ABSTRACT:
A breakaway unit which is adapted to be mounted in series flow relation with a fuel nozzle. The breakaway unit comprises a flex section which assures an axial transmission of forces to a valve section which is separated when a vehicle drives away from a dispensing unit with the nozzle lodged in its fuel tank. The valve section comprises inlet and outlet couplers and means for releasable locking the couplers in an assembled relation. These means comprise fingers which are flexed outwardly when a separating force exceeds a predetermined value. Garter springs embrace the fingers to accurately control at which the couplers will separate. The fingers engage angularly spaced lugs which permit the fingers to be telescoped therebetween and then rotated to a locking position to facilitate reassembly of the couplers with a minimum of effort. Alternate embodiments of the invention disclose other forms of spring means for accurately controlling the force at which the couplers will separate. Also disclosed are alternate constructions which minimize the effort required for reassembly.
