    摘要： A high performance power valve for a carburetor. The valve is operated by engine manifold vacuum. A housing is provided having an annular flange portion through which extend rectangular outlet apertures for conducting fuel received from a tubular aperture in the housing to a power valve channel restriction. Preferably, four such outlet apertures are disposed at radially symmetrically spaced intervals about the annular flange portion. Preferably, an interior surface of the tubular aperture is radiused substantially where this surface meets the outlet apertures. Preferably, a plunger disposed in the tubular aperture and a seat which the plunger contacts to shut off fuel flow through the valve when the valve is closed are both radiused. The annular flange portion preferably includes one or more “vanes” extending into the tubular aperture.
