Abstract
A vent shut-off assembly configured to manage venting on a fuel tank includes a main housing, a poppet valve and an actuator. The main housing is positioned outside of the fuel tank and selectively vents to a canister. The poppet valve is disposed in the main housing and includes a plunger that provides over pressure relief (OPR) and over vacuum relief (OVR) functions. The actuator assembly can be housed in the main housing and includes a cam assembly having a cam shaft that includes a cam having a profile that one of opens and closes the poppet valve. When the poppet valve is in the closed position, vapor is precluded from passing between the fuel tank and the canister. When the poppet vale is in the open position, vapor is permitted from passing between the fuel tank and the canister.
