The invention relates to a leak-proof fuel tank isolation valve with a single seal and diaphragm to improve shaft alignment. The invention relates to an improved fuel tank isolation valve. More specifically, the present invention provides a system that includes an over pressure relief (OPR) and over vacuum relief (OVR) sealing, thereby eliminating misalignment and customizing the seal with a smaller number of components. Furthermore, the invention enhances low emissions and limits entry of contaminants to prolong the service life of the system.
一种具有单个密封件及隔膜以改进轴对准的防漏燃料箱隔离阀,本发明涉及改进的燃料箱隔离阀。更具体地说,本发明提供一种系统以包含过压力释放(over pressure relief;OPR)及过真空释放(over vacuum relief;OVR)密封,从而消除未对准并用较少数目的部件定制密封。此外,本发明增强低排放并限制污染物的进入,以增加该系统的寿命。
