A swivel adapter for an inlet conduit to an underground storage includes two relatively rotatable components. The relative rotation between the components prevents sealing loss between the adapter and the inlet conduit when the adapter is subjected to torque.

A breakaway unit which is adapted for mounting in a fuel hose between a fuel dispenser and nozzle. The breakaway unit comprises male and female couplers which are normally locked in an assembled position, but which are releasable at a separation force produced when a vehicle drives away from the dispenser with the nozzle lodged in its fuel tank. The couplers include fuel passages which are adapted for connection to a fuel hose in series flow relation and valves disposed in the fuel passages and automatically shiftable from an open to a closed position when the couplers are separated. Fixed abutment lugs are formed on one of the couplers and are shaped to engage force fingers carried by the other coupler. Moveable lugs having ramped abutment surfaces are located on the fingers and engage ramped surfaces on the fixed abutment lugs to lock the couplers together. A sleeve is adjustably mounted on the force fingers to control the separation of the couplers.

A fuel nozzle has a modular construction wherein valve, venturi and spout modules are mounted in a bore formed in a nozzle body. The main fuel valve is controlled, independently of fuel pressurization, in response to a mechanical signal input, acting through a servo valve. The mechanical signal input is provide by a finger displaced trigger, acting through a pivotal lever arm and latching means that form part of the automatic shut off means for preventing overfill of a fuel tank. The venturi module has a venturi passage for generating a vacuum employed in the automatic shut off mechanism. The venturi module includes a bypass passage that enables sufficient vacuum force to be generated at both high and low flow rates. The spout module comprise an extruded spout (including a venturi vent passage) and a pair of mechanical adapter shells that are mechanical locked onto the spout and mechanically locked to the nozzle body, to secure the several modules in assembled relation.
