Embodiments described herein relate to a pressure-regulating device, systems that include the device, and related methods. For example, the pressure-regulating device may receive gas from a gas supply at a first pressure (e.g., on a supply side of the pressure-regulating device) and may regulate or reduce the pressure of the received gas to a selected or suitable second, different pressure.

An integrated pressure regulator is provided with three stages configured to reduce an extreme tank pressure down to a typical working pressure. The regulator is configured to supply a steady working pressure until the tank pressure is reduced to little more than the working pressure itself. Stages of the pressure regulator are integrated into a body and arranged to minimize regulator mass and volume. A thermally-triggered pressure relief device may be included with a triggering time adapted to enhance the safety of smaller cylinders that may be used, e.g., in aerial applications.

A pressure regulator for a hydrogen storage system, wherein the pressure regulator is adapted to operate at temperatures below −50° C., while minimizing the need for separate sealing elements and O-rings. The pressure regulator includes a main body including an inner cavity bounded by an interior wall, a piston disposed in the inner cavity, the piston including a first channel disposed adjacent a first portion, wherein the first portion is adapted to cooperate with the interior wall to form a seal between the piston and the interior wall, a first biasing device disposed in the first channel, wherein the first biasing device is adapted to exert a force on the first portion of the piston to form a seal between the first portion and the interior wall, and an end cap coupled to the main body thereby enclosing the piston to form an outlet pressure chamber.

A valve sleeve 210 includes an input port P10, an output port P21 connected to a channel for output T2, a discharge port P30 and a lead-in port P22 which is disposed to be connected to the channel for output T2. A spool 220 is provided with a second land section 224 that blocks a portion between the spool 220 and the valve sleeve 210 at a position between the output port P21 and the lead-in port P22 when the spool 220 is located in a position for connecting the channel for input T1 and the channel for output T2 and blocking a channel leading from the channel for output T2 to the channel for discharge T3, and when the spool 220 is located in a position for connecting the channel for output T2 and the channel for discharge T3 and blocking a channel leading from the channel for input T1 to the channel for output T2.

A vaporization device includes a cartridge having a reservoir that holds a vaporizable material, a heating element, and a wicking element that can draw the vaporizable material to the heating element to be vaporized. The wicking element can include two ends in contact with the reservoir. The cartridge can include an airflow control feature for controlling airflow in the cartridge.

A pressure reduction plant including two or more valve assemblies arranged in parallel and including: pressure reducers for fuel gas from the supply pressure to the delivery pressure; pilot valves to transmit a control pressure to the pressure reducers when the delivery pressure reaches the calibration value of the pilot valves; derivation conduits to transmit the delivery pressure to the pressure reducers, the pilot valves and the pressure reducer devices; command lines to transmit the control pressure from the pilot valves to the pressure reducers. One of the pilot valves is configured with a calibration value greater than the calibration value of all the remaining pilot valves and each command line is configured to communicate with a control line.

A gas filtering rubber pipe and a pressure regulating valve bank are disclosed. The pressure regulating valve bank includes an angle valve, a pressure reducing valve and the gas filtering rubber pipe including a pipe body and a filtering mechanism. The filtering mechanism includes a shell assembly and a connector arranged at a lower end of the shell assembly, the shell assembly is provided with a separation cavity and a gas outlet channel located in an upper portion of the shell assembly. The gas outlet channel can be communicated with the separation cavity. A lower end of the connector is provided with a connecting portion fixedly connected with an upper end of the pipe body, an upper end of the connector is provided with a filtering barrier. A gas outlet hole is arranged in a peripheral wall of the connector connected with the filtering barrier.

An attachable, detachable pressure reducing regulator for use with a primary high-pressure gas source, wherein the high-pressure chamber of said regulator includes a secondary gas IN portal, with a one-way valve, through which the primary container source may be refilled from an external gas source, via the high-pressure chamber of the said regulator, either independently of or concurrently during its use as a pressure reducing regulator.
