Abstract: A device for controlling fluid flow between an evaporative emission space of a fuel tank and a fuel vapor collection canister that includes a housing, a valve, a seal, an electric actuator, an electric transducer, and an electrical connector. The housing includes a first port, a second port, and a fluid flow path that extends between the first and second ports. The first port is adapted for receiving fluid flow from the evaporative emission space and is at a first pressure level. The second port is adapted for supplying fluid flow to the fuel vapor collection canister and is at a second pressure level. The valve is 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 permits substantially unrestricted fluid flow between the first and second ports. The second configuration prevents fluid flow between the first and second ports.

Abstract: A fuel tank pressure sensor assembly includes a pressure sensing element portion and a rollover valve portion. An area of reduced section between the sensor element portion and the valve portion provides a controlled fracture location for the pressure sensor assembly. In addition, the valve portion prevents inadvertent closure under normal vehicle operating conditions.
