Control valve for dual fuel operation of an internal combustion engine
This patent describes a control valve for a supplemental fuel supply to an internal combustion engine provided with a primary liquid fuel supply. The control valve comprises a valve housing provided with an air duct extending the length of the housing and having inlet and outlet ends; a movable air flow responsive member in the duct responsive to air flowing through the duct towards the outlet end so as to be deflected in a first direction in response to such air flow. The valve has a means for resiliently biasing the air flow responsive member in a direction opposite to the first direction; a supplemental fuel inlet in the housing; a supplemental fuel passageway in the housing to provide communication between the supplemental fuel inlet and the air duct at a point between the air flow responsive member and the outlet end of the duct; a valve element for controlling the supplemental fuel flow through the passageway. The valve element is movable between closed and open positions in response to the movement of the air flow responsive member between undeflected and deflected positions, respectively. The valve element is movable between the open and the closed positions independently of the air flow responsive member.
