Abstract: A nozzle for dispensing fluid including a nozzle body having a fluid path through which fluid to be dispensed is configured to flow. The nozzle includes a main fluid valve positioned in the fluid path to control the flow of fluid therethrough, and a secondary fluid valve positioned in the fluid path to control the flow of fluid therethrough. The secondary fluid valve includes a secondary valve body and a secondary valve seat, the secondary valve body being movable between a closed position, wherein the secondary valve body sealingly engages the secondary valve seat, and an open position wherein the secondary valve body is spaced away from the secondary valve seat. The nozzle further includes an actuator operatively coupled to the main and secondary fluid valves. The actuator and main and secondary fluid valves are configured such that initial actuation of the actuator opens only the secondary fluid valve and not the main fluid valve.

Abstract: A nozzle including a dispensing path, where the dispensing path is configured such that fluid is dispensable through the dispensing path. The nozzle further includes a suction path, where the suction path is configured such that a negative pressure is created in the suction path when fluid flows through the dispensing path. The nozzle also has a fluid recapture path configured to capture fluid, positioned on an outside of the nozzle, in the recapture path. The fluid recapture path is in fluid communication with the dispensing path and the suction path. In this manner fluid in the fluid recapture path is directable into the dispensing path by the negative pressure in the suction path.

Abstract: A nozzle for dispensing fluid including a nozzle body having a fluid path which is configured to receive fluid therein and a vapor path which is configured to receive vapor therein. The nozzle further includes a main fluid valve positioned in the fluid path to control a flow of fluid therethrough, the main fluid valve including a main fluid valve spring configured to bias the main fluid valve to one of its open or closed positions. The nozzle further has a main vapor valve positioned in the vapor path to control a flow of vapor therethrough. The main vapor valve includes a main vapor valve spring configured to bias the main vapor valve to one of its open or closed positions. At least part of the main fluid valve spring or the main vapor valve spring is positioned within the other one.

Abstract: A nozzle system including a nozzle body configured to dispense fuel through a fuel path thereof into a vehicle tank. The nozzle body includes a vapor path configured such that vapor recovered from the vehicle tank during refueling is passable therethrough. The nozzle system further includes a main vapor valve positioned in the vapor path and configured to selectively block the vapor path. The main vapor valve is movable to a position wherein the main vapor valve does not block the vapor path. The nozzle system further includes a relief valve in fluid communication with the vapor path. The relief valve is configured to open to allow ambient air to enter into the vapor path when sufficiently low pressure is present in the vapor path, and the relief valve is generally aligned with the main vapor valve.

Abstract: An emergency shutoff valve includes a fluid conduit having a frangible area defined therein, a valve member operatively coupled to said conduit upstream of the frangible area, an expansible chamber having the frangible area defined therein, a movable member defining at least a portion of the expansible chamber, and a linkage operatively coupled to the movable member and the valve member for shutting the valve upon movement of the movable member in response to leakage of fluid through the frangible area. A method of shutting off fuel includes defining an expansible chamber about a frangible area in the conduit, moving a member defining a portion of the expansible chamber in response to leaking fuel, and shutting off a fuel valve in response to moving the movable member.

Abstract: An emergency shutoff valve is provided that includes a housing defining a fluid inlet, a fluid outlet and a fluid flow passage extending therebetween. The valve includes a valve element disposed within the housing and releasably latched in an open position by a latching mechanism. An expansible member defines at least a portion of a sealed expansible chamber that is sealed at locations downstream and upstream of a weakened portion of the housing.
