Patent ID: 6843271

Claim:
A device for controlling fluid flow between an evaporative emission space of a fuel tank and a fuel vapor collection canister, the device comprising: a housing having a body portion and a cover portion, the body portion including a first port, a second port, and a fluid flow path extending between the first and second ports, the first port being adapted for receiving fluid flow from the evaporative emission space and being at a first pressure level, and the second port being adapted for supplying fluid flow to the fuel vapor collection canister and being at a second pressure level; a valve movable along an axis with respect to the housing between a first configuration, a second configuration, and an intermediate configuration between the first and second configurations, the first configuration permitting substantially unrestricted fluid flow between the first and second ports, and the second configuration substantially preventing fluid flow between the first and second ports; a seal being located at an interface between the housing and the valve, the seal including an annular lip projecting obliquely with respect to the axis in the first configuration of the valve; an electric actuator being disposed within the housing and extending between a first end operatively coupled to the valve and a second end; an electric transducer being disposed proximate the second end of the actuator within the cover portion and in fluid communication with the fluid flow path, the electric transducer sensing the first pressure level and providing a first electric signal used in controlling the electric actuator, wherein the first pressure level comprises a negative pressure relative to ambient, and the first electric signal is provided to a first subset of the second set of terminals; and an electrical connector being disposed within the cover portion, the electrical connector including a first set of terminals in electrical communication with the electric actuator and including a second set of terminals in electrical communication with the electric transducer.
