Fluid-responsive vent control valve with peel-away opening action
采取剝離式開(kāi)啟動(dòng)作的流體反應(yīng)出口控制閥
Abstract
摘要
The present invention comprises a rollover vent valve for mounting on a vehicle fuel tank to selectively vent fuel vapor from the fuel tank to a vapor trap such as a carbon canister. The valve includes a liquid fuel responsive control element connected to a valve element via lever arm structure to move the valve element between open and closed venting positions on a valve seat. The mechanical opening advantage obtained with the lever arm structure provides for a powerful peel-away action to ensure opening of the valve despite a tank/canister pressure differential acting to maintain the valve element in the closed position. In one embodiment the lever arm structure includes a hammer-claw mechanism to provide an initial pivotal opening force using the maximum potential of the lever arm, and a subsequent rectilinear opening force.
本發(fā)明是安裝在汽車(chē)燃料箱上的搖晃止回閥，以便有選擇性的從燃料箱中排放汽油蒸汽到除水閥內(nèi)，如碳罐。搖晃止回閥包括一個(gè)液體燃料反應(yīng)控制元件，通過(guò)杠桿臂結(jié)構(gòu)與閥芯連接，便于閥芯在閥座上的開(kāi)，關(guān)排氣位置之間的進(jìn)行移動(dòng)。通過(guò)杠桿臂結(jié)構(gòu)，采用強(qiáng)有力的剝離動(dòng)作，獲得機(jī)械開(kāi)啟優(yōu)勢(shì)，確保箱/罐在不同壓力差狀態(tài)下，使閥芯維持在關(guān)閉的位置上。杠桿臂結(jié)構(gòu)的一個(gè)特征是包括有一個(gè)爪錘機(jī)械裝置，通過(guò)使用杠桿臂的最大潛能提供啟動(dòng)的樞軸開(kāi)啟力，包括隨后的直線開(kāi)啟力。

We claim:
我們聲明：
1. A liquid- and gravity-responsive rollover vent control valve for mounting on a fuel tank to selectively vent fuel vapor from the tank to a vapor trap such as a carbon canister, the valve comprising:
1. 安裝在燃料箱上的液體和重力反應(yīng)搖晃止回閥是為了有選擇性的從燃料箱中排放出汽油蒸汽到除水閥中，如碳罐裝置，閥件包括：
a hollow valve body having a fuel vapor inlet communicating with the tank interior and a fuel vapor vent outlet communicating with the vapor trap;
空心閥體上的汽油蒸汽入口與燃料箱內(nèi)部連接，汽油蒸汽出氣口與除水閥連接；
valve means associated with the vent outlet, the valve means movable between an open venting position and a closed non-venting position;
閥裝置與出氣口相連接，該閥裝置可在開(kāi)口的排氣位置和關(guān)閉的非排氣位置之間移動(dòng)；
fuel level responsive control means in the hollow valve body connected to the valve means to open and close the valve means in response to the level of liquid fuel in the tank; wherein,
空心閥體中的燃料水平反應(yīng)控制裝置與閥裝置連接以通過(guò)開(kāi)，關(guān)閥裝置對(duì)出燃料箱中流體燃料的水平位置做出反映；其中，
the valve means include lever means extending radially from the vent outlet and connected to the control means at a point spaced radially from the vent outlet to amplify the opening force applied to the valve means by the control means, the lever means connected to the control means by lever actuator means, the lever actuator means comprising an axial guide defining a first axial range of travel for the lever means relative to the control means, the lever actuator means further comprising a contact element defining a second pivotal range of travel for the valve means relative to the control means, the contact element including two contact points of varying height relative to the control means to limit the second pivotal range of travel of the lever means relative to the control means.
閥裝置包括杠桿裝置從閥排氣出口放射性的延伸出去，并在與控制裝置在一分段點(diǎn)處連接，從放射性排氣出口以通過(guò)控制裝置擴(kuò)大開(kāi)啟力度，并被用于閥裝置上，杠桿裝置與控制裝置通過(guò)握柄傳動(dòng)裝置連接，握柄傳動(dòng)裝置包括一個(gè)軸向引導(dǎo)，為杠桿裝置決定第一次與控制裝置有關(guān)的軸向活動(dòng)范圍，握柄傳動(dòng)裝置還包括一個(gè)接觸元件，為杠桿裝置決定第二次與控制裝置有關(guān)的樞軸活動(dòng)范圍，接觸元件包括兩個(gè)接觸點(diǎn)，相對(duì)于控制裝置而言兩個(gè)接觸點(diǎn)高度不同以便限制與控制裝置相關(guān)的杠桿裝置的第二次樞軸活動(dòng)范圍。
2. A rollover vent control valve as defined in claim 1, wherein the two contact points are aligned with the vent outlet, a first lower contact point at a maximum distance from the vent outlet to provide an initial pivotal opening moment to the lever means, and a second higher contact point nearer the vent outlet to provide a locking connection and subsequent rectilinear opening force to the lever means.
