Roe, D A

This patent describes an apparatus for use in combination with the fuel induction system of an internal combustion engine. The internal combustion engine includes at least one combustion chamber, and the fuel induction system includes fuel supply means of providing a fuel mixture of air and liquid and an inlet manifold having an inlet opening for normally receiving the fuel mixture and communicating with at least one combustion chamber. A variable vacuum is drawn in the inlet manifold in response to operation of the engine. The valve comprises: a. a body including a bore having a continuous sidewall and having an inlet end for receiving the fuel mixture and a discharge end communicating with the intake manifold; b. valve means including a throttle valve residing in the normal path of the fuel mixture exiting the discharge end of the bore; c. guide means coupling the valve means to the body for reciprocal movement of the throttle valve in extendible and retractable directions relative the discharge end of the base; and d. biasing means normally urging the throttle valve in the retractable direction, the throttle valve being movable in the extendible direction in response to the vacuum in the manifold.
