摘要： A rack, which cooperates with a trigger of a manually operated handle of an automatic shut-off nozzle, is removably mounted on the nozzle guard so that the nozzle can be utilized in a mechanical hold open mode or a manually controlled mode when the rack is mounted on the guard and cannot be utilized in the mechanical hold open mode when the rack is removed but only in the manually controlled mode.

摘要： A fuel dispensing nozzle is provided with a view glass/fuel flow indicator that are disposed between the main fuel valve and a downstream check valve. The view glass/flow indicator means comprise a pair of horizontally aligned view glasses. A plurality of embodiments illustrate the use of different sub-assemblies in providing the view glass/flow indicator functions, as well as different provisions for obtaining a seal that prevents leakage of fuel at the view glass units.

摘要： A linkage assembly for linearly moving a valve of a coupler between its open and closed positions has a yoke pivotally connected to a first link which is fixed to a rotary shaft so that the yoke rotates about the axis of the rotary shaft during a predetermined angular rotation of the rotary shaft. The yoke and a second link, which is pivotally connected to the valve, are in bearing engagement during the predetermined angular rotation. During a portion of the predetermined angular rotation, the center of the bearing surface of the second link is maintained in alignment with the axis of rotation of the shaft by a pin on the second link riding in an arcuate channel fixed to the shaft for rotation therewith.

摘要： A dry disconnect coupling comprises an adapter connected to a liquid conduit and a coupler connected to another liquid conduit. The adapter and coupler each have poppets which seal passageway outlets thereof when they are disconnected. When connected, means are provided for simultaneously opening the poppets by displacing them with their end faces in contiguous relation. An O-ring, mounted in a groove in the end face of the coupler poppet sealingly engages the end face of the adapter poppet to prevent wetting of the end face surfaces of the poppets and thereby minimize liquid which could be a source of liquid when the coupler is disconnected from the adapter. Six alternate sealing rings, for providing an end face seal, are described.

摘要： A swivel connector between a hose reel and a source of product has a first body secured to the source of product and a second body secured to the hose reel. The first body has a plurality of stepped bores cooperating with various outer surfaces of the second body. A pair of non-metallic, non-corrosive bearings is disposed between two different stepped bores and two different outer surfaces with a seal ring disposed therebetween. A plastic thrust ring is disposed between a shoulder of the first body and a first surface of a thrust flange of the second body to absorb the thrust due to relative movement of the second body into the first body. The thrust flange has a second surface, which is parallel to the first surface, against which a first wear ring bears. The first wear ring has a plurality of balls bearing thereagainst on its side remote from the thrust flange. A retainer is supported on the first body and has a flange providing a surface against which a second wear ring abuts. The second wear ring also bears against the balls, which absorb the thrust due to relative movement of the second body out of the first body. The two non-metallic, non-corrosive bearings absorb the bending loads.
摘要翻译：软管卷轴和产品源之间的旋转连接器具有固定到产品源的第一主体和固定到软管卷轴的第二主体。第一主体具有与第二主体的各种外表面配合的多个阶梯孔。一对非金属，非腐蚀性轴承设置在两个不同的阶梯孔和两个不同的外表面之间，其间设置有密封环。塑料推力环设置在第一主体的肩部和第二主体的推力凸缘的第一表面之间，以吸收由于第二主体相对于第一主体的相对运动而产生的推力。推力凸缘具有平行于第一表面的第二表面，第一磨损环与该第一表面相对。第一耐磨环具有多个在其远离推力凸缘的一侧支承的滚珠。保持器支撑在第一主体上并且具有凸缘，凸缘提供第二磨损环邻接的表面。第二磨损环也承受着由于第二体离开第一体的相对运动而吸收推力的球。两个非金属，非腐蚀性轴承吸收弯曲载荷。
