The subject of the invention is a dispensing nozzle for dispensing a fluid into a tank of a motor vehicle. The dispensing nozzle comprises the following features: the dispensing nozzle comprises a channel (30) for passing through the fluid, wherein a main valve (5) is arranged in the channel (30), said main valve being movable between a closed position and an open position for controlling a fluid flow, the dispensing nozzle comprises a first maximum volumetric flow rate and a second maximum volumetric flow rate, wherein the second maximum volumetric flow rate is greater than the first,

According to the invention it is provided that the dispensing nozzle comprises an adjustable flow limiter (22) which is arranged downstream of the main valve (5) and which is configured to limit the fluid flow selectively to the first or second maximum volumetric flow rate. The dispensing nozzle also comprises an actuating device (20, 21) which is configured for interaction with a signal element (29) which is assigned to the tank of the motor vehicle and for the selective adjustment of the flow limiter (22) to the first or the second maximum volumetric flow rate. By the provision of a flow limiter which is adjustable due to an interaction with the signal element, a rapid and reliable filling of different-sized containers containing liquid is ensured in a structurally simple manner.

A hydrogen gas supply system comprises a storing unit that stores hydrogen, a communication unit that receives at least either of burden information indicative of an environmental burden exerted during manufacturing of hydrogen externally received by the storing unit and quality information indicative of quality with respect to the hydrogen externally received by the storing unit, a user interface unit that provides an output in accordance with the at least either of the burden information and the quality information with respect to the hydrogen supplied from the storing unit to the user, and a controller that controls the user interface unit based on an amount of the hydrogen received by the storing unit and the at least either of the burden information and the quality information, which is received by the communication unit.

A fleet refueling silo tank system gravity feeds fuel through hoses to fleet units without requiring pressurizing pumps. Specialized valves at the fleet unit fuel tanks prevent vapor escape and admit fuel at low, gravity fed pressures. The cylindrical silo tank includes an upper, gravity feed dispensing chamber and a lower reservoir chamber. A fuel pump doubles as means for moving fuel from the reservoir chamber to the dispensing chamber and for refilling the reservoir from fuel delivery trucks. Onboard telemetry transmits fuel consumption and flow rates wirelessly to a control center where operators monitor safety parameters in real time. Stored data may be analyzed to calculate fleet unit maintenance and service intervals. A tractor trailer hauls the silo tank horizontally on roads and highways and includes a gantry and hydraulic lifts to erect the silo tank into vertical operating position supported by a built-in platform.

A supply control apparatus includes a display information output unit configured to output display information to allow a user to recognize an identifier of a supply object and information to prompt the user to decide on the supply object when the supply object is supplied to a supply destination container and a supply control unit configured to remove a supply limit for the supply destination container of the supply object when a decision operation in which the user confirming the display information decides on the supply object is detected.

A control device for a fuel dispensing nozzle includes a main body having a handle extending upward from the top surface, and a pair of elongated hooks extending downward from the main body. Each of the hooks being oriented perpendicular to the main body and functioning to receive and engage a handle portion of a fuel dispensing nozzle. A controller having a control grip and a lever hook is slidingly and rotationally engaged with the main body.

A fuel dispensing system includes a fuel tank adapted to contain a quantity of fuel. A fuel dispenser in is fluid communication with the fuel tank via piping. A pump is operative to transfer fuel from the fuel tank to the fuel dispenser. A corrosive detection assembly operative to identify presence of a corrosive substance in the fuel is also provided. The corrosive detection assembly has at least one thermoelectric detector positioned to be in contact with fuel vapor in the fuel dispensing system, the thermoelectric detector producing a detector signal indicating presence of the corrosive substance. Electronics are in electrical communication with the thermoelectric detector, the electronics being operative to interpret the detector signal and produce an output if the corrosive substance is present. The at least one thermoelectric detector may comprises a plurality of thermoelectric detectors at different locations in the fuel dispensing system.

System, methods, and other embodiments described herein relate to controlling a fuel dispenser. In one embodiment, a method of controlling a fuel dispenser includes broadcasting a pairing signal to a vehicle, receiving, from the vehicle, a confirmation signal confirming completion of a pairing process between the fuel dispenser and the vehicle, transmitting, subsequent to the confirmation signal, a disable signal to the vehicle in response to data from one or more proximity sensors indicating that the vehicle is within a threshold range and a determination that the vehicle is refueling, and transmitting an enable signal to the vehicle in response to a determination that the vehicle is no longer refueling. The disable signal disables a moving capability of the vehicle, and the enable signal restores the moving capability of the vehicle.
