    摘要: 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.

    摘要: A roll-over vent valve comprising a housing formed with a fluid inlet and a fluid outlet, a valve seating bounding an outlet aperture of the housing, a float member received within the housing and axially displaceable between a sealed position wherein a sealing member thereof sealingly bears against the valve seating of the outlet aperture to seal the fluid outlet, and an open position wherein the sealing member is disengaged from the valve seating whereby the fluid outlet is in flow communication with the fluid inlet. There is further provided a pressure-retention device extending intermediate the valve seating and the fluid outlet, to thereby shut fluid flow therebetween as long as pressure differential between the fluid inlet and the fluid outlet does not exceed a minimal pressure threshold. The valve further comprises a one-way fluid inlet valve being in flow communication with said fluid outlet to allow fluid flow towards said fluid inlet a substantially high flow rate at the event of under-pressure at the fluid inlet.
