Abstract
A valve assembly is provided that can perform an overpressure relief function to vent fluid from a first component, such as to vent fuel vapor from a fuel tank, to a second component, such as a carbon canister, without being affected by the vapor pressure in the vent line to the second component. That is, the valve opens to provide pressure relief when needed regardless of the vapor pressure against which it opens. The valve assembly may also include a solenoid that is controllable to allow fluid flow separately from the movement in response to vapor pressure.
