Abstract: A non-overflow liquid delivery system comprises a pumping apparatus having a liquid delivery pumping portion and a liquid recovery pumping portion fluidically isolated one from the other. A nozzle has a liquid delivery conduit and a liquid recovery conduit. A liquid delivery hose connects the liquid delivery pumping portion of the pumping apparatus in fluid communication with the liquid delivery conduit. A liquid recovery hose connects the liquid recovery pumping portion of the pumping apparatus in fluid communication with the liquid recovery conduit. A valve has a first movable valve portion for opening and closing the liquid delivery conduit. A manually operable valve control mechanism is connected to the valve for controlling the first movable valve portion, and has a liquid sensor responsive to a threshold condition of liquid in the liquid recovery conduit to thereby cause the first movable valve portion to close the liquid delivery conduit.

Abstract: A nozzle for use in a non-overflow liquid delivery system comprises a nozzle body, a liquid delivery conduit having a liquid-receiving inlet and a liquid-dispensing outlet, and a non-bifurcated liquid recovery conduit having a liquid-receiving inlet and a liquid-conveying outlet. The minimum effective internal cross-sectional area of the liquid recovery throughpassage is greater than half the minimum effective internal cross-sectional area of the liquid delivery throughpassage. A valve has a first movable valve portion and a second movable valve portion that are interconnected one to the other for co-operative movement one with the other. A manually operable trigger is connected to the first movable valve portion for corresponding positive uninterruptable movement of the first movable valve portion between a valve-closed configuration and the valve-open configuration.

Abstract: Systems and apparatuses for fluid delivery. A system may include a container for containing fluid and a pump for pumping fluid from the container. There may be a dispensing outlet valve for mediating fluid flow through a dispensing outlet of the container, wherein the dispensing outlet valve is configured to permit flow from the container out the dispensing outlet when the pump is being pumped, and to automatically inhibit fluid flow from the container through the dispensing outlet when the pump is not being pumped.

Abstract: An attachment for communication of fluid from a fluid source. The attachment may include at least one fluid passage permitting fluid flow through the body of the attachment, and at least one valve engaging portion in the body. The valve engaging portion may be configured to open a valve of the fluid source when the attachment is attached to the fluid source or when the attachment is moved towards the fluid source.

Abstract: A vapor-recovery-activated auto-shutoff nozzle comprises a manually operable trigger that permits selective operation of a normally closed valve between a valve-closed configuration and a valve-open configuration. Linkage arms connect the trigger and the valve, and are re-configurable between an enabled configuration and a disabled configuration. In the enabled configuration, the trigger and the valve are operatively connected such that the rest position of the trigger corresponds to the valve being closed, and the in-use position of the manually operable trigger corresponds to the valve being open. In the disabled configuration, the manually operable trigger is precluded from controlling the valve.

Abstract: A liquid delivery system for supplying liquid from a portable container to a destination and removing vapor from the destination comprises a portable container, an elongate flexible liquid delivery hose, and an elongate flexible vapor recovery hose. The liquid delivery hose receives liquid from the portable container, and delivers the received liquid to a remote destination. The vapor recovery hose receives vapor from the remote destination, and delivers the received vapor to the substantially hollow interior of the portable container. The liquid delivery hose and the vapor recovery hose permit the movement of the liquid outlet of the liquid delivery hose to more than one selected remote destination while the container remains substantially stationary. Reduced air pressure in the portable container resulting from the removal of the liquid therefrom, causes vapor to be suctioned via the vapor recovery hose into the portable container.

Abstract: A portable fluid exchange system comprises a source container, a liquid and vapor pump for pumping liquid from the source container to the destination container and for pumping vapor from the destination container to the source container. The liquid inlet and vapor outlets of the liquid and vapor pump are connected in fluid communication with the source container. A liquid delivery hose delivers liquid from the pump to the destination container. A vapor delivery hose delivers vapor from the destination container to the pump. A selectively controllable actuation mechanism actuates the liquid and vapor pump to thereby concurrently pump liquid from the liquid and vapor pump through the liquid outlet and vapor into the liquid and vapor pump through the vapor inlet, and concurrently pump vapor from the liquid and vapor pump through the vapor outlet and liquid into the liquid and vapor pump through the liquid inlet.

Abstract: An automatic shut-off nozzle comprises a liquid delivery conduit and a liquid recovery conduit. A valve has a first movable valve portion movable between a valve closed position whereat liquid is precluded from being dispensed from the liquid-dispensing outlet of the liquid delivery conduit and a valve open position whereat liquid is permitted to be dispensed from the liquid-dispensing outlet of the liquid delivery conduit. A manually operable valve control mechanism is reconfigurable between an operating configuration whereat force can be transmitted from the valve control mechanism to the valve to thereby move the first movable valve portion to the valve open position, and a non-operating configuration whereat force cannot be transmitted from the valve control mechanism to the valve. A liquid sensor has a rest state and an actuated state whereat the liquid sensor reconfigures the manually operable valve control mechanism from the operating configuration to the non-operating configuration.
