浮標(biāo)室閥件-中英對照

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有一個或多個水槽54， 對下端部分28進(jìn)行封閉，是浮標(biāo)46停在閥件內(nèi)。
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.
浮標(biāo)46由閥件的下端部分28決定，能夠在浮標(biāo)室內(nèi)自由的在軸方向進(jìn)行滑動。通過閥件34限定其向上的沖程，向下的沖程通過平面52限定。導(dǎo)柱29在浮標(biāo)28周邊與凹槽25相匹配，防止其在浮標(biāo)室內(nèi)旋轉(zhuǎn)。浮標(biāo)46根據(jù)液體燃料上升和下降的變化，通過放射狀通氣口30和水槽54同燃料箱在平面52處連接。閥芯40和燃料箱的上表面連接，做相應(yīng)的上下運動。當(dāng)浮標(biāo)46如圖2上升時，閥芯將閥件34覆蓋并封閉。在如圖2中最低處，浮標(biāo)46將閥芯40和閥件34分離開來。
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.
該發(fā)明特征的特別優(yōu)勢在于，壓力釋放閥35通過上端部分，接燃料箱連接大氣壓，以免在壓力過大的情況發(fā)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.
當(dāng)車輛如圖10所虱，發(fā)生突然傾斜或翻滾時，重力、彈簧55對浮標(biāo)46施力，使其運動到閥件34處進(jìn)行關(guān)閉。當(dāng)斜向的方位沒有被燃料浸泡時。只有彈簧55，克服浮標(biāo)和浮標(biāo)室之間的摩擦力進(jìn)行封閉。最好是可以在不使用彈簧55或其它翻滾器，在浮標(biāo)倒下時，不使用浮標(biāo)筒或借助重力進(jìn)行封閉的方式。
 

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.
參見圖2-4 突出了閥芯和出氣口的第一種特征的詳細(xì)描述，如上所述，閥件34決定著圓柱形的出氣口32。閥芯40為細(xì)長、挺直的金屬片或槳狀物，采用聚甲撐氧制成，商標(biāo)名為Hoechst Celanese生產(chǎn)的縮醛樹脂，或使用尼龍材料。也可以使用其他合適的防油材料。包括其他的非脆性材料的樹脂。如圖11所示，閥芯40為圓形的出氣口，而杠桿臂部分通常由二個帶有方形剪口45的突出物43，用來連接通過爪狀物固定的浮標(biāo)46上的柱狀物47。盡管在槳狀物40的出氣口關(guān)閉部分41為圓形，在保證封閉和出氣口開放處32，34的互動的前提下，允許采用其它的形狀。
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.
圖1-11中所示的閥芯40是剛性的，如果有必要，可以采用有彈性的、具有可塑的材料。有彈性的閥芯40具有產(chǎn)生更緊密的封和的優(yōu)勢，但是有時和剛性閥芯相比反映較慢。
