Patent ID: 7063101

Claim:
A fuel tank vent system comprising a fuel vapor vent apparatus adapted to be coupled to a fuel tank to discharge fuel vapor located in the fuel tank to an external destination outside the fuel tank, a vent controller including a controller housing coupled to the fuel vapor vent apparatus and a first valve positioned in the controller housing and adapted to control discharge of fuel vapor from the fuel tank through the fuel vapor vent apparatus to the external destination and block discharge of liquid fuel from the fuel tank through the fuel vapor vent apparatus to the external destination, and means for blocking discharge of fuel vapor and liquid fuel from the fuel tank through the fuel vapor vent apparatus to the external destination in response to displacement of at least a portion of the controller housing relative to the fuel vapor vent apparatus due to application of a displacement force to the at least the portion of the controller housing upon deformation of the fuel tank caused by an impact against the fuel tank.
