Methods and systems for on demand fuel supply
Apparatus for delivering fluid to a fluid consuming asset having a fluid tank includes a tank operable to contain the fluid and a fluid delivery coupling fluidically coupling the tank to a manifold. A pressure relief valve is fluidically coupled to the manifold, disposed between the manifold and the tank, and coupled to the tank through a recirculation inlet. The pressure relief valve is set at a predetermined pressure threshold and opens when the back-pressure in the manifold exceeds that threshold. The fluid is directed to the tank through the recirculation inlet when the pressure relief valve opens. A fluid transporting mechanism is fluidically coupled to the manifold at a first distal end and a fill cap at a second distal end. The fill cap is coupled to an opening of the fluid tank and fluid can flow from the manifold to the fluid tank through the fluid transporting mechanism.
Breakaway assembly
A breakaway assembly including a first connector and a second connector releasably coupleable to the first connector, wherein the assembly is movable between a first configuration in which the first and second connectors are releasably coupled and together define a fluid path through which fluid is flowable, and a second configuration in which the first and second connectors are not coupled together. The assembly is configured to move from the first configuration to the second configuration when a predetermined separation force is applied to the assembly. The assembly includes a closure valve positioned in one of the first or second connectors, wherein the closure valve is configured to be in an open position when the assembly is in the first configuration to allow fluid to flow therethrough, and to move to a closed position when the assembly moves to the second configuration to generally block the flow of fluid therethrough. At least part of one of the first or second connectors is axially movable relative to a remaining portion of the one of the first or second connectors, or is axially movable relative to the other one of the first or second connectors, when the assembly is in the first configuration and while the closure valve remains open, to accommodate force spikes.

Fuel dispensing device with expansion chamber
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.

DISPENSING NOZZLE
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.
