A handheld fluid meter includes a cartridge valve controlling the flow of fluid through the handheld meter. The cartridge valve includes a valve cartridge and a valve stem disposed within the valve cartridge. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The overmolded stem tip is a compliant material. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

The present invention provides a method, system and apparatus for refilling a reservoir of a smoking-substitute device with liquid from a dispenser.

An automatic shut-off fluid nozzle having a primary fluid path, a vacuum-actuated fluid shut-off assembly in the fluid path, said shut-off shutting off flow through the fluid path when the pressure chamber is subjected to a predetermined vacuum. The nozzle having a venturi port in said fluid path and connected to a vacuum channel, and a vacuum vent extending away from the vacuum channel, said vacuum vent communicating with a low vacuum environment. The nozzle further having a segregated fluid channel in the primary fluid path, the venturi port communicating with said segregated fluid channel, such that the flow of fluid past the venturi port creates a venturi vacuum in the vacuum channel. The vacuum exhausts the vacuum through the vent port when the vent port is in an open condition, and creates a vacuum in the vacuum-actuated fluid shut-off assembly when said vent port is in a closed condition.

The present disclosure is directed to a fuel tank fill pipe assembly configured to conduct liquid fuel from a fuel-dispensing nozzle to a fuel tank. The fuel tank fill pipe assembly includes a filler head assembly shaped to receive the fuel-dispensing nozzle and a filler pipe that extends from the filler head assembly toward the fuel tank. In illustrated embodiments, a coupler is included for attaching the filler head assembly to the filler pipe while blocking fuel vapor from escaping the fuel tank fill pipe assembly so that hydrocarbons present in the fuel vapor are not released into the environment.

A custom blending hose for manifold mixing of various fuels for a fuel dispensing system, including a pair of fuel dispensing hoses, generally concentrically or coaxially arranged, for passing at least a pair of fuels into a manifold assembly, for blending and intermixing of said fuels, for further delivery through a dispensing hose assembly, to a nozzle, for refueling of a vehicle. The manifold includes a housing, incorporating internally a series of apertures, through which the fuels are passed, and blended, for delivery as a uniform fuel to a vehicle during dispensing. A vapor return line may locate through the manifold.
