浮标室阀件-中英对照
An end plate 52 having one or more drain slots 54 formed therein seals the lower end of lower portion 28 to retain float 46 within the valve.
在平面52有一个或多个水槽54， 对下端部分28进行封闭，是浮标46停在阀件内。
Float 46 is freely axially slidable within the float chamber defined by lower portion 28 of the valve body, limited in its upward travel by valve seat 34, and in its downward travel by end plate 52. Guide rods 29 on the inside periphery of float chamber 28 mate with grooves 25 in float 46 to prevent it from rotating within the float chamber. As float 46 is raised and lowered by changes in the level of liquid fuel communicating with the float through radial ports 30 and drain slots 54 in end plate 52, a valve element 40 connected to the upper surface of the float is correspondingly raised up or down. With float 46 in the fully raised position shown in broken lines in FIG. 2, valve element 40 is in the closed position in which the valve element covers and seals valve seat 34. In its lowermost position shown in solid lines in FIG. 2, float 46 has peeled valve element 40 off valve seat 34.
浮标46由阀件的下端部分28决定，能够在浮标室内自由的在轴方向进行滑动。通过阀件34限定其向上的冲程，向下的冲程通过平面52限定。导柱29在浮标28周边与凹槽25相匹配，防止其在浮标室内旋转。浮标46根据液体燃料上升和下降的变化，通过放射状通气口30和水槽54同燃料箱在平面52处连接。阀芯40和燃料箱的上表面连接，做相应的上下运动。当浮标46如图2上升时，阀芯将阀件34覆盖并封闭。在如图2中最低处，浮标46将阀芯40和阀件34分离开来。
In a particularly advantageous embodiment, a pressure relief valve 35 is connected to upper portion 26 to vent the tank to the atmosphere in excess pressure conditions.
该发明特征的特别优势在于，压力释放阀35通过上端部分，接燃料箱连接大气压，以免在压力过大的情况发生。
When the vehicle is sharply tilted or rolled over as in FIG. 10, gravity and spring 55 acting on the float 46 force it toward the valve seat 34 and the closed valve position. When oriented sideways the float may not be submerged in fuel, such that only spring 55 exerts closure force on float 46 against the friction between the float and the float chamber. It is therefore preferable that spring 55 or other rollover assist structure be sufficient to close float 46 when lying on its side, without the assistance of gravity or fuel buoyancy.
当车辆如图10所虱，发生突然倾斜或翻滚时，重力、弹簧55对浮标46施力，使其运动到阀件34处进行关闭。当斜向的方位没有被燃料浸泡时。只有弹簧55，克服浮标和浮标室之间的摩擦力进行封闭。最好是可以在不使用弹簧55或其它翻滚器，在浮标倒下时，不使用浮标筒或借助重力进行封闭的方式。
Referring to FIGS. 2 to 4, the details of the valve element and vent outlet in a first embodiment of the invention are set forth. As previously described, valve seat 34 defines an essentially circular vent outlet 32. Valve element 40 is in the form of a thin, fairly rigid plate or paddle, in the illustrated embodiment made from Celcon, the trade name for an acetal resin made by Hoechst Celanese, or from a nylon material. It will of course be understood by those skilled in the art that other suitable fuel-resistant materials may be used, including for example other non-brittle resins or even metal. As best shown in FIG. 11, valve element 40 has a rounded vent closure end 41 and a lever arm portion generally comprising two prongs 43 with a rectangular cutout region 45 for attachment to post 47 on float 46 in a snap fit. Although the vent closure portion 41 of paddle 40 is shown as circular, any shape is suitable as long as it sufficiently seals and interacts with vent opening 32 and outlet 34.
参见图2-4 突出了阀芯和出气口的第一种特征的详细描述，如上所述，阀件34决定着圆柱形的出气口32。阀芯40为细长、挺直的金属片或桨状物，采用聚甲撑氧制成，商标名为Hoechst Celanese生产的缩醛树脂，或使用尼龙材料。也可以使用其他合适的防油材料。包括其他的非脆性材料的树脂。如图11所示，阀芯40为圆形的出气口，而杠杆臂部分通常由二个带有方形剪口45的突出物43，用来连接通过爪状物固定的浮标46上的柱状物47。尽管在桨状物40的出气口关闭部分41为圆形，在保证封闭和出气口开放处32，34的互动的前提下，允许采用其它的形状。
While valve element 40 in the illustrated embodiments of FIGS. 1-11 is essentially rigid, it can also be made from a more flexible, pliable material if desired. A pliable valve element 40 has the advantage of forming a tighter more conforming seal with the valve seat, but it will be somewhat less responsive in opening than a rigid valve element.
图1-11中所示的阀芯40是刚性的，如果有必要，可以采用有弹性的、具有可塑的材料。有弹性的阀芯40具有产生更紧密的封和的优势，但是有时和刚性阀芯相比反映较慢。
