

Abstract: A thermally activated pressure relief valve includes a valve housing with an inlet communicating with an interior of a pressure vessel, and a passage from the inlet, through the housing, to an outlet for communicating with the exterior of the housing. A seal plug is disposed within a cavity of the housing and across the passage for sealing the passage. A thermal trigger engages the seal plug within the cavity to restrict movement of the seal plug and maintain a seal of the passage when a temperature adjacent to the housing is below a predetermined temperature threshold. The thermal trigger releases the seal plug, which is movable within the cavity, allowing the seal plug to relocate within the cavity when the temperature reaches the predetermined temperature threshold, thereby exposing a flow path between the inlet and outlet through which gas can escape.

Abstract: A thermally activated relief valve is used with a compressed gas storage cylinder. A valve body has a passage for communication with the interior of the cylinder. A metal diaphragm sealing the passage has a first side exposed to the interior of the cylinder and a second side opposite the first side. A hollow bayonet is mounted to the valve body on the second side of the diaphragm. A spring is used to bias the bayonet toward the diaphragm. A thermal trigger is operably coupled to the bayonet for holding the bayonet in spaced relation to the diaphragm until the thermal trigger reaches a predetermined temperature threshold. Upon reaching the predetermined temperature threshold, the thermal trigger releases the bayonet so that the bayonet moves toward the diaphragm under force exerted by the spring and so that the bayonet pierces the diaphragm.

Abstract: To vent the contents of a pressure vessel upon failure of the vessel due to overheating or to abnormal pressure increase therein, a safety valve defines two passages through it both leading from the vessel interior to atmosphere. One passage is normally obstructed by a fusible member; the other is normally obstructed by a rupturable disc or like member.

Abstract: A burst disc unit for safety relief use in a fuel tank, responsive to temperature, and bursting at a predetermined temperature. It includes a housing with a disc element sealed thereon, and eutectic material in the housing supporting the disc element. Also knife blades are provided in the housing. Upon the predetermined temperature being reached, the eutectic material melts and runs out and the fuel in the tank forces the disc element against the knife blades and bursts, or cuts, or breaks it and the fuel runs out.

Abstract: An improved frangible disc valve which may be operated manually by explosive charge, by gaseous or hydraulic pressure, by the release of a compressed spring, by a solenoid, or by any conventional method of creating a rotary motion. The valve includes a frangible fitting made of a single piece of metal so as to be leakproof. When the valve is opened, a metal disc is sheared and carried away from the fitting by the piston. An unobstructed passageway in the piston is then placed in line with the valve inlet and outlet allowing free access to the discharge of the controlled medium; the controlled medium being either liquid, a gas, or a semisolid. A pilot rod extends from the operating piston through a guide hole to insure proper alignment, and also provides a positive indication of the open or closed condition of the valve. Simultaneously, a detent piece is driven into a cavity in the piston by a compressed spring. This action locks the piston into the fully open position and retains the hollow cylinder in axial alignment. Alternatively, an external nut can be operated to break the frangible portion, after which a compressed spring completes the operation to carry the piston to the locked open position.
