초록 ▼

An apparatus for controlling the routing of fuel vapor in an automotive fuel vapor recovery system that includes a pressure actuated control valve. A vent line extends between the tank and the mouth of the filler pipe of the fuel system. A venturi member located in the vent line includes a signal port in communication with the control valve. Vapor flows through the vent line and venturi creates a low pressure signal which operationally acts on the control valve.

대표청구항 ▼

An apparatus for controlling the flow of fuel vapor within a motor vehicle fuel system that includes a fuel storage tank and a filler pipe in fluid engagement with the tank and having a mouth for receiving a fuel nozzle during the act of refueling comprising: a control valve capable of venting fuel vapor from a tank and adapted to be positioned on the tank and extend into the interior of the tank; a vent line in fluid engagement with the tank and adapted to extend to a position of fluid engagement with the filler pipe at a location proximate the mouth of the filler pipe; a venturi member positioned in said vent line and having a signal port; and a signal line in communication with said signal port and extending to a position of fluid engagement with said control valve, whereby the flow of fuel into the filler pipe creates a pressure differential between the tank and the filler pipe mouth and fuel vapor flows through said vent line and venturi from the tank to the filler pipe and the flow of fuel vapor past said signal port creates low pressure or a vacuum in said signal line, such low pressure or vacuum acting on said control valve.
