Abstract
A fuel vapor control valve comprising a housing fitted with an inlet port connectable to a fuel tank and an outlet port connectable to a fuel vapor recovery device. The inlet port and the outlet port are in flow communication via a first valve controlled passage admitting fuel vapor flow in a direction from the inlet port to the outlet port only when pressure within the fuel tank exceeds a threshold. A second valve controlled passage admits vapor flow in an opposite direction from the outlet port to the inlet port only when pressure within the fuel tank drops below pressure at the fuel vapor recovery device.
