Fuel flow activated fuel vapor control apparatus

摘要

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.
