摘要： A pressure actuated poppet valve for a fuel dispensing nozzle is disclosed having a piston therein movable between a first and a second position. In the first position, the piston holds a plurality of coupling or latching balls in coupling engagement with an axially movable stem so that upon a user pulling the actuator handle or lever of the dispensing nozzle, the poppet valve is opened for the dispensing of fuel. When the dispenser goes off such that there is no fuel pressure in the hose upstream from the nozzle, a spring within the poppet valve pushes the piston from its first to its second position, thus permitting the coupling balls to move clear of the stem, allowing the poppet valve to close, and preventing opening of the poppet valve upon the subsequent actuating of the nozzle handle. The poppet valve has a flow restriction port which permits fuel to flow in and out of the poppet valve such that a predetermined time delay will result between the time the fuel dispenser is de-energized and the time the dispensing nozzle becomes inoperable. Upon energization of the dispenser, the fuel pressure will cause the piston to move to its first position, thus again enabling actuation of the fuel dispensing nozzle.
摘要翻译：公开了一种用于燃料分配喷嘴的压力促动提升阀，其具有可在第一和第二位置之间移动的活塞。在第一位置，活塞保持多个联接或闭锁的球与轴向可移动的杆联接接合，使得当用户拉动分配喷嘴的致动器手柄或杠杆时，提升阀被打开以分配燃料。当分配器熄灭使得在喷嘴上游的软管中没有燃料压力时，提升阀内的弹簧将活塞从其第一位置推到其第二位置，从而允许联接球移动远离阀杆，允许提升阀关闭，并且防止在随后致动喷嘴把手时提升阀的打开。提升阀具有流动限制端口，其允许燃料进入和离开提升阀，使得在燃料分配器断电的时间与分配喷嘴不能操作的时间之间将产生预定的时间延迟。在分配器通电时，燃料压力将导致活塞移动到其第一位置，从而再次使得能够致动燃料分配喷嘴。

摘要： A liquid dispensing device in the form of a so-called piston valve for use with a gasoline pump comprises a valve housing having an inlet connected to the pump and an outlet; a valve for controlling the flow of liquid from the inlet to the outlet; a discharge pipe connected to said outlet; and a manually operable operating mechanism for controlling movement of said valve, which operating mechanism comprises adjustable means which can be moved between an engagement position and a free position. In order to avoid the risk of unexpected flow of gasoline when the pump is activated, the movement of the adjustable means between said free position and said engagement position is arranged to take place in dependence upon the pressure of the gasoline at the inlet, and passage means are arranged for equalizing the overpressure at the inlet when the pump is deactivated when the valve is open or if an attempt is made to open the valve when the pump is deactivated and said pressure is sufficient to move the adjustable means.
摘要翻译：与汽油泵一起使用的所谓的活塞阀形式的液体分配装置包括一个具有连接到泵的入口和出口的阀壳体; 用于控制从入口到出口的液体流动的阀; 连接到所述出口的排放管; 以及用于控制所述阀的运动的手动操作的操作机构，该操作机构包括可在接合位置和自由位置之间移动的可调节装置。为了避免当泵被激活时汽油出现意外流动的风险，可调节装置在所述自由位置和所述接合位置之间的运动被设置为根据入口处汽油的压力和通道当阀门打开时，或者当泵被停用并且所述压力足以移动可调节装置时尝试打开阀门时，排气装置被设置用于均衡入口处的过压。

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 for a closed system holding a volatile fuel. The nozzle is adapted to sealably engage the filler pipe of a fuel tank to avoid passage of fumes to the atmosphere during a fuel transfer operation. The nozzle will automatically discontinue fuel flow in response to a reduction in flow rate within the closed system, which would otherwise cause recycling of fuel through the nozzle and back to its source.

摘要： A liquid dispenser having a liquid flow duct through which liquid may flow from a liquid source into a battery or the like. The dispenser includes a light-transmitting portion adjacent the flow duct to produce a visual indication of the surface elevation of a pool of liquid into which the liquid flows. Available light at the outer end of the light-transmitting portion passes in and through the latter to a reflective, inner end of the light-transmitting portion and is then reflected back out to provide a visual indication that the reflective end is not immersed in the pool of liquid. When the level of the pool has risen to immerse the reflective end, the available light reaching the reflective end is refracted into the liquid, and immersion is indicated by the relative absence of reflection.
