ABSTRACT:
Disclosed is a variable venturi type carburetor comprising a movable suction piston which changes the cross-sectional area of a venturi portion of an intake passage in response to the amount of air flowing therethrough. The suction piston has a needle entering into a stationary jet. The needle and the jet define an annular opening through which the fuel is injected into the venturi portion. The jet is connected to a fuel reservoir via a fuel supply passage. On the bottom face of the suction piston and on the inner wall of the venturi portion, members for magnetically attracting each other are mounted, respectively.
