摘要： 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.

摘要： A vapor recovery nozzle, employed in minimizing atmospheric pollution by fuel vapors is described. The nozzle comprises a bellows which is compressed against the fill pipe of a vehicle fuel tank during discharge of fuel therein. The bellows surrounds a nozzle spout to define a vapor return flow path which extends through a nozzle body. The body of the nozzle is compositely formed by a body member and a vapor path cap which compositely define the vapor return flow passage. Flow of fuel is controlled by a control valve which may be opened, or maintained opened, by an operating lever only when a trip mechanism stem is latched in an operative position. A mechanical interlock prevents latching of the trip mechanism stem unless the bellows is compressed in sealing engagement with a fill pipe. When the bellows is so compressed, the trip stem is latched. If the level of fuel in the fill pipe covers the end of the spout, vacuum actuated means unlatch the trip mechanism stem. If the pressure in the vapor return flow path rises to a level indicating a blockage in return flow, the trip stem is also unlatched. A vapor valve is provided in the bellows to prevent the escape of fuel vapors when the nozzle is in a rest position. Angular relationships of the bellows and the spout facilitate obtaining a seal with a fill pipe. A groove is formed in the spout outwardly of and adjacent the vapor seal so that the vapor seal maintains its integrity in the event the spout is broken when inserted in a fill pipe. A trip mechanism sub-assembly, a spout sub-assembly and a bellows sub-assembly facilitate rebuilding, as well as the original assembly, of the nozzle.
摘要翻译：描述了用于使燃料蒸气中的大气污染最小化的蒸气回收喷嘴。喷嘴包括在燃料排出期间压缩在车辆燃料箱的填充管上的波纹管。波纹管围绕喷嘴喷口以限定延伸穿过喷嘴体的蒸汽返回流动路径。喷嘴的主体由主体部件和复合地限定蒸汽返回流动通道的蒸气通道帽复合地形成。只有当跳闸机构杆被锁定在操作位置时，才能由操作杆打开或保持打开的控制阀来控制燃料的流动。机械互锁防止脱扣机构杆的闩锁，除非波纹管与填充管密封接合而被压缩。当波纹管被压缩时，跳闸杆被锁住。如果填充管中的燃料水平覆盖喷嘴的端部，则真空致动装置解除脱扣机构杆。如果蒸汽返回流路中的压力上升到表示回流阻塞的水平，则脱扣杆也被解锁。在波纹管中设置蒸气阀，以防止当喷嘴处于静止位置时燃油蒸汽逸出。波纹管和喷嘴的角度关系便于利用填充管获得密封。在蒸汽密封件的外部和邻近蒸气密封件处形成凹槽，使得蒸汽密封件在插入填充管道时在喷口破裂的情况下保持其完整性。跳闸机构子组件，喷口子组件和波纹管子组件便于喷嘴的重建以及原始组件。

摘要： A liquid dispensing nozzle of the automatic shut-off type has the trigger, which holds the valve actuating means in an open position, or its retaining means formed to flex when subjected to a force beyond that exerted by the valve actuating means when it is in any set flow position so that the trigger is automatically released from its retaining means if the nozzle should be accidentally removed from the fill pipe, for example.

摘要： A fluid dispensing nozzle construction and method of making the same are provided, the construction comprising a valve body having a dipensing spout extending therefrom, and a flexible bellows-like tube of polymeric material telescopically disposed on the spout and having opposed ends one of which is secured to the valve body and the other of which carries a face seal means for engaging an annular lip of a fill pipe of a fluid storage tank to seal around an opening in the fill pipe when the spout is inserted therein, the spout and the tube defining a vapor recovery passage therebetween that leads from the seal means to the valve body. The spout has a valve seat member thereon and the tube carries a valve member that moves therewith and that cooperates with the valve seat member to close the passage intermediate the seal means and the valve body when the tube is in a certain first compressed condition thereof between the seal means and the valve body and to open the passage when the tube is in a certain greater compressed condition thereof between the seal means and the valve body. The valve member has an internal annular surface that slides over at least part of the valve seat member in sealing engagement therewith to close the passage when the tube is in the first compressed condition thereof.
