ABSTRACT:
In combination with a standard carburator for an internal combustion engine having a butterfly type throttle valve, a means is provided having a passageway with another butterfly type valve and the means is disposed between the carburator and the engine wherein the added valve rotates about an axis disposed normal to the axis of rotation of the throttle valve. Linkage means are provided so that both valves open and close together. A cylindrical chamber is provided with one end opened to the atmosphere and a piston is disposed slideably therein. A compression spring within the chamber urges the piston towards the open end to seat against an internal shoulder formed in the cylinder. Two ducts are provided whereby one end of each duct communicates with the passageway in the means, upstream of the valve therein, and one end of the other duct communicates with the passageway downstream of the valve. The duct with its end upstream of the valve has its other end communicating adjacent the shoulder but within the chamber so that atmospheric pressure can be sealed off from this end of the duct. The other duct has its other end communicating within the chamber. Means are provided to adjust the urging force of the compression spring so that the engine and means are made compatable.
