Configuring a high-vapor-pressure (HVP) material comprising a plurality of component hydrocarbons; flashing the HVP material from an HVP liquid to an HVP vapor as the HVP liquid is introduced into an evacuated portion of a containment vessel; introducing a relief mass from a process relief event occurring outside the containment vessel to mix with the HVP material in the containment vessel; and distributing energy from the process relief mass within the containment vessel using a plurality of energy absorption processes in the component hydrocarbons as the plurality of component hydrocarbons respectively condense to liquid phases over time. The evacuated portion of the containment vessel may be a headspace vacuum above a low-vapor-pressure (LVP) liquid within the containment vessel. The HVP material may comprise C4-C10 hydrocarbons. The HVP material may comprise a plurality of component hydrocarbons having diverse boiling points and vapor pressures, that absorb and distribute the relief mass energy.

A vehicle fueling control system according to an exemplary aspect of the present disclosure includes, among other things, a fuel inlet conduit configured to receive a fuel dispensing nozzle, and a blocking assembly. The blocking assembly is configured to move back and forth between a fill blocking position that blocks airflow through a port of the fuel dispensing nozzle and a fill permitting position that permits airflow through the port of the fuel dispensing nozzle.

The present invention relates to a system and assembly for refilling a reservoir with liquid dispensed from a dispenser, in particular, but not exclusively, to a system and assembly for the substantially leak-free refilling of the reservoir of a smoking-substitute device with a liquid comprising nicotine from a refill dispenser. The assembly is configured to provide a gas communication pathway through the assembly and physically separate from the liquid communication pathway for venting gas from an end of the assembly proximal the first aperture to an exterior of the assembly responsive to the movement of the assembly to the secured and open configuration, the assembly configured to close the gas communication pathway in the unsecured and closed configuration

A mobile fuel delivery system and method are described for dispensing fuel in a poorly ventilated area. The system includes a fuel dispensing nozzle for dispensing the fuel; a cargo tank 16 for containing the fuel; a vapour recovery nozzle for recovering vapour from a fuel tank of a vehicle during fuelling; a sealing mechanism for sealingly engaging the fuel tank, a vapour tank 18; a pressure/vacuum release valve 20 connected between tank 16 and tank 18 and which is operable to increase/decrease pressure within tank 16 during dispensing of fuel and recovery of vapour recovered by the vapour recovery nozzle and pumped into the tank 16; and a safety mechanism including a control module 38 and a pressure detector 36 for detecting pressure within the tank 18, the module 38 being operable to stop fuel dispensing when pressure in tank 18 reaches a predetermined pressure.

A fluid dispensing nozzle including a nozzle body having a fluid path and a suction path therein. The nozzle has a valve positioned in the fluid path and configured to selectively prevent or allow a flow of fluid through the fluid path, and a manually operable actuator operatively connectable to the valve. The nozzle also includes a suction generator configured to apply a suction force in the suction path at a suction location. The suction path includes an expansion chamber located upstream of the suction location with respect to a direction of flow in the suction path. A bottom surface of the expansion chamber and a bottom surface of a portion of the suction path positioned immediately upstream of the expansion chamber are generally aligned.
