Abstract:
A housing has a fuel chamber formed therewithin. A fuel flow path is formed to and from the chamber. A plurality of air passageways are formed through the housing. A movable plate member has a plurality of spaced ports formed therein, and is movable from an open to a closed position. In the closed position, the holes in the plate are misaligned with the outlet end of the flow passageways, thereby precluding air flow therethrough; and, when the plate is moved to the open position, the holes in the plate are brought into registry with the passageways, thereby permitting flow of air to occur therethrough. A cam is formed on the plate and reciprocates a valve element respective to a valve seat. The valve is located to control flow from the fuel chamber, through the valve, and through the plate member. The fuel flow control and the air flow control are arranged respective to one another so that a constant ratio of air/fuel is maintained as the fuel valve and the air supply are throttled between the opened and closed positions.
