A vent shut-off assembly configured to manage venting on a fuel tank configured to deliver fuel to an internal combustion engine includes a first liquid vapor discriminator (LVD), a main housing, a first poppet valve assembly, a pump and an actuator assembly. The first LVD is disposed in the fuel tank. The main housing selectively vents to a carbon canister. The first poppet valve assembly has a first poppet valve arranged in the main housing. The pump selectively pumps liquid fuel from the main housing. The actuator assembly is at least partially housed in the main housing and includes a camassembly having a cam shaft that includes a first cam and a second cam. The first cam has a profile that one of opens and closes the first poppet valve fluidly coupled to the first LVD.
本发明公开了一种被构造为管理燃料箱上的排气的排气关断组件,该燃料箱被构造为将燃料递送到内燃机,该排气关断组件包括第一液体蒸气辨别器(LVD)、主壳体、第一提升阀组件、泵和致动器组件。该第一LVD设置在该燃料箱中。该主壳体选择性地向碳罐排气。该第一提升阀组件具有布置在该主壳体中的第一提升阀。该泵选择性地从该主壳体泵送液体燃料。该致动器组件至少部分地容纳在该主壳体中并且包括凸轮组件,该凸轮组件具有凸轮轴,该凸轮组件包括第一凸轮和第二凸轮。该第一凸轮具有打开流体联接到该第一LVD的该第一提升阀和关闭该第一提升阀中的一者的轮廓。
