The invention relates to an improved fuel tank isolation valve. More specifically, the present invention relates to an improved fuel tank isolation valve for maintaining fuel tank pressure within a protected pressure range, latching both end positions of the valve without current draw, and controlling fuel vapor flow from a fuel tank port to a canister port during fueling. The FTIV has axial control of over-pressure release and over-vacuum release functions.
本发明涉及一种改进的燃料箱隔离阀。更具体地,本发明涉及一种改进的燃料箱隔离阀,该改进的燃料箱隔离阀用于将燃料箱压力保持在受保护的压力范围内,在没有电流消耗的情况下闩锁阀的两个端部位置,并且在加燃料期间控制从燃料箱端口到罐端口的燃料蒸气流动。FTIV具有过压释放和过真空释放功能的轴向式控制。
