ABSTRACT:
A vapor control system includes a vapor receiver having an inlet through which vapor is received, an outlet through which vapor is discharged, and a control valve having a first inlet in communication with the outlet of the fuel receiver, a second inlet in communication with a pressure source and an outlet. The control valve also includes a valve having a closure moveable between a first position, preventing communication between the first inlet and the outlet, and a second position permitting communication between the first inlet and the outlet in response to a pressure signal over a threshold pressure provided from the pressure source through the second inlet. Movement of the closure to its second position permits routing of vapor from the vapor receiver, through the first inlet and out of the outlet of the control valve.
