An auxiliary or additive fluid for associated use with the primary diesel or related fuel, for application for reduction of exhaust pollution, and for motor or truck vehicle, or the like, includes the nozzle, the nozzle having its spout extending from its forward end, the spout having an outer sleeve, an inner sleeve through which the fluid flows during dispensing, a lower sleeve capable of shifting within the outer sleeve, and integrated with a safety valve sleeve, and biased axially inwardly of the spout when it is inserted into the fluid intake pipe of a vehicle intake for a fluid tank. A primary safety valve extends through the lower spout sleeve, and the integral safety valve sleeve is maintained in a fixed position, and normally is sealed into closure within the lower end of the lower spout sleeve. But, when the lower spout sleeve is forced axially inwardly, it unseats the safety valve from its sealing therewith, to open the spout for the dispensing of the fuel when the nozzle is actuated to allow fluid flow. In addition, a flow path for air that is normally closed by a check valve, is likewise opened, to allow for the passage of air to maintain the inoperativeness of the automatic shut-off, until such time as the fluid flow closes off the lower end said passage, initiating the automatic shut-off of the fluid dispensing nozzle, when the intake of air is blocked.

An improved method of delivering fluid to a fluid consuming asset having a fluid tank. A tank filled with fluid is coupled to a manifold through a fluid delivery coupling having a first pressure relief valve set at a first predetermined pressure threshold disposed between the tank and the manifold. The fluid is directed back to the tank through a first re-circulation inlet when the first pressure relief valve opens. A second pressure relief valve is disposed between the manifold and the tank and directs fluid back to the tank when back-pressure in the manifold exceeds a second predetermined pressure threshold. The manifold is coupled to a fluid transporting mechanism which is fluidically coupled to the fluid tank. fluid flows out of the manifold into the fluid transporting mechanism, through a fill cap and into the fuel tank.

A fluid dispensing nozzle including a nozzle body having a fluid path and a suction path therein. The nozzle includes a suction generator configured to generate a suction force in the suction path when fluid to be dispensed flows through the fluid path. The nozzle further includes a shut-off device having a suction chamber fluidly coupled to the suction path. The shut-off device is configured such that when the suction path is blocked during fluid dispensing the shut-off device prevents the nozzle from dispensing fluid through the fluid path. The suction chamber includes a lip extending around a perimeter thereof. An opening is formed in or extends through the lip, the opening providing fluid communication between the suction chamber and the suction path to enable liquid to flow from the suction chamber to the suction path.

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, wherein the fluid path includes an at least partially radially extending portion, 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. One of the first or second connectors has a shaft which defines or includes at least part of the fluid path therein, and the at least partially radially extending portion includes or is defined by an opening in the shaft.

A testing or filling adapter (1) for a container to be filled with fluid, composed of a body (10), an attachment module (3), and a coupling system (30) having a coupled position, in which a sealed connection is established between the body and the attachment module, and an uncoupled position. The body includes a feed module (2) that comprises a plurality of conduits that include at least one fluid conduit (221) and is equipped with a safety valve (5) that can be moved between an open configuration and a closed configuration and is connected to an element mirror (51) having a first configuration in which the safety valve is in the open configuration and a second configuration in which the safety valve is in the closed configuration. The filling adapter further comprises a safety device (6) that cooperates with the coupling system, with it being possible to move said safety device between a locked position, in which the safety device locks the coupling system in the coupled position, and an unlocked position, in which the safety device enables the coupling system to be moved into the uncoupled position. The safety device cooperates with the mirror element so as to enable the mirror element to be in its first configuration when the safety device is in the locked position, and to force the mirror element to be in its second configuration when the safety device is moved from its locked position to its unlocked position.

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.
