Abstract
A power valve assembly for use in combination with a carburetor for an internal combustion engine, where such carburetor has structure defining a fuel reservoir, is shown as having a valve body and cooperating valve member effective for opening and closing related passage means leading to the carburetor induction passage for at times supplying additional enrichening fuel flow thereto; a pressure responsive movable diaphragm has an associated actuator connected thereto and is exposed to a source of engine vacuum of varying magnitude as to at times move the valve member in a direction causing the valve member to move relative to the valve body and permit the flow of such enrichening fuel flow; the direction of movement of the diaphragm and associated actuator describing a path which is other than parallel to the path described by the direction of movement of the valve member.
